DAYS 1-5 (NOVEMBER 5-9)

Daylight Saving Time ended and we returned to Standard Time early today. Remember to change any manual (non auto-changing) clocks if you haven’t. Sunrise is back to the earlier 6:00 a.m. hour for now and sunset is just after 4:30 p.m. today, with the former to get later and the latter to get earlier still during the course of the next several weeks, as is the case every year of course. Otherwise, weatherwise… An area of high pressure hangs on to our south today through Tuesday. Today will be fair with a diminishing amount of cloud cover with time after a weak cold front goes through the region. If you were up early you may have seen a pretty heavy dew, due to a shot of relatively higher humidity ahead of that front. Cloudiness makes a comeback Monday as the boundary comes back as a warm front and passes through the region the other way. Low pressure passes north of our region on Tuesday and drags the front back through again from the northwest as a cold front. A pre-frontal trough and the front itself may produce a couple rounds of rain showers, otherwise rainfall looks limited and it will be a mild and relatively humid day Tuesday. Chilly, dry air arrives Wednesday courtesy Canadian high pressure. The front won’t get all that far to our south before another low runs along it, but I continue to lean toward a suppression scenario with the bulk of any precipitation from this low passing to our south early Thursday, with our area just under a cloud shield for several hours before we clear again and remain chilly on Thursday.

TODAY: Partly to mostly sunny. Highs 58-65. Wind SW 5-15 MPH.

TONIGHT: Mostly clear to partly cloudy. Lows 41-48. Wind S up to 10 MPH.

MONDAY: Partly to mostly cloudy. Highs 55-62. Wind SE up to 10 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of showers overnight. Lows 48-55. Wind SW 5-15 MPH.

TUESDAY: Variably cloudy. Chance of a shower early morning and late day. Highs 60-67. Wind SW 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH.

WEDNESDAY: Sun and passing clouds. Highs 47-54. Wind NW 5-15 MPH, gusty.

WEDNESDAY NIGHT: Clouding over. Chance of rain near the South Coast late. Lows 35-42. Wind N up to 10 MPH.

THURSDAY: Cloudy start, then increasing sun. Highs 45-52. Wind N up to 10 MPH.

DAYS 6-10 (NOVEMBER 10-14)

Clouds, possible brief precipitation southern areas as another low passes to the south at the beginning of the period based on current expectations. November 11-12 weekend looks dry, breezy, and chilly in a northwesterly flow from Canada, then high pressure brings fair weather with cold nights and milder days later in the period.

DAYS 11-15 (NOVEMBER 15-19)

Trend is for mostly dry, mild weather with a high pressure ridge dominating the weather in the Northeast.

DAYS 1-5 (NOVEMBER 4-8)

High pressure sits south of our region and will stay there through Monday. This weekend and most of Monday will see dry weather, but a frontal boundary will approach the region from the northwest today and slow down, and as it washes out it will push through the area by early Sunday. Cloudiness that is most abundant today (after a nice sunrise in some areas) will diminish on Sunday which will be the sunnier of the two weekend days as a small area of high pressure noses in. Clouds make a return Monday as low pressure heads into southeastern Canada via the northern Great Lakes. A warm front will move across the region during the day, but this doesn’t look like it will produce any rainfall either. We’ll have to wait for a trough and then a cold front to produce a couple rounds of showers, early and again later Tuesday. With the cold front not due until later Tuesday, that will be a mild day as well. Wednesday, a chilly high pressure area builds in from Canada with dry weather and a gusty breeze.

TODAY: Most sun early, otherwise lots of clouds. Highs 56-63. Wind SW 5-15 MPH.

TONIGHT: Mostly cloudy. Lows 40-47. Wind SW up to 10 MPH.

SUNDAY: Most clouds early, otherwise more sun. Highs 58-65. Wind SW 5-15 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 41-48. Wind S up to 10 MPH.

MONDAY: Increasing clouds. Highs 55-62. Wind SE up to 10 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of showers overnight. Lows 48-55. Wind SW 5-15 MPH.

TUESDAY: Variably cloudy. Chance of a shower early morning and late day. Highs 58-65. Wind SW 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH.

WEDNESDAY: Sun and passing clouds. Highs 47-54. Wind NW 5-15 MPH, gusty.

DAYS 6-10 (NOVEMBER 9-13)

One or two low pressure areas will make a run at the region but should be mostly pushed to the south November 9-10. Can’t rule out a period of precipitation with details to be worked out. Dry weather mid period. Next system arrives with clouds and a rain chance toward the end of the period. Temperatures below normal.

DAYS 11-15 (NOVEMBER 14-18)

Trend is dry, cool start then a slow milder trend with high pressure dominating.

DAYS 1-5 (NOVEMBER 3-7)

High pressure to our south continues to provide generally fair weather, but now that it’s to the south, a frontal boundary to our north will get closer to the region. The “bad” news is limited as this only means more cloudiness at times today (mostly early) and more so during this weekend, but the good news is we’ll see dry weather and a modest warm-up during this time. We continue mild on Monday and the timing of the next trough, low, and frontal system seems slow enough that we get through that day rain-free, then see an episode or two of rain showers later at night and/or Tuesday from a west-to-east moving system with low pressure passing to our north.

TODAY: Early clouds, then mostly sunny. Highs 50-57. Wind SW 5-15 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 38-45. SW up to 10 MPH.

SATURDAY: Considerably cloudy. Highs 56-63. Wind SW 5-15 MPH.

SATURDAY NIGHT: Variably cloudy. Lows 40-47. Wind SW up to 10 MPH.

SUNDAY: Variably cloudy. Highs 58-65. Wind SW 5-15 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 41-48. Wind SW 5-15 MPH.

MONDAY: Increasing clouds. Highs 55-62. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of showers. Lows 45-52. Wind SW 5-15 MPH.

TUESDAY: Mostly cloudy. Chance of showers. Highs 52-59. Wind SW 5-15 MPH shifting to NW.

DAYS 6-10 (NOVEMBER 8-12)

My outlook in this period is somewhat different than medium range guidance shows at this point. Leaning toward the next system being shunted to the south about November 9 and a different low approaching our region at the end of the period after generally dry, chilly weather. Details to work out…

DAYS 11-15 (NOVEMBER 13-17)

Best shot of unsettled weather early in the period. Generally dry otherwise. Temperatures near to below normal.

DAYS 1-5 (NOVEMBER 2-6)

A high pressure area brings abundant sun today and again on Friday. This morning’s low temperatures ranged from the upper 20s in rural areas to the 30s in most areas, with a pretty widespread frost, and some freeze, with hard freeze in very limited locations. We recover slightly to the 40s today. Tonight will be another chilly one but may not get quite as low as we start to see a southwesterly air flow as the axis of high pressure shifts south, and then helps us recover to the 50s Friday. The high will stay to our south while a couple disturbances pass by to the north over the weekend. This results in milder weather but not as abundant sunshine for Saturday and Sunday, but at least we can expect dry weather to continue dominating. Monday, clouds increase ahead of the next trough and low pressure system. Depending on the speed / timing, it may turn wet by the end of the day.

TODAY: Sunny. Highs 43-50. Wind W up to 10 MPH.

TONIGHT: Clear. Lows 30-37. Wind SW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 50-57. Wind SW 5-15 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 38-45. SW up to 10 MPH.

SATURDAY: Cloud/sun mix. Highs 56-63. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 40-47. Wind SW up to 10 MPH.

SUNDAY: Sun/cloud mix. Highs 58-65. Wind SW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 41-48. Wind SW 5-15 MPH.

MONDAY: Increasing clouds. Chance of rain late day or night. Highs 55-62. Wind W up to 10 MPH.

DAYS 6-10 (NOVEMBER 7-11)

A low pressure system passing through the region brings wet weather early in the period, followed by mainly dry with temperatures near to below normal.

DAYS 11-15 (NOVEMBER 12-16)

Next trough brings higher chance of unsettled weather early to mid period, then dry weather returns. Temperatures near to below normal.

DAYS 1-5 (NOVEMBER 1-5)

Today, a wave of low pressure passes offshore, skirting Cape Cod and the Islands with a bit of rain early, otherwise an upper level inverted trough will create some scattered showers from late morning through afternoon. These showers will be mostly in the form of rain, but the air is marginally cold enough that some frozen precipitation may mix in with some of them. Tonight, high pressure builds in and we see clearing with ideal radiational cooling resulting in frost and for many areas the first freeze of the season. Exceptions will be the immediate shore line and normally milder urban centers. Thursday will be bright, cool, and tranquil under high pressure. This high sinks to the south Friday through the weekend with dry weather and a warming trend. Friday will be sunniest, and the weekend will feature some periods of cloudiness as a couple disturbances pass by to our north.

TODAY: Limited sun, dominant clouds. Early-day rain Cape Cod / Islands. Midday-afternoon scattered showers of rain, possibly mixed with sleet and/or wet snow. Highs 42-49. Wind NE-N 5-15 MPH.

TONIGHT: Clearing. Lows 27-34. Wind N under 10 MPH becoming calm.

THURSDAY: Sunny. Highs 45-52. Wind W up to 10 MPH.

THURSDAY NIGHT: Clear. Lows 30-37. Wind W under 10 MPH.

FRIDAY: Mostly sunny. Highs 48-55. Wind SW 5-15 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 38-45. SW up to 10 MPH.

SATURDAY: Cloud/sun mix. Highs 56-63. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 40-47. Wind SW up to 10 MPH.

SUNDAY: Sun/cloud mix. Highs 58-65. Wind SW 5-15 MPH.

DAYS 6-10 (NOVEMBER 6-10)

Unsettled weather odds highest on November 7 & 10. Fair weather odds higher other days. Temperatures near to below normal.

DAYS 11-15 (NOVEMBER 11-15)

Leaning toward the greatest chance for unsettled weather during this middle portion of this period. Temperatures near to below normal.

DAYS 1-5 (OCTOBER 31 – NOVEMBER 4)

October comes to an end with a dry but chilly Halloween. We’ll see plenty of sun today but there will be a strip of clouds cutting across southeastern areas during the day which will start to increase by day’s end once again. This is due to air lifting over the frontal boundary that went by us as a cold front late Saturday then was the avenue for Sunday’s & Monday’s rainfall. But we have a well-timed break for today, including this evening’s trick-or-treat which will take place with dry weather, but temperatures from the lower 40s to upper 30s across the area. At least it will not be all that windy. Wednesday will be an unsettled day to welcome the month of November. Another wave of low pressure moves along the frontal boundary just to our southeast, passing far enough offshore to bring the steadiest rain to Cape Cod and the Islands, with this rain shield probably up about as far as the I-95 belt. With marginal temperatures / cold air, can’t rule out a mix with wet snow or sleet briefly in some areas, but no accumulation will occur. Additionally, an upper low moving across the region and a northeast wind can also combine for additional showers of mostly rain (maybe some mix) elsewhere in the region mainly during the morning through midday hours. Later Wednesday we dry out as the entire system pulls off to the east. Thursday and Friday will be fair and cool with high pressure building in. Saturday may start with lots of clouds as a warm front moves through, but this looks like a dry frontal passage, and would lead to a milder day with the return of sunshine, based on expecting timing.

TODAY: Sunshine, but limited at times South Coast to MA South Shore. Highs 47-54. Wind NW 5-15 MPH, diminishing.

TONIGHT: Clouds increase and thicken. Rain arrives overnight South Coast to MA South Shore, up to around I-90 / I-95 by dawn, may mix with wet snow and/or sleet in some locations. Lows 33-40. Wind N-NE up to 10 MPH.

WEDNESDAY: Cloudy start with early-day rain most likely RI and southeastern MA, may briefly be mixed with wet snow and/or sleet. Lots of clouds linger thereafter with a few rain showers, some possibly mixed with snow/sleet. Highs 42-49. Wind NE-N 5-15 MPH.

WEDNESDAY NIGHT: Clearing. Lows 30-37. Wind N-NW 5-15 MPH.

THURSDAY: Sunny. Highs 46-53. Wind NW 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 28-35. Wind W under 10 MPH.

FRIDAY: Mostly sunny. Highs 48-55. Wind W up to 10 MPH.

FRIDAY NIGHT: Clouding up. Lows 38-45. Wind calm.

SATURDAY: Cloudy start, then sun returns. Highs 56-63. Wind SW up to 10 MPH.

DAYS 6-10 (NOVEMBER 5-9)

Cold front approaches November 5 with some clouds but continued mild weather, then cooler November 6 with no more than a passing rain shower. Stronger low pressure / frontal system November 7 with better rain chance. Dry, cooler to colder weather returns November 8 with windy conditions, then more tranquil but still chilly with fair weather November 9 as high pressure builds in.

DAYS 11-15 (NOVEMBER 10-14)

Leaning toward the greatest chance for unsettled weather during this middle portion of this period. Temperatures near to below normal.

DAYS 1-5 (OCTOBER 30 – NOVEMBER 3)

A wave of low pressure prolongs our unsettled weather today, with periods of rain. The frontal boundary that the low is riding along lifts northward far enough to get the South Coast region and possibly up to about I-90 into the “warm sector” so those areas will be mildest today before the front heads back south behind the low. The rain ends as this happens later today, and this sets us up for a dry but chilly Halloween. But another low pressure wave will be traveling along that frontal boundary. This one passes a bit further south and is likely to only clip areas from about I-95 southeastward with precipitation Wednesday morning – mainly rain, but can’t rule out some wet snowflakes or ice pellets mixing in for a brief time. This exits and sun returns before the day is over, then high pressure dominates with fair weather Thursday and Friday along with chilly air.

TODAY: Cloudy. Periods of rain, ending late. Highs 48-55. Wind NE-N 5-15 MPH.

TONIGHT: Clearing. Lows 33-40. Wind N-NW 5-15 MPH.

TUESDAY: Sunshine followed by clouds. Highs 47-54. Wind NW 5-15 MPH.

TUESDAY NIGHT: Cloudy. Rain arrives South Coast late evening, up to around I-90 / I-95 overnight, may mix with wet snow and/or sleet briefly. Lows 33-40. Wind N-NE up to 10 MPH.

WEDNESDAY: Cloudy start with early-day rain most likely RI and southeastern MA, may briefly be mixed with wet snow and/or sleet, then clouds thin for some sun as the day goes on. Highs 43-50. Wind NE-N 5-15 MPH.

WEDNESDAY NIGHT: Clearing. Lows 31-38. Wind N-NW 5-15 MPH.

THURSDAY: Sunny. Highs 46-53. Wind NW 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 28-35. Wind W under 10 MPH.

FRIDAY: Mostly sunny. Highs 48-55. Wind W up to 10 MPH.

DAYS 6-10 (NOVEMBER 4-8)

Looking ahead to the weekend of November 4-5, it looks rain-free and milder. A warm front may produce clouds to start, and an approaching cold front may bring more clouds to end it. This front nearby November 6 brings a better rain shower threat and another low pressure wave and upper low may combine for more unsettled weather and below normal temps November 7 before it clears late in this period.

DAYS 11-15 (NOVEMBER 9-13)

Dry, cooler early period, return of unsettled weather possible later period. Still a low confidence forecast.

DAYS 1-5 (OCTOBER 29 – NOVEMBER 2)

Summer’s over (again), and now we’re back to reality – a much cooler and unsettled weather pattern. However, well-timed dry weather is expected for Halloween. Temperatures today will be as much as 20 to 30 degrees cooler than those of yesterday, under a thickening cloud cover with eventual rain, once dry air at the surface is overcome. Today’s rainfall comes courtesy a mid to upper level disturbance bringing warmer air aloft into the region. A second disturbance joins the party Monday in the form of a wave of low pressure developing on a frontal boundary and moving east northeast through the region. The front itself may lift far enough north for areas south of I-90 to get into the warm sector before the front sags back to the south. Periodic rain can be expected through at least midday Monday, with a drying trend following later in the day and especially Monday night. Tuesday looks dry, despite any sun giving way to more clouds in advance of the next low pressure wave. But that timing of that system allows dry weather to dominate through the evening hours, but with very cool air. And then the next wave of low pressure moves by to our south and southeast very late Tuesday night into Wednesday. The trend for this system on medium range guidance has been a little to the south, with those simulations indicating the greatest chance of precipitation would be in southeastern MA and RI earlier Wednesday, with limited to no precipitation the west and north. The cold air around is marginal enough to support frozen precipitation for a period of time, but this would favor higher elevations to the north and west of Boston, so if the precipitation shield is further south and east, the odds of seeing anything frozen go way down. This is the way I’m leaning at this point in time. In either case, by Thursday we’ll be back in fair and chilly weather as high pressure moves in.

TODAY: Clouding up. Periods of light rain midday on. Highs 50-57. Wind N-NE up to 10 MPH except up to 15 MPH over southeastern MA.

TONIGHT: Cloudy. Periods of rain. Lows 41-48. Wind NE 5-15 MPH.

MONDAY: Cloudy. Periods of rain, ending late. Highs 48-55. Wind NE-N 5-15 MPH.

MONDAY NIGHT: Clearing. Lows 33-40. Wind N-NW 5-15 MPH.

TUESDAY: Sunshine, late clouds. Highs 47-54. Wind NW 5-15 MPH.

TUESDAY NIGHT: Cloudy. Rain arrives South Coast late evening, up to around I-90 / I-95 overnight. Lows 35-42. Wind N-NE up to 10 MPH.

WEDNESDAY: Cloudy start with early-day rain most likely RI and southeastern MA then clouds may break for sun by later in the day. Highs 43-50. Wind NE-N 5-15 MPH.

WEDNESDAY NIGHT: Clearing. Lows 35-42. Wind N-NW 5-15 MPH.

THURSDAY: Sunny. Highs 50-57. Wind NW 5-15 MPH.

DAYS 6-10 (NOVEMBER 3-7)

Dry weather to start the period with a warming trend for temperature. Unsettled weather at times thereafter as a frontal boundary will be nearby along with variable temperatures – details to be fine-tuned over time.

DAYS 11-15 (NOVEMBER 8-12)

Dry, cooler early period, return of unsettled weather possible later period. Low confidence forecast though with no real detail to be attempted too far in advance.

DAYS 1-5 (OCTOBER 28 – NOVEMBER 1)

November has made it into the 5-day forecast! And when we get there, it’ll feel like it! In fact, it’ll start to feel a bit like that even before we get there. But let’s not get too far ahead of ourselves. Before that happens, we have one more feel-of-summer days to enjoy today. This is the day that Boston can top a record high, because today’s is a few degrees lower than the previous couple that they fell shy of. A high of 82 at Logan today will establish a new record, and I figure they may get close at least, likely tie it, and possibly break it. The chance goes up as a west wind picks up speed and helps enhance the down slope effect which warms the air heading from the hills to the coastal plain. We’ll see how it goes. Otherwise our warmer than normal day will be punctuated by plenty of sun, but later in the day you’ll notice some clouds heading across the sky from west northwest to east southeast, and a couple of these, particularly in southern NH and/or northern MA, may produce a few light rain showers, albeit brief wherever they may occur. This is a cold front, and it opens the door to a different feel. Considering today’s high temps around 80 for many, after that front goes by tonight we’ll see quite the temperature fall as many areas land in the 40s by morning. And Sunday, we don’t see a whole lot of temperature recovery, so my previous overly-optimistic temperature forecast will have to be adjusted quite a bit. Sorry! And once the cool air is in, it’s hanging around for a while. We also have a wave of low pressure to come along the front after it goes by, and brings us some wet weather later Sunday through Monday. Initially the rain will struggle to overcome some dry air so a good portion of Sunday will stay rain-free, with just patches of light rain moving into the region during the afternoon. A more saturated atmosphere Sunday night and Monday will allow for occasional to frequent periods of rainfall, which will taper off later Monday as the low pressure wave starts to move beyond the region. This will allow dry weather to return for Tuesday – Halloween – but with the arrival of a reinforcing shot of polar air, it’s going to be a chilly trick-or-treat on Tuesday evening. We’ll already be watching another wave of low pressure moving up along the front that still sits not far to the south, so while I do think any precipitation will hold off for All Hallow’s Eve activities, the overnight hours into Wednesday look overcast and wet with more rain, and it can be cold enough for some mix/frozen precipitation to occur for a period of time over interior higher elevations – just a little memo from mother nature about winter drawing closer. Either way, with that system around, the high temps Wednesday will feel more like late November rather than the first of the month.

TODAY: Mostly sunny, but some late-day clouds may produce a sprinkle of rain southern NH and/or northern MA. Highs 76-83 except cooler South Coast. Wind SW 5-15 MPH, higher gusts, shifting to W.

TONIGHT: Partly cloudy early, then clearing. Lows 45-52. Wind W 5-15 MPH, a few higher gusts, shifting to NW.

SUNDAY: Clouding up. Patchy light rain in the afternoon. Highs 48-55. Wind NW 5-15 MPH shifting to NE.

SUNDAY NIGHT: Cloudy. Periods of rain. Lows 42-49. Wind NE 5-15 MPH.

MONDAY: Cloudy. Periods of rain, ending late. Highs 52-59. Wind NE-N 5-15 MPH.

MONDAY NIGHT: Clearing. Lows 33-40. Wind N-NW 5-15 MPH.

TUESDAY: Sunshine, late clouds. Highs 47-54. Wind NW 5-15 MPH.

TUESDAY NIGHT: Clouding over. Overnight rain arriving, may be mixed with sleet and/or snow over interior higher elevations of MA and southwestern NH. Lows 35-42. Wind N-NE up to 10 MPH.

WEDNESDAY: Cloudy. Rain likely, may be mixed with some frozen precipitation for a while interior higher elevations mainly north central MA and southwestern NH. Highs 42-49. Wind NE 5-15 MPH.

DAYS 6-10 (NOVEMBER 2-6)

Dry weather returns with below normal temperatures early in the period. Moderating temperature mid period but a warm front may bring clouds followed by a cold front bringing a brief rain chance before dry, cooler weather returns at the very end of the period, based on current timing.

DAYS 11-15 (NOVEMBER 7-11)

A weak weather system coming through early in the period with some unsettled weather, then a return to dry weather and a cool-down followed by another warm-up.

DAYS 1-5 (OCTOBER 27-31)

Two more days that feel like summer come to us courtesy a strong ridge of high pressure in the eastern US, and then this ridge weakens and sinks to the south to allow a frontal boundary to slide across the region from northwest to southeast. The front passes by with little fanfare other than a few clouds and a wind shift Saturday evening. After this, we see a cooling trend from Sunday through Tuesday. A wave of low pressure moving along the frontal boundary will bring some wet weather at times later Sunday and Monday. A second low pressure wave approaching may increase the cloud cover later Tuesday, but right now the Halloween outlook is dry, just quite cool.

TODAY: Mostly sunny. Highs 75-82, a little cooler South Coast. Wind SW 5-15 MPH.

TONIGHT: Mostly clear. Fog patches in low elevations. Lows 53-60. Wind SW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 75-82, a little cooler South Coast. Wind SW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy, then clearing. Lows 48-55. Wind SW 5-15 MPH shifting to NW.

SUNDAY: Increasing clouds. Late-day rain possible. Highs 60-67. Wind NW to N up to 10 MPH.

SUNDAY NIGHT: Cloudy. Periods of rain. Lows 45-52. Wind N-NE 5-15 MPH.

MONDAY: Cloudy. Periods of rain, ending late. Highs 52-59. Wind NE-N 5-15 MPH.

MONDAY NIGHT: Clearing. Lows 33-40. Wind N-NW 5-15 MPH.

TUESDAY: Sunshine, late clouds. Highs 50-57. Wind NW 5-15 MPH.

DAYS 6-10 (NOVEMBER 1-5)

Watching for a wave of low pressure at the start of the period to bring a period of wet weather, mainly rain but may include some mix/frozen for a brief time somewhere away from the coast. This will be followed by a dry stretch, initially chilly, then with a temperature moderation as high pressure approaches from the west then sinks to the south.

DAYS 11-15 (NOVEMBER 6-10)

A weak weather system coming through early in the period with some unsettled weather, then a return to dry weather and a chill-off followed by another warm-up.

DAYS 1-5 (OCTOBER 26-30)

Our weather is going to undergo a significant change before this 5-day period ends, but it starts out with 3 more days of anomalous warmth, due to a strong ridge of high pressure over the southeastern US. Being near the northern edge of this ridge, we see lots of clouds in our sky, but as the ridge nudges northward it will help push those clouds away later today and even more so for Friday and Saturday. Those 2 days, other than the lower late October sun angle and changing foliage, will remind you a bit of summer. But “summer’s” days are numbered. As high pressure ridging weakens and starts to retreat southward, a frontal boundary held at bay will finally be able to move through the region from northwest to southeast Saturday night and Sunday, introducing the beginning of a significant cool-down. The chilly air won’t come blasting in all at once though. Sunday will still be mild in comparison to normal, just not as warm as Saturday. We’ll also see the return of cloudiness and eventually a shower chance as a wave of low pressure along the frontal boundary approaches our region late in the day. Based on current timing and more reliable guidance, I think we will get through a fair amount of the day Sunday without a wet weather threat, and that most of the rainfall from this wave will occur Sunday night and the first half of Monday. Later Monday we should see a drying trend with chilly air becoming more established as the low pressure wave departs the region.

TODAY: Mostly cloudy to partly sunny. Highs 68-75, coolest South Coast. Wind SW 5-15 MPH.

TONIGHT: Partly cloudy to mostly clear. A few fog patches in low elevations. Lows 50-57. Wind SW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 71-78, a little cooler South Coast. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Fog patches in low elevations. Lows 50-57. Wind SW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 72-79, a little cooler South Coast. Wind SW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Mostly clear. Lows 48-55. Wind SW 5-15 MPH shifting to NW.

SUNDAY: Increasing clouds. Late-day rain possible. Highs 60-67. Wind NW to N up to 10 MPH.

SUNDAY NIGHT: Cloudy. Periods of rain. Lows 45-52. Wind N-NE 5-15 MPH.

MONDAY: Cloudy with rain likely in the morning. Breaking clouds afternoon. Highs 52-59. Wind NE-N 5-15 MPH.

DAYS 6-10 (OCTOBER 31 – NOVEMBER 4)

Temperatures below normal during this period. Current outlook is dry for Halloween, then watching a wave of low pressure with a precipitation chance (mainly rain but some frozen precipitation may be involved especially inland higher elevations if the coverage is great enough) around November 1, before dry weather returns with below normal temps, then a moderation. Clouds and a shower threat may return as early as the very end of the period.

DAYS 11-15 (NOVEMBER 5-9)

Unsettled weather possible at the start of the period before a push of milder air and fair weather. A brief rain shower chance introduces cooler weather again before the end of the period.

DAYS 1-5 (OCTOBER 25-29)

A mild to warm pattern is ours for the balance of this week, even into the weekend, and possibly even through the entire weekend to some degree (no pun intended). The big weather driver is a large upper level high pressure ridge to the south of New England and associated surface high pressure. We’ll see a couple disturbances bringing clouds to our region, but no rain threat. It won’t be until sometime over the weekend that a frontal boundary will make a charge at the region, probably to be thwarted by the ridge. This presents our only opportunity to see showers on Sunday, but even much of that day can turn out to be rain-free, but likely cooler than Saturday, which may be the warmest of this entire stretch.

TODAY: Sunny start, then variably cloudy. Highs 64-71. Wind SW 5-15 MPH, higher gusts.

TONIGHT: Variably cloudy. Lows 48-55. Wind SW 5-15 MPH.

THURSDAY: Partly sunny. Highs 68-75. Wind SW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Lows 48-55. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 30 – NOVEMBER 3)

A general westerly flow pattern will rule our weather from the end of October into the first few days of November. Upper level high pressure to the south weakens and allows the frontal boundary to push through sometime in last couple days of the month. This front does produce a shower threat and maybe a period of rain (more likely October 30) if a wave of low pressure can form along it. As the front takes its time getting to our south, we’ll have to watch for an additional wave of low pressure with a precipitation threat sometime in the November 1-2 time frame as it turns colder, and then fair, chilly weather should take over by period’s end.

DAYS 11-15 (NOVEMBER 4-8)

A temperature rebound with milder weather in this period, but a bit early to time any unsettled weather threats, though leaning toward the early portion of the period for that with the initial return of milder air.

DAYS 1-5 (OCTOBER 24-28)

Overnight, there were some lingering patches of stratocumulus clouds around, but the shield of high and mid level clouds held off long enough to allow temps to fall to 35-40 over the interior low elevations, where some frost has likely occurred for the first time this season. Temperatures will stay above 40 in urban areas and along the coast. A batch of clouds with warm air moving in aloft will move through the region this morning and midday but give way to more sun as the day goes on, and this is the start of a warming trend that will last through late this week, along with dry weather. This will be caused by a significant ridge of high pressure and a related surface low to our south. We will have to deal with periods of cloudiness with disturbances moving along the jet stream just to our north. Right now, it continues to look like a surface frontal boundary separating our mild air from colder Canadian air will stay to our north into the weekend. There is no rain in the forecast for the WHW region for the next 5 days.

TODAY: Variably cloudy through midday then becoming mostly sunny. Highs 57-64. Wind calm, then SW up to 10 MPH.

TONIGHT: Mostly clear. Lows 43-50. Wind SW 5-15 MPH.

WEDNESDAY: Partly cloudy. Highs 64-71. Wind SW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Variably cloudy. Lows 48-55. Wind SW 5-15 MPH.

THURSDAY: Partly sunny. Highs 68-75. Wind SW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Lows 48-55. Wind SW 5-15 MPH.

FRIDAY: Partly cloudy. Highs 71-78. Wind SW 5-15 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 50-57. Wind SW 5-15 MPH.

SATURDAY: Mostly sunny. Highs 72-79. Wind SW 5-15 MPH, higher gusts.

DAYS 6-10 (OCTOBER 29 – NOVEMBER 2)

A general westerly flow pattern will rule our weather from the end of October into the first couple days of November. We’ll see upper high pressure weaken and allow the frontal boundary to the north to get into our region early in the period. This front, which may have a couple weak waves of low pressure traveling along it, will be responsible for a rain shower threat from later October 29 to early October 31, based on current timing, but adjustments will take place to pin down more specific timing. However, this does not look like a significant rain-producing situation. Temperatures trend cooler to colder. Watch for one more potential low pressure wave traveling by the region with a precipitation threat toward the end of the period, but cannot be confident of that this far in advance.

DAYS 11-15 (NOVEMBER 3-7)

Overall pattern looks dry, chilly to start, then trending milder during this period, as high pressure dominates, first sending a chilly northwesterly air flow in, then settling to the south with a more west to southwest air flow thereafter.

DAYS 1-5 (OCTOBER 23-27)

And now for something different. Upper level low pressure waves bye-bye today and heads off through eastern Canada. Meanwhile, to our southwest, high pressure ridging builds across the southeastern US early this week and establish itself pretty firmly through mid week and even beyond. This is going to play the biggest role in our weather this week, initiating a warm up that hangs around a while. Since we won’t be under the ridge itself, more on the edge of it, we’ll still be dealing with some systems moving along the jet stream, but these are also instrumental in helping to bring in the warmer air too, and what they won’t do this time is dump a lot of rain on us. First, we keep a northwest breeze and sun/cloud mix today as the last of the upper low impacts the region. Tonight, while we set up good radiational cooling and a likely frost for interior areas, some of this may be limited by a temperature-capping advancing cloud deck as warmer air moves in aloft. These clouds will hang around early Tuesday as a warm front passes by quietly, then we’ll increase the sun and see a nice temperature recovery after the chilly start. It will cool down again Tuesday night with high pressure over the region and a clear sky but any frost would be confined to interior valley locations, along with patches of ground fog. Mid to late week, high pressure shifts offshore, and we’ll be in a southwesterly air flow with fair weather and above normal temperatures, though some clouds will move through from time to time with energy traveling along the jet stream.

TODAY: Sun/cloud mix. Highs 53-60. Wind NW 5-15 MPH.

TONIGHT: Clear evening. Clouds increase overnight. Areas of frost interior suburban and rural areas. Fog patches form in low elevations and over ponds. Lows 33-40 except 40-47 immediate shoreline and urban locations. Wind calm.

TUESDAY: Lots of clouds early, then sunshine. Highs 56-63. Wind calm early, then SW up to 10 MPH.

TUESDAY NIGHT: Clear. Lows 43-50. Wind SW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 63-70. Wind SW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Partly cloudy. Interior lower elevation fog patches. Lows 45-52. Wind SW diminishing to under 10 MPH.

THURSDAY: Partly sunny. Highs 68-75. Wind SW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Lows 48-55. Wind SW 5-15 MPH.

FRIDAY: Partly cloudy. Highs 71-78. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 28 – NOVEMBER 1)

Overall a westerly flow pattern will dominate the weather. What we will have to fine-tune is the position of a frontal boundary that will exist between the warmer ridge of high pressure trying to hang on to our south while colder air makes attempts to move down from Canada. So some up and down temps are likely, but leaning toward a mild to warm start then a step by step cool down. The frontal boundary is not expected to produce much other than a couple rounds of rain showers, as it stands now. Just have to work out the timing of these threats. For now lean toward October 29-30.

DAYS 11-15 (NOVEMBER 2-6)

A more northwesterly flow should allow for chilly air from Canada to become more dominant during the early days of November, along with a mostly dry pattern.

DAYS 1-5 (OCTOBER 22-26)

Low pressure continues to impact the region today, but it will be a mostly fair kind of low pressure impact. While the deck of clouds associated with yesterday’s wet weather has now lifted to our northeast and north, it will rotate back through here this evening along with a weakening area of rain showers, really becoming just light showers/sprinkles as it moves through. Before that, our sunny start to Sunday will end up as a sun/cloud mix as we pop diurnal cumulus clouds. Behind all this, another sun/cloud mix day is expected Monday, along with breezy and chilly conditions. High pressure builds in Monday night with a quick-falling temp, but also quickly happening will be an advancing high to mid level cloud deck ahead of a warm front. If this arrives quickly enough, it may put the brakes on the temperature drop pre-dawn and prevent some areas from reaching frost levels, but I still expect a fair amount of the region to see it. These clouds will be around, limiting and filtering the sun on Tuesday as the warm air advances above us first. When we’ll feel it at the surface more prominently is on Wednesday, when we’ll be in a southwesterly air flow of mild air. And this time it’s not just a one-day warm-up, but it continues through Thursday, along with fair weather in general. Patchy clouds may visit us again Thursday as a weakening frontal boundary tries to push into the region, but is thwarted by a ridge of high pressure.

TODAY: Sunny start, then clouds develop limiting the sun from midday on. Highs 52-59. Wind W 10-20 MPH, higher gusts.

TONIGHT: Mostly cloudy. Scattered to isolated rain showers north to south. Lows 42-49. Wind NW 10-20 MPH, higher gusts.

MONDAY: Sun and passing clouds. Highs 52-59. Wind NW 10-20 MPH, gusty.

MONDAY NIGHT: Clear through evening then increasing high clouds overnight. Fog patches in lowest elevations and especially over lakes/ponds. Frost likely especially outside urban centers and away from the immediate shoreline. Lows 35-42, 28-35 in normal cold spots. Wind NW 5-15 MPH early, diminishing to calm.

TUESDAY: Partial sunshine. Highs 56-63. Wind calm early, then SW up to 10 MPH.

TUESDAY NIGHT: Clear. Lows 43-50. Wind SW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 63-70. Wind SW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Mostly clear. Ground fog patches late evening / overnight. Lows 45-52. Wind SW diminishing to under 10 MPH.

THURSDAY: Mostly sunny to partly cloudy. Highs 65-72. Wind SW 5-15 MPH, higher gusts.

DAYS 6-10 (OCTOBER 27-31)

During the final days of October, I expect a westerly flow pattern with the potential for one or two frontal boundaries to come through the region. Currently, the indication is that moisture for these will be limited and the bigger impact will be for them to eat away at the mild pattern and turn us cooler.

DAYS 11-15 (NOVEMBER 1-5)

Cautiously confident in going with a continued westerly flow pattern and a trend to below normal temperatures, but still need to watch for moisture from the south and west that some guidance may not be seeing as of yet.
