DAYS 1-5 (OCTOBER 31 – NOVEMBER 4)

Discussion…

A rare sight greeted early risers today in a good portion of the WHW forecast area: snow covered landscape, much of it still foliated. We’re used to seeing this with some of the late foliage like oaks, or evergreen type trees, but it’s rare to see that much snow on trees with colorful leaves that haven’t dropped them yet, and that’s exactly what we had. I was fortunate enough to take a walk at a local pond this morning to witness some of this close-up, and photograph some of it (although poor planning meant that I not only ran out of storage space, but battery too, before the end of my walk – oops, about as good as my forecast was for yesterday’s storm, but that’s life!) … Now, as the sun warms the landscape enough today to rid the trees of the snow, and more leaves come down with that, we will only recover to the 40s as a chilly high pressure area moves overhead, but this is good news for any cities and towns holding trick or treating this evening, as winds will be light despite the chill. Last year, if you recall, it was very mild, but also quite windy, and showery in some locations. Tonight will have 2 distinctive parts to it. This evening, we’ll see quick radiational cooling especially where snow remains on the ground under a mostly clear sky with just some high clouds streaming in above, decorative for the rising full Halloween moon, a blue moon (the second full moon of the month, not actually blue), also known as the full Hunter’s moon. Our low temperatures will be reached before midnight. During the overnight hours, a southerly air flow will strengthen and we’ll not only have increasing high & mid level clouds with the a warm front coming toward the region but we’ll have lower clouds coming up via the waters just south of New England, and the temperature will rise gradually. Also, don’t forget, tonight is the night we turn the clocks back, ending Daylight Savings Time and going back to Standard Time, technically occurring at 2 a.m. Sunday morning. So remember to change any clocks that do not automatically adjust! You get the extra hour of sleep if you want it, but our sunset will also occur before 5 p.m. after today onward into early 2021. Back to the weather… A disturbance moving north northeastward may bring a few rain showers to southeastern MA around dawn to about mid morning on Sunday, but the majority of Sunday morning and the first half of the afternoon will just feature a lot of clouds but not really any rainfall. Later in the day though, as a strong cold front approaches from the west, there should be a decent swath of showers, and even the risk of some embedded thunder, moving in from the west, that will cross the region during the evening before pushing offshore overnight. This will introduce a much colder air mass on Monday, of arctic origin although somewhat modified. Nevertheless, Monday is going to be a windy and cold day with some sun but also a fair amount of passing clouds, and some of these clouds may produce a rain or snow shower. Later Monday night into the early hours of Tuesday (to around dawn), another disturbance will move through the area from northwest to southeast, producing a few snow showers, and maybe even a brief snow squall. This will reinforce our cold air for Election Day Tuesday. If you have doing in-person voting, expect a breezy, bright, but chilly day with temperatures in the 30s much of the time (peaking in the lower 40s for some areas). There will, even be some wind chill making it feel colder. Tuesday night will be a cold one with high pressure moving overhead, but Wednesday, after a cold start, we’ll see a nice temperature recovery as the high center shifts to the southeast and a west to southwest wind develops, bringing air from a milder source region into our area.

DAYS 6-10 (NOVEMBER 5-9)

This period looks mainly dry, but temperatures are going to be dependent on wind direction and whether high pressure to the south of New England or in eastern Canada has a stronger influence. Currently I expect us to be influenced by high pressure to the south with above normal temperatures November 5-7, then high pressure from Canada with a cooler November 8-9.

DAYS 11-15 (NOVEMBER 10-14)

Lower confidence in what happens during this period. Looks like a brief warm up, rain showers, then a chill-down through Veterans Day, a possible wave of low pressure with rain/mix/snow threat around November 12-13, then dry weather to end the period. A lot of uncertainty here so don’t put too much stock in this outlook right now.

Discussion…

About 10 days ago I told a coworker many of us would see our first snowflakes before October was over. Well, many of you will indeed see that today. But this is not going to be a big snowstorm either. No repeat of 2011. And let’s get our priorities straight. People “freak out” (don’t know why) over relatively minor events these days, but for most of you, snow is not going to be the problem today. The greater danger comes tonight when temperatures fall into the 20s before the ground has a chance to dry off, even though the snow (and rain to the southeast) will have ended hours before. This is a recipe for black ice, and it would have been an issue even with out the snow. So don’t blame the snow for the ice that forms tonight. It’s time we got back to thinking about weather in a more practical sense. Getting lost in the drama of “flakes falling from the sky” prevents a lot of useful information from actually being heard. So be careful tonight if you go out. If you read this, and still do the icy slip n’ slide, don’t say you were not warned. So onto the rest of the weather. We have our little winter preview event as cold air meets departing low pressure today, then that cold air and black ice tonight. Thankfully as high pressure settles over the region on Saturday, despite a very cold start, the dry will “warm” back to the 40s with very dry air which will allow those icy patches to disappear. Saturday evening, for any outdoor Halloween activities, expect a sky that shows some high clouds arriving just in time to accent the rising full moon, the second one this month, the “blue moon” (not actually blue), or the Hunter’s moon. During the late night, expect more clouds and a temperature that may rise slightly as the wind begins to blow from the south. A warm front passes the region early Sunday and a cold front then approaches late in the day, but doesn’t pass through until Sunday night with its rain showers. Also, don’t forget that this is also the weekend we switch from Daylight Savings Time back to Standard Time as the clocks go back 1 hour at 2 a.m. Sunday. I’ve noticed a lot of folks lately having gotten into the habit of calling “Standard Time” by the name “Daylight Savings Time”. No. That’s what we are coming off of, and going BACK to Standard Time. Spread the word. Let’s call things what they are. And speaking of getting back to things, back to the weather I go, and back to the cold air we go on Monday and Tuesday with a nice delivery from the arctic via Canada. A few snow showers may accompany the incoming cold on Monday, but nothing series in the snow department. Tuesday, Election Day, looks dry, but there may be some areas that never get out of the 30s – so between today and that day, we’re going to see a couple of mighty chilly days for this time of year…

Details…

Discussion…

Today, you get spared a long discussion and instead just get this quick summary, because there is not really any change to my thoughts on this forecast. Low pressure passes south of the region tonight and Friday, starting as rain, which will be somewhat beneficial but not as much as some model forecasts have been – another few chips taken out of the drought. Colder air flips the rain to snow first in higher elevations north and west of Boston then eventually toward the city as the precipitation shield gets ready to depart during Friday. Minor snowfall accumulation on the order of a coating to 2 inches take place, greatest in higher elevations well north and west of Boston before things come to an end, and while most of any snow melts away later Friday, even with cold air moving in, some wet ground and puddles will remain and that sets up a good chance for ice patches Friday night as temperatures fall below freezing pretty much regionwide. No changes to the weekend with a chilly but tranquil Halloween, a full moon rising in the evening before clouds arrive, then a milder, breezy Sunday with a rain shower risk as a warm front passes and a cold front approaches. This cold front will bring a fresh shot of cold air by Monday.

Details…

TODAY: Cloudy. Rain arriving southwest to northeast. Highs 46-53. Wind W under 10 MPH shifting to N.

TONIGHT: Overcast. Periods of rain, may mix or turn to snow southwestern NH and north central MA overnight. Lows 34-41. Wind NE 5-15 MPH, higher gusts especially in coastal areas.

FRIDAY: Overcast morning with rain except mix/snow likely especially northwest of I-95 with minor accumulation favoring higher elevations of north central MA and southern NH (coating to 2 inches maximum). Mostly cloudy afternoon with a passing rain or snow shower possible. Highs 38-45. Wind NE shifting to NW increasing to 10-20 MPH with higher gusts.

FRIDAY NIGHT: Clearing. Lows 21-28 except around 30 urban centers. Wind NW diminishing to under 10 MPH.

SATURDAY: Sunny. Highs 42-49. Wind N 5-15 MPH.

SATURDAY NIGHT: Clear evening. Increasing clouds overnight. Lows 28-35 evening then a slow temperature rise overnight. Wind variable under 10 MPH evening becoming S up to 10 MPH overnight.

SUNDAY: Mostly cloudy. Chance of rain showers, especially in the afternoon. Highs 52-59. Wind S 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy with rain showers during the evening. Partly cloudy overnight. Lows 33-40. Wind S 10-20 MPH shifting to W.

MONDAY: Sun and passing clouds. Slight risk of a rain or snow shower. Highs 40-47. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (NOVEMBER 3-7)

In the latest “the models really suck” example, we have some light rain around the region this morning from a disturbance that was basically missed inside 36 hours by a lot of short range guidance and that I had to correct my forecast for yesterday. Not that the rain is a bad thing, any drops of rain we get we’ll take, although this particular episode is basically negligible as far as drought relief goes. At least we have a shot at something a tiny bit more beneficial occurring before this week is over. The focus has been misguided on this upcoming system, born of a combination of energy coming from the southwest and the moisture from a Gulf of Mexico tropical system. It’ll be rather fast-moving, and suppressed a bit further south than guidance had been showing, and while that will allow some beneficial rainfall, it will probably end up coming in at under 1 inch for most areas. But what about the snow?!?! Snow in October, for one thing, is not totally unusual. Having significant measurable snow outside of the mountains is far less common than seeing flakes that amount to nothing or minor accumulation. This event coming up will fall into the latter category for the WHW forecast area. But what you will be impacted by far more than any snowflakes that fall is the stinging chilly breeze that will be hitting you in the face if you’re outside on Friday afternoon and evening, delivering a modified piece of a very cold air mass that has been plaguing much of western and central Canada and the western US, setting records all over the place and even causing a very early season ice storm pretty far to the south in the US Plains States. The good news here is we won’t see any ice storms, but we may see some black ice on Friday night as the temperature drops below freezing. Any wet ground or puddles left behind will likely freeze up, so with the area not being used to this, it’s something to keep in mind if you are heading out. All it takes is one small patch of ice under one foot to result in a butt landing, or worse. So use caution. In addition, basically anybody who has escaped a frost/freeze up to this point will see it happen finally on Friday night / Saturday morning as the temperature falls below freezing basically everywhere and into the 20s in many areas, thus ending the growing season once and for all. Onto the weekend we go next. Saturday, Halloween, a full moon (the second one of the month), and we’ll have high pressure sitting over us with dry, tranquil, but cold weather. Any towns/cities that will be having trick or treating Saturday evening will be doing so under a clear sky, a bright rising moon, temperatures in the 30s, but light wind. High pressure moves offshore by Sunday and warm front goes by the the morning before a cold front approaches the region from the west later in the day. This results in a milder but breezy, cloudier day, along with the risk for some rain shower activity.

Details…

TODAY: Cloudy. Periods of light rain this morning. Highs 50-57. Wind E under 10 MPH shifting to S.

TONIGHT: Variably cloudy. Lows 41-48. Wind S under 10 MPH shifting to W.

FRIDAY: Overcast morning with rain except mix/snow likely especially northwest of I-95 with minor accumulation favoring higher elevations of north central MA and southern NH (coating to 2 inches maximum). Mostl cloudy afternoon with a passing rain or snow shower possible. Highs 38-45. Wind NE shifting to NW increasing to 10-20 MPH with higher gusts.

FRIDAY NIGHT: Clearing. Lows 21-28 except around 30 urban centers. Wind NW diminishing to under 10 MPH.

SATURDAY: Sunny. Highs 42-49. Wind N 5-15 MPH.

SATURDAY NIGHT: Clear evening. Increasing clouds overnight. Lows 28-35 evening then a slow temperature rise overnight. Wind variable under 10 MPH evening becoming S up to 10 MPH overnight.

SUNDAY: Mostly cloudy. Chance of rain showers, especially in the afternoon. Highs 52-59. Wind S 5-15 MPH.

DAYS 6-10 (NOVEMBER 2-6)

A strong cold air delivery November 2 with wind and maybe a passing snow shower early and again later at night. Dry, chilly November 3 after a brief snow shower risk early. Warm front may produce some light rain November 4 with milder air moving in. Dry, briefly cooler November 5 before high pressure shifts south of the region with a stronger warm up but still dry weather November 6.

DAYS 11-15 (NOVEMBER 7-11)

Potential rain showers with a cold front November 7, then a shot of dry/cold air November 8-9 before moderating temperatures and still mainly dry later in the period.

Keeping in mind our often-mentioned terrible performances by guidance, there are not a lot of changes in today’s forecast from what was written yesterday, so to summarize, after a very feeble performance by an approaching warm front yesterday, first not giving much rain, and second never making it through, we get into a northerly air flow today which turns easterly on Wednesday as high pressure passes north of the region. A minor disturbance may bring a touch of wet weather later tonight and early Wednesday. And then comes the much-hyped first snow threat of the season! Oh wait a moment, it’s not really much of a snow threat now is it? It’s a rain threat, which we need, and we may score some beneficial rainfall of up to an inch or so mainly from Thursday afternoon through much of Thursday night and into early Friday as low pressure passes south of the region. Some of the moisture from yet another Gulf of Mexico tropical system will be involved in this, but I do think a fair amount of that moisture will miss to the south. Yes, there will be cold enough air from the north getting involved with this system so we probably do see a change to snow in some areas mostly outside of I-95 (though cannot rule out flakes further southeast for a time) as things get ready to wind down on Friday. As for accumulation? No, not 2011. We may see some minor accumulation, possibly measurable, in higher elevations favoring north central MA and southwestern NH, as far as the WHW forecast area goes. By Friday evening, it’s gone, and it’s cold/dry. This sets up a very chilly but dry Halloween on Saturday, which also features the second full moon of the month (Hunter’s Moon).

Details…

TODAY: Lots of clouds, breaks of sun. Highs 52-59. Wind NW to N 5-15 MPH.

TONIGHT: Mostly cloudy. Scattered rain showers late evening and overnight. Lows 38-45. Wind N 5-15 MPH.

WEDNESDAY: Mostly cloudy. A chance of rain showers in the morning. Highs 51-58. Wind NE 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Lows 41-48. Wind E up to 10 MPH.

THURSDAY: Cloudy. Rain likely, especially during the afternoon hours. Highs 46-53. Wind E 5-15 MPH, higher gusts.

THURSDAY NIGHT: Overcast. Periods of rain, may mix with snow southwestern NH and north central MA overnight. Lows 35-42. Wind NE 5-15 MPH.

FRIDAY: Overcast morning with rain except mix/snow likely especially northwest of I-95 with minor accumulation favoring higher elevations of north central MA and southern NH. Partial clearing during the afternoon. Highs 42-49. Wind N 5-15 MPH, higher gusts.

FRIDAY NIGHT: Clearing. Lows 25-32 except 33-40 urban centers. Wind N 5-15 MPH.

SATURDAY: Sunny. Highs 43-50. Wind N 5-15 MPH.

DAYS 6-10 (NOVEMBER 1-5)

Cold start then milder finish November 1 as another cold front approaches. Rain showers night of November 1 to early November 2 may end as snow showers as a shot of cold/wind arrives for the balance of November 2. Another quick-moving disturbance may bring a rain/snow shower early November 3 followed by more breezy and cold weather. Quick warm-up November 4 then cool-down November 5 but high pressure dominates with dry weather.

DAYS 11-15 (NOVEMBER 6-10)

Very divergent medium range guidance (no surprise), so for now going with mainly dry, maybe brief unsettled weather around November 7. A lot of up and down temperatures may occur during this period. Will fine-tune with time.

As low pressure tracks northwest of the region today and tonight, its warm front will try, and fail, to pass through the region. It will produce some wet weather, but not a heavy rainfall, and we’ll never get into the warm sector, having an occluded frontal passage instead, putting us into a northerly air flow Tuesday which then turns more easterly Wednesday as a bubble of high pressure slides north of the region in the wake of the low before it. Another area of low pressure will approach and pass south of the region Thursday, some of this being the moisture remains of Hurricane Zeta from the Gulf of Mexico. A second wave of low pressure will probably become a slightly stronger system as it passes by early Friday. The things to figure out with this have been how heavy the rain will be, and whether or not enough cold air from the north arrives before the precipitation ends to give the region some snow at the end of the system. The answers I believe will be that most of the heavier rain will pass south of the region, but a swath of significant rain is still possible, favoring areas south of I-90 as it stands now, and also that cold air will arrive in time for a mix or brief change to snow for some areas Friday morning but a rather rapid departure of the precipitation will prevent any significant snowfall accumulation from occurring. What is pretty certain is that it will be rather cold on Friday.

Details…

TODAY: Overcast. Periods of light rain and drizzle. Highs 51-58. Wind SE up to 10 MPH.

TONIGHT: Mostly cloudy. Chance of a rain shower. Patchy drizzle early. Lows 44-51. Wind variable up to 10 MPH.

FRIDAY: Overcast morning with rain except mix/snow possible especially northwest of I-95 before ending. Clearing afternoon. Highs 42-49. Wind N 5-15 MPH, higher gusts.

DAYS 6-10 (OCTOBER 31 – NOVEMBER 4)

A Canadian high pressure area brings fair but colder than normal weather for Halloween October 31 before sliding offshore with dry but milder weather November 1. A cold front comes through early November 2 with a rain shower risk then windy/colder air following. Fair, tranquil but chilly November 3 before a rain shower risk with another passing cold front November 4, based on current timing and anticipated error of poorly-performing models.

DAYS 11-15 (NOVEMBER 5-9)

Polar jet stream dominant. Current timing would indicate a warm-up November 5-6 then another cold shot but mainly dry weather.

A reminder: We’re still dealing with guidance that struggles more than would be typical due to deficient data for initialization, and it shows daily. Just yesterday we went from one GFS run showing measurable snow early October 31 in a good portion of southern New England to the next run showing dry/cold weather for the exact same time. It can be a challenge to try to figure out where the model mess-ups are and what they should really be forecasting – a daily struggle, fun at times, frustrating at others. A few adjustments have been made to this forecast but nothing too drastic. As expected, our mild air mass that started the weekend has been replaced by a much cooler one as the air is coming out of eastern Canada via the Maritime Provinces. It’s dry air though, and today will be a chilly late October day, although you will notice the presence of high & mid level cloudiness streaming in from the southwest which will dim and even blot out the sun at times. This is high level moisture in advance of an approaching warm front which, as it approaches the region later tonight and Monday, will cause the clouds to lower and thicken. Such fronts are often known for producing decent overrunning rain, but it appears this one will fail to do that, producing only spotty lighter rainfall at times during Monday. Tuesday, we’ll have a cold front slowly pushing through the region, but the closer we get to this, the more it looks like the front will be starved for moisture, and clouds will be dominant with only limited rain shower activity. High pressure should poke its way into the area for fair weather Wednesday, but the front that goes through on Tuesday will not be far away, and another wave of low pressure is expected to form on the front and may bring another chance of wet weather by Thursday. But there’s plenty of time for this system to fail to materialize as the models currently show. 😉

TODAY: Sun / cloud mix. Highs 50-57. Wind N up to 10 MPH shifting to E.

DAYS 6-10 (OCTOBER 30- NOVEMBER 3)

Model performance renders them basically useless from here onward. Educated guess forecast is that we remain unsettled for a portion of October 30 as the low pressure passes south of the region, but as cold air is moving into the region it will be a race between it and the drier air to see if any of that rain can end as a mix or some snow briefly before we clear out later October 30. Halloween October 31 looks dry and cold. There’s some uncertainty but a disturbance may come by sometime November 1 or 2 with a few rain/snow showers before a reinforcing shot of cold/dry air arrives. Still have to work out the details on that part of the forecast.

DAYS 11-15 (NOVEMBER 4-8)

This period still looks mainly dry with polar jet stream domination. As high pressure sinks to the south of the region we should see a warm-up initially before a cold front brings a new batch of cold air from Canada eventually. Again, timing such details will be impossible this far out, so just that general idea for now.

Discussion…

After 2 recent significant rain events put a small dent in the ongoing drought, we’ve slipped back to old habits of longer stretches without significant rainfall, and despite some upcoming unsettled weather, the overall pattern will continue to support a sustained or even increased drought. But that doesn’t mean every day will be the same. We do have quite a few changes to talk about, most prominently a strong cold front that will make its way eastward across the region today. This front lacks support for much in the way of rain shower activity but otherwise has a sharpness to it, as it will introduce a new air mass in a rather abrupt way. Once it passes a given location, the temperature will waste no time starting to drop. Many locations that make a run at 70 today will find themselves in the 30s by Sunday morning, and the temperature recovery Sunday will be modest as a north to northeast wind feeds additional chilly air in via eastern Canada. Sunday will be a bright fall day through with plenty of sun and just passing clouds during the morning and into the afternoon, a good day for taking a ride to see the last of peak orange/red foliage color wave. We will already see an increase in high and mid level cloudiness later Sunday ahead of some unsettled weather early next week as a warm front moves through Monday and then a cold front moves very slowly across the region Tuesday, producing some episodes of rainfall, though much of it looks on the light side and not very helpful for our drought. High pressure should nose into the region by Wednesday with drier weather.
