7:36AM

DAYS 1-5 (JANUARY 16-20)
High pressure remains in control today giving a chilly but bright day. Low pressure approaches from the southwest later Tuesday and redevelops over or just south of the region by early Wednesday. Enough cold air will be left in the region for a period of snow/sleet in higher elevations of mainly north central MA and southwestern NH, and sleet/freezing rain in other portions of central into interior northeastern MA and southern NH, with rain closer to the coast and in areas to the south. Timing of the steadiest precipitation will be Tuesday evening through Wednesday morning, after which just periods of lighter rain/drizzle are expected until the system pulls away by the early hours of Thursday. Thursday itself will be a drying day and this dry weather will then continue through Friday as high pressure returns.
TODAY: Sunny. Highs 35-42. Wind light variable.
TONIGHT: Partly cloudy. Lows 18-25 interior valleys, 25-32 elsewhere. Wind light SW.
TUESDAY: Increasing clouds. Highs 33-40. Wind light SE.
TUESDAY NIGHT: Overcast. Snow/sleet/ice central MA and southwestern NH, ice/rain elsewhere with icing most likely central MA and interior northeastern MA and southern NH. Lows 30-38. Wind light E.
WEDNESDAY: Overcast. Rain likely morning with some lingering icing after minor snow accumulation north central MA and southwestern NH. Periods of light rain/drizzle afternoon. Highs 37-44. Wind NE to N 5-15 MPH.
THURSDAY: Partly sunny. Lows 28-35. Highs 38-45.
FRIDAY: Mostly sunny. Lows 20-28. Highs 37-44.

DAYS 6-10 (JANUARY 21-25)
Overall milder temperatures with at least one storm threat, favoring the second half of the period and more likely rain than ice/snow.

DAYS 11-15 (JANUARY 26-30)
Transition toward colder may begin during this period with another storm threat having a stronger possibility of having mix/snow involved, favoring the second half of the period.

2:44AM

DAYS 1-5 (JANUARY 15-19)
High pressure brings fair weather and a seasonable chill today and Monday (MLK Jr Day). Low pressure heads toward New England from the Midwest Tuesday bringing in clouds and eventual wet weather, which will likely linger into if not through Wednesday as the system redevelops nearby. The low exits by Thursday when dry weather returns.
TODAY: Sunny. Highs 35-42. Wind N 5-15 MPH.
TONIGHT: Clear. Lows 13-18 interior valleys, 19-25 elsewhere. Wind light NW.
MONDAY: Sunny. Highs 35-42. Wind W 5-15 MPH.
MONDAY NIGHT: Clear. Lows 15-22 except 23-30 coast. Wind light SW.
TUESDAY: Increasing cloudiness. Chance of rain by mid to late afternoon. Highs 38-45. Wind SE 5-15 MPH.
WEDNESDAY: Cloudy. Rain likely. Lows 35-42. Highs 42-50.
THURSDAY: Partly cloudy. Lows 35-42. Highs 42-50.

DAYS 6-10 (JANUARY 20-24)
High pressure ridging near the East Coast will bring generally dry weather and above normal temperatures for much of this period, but by the end of the period, low pressure approaching from the west will bring a chance of wet weather, most likely rain.

DAYS 11-15 (JANUARY 25-29)
There is some uncertainty as to how the pattern will evolve heading into late January. I believe the trend will be for colder and probably drier, but we may have go to through an additional period of unsettled weather during the transition. Will look at this and try to sort out the details.

2:12AM

DAYS 1-5 (JANUARY 14-18)
I’m a bit under the weather, but I would still like to stay on top of the weather – for you faithful readers! Just a short update today. Weak disturbance passes south of the region tonight with a risk of a little light snow near the South Coast, otherwise high pressure centered north of the region controls the weather through the holiday weekend (including Monday – MLK Jr Day). Low pressure approaches from the west late Tuesday and brings unsettled weather through Wednesday, along with milder air, resulting in a rain event.
TODAY: Sunshine and some clouds. Highs 27-34. Wind N 5-15 MPH early, then light variable.
TONIGHT: Partly cloudy. Slight chance of light snow mainly near the South Coast. Lows 15-22. Wind light variable.
SUNDAY: Mostly sunny. Highs 30-38. Wind N 5-15 MPH.
MONDAY: Mostly sunny. Lows 15-22. Highs 32-40.
TUESDAY: Increasing clouds. Chance of brief ice to rain at night. Lows 18-25. Highs 38-45.
WEDNESDAY: Mainly cloudy. Chance of rain. Lows 32-40. Highs 45-52.

DAYS 6-10 (JANUARY 19-23)
This 5-day period will feature mostly above normal temperatures but periods of unsettled weather as the Pacific jet stream carries several disturbances across the region.

DAYS 11-15 (JANUARY 24-28)
The mild/unsettled pattern starts this period but it may trend colder/drier by the end.

7:22AM

DAYS 1-5 (JANUARY 13-17)
In comes the cold air today which then hangs around for much of the long weekend as high pressure centered north of the region assumes control. A weak disturbance passing south of New England Saturday night will do no more than toss a couple snow flurries into southern areas, though at this point it looks like that activity will miss Foxboro where the Patriots and Texans will be playing. Moderation in temperature will occur late in the period as high pressure become stronger along the East Coast.
TODAY: Mostly sunny to partly cloudy. Slight risk of isolated snow showers late-day especially west and north of Boston. Highs 45-52 early morning, then falling to the 30s. Wind W 10-20 MPH with higher gusts.
TONIGHT: Partly cloudy with isolated snow showers evening. Clear overnight. Lows 15-22. Wind W 10-20 MPH and gusty, shifting to NW.
SATURDAY: Sunshine and some high clouds. Highs 27-34. Wind N 5-15 MPH early, then light variable.
SATURDAY NIGHT: Partly cloudy. Slight chance of snow flurries mainly near the South Coast. Lows 15-22. Wind light variable.
SUNDAY: Mostly sunny. Highs 30-38. Wind N 5-15 MPH.
MONDAY: Mostly sunny. Lows 15-22. Highs 32-40.
TUESDAY: Partly sunny. Lows 18-25. Highs 38-45.

DAYS 6-10 (JANUARY 18-22)
This 5-day period will feature mostly above normal temperatures but periods of unsettled weather as the Pacific jet stream carries several disturbances across the region.

DAYS 11-15 (JANUARY 23-27)
The mild/unsettled pattern starts this period but it may trend colder/drier by the end.

2:35AM

DAYS 1-5 (JANUARY 12-16)
We’ll be in a warm sector today but moisture in the region will produce a few episodes of showers among many clouds, though a few breaks of sun are possible. A strong cold front will come through from northwest to southeast during the overnight and early morning hours Friday, which will be an “upside down” temperature day, with high temperatures in the early part of the day followed by a colder trend. High pressure will build to the north of the region during Saturday with cold air in place, and try to remain through Sunday-Monday, but a disturbance passing to the south of the region Saturday night should be close enough to produce a little light snow at least in CT, RI, and southern MA, which may coincide with the Patriots vs Texans playoff game. If that does occur, it would more likely be just flakes in the air with no significant accumulation.
TODAY: Mainly cloudy but breaks of sun possible. Scattered to numerous rain showers early morning, isolated to scattered rain showers thereafter. Highs 50-55 central MA through southern NH, 55-60 eleswhere. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Mostly cloudy with isolated to scattered rain showers evening. Partly cloudy overnight. Lows 38-45. Wind SW 10-20 MPH, shifting to W.
FRIDAY: Mostly sunny to partly cloudy. Slight risk of isolated snow showers late-day especially west and north of Boston. Highs 45-52 early morning, then falling to the 30s. Wind W 10-20 MPH with higher gusts.
FRIDAY NIGHT: Partly cloudy with isolated snow showers evening. Clear overnight. Lows 15-22. Wind W 10-20 MPH and gusty, shifting to NW.
SATURDAY: Sunshine followed by increasing high clouds. Slight chance of light snow mainly southern MA, CT, and RI at night. Highs 27-34. Wind N 5-15 MPH early, then light variable.
SUNDAY: Mostly sunny. Lows 15-22. Highs 30-38.
MONDAY: Partly sunny. Lows 15-22. Highs 32-40.

DAYS 6-10 (JANUARY 17-21)
This 5-day period will feature mostly above normal temperatures but periods of unsettled weather as the Pacific jet stream carries several disturbances across the region.

DAYS 11-15 (JANUARY 22-26)
The mild/unsettled pattern starts this period but it may trend colder/drier by the end.

4:12AM

DAYS 1-5 (JANUARY 11-15)
Pacific cold front pushes a batch of rain and even embedded thunder in a few areas through from west to east through 7:00AM impacting the early part of the commute today. The remainder of the day will feature sun and passing clouds and mild air. Another batch of lighter rain is possible tonight with a passing disturbance. The mild air will be firmly in control Thursday with rain showers likely over by dawn then holding off again until nighttime with the approach of a cold front. This front will bring colder air gradually into the region on Friday daytime then more aggressively Friday night and Saturday as high pressure builds north of the region. A weak disturbance passing south of the area Saturday night may bring a little light snow to southern areas before fair weather returns for Sunday.
TODAY: Rain and possible thunder ending from west to east through 7AM then sun and passing clouds. Highs 48-55. Wind W 10-20 MPH.
TONIGHT: Mostly cloudy. Chance of light rain. Lows 40-47. Wind SW 5-15 MPH.
THURSDAY: Mostly cloudy. Highs 50-58. Wind SW 10-20 MPH with higher gusts.
THURSDAY NIGHT: Mostly cloudy. Chance of rain showers. Lows 40-47. Wind SW 10-20 MPH with higher gusts.
FRIDAY: Partly cloudy. Highs 47-54 early, then cooling to the 30s by late-day. Wind NW 15-25 MPH with higher gusts.
SATURDAY: Partly sunny day. Mostly cloudy night with a chance of light snow southern areas. Lows 18-25. Highs 28-35.
SUNDAY: Partly cloudy. Lows 11-20. Highs 30-38.

DAYS 6-10 (JANUARY 16-20)
A low pressure will try to run into a ridge along the East Coast and have trouble doing so early to mid period. Another may attempt later in the period. This means any precipitation will likely be limited and fall as rain, otherwise the overall pattern is mild and dry.

DAYS 11-15 (JANUARY 21-25)
Overall mild/dry pattern continues here as well.

1:57AM

DAYS 1-5 (JANUARY 10-14)
Atlantic moisture sneaks in ahead of a warm front today and may bring a few snow/rain showers to eastern MA ahead of the warm front’s precipitation, which will arrive late day and evening probably as rain to the southeast of Boston, a mix to rain in Boston to Providence area, and snow to brief freezing rain to rain to the northwest. After that moves out late evening another ribbon of rain showers will quickly cross the region from west to east along a cold front with a Pacific air mass behind it, so much of the daytime Wednesday will end up dry and fairly mild. Another warm front will pass Thursday morning with a risk of a bit of rain. A stronger cold front will approach late Thursday but not really pass through the region until early Friday. This will allow Thursday and early Friday to continue mild before colder air finally arrives. High pressure from the north will bring dry and colder weather Saturday but by evening or night a disturbance from the west may bring some light snow to parts of the region.
TODAY: Partly sunny to mostly cloudy morning with a few rain/snow showers developing eastern MA from south to north. Mainly cloudy afternoon with a few rain/snow showers possible then a chance of snow/mix southwestern NH and central MA late day. Highs 33-42 from northwest to southeast.
TONIGHT: Cloudy. Mix to brief freezing rain to rain central MA and southwestern NH, mix to rain Boston/Providence corridor, rain elsewhere, ending west to east late evening then frequent rain showers returning west to east overnight. Lows 31-40 early then rising slowly.
WEDNESDAY: Rain showers lingering eastern MA early otherwise partly sunny. Highs 47-54. Wind W 10-20 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Chance of light rain overnight. Lows 38-45. Wind S 5-15 MPH.
THURSDAY: Mostly cloudy. Chance of light rain early. Chance of rain showers northwestern areas late. Highs 50-58. Wind SW 10-20 MPH.
FRIDAY: Mostly cloudy morning with a chance of rain showers. Partly cloudy afternoon. Becoming windy. Lows 42-50. Highs 48-55 morning then turning colder afternoon.
SATURDAY: Sun followed by clouds. Chance of light snow favoring southern areas at night. Lows 18-25. Highs 30-38.

DAYS 6-10 (JANUARY 15-19)
Additional disturbances January 16-18 may produce some periods of precipitation, with type depending on placement of disturbances and areas of high pressure to the north. Temperatures near to above normal.

DAYS 11-15 (JANUARY 20-24)
Continued mild pattern, passing disturbances likely produce rain rather than ice/snow.

1:19AM

DAYS 1-5 (JANUARY 9-13)
Very cold, dry weather starts the week today but we quickly transition out of it during Tuesday as milder air arrives both surface and aloft with lots of clouds and a threat of some light precipitation. A cold front will push through early Wednesday but the air will not get all that cold behind it. In fact it will stay quite mild through Thursday. A stronger cold front is due to arrive sometime on Friday, based on current timing.
TODAY: Sunny morning. Partly sunny afternoon. Highs 18-25. Wind W 5-15 MPH.
TONIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows near 0 coldest spots to near 20 Cape Cod. Wind light S.
TUESDAY: Mostly cloudy. Chance of rain/snow showers Cape Cod and RI morning-midday, eastern MA midday-afternoon. Chance of light snow central MA and southern NH afternoon may mix with or turn to rain. A few rain showers southern and eastern MA, CT, and RI mid to late afternoon. Highs 38-45. Wind SE to S 5-15 MPH.
WEDNESDAY: Variably cloudy. Chance of rain showers in the morning. Lows 35-43. Highs 45-53.
THURSDAY: Mostly cloudy. Chance of rain showers late in the day. Lows 38-45. Highs 45-53.
FRIDAY: Mostly cloudy. Chance of rain showers in the morning. Lows 38-45. Highs 45-53.

DAYS 6-10 (JANUARY 14-18)
High pressure north of the region will bring fair and colder weather Saturday. The middle of the period may see a couple low pressure areas impact the region. Neither look like big storms but both may include at least some frozen precipitation. Dry weather should end the period.

DAYS 11-15 (JANUARY 19-23)
Pattern continues to look fairly mild compared to normal with a few mainly minor storm events, rain favored over ice/snow.

10:32AM

DAYS 1-5 (JANUARY 8-12)
And on we go. The 2 waves of low pressure are now by, with Friday’s relatively mini snow event certainly overtaken by Saturday’s more impressive one, especially if you are located south and southeast of Boston in southeastern MA and in parts of RI, where double-digit snow totals were fairly common. See comments section for more on snowfall amounts. Where do we go from here? Down, then up. At least in terms of temperature. First we have a disturbance and arctic cold front to come through today and this may generate a few snow showers and snow squalls this afternoon and evening. Though I am not expecting them to be widespread, any area that does get one can have briefly heavy snow and very low visibility, and they can quickly coat roads and make them slippery. So if you are traveling this afternoon and early tonight, be on the look-out for this. The temperature then drops way down tonight, with snow cover only aiding the fall. Some interior areas will go sub-zero (F). Monday, recovery will be modest, with many areas struggling to get back to the 20s. The arctic chill will be brief, however, as a warm front approaches Tuesday and high pressure offshore also sends some moisture in from off the Atlantic to the south. This will combine to produce the risk of some light precipitation. Then Wednesday and Thursday, we’ll be in the battle zone between colder air to the north and milder air to the south, with a couple disturbances in the area. It will be hard to time these until we get a little closer, so the forecast below will reflect this in a general sense and will be tweaked as needed.
TODAY: Sunny through midday. Partly cloudy this afternoon with isolated to scattered snow showers by mid afternoon in southern NH and central MA to CT, by late afternoon anywhere. Highs 20-28. Wind W 5-15 MPH with higher gusts late in the day.
TONIGHT: Partly cloudy early with scattered snow showers and snow squalls, then clearing. Lows -5 to 0 interior valleys, 0-5 most areas, 5-12 coastal and urban areas. Wind NW 5-15 MPH gusting over 20 MPH, diminishing overnight.
MONDAY: Sunny morning. Partly sunny afternoon. Highs 18-25. Wind W 5-15 MPH.
MONDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 15-22 early then rising overnight. Wind light S.
TUESDAY: Mostly cloudy. Chance of rain/snow showers Cape Cod and RI morning-midday, eastern MA midday-afternoon. Chance of light snow central MA and southern NH afternoon may mix with or turn to rain. A few rain showers southern and eastern MA, CT, and RI mid to late afternoon. Highs 35-43. Wind SE to S 5-15 MPH.
WEDNESDAY: Variably cloudy. Chance of rain showers. Lows 33-40. Highs 45-53.
THURSDAY: Mostly cloudy. Chance of rain showers. Lows 38-45. Highs 45-53.

DAYS 6-10 (JANUARY 13-17)
A boundary will likely be in the area for much of this period with disturbances moving along it. This is a period of high uncertainty, detail-wise, but for now it appears that it will start out fairly mild with a risk of rain showers and eventually end up colder with a chance of some snow/ice/rain. Not seeing indications of a large storm during this period, but episodes of unsettled weather with the possibility of some significant temperature fluctuations. Will be looking at this period and fine-tuning in future updates.

DAYS 11-15 (JANUARY 18-22)
Indications are for a mild overall regime with occasional unsettled weather taking the form of rain more likely than ice/snow, but again we may be near boundaries fairly frequently so quick changes are possible.

9:47AM

DAYS 1-5 (JANUARY 7-11)
Only minor tweaks to the last update to snowfall amounts, otherwise everything looks about the same as the previous discussion from yesterday afternoon regarding this fairly high impact storm (especially for southeastern MA) today. A quick timeline for snow, which is already falling along the South Coast and the first flakes reaching the South Shore, takes the snow into Boston by late morning then expands it rapidly north and west through the region by midday and through the afternoon. An ending will progress west to east mid to late evening, with Worcester area being out of the snow by around 10PM and Boston by midnight. Snow showers will linger on Cape Cod overnight. Blizzard conditions are likely along the South Shore and across Cape Cod. It’s important to remember that even though these conditions in this storm are predicted for where the heaviest snow totals will be, blizzard conditions are not determined by a snow amount, but rather 3 or more consecutive hours of very low visibility produced by sustained or frequently gusting wind of 35 MPH or greater. The snowfall forecast numbers will be posted below in the detailed forecast and will be similar to those on the previous forecast, but the greatest amounts are still expected over Cape Cod and the South Shore of MA. Once the system pulls away, Sunday will be a day featuring sun and passing clouds. By afternoon and into the evening, some isolated to scattered snow showers are possible as a disturbance and cold front move through from northwest to southeast. This will introduce the coldest air of the stretch for Sunday night, Monday, and Monday night. With a fresh snowcover, it may get especially cold in some areas Monday night and early Tuesday. During the day Tuesday, moderation will be noted. By Wednesday, the next low pressure area moving in from the west will send its center northwest of New England, putting this area on the warm side with the threat of rain showers and temperatures quite mild in comparison to the next few days. On to an updated detailed forecast…
TODAY: Snow spreads from southeast to northwest morning through midday and continues through the afternoon, heaviest over southeastern MA. Blowing snow with blizzard conditions at times Plymouth County of MA through Cape Cod and the Islands. Highs 18-23 southwestern NH and central MA, 22-27 elsewhere 27-32 Cape Cod and Islands. Wind NE to N 5-15 MPH early but increasing to 10-25 MPH inland and 15-35 MPH with higher gusts coastal areas especially south of Boston from the South Shore through Cape Cod and the Islands.
TONIGHT: Overcast with snow gradually ending from west to east then some breaking clouds toward dawn but continued snow showers Cape Cod. Snow accumulations 2-5 inches from Lowell to Worcester to Hartford northwestward including southern NH except the immediate coast, 5-9 inches from Newburyport including the immediate NH Seacoast southwestward to northeastern CT including the upper portion of the I-495 belt, 8-12 inches Cape Ann to Boston to Foxboro to much of RI except possibly heavier outer Cape Ann, 10-18 inches over all of Southeastern MA with localized heavier amounts possible portions of the South Shore of MA to Cape Cod. Lows 15-23. Wind NE to N 10-20 MPH except 15-30 MPH coast.
SUNDAY: Partly sunny. Early morning snow showers possible Cape Cod. Isolated to scattered snow showers anywhere afternoon. Highs 20-28. Wind NW to W 5-15 MPH, shifting to NW late day or evening 15-25 MPH with higher gusts.
MONDAY: Mostly sunny. Lows -5 to +5 interior areas, 5-12 coastal areas. Highs 18-25.
TUESDAY: Partly cloudy. Lows 0-8 interior, 8-15 coast. Highs 33-40.
WEDNESDAY: Mostly cloudy. Rain showers likely. Temperatures rise early morning into 40s. Highs 47-54.

DAYS 6-10 (JANUARY 12-16)
Mild with episodic rain showers January 12-13. January 14 may turn very mild briefly before it cools down for the end of the period.

DAYS 11-15 (JANUARY 17-21)
Fairly mild pattern still expected with a couple precipitation events possible, rain favored over snow.

4:44PM

This is an extra blog post to update the storm for some changes. Much of the information under the updated section is the same as in the previous post. Another post will be made on Saturday morning.

DAYS 1-5 (JANUARY 6-10)
We now have a well-sampled weather system by reliable guidance and can safely detail snow amounts for the upcoming event (wave #2). The first one went by Friday morning and delivered the expected snow in most areas, but a few locations actually received more than expected. This is not highly unusual in a cold situation and with some marginal ocean-enhancement. Some totals of 4 to 7 inches occurred where I had only 1 to 3 inches forecast. This is a difference of a very small amount of melted precipitation, so you can see how being off just slightly can have a big impact on your snow forecast. The same applies to the coming situation. It’s going to be a cold storm with fluff factor and ocean enhancement involved again, but I will do my best to try to get this as accurate as possible. The low pressure wave, larger and stronger than the first, is still going to be a very progressive system so it will be basically about a 12 to 15 hour event starting Saturday morning with the first flakes arriving on Cape Cod via ocean effect snow showers, then the storm’s snow shield spreading north northwestward across the region during the morning and midday before pulling away from west to east during the late evening hours. Ocean effect snow showers may linger on Cape Cod until about dawn on Sunday. The snowfall forecast numbers will be posted below in the details forecast and will be higher than on the previous forecast, but the greatest amounts are still expected over Cape Cod and the South Shore of MA. Once the system pulls away, Sunday will be a day featuring sun and passing clouds. By afternoon and into the evening, some isolated to scattered snow showers are possible as a disturbance and cold front move through from northwest to southeast. This will introduce the coldest air of the stretch for Sunday night, Monday, and Monday night. With a fresh snowcover, it may get especially cold in some areas Monday night and early Tuesday. During the day Tuesday, moderation will be noted. On to an updated detailed forecast…
TONIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 15-23. Wind light NW.
SATURDAY: Overcast. Snow develops on Cape Cod early. Snow develops elsewhere during the morning and midday from southeast to northwest. Heaviest snow is likely from the South Shore just south of Boston through Cape Cod and the Islands during the afternoon. Highs 22-27 except 27-32 Cape Cod and Islands. Wind NE to N 5-15 MPH early but increasing to 10-25 MPH inland and 15-35 MPH and gusty coastal areas.
SATURDAY NIGHT: Overcast with snow gradually ending from west to east then some breaking clouds toward dawn but continued ocean-effect snow showers Cape Cod. Snow accumulations 1-3 inches from Lowell to Worcester to Hartford northwestward, 3-6 inches from Newburyport southwestward to northeastern CT including the upper portion of the I-495 belt, 6-10 inches Cape Ann to Boston to Foxboro to much of RI except possibly heavier outer Cape Ann, 10-18 inches over all of Southeastern MA with localized heavier amounts possible portions of the South Shore of MA to Cape Cod. Lows 15-23. Wind NE to N 10-20 MPH except 15-30 MPH coast.
SUNDAY: Partly sunny. Early morning snow showers likelyCape Cod. Isolated to scattered snow showers anywhere afternoon. Highs 25-32. Wind NW to W 5-15 MPH.
MONDAY: Mostly sunny. Lows -5 to +5 interior areas, 5-12 coastal areas. Highs 18-25.
TUESDAY: Partly cloudy. Lows 0-8 interior, 8-15 coast. Highs 33-40.

DAYS 6-10 (JANUARY 11-15)
Much milder with a few episodes of rain showers January 11-13. Colder, dry January 14. Next threat of precipitation January 15 may include snow but too far away to be certain.

DAYS 11-15 (JANUARY 16-20)
Fairly mild pattern with a couple precipitation events possible, rain favored over snow.

3:36AM

DAYS 1-5 (JANUARY 6-10)
Colder weather has arrived and will last most of this 5-day period. A wave of low pressure will pass southeast of New England today, bringing a period of snow to southeastern MA and RI. Accumulation of snow will be generally minor though enough to shovel and possibly plow mainly over Cape Cod and the Islands. A second wave of low pressure will take a similar path, passing southeast of New England Saturday night. This wave will be larger and a little stronger than the first, and the envelope of snow will likely progress a little further northwest than the first one and be a little heavier as well. Accumulations are again expected to be heaviest over Cape Cod and the Islands but some of this will extend a little further northwest. Some ocean enhancement is possible due to wind off the water over Cape Cod and parts of the South Shore of MA, and possibly outer Cape Ann MA. This exits during the early hours of Sunday although some ocean-effect snow showers may continue into Sunday. During the day on Sunday, a disturbance in the upper atmosphere and a surface cold front will likely cause a round or 2 of snow showers especially in the afternoon. This will introduce the coldest air of the stretch for Sunday night through early Tuesday. But later Tuesday, it will have moderated somewhat, and the dry weather that dominates Monday will continue on Tuesday.
TODAY: Overcast morning with snow of 1-3 inches Cape Cod and Islands, dusting to 1 inch southeastern CT, RI, and southern suburbs of Boston to metro Boston, few flakes or nothing to the northwest. Clearing afternoon. Highs 30-37. Wind N up to 10 MPH.
TONIGHT: Mostly clear evening. Increasing high clouds overnight. Lows 15-23. Wind light NW.
SATURDAY: Thickening overcast morning. Overcast midday and afternoon with snow developing from south to north but probably not reaching south central and southwestern NH as well as north central MA. Highs 26-32. Wind N 5-15 MPH.
SATURDAY NIGHT: Overcast evening with snow of a coating to 1 inch southeastern NH to east central MA eastern CT, 1-3 inches Cape Ann to Boston/Providence, 3-6 inches to the southeast except over 6 inches possible in portions of the South Shore, Cape Cod, and Islands. Partial clearing overnight except lingering snow showers South Shore of MA through Cape Cod. Lows 16-23. Wind NE to N 10-20 MPH.
SUNDAY: Partly sunny. Morning snow showers likely South Shore and Cape Cod. Isolated to scattered snow showers anywhere afternoon. Highs 25-32. Wind N 10-20 MPH morning shifting to W afternoon.
MONDAY: Mostly sunny. Lows 0-10. Highs 18-25.
TUESDAY: Partly cloudy. Lows 5-15. Highs 33-40.

DAYS 6-10 (JANUARY 11-15)
Mild with wet weather January 11. Slightly cooler but still unsettled at times January 12-13. Colder and dry January 14. Possible unsettled weather with rain/snow by the end of the period.

DAYS 11-15 (JANUARY 16-20)
Fairly mild pattern with a couple precipitation events possible, rain favored over snow.

7:34AM

DAYS 1-5 (JANUARY 5-9)
Cold air dominates the next 5 days. There will be a couple snow threats as waves of low pressure pass soth of New England Friday and early Sunday, but favoring southeastern areas, though an additional disturbance from the northwest may produce scattered snow showers all areas Sunday.
TODAY: Mostly sunny. Highs 30-38. Wind W to SW 10-20 MPH with higher gusts.
TONIGHT: Increasing clouds. Lows 18-25. Wind SW diminishing to under 10 MPH.
FRIDAY: Cloudy. A period of snow mainly eastern MA, RI, and southeastern CT, accumulating from nothing or a dusting northwest of Boston to 2-4 inches over Cape Cod and the Islands. Wind light N to NW.
FRIDAY NIGHT: Clearing. Lows 15-22. Wind NW 5-15 MPH.
SATURDAY: Increasing clouds. A period of snow possible southeastern areas at night. Highs 28-35. Wind light N.
SUNDAY: Partly cloudy. Snow showers likely southeastern areas. Chance of snow showers elsewhere. Lows 15-22. Highs 26-33.
MONDAY: Mostly sunny. Lows 0-10. Highs 18-25.

DAYS 6-10 (JANUARY 10-14)
Turning milder. Risk of unsettled weather mainly January 11-13.

DAYS 11-15 (JANUARY 15-19)
Overall mild with a couple precipitation events favoring rain.

7:21AM

DAYS 1-5 (JANUARY 4-8)
We transition to cold but not before a fairly mild day today, although a lot of clouds and a gusty breeze will be around as well. Once a cold front passes this evening with a few rain/snow showers, the cold air comes in and hangs around through the coming weekend. We also continue to eye a couple snow threats from waves of low pressure which will pass south of the region Friday and Sunday.
TODAY: Mostly cloudy with isolated rain showers morning. Partly sunny afternoon. Risk of rain showers mainly west and north of Boston late in the day. Highs 46-54. Wind W 5-15 MPH increasing to 10-20 MPH with higher gusts late in the day.
TONIGHT: Partly cloudy. Scattered rain/snow showers early. Lows 27-35. Wind W 10-20 MPH with higher gusts.
THURSDAY: Partly cloudy. Highs 30-38. Wind W to NW 10-20 MPH with higher gusts.
FRIDAY: Mostly cloudy. Chance of light snow, favoring southern and eastern MA, CT, and RI. Lows 16-23. Highs 28-35.

2:41AM

DAYS 1-5 (JANUARY 3-7)
An initial disturbance passing south of New England this morning and early afternoon will bring spotty light drizzle/rain, some of which may freeze on surfaces northwest of I-495 this morning. During this time, a stronger low pressure area will be moving rapidly northeastward through the Mid Atlantic States and will send areas of moderate to heavy rain through southern New England late this afternoon and early tonight. This low will move beyond the region overnight and early Wednesday but it will remain fairly mild until a cold front arrives later in the day Wednesday with one or two rounds of passing showers of rain and snow, rain favoring most areas with any initial shower and snow more possible in areas north and west of Boston if there is a second area as the colder air comes in. Thursday will be a fair but colder day. A wave of low pressure will pass south of the region Friday but may be close enough to bring some light snow to parts of the region, especially southern and eastern MA, CT, and RI. Fair weather should return Saturday behind this system.
TODAY: Overcast. Areas of fog. Scattered light rain/drizzle morning and early afternoon, some freezing on surfaces far northwest of Boston this morning, then more widespread rain which may be heavy at times late-day. Highs 37-45 northwest of Boston, 45-53 Boston southeastward. Wind E up to 10 MPH morning, E to SE 5-15 MPH with higher gusts afternoon.
TONIGHT: Cloudy. Rain, heavy at times early, tapering off to spotty light rain and drizzle after. Patchy fog. Temperatures generally steady. Wind variable 5-15 MPH, higher gusts.
WEDNESDAY: Mostly cloudy with isolated rain showers morning. Partly sunny afternoon. Risk of rain showers mainly west and north of Boston late in the day. Highs 46-54. Wind W 5-15 MPH increasing to 10-20 MPH with higher gusts late in the day.
WEDNESDAY NIGHT: Partly cloudy. Scattered rain/snow showers early. Lows 27-35. Wind W 10-20 MPH with higher gusts.
THURSDAY: Partly cloudy. Highs 30-38. Wind W to NW 10-20 MPH with higher gusts.
FRIDAY: Mostly cloudy. Chance of light snow, favoring southern and eastern MA, CT, and RI. Lows 16-23. Highs 28-35.
SATURDAY: Partly sunny. Lows 12-20. Highs 27-34.

DAYS 6-10 (JANUARY 8-12)
Wave of low pressure should remain offshore and a cold northerly flow may bring a few snow showers January 8 but cannot rule out low pressure to the south passing closer so will watch. Fair and chilly January 9-10. Milder January 11-12 with possible unsettled weather.

DAYS 11-15 (JANUARY 13-17)
Milder pattern with a few episodes of brief unsettled weather with rain showers favored.
