Saturday Forecast

2:21AM

DAYS 1-5 (JANUARY 21-25)
Weak high pressure holds over the region today and clouds break apart for some sun and air that is quite mild for late January. A cold front will pass through from north to south early Sunday, returning cloudiness to the region along with colder, more damp air from the Maritimes of Canada. While this is going on, a broad low pressure area will be moving east northeast through the Tennessee Valley, heading for the Northeast. It will elongate slightly and redevelop south of New England during Monday and Monday night, then track north northeastward with the new center passing southeast to east of New England during Tuesday before moving away Wednesday. This system will have a long duration and significant impact on the region with wind and mainly rain, although some snow/sleet/freezing rain will be involved as well for a part of the storm on Monday as the air will be just cold enough. The greatest threat for snow will be outside I-495 and north of the Mass Pike in MA and southwestern NH. This region will also likely see some sleet. Some snow and more likely sleet may mix in as far east as the I-95 belt closer to the Boston/Providence corridor as well during Monday afternoon. The greatest threat for freezing rain would be near Route 2 in north central MA up into southwestern NH when precipitation falls as rain Monday evening. By Tuesday, both surface and aloft should be warm enough for plain rain and it should remain this way from then on.
TODAY: Mostly cloudy morning. Mostly sunny afternoon. Highs 47-54. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Lows 30-38. Wind light W.
SUNDAY: Mostly cloudy. Highs 38-45. Wind shifting to NE 5-15 MPH inland, 10-20 MPH coast, higher gusts South Coast.
MONDAY: Snow/sleet to ice/rain northern and central MA and southern NH, rain/sleet to rain elsewhere. Temperatures steady 32-40. Windy.
TUESDAY: Rain tapering to drizzle. Lows 32-40. Highs 40-48. Windy.
WEDNESDAY: Partly sunny. Lows 28-35. Highs 40-48.

DAYS 6-10 (JANUARY 26-30)
Mild January 26 with a weak system passing north of the region bringing the risk of rain showers. Colder air arrives by January 27 with mainly dry weather or a few snow showers. Still watching for a possible threat of snow or snow showers during the weekend January 28-29. Fair, colder at the end of the period.

DAYS 11-15 (JANUARY 31-FEBRUARY 4)
A more seasonable chill as February arrives. A couple systems may bring the risk of snow showers otherwise mainly dry.

Friday Forecast

3:51PM

DAYS 1-5 (JANUARY 20-24)
One low pressure area will approach from the southwest but fall apart as it runs into high pressure overhead tonight and Saturday. A larger and much stronger storm will come out of the south central US and make a run at New England from late Sunday through Tuesday. There is still some time to work out the details of precipitation types but it looks like the bulk of it will be rain for a large portion of the region, with snow and sleet involved for at least part of the storm for some areas, favoring northern and central MA and southern NH.
REMAINDER OF TODAY: Cloudy. Temperatures steady around 40. Wind light variable.
TONIGHT: Cloudy. Slight chance of light rain southwest of Boston late. Lows 33-40. Wind light variable.
SATURDAY: Mostly cloudy morning. Mostly sunny afternoon. Highs 47-54. Wind W 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 30-38. Wind light W.
SUNDAY: Mostly cloudy. Highs 38-45. Wind NE 5-15 MPH inland, 10-20 MPH coast, higher gusts South Coast.
MONDAY: Snow/sleet to rain northern and central MA and southern NH, rain/sleet to rain elsewhere. Temperatures steady 32-40. Windy.
TUESDAY: Rain tapering to drizzle. Lows 32-40. Highs 40-48. Windy.

DAYS 6-10 (JANUARY 25-29)
A break break January 25 then a weak system passes north of the region with a rain shower risk January 26. Colder air filters in late next week and there will be a potential snow/mix event on the weekend of January 28-29.

DAYS 11-15 (JANUARY 30-FEBRUARY 3)
Fair weather with temperatures a little more seasonably chilly dominating most of this period. Weak systems may bring a few mix/snow showers.

Thursday Forecast

7:20AM

DAYS 1-5 (JANUARY 19-23)
Caution! Watch for ice on any untreated surfaces early to mid morning! This will improve as temperatures warm up by late morning. Low pressure pulls away today and is replaced by a weak ridge of high pressure by Friday into the weekend. This high will largely block an approaching low pressure area Friday night and Saturday which will only be able to send some cloudiness to the region but have most of its precipitation split and sent well north and south of the region. A much larger low pressure area will approach the region late Sunday and Monday, with precipitation likely holding off until Monday. I say precipitation, because even though the current indications are for mostly rain, we may be dealing with some freezing or frozen precipitation for at least a portion of the event over interior locations. Details will be ironed out.
TODAY: Decreasing clouds / increasing sun. Highs 38-45. Wind NW 5-15 MPH.
TONIGHT: Partly cloudy. Lows 22-27 rural and suburban areas, 28-33 urban centers and immediate coast. Wind NW 5-15 MPH.
FRIDAY: Mostly sunny. Highs 38-45 Wind light variable.
SATURDAY: Variably cloudy. Lows 22-30. Highs 40-48.
SUNDAY: Partly cloudy. Lows 18-26. Highs 38-45.
MONDAY: Storm arrives with rain/wind, and the potential for some mix/ice interior areas. Lows 30-38. Highs 38-45.

DAYS 6-10 (JANUARY 24-28)
Large storm system will likely continue to impact the region January 24 with mainly rain. Milder, drier weather January 25 but a chance of rain showers January 26 as low pressure passes north of the region. This may set up a colder and potentially stormy scenario by the very end of the period.

DAYS 11-15 (JANUARY 29-FEBRUARY 2)
Watch early in the period for potential of snow/mix, otherwise mostly dry and colder.

Wednesday Forecast

3:56PM

Apologies for the very late post today.

DAYS 1-5 (JANUARY 18-22)
Elongated low pressure hangs around through tonight then departs Thursday, taking its lingering wet weather with it. Watch for a few icy patches as the temperature will hover near or slightly below freezing especially in areas north and west of Boston through the night. High pressure builds over the region by Friday and tries to hold into the weekend. This will shield the region from one approaching low pressure area that will only manage to send some clouds in Saturday, but the precipitation will never make it. It will also keep the region fair on Sunday, so not a bad weekend overall.
REMAINDER OF AFTERNOON / EVENING: Overcast. Areas of fog. Drizzle likely. Areas of light rain, possible rain/snow mix north of Boston. Temperatures steady 31-36 north and west of Boston, 37-42 Boston south. Wind light E to N.
OVERNIGHT: Cloudy. Patchy fog and drizzle. Chance of a rain/snow shower mainly northeastern MA and southern NH. Temperatures steady 31-36 northwest, 37-42 southeast. Wind light N to NW.
THURSDAY: Decreasing clouds / increasing sun. Highs 38-45. Wind NW 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Lows 22-27 rural and suburban areas, 28-33 urban centers and immediate coast. Wind NW 5-15 MPH.
FRIDAY: Mostly sunny. Highs 38-45 Wind light variable.
SATURDAY: Variably cloudy. Lows 22-30. Highs 40-48.
SUNDAY: Partly cloudy. Lows 18-26. Highs 38-45.

DAYS 6-10 (JANUARY 23-27)
Large storm system approaches from southwest and brings rain later January through January 24, may start with sleet some areas. Improvement briefly January 25 before weaker system passes north of the region January 26 with rain showers, then fair and colder at the end of the period.

DAYS 11-15 (JANUARY 28-FEBRUARY 1)
Watch the January 28-29 weekend for a potential storm that may have snow/mix. Fair and colder weather follows.

Tuesday Forecast

7:33AM

DAYS 1-5 (JANUARY 17-21)
Low pressure approaches from the southwest later today 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. Steadiest precipitation arrives from west to east after 4PM today and lingers through Wednesday morning before tapering off as mainly periods of light rain/drizzle southeast, light mix/snow northwest later Wednesday. Drier weather returns Thursday and Friday, probably Saturday as well as a building high pressure ridge holds off the next approaching low pressure system.
TODAY: Increasing clouds. Highs 33-40. Wind light SE.
TONIGHT: 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 north central MA and southwestern NH. Snow/sleet accumulation of 2-4 inches possible highest elevations north central MA to southwestern NH, coating to 2 inches remainder of interior southern NH to about I-495 northeastern and central MA. Periods of light rain/drizzle afternoon but possibly mixed with snow interior MA and NH. 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.
SATURDAY: Partly cloudy. Lows 18-26. Highs 38-45.

DAYS 6-10 (JANUARY 22-26)
Overall milder temperatures with at least one storm threat, favoring the middle of the period and more likely rain than ice/snow.

DAYS 11-15 (JANUARY 27-31)
Transition toward colder may begin during this period with one weak system favoring light rain/mix early period then another storm threat having a stronger possibility of having mix/snow involved, favoring the second half of the period.

Sunday Forecast

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.

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.

Friday Forecast

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)

Thursday Forecast

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.
