Sunday Forecast

2:46AM

DAYS 1-5 (JANUARY 31-FEBRUARY 4)…
A mild southwesterly air flow will dominate today into Monday as January turns to February. A cold front may set off a few rain showers later Monday and will knock the temperature down only slightly for Tuesday, which will be a fair weather day as a sliver of high pressure slides across the Northeast. Warmer air will move in during Wednesday but may take a while to reach the entire area as we’ll need to get that front back through as a warm front. Finally a warm surge will flood the entire region but will be accompanied by wet weather as numerous rain showers line up along and ahead of a cold front. This front will pass through the region from west to east late Wednesday, bringing drier and cooler weather back by Thursday.
TODAY: Partly sunny. Highs 47-54. Wind SW 5-15 MPH with higher gusts.
TONIGHT: Mostly cloudy. Lows 33-40. Wind SW 5-15 MPH with higher gusts.
MONDAY: Variably cloudy. Chance of rain showers in the afternoon. Highs 48-55.
TUESDAY: Mostly sunny. Lows in the 30s. Highs in the 40s.
WEDNESDAY: Mostly cloudy. Rain showers likely. Lows in the 40s. Highs in the 50s.
THURSDAY: Partly cloudy. Lows in the 30s. Highs in the 40s.

DAYS 6-10 (FEBRUARY 5-9)…
An offshore low pressure area should stay far enough out to sea to leave the region dry February 5. Unsettled weather develops over the weekend of February 6-7, but is more likely during February 7. Rain or snow is possible. February 8 turns dry but likely windy as a bigger storm evolves over the ocean. Fair weather and somewhat colder by February 9.

DAYS 11-15 (FEBRUARY 10-14)…
The next storm threat looms for early in the period but there may be a lack of cold to work with and odds may favor mix/rain versus snow. Another stretch of unsettled weather is possible later February 12 through the end of the period.

Saturday Forecast

9:12AM

DAYS 1-5 (JANUARY 30-FEBRUARY 3)…
Warm front moves through today producing some cloudiness, then in and out of clouds as mild air becomes established on Sunday. Not a bad weekend at all by January standards. Some changes for the first few days of February with a mild Monday, a cold front producing a few rain showers Monday evening but only slightly cooler air for Tuesday before a bigger warm-up for Wednesday, though accompanied by a wet weather as a stronger cold front approaches.
TODAY: Mostly sunny morning. Mostly cloudy afternoon. Highs 37-44. Wind S 5-15 MPH.
TONIGHT: Mostly cloudy. Lows 30-37. Wind SW 5-15 MPH with higher gusts.
SUNDAY: Partly sunny. Highs 47-54. Wind SW 5-15 MPH with higher gusts.
MONDAY: Partly cloudy. Chance of rain showers evening. Lows in the 30s. Highs in the 50s.
TUESDAY: Mostly sunny. Lows in the 30s. Highs in the 40s.
WEDNESDAY: Mostly cloudy. Rain showers likely. Lows in the 40s. Highs in the 50s.

DAYS 6-10 (FEBRUARY 4-8)…
Fair weather expected February 4-5. Unsettled with chance of snow/mix February 6-7. Fair February 8. Temperatures near to above normal overall.

DAYS 11-15 (FEBRUARY 9-13)…
A passing system may bring precipitation about February 10. Storm threat again at the end of the period. Temperatures fairly close to normal though variable.

Friday Forecast

2:51AM

DAYS 1-5 (JANUARY 29-FEBRUARY 2)…
Unsettled weather today but only minor event with rain and snow showers as an offshore low pressure area deepens and accelerates away to the northeast, toward Nova Scotia, while a weakening system coming out of the Great Lakes transfers its energy to the offshore system. The very progressive pattern then brings briefly cooler northwesterly wind in by Friday night, followed by a warm front bringing more cloudiness on Saturday, but leading to a spell of very mild weather as January ends and February arrives Sunday and Monday. A cold front will approach by late Monday but will set off only a few rain showers Monday night or early Tuesday with only a slight cool-down for Tuesday.
TODAY: Mostly cloudy. Scattered rain and snow showers. Highs 35-42. Wind light variable becoming NW and increasing to 5-15 MPH.
TONIGHT: Partly cloudy evening. Clearing overnight. Lows in the 20s. Wind NW 10-20 MPH and gusty.
SATURDAY: Increasing clouds. Highs 35-42. Wind W 5-15 MPH shifting to SW.
SATURDAY NIGHT: Mostly cloudy evening. Partly cloudy overnight. Lows 28-35 early then rising overnight. Wind SW 5-15 MPH.
SUNDAY: Partly sunny. Highs 48-55. Wind SW 10-20 MPH.
MONDAY: Partly cloudy. Risk of evening rain showers. Lows in the 30s. Highs in the 50s.
TUESDAY: Partly cloudy. Lows in the 30s. Highs in the 40s.

DAYS 6-10 (FEBRUARY 3-7)…
Potential record-challenging warmth with rain showers February 3. Colder with rain or snow showers possible February 4. Fair and cool February 5. A weak system may bring rain/snow showers by February 6 or 7.

DAYS 11-15 (FEBRUARY 8-12)…
Trending colder. Risk of rain/snow showers early in the period then mostly dry weather.

Thursday Forecast

7:34AM

DAYS 1-5 (JANUARY 28-FEBRUARY 1)…
High pressure brings fair weather today. A pair of low pressure systems will pass by on their northeastward stroll across the atmospheric dance floor on Friday, one to our northwest, one to our southeast, attempting to join hands in the start of a ballroom tango, but before they can launch into their first spin together they will be beyond the area, leaving us with minimal impact, i.e., a little rain and snow activity. Fair weather returns for the weekend as well as Monday along with a warm-up as the jet stream lifts to the north and high pressure builds to the south.
TODAY: Mostly sunny. Highs 35-42. Wind light SW.
TONIGHT: Clouding up. Lows 25-32. Wind light S.
FRIDAY: Mostly cloudy. A period of rain Cape Cod. A few rain/snow showers elsewhere. Highs 35-42. Wind variable 5-15 MPH shifting to NW and increasing to 10-20 MPH late.
SATURDAY: Partly cloudy. Lows 15-25. Highs in the 30s.
SUNDAY: Mostly cloudy. Lows in the 20s. Highs in the 40s.
MONDAY: Partly sunny. Lows in the 30s. Highs in the 50s.

DAYS 6-10 (FEBRUARY 2-6)…
A weak cold front passes early February 2 with a few rain showers then fair weather. A warm front/cold front combo passes through February 3 as a stronger storm passes through the Great Lakes into southeastern Canada and will likely bring widespread rain showers as it is quite mild. Mostly fair weather and a colder trend sets up February 4-6, though a few snow showers may occur at times.

DAYS 11-15 (FEBRUARY 7-11)…
Briefly moderating then possibly turning much colder later in the period with a few snow showers.

Wednesday Forecast

7:34AM

DAYS 1-5 (JANUARY 27-31)…
Cloudiness gradually exits today as a front slogs eastward offshore. Two low pressure systems, one in the polar jet stream passing through the Great Lakes and another with the subtropical jet stream passing south of New England Thursday night, will remain separate until beyond the region Friday. This will prevent a significant storm and just result in the risk of a bit of snow and rain shower activity. A weak area of high pressure will bring fair weather Saturday and a weak low pressure area will be in the region Sunday with more cloudiness.
TODAY: Lots of clouds to start, then increasing sunshine. Highs 36-43. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 18-25. Wind light W.
THURSDAY: Mostly sunny. Highs 35-42. Wind light SW.
FRIDAY: Mostly to partly cloudy and windy. Risk of snow showers early and snow or rain showers midday. Lows in the 20s. Highs in the 30s.
SATURDAY: Partly cloudy. Lows 15-25. Highs in the 30s.
SUNDAY: Mostly cloudy. Lows in the 20s. Highs in the 40s.

DAYS 6-10 (FEBRUARY 1-5)…
Disturbance coming through the region February 1 will produce a few rain showers with mild air. Continued above normal temperatures February 2-3 with fair weather February 2 and a few rain showers February 3. Fair and colder February 4-5.

DAYS 11-15 (FEBRUARY 6-10)…
Fair with moderating temperatures early in the period. A northern stream storm system will bring unsettled weather mid to late period followed by a possible blast of colder air.

Tuesday Forecast

7:22AM

DAYS 1-5 (JANUARY 26-30)…
Weak low pressure will pass well north of southern New England today and tonight. Its trailing cold front will pass this evening then slow down offshore Wednesday. This system will bring some cloudiness today into Wednesday but no more than a passing rain shower this evening. A pair of systems, one in the polar jet stream passing through the Great Lakes and another with the subtropical jet stream passing south of New England Thursday night, are expected to stay separated and not really interact until beyond the region Friday. This will prevent a significant storm and just result in the risk of a bit of snow shower activity. A weak area of high pressure will bring fair weather Saturday.
TUESDAY: Variably cloudy. A late-day rain shower possible mainly northwest of Boston. Highs 43-50. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Variably cloudy. An evening rain shower possible. Lows 33-40. Wind SW to W 5-15 MPH and gusty.
WEDNESDAY: Lots of clouds to start, then increasing sunshine. Highs 36-43. Wind W 5-15 MPH.
THURSDAY: Sunshine during the day. Clouds moving in with a risk of snow showers overnight. Lows 18-25. Highs in the 30s.
FRIDAY: Mostly to partly cloudy and windy. Risk of snow showers early. Lows in the 20s. Highs in the 30s.
SATURDAY: Partly cloudy. Lows 15-25. Highs in the 30s.

DAYS 6-10 (JANUARY 31-FEBRUARY 4)…
A few periods of unsettled weather, more cloudiness than significant precipitation events, January 31 through February 3, though with variable temperatures will have to watch for possible mix/frozen precipitation at some point. Should turn dry and colder at the end of the period.

DAYS 11-15 (FEBRUARY 5-9)…
An overall fairly quiet pattern with variable temperatures.

Monday Forecast

7:28AM

DAYS 1-5 (JANUARY 25-29)…
High pressure brings fair weather today. Weak low passes to north late Tuesday and its cold front will slow down offshore Wednesday. Low pressure moves up along this front later in the week. Right now think this week be a close call but stay mostly offshore.
TODAY: Mostly sunny. Clouds from the west late. Highs in the 30s. Wind light W.
TONIGHT: Variably cloudy. Lows 25-32. Wind light W.
TUESDAY: Mostly cloudy. Spotty light freezing rain/drizzle southern NH and northern MA early. Scattered rain showers afternoon. Highs in the 40s.
WEDNESDAY: Partly sunny. Lows 25-32. Highs 35-42.
THURSDAY: Mostly cloudy. Risk of mix/snow southeastern MA late. Lows 18-25. Highs in the 30s.
FRIDAY: Mostly to partly cloudy and windy. Temperatures steady in 30s.

DAYS 6-10 (JANUARY 30-FEBRUARY 3)…
Fair January 30. Periods of unsettled
weather possible to end January and start February as a frontal system may be nearby with mild air trying to push up from the south while a cold high builds across eastern Canada.

DAYS 11-15 (FEBRUARY 4-8)…
Weak weather systems possible around February 4 and 6 otherwise a generally quiet weather pattern expected during this period with temperatures near to above normal.

Sunday Forecast

8:17AM

DAYS 1-5 (JANUARY 24-28)…
Looking back: The storm did MOSTLY as expected, but I was too low on my snow numbers for the immediate North Shore through Boston and its immediate outskirts, as well as my own area in the northwest suburbs. A pair of persistent snow bands in these locations while the snow shield was quasi-stationary on the storm’s pivot added more snow than I had forecast.
All that remains: Other than any snow cleanup, what lingers today is one more round of coastal flooding at this morning’s high tide in areas prone to it.
Looking ahead: A much quieter week of weather is ahead with fair and chilly weather today and Monday though a weak disturbance will bring some clouds across the region tonight. Milder air dominates Tuesday but with cloudiness and a risk of a spotty patch or 2 of freezing rain/drizzle mainly northern MA and southern NH first thing in the morning as a warm front passes – not a widespread and dangerous situation, then a chance of rain showers ahead of a cold front later on. Fair and cool for midweek.
TODAY: Mostly sunny. Clouds from the west late. Highs in the 30s. Wind N 5-15 MPH.
TONIGHT: Variably cloudy. Lows in the 20s. Wind light W.
MONDAY: Partly cloudy. Highs in the 30s. Wind light W.
TUESDAY: Mostly cloudy. Spotty light freezing rain/drizzle southern NH and northern MA early. Scattered rain showers afternoon. Lows 25-32. Highs in the 40s.
WEDNESDAY: Partly sunny. Lows 25-32. Highs 35-42.
THURSDAY: Partly cloudy. Lows 18-25. Highs in the 30s.

DAYS 6-10 (JANUARY 29-FEBRUARY 2)…
Periods of cloudiness and remote risk of light precipitation January 29-30 as systems pass by in a split flow (one passing to the south with the subtropical jet stream and one to the north with the polar jet stream). Fair January 31. Another period of unsettled weather possible to start February as a frontal system may be nearby with mild air trying to push up from the south while a cold high builds across eastern Canada.

DAYS 11-15 (FEBRUARY 3-7)…
Weak weather systems possible around February 4 and 6 otherwise a generally quiet weather pattern expected during this period with temperatures near to above normal.

Saturday Forecast Update

7:44PM

Here is an extra post to get things updated. Much of what comes below will be unchanged from the previous post, but some tweaks are being made to the final snow numbers and a couple other minor adjustments. An additional update will follow tomorrow morning as usual.

DAYS 1-5 (JANUARY 23-27)…
Storm update! What to expect in southern New England…
WHEN: Ongoing but ending Sunday morning.
SNOW START TIME: It started a long time ago and wherever it didn’t snow, it’s not gonna snow.
SNOW END TIME: From northwest to southeast through about 3AM Sunday, lastly Cape Cod and Nantucket.
SNOW INTENSITY: Heaviest bands as of 7:25PM are across Cape Cod and the South Coast with another in the immediate Boston area to Metro West but these will be shifting south to southeast and diminishing.
SNOW ACCUMULATION: Nothing or flakes in the air briefly in southern NH, dusting to 1 inch north central and northeastern MA, 1-3 inches just northwest of Boston stretching northeast to interior northeastern MA from near Boston west southwestward along the Mass Pike belt and just to the north, 3-6 inches from Boston west southwestward just south of the Mass Pike, 6-12 inches to the south of there with locally over 12 inches in some locations near the South Coast.
WIND: Gusts of 30 MPH or greater are likely in coastal NH and northeastern MA, 40 MPH or greater from coastal areas near Boston to the South Shore, 50 MPH or greater Cape Cod across to coastal RI and down Martha’s Vineyard, and 60 MPH or greater on Nantucket. Most of this has already occurred but the threat lingers a little longer this evening.
POWER OUTAGES: The most likely area for any power problems will remain the southern part of Cape Cod where the combination of strongest wind and wettest snow will be. Scattered outages elsewhere in southeastern MA, RI, and CT.
COASTAL FLOODING: Minor to moderate coastal flooding is most likely in the prone areas such as Scituate and Sandwich and similar locations from the South Shore of MA through Cape Cod and the from a couple hours before to a couple hours after high tide times both Saturday night and Sunday morning. Cannot rule out a pocket of major flooding since we have a full moon and astronomical high tides at this time. Major flooding would not be widespread in coastal areas.
After the storm! What to expect…
Improvement Sunday, fair and milder Monday, windy and not too chilly but a few rain showers Tuesday with an approaching cold front, then breezy and colder but fair weather Wednesday behind this front.
TONIGHT: Snow retreats northwest to southeast, lastly on Cape Cod. See above for accumulations. Lows 23-30. Wind NE to N 15-30 MPH, higher gusts (see above).
SUNDAY: Lingering clouds Cape Cod for part of the morning otherwise mostly sunny. Highs in the 30s. Wind NW 10-20 MPH with higher gusts.
MONDAY: Partly cloudy. Lows 18-25. Highs 35-42.
TUESDAY: Mostly cloudy and windy. Brief light mix possible morning. Few rain showers late. Lows 28-35. Highs in the 40s.
WEDNESDAY: Partly cloudy and windy. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (JANUARY 28-FEBRUARY 1)…
Watching from late January 28 into January 30 for possible unsettled weather but odds favor most activity missing both to the north and south or just a fairly minor system passing through. Fair weather for the end of the period. Temperatures near to above normal.

DAYS 11-15 (FEBRUARY 2-6)…
Unsettled weather possible February 2-4 with an air mass battle possibly setting up in the area. Fair and a little colder by February 5-6 based on current timing.

Saturday Forecast

8:56AM

DAYS 1-5 (JANUARY 23-27)…
Storm update! What to expect in southern New England…
WHEN: Today and tonight (except Sunday morning as well regarding tide impact).
SNOW START TIME: Already underway southwestern CT, remainder of South Coast of CT to Cape Cod mid to late morning, however by late morning a few snow showers unrelated to the storm are possible from near Boston to the North Shore and northwest Suburbs, otherwise the storm-related snow should reach northeastern CT, northern RI, and south central MA during the early afternoon and its furthest extend northward into MA to near the NH border during mid to late afternoon.
SNOW END TIME: From northwest to southeast generally between 8PM and 3AM, that is, firstly in the areas it reached the latest, and lastly around Cape Cod and the Islands closer to 3AM. This means areas near the South Coast snow the longest while areas northwest of Boston snow lesser time.
SNOW INTENSITY: Moderate snow as a general rule across most areas from Boston along the Mass Pike and southward, but a band of heavier snow will push into the South Coast of MA, RI, and CT. Light to very light snow as you head north and northwest toward the MA/NH border.
SNOW ACCUMULATION: Nothing or flakes in the air briefly in southern NH, dusting to 1 inch north central and northeastern MA, 1-3 inches from near Boston west southwestward along the Mass Pike belt and just to the north, 3-6 inches from just south of Boston down into much of southeastern MA to northern RI and northeastern CT, 6-10 inches southeastern CT and southern RI and the immediate South Coast of MA including the southern part of Cape Cod and the island of Martha’s Vineyard. Exceptions will be southwestern CT where over 10 inches will fall, Nantucket where an intense snow band may result in over 12 inches, and the eastern part of Cape Cod where slightly lighter precipitation and a possible mix may limit snow to 2-4 inches there.
WIND: Gusts of 30 MPH or greater are likely in coastal NH and northeastern MA, 40 MPH or greater from coastal areas near Boston to the South Shore, 50 MPH or greater Cape Cod across to coastal RI and down Martha’s Vineyard, and 60 MPH or greater on Nantucket.
POWER OUTAGES: The most likely area for any power problems will be the southern part of Cape Cod where the combination of strongest wind and wettest snow will be. Isolated outages possible elsewhere.
COASTAL FLOODING: Minor to moderate coastal flooding is most likely in the prone areas such as Scituate and Sandwich and similar locations from the South Shore of MA through Cape Cod and the from a couple hours before to a couple hours after high tide times both Saturday night and Sunday morning. Cannot rule out a pocket of major flooding since we have a full moon and astronomical high tides at this time. Major flooding would not be widespread in coastal areas.
After the storm! What to expect…
Improvement Sunday, fair and milder Monday, windy and not too chilly but a few rain showers Tuesday with an approaching cold front, then breezy and colder but fair weather Wednesday behind this front.
TODAY: Overcast. A band of light snow showers possible late morning to early afternoon from Boston area to the 128/95 belt around the city then may progress westward before dissipating, otherwise snow developing from south to north during the course of the day. Snow may mix with or even turn to rain at times on parts of Cape Cod and Nantucket. Highs 27-35, coldest over interior MA and southwestern to south central NH, mildest Cape Cod. Wind N to NE 5-15 MPH in areas northwest of Boston, NE to E 10-25 MPH with higher gusts elsewhere (see above for peak gusts).
TONIGHT: Snow retreats northwest to southeast, lastly on Cape Cod. See above for accumulations. Lows 23-30. Wind NE to N 15-30 MPH, higher gusts (see above).
SUNDAY: Lingering clouds Cape Cod for part of the morning otherwise mostly sunny. Highs in the 30s. Wind NW 10-20 MPH with higher gusts.
MONDAY: Partly cloudy. Lows 18-25. Highs 35-42.
TUESDAY: Mostly cloudy and windy. Brief light mix possible morning. Few rain showers late. Lows 28-35. Highs in the 40s.
WEDNESDAY: Partly cloudy and windy. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (JANUARY 28-FEBRUARY 1)…
Fair weather is expected for most of if not all of this period but we may be in between systems in both the northern and southern jet streams January 29-30 so will have to keep an eye on these for most likely minor impact with any shift in storm tracks. Temperatures near to above normal.

DAYS 11-15 (FEBRUARY 2-6)…
Unsettled weather possible February 2-4 with an air mass battle possibly setting up in the area. Fair and a little colder by February 5-6 based on current timing.
