7:31AM

DAYS 1-5 (JANUARY 11-15)…
Changing weather the next few days as wind/cold/dry today is followed by a clipper system and unsettled weather later Tuesday, then another windy/cold Wednesday and a more tranquil Thursday and Friday with a cold Thursday and slightly milder Friday.
TODAY: Sunshine and a few passing clouds. Highs in the 30s. Wind W 15-25 MPH gusting over 30 MPH.
TONIGHT: Mostly clear. Lows 15-20 except 20-25 Cape Cod and Islands as well as urban centers. Wind W diminishing to 5-15 MPH.
TUESDAY: Clouding over. Precipitation arriving late day into evening as mix to snow northwest of Boston, rain to mix ending as snow Boston southeast. Snow accumulation of up to 1 inch possible northwest of Boston with an isolated heavier amount possible in north central MA and southwestern NH, but generally trace amounts to coatings elsewhere. Highs in the 30s. Wind SW to S 5-15 MPH with higher gusts.
WEDNESDAY: Partly cloudy and windy. Isolated snow showers. Lows in the 10s. Highs around 30.
THURSDAY: Mostly sunny. Lows in the 10s. Highs around 30.
FRIDAY: Mostly sunny. Lows in the 20s. Highs around 40.

DAYS 6-10 (JANUARY 16-20)…
Unsettled weather possible during the weekend of January 16-17 with timing not certain and precipitation type also somewhat uncertain, but favoring rain versus snow based on the thought that systems will remain fairly weak and we won’t see a merger of the polar and subtropical jet streams. Dry and colder January 18-20.

DAYS 11-15 (JANUARY 21-25)…
Dry and milder early in the period. Watch for a storm threat later in the period.

7:37AM

DAYS 1-5 (JANUARY 10-14)…
A stormy Sunday! Strong low pressure tracks well northwest of the region today and tonight but a tight wind gradient means strong wind and plenty of moisture and mild air coming up with the system means some heavy rain. The strongest wind gusts from the southeast today will occur over Cape Cod, Nantucket, and east and south facing shores of the remainder of southeastern New England. Once the cold front of this system pulls through during this evening, the rain will shut off and the wind will shift. Colder air will flow in quickly but a gusty wind, having shifted to the west, will dry out much of the ground before the rainwater on it can freeze, other than in areas where there are deeper puddles, so by morning watch for some ice patches. The daytime of Monday will be fair, windy, and cold. A clipper system from Canada arrives via the Great Lakes later Tuesday then redevelops in the Gulf of Maine Tuesday night and early Wednesday. This system will bring some snow or snow showers to the region with minor accumulation at best before exiting and reinforcing the cold for midweek.
TODAY: Overcast. Periods of rain into late morning then widespread rain, heavy at times, and embedded thunderstorms midday on. Highs 48-55, may reach the upper 50s in parts of southeastern and eastern MA. Wind SE increasing to 10-20 MPH with gusts 30-50 MPH inland and 20-30 MPH with gusts 40-60 MPH coast. Strongest winds late in the day.
TONIGHT: Rain ends west to east early, a few rain showers may linger briefly, otherwise clearing. Lows 25-32. Wind shifting to W 15-30 MPH with higher gusts.
MONDAY: Mostly sunny to partly cloudy. Highs in the 30s. Wind W 15-30 MPH with higher gusts.
TUESDAY: Increasing clouds. Chance of snow or snow showers late day and night. Lows 15-22. Highs 25-32.
WEDNESDAY: Mostly cloudy with snow showers early, then partly sunny. Lows 20-27. Highs 28-35.
THURSDAY: Mostly sunny. Lows in the 10s. Highs in the 20s.

DAYS 6-10 (JANUARY 15-19)…
Fair and cold January 15-16. Storm threat for later January 17 into January 18 looks minor at this time as it appears systems in the northern and southern jet streams will not interact completely until they pass by, but will watch closely. Fair and cold January 19.

DAYS 11-15 (JANUARY 20-24)…
Fair and milder January 20-22, colder January 23. Watch for the next storm threat late in the period.

9:03AM

DAYS 1-5 (JANUARY 9-13)…
Onshore flow at low levels as weakening system above it passes by today, meaning damp and grey, though some inland areas are cold enough to support a little very light frozen precipitation this morning. Stronger storm passes through the Great Lakes and up the St. Lawrence Valley Sunday and Sunday night, and for this area that means a period of moderate to heavy rain, mild air, and strong, gusty wind. Windy/colder/drier behind this system Monday. Next disturbance may bring some snow showers late Tuesday and early Wednesday, but will be progressive enough that when it redevelops into a strong storm offshore Wednesday, it will be too far away to deliver meaningful snow.
TODAY: Cloudy. An area of light rain/mix north and west of Boston for a while in the morning, otherwise patchy drizzle. Highs 38-45. Wind E up to 10 MPH.
TONIGHT: Cloudy. Areas of drizzle. Temperatures steady 38-45. Wind light SE.
SUNDAY: Cloudy. Rain and embedded thunderstorms developing west to east morning, ending west to east late day. Highs 48-55, coolest valleys of southern NH and north central MA. Wind SE to S increasing to 15-25 MPH with gusts over 30 MPH common and gusts over 40 MPH possible.
MONDAY: Sun/clouds. Windy. Lows in the 20s. Highs in the 30s.
TUESDAY: Increasing clouds. Possible snow showers at night. Lows in the 10s. Highs in the 20s.
WEDNESDAY: Variably cloudy. Possible snow showers early. Lows in the 10s. Highs in the 20s.

DAYS 6-10 (JANUARY 14-18)…
Dry and cold January 14-16. Storm threat later January 17 into January 18 but far too early for detail. General pattern favors this system being too far south for major impact but will keep an eye on it.

DAYS 11-15 (JANUARY 19-23)…
Pattern turns fairly quiet with seasonable to mild temperatures dominant.

10:39AM

Watch for risk of rain or snow around the middle of the period, otherwise mainly dry weather with variable temperatures.

7:27AM

DAYS 1-5 (JANUARY 6-10)…
No significant changes. High pressure in control keeps it dry with moderating temperatures the next few days. A weakening disturbance passes by early Saturday and then a stronger low tracks northwest of the region Sunday, making the weekend more unsettled.

DAYS 11-15 (JANUARY 16-20)…
Watch for risk of rain or snow around the middle of the period, otherwise mainly dry weather with variable temperatures.

7:28AM

DAYS 1-5 (JANUARY 5-9)…
Arctic chill today, and this time there WILL be sunshine in most of the region, although some ocean-effect snow showers will continue over Cape Cod and the Islands, gradually diminishing. High pressure that builds across the region for one more very cold night tonight then slips offshore with fair weather and not as cold for midweek. Wednesday nights low temperatures will be similar to today’s high temperatures, giving you an idea of the moderation upcoming, which will continue into late week, and set the stage for the first of 2 disturbances coming, the first of which will pass through from the southwest early Saturday with light mix/rain.
TODAY: Clouds and snow showers Cape Cod / Islands with some additional light snow accumulation likely. Mostly sunny elsewhere. Highs 20-27. Wind N 10-20 MPH, higher gusts possible.

THURSDAY: Mostly sunny. Highs 40-47. Wind SW 10-20 MPH.
FRIDAY: Increasing clouds. Late night mix possible. Lows in the 20s. Highs in the 40s.
SATURDAY: Cloudy with light mix/rain possible morning. Partial clearing afternoon. Lows in the 30s. Highs in the 40s.

DAYS 6-10 (JANUARY 10-14)…
Second of two disturbances brings a chance of rain later January 10 as mild air dominates. Windy, cooler, drier January 11. A system from the southwest brings a chance of light precipitation late on January 12 to early January 13 followed by drier and colder later January 13 through January 14.

DAYS 11-15 (JANUARY 15-19)…
Mainly dry weather. Looks like only weak systems may bring scattered rain/snow showers while more important storms miss to the south as a split jet stream flow dominates and the streams stay separated. Temperatures variable, averaging near to slightly above normal.

7:13AM

DAYS 1-5 (JANUARY 4-8)…
Arctic air and Cape Cod / Nantucket ocean-effect snow showers start out the week today, and the cold continues Tuesday as the snow showers end. High pressure moves overhead with moderating temperatures midweek and then by the end of the week one low goes out far south of us while a second system approaches from the southwest.
TODAY: Variably cloudy east coastal MA with snow showers possible Cape Ann and snow showers likely from the South Shore through Cape Cod and Nantucket with accumulations of a coating to 2 inches except locally up to 5 inches outer Cape Cod along with blowing snow. Mostly sunny elsewhere. Temperatures steady in the 20s. Wind N 10-20 MPH with higher gusts. Wind chill in the 10s.
TONIGHT: Partly cloudy with snow showers diminishing far eastern areas and mostly clear elsewhere. Lows 5-10 interior, 10s coast. Wind N to NW 10-20 MPH with higher gusts. Wind chill -5 to 0 interior, 0-10 elsewhere.
TUESDAY: Mostly sunny. Highs in the 20s. Wind NW 10-20 MPH and gusty.
WEDNESDAY: Mostly sunny. Lows in the 10s. Highs in the 30s.
THURSDAY: Mostly sunny. Lows in the 20s. Highs in the 40s.
FRIDAY: Increasing clouds. Lows in the 20s. Highs in the 40s.

DAYS 6-10 (JANUARY 9-13)…
A period of unsettled weather with temperatures near to above normal. Current timing suggests an insignificant storm of snow or mix to rain early January 9 followed by partial clearing later, another round of mix to rain later January 10 into January 11, and a third risk of precipitation later January 12 into January 13. Temperatures, though variable, will average near to above normal.

DAYS 11-15 (JANUARY 14-18)…
Mainly fair and colder early to mid period with a storm threat possible very late in the period.

8:04AM

DAYS 1-5 (JANUARY 3-7)…
No big changes today. Cold air coming. Watching for some ocean-effect snow showers Monday but it looks like the wind is northerly enough for the snow showers to only impact Cape Cod and Nantucket.
TODAY: Mostly sunny. Highs in the 30s. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Passing snow showers possible. Lows in the 20s. Wind NW 10-20 MPH and gusty.

WEDNESDAY: Mostly sunny. Lows in the 10s. Highs in the 30s.
THURSDAY: Mostly sunny. Lows in the 20s. Highs in the 40s.

DAYS 6-10 (JANUARY 8-12)…
There is plenty of uncertainty on how this 5-day period plays out as computer models are not handling the pattern well. This is a best-guess and subject to change. Storm passes south of the region January 8. Second storm brings light to moderate mix to rain January 9-10. Larger storm approaches by the end of the period. Temperatures near to above normal.

DAYS 11-15 (JANUARY 13-17)…
Storm threat very early in the period followed by fair weather much of the remainder of the period. Temperatures variable in the region early in the period depending on the behavior of potential storminess, briefly colder at mid period then moderating slightly.

9:08AM

DAYS 1-5 (JANUARY 1-5)…
Generally quiet pattern the next several days with the most important “event” being a shot of very cold air to start the coming week and some potential ocean-effect snow showers for a part of the region.
TODAY: Mostly sunny. Highs in the 30s. Wind W 10-20 MPH with higher gusts.
TONIGHT: Mostly clear. Lows 18-25. Wind W 5-15 MPH.

DAYS 11-15 (JANUARY 12-16)…
Storm threat early in the period followed by fair weather. Temperatures variable in the region early in the period depending on the behavior of potential storminess, briefly colder at mid period then moderating slightly.

9:18AM

HAPPY NEW YEAR! Wishing you all the best for 2016!

DAYS 1-5 (JANUARY 1-5)…
A quiet but somewhat colder pattern starts out 2016. First, an inversion followed by a trough will combine to cause some cloudiness and eventually a rain or snow shower in a few areas during today. The weekend will be dominated by high pressure, providing fair and seasonably chilly weather. A shot of very cold air will arrive by Monday and the wind may be just onshore enough to cause some snow showers over Cape Ann and the South Shore to Cape Cod of MA. High pressure brings dry and chilly weather Tuesday.
TODAY: Variably cloudy. A passing rain or snow shower this afternoon. Highs 37-44. Wind W 10-20 MPH.
TONIGHT: Partly cloudy. Passing snow showers early. Lows in the 20s. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Highs in the 30s. Wind W 10-20 MPH.
SATURDAY NIGHT: Mostly clear. Lows 18-25. Wind W 5-15 MPH.

MONDAY: Partly cloudy. Snow showers possible east coastal MA (Cape Ann, South Shore, Cape Cod). Lows in the 10s. Highs in the 20s.
TUESDAY: Mostly sunny. Lows in the 10s. Highs in the 30s.

DAYS 6-10 (JANUARY 6-10)…
Fair and milder January 6-7. Risk of rain or snow January 8. Fair and colder January 9-10.

DAYS 11-15 (JANUARY 11-15)…
Storm threat early to mid period followed by fair weather, brief cold then moderating again.

2:48AM

DAYS 1-5 (DECEMBER 31-JANUARY 4)…
For this final day of 2015 we’ll see a thawing of the foggy refrigerator that much of the region from the Boston area west and north became during the last couple days as a couple low pressure areas passed by with some cold air trapped near the surface. Today, we’ll see a drier westerly wind develop and temperatures will climb into the 40s, melting or softening much of the ice so it can be removed if it does not remove itself. The first 4 days of 2016 will see a trend toward colder weather. Some snow showers may be around Sunday from a cold front and Monday from a northeasterly flow off the ocean.
TODAY: Any early rain departs Cape Cod & Islands. Early areas of fog. Clouds to start, then more sun. Highs 40-46. Wind variable becoming W and increasing to 10-20 MPH with higher gusts.
THIS EVENING: Partly cloudy. Temperatures fall into 30s. Wind W 10-20 MPH. Wind chill in the 20s.
MIDNIGHT: Mostly clear. Temperatures 30-35. Wind W 5-15 MPH. Wind chill in the 20s.
OVERNIGHT: Mostly clear. Lows 25-30. Wind W under 10 MPH.
FRIDAY – NEW YEAR’S DAY: Mostly sunny. Highs 38-45. Wind W 5-15 MPH.
FRIDAY NIGHT: Partly cloudy. Lows in the 20s. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Highs in the 30s.
SUNDAY: Partly cloudy. Scattered snow showers. Lows in the 20s. Highs in the 30s.
MONDAY: Partly sunny. Scattered snow showers, favoring eastern MA. Temperatures fall into the 20s.

DAYS 6-10 (JANUARY 5-9)…
Fair and cold January 5. Fair and milder January 6-7. Risk of rain or snow January 8. Fair and colder January 9.

DAYS 11-15 (JANUARY 10-14)…
Fair and cold to start the period, then a risk of unsettled weather and moderating temperatures mid period. Fair and colder weather to follow that.

5:01AM

First, a brief look back at the messy little storm of Tuesday. Though the overall amounts of snow/sleet were close to forecast, the temperatures had me fooled. I should have thought a little more about the possibility of the secondary low to the south being strong enough to pull cold air southward but weak enough so that the result wasn’t a stronger east wind warming the lower atmosphere more than it did. So, icy ground was more common than I had expected and will continue into today for parts of the region as it is slow to warm.

DAYS 1-5 (DECEMBER 30-JANUARY 3)…
A weak low pressure system will approach from the southwest today as very weak high pressure sits to the north of the region. Some light rain may be around tonight, and may freeze on surfaces in lower elevations of interior southern NH and north central MA. It turns a little milder for New Year’s Eve with any early rain exiting southeastern areas and a mix of clouds/sun for the day. Fair weather and temperatures dropping through the 30s is expected for the nighttime festivities. It may be a little breezy but overall it will be quite nice compared to how cold it can be. The people won’t freeze, and the ice sculptures won’t melt. When we get to New Year’s Day itself, look for a pleasant but chilly day, perfect for outdoor hockey, and it just so happens that a match up between the Boston Bruins and Montreal Canadiens will take place that afternoon in the NHL Winter Classic at Gillette Stadium in Foxboro! Once we get to New Year’s Weekend, look for a trend toward colder weather. A disturbance may result in snow showers by Sunday.
TODAY: Mostly cloudy. Highs 35-40 except 40-45 Cape Cod. Light wind.
TONIGHT: Cloudy. Risk of rain mainly 9PM-3AM except freezing rain pockets in southern NH and interior MA. Lows 30-37. Light wind.
THURSDAY: Mostly cloudy morning with a risk of rain early Cape Cod. Clearing afternoon. Highs in the 40s. Wind light variable early becoming W and increasing to 10-20 MPH with higher gusts.
THURSDAY NIGHT – NEW YEAR’S EVE: Mostly clear. Evening temperatures falling into 30s. Overnight lows 25-32. Wind W 5-15 MPH, diminishing.
FRIDAY – NEW YEAR’S DAY: Partly cloudy. Highs 36-43. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Lows in the 20s. Highs in the 30s.
SUNDAY: Variably cloudy. Chance of snow showers. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (JANUARY 4-8)…
A couple shots of colder air bring overall temperatures close to seasonal normals during this period, though they will be variable day to day, with mainly dry weather.

DAYS 11-15 (JANUARY 9-13)…
May have to watch for a storm system later in the period after it starts out mainly dry and chilly.

2:56AM

DAYS 1-5 (DECEMBER 29-JANUARY 2)…
Unsettled as expected today with a mix of precipitation, a break early Wednesday then a second wave of lighter precipitation coming as rain Wednesday night lingering into early Thursday to the southeast of Boston then a mainly dry remainder of New Year’s Eve. The first couple days of 2016 will feature fair and somewhat colder weather.
EARLY MORNING: Overcast with snow/sleet northwest of Boston, sleet/rain Boston and southern suburbs, rain to the southeast including Cape Cod, with accumulation of snow/sleet up to 2 inches I-495 belt north of the Mass Pike, up to 1 inch in the I-95 belt north of the Mass Pike, with trace amounts just to the south and east. Temperatures steady 25-30 interior southern NH to north central and interior northeastern MA, 30s elsewhere. Wind light NE in areas where precipitation is frozen and E 5-15 MPH elsewhere.
LATE MORNING: Overcast. Sleet/rain northern areas, rain elsewhere but pockets of freezing rain especially valley locations in interior northeastern to north central MA and southern NH. Temperatures in the 30s, coldest to the north and west of Boston. Wind E 5-15 MPH.
AFTERNOON: Cloudy. Rain becoming spotty. Highs 35-42. Wind E to NE 10-20 MPH, higher gusts Cape Cod.
TONIGHT: Mostly cloudy. Spotty light drizzle or freezing drizzle. Lows 28-35. Wind NE to N 10-20 MPH.
WEDNESDAY: Mostly cloudy. Highs 35-42. Wind variable 5-15 MPH.
THURSDAY – NEW YEAR’S EVE: Mostly cloudy early with a chance of rain Cape Cod. Partly sunny midday and afternoon. Partly cloudy evening and night. Early morning lows 30-37. Daytime highs in the 40s. Evening to late night temperatures falling through the 30s.
FRIDAY – NEW YEAR’S DAY: Mostly sunny. Lows in the 20s. Highs around 40.
SATURDAY: Mostly sunny. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (JANUARY 3-7)…
A few snow showers with a disturbance January 3. Fair and cold January 4-5, milder January 6-7.

DAYS 11-15 (JANUARY 8-12)…
Unsettled weather possibly early and again late in the period as the southern storm track becomes a little more active but probably keeps most of its energy south of southern New England while air mass changes are driven by the northern jet stream making for variable but mostly near normal temperatures.

7:16AM

DAYS 1-5 (DECEMBER 28-JANUARY 1)…
Cold air settles in today with fair and windy weather as high pressure builds to the north of New England. Low pressure tracks into the Great Lakes and redevelops near the New England South Coast Tuesday bringing a period of precipitation, starting as a snow to sleet transition then eventually to rain before ending. The longest period of frozen precipitation will be north of Boston where some minor accumulation is likely, but overall warm air from the ocean and above normal ocean water temperatures will be too influential and the rain wins out. In addition, dry air working in from the west will shut off the making of precipitation by later Tuesday afternoon and only low level moisture will be available for additional rain/drizzle, where it will be far too mild for any frozen precipitation. A brief break early Wednesday before a second wave of low pressure brings brief rain late Wednesday. A drier and cooler trend arrives for the final day of 2015 and the opening day of 2016.
TODAY: Mostly sunny. Highs in the 30s. Wind N 10-20 MPH, diminishing late.
TONIGHT: Clouding over. Snow/sleet developing before dawn, rapidly mixing with rain near the coast, and probably starting as a mix and going right to rain closer to the South Coast and Cape Cod. Lows in the 20s southern NH and northern MA and 30s elsewhere. Wind light E.
TUESDAY: Cloudy. Snow/sleet north and west, sleet/rain south, transitioning to all rain then tapering off later to light rain/drizzle. Areas of fog. Snow/sleet of a trace to 1 inch mainly Boston area west and north with around 2 inches possible Merrimack Valley into southern NH away from the coast. Highs 35-43. Wind SE 10-20 MPH.
WEDNESDAY: Variably cloudy. Chance of light rain at night. Lows in the 30s. Highs in the 40s.
THURSDAY – NEW YEAR’S EVE: Partly sunny. Temperatures steady in the 40s.
FRIDAY – NEW YEAR’S DAY: Partly cloudy. Lows in the 20s. Highs 35-45.

DAYS 6-10 (JANUARY 2-6)…
A pattern change brings seasonably cold to slightly above normal temperatures and mainly dry weather during the period.

DAYS 11-15 (JANUARY 7-11)…
A continuation of a seasonably chilly to slightly milder than normal pattern with again mainly dry weather as southern jet stream energy likely remains too far to the south for impact and northern jet stream energy remains fairly weak with no more than a couple very light precipitation events.
