DAYS 1-5 (JANUARY 8-12)
A compact storm intensified and moved very rapidly southeast of New England overnight, concentrating most of its snow shield across Cape Cod and sparing everyone else. With this largely non-event offshore and on the way out, we look ahead to the upcoming active pattern and basically summarize yesterday’s discussion. An arctic cold front crosses the region this afternoon with the risk of a few snow showers and snow squalls, so be on the look-out as those can quickly reduce visibility and in some cases coat the ground with snow. Wind and cold will be the story to end the day and through tonight. Thursday, as many have been since November, will be the coldest day of the week. A warm front cross the region Friday with a touch of rain or inland sleet possible as we quickly lose the cold both at the surface and aloft. Saturday’s weather will remind you of a spring day as we get into a gusty southwesterly wind flow and very mild air, with some high temperature records challenged. Boston’s record high for the date is 62 and there is a risk of reaching that. A strong but slow moving cold front will push through the region Saturday night and early Sunday with a band of rain, which may end as sleet/snow for parts of the region if the cold air is in while the precipitation is still around. At the moment, leaning toward the precipitation to win the race.
TODAY: Sun/cloud mix. Passing afternoon snow showers possible. Risk of a brief snow squall mid to late afternoon first west, lastly east. Highs 32-39. Wind W increasing to 15-25 MPH with higher gusts, shifting to NW late.
TONIGHT: Clear. Lows 15-22. Wind NW 10-20 MPH with higher gusts, diminishing overnight.
THURSDAY: Sunshine and high clouds. Highs 25-32. Wind variable up to 10 MPH.
THURSDAY NIGHT: Increasing clouds. Lows 18-25 evening, rising slowly overnight. Wind SE under 10 MPH.
FRIDAY: Mostly cloudy. Scattered light rain, possibly some sleet interior areas, favoring the morning hours. Highs 40-47. Wind SE under 10 MPH shifting to SW up to 10 MPH.
FRIDAY NIGHT: Mostly cloudy. Temperatures steady 40-47 evening, rising to 50-57 overnight. Wind SW 5-15 MPH, higher gusts.
SATURDAY: Variably cloudy. Risk of a passing rain shower. Highs 55-62. Wind SW 10-20 MPH, higher gusts.
SATURDAY NIGHT: Cloudy. Rain likely. Lows 48-55. Wind SW 5-15 MPH shifting to N.
SUNDAY: Cloudy. Rain ending in the morning. Temperatures fall through the 40s into the 30s. Wind N 5-15 MPH, higher gusts.
DAYS 6-10 (JANUARY 13-17)
Two low pressure systems likely impact the region, about January 14 and 16, based on current timing, with rain favored over snow, along with mostly above normal temperatures, but a subtle shift can change these tracks and temperatures, so need to keep an eye on it.
DAYS 11-15 (JANUARY 18-22)
Still looking at a similar pattern of active weather, probably needing to watch 1 or 2 additional low pressure systems bringing precipitation threats.
