DAYS 1-5 (JANUARY 31 – FEBRUARY 4)
A cold front passing through the region overnight brought with it a swath of precipitation, generally light, starting as rain for some areas but winding up as snow, enough for a coating on some surfaces. This lingers from the south Coast to MA South Shore early this morning before moving out, followed by some clearing and a slightly colder day today end the month of January, which was very mild overall. February opens with a couple seasonably cold days and dry weather with high pressure in control. A wave of low pressure may just clip the Cape Cod / Islands region with a bit of light snow first thing Wednesday morning. On Friday, a sharp arctic cold front will move quickly through the region, and may be accompanied by a brief snow shower or snow squall. It opens the door to a quick-hitting blast of dangerously cold air, the coldest since February 14 of 2016. The core of the cold will be timed so that nearly the entire region falls below zero for Saturday morning, but there will be a period of dangerously cold wind chill temperatures starting later in the day Friday and not easing up until later in the day Saturday, so about 24 hours.
TODAY: Cloudy start with lingering rain to mix South Coast, and light snow just inland from South Coast to South Shore of MA, ending by mid morning. Sun returns thereafter from west to east. Highs 32-39. Wind NW 10-20 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 23-30. Wind W 5-15 MPH, higher gusts.
FRIDAY: Partly cloudy with a passing snow shower/squall possible morning, then sunny. Highs 25-32 early, then falling through the 20s and 10s to below 10 by evening. Wind W 5-15 MPH with higher gusts, shifting to NNW 10-20 MPH with higher gusts. Wind chill falling below zero during the afternoon.
FRIDAY NIGHT: Clear. Lows -15 to -10 in interior southern NH and north central MA to -10 to -5 from the NH Seacoast through the interior portions of eastern MA to -5 to 0 in the I-95 belt from northeastern MA to northern RI, and 0-5 along the South Coast. Wind NNW 15-25 MPH, higher gusts. Wind chill -20 to -40 at times.
SATURDAY: Sunny. Late-day highs 8-15. Wind NW 15-25 MPH and gusty, diminishing later in the day. Wind chill as low as -25 to -35 in the morning, easing slowly as the day goes on.
DAYS 6-10 (FEBRUARY 5-9)
Quick warm-up Sunday February 5 comes with a chance of some snow then rain. Watching a wave of low pressure to potentially bring some rain/mix/snow to southeastern areas early Monday otherwise dry, turning colder later in the day but not nearly as cold as the previous shot. Seasonable cold for the middle of next week – maybe with brief precipitation then a return to dry weather.
DAYS 11-15 (FEBRUARY 10-14)
Watching for potential wintry precipitation episodes mid period with variable temperatures.
