Today is another mild day with highs getting back into the 40s. It's a good idea to get outside for a walk or a run today as the weather starts going downhill for the start of the weekend.
Temperatures, which have been so mild this week are going to return to cold and eventually bitter cold levels later next week. Without any snow covering the ground, it might be a bit easier to bear.
Saturday's weather will likely be the worst of the weekend, with a few showers or rain and snow. Across northern Worcester County there could be some light accumulation of snow on the higher hilltops. It won't be a storm worthy of plows, but the light snowfall could whiten the ground and cover the grass.
Sunday looks to be drier, but colder with highs remaining in the 30s. There will still be a lot of clouds and a stray flurry.
Monday is a very typical mid-January day. The roads will be dry, and there won't be any fog so the commute should only be hampered by car volume, not weather.
The arctic air returns for Tuesday and the rest of next week. There will likely be a day or two when temperatures don't get out the teens in Boston and lower 20s over Cape Cod. At night, with a strong wind at times, wind chill readings could plummet to 20 below, more on this next week.
Today: Mostly sunny and comfortably cool today. Highs between 40 to 46.
Tonight: Cloudy and cool. Lows 29 to 35.
Saturday: Cloudy with a period of rain or snow showers. It won't be damp the entire day. Some light accumulation of snow over northern Worcester County. Highs 32 to 38.
Saturday night: Snow showers ending and turning colder. Lows 23 to 29.
Sunday: Partly cloudy. Lows 21 to 28.
Monday: Mostly sunny, with a highs in the mid-30s, except north and west of route 495 where lower-30s will persist.
