Forecast: Bitter Cold Monday, More Snow Expected Tuesday

Cold arctic high pressure will build into the region Monday, with temperatures in the 20s throughout the day. A gusty wind is going to make it feel even colder, with wind chills in the single digits at times.

As the full "cold moon" rises overnight, temperatures will plummet to the single digits, even in Boston, Tuesday morning. The only place to escape the bitter cold Tuesday morning will be Cape Cod and the Islands.

A low pressure area will dive south from Canada Tuesday and bring a swath of snow for the late morning and early afternoon. While the storm isn’t big, it will be poorly timed arriving during the afternoon commute.

Dry weather returns Wednesday with cold air. A warming trend takes us to the close of the workweek when most will experience temperatures in the 40s.

Monday: Sunny, blustery and cold. Highs 21-30

Overnight: Clear and cold. Lows 2-12 but 17-22 over Cape Cod/Islands.

Tuesday: Cloudy with a period of snow beginning late morning and ending during the evening between 7 p.m. and 10 p.m. Boston may see between two-to-four inches. Cape Cod will likely see about an inch of snow, that will eventually turn to rain.

Wednesday: Mostly sunny and cold. Highs 29-35.

Thursday: Milder.
