It won’t get very warm today as we add very little to the temperatures even by 1 or 2 p.m. this afternoon. The high in Boston will reach about 20.
The storm could move slightly farther west to bring some light snow into Boston late tonight or early Wednesday morning. If this does occur, I am not expecting more than a coating to an inch, but it would affect the Wednesday morning commute.
After this system passes out to sea, the pattern will undergo a change. Temperatures will return closer to seasonal norms for the end of the week and the weekend. As another weak area of low pressure approaches Saturday there could be some periods of snow or rain showers. This will be our third Saturday in a row with precipitation.
Tuesday: Mostly sunny with a brisk breeze. Highs 16 to 23.
Tuesday night: A period of snow late at night over Cape Cod. Snow may reach Boston after 3 a.m. for a couple of hours. Little or no snow accumulation north of Plymouth. One to 3 inches over the Cape and the islands (3 to 5 in Nantucket).
Wednesday: Any snow ends early. Then sunny with highs in the mid-20s.
Wednesday night: Mainly clear and cold. Lows 1 to 10 in Boston. Low teens on the Cape.
Thursday: Sunny with highs in the upper-20s.
Thursday night: Partly cloudy and not so cold. Lows in the teens to low-20s.
Friday: Partly sunny with a high of 33 to 38.
Friday night: Mostly cloudy with a low around 25.
Saturday: Lots of clouds with a sunny break or two. A chance of showers with a high of 35 to 40.
