A storm center will continue moving east of New England today, headed toward Nova Scotia. The pressure difference/gradient between that low center and a high in the Midwest will produce an increasing northwest wind across the region today, picking up to 12-25 mph, with gusts to 40+ mph possible this afternoon. Skies will become partly sunny, however some flurries or snow showers are possible, especially across the western hills later this afternoon and evening as a short wave disturbance aloft moves over New England. Highs will reach the 40's today, however it will turn a lot colder tonight and remain windy. Lows will drop to 18-24, but the wind-chill will fall into the single numbers and teens. Some flurries or snow showers could linger in the hills. Tuesday will be mostly sunny, but windy & cold, with daytime temperatures having trouble getting out of the 20's. Winds will diminish Tuesday night under a clear sky, as low temperatures drop into the teens. The quick shot of arctic air will start to moderate Wednesday as the high pressure system builds in from the west. Temperatures will actually be pretty moderate this week, with the exception of tonight, Tuesday & Tuesday night. Wednesday will be mostly sunny and pleasant (for December), with highs in the low 40's. Thursday looks dry with highs in the 40's. The next likely precipitation arrives by Friday, in the form of rain.
