A few light showers/sprinkles will be rolling through this evening ahead of a low pressure center which will be tracking from the Ohio Valley and west of New England Saturday. Most of these showers will be light ahead of a warm front. Temps will cool into the 30’s overnight and remain steady with light Southwest winds. We’ll have to watch for a few pockets in the western valleys which could drop down to near 32 for a few pockets of light freezing rain…even some light snow across the hilly terrain of the north.

Further south, after midnight towards daybreak I expect the rain to become most steady with the warm front directly over southern New England at the crack of dawn. Morning showers will linger through the late morning along the coast. Showers will be mainly over by afternoon. NNW winds will lock in low clouds and a cool feel especially north and NW of Boston where highs will only be in the 30’s and Lwr 40’s. South of Boston highs will climb into the mid -upper 40’s with the passage of the warm front in the afternoon.

A cold front will push through Saturday night with some partial clearing overnight. High pressure builds in Sunday with plenty of Sunshine, a few fair weather clouds. A great end to the weekend with seasonal highs in the 40’s to near 50.

Clouds will advance again late Sunday through Sunday night in advance of another warm front. Light rain will again begin to break out after sunset and become heavier after midnight. With cold high pressure to the north supplying cold air at the surface under light northerly winds, there is the potential that we will be seeing a better chance for accumulating freezing rain in the NW valleys from SNH, SVT and Western MA. This could be a problem for the Monday morning commute for people in these outlying areas for icy spots early.

For the rest of us, Monday will start off with showers with a warm front sitting over us once again. Showers will lift north during the morning with the warm front with mild SW winds following in behind. Plenty of clouds will linger but highs will be able to climb well into the 50’s nearing 60. A cold front will be sliding from west to east Monday night which could make for a wet game at Foxboro for Monday night football vs the Texans…but it will be mild near 50.

Once the front is off the coast, we will have to watch for a wave of low pressure to tracking up along this front off our coast. There is more uncertainty with this part of the forecast as some of the models are a bit more progressive. This low will likely track south of New England with rain changing to snow as the low pulls away. There is potential accumulating snowfall NW of Boston in this change over if it happens like this…but not more than a few inches are expected.

Once this wave pulls away we should be looking at several days of sunshine with cool air in the 30’s Wednesday warming into the 40’s to near 50 to end the week. By the weekend of 15-17th we will likely be tracking another storm system which will be crossing near us but it is impossible to know which path it will ultimately take. It should have quite a bit of moisture to work with but very track dependent at this point.
