From the WABI-TV5 & CW Forecast Center:
High pressure will move east across New England early today and bring a mostly sunny start to the day. As the high departs to our east clouds will begin to increase across the Pine Tree State later this afternoon as a storm over the Great Lakes Region begins to head northeast. While the initial storm moves up to the west of New England tonight, a secondary storm will develop over southern New England. The new secondary storm will slide northeast and bring a mixed bag of precipitation to our region later tonight and Saturday morning. The wintry mix of precipitation will turn to mostly rain over much or our region Saturday morning as temps warm to the upper 30s north and low to mid 40s south. Northern parts of Maine might see a couple of slushy inches of snow late tonight and early Saturday, but elsewhere across the state little if any snow will accumulate. Rain and mixed precipitation will taper off later Saturday afternoon as the primary and secondary storms lift up into southeastern Canada.
An upper level low over Quebec will keep skies mostly cloudy up north Sunday, while the rest of the region turns partly sunny. Temps Sunday will run a few degrees below normal. High pressure will bring fair and pleasant weather to our region Monday, with a storm likely bringing rain back to Maine later Monday night and Tuesday. Fair weather will return to Maine Wednesday as the storm lifts up into Canada.
