From the WABI-TV5 & CW Forecast Center:
The core of the arctic airmass that has produced the bright, blustery and unseasonably cold conditions across Maine today will slip off to our northeast tonight. As the cold air retreats to our northeast moisture will begin to push back into Maine from the southwest and after a mostly clear start tonight clouds will roll back into our region after midnight.
The ridge of high pressure currently over southwestern Quebec will slip off to our southeast tomorrow morning and a developing southwest breeze on the backside of the high will allow a somewhat milder airmass to move up into our region. As the milder air tries to move into Maine light snow and mixed precipitation will break out across the state from west to east, but at this time it appears the precipitation will be rather light, with only a coating to possibly 2” of snow accumulating by the time the precipitation tapers off tomorrow evening. Skies will become partly sunny Saturday as high pressure builds into our area from the northwest. The high should bring mostly fair and cool conditions to Maine Sunday, with an approaching storm likely bringing some mixed snow and rain back to New England for Sunday night and Monday.
Tonight: Increasing clouds, with a northwest breeze diminishing to under 10 mph and low temps in the mid single numbers to mid teens.
Friday: Mostly cloudy, with a southerly breeze around 10 mph and occasional light snow and mixed precipitation developing and high temps in the 30s.
Saturday: Partly sunny, brightest north, with high temps in the mid 30s to mid 40s from north to south.
Sunday: Becoming mostly cloudy, with high temps in the 30s.
Monday: Mostly cloudy, with snow and rain likely and high temps in the 30s to low 40s.
Tuesday: Variably cloudy, with possible light mixed precipitation and high temps in the upper 30s to mid 40s.
