From the WABI-TV5 & CW Forecast Center:
High pressure will bring fair and cold weather to Maine Saturday. High temps Saturday will range from the high single numbers north to the low 20s near the coastline. The high will slip off to our east Sunday and a southerly breeze will develop here. The southerly wind will usher a milder airmass into our region as high temps reach the 20s north to low 30s south.
A storm will bring a mixed bag of precipitation to New England later Sunday night and Monday as it slides up over or just to the west of Maine. Early morning mixed precipitation Monday will likely change to a period of plain rain as temps briefly rise to well above freezing. Rain may briefly change back to snow before ending as an arctic cold front sweeps east through our region later in the afternoon. More frigid air will spill into the Northeast as the storm lifts into southern Canada Monday night and Tuesday.
Tonight: Partly cloudy, diminishing wind and frigid, with low temps between -25 and -5.
Saturday: Partly cloudy, with high temps in the upper single numbers to low 20s from north to south.
Saturday night: Variably cloudy, with low temps in the single numbers to low teens.
Sunday: Partly sunny then increasing clouds, with snow and mix developing at night and high temps in the mid 20s to low 30s.
Monday: Early wintry mix to rain, with high temps in the mid 30s to mid 40s from north to south.
Tuesday: Partly cloudy, with mountain flurries, windy and frigid, with high temps in the single digits to mid teens.
Wednesday: Partly sunny, with high temps in the teens to low 20s.
