From the WABI-TV5 & CW Forecast Center:
The ridge of high pressure that brought the bright and cold conditions to New England today is currently moving east off the Mid-Atlantic Coastline. As the high slips offshore this evening clouds ahead of a storm and its associated warm front will quickly increase across our region. The warm front will slide northeast across New England later tonight and early tomorrow morning as the surface storm slides up through the Eastern Great Lakes region tonight and into southwestern Quebec tomorrow morning. The warm front will bring a period of snow to Maine overnight as it approaches and then crosses our region. The bulk of the snow will fall in our area from about 9pm to around 4am. Snowfall from this quick moving front and storm will generally range from 2 to 5” across all of the Pine Tree State. The precipitation may briefly mix with a little rain or freezing rain before ending along the coastline late tonight, but the bulk of the precipitation will fall as snow.
A southwest breeze behind the warm front will bring a brief warm-up to our region tomorrow as high temps climb into the mid 30s to mid 40s as skies turn partly sunny. The warm up won’t last very long as an arctic cold front slips south across New England later tomorrow night or early Thursday morning. Once the cold front slips off to our south a new shot of arctic air will send temperatures tumbling for Thursday as highs only climb into the upper teens to mid 20s despite some partial sunshine. Arctic high pressure will bring bright but unseasonably cold conditions to Maine as we end the workweek Friday. The weekend will remain cold all across the Northeast, with just the chance of a few snow showers popping up in our region both days as a couple of disturbances aloft sweep south out of Canada and cross Northern New England.
Tonight: Thickening clouds, with a period of snow and a southerly breeze at 7 to 14 mph and low temps in the teens to mid 20s.
Wednesday: Partly sunny, a bit breezy and milder, with high temps in the mid 30s to mid 40s from north to south.
Thursday: Partly sunny, breezy and colder, with high temps in the upper teens to mid 20s.
Friday: Bright and cold, with high temps in the mid teens to low 20s.
Saturday: Variably cloudy, with scattered snow showers likely and high temps in the upper teens and 20s.
Sunday: Scattered snow showers, with high temps in the 20s to near 30.
