From the WABI-TV5 & CW Forecast Center:
The combination of strong arctic high pressure over southern Quebec and an intensifying storm off the Mid-Atlantic coastline will bring a strong and gusty wind to our area tonight and Friday. The gusty wind will combine with bitterly cold temps to produce dangerous wind chill values tonight and tomorrow morning of between -25 and -45. The high to the north will keep northern parts of Maine dry tonight and Friday, while the storm off the Mid-Atlantic Coastline will bring snow to Maine from about the Bangor region on south. Snowfall from Augusta to Bangor and over to Calais will likely range from 1 – 4” tonight and tomorrow morning, with areas further north receiving 1” or less. The Downeast Coastline will likely pick up between 2 to 5”, with the Mid-Coast of Maine picking up between 5 to 9”. The Portland region on south through Kittery will likely see between 8 and 12” accumulate by the time the snow tapers off tomorrow. Low temps tonight will range from -25 up north to about -5 along the coastline.
As the storm to our south races northeast tomorrow the skies across our region will partially clear. A stiff north to northwest wind will continue to usher bitterly cold air into New England tomorrow as high temps hold in the single digits below zero north to the single digits above zero from the Bangor region on south. High pressure will bring fair and cold weather to Maine Saturday. 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. More frigid air will spill into the Northeast as the storm lifts into southern Canada Monday night and Tuesday.
Tonight: Breezy and bitterly cold, with periods of snow from the Bangor region on south and low temps between -25 and -5.
Friday: Morning snow south tapering off, blustery and frigid, with high temps ranging between -8 and +8 from north to south.
Saturday: Partly cloudy, with high temps in the teens to low 20s.
Sunday: Partly sunny then increasing clouds, with snow and mix developing at night and high temps in the mid 20s to low 30s.
Monday: Wintry mix to rain, with high temps in the mid 30s to mid 40s from north to south.
Tuesday: Partly cloudy, windy and frigid, with high temps in the single digits to mid teens.
