From the WABI-TV5 & CW Forecast Center:
High pressure will continue to bring colder than average temps to Maine today through Wednesday as the high slowly drifts east across southeastern Canada. Temps will slowly modify the next couple of days, but still run several degrees below average today and near average Wednesday.
Over the next couple of days a storm will move from the Pacific Northwest towards the Great Lakes. The storm will likely pass up to the west of New England later Wednesday night and Thursday and that will cause the temps to warm up a bit Thursday. As the storm’s warm front approaches Maine light snow and mixed precipitation will likely develop across in our area later Wednesday night, but with the storm passing up to our west a southerly wind will bring milder air and a change to rain across much of the Pine Tree State Thursday. Temps in Maine Thursday will likely reach the mid to upper 30s north of the Bangor region, with highs reaching the low to mid 40s from Bangor on south.
Weak high pressure will produce generally fair and seasonable conditions here Friday. A new storm will approach New England from the southwest over the weekend and that will likely bring a new round of precipitation to our region later Saturday into early Sunday. The exact track of the storm will determine whether the precipitation falls as rain, snow or a mix. More unseasonably cold air will spill into New England as the workweek begins next Monday.
Today: Mostly sunny and still cold, with high temps in the low 20s to low 30s from north to south.
Wednesday: Partly sunny then increasing clouds, with possible snow and mixed precipitation later at night and high temps in the 30s.
Thursday: Morning rain and snow, with high temps in the mid 30s to mid 40s from north to south.
Friday: Partly sunny, with high temps in the 30s.
Saturday: Mostly cloudy, with snow and rain likely developing and high temps in the 30s.
