From the WABI-TV5 & CW Forecast Center:
The ridge of arctic high pressure that produced the unseasonably cold weather across our region since Sunday will slip east into the Canadian Maritimes today. As the high moves east of our region today clouds will begin to move into New England from the west. The clouds will be associated with a storm riding east through the Great Lakes region. The storm will bring a period of precipitation to our region later tonight and Thursday morning. Precipitation will start out as snow all across the Pine Tree State tonight, but with the storm sliding up to the west of New England early Thursday a developing southerly breeze will cause the snow to mix with or change to rain over southern and coastal Maine Thursday morning, while it remains mostly snow across the far north. Snowfall later tonight and Thursday morning will range from an inch or two along the coastline to 2 to 5″ across the north.
Weak high pressure will produce generally fair and seasonably cool 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. At this point in time it appears much of the precipitation will fall as snow or mixed precipitation as the storm center will likely slide just to the south of Maine. More unseasonably cold air will spill into New England as the workweek begins next Monday.
Today: Increasing clouds, with high temps in the low to mid 30s.
