Rain Ending Tonight, Partly Sunny & Mild Wednesday 

From the WABI-TV5 & CW Forecast Center:


The combination of an approaching cold front and a small storm riding up through the Gulf of Maine will continue to bring our region periods of rain this evening. The rain will taper off and end later tonight as the front slips offshore and the storm moves into Nova Scotia. Slightly colder air behind the front may allow the rain to briefly change to snow across northwestern parts of Maine before ending, but any snowfall accumulations up north will likely be 1” or less. Skies will partially clear late tonight, but lingering low level moisture could lead to areas of fog, and patchy black ice forming around daybreak. Weak high pressure will bring partly sunny skies and unseasonably mild weather to New England tomorrow, with high temps ranging from the upper 30s to mid 40s across our area.

An upper level trough will gradually develop over the eastern parts of the U.S. as we head through the rest of the workweek and into the weekend. The trough will cause a series of storms to develop near the Eastern Seaboard as we progress through the week. The first small storm will likely remain mostly offshore Thursday, with just a slight chance of seeing some light rain and snow showers across Maine. Weak high pressure will bring partly sunny skies to our region Friday before a stronger storm develops off the Mid-Atlantic Coastline Friday night. This new storm will intensify as it moves northeast, but it is too early to tell if the storm will be close enough to Maine Saturday to produce accumulating snowfall here. Behind the Saturday storm a gusty northwest breeze will develop and help usher a much colder airmass into New England for Sunday and Monday.


Tonight: Periods of rain, then partial clearing late, with patchy fog forming and low temps in the mid 20s to mid 30s.


Wednesday: Partly cloudy and mild, with high temps in the mid 30s to mid 40s from north to south.


Thursday: Variably cloudy, with a few light rain and snow showers possible and high temps in the mid 30s to low 40s.


Friday: Partly to mostly cloudy, with high temps in the 30s.


Saturday: Snow and mixed precipitation likely, with high temps in the upper 20s to mid 30s.


Sunday: Variably cloudy and cold, with snow showers likely and high temps in the teens north and 20s south.
