From the WABI-TV5 & CW Forecast Center:
A cold front currently sliding across New England continues to produce scattered showers and thundershowers as it tracks east. The combination of a humid airmass over Maine, upper level energy and the approaching cold front have combined to produce some scattered severe storms in our area this afternoon. The scattered strong to severe storms will continue through this evening and then begin to diminish by midnight. The stronger storm will contain a strong and gusty wind, briefly as high as 60 mph, along with heavy downpours, hail and frequent dangerous lightning. As the cold front slips offshore the showers and stronger storms will taper off and end, but patchy dense fog will likely form late. Humidity levels will also begin to drop once the cold front slides off to our east tonight, with low temperatures dipping into the mid 50s to low 60s by daybreak tomorrow.
A westerly breeze behind the cold front will usher a cooler airmass into New England beginning later tonight and lasting through the rest of the workweek. An upper level trough crossing New England tomorrow will keep the risk of showers and thundershowers going all across the Pine Tree State, with a few hit and miss strong to severe storms possible during the afternoon. Under variably cloudy skies the high temps in our area will run in the 70s.
A surface ridge of high pressure approaching the Northeast from the west will bring brighter skies to Maine Thursday and Friday, but a pool of cool air aloft will still likely kick off some hit and miss showers, mostly over far northern parts of the state. Temps late this week will run well below normal as highs range from the upper 60s to mid 70s from north to south in Maine. An unusual storm system for summer will likely developing along or just off the Mid-Atlantic Coastline late this week and then move northeast from there. It is still too early to tell if the storm system will impact parts of Eastern New England with rain and wind or stay safely out to sea.
Tonight: Scattered strong to severe thunderstorms this evening, with some of the thunderstorms containing a strong and gusty wind, hail and torrential downpours. Showers and storms will taper off and end later tonight, with lowering humidity and areas of fog forming, with low temps in the mid 50s to low 60s.
Wednesday: Variably cloudy, with scattered showers and thunderstorms along with a westerly breeze at 6 to 12 mph and high temps in the 70s.
Thursday: Partly sunny, breezy and cool, with a few scattered showers possible north and high temps in the upper 60s to mid 70s.
Friday: Partly sunny, with high temps in the upper 60s north and 70s south.
Saturday: Partly to mostly cloudy, with high temps in the upper 60s and 70s.
Sunday: Variably cloudy, with possible showers and high temps in the upper 60s and 70s.
