From the WABI-TV5 & CW Forecast Center:
The warm and muggy pattern all across the Northeast will continue right into the upcoming weekend. Tonight will be partly cloudy and mild, with patchy fog developing after midnight and low temps will range from the upper 50s to mid 60s all across the Pine Tree State. High pressure just to our south will produce a partly sunny and warm start to our Thursday, but an approaching weak cold front will likely fire up some scattered afternoon and evening thunderstorms. Some of the storms later tomorrow afternoon and evening could become strong to severe as the cold front begins to move east through New England. Once again it will be warm throughout Maine tomorrow, with high temps mostly running in the low to mid 80s inland, but likely hold in the upper 70s along the coastline due to a developing onshore breeze.
Friday will be partly sunny and warm, but once again a weak disturbance aloft sliding east across Quebec might kick off an isolated storm or two, but most of the day will be rain free. A bubble of high pressure will likely bring partly sunny, warm and rather humid conditions to our region as we start the weekend Saturday, with high temps generally running in the low to mid 80s. Sunday will also turn out partly sunny and warm, with the risk of a few hit and miss thunderstorms developing. Monday will be another warm and rather muggy day, with a better chance for some scattered thundershowers as a stronger upper level disturbance along with a cold front begin to enter the Northeast.
Tonight: Partly to mostly clear, with a light wind and areas of fog forming, with low temps in the upper 50s to mid 60s.
Thursday: Partly sunny, warm and muggy, with a southeast breeze under 10 mph along with scattered afternoon and evening thunderstorms and high temps in the upper 70s at the coast and low to mid 80s inland.
Friday: Partly sunny, with a few widely scattered thunderstorms possible and high temps in the low to mid 80s.
Saturday: Partly sunny and warm, with isolated thunderstorms possible and high temps in the upper 70s to mid 80s.
Sunday: Partly sunny and warm, with a scattered shower or storm possible and high temps in the upper 70s to mid 80s.
Monday: Variably cloudy, warm and humid, with scattered thunderstorms likely and high temps in the 80s.
