From the WABI-TV5 & CW Forecast Center:
The muggy air mass and the disturbance aloft are creating some scattered strong thundershowers this evening. Some of the storms will be strong to severe with frequent lightning and winds of up to 60 mph possible.
Thursday showers and storms continue in the afternoon and evening with the chance for strong to severe storms possible again. They could produce strong winds, heavy downpours and even hail.
The front will gradually push offshore later in the day or at night on the Fourth and the showers will tend to taper off from west to east. Cooler, drier and less humid air will filter into Maine on a northwest breeze once the cold front slips offshore. High pressure approaching New England from the west will likely bring brighter skies to Maine beginning Saturday. The high should bring fair and seasonably mild weather to our region Sunday.
*The only question mark for the holiday and the early part of the weekend forecast is the possibility of now Tropical Storm Arthur tracking close enough to our region Friday and part of Saturday to bring more showers and some gusty winds to especially eastern parts of the state. At this point in time it appears that Arthur will bring some rain and wind to especially eastern parts of our region. We will keep you posted on any projected track changes.
Tonight: Partly to mostly cloudy, and muggy, with widely scattered thundershowers and lows in the mid to upper 60s.
Thursday: Muggy, with showers and storms likely and high temps in the mid 70s to low 80s.
Friday: Showers and storms likely, with high temps in the 70s to near 80.
Saturday: Partly sunny and less humid, with high temps in the 70s to near 80.
Sunday: Mostly sunny, with high temps in the mid 70s to low 80s.
