From the WABI-TV5 & CW Forecast Center:
High pressure to our north will force a series of weak storms to pass offshore well south of Maine as they move from the Ohio River Valley to well off the Mid-Atlantic Coastline today through Saturday. With the storm track later this week remaining well south of Maine the skies across our region should average partly sunny and temps will run in the 70s to near 80 this afternoon and be a bit cooler Friday and Saturday as a slightly cooler airmass filters south into New England from the Canadian Maritimes. A northeast breeze late this week will keep the temps coolest along the coastline both Friday and Saturday. A couple of weak disturbances aloft today through Saturday will keep the atmosphere a bit unstable and that could lead to a few widely scattered showers popping up across the Pine Tree State, but most towns will likely not see them. The best chance for seeing a brief shower or two over the next couple of days will be over the western parts of Maine.
The high to our north will slowly settle south later in the weekend and early next week. The high will once again bring mostly sunny skies to Maine Sunday through Tuesday. As the high settles to our south a southwest breeze will develop all across New England and that will cause temps to warm back up to above normal levels. Temps Sunday will run in the 70s but on Monday and Tuesday they will likely climb into the lower 80s across much of Maine.
Today: Mixed sun and clouds, with widely scattered showers possible and high temps in the 70s to near 80.
Friday: Variably cloudy, with stray showers possible and high temps in the low to mid 70s.
Saturday: Partly sunny, with high temps in the upper 60s to mid 70s.
Sunday: More sun than clouds, with high temps in the mid 70s.
Monday: Mostly sunny, with high temps in the mid 70s to lower 80s.
Tuesday: More sun than clouds, with high temps in the mid 70s to lower 80s.
