From the WABI-TV5 & CW Forecast Center:
A trough of low pressure out ahead of a cold front will bring scattered showers and storms to Maine this evening and night. Not everyone will see the showers and storms, but some of the storms this evening will be strong to severe and contain a strong and gusty wind, torrential downpours, hail and frequent dangerous lightning. The locals most likely to see strong to severe storms tonight will be located to the north and west of the Bangor Region. Low temps tonight will run in the low to mid 60s.
The cold front currently moving through the Eastern Great Lakes Region will move through New England tomorrow. Once again numerous showers and thundershowers will develop as the cold front crosses Maine during the day. Some of the storms tomorrow will likely be strong to severe and contain a strong and gusty wind, along with heavy downpours, hail and frequent dangerous lightning. Once again a southerly breeze ahead of the cold front will keep conditions humid Tuesday, with high temps ranging from the mid 70s to low 80s throughout Maine.
A northwest breeze behind the cold front will usher a cooler and less humid airmass into New England later Tuesday night and Wednesday. An upper level trough crossing New England Wednesday will keep the risk of showers going across the Pine Tree State, with northern parts of the state seeing the bulk of the showers. 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. 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 may move into the Northeast over the weekend and bring a windswept rain to much of New England.
Tonight: Partly to mostly cloudy, scattered showers and thundershowers, with some of the thunderstorms containing a strong and gusty wind, hail and torrential downpours, with low temps in the low to mid 60s.
Tuesday: Partly to mostly cloudy and humid, with scattered showers and thunderstorms, with a gusty wind and hail in any of the stronger storms, with high temps in the mid 70s to low 80s.
Wednesday: Variably cloudy, with scattered showers 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 to mid 70s, from north to south.
Saturday: Partly sunny then increasing clouds, with high temps in the upper 60s and 70s.
