From the WABI-TV5 & CW Forecast Center:
The bubble of high pressure that has produced the partly to mostly sunny skies across Maine the past few days will slowly settle off to the south of New England tonight and tomorrow. A milder airmass will filter into Maine tonight and Wednesday as temps tonight hold in the 40s, with highs tomorrow running in the 60s to near 70. A rather moisture starved cold front will slide through the Pine Tree State later tomorrow afternoon, with just a few clouds over our area and maybe a few light showers across northern parts of Maine.
As winds kick around into the northwest behind the cold front a cooler airmass will slide into Maine Thursday. High temperatures in Maine Thursday will range from the low 50s north to the mid to upper 50s south despite a good deal of sunshine. A storm and cold front moving east through the Great Lakes Region Thursday will likely bring a period of rain showers to Maine Friday, with the bulk of the showers in our area falling during the afternoon and evening hours. High pressure building east across Quebec will bring partly to mostly sunny skies to Maine Saturday. A brisk northwest breeze on the eastside of the high will usher a rather cool airmass into Northern New England Saturday as highs across Maine range from the upper 40s north to the mid 50s around the Bangor Region. The high will keep the our weather partly sunny Sunday with temps running in the 50s to near 60, which is just a few degrees below normal for this time of year.
As the high slips off to our south a southwest breeze will usher milder air into New England for Columbus Day Monday as highs climb into the 60s to near 70 throughout Maine under partly sunny skies. A cold front will bring the risk of a few showers to the Pine Tree State Tuesday followed by some cooler air for the middle and end of next week.
