From the WABI-TV5 & CW Forecast Center:
The storm system that brought the chilly rain to Maine today continues to slide east across New England. As the storm exits to our east this evening the showers will taper off and end, with some partial clearing late tonight. Low temps tonight in our area will range from the mid 30s north to the low 40s south.
A ridge of high pressure currently building southeast from Hudson Bay will control the weather across Maine Saturday through Monday. An active 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 mid 40s north to the low and mid 50s around the Bangor Region despite a good deal of sunshine. The high will keep the our weather partly sunny Sunday over southern parts of Maine, while a warm front sliding east across northern parts of the state will keep skies mostly cloudy north of the Bangor region, with even a few scattered showers falling over the far northern regions of the state. High temps Sunday will range from the low 50s up north to the low 60s from the Bangor region on south.
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 mid 60s to low 70s throughout Maine, which is over ten degrees above normal. The high should keep the skies partly to mostly sunny all across New England Monday. An approaching cold front from the west along with a storm lifting north off the Mid-Atlantic Coastline will combine to bring an increased risk of showers to the Pine Tree State Tuesday into early Wednesday. As the front slips off to our east a shot of somewhat cooler air will filter into New England for the end of the workweek.
As we head into next weekend and beyond it appears an upper level trough will begin to develop over the Northeastern States and that should lead to a cooler and somewhat unsettled pattern for the second half of October. It may turn cool enough by later next weekend and on into the following week that some of the precipitation that falls across Maine falls as snow, especially over the higher elevations.
Tonight: Showers ending, partial clearing late, with a northwest breeze around 10 mph and low temps in the mid 30s to low 40s.
Saturday: Partly to mostly sunny and breezy, with high temps in the mid 40s north to mid 50s south.
Saturday night: Mostly clear early then increasing clouds late, with a light wind and low temps in the upper 20s to mid 30s.
Sunday: Partly sunny south and mostly cloudy north, with high temps in the low 50s to low 60s from north to south.
Monday: Partly to mostly sunny and mild, with high temps in the 60s to low 70s.
Tuesday: Variably cloudy, with possible scattered showers developing and high temps in the 60s.
Wednesday: Partly sunny, with high temps in the 50s to near 60.
