From the WABI-TV5 & CW Forecast Center:
Our generally quiet and pleasant weather pattern will continue all across Maine the next several days. A cold front will slip south through the state today. A north/northwest breeze behind the cold front will usher a cooler and less humid airmass into our region today and lasting through Friday. It’ll still be warmer than normal today but as the cold front crosses the state during the day the humidity levels will begin to drop rather quickly. A stray shower/thunderstorm or two may pop-up as the cold front slides across Maine today but otherwise it will be partly to mostly sunny.
As high pressure build down towards New England from southern Ontario Friday a northerly breeze on the east side of the high will usher a cooler airmass into New England as high temps run in the low to mid 70s, which is normal for this time of year.
The holiday weekend looks very pleasant as the ridge of high pressure just northwest of Maine Friday builds just to the south of New England as the holiday weekend moves along. A southwest breeze on the backside of the high will once again pull a warmer and somewhat more humid airmass into Maine as we head through the holiday weekend. High temps Saturday will climb up into the upper 70s to low 80s, but then continue to warm Sunday and Labor Day, with temps Sunday in the low to mid 80s and even a few degrees warmer on Labor Day.
High pressure will continue to control the weather in our area Tuesday and likely Wednesday as it remains anchored off the Mid-Atlantic Coastline. A southwest breeze on the backside of the high will continue to draw warm and humid air into our region as we head through the middle of the workweek. An approaching cold front will bring an increased risk of scattered showers and thundershowers to Maine later Wednesday and Thursday, with cooler and less humid air arriving in New England by Friday.
Today: Partly to mostly sunny, warm and becoming lass humid, with a slight chance of a shower or thunderstorm. High temps in the upper 70s to mid 80s. North wind 5-10 MPH.
Friday: Partly sunny and cooler, with high temps in the low to mid 70s from north to south.
Saturday: Mostly sunny and warmer, with high temps in the upper 70s to low 80s.
