From the WABI-TV5 & CW Forecast Center:
The large dome of high pressure both at the surface and aloft that brought the sunny and pleasant weather to Maine today will continue to bring bright skies and mild temps to our area tomorrow. Low temps tonight will fall into the 40s and then highs tomorrow will reach well up into the 70s, with the coolest readings being found along the coastline as the wind turns light onshore.
The high will continue to control the weather across Maine Friday and part of Saturday as it slowly moves east off the Mid-Atlantic Coastline. A southerly breeze both Friday and Saturday will keep the temps along the coastline cooler than inland spots. Highs temps Friday will range from the upper 60s in some coastal towns to the 70s over much of interior Maine. A bit more cloud cover and an increasing southerly breeze will keep the temps across our region a bit cooler Saturday than they will be Friday.
After a partly sunny start to the day an approaching cold front will bring increasing clouds to New England later Saturday. The cold front will produce scattered showers in our region beginning later Saturday night or early Sunday, with the showers likely continuing across Maine until the front slips offshore later Sunday evening. High pressure approaching from the west will bring cooler and drier air back into New England as the workweek begins on Monday.
Tonight: Clear and cool, with low temps in the 40s.
Thursday: Mostly sunny, with high temps in the 70s, coolest at the shoreline.
Friday: Mostly to partly sunny, with high temps in the upper 60s at the coast to the 70s inland.
Saturday: Partly sunny start then increasing clouds, with high temps in the mid 60s to low 70s.
Sunday: Mostly cloudy, scattered showers likely, with high temps in the 60s.
Monday: Partly sunny and cooler, with high temps in the upper 50s north and 60s south.
