From the WABI-TV5 & CW Forecast Center:
A slow moving cold front will bring mostly cloudy skies to Maine today with an increased risk of showers as the day moves along. High temps will range from the upper 50s at the coastline to the 60s inland this afternoon. An upper level low pressure system along with the cold front will very slowly cross the Northeast Thursday and Friday and that will cause periods of showers to fall throughout New England both days. A surface storm developing along the approaching cold front may allow a period of heavier rain to develop across Maine beginning later Thursday night and continuing into early Friday mainly along the coast. The combination of clouds, showers and an onshore breeze will help hold high temps in the 60s both Thursday and Friday.
Weather conditions across New England should gradually improve as we head into the weekend as both the upper and surface lows move northeast through the Canadian Maritimes and high pressure begins to build into the Northeast. Skies Saturday will turn partly cloudy, with just the chance of a few widely scattered showers falling, mostly across northern parts of Maine. The high will likely bring mostly sunny skies too our region Sunday along with slowly warming temps. High temps Saturday will likely climb back up into the 70s to near 80, with highs Sunday reaching the upper 70s to low 80s.
Today: Mostly cloudy, with scattered showers likely and high temps in the upper 50s to mid 60s.
Thursday: Mostly cloudy, with periods of showers and high temps in the 60s.
Friday: Mostly cloudy, with occasional showers likely and high temps in the 60s.
Saturday: Partly sunny, with a few widely scattered showers possible and high temps in the 70s to near 80.
Sunday: Mostly sunny and warm, with high temps in the upper 70s to low 80s.
