From the WABI-TV5 & CW Forecast Center:
High pressure will continue to control the conditions here today. The high will continue to slowly drift off the northeastern U.S. coastline today and that in combination with a slowly moving front approaching New England from the west will turn the wind across Maine into the southeast Tuesday. The southeast wind will keep the temps in coastal towns in the mid 60s to low 70s, while areas well away from the coast reach the mid 70s to near 80.
A storm aloft and the slowly approaching cold front will bring mostly cloudy skies to Maine Wednesday, with an increased risk of showers as the day moves along. High temps Wednesday will range from the very low 60s at the shoreline to the low 70s well inland. The upper low and frontal system will very slowly cross the Northeast Thursday and Friday and that will cause occasional showers to fall throughout New England both days. 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 the upper low moves northeast through the Canadian Maritimes and high pressure both at the surface and aloft begins to build into the Northeast. Skies Saturday will likely average out 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 to our region Sunday along with slowly warming temps.
Today: Partly to mostly sunny, with high temps in mid to upper 60s at the coastline to the 70s to near 80 well inland.
Wednesday: More clouds than sun, with scattered showers likely and high temps in the 60s to very low 70s.
Thursday: Mostly cloudy, with occasional showers likely 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.
