From the WABI-TV5 & CW Forecast Center:
The combination of strong ridge of high pressure to our west and a storm near Newfoundland produced a brisk and cold northwesterly wind all across Maine today. The northwest wind helped pull a modified arctic airmass south through New England today and this pattern will continue tonight and tomorrow. Low temps tonight will fall into the teens to very low 20s, with high temps tomorrow ranging from the mid to upper 20s north to mid 30s south.
The large high will move east towards Mid-Atlantic Coastline Thursday and Friday. A southwest breeze on the backside of the high will gradually bring milder air back to Maine Thursday through Saturday. High temps Thursday will range from the upper 30s north to the mid 40s south, with temps both Friday and Saturday reaching the mid 40s to very low 50s. The high will keep conditions dry in our area right through much of the weekend. A storm passing up to the west of New England later Sunday night or Monday will help pull milder air into our region on an increasing southerly breeze. The storms trailing cold front will move east and bring the risk for showers to Maine Monday and Tuesday.
Tonight: Partly to mostly clear, breezy and cold, with high temps in the teens to near 20s.
Wednesday: Mostly to partly sunny, breezy and cold, with high temps in the mid 20s to mid 30s from north to south.
Thursday: More sun than clouds, with high temps in the upper 30s to mid 40s.
Friday: Partly sunny, with high temps in the 40s to low 50s.
Saturday: Partly sunny, with high temps in the 40s to low 50s.
Sunday: Partly sunny and mild, with high temps in the mid 40s to low 50s.
Monday: Mostly cloudy, with possible showers and high temps in the upper 40s and 50s.
