From the WABI-TV5 & CW Forecast Center:
High pressure will produce another pleasant day across New England today as it slowly moves east through our area. High temps across Maine will generally climb into the 60s, but slightly cooler air over Quebec will drift into far northern parts of the state and hold temps there in the upper 50s.
High pressure will slowly slip off to our east Friday and that will allow clouds to gradually build back into our region after a partly to mostly start. High temps Friday will likely climb into the mid 50s at the coastline to the low to mid 60s over interior parts of Maine, with the warmest temps being found over northern parts of the state. Showers ahead of an approaching warm front may move into western parts of Maine later Friday afternoon, but the bulk of the showers will likely hold off until Friday night and Saturday.
A storm moving east from Ontario into Quebec will likely push a warm front through New England Saturday. The warm front will produce a period of showers throughout Maine as it crosses the Pine Tree State. If the warm front slides through Maine during the morning hours the afternoon temps will likely climb into the mid 60s to near 70, otherwise temps will hold in the 50s to low 60s. Mother’s day will likely become partly sunny, with a west to southwest breeze on the backside of the departing storm allowing temps to climb into mid 60s to mid 70s across the Pine Tree State. Monday will likely turn out partly cloudy and mild, with a round of scattered showers likely popping up as a cold front approaches New England from the north.
Today: More sun than clouds, with high temps in the upper 50s across the far north and 60s elsewhere.
Friday: Partly sunny then increasing clouds, with high temps in the mid 50s to mid 60s.
Saturday: Mostly cloudy, with showers likely and high temps in the 60s.
Sunday: Partly sunny and mild, with widely scattered showers possible and high temps in the mid 60s to mid 70s from north to south.
Monday: Partly cloudy, with possible scattered showers and high temps in the 60s to low 70s.
