From the WABI-TV5 & CW Forecast Center:
A storm moving east from Ontario into Quebec will pull the warm front through New England Saturday morning. The warm front will produce occasional showers throughout Maine as it crosses the Pine Tree State. As the warm front lifts off to our northeast the wind will shift into the southwest and temps will likely climb up into the 60s to near 70 Saturday afternoon. A trailing cold front will keep the risk of showers, with even a few thunderstorms possibly firing up across Maine later in the day, with most of the showers ending during the evening as the cold front slips off to our east.
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 backdoor cold front approaches New England from the Canadian Maritimes. If the cold front to our north slips south through Maine earlier in the day than is currently expected temperatures will not be as mild as currently forecasted. A northeast breeze will develop once the cold front settles to our south and that will lead to cooler temps in our region for the middle of the workweek.
Saturday: Mostly cloudy to partly sunny, with occasional showers and possible thundershowers and high temps in the 60s to near 70.
Saturday night: Variably cloudy, with scattered showers and low temps in the mid 40s to low 50s.
Sunday: Partly sunny and mild, with widely scattered showers possible and high temps in the low 60s to low 70s from north to south.
Monday: Partly cloudy, with possible scattered showers and high temps in the 60s to low 70s.
Tuesday: Variably cloudy, few scattered showers possible and high temps in the mid 50s to mid 60s.
