From the WABI-TV5 & CW Forecast Center:
An upper level area of low pressure drifting east through the Gulf of Maine and its associated pool of cool air aloft kept conditions a bit unstable across New England yesterday as brief hit and miss showers kept popping up across our region. The upper low and the pool of chilly air aloft will bring one more unstable day weather-wise to Maine today as pop-up showers develop with the heating of the sun. Temps today will run a few degrees below normal for early May as highs hold in the 50s to low 60s throughout the Pine Tree State.
High pressure both at the surface and aloft will slowly build into the New England Wednesday and Thursday and bring brighter and milder conditions to our region. Under partly to mostly sunny skies the temps Wednesday will climb into the low to mid 60s. The atmosphere will continue to slowly warm under mostly sunny skies Thursday as high temps climb into the 60s to near 70. The high will slowly slip off to our east Friday and that will allow clouds to gradually build back into our region. High temps Friday will likely climb into the 60s, with an afternoon seabreeze likely keeping temps coolest along the coastline. A storm moving east through the Great Lakes region will likely bring rain showers and cooler temps to Maine as we start the weekend Saturday.
Today: Variably cloudy with a few scattered showers possible and high temps in the mid 50s to low 60s.
Wednesday: Partly to mostly sunny, with high temps in the lows to mid 60s.
Thursday: More sun than clouds, with high temps in the 60s to near 70.
Friday: Partly sunny then increasing clouds, with high temps in the low to mid 60s.
Saturday: Mostly cloudy, with showers likely and high temps in the 50s.
