From the WABI-TV5 & CW Forecast Center:
After a prolonged period of milder than normal temps the conditions across our region will be turning cooler over the next several days. A cold front slipping through New England this evening will bring an end to the scattered showers across Maine and skies will begin to clear out after midnight. A northwest breeze on the backside of the cold front will begin to usher a chillier airmass into our area late tonight, with low temps falling into the 30s by daybreak tomorrow.
A new storm will develop off the Mid-Atlantic Coastline later tonight and early Wednesday morning. The storm will likely track well southeast of New England late tomorrow and that should keep the bulk of the storm precipitation well off to our east. The western fringe of the storms rain shield may clip far eastern Maine with a few showers during the evening hours tomorrow, with just a few clouds from the storm moving into other parts of the state.
As the storm moves up to our northeast Wednesday night a gusty wind will usher an even cooler airmass into the Pine Tree State for the rest of the workweek and the beginning of the weekend. A large dome of high pressure will bring generally fair skies to go along with the chilly temps Thursday through Saturday. A storm moving east from the Great Lakes Region will produce a round of showers in Maine later Saturday night and Sunday morning, with a few snowflakes possibly mixed with the rain over northern parts of the state.
Tonight: Scattered showers ending then becoming partly to mostly clear, with low temps in the 30s.
Wednesday: Partly cloudy, possible scattered showers east late and cooler, with high temps in the mid 40s to low 50s.
Thursday: Partly sunny, breezy and cool, with high temps in the 40s to near 50.
Friday: Partly cloudy and cool, with high temps in the 40s.
Saturday: Partly sunny then increasing clouds late, with high temps in the 40s to near 50.
Sunday: Showers likely possibly mixed with wet snow north and high temps in the 40s to near 50.
