From the WABI-TV5 & CW Forecast Center:
A storm in the upper levels of the atmosphere slowing moving east across southern Ontario and Quebec will continue to control the weather across Maine today. The upper level low and its associated pool of cool air aloft will keep the atmosphere over northern New England rather unstable, leading to skies ranging from partly to mostly cloudy with a few scattered showers popping-up from time to time. The bulk of the showers will likely fall over the north and mountains.
A cold front will slide east across New England tomorrow causing the shower activity to become a bit more numerous throughout the Pine Tree State. The combination of mostly cloudy skies and scattered showers will hold the temps in the upper 60s to low 70s in our region. A disturbance aloft slipping southeast from Quebec later Sunday night and Monday morning may also kick off a few scattered showers in Maine, with the bulk of the showers falling across northern parts of the state. Temps Monday will once again run a bit below normal as highs hold in the upper 60s to mid 70s from north to south.
A ridge of high pressure will build into the Northeast Tuesday bringing New England a brighter sky. The combination of more sunshine and a milder airmass will help temps climb back up to more seasonable levels by Tuesday as highs reach the mid 70s to near 80. The high will bring mostly sunny skies to Maine Wednesday, with high temps ranging from the mid 70s to low 80s.
Today: Partly to mostly cloudy, with scattered showers and high temps in the upper 60s to mid 70s.
Tonight: Partly to mostly cloudy, with a few scattered showers and low temps in the 50s.
Sunday: Mostly cloudy with scattered showers and high temps in mid 60s to low 70s.
Monday: Partly cloudy, with a few showers possible north and high temps in the upper 60s to mid 70s.
Tuesday: More sun than clouds, with high temps in the 70s to near 80.
Wednesday: More sun than clouds, with high temps in the mid 70s to low 80s.
