From the WABI-TV5 & CW Forecast Center:
The on and off showers across much of Maine the last day and a half are associated with a storm that continues to slowly develop off the Delmarva Coastline. Rainfall rates in our region will increase tonight and tomorrow as the storm begins to lift north, with the rain continuing right into Friday morning as the slow moving Nor’easter lifts north along the Mid-Atlantic Coastline tomorrow and then rides northeast through the Gulf of Maine tomorrow night and early Friday.
As the storm crawls up the coastline the next several days the pressure gradient between a strong ridge of high to our north and the intensifying storm to our south will cause the wind across New England to increase, with the wind likely gusting over 40 mph, especially along the coastline later tonight and tomorrow. The prolonged gusty northeast wind will cause the waves to build along the coastline to between 7 to 11 feet over the next couple of days and that will likely lead to minor beach erosion. The combination of rain and a gusty northeast breeze will make it feel rather raw tonight and tomorrow.
Conditions will slowly begin to improve later Friday as the storm drifts up into the Canadian Maritimes. A very weak ridge of high pressure will pass by to our south Saturday which should allow at least a little partial sunshine to develop across southern and central Maine, with still a few showers possible, mostly up north. An upper low along with a new cold front riding southeast from central Canada will likely bring another round of showers to our region Sunday. High pressure approaching New England from the west will likely produce partly sunny skies in our region both Monday and Tuesday.
Tonight: Breezy, with periods of showers, heavy at times and low temps in the upper 30s to mid 40s.
Thursday: Periods of rain, heavy at times and blustery, with high temps in the upper 40s to mid 50s.
Friday: Mostly cloudy, with showers tapering off and high temps in the 50s.
Saturday: Variably cloudy, with a few scattered showers possible and high temps in the 50s.
Sunday: Mostly cloudy, with scattered showers and high temps in the upper 40s to mid 50s.
Monday: Partly sunny, with high temps in the upper 40s to mid 50s.
