From the WABI-TV5 & CW Forecast Center:
Showers have been slowly developing in the Gulf of Maine and then rotating back into our region today as an upper level low to our southwest moves towards the Mid-Atlantic Coastline. The energetic upper low is currently helping develop a new surface low just off the Mid-Atlantic Coastline, which will be intensifying tonight and tomorrow as it meanders to the south of New England.
The combination of high pressure parked over Central Quebec and the intensifying storm system along of the Mid-Atlantic Coastline will combine to bring a prolonged period of rain and wind to our region. Rain showers will slowly become a steadier rain tonight, especially from the Lincoln and Dover-Foxcroft regions on southward. The rain will continue to fall across Maine tomorrow and Thursday as winds both at the surface and aloft continue to pull moisture into New England from the Atlantic Ocean. At times the rain will fall heavily throughout the Pine Tree State, beginning later tomorrow and likely continuing right into Friday morning. By the time the rain taper off later Friday much of our area will have received between 2 and 4”, with possibly a bit more over some of the hillier locations of Maine.
As the storm crawls up the coastline the next several days the pressure gradient between the high to our north and intensifying storm to our south will cause the wind across New England to increase, with the wind likely gusting over 30 mph beginning late tonight night and continuing through Thursday. The prolonged gusty northeast wind will cause the waves to build along the coastline to between 8 to 12 feet by later tomorrow and that will likely lead to minor beach erosion. At the time of high tides splash over along the coastline could lead to some minor flooding along the shoreline. The combination of rain and a gusty northeast breeze will make it feel rather raw the next several days.
Conditions will slowly begin to improve later Friday as the storm drifts up into the Canadian Maritimes. A weak ridge of high pressure will build into the Northeast Saturday which should allow at least some partial sunshine to develop across Maine. An upper low along with a new cold front riding southeast from central Canada will likely bring scattered showers back to our region Sunday.
Tonight: Becoming blustery, with showers slowly spreading north and low temps in the upper 30s north and 40s south.
Wednesday: Blustery, with periods of rain and high temps in the upper 40s to mid 50s.
Thursday: Periods of heavy rain, heavy at times and blustery, with high temps in the 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 a few scattered showers and high temps in the upper 40s to mid 50s.
