From the WABI-TV5 & CW Forecast Center:
A slow moving and intensifying storm system both at the surface and aloft will move southeast through New England Saturday and early Sunday. The storm will bring occasional showers to Maine both weekend days, with the bulk of the showers falling Saturday afternoon and night. The combination of mostly cloudy skies, occasional showers and an onshore breeze will keep the temperatures in our region running below normal both weekend days.
The storm system will slowly drift southeast off the New England coastline later Sunday through Tuesday, while at the same time strong high pressure building south from the Hudson Bay region will begin to control the weather conditions across Maine. The high will bring generally fair and breezy weather to Maine Monday through Wednesday, with temperatures running several degrees below normal Monday, but slowly moderating back to more seasonable levels by mid-week. Another slow moving storm will approach New England from the southwest late next week allowing showers to return to Maine either Thursday or Friday.
Tonight: Increasing clouds, with low temps in the low to mid 30s.
Saturday: Thickening clouds, with scattered showers spreading from west to east and high temps in the mid 40 to low 50s.
Sunday: Variably cloudy and breezy, with a few more scattered showers and high temps in the mid 40s to mid 50s.
Monday: Partly sunny, blustery and cool, with high temps in the mid 40s to low 50s.
Tuesday: More sun than clouds, breezy and still cool, with high temps in the upper 40s to mid 50s.
Wednesday: More clouds than sun, with high temps in the 50s to near 60, coolest near the coastline.
