From the WABI-TV5 & CW Forecast Center:
The scattered showers and thundershowers that popped up today are associated with a cold front and an upper level trough currently swinging southeast into New England. The steadiest showers and storms tonight will be located to the north and west of the coastline, with the bulk of the activity tapering off during the evening hours. Most if not all of the showers should have ended by daybreak on Saturday as the front continues to weaken and the upper level disturbance passes off to our southeast. High pressure centered to the north and west of New England should bring improving conditions to our region Saturday as skies turn partly then mostly sunny, with high temps ranging from the low 60s at the coastline to the upper 60s to low 70s over interior Maine.
The ridge of high pressure moving into the Northeast will bring sunny skies and mild temps to all of the Pine Tree State Sunday. The high will produce fair skies throughout Maine on Monday as well, but an approaching weak cold front might kick off some scattered showers up north towards evening. On Tuesday our region will see variably cloudy skies along with a few scattered showers as the weak front to our north slips into Northern New England. Temperatures Sunday and Monday will top off in the 70s, with the coolest readings being found near the coastline. The combination of more clouds and an onshore breeze will hold temps in the 60s to near 70 Tuesday.
Tonight: Scattered showers and storms tapering off, then mostly to partly cloudy, with low temps in the 40s.
Saturday: Partly to mostly sunny, with high temps in the low 60s at the coastline to the upper 60s to very low 70s inland.
Sunday: Mostly sunny and milder, with high temps in the low to mid 70s.
Monday: Partly sunny, with high temps in the 70s.
Tuesday: Variably cloudy, with a few scattered showers possible and high temps in 60s to low 70s.
Wednesday: More clouds than sun, with scattered showers likely and high temps in the 60s.
