From the WABI-TV5 & CW Forecast Center:
High pressure center northwest of New England will bring sunshine and pleasant conditions to Maine Saturday. Under mostly sunny skies the temps will climb into the 50s to near 60 during the afternoon, which is just a couple degrees below normal for the last day of April. With the high nearby the wind will be rather light Saturday and that will allow the wind to turn onshore along the coastline during the afternoon which will keep coastal towns cooler than inland locations.
On Sunday conditions will start out dry, but a developing trough to our southwest will slide up into New England and that may lead to some late day showers across Maine, especially to the west of the Bangor Region. The storm system associated with the developing trough will move east from the middle of the country Sunday and then slide northeast from the Mid-Atlantic Coastline Monday. Scattered showers will likely become more of a light steady rain as the storm slides to the southeast of New England Monday. Showers may linger over northern parts of Maine part of Tuesday as the storm system slides up into the Canadian Maritimes. Weak high pressure will bring fair weather to Maine later Tuesday into much of Wednesday, but a large upper level storm will likely develop along the East Coast later next week, with periods of much needed rain likely developing in our area late Wednesday or early Thursday.
Saturday: More sun than clouds, with high temps in the 50s to near 60.
Saturday night: Clear early then increasing clouds late, with low temps in the 30s.
Sunday: Increasing clouds, with possible afternoon and evening showers and high temps in the 50s to near 60.
Monday: Showers likely, breezy and cool, with high temps in the mid 40s to low 50s.
Tuesday: Variably cloudy, with lingering showers north ending and high temps in the 50s to near 60.
Wednesday: Partly sunny then increasing clouds, with possible late day showers and high temps in the mid 50s to low 60s.
