Midcoast Forecast - October 23, 2018

An area of low pressure is moving in from the west that will bring soaking rain to Midcoast Maine Tuesday afternoon and through the night with snow across northern Maine. Rain will begin to change to snow further south as temperatures drop into Wednesday morning. With temperatures below freezing aloft but near or above freezing at the surface, snowflakes may be observed near the coast but have difficulty accumulating while higher elevations will see light accumulations. Exact totals will depend on exactly how cold temperatures become into Wednesday morning. A trace to 2" will be possible for inland locations across southern Maine with higher amounts north and into the western Maine mountains.

Skies will gradually clear late Wednesday and into Thursday as high pressure builds in from the west. This will set up over the region for the late week returning the Midcoast to mostly sunny skies but usher in cold and brisk weather. The north to northwest winds will lead to building seas Wednesday and stay choppy through the late week. Overnight lows will drop into the 20s with afternoon highs in the 40s.

An area of low pressure will move up the east coast on Saturday pushing clouds into the Midcoast during the morning with precipitation arriving during the late afternoon and evening. With cold air in place, precipitation may start as a winter mix before changing to all rain as milder air moves in through Saturday night. The storm will intensify into a classic nor'easter as it move into New England with strong east to northeast winds which could gust up to 50mph during the overnight. Rain and windy conditions will continue into Sunday morning before tapering off through the day and into Monday.
