Midcoast Forecast - November 26, 2018

Clouds have been locked in place Monday as our next storm system moves into the region. A broad area of low pressure is exiting the Great Lakes Monday afternoon and will move into New England Monday night and into Tuesday pushing in heavy rain and snow to Maine. Precipitation will start around midnight with rain along the immediate coast and snow inland with the rain line gradually pushing in through Tuesday morning as milder air moves in from the Gulf of Maine. Locations south of I-95 should all change over to rain by sunrise Tuesday morning, melting any new snow accumulation seen during the overnight hours. Rain will continue through the morning then gradually taper off from south to north during the early afternoon as dry air pulls into the system. The storm will slow and stall briefly over New England Tuesday night and into Wednesday that will continue to bring rain and snow mix to central Maine with all snow north and just occasional rain showers for the Midcoast through Wednesday. The storm will then slowly exit east Wednesday night and into Thursday that will keep clouds locked in with continued pockets of rain and snow into Thursday. Rainfall will range either side of 1" along the coast with increasing snowfall amounts the further north you go (see map). Summits of the western Maine mountains and New Hampshire could see up to 2 feet of new snow.

This storm will also bring strong wind to the Midcoast especially for south and east facing shorelines. East to southeast winds will gradually increase Monday night and peak Tuesday morning with sustained winds between 20 to 30mph with gusts up to 45mph possible. Winds offshore could gust as high as 50kts (~57mph) which will build seas up to 14 feet Monday night and into Tuesday morning. A Storm Warning is in effect through Tuesday morning because of this. Penobscot Bay could see seas up to 5 feet. Winds will decrease and switch out of the southwest Tuesday afternoon and into the overnight with light west winds on Wednesday.

We'll see sunshine briefly return on Friday before more clouds move in for the weekend with spotty showers possible Saturday followed by a stronger rain storm on Sunday.
