Today will feature the development of a dynamic storm system right along the Maine coast, which will result in a diverse mix of weather across the area. Because conditions will vary so much by area, see the paragraph with info for your subregion for details on what to expect.
Along the coast, heavy rain will fall with the chance for thunderstorms through midday. That heavy rain will change over to heavy snow a little later this afternoon for areas west of route one. Accumulations will range from a dusting at best east of rt1 to 1-3″ between route 1 and the turnpike. Temps will generally hover in the low to mid 30’s.
Inland, morning freezing rain will change over to snow. This process will happen generally from west to east. As snow takes over, expect quick accumulations as heavy banding dumps 1-3″ per hour. A general 3-6″ can be expected here, with lighter amounts closer to the coast. Temps will remain locked in the lower 30’s. Watch out for very slick surfaces (roads/driveways/sidewalks) as snow falls on top of ice that fell last night!
In the mountains, we got a lot of snow coming! Heavy bands are working their way up the mountain chain from Sunday River to Sugarloaf, and it’ll be dumping 1-3″ per hour for most of the day today as that band stalls and pivots. An additional 6-12″ are expected, with more in the higher terrain. Temps here will drift downwards from the low 30’s this morning into the upper 20’s by tonight.
The storm wraps up from SW to NE tonight with cold NW winds and upslope snow showers continuing into tomorrow.
