Today will feature heavy rain and snow depending on your location. Right along the coast, a coastal front has developed over the midcoast, York County, and just west of Portland. Winds to the east of the CF are out of the east and will be keeping these areas 100% rain throughout the day. Across Northern Casco Bay and interior areas though, Cold Air Damming is locked in place with cold NNE winds keeping cold dry air readily available. In these areas, any raindrops first thing this morning will quickly turn to snow.
As for snowfall accumulations, check the map below.
Snow/rain is arriving currently from SW to NE and will linger through midmorning tomorrow especially in the north.
Highs will range from 32 in the mountains to 45 east of the Coastal Front.
