Tuesday/Wednesday Nor’easter

This one will have many variables including heavy snow, heavy rain, wind, and flooding. Some communities may experience some snow showers and flurries overnight. Most of that will be ocean effect, and shouldn’t be a big deal. The bulk of our precipitation should arrive on Tuesday. Temperatures will be cold enough for light snow and freezing rain early in the day. Coastal areas should expect a change to rain during the mid-day through afternoon while inland towns experience a change from snow to freezing rain. The mountains will hold onto snow/sleet through the evening and there heavy snow is likely. A Winter Storm Warning has been issued there.
Warning

Heaviest rainfall for the coastal plain will be afternoon through the first half of the night. A Flood Watch has been issued.
