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.

Heaviest rainfall for the coastal plain will be afternoon through the first half of the night. A Flood Watch has been issued.
In addition winds will increase out of the NE to E gusting over 40 mph. A Wind Advisory has been issued for coastal Maine and New Hampshire.
The storm will be a very slow mover hanging around for a few days, but the worst will be afternoon and evening Tuesday. Periods of rain are likely on Wednesday followed by rain and snow showers late week.

Timing:  Some light ocean effect snow or sleet showers will likely arrive tonight into tomorrow morning.  Steadier precip from our storm arrives late morning to around lunch.
Precip Type:  We start with snow then change to sleet, freezing rain, and then rain.  First to see the change over is the coast which happens quickly, inland towns take longer to change over to rain but should by the evening hours.  The mountains stay snow and sleet right through the day tomorrow and into the overnight hours.

Snow/ Sleet Amounts: 
Snowfall amounts will range from a coating at the coast to a couple of inches of accumulation inland.  The mountains will see the most with more than a foot for some areas.
Rainfall Amounts:  2 to 3″ of rain is possible for southern and central areas which could lead to some street flooding.
Freezing Rain Amounts: A light coating of ice is likely coastal plain before the change over to plain rain.  In the valleys within some of the foothills there may be more significant icing into tomorrow night. We will keeping an eye on that possibility.
Wind:   Winds will be gusty tomorrow afternoon and tomorrow night with gusts to 40 mph likely especially along the coast.
Power Outages:  The combination of snow, ice, and gusty winds will likely lead to some power outages (esp. inland and mountains).
