Freezing Rain Slowly Changes to Rain Today

Hello everyone!

A strong storm is once again advancing through the Great Lakes this morning which puts us once again on the wrong (warm) side of the circulation. Precipitation is moving in from the west this morning in the form of freezing rain/sleet away from the NH Seacoast where temps are warm enough for rain. The general idea is that everyone but the immediate shoreline will start off with enough ice to make travel slick this morning before the freezing line creeps slowly inland this afternoon.

With cold air damming setups like this, the safe money is on a slower-than-modeled transition from mixed precip to rain, and today appears to be no exception. With that in mind, I think the I-95 corridor probably won’t get above freezing until the early afternoon while the foothills likely retain subfreezing air and ice until the cold front approaches overnight. Total ice accretion amounts appear to range from a trace near the coast (still enough for slick travel!) to about 1/4″ in the foothills. That isn’t quite power outage territory, but as winds pick up overnight, a few folks could see the lights go out especially in the foothills.

Drier air will return for tomorrow.
