Well here's the thing... Globals overall have not held onto the structure of the oncoming short wave into confluence zone in NYS New England so have been depressed. 6z EC topped in favor of the 06-09z RRSFA, RAP, NAM3K and 12z HRRR.
I sure hope the 12z/18 HRRR is not that far wrong... it could be too aggressive to the north but I expect a 2-4" stripe somewhere near I80 which would be a little south of the 12z HRRR axis. Uncertainty of course but we have to make decisions on what we do.
So potentially embarrassing if it fails but this is what I updated locally.
Updating I84 corridor 9AM. Plowing will probably be needed for at least the higher elevations tomorrow morning from northeast PA through nw NJ/se NYS into at least southern CT and possibly Hartford Ashford. Too much short term modeling that is at the leading edge of mesoscale modeling is upping amounts and predicting a decent 5 hour event that will require adjusted traveling times.
Entire I84 region from the Poconos across nw NJ, se NYS into ag least the southern two thirds of CT 1AM-9AM Wednesday (tomorrow) morning. A 3-6 hour period of wet snow that likely accumulates 1-4"-especially grass. Valley roads 600 feet or below just wet because of temps just above freezing but accumulations on untreated pavements expected for the hills where the temp will drop to 30, especially 1000 feet or higher. The northern extent of the snow shield is a little uncertain but prepare for slower travel-delays in your early Wednesday morning travel. In my opinion there is an increasing chance of a 2 hour delay for high terrain schools I80 northward. Overall
