Outlook:

The incoming “slop” system, that will begin wintry for some had raised some winter weather advisories I’m these area highlighted below

The snow aspect of the event is not long lived. Quick initial thump and the vertical temp profile gradually warms aloft and to the surface.

Right along the west edge of those expected better early snow accumulations should be a sleet zone, and some areas of freezing rain before the Tuesday pm features plain rain. The Blue Knob and those higher eastern Allegheny PA areas should hold on to the wintry aspect the longest. As the midday model runs illustrate

A quick look at the 12z ECMWF

The next story looks to be the strong southeast winds. Those come over the Alleghenies and downslope west has a good potential to cause some power outages.

Wind gust in excess of 50+mph possible. Wind Advisories and High Wind Warnings in play.

A look on the models at the winds, and wind direction. Winds from the southeast Tuesday then often right ahead of the wind direction flip there is some lull, but don’t let your guard down as Wednesday a.m will feature strong SW winds and in this case those are ushering back the colder air

A look at the 12z HRRR winds from the Ventusky website. Advancing every several hours.

Temps tomorrow on those SE winds hold cold through the a.m hours in those typical wedge areas in the over running events. Eventually enough moist, and just mild enough air works in to flip things to plain rain area wide.

All told this system has plenty of moisture. 1-2″ of total liquid and in some areas upwards .75 to a inch could be in the frozen form. Then plenty of moisture remains to fall on that. Areas that are primarily all rain stand a chance at some localized creek flooding, and high water likely across the entire region once everyone changes over

Those amounts include what is a portion of frozen precipitation.

As we progress Tuesday night in to Wednesday we end as some upslope snow to end the event and that looks to progress through very rapidly and amounts should be rather light on the order of 1-2″ that will be blown about as things refreeze back over.
