We will start off with light rain/drizzle overspreading the area tomorrow morning and late afternoon especially the farther north you go, the rain will become steady and heavier. Eventually tomorrow night once the cold front passes through the rain will change to brief snow before ending.
With the track of the storm areas from central/ southern NJ to LI will be put in the warm sector of the storm with very windy southerly winds developing ahead of the storm tomorrow afternoon with, these areas may not get much steady rain but instead have the best shot of getting strong thunderstorms with the cold front that will approach tomorrow late afternoon with a potential squall line , areas north of these areas will see more of a steady rain with more of a isolated storm threat, the heaviest and steadiest rain will be NW NJ and NE PA , there could be isolated flooding in areas with snow pack.
With a rapidly intensifying low moving through between 980-985 mb, very strong NW winds can be expected as the storm pulls away.
Arctic air will filter in behind it with temperatures rapidly falling through the 20s and brutal wind chills through Thursday
