Major Storm Coastal Flooding, Heavy Rains & Snow Northeast Pennsylvania & New Jersey
Much of the action will occur north of South Central Pennsylvania and North Central Maryland with this weather system but we will see a chilly rain out of this and there is a chance for a hlaf inch to an inch of rain out of this. There is a High Wind Watch up for North Central Maryland. To our north and east, watch warning map is lit up like a Christmas tree.
Low pressure heading into the Ohio will hit that huge blocking high to the north and be forced to redevelop rapidly off the Delaware Coast. The rapid development of the coastal low will create stormy conditions Friday and Friday night from Southern New England to the Delaware coast. Rain will be heavy and then comes the complication of strong upper air dynamics creating cold air. This means the rain will change over to wet snow in many areas. The question of where and how much snow however remain very difficult at this point. Certainly elevated areas in Northern New Jersey, Northeastern Pennsylvania and the Hudson Valley west of the Hudson River could see heavy snow and some amounts in these areas could be rather excessive. Even areas in Western & Southwest New Jersey could see a slushy few inches if dynamics set up in a certain way. Areas to the east of NYC will have to deal with warm air getting swept in westward from off the ocean to some degree which may overcome the cold strong upper air dynamics. However even in these areas it could be quite the struggle.
