We are beginning to transition to what will be a very stormy pattern setting up for the weekend
Today one storm system is developing over the Plains, this system will head ENE tracking through the interior Northeast tomorrow bringing showers and periods rain for Friday mostly in the afternoon, with a southerly wind ahead of the system temperatures will moderate big time into the mid 50s to low 60s, scattered showers will continue into the evening but gradually breaking up as the night goes on and it should be mostly dry for a good chunk of the area from later Friday night through Saturday morning besides southern areas.
The cold front will stall just south of the area, and a storm will develop along this front over the SE US which will use the stalled frontal boundary just off the coast as a train track, the storm will gradually intensify coming up the coast pulling in Gulf and Atlantic moisture, steady rain will fill in gradually from south – southeast to north-northwest as the coastal storm moves northeast , the rain will quickly become moderate to heavy with increasing east- northeast winds.
The details become a bit sketchy after this although a bit more clear today, as the storm has a good chance of lingering over the coastal waters through Sunday and possibly even into Monday with rain and wind lingering especially over coastal areas , with prolonged easterly flow coastal flooding could become a issue but this will depend on where exactly the storm cuts off and lingers
Either way very hefty rainfall totals and perhaps flooding will be a end result
Over the next few days we will have to iron out the exact track to see if the heavy rain axis shifts either west or east , but just west of the storm track will be the heaviest rain axis where 3-5 inches of rain can be expected, right now this is most likely to occur east of the Delaware river and especially closer to the coast , but this track and thus zone will probably shift around and plus for interior areas of higher elevation prolonged easterly wind could enhance rainfall due to topographic lifting.
