As mentioned yesterday, a coastal storm is expected to develop along the Delmarva coast Thursday through Friday as a result of two impulses merging and phasing.  A blocking pattern in the Atlantic will cause this storm to linger from Thursday into Friday and then slowly move eastward.  Rain with windy conditions is expected with a possible mix in of wet snow Friday morning with little if any accumulation.

The latest models have this storm becoming a sort of impressive “superstorm” far off the coast on Saturday;  other than windy conditions here and some significant maritime/ coastal issues, this superstorm won’t be a concern in PHL.   This would change if intensification occurs earlier than forecast, but not expected at this time.
