Severe Storm Watch Philly, North, and West Until 10 PM


A Severe Thunderstorm Watch is out until 10 PM for Philly, Southeastern Pennsylvania, the Lehigh Valley, and points north from there.  South Jersey, Trenton, and Delaware are not included in the watch.

The watch was issued due to this line of thunderstorms that extends from Williamsport southwest into Virginia, tracking east and northeast.  Storms have had a tendency of producing damaging wind over the past several hours across the Appalachians as they have marched steadily along.  The storms themselves are in a broken line...you can see some breaks within the line as they approach Harrisburg and York.


Gusty winds are possible with the storms as they move towards us, perhaps some gusts over 50 mph in spots. The best chances for those will reside to the northwest and north of us (Allentown, Poconos, Scranton) where the strongest storms are projected to track.  We can't completely rule out a strong or severe storm here but the strongest section of the line is tracking north of the region.

Timing these out -- it looks like they get into Reading after 6, into Allentown and Pottstown after 6:45, into Philadelphia around or after 8 PM or so.

Storms may push through South Jersey and Delaware as well but odds favor these weakening enough to where the threat of severe weather will be low after 8 PM.
