The storms then moved into Philadelphia, the surrounding Pennsylvania suburbs, South Jersey and Delaware late Thursday night.
Severe Storm Threat

After pockets of steady rain Thursday morning, some scattered showers continued during the day.
Scattered showers continued into prime trick-or-treating time Thursday night.
With temps in the 70s in many neighborhoods, trick-or-treaters didn't need a warm coat over their costume though raincoats and ponchos were recommended.
Winds kicked up in the late afternoon and early evening and were quite gusty as leaves and loose fitting costumes blew around.
Once Storms Move Out, Cold Temps Remain for the Weekend
The gusty winds from the Halloween system will sweep the clouds and storms out of the area early Friday morning and bring in much chillier air.
The highs on Friday, Saturday and Sunday are expected to be in the 50s. Lows in the Lehigh Valley, Pennsylvania suburbs and interior South Jersey could drop to below freezing by Monday morning.
