Our region is under a slight risk for severe weather for Saturday with the approaching cool front that will bring another Taste of Fall into the region. I'm not overly bullish on the prospects for severe weather but I do think a round of wind and rain, perhaps some thunder, is in the cards on Saturday evening as the front comes through.
First, the timing for the front is Saturday evening -- most of Saturday should be ok to decent weatherwise as skies will be variably cloudy to even mostly sunny at times. It will be warmer than past days as temperatures get into the lower or even middle 80's (south of the city for the warmer temperatures). The front crosses the region between 6 and 9 PM in the west, hitting the coast between 11 PM and 2 AM. You'll get a good chunk of Saturday in without dodging drops, especially in New Jersey and Delaware. Southeastern Pennsylvania might have a few showers to deal with ahead of the front but odds favor dry into the afternoon.
In terms of rainfall totals from tomorrow's front, most people get a half inch or less from it. There could be some localized higher totals to the north of the city that could yield some localized ponding of water on roads given it mostly comes with the front itself. It should not as big an event as Tuesday's storm, though.
