Today's Bout of Thunder

Today's round of showers and storms brought a lengthy list of hail, wind, and flooding reports throughout the Delaware Valley.   The storms developed around midday in South Jersey and lifted slowly north-northwestward towards the city.

By 12:45, those storms were gaining in number and becoming stronger.  At this point, they were situated near Vineland and Hammonton.

Over the next hour, the coverage of the storms increased through the region as they lifted north and northwest.  Storms became severe during the 1 PM hour as wind gusts to over 50 miles per hour dropped from the storms...along with hail as large as an inch.  The strongest of storms tracked through Burlington, Philadelphia, Mercer, and Bucks Counties as it lifted north and northwest.  In addition to the gusty winds and hail, rainfall rates of over an inch per hour accompanied the storms as they lifted through.

The storms weakened somewhat on the western flank after passing through Philadelphia but still produced some rather robust wind and heavy rain as they lifted through the northern and western burbs...however, the brunt of the action passed through Bucks County and Mercer County between 2 and 3 PM.

Radar estimates in this area exceeded an inch from Allentown down through Bucks County into Trenton, south to Hammonton.  However, other areas fared quite well from a rainfall standpoint.  Philadelphia picked up 0.87" of rain during the 2 PM hour and Allentown also picked up over a half an inch.

Thunderstorm activity is again possible tomorrow but we shouldn't see as widespread a band move through as we saw today.  Activity should be a bit more scattered in nature across the region.
