Update, 7:30 PM. As the line of storms pushes through the region, showers will linger back to the west. However, the threat for severe weather will largely be eliminated as the line pushes northeast and north through the region. Rainfall has been rather heavy within the band as it lifts northeast, totaling between a third and three quarters of an inch within an hour's time. Rainfall behind this initial band will not be quite as heavy, with showers and areas of light rain likely to continue through the evening.
As of 6 PM we have the disturbance responsible for the heavy rain and thunderstorms that have developed this afternoon is centered over Pennsylvania. It's working east and northeast, with thunderstorms firing across our region south into Delaware and South Jersey. All of this is pushing north and northeast, with heavy downpours occurring in these thunderstorms.
While severe weather has not occurred locally as of yet, the potential for a severe warning or two cannot be ruled out this evening. With wind shear a bit of an issue in parts of Pennsylvania, an isolated tornado or downburst cannot be ruled out in thunderstorms across Pennsylvania...which is why the tornado watch is out across the region as we work into the evening hours.
The plan for this evening is to see heavy rain and thunderstorms, especially west and northwest of the city, through the evening. Farther east and southeast will see some storms but it may take a while longer for them to push to the Shore thanks to the seabreeze in place along the coast. Where thunderstorms are heavy, localized flooding cannot be ruled out...neither can gusty winds.
