After heavy storms overnight in the Philadelphia area, the sun returned, and now we’ve generated plenty of fuel for thunderstorms this afternoon. This is incredibly humid weather with dew points in the upper 70s.
Get your outdoor activities done early, as showers and storms will return by late afternoon and early evening, bringing heavy rain, frequent lightning, and winds gusting to 60 mph or higher. The Storm Prediction Center has placed most of the region in a Slight Risk (2/5) for severe thunderstorms, with damaging wind gusts as the main threat.
Alongside the severe threat, there’s also a risk of localized flash flooding. Potential rainfall values between 2.0-2.5 inches and deep warm cloud layers will support heavy rainfall rates, especially if storms persist over the same area. Delmarva is under a Slight Risk (2/4) for excessive rainfall, with a Marginal Risk (1/4) elsewhere.
The National Weather Service has issued a severe thunderstorm watch until 9 p.m. Tuesday for the Philadelphia region.
A flood watch is also in effect for most of the region beginning at 2 p.m. This morning, the National Water Prediction Service was already reporting minor flooding along the Brandywine Creek in Downingtown and in Honeybrook.
