“The stormy weather will not just interfere with outdoor plans, it will slow travel.”

While a storm system continues to crawl across the East, thunderstorms will rumble across portions of the mid-Atlantic and Southeast over the next couple of days.

The storm system will inch across Pennsylvania today. Storms will develop from Connecticut and the New York City metropolitan area westward to Ohio and southward through the Carolinas this afternoon and evening.

A few of the thunderstorms may turn strong, especially near the mid-Atlantic and Southeast Coast, where the most humid air will be in supply. The strongest storms could produce hail and strong winds. However, there is not expected to be as much energy in place as recent days for a widespread or organized severe thunderstorm outbreak.

Sporadic incidents of flash flooding are possible, especially in poor drainage areas and in communities where the soil is already saturated from recent days.

Dangerous cloud-to-ground lightning strikes will occur even in areas where thunderstorms do not become strong. If you hear thunder, then you should head indoors for shelter.

The stormy weather will not just interfere with outdoor plans, it will slow travel at times across the Northeast. Flights could be delayed at major airports, including in New York City, Philadelphia, and Washington, D.C.

Heavy rain from the thunderstorms will also slow traffic on the ground. Motorists who travel along I-64, I-76, I-80, I-81, I-84, and I-95 may run into suddenly and significantly rain-reduced visibility.

Along the storm’s cold front, thunderstorms will ignite across central and South Florida. Localized damaging winds and downpours are a possibility with these thunderstorms. Fort Myers will get hit by some thunderstorms, and stormy weather will spread to Miami during the afternoon hours.

On Monday, a new round of thunderstorms will spark from Alabama to southeastern New York. Again, widespread severe weather is not anticipated, but people should keep alert to watches and warnings since a few thunderstorms may become more violent.

To the north, localized flooding may be a concern with days of rainy weather ahead. AccuWeather.com Senior Meteorologist Kristina Pydynowski discusses the steadier and soaking rain that will fall across parts of the Northeast.
