A cold front that brought severe weather to the Midwest and the Mississippi Valley Thursday was crossing the Atlantic Coast states Friday producing heavy rain, locally gusty thunderstorms and travel disruptions.

As the rain and storms push eastward from the Appalachians to the coast, travel delays will also become more extensive especially in the swath from New York City to Philadelphia, Washington, D.C., Charlotte and Atlanta during the evening hours Friday.

The storms could also disrupt evening ballgames.

While the intensity of the thunderstorms will depend to some extent on the timing (day versus night) and on how warm locations remain, most places from Florida to Maine will at least get a period of drenching rain accompanied by some wind.

The storms and downpours are expected to increase in strength due to the building warmth of the afternoon and then remain strong into the evening.

Spotty showers will occur ahead of the line of storms.

A prevailing cool wedge of air and/or clouds may limit the intensity of the storms over central and eastern New England.

A couple of the strongest storms could produce a tornado.

Some locations can be hit by more than just a downpour and some lightning and thunder. A few places can have a severe thunderstorm that brings strong winds, torrential downpours and hail. As a result, there is the potential for downed trees, power outages and flash flooding in the vicinity of the storms.

According to Severe Weather Expert Henry Margusity, "The greatest chance of severe weather and a few tornadoes stretches from southeastern Pennsylvania to coastal South Carolina from into the evening."

The storms are the remnants of a squall line that affected the Central states with severe thunderstorms and flooding during the middle of the week.

The storms will hold off until the overnight and early Saturday morning hours before they reach the east coast of New England.

There is the potential for 1-2 inches of rain along a large part of the Atlantic Seaboard later Friday and Friday night.

Much cooler and drier air will sweep in over much of the Eastern states this weekend. However, showers and thunderstorms may linger over central and South Florida. Spotty showers are likely over the central and northern Appalachians and eastern Great Lakes. Wet snowflakes could mix in over the highest elevations of northern Pennsylvania and upstate New York Saturday.
