Severe thunderstorms are firing from New York state through Tennessee, with damaging wind gusts being the biggest threat. Storms will be most intense through this evening before diminishing in intensity overnight.

The same storm system which brought rounds of severe weather from the Dakotas to the western Great Lakes and middle Mississippi Valley Friday and Saturday will again be the main culprit for this severe weather outbreak.

The unusually potent disturbance by early August standards will impact millions of people as it blows through the heavily populated cities in the East.

All the necessary atmospheric ingredients are coming together to help trigger dangerous thunderstorms.

The focus of the strongest thunderstorms will be along the cold front as it passes through eastern Canada, the eastern Great Lakes and the Tennessee Valley.

Out ahead of the front, very warm and moist air will be abundant all the way to the East Coast. With just a little bit of heating from the sun, the air mass is providing plenty of instability to support storms into the first half of tonight.

According to Meteorologist Matt Alto, "lines of dangerous thunderstorms are developing and they will be capable of producing damaging winds in excess of 60 mph as well as torrential downpours. Hail to the size of ping-pong balls will also be possible, especially from the Ohio Valley south into the Tennessee Valley."

Binghamton, Albany, Washington D.C., Scranton and Harrisburg will be the first in line this afternoon and evening for severe weather. The storms will track toward the east into New York City, Philadelphia, Dover and Atlantic City late this evening and tonight.
