The potential exists for a widespread severe weather outbreak spanning from the St. Lawrence Valley and interior Northeast down into the Appalachians and Tennessee Valley later today and tonight.
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 to close out the weekend.
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 will come together today to help trigger potentially 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 middle Mississippi 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 will provide plenty of instability to support storms throughout the day.
Lines of dangerous thunderstorms are expected to produce damaging winds in excess of 60 mph as well as torrential downpours. Hail to the size of pin-pong balls will also be possible, especially from the Ohio Valley south into the middle Mississippi Valley.
Although the threat is low, an isolated tornado or two cannot be completely ruled out at this point. Those at greatest risk are towns and cities across Upstate New York, southern Ontario, and the St. Lawrence Valley.
Toronto, Buffalo, Cleveland, Louisville and Memphis will be the first in line today for severe weather. The storms will track toward the east into Montreal, Syracuse, Pittsburgh and Nashville later on in the afternoon.
The storms will impact the final round of the WGC Bridgestone Invitational being played at Firestone Country Club in Akron, Ohio, as well as the Pro Football Hall of Fame pre-game festivities down Interstate 77 in Canton. The weather should cooperate just in time for the preseason kick-off between the New Orleans Saints and Arizona Cardinals at Fawcett Stadium.
Later this evening and tonight, the strong storms will push into the bigger cities in the Northeast and mid-Atlantic. Boston, New York and Washington, D.C., will all be at risk.
Storms are expected to decrease in intensity as we head throughout the overnight hours.
In the wake of this system, less humid and pleasant air will filter into the Northeast and mid-Atlantic for the early part of the week.
