Severe Weather Risk Augusta, Ga. to Augusta, Maine

During Tuesday, there is the potential for thunderstorms with locally damaging winds and torrential rain as a Southern system rolls northeastward ahead of an advancing push of cool air.

In localized areas, winds from the storms can be strong enough to break off tree limbs and cause power outages. In some cases, trees could be toppled and more significant property damage is possible. Some locations may be blasted by small hail as well.
In many cases the event will be only marked by a period of very heavy, windswept rain.
The storms would sweep eastward from Tuesday into Tuesday night in most areas from northern Florida and Georgia to New England.

The storms are likely to organize within or ahead of a broad zone of heavy rain extending across the Appalachians. The rain would also advance to the I-95 corridor in the Northeast and can lead to major travel problems for a time.
 
Storms from central and northeastern North Carolina to southeastern Pennsylvania and New Jersey can be especially robust with high winds and hail. If discrete storms form in front of the advancing heavy rain, just the right setup could yield a tornado. The timing for such storms would be Tuesday midday and afternoon.

Meanwhile, in the South, a trailing disturbance in the upper atmosphere could produce a few discrete, intense thunderstorms from the Florida northeastern Gulf Coast to central Georgia and South Carolina. The timing for the storms that brings the risk of a couple of tornadoes to the South is Tuesday midday into Tuesday evening and would take advantage of daytime heating.

Dry air would push in from the west ending the severe weather threat in the southern and middle Atlantic coasts Tuesday night. The risk of severe weather would not occur in New England until Tuesday night. The storms would not clear eastern Maine until the first thing Wednesday morning.
