Violent thunderstorms will take aim from the Dakotas and Nebraska to New York and Pennsylvania this evening and Saturday.

Many locations that were damaged by thunderstorms that produced tornadoes and flash flooding Wednesday and Thursday will once again be threatened by additional powerful storms tonight and Saturday.

Damaging wind gusts and flooding rainfall are of high concern from any storms developing across an area stretching from the northern Plains through the Midwest and into portions of New York, Pennsylvania and perhaps New Jersey through tonight.


Similar to Thursday, several tornadoes could also be spawned from the strongest of storms.

Locations that could get these severe storms tonight include Sioux Falls, S.D.; Minneapolis, Minn.; Des Moines, Iowa; Chicago, Ill.; Cleveland, Ohio; and State College, Pa.

Widespread flooding, produced by slow-moving thunderstorms Thursday evening, is ongoing in many locations across the Midwest, specifically southern Wisconsin, which received upwards of 8 inches of rain in only a few hours.

The threat for additional flooding will only be amplified by these storms, which could easily drop several more inches of rain over a very short period of time.

Motorists should be alert for blinding downpours and should never drive through flooded roadways.

Additional strong storms are expected to develop again during the day on Saturday, mainly along an axis from western Kansas east through the Chicagoland area and into portions of western New York and Pennsylvania.


Elsewhere, thunderstorms are expected across the Southeast into Saturday. Heavy, gusty thunderstorms from Bonnie will move off the shore of Florida late tonight but onshore over the Florida Panhandle to the Louisiana Delta area later Saturday.

Thunderstorms will also fire this evening along the higher elevations of the central and southern Rockies and across the desert states.
