Battered-and-bruised residents across the Mid-Atlantic, Appalachian Spine, and Mid-South into parts of the Carolinas will face additional clusters of powerful thunderstorms tonight and early on Monday. Not only will a few tornadoes be possible, but very large hail and high winds will be possible as well.
A few clusters of potent thunderstorms with a destructive wind history continue to plow across West Virginia and southeastern Pennsylvania tonight. An even more dangerous punch of thunderstorms will also continue to roll across southeastern Kentucky, eastern Tennessee, and western North Carolina this evening and tonight.
The severe weather in the Mid-Atlantic is being driven by an unusually potent upper-level disturbance tracking across Pennsylvania into very warm and humid air. Eventually, these two areas of dangerous severe weather across Pennsylvania and West Virginia will merge into early Monday morning, flinging fresh thunderstorms all the way into the Interstate 95 corridor from the Nation's Capital to Philadelphia.
Further south, wave-after-wave of powerful thunderstorms has slid quickly from eastern Kentucky into western North Carolina thus far today. Unfortunately, yet another cluster organizing ahead of a cold front dividing very warm and humid air from cooler and drier air in the wake of the front will allow the thunderstorms to march all the way into Upstate South Carolina tonight and on Monday morning.
In addition to a few brief tornadoes will be high winds ranging from 65 to 75 mph and large hail peaking near baseball-size. Knoxville, Tenn., Asheville and Charlotte, N.C., Greenville-Spartanburg, S.C., and the Nation's Capital to Philadelphia and State College, Pa., will all need to keep a watchful eye to the sky for threatening thunderstorms.
Tornado Watches extend from northeastern Ohio and western Pennsylvania to western North Carolina, including Pittsburgh, Jackson, Ky., Knoxville, Tenn., and Asheville and Charlotte, N.C. A Severe Thunderstorm Watch is in place across much of Pennsylvania, far western New Jersey, and from the West Virginia Panhandle into northwestern Maryland, including State College, Pa.
Drenching rain will be part of the thunderstorms repertoire as well. Flash Flood Watches and Flood Watches are in effect from southern Ohio into western New York. As much as 3 inches of rain falling in a short time could cause flash flooding concerns here. This will be especially true where storm drains are overwhelmed or blocked by debris. Remember, if you approach a flooded roadway, it is best to "Turn Around, Don't Drown."
As the severe weather builds across the Eastern U.S. tonight, the reports are mounting as well. Thus far today, a total of 246 severe weather reports have been documented, with softball-to-grapefruit sized hail pelting Bear Branch, Ky., earlier this afternoon. Meanwhile, a 70-mph gust was clocked across Bloomfield Hills, Mich., while trees and power lines have been knocked down or toppled from Wisconsin to North Carolina and Massachusetts.
