Following Friday's deadly super derecho, another round of nasty thunderstorms will threaten parts of the Midwest and mid-Atlantic into Saturday evening.
Friday's super derecho, a widespread and long-lived violent thunderstorm complex, left a trail of destruction and power outages from northern Indiana to the southern mid-Atlantic coast.
Many of the same areas which were affected on Friday will have to endure yet another round of gusty thunderstorms into this evening. While clusters of violent thunderstorms will develop, another far-reaching land hurricane is not expected.
Locations which could be impacted this afternoon include Charleston, W. Va., Baltimore, Md., Washington, D.C., Dover, Del., and Richmond, Va.
The danger also extends back to central Illinois, including the city of Champaign.
Similar to Friday's storms, very damaging winds will be the primary threat. Hail and even an isolated tornado are also possible with the strongest storms.
In most cases, winds will be upwards of 50-60 mph into this evening. The strongest storms will be capable of producing winds in excess of 70 mph.
Winds of this magnitude will easily be capable of bringing down trees and power lines, especially trees weakened during Friday's severe weather. Those with loose outdoor furniture are advised to bring them indoors or properly secure them to the ground.
The blazing heat and humidity ahead of these storms will once again help fuel these powerful storms as they track towards the south and east.
The severe weather threat will end by late tonight, but yet another round of thunderstorms will rattle the Midwest and mid-Atlantic to close out the weekend.
Tropical Depression Seven strengthened into Tropical Storm Gaston during Monday night with another system attempting to form near the Caribbean.
