EF1 tornado in Baltimore County, Maryland

After exiting the City of Baltimore, a tornado moved through northern portions of the Dundalk Historic District causing significant roof and siding damage to several homes and apartments. One of the more significant damage points in this area was a large portion of roofing that was removed from a row of apartments and thrown towards the east-southeast into the next row of apartments. The tornado then continued towards the east-southeast towards Merritt Boulevard. The neighborhood just west of Merritt Boulevard received extensive damage, both structurally and to trees. Many of the trees had their middle and upper branches snapped off. The most significant damage in this neighborhood was to a home's roof that was lofted from the west side of Sunberry Road onto Merritt Boulevard. The homeowner noted that he witnessed debris being carried through the air right before his roof was removed. Beyond this point, the tornado continued briefly towards the east-southeast towards Stansbury Park. There was some damage in the neighborhood east of Merritt Boulevard that remained consistent with a tornado, particularly a wooden utility pole that had been bent over, but not snapped. Damage beyond this point became unidirectional, providing evidence that the tornado likely lifted around Stansbury Park at 6:01 PM EDT, as the rear-flank downdraft winds undercut the circulation leading to straight-line wind damage towards the east.

A line of thunderstorms developed over western Maryland and eastern West Virginia, then significantly gathered strength as it moved east into the I-95 corridor. Destructive winds, very large hail, and a tornado were observed with some of the most intense storms. Additional thunderstorms in a weakening but still severe state crossed the Appalachians overnight.
