Thunderstorm Wind in District of Columbia, District of Columbia

Dozens of trees, branches and wires blew down in Columbia Heights, Petworth, Fort Totten, Michigan Park, University Heights, Brookland, Brentwood, and Trinidad. A large tree blew down onto a residence on Queen Street Northeast, displacing a dozen residents.

A strong cold front intersected a very hot, humid, and unstable airmass across the Mid-Atlantic shortly after peak heating. Aided by dynamics and moderately strong shear from an approaching upper-level trough, the front spawned bands of thunderstorms that produced considerable wind damage particularly in the I-95 corridor. Some areas saw the worst thunderstorm-driven wind speeds and damage since the derecho in June 2012, though the area affected by the highest magnitude of winds was not nearly as large.
