Thunderstorm Wind in Morris County, Texas

Numerous trees downed in and around the Rocky Branch community with vehicles stalled on roadways because of all the downed trees blocking lanes.

A large cluster of strong to severe thunderstorms developed across Northeast Texas late in the afternoon on April 26th. These thunderstorms formed on the north side of a weak surface theta-e gradient, with southwest winds just off the surface aiding in warm air advection and inflow across the region. This cluster of thunderstorms maintained severe intensity for several hours with numerous reports of large hail and damaging winds as the the core of the low-level jet moved overhead. Farther west along the surface dryline, additional thunderstorm development in this area became increasingly displaced from the low-level jet through the evening but still resided in a region of unstable air, with steep mid-level lapse rates and strong deep layer shear. As a result, a few reports of flash flooding also resulted from training thunderstorms across parts of Northeast Texas.
