Thunderstorm Wind in Marion County, Texas

Numerous trees and power lines downed in Jefferson.

Regenerative thunderstorm development occurred during the afternoon on April 28th across Central Texas along existing outflows from an MCS that decayed earlier in the morning. Surface temperatures continued to warm into the upper 70s to lower 80s within cloud breaks south and east of the large-scale outflow boundary across East Texas. This led to moderate buoyancy with upper 60s to lower 70s surface dew points. Upscale growth continued along the regenerating MCS as it propagated farther east across the Ark-La-Tex early into the evening. With a favorable deep layer wind profile (0-6km shear near 50 knots), supercells were possible within any emerging thunderstorm clusters. Meanwhile, the leading edge of a surging bow echo resulted in widespread damaging winds with a mature squall line along with an isolated report of large hail. Given the expanding heavy rain shield and cold pool, a few reports of flash flooding were also recorded.
