Event narrative

Flash flooding reported in downtown Tyler.

Wider weather episode

Numerous thunderstorms developed along and ahead of a persistent MCS in East Texas during the afternoon of June 11th. Thunderstorms began training ahead of the MCS, and the overlapping segments of heavy rainfall resulted in scattered flash flooding across parts of Smith County and Harrison County. Hourly rainfall rates within this activity were estimated at nearly 3 inches per hour. The uptick in convective coverage and intensity was due to the thunderstorms training along a NW-SE oriented instability axis characterized by 1000-3000 J/kg MLCAPE, 2-2.25 inch precipitable water values, and 20-30 knots of southwesterly effective shear amid a variety of convergence boundaries analyzed across the region. As a result, flash flooding occurred in the more urban locations of Tyler in Smith County and near Marshall in Harrison County.
