The wider storm
Numerous thunderstorms developed along and ahead of a persistent MCS in Northwest Louisiana 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 Shreveport in southern Caddo Parish. 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. In addition to the flash flooding in Caddo Parish, isolated damaging wind gusts were reported in Grant Parish and Union Parish with trees downed in a few locations.
Began near Downsville (32.6300, -92.4100).
