Flash Flood — Jun 30, 2025
Widespread strong-to-severe thunderstorms developed along a quasi-stationary boundary across central and southern Oklahoma and western-north Texas during the evening of the 30th. In addition to a measured severe-caliber wind gust, the combination of high moisture content in the lower atmosphere and slow-moving thunderstorms led to a few localized areas of flash flooding across southern Oklahoma.
Flash Flood — Apr 29, 2025
Multiple rounds of severe convection and flooding occurred from the predawn hours of the 29th into morning hours of the 30th. The most significant round of severe thunderstorm activity occurred across portions of western-north Texas on the evening of the 29th, where intense supercell thunderstorms produced very large hail, damaging wind gusts and a pair of significant (EF-2+) tornadoes. Signifi...
Flash Flood — Apr 26, 2025
A slow-moving mesoscale convective vortex (MCV) produced severe weather and flash flooding during the morning and afternoon of the 26th. An initial complex of thunderstorms across southwestern Oklahoma and western-north Texas produced reports of thunderstorm wind damage and large hail, especially with a supercell thunderstorm that moved near the city of Lawton. Areas of persistent heavy rainfal...
Flash Flood — May 2, 2025
Numerous severe thunderstorms impacted portions of central and southern Oklahoma and western-north Texas early on the morning of the 2nd. Synoptically, this convective episode was driven by the approach of a weak shortwave trough rounding the periphery of a broader upper system across the Central and Northern Plains. Very strong elevated instability and sufficient wind shear promoted organized ...
Flash Flood — Apr 30, 2024
A rather nebulous upper air pattern existed across the Southern Plains on the 30th, with 30-40 knots of quasi-zonal flow at 500 mb. However, plentiful solar insolation/surface heating in the vicinity of a dryline fostered widely scattered thunderstorm development by the late afternoon. Strong instability and sufficient organizing wind shear lead to a few of these storms displaying supercellular...
