Flash Flood — Jul 13, 2025
Several rounds of showers and thunderstorms occurred the weekend of July 12, influenced by remnant outflow boundaries, a stalled front, and a slow-moving upper low. A mesoscale convective vortex (MCV) further enhanced precipitation totals and rain rates, resulting in flash flooding primarily across Central Texas.
Flash Flood — Jul 7, 2025
From the July 4th weekend into the early part of the following week, a weak upper trough lingered over North and Central Texas, triggering several days of scattered showers and thunderstorms. A saturated atmosphere combined with slow storm motions resulted in numerous flash flooding events throughout the region, particularly in Central Texas.
Flash Flood — May 1, 2025
An upper level disturbance dropping southeast through the Plains led to thunderstorm development on May 1st and 2nd across much of North and Central Texas. Storm initiation occurred in the vicinity of remnant outflow boundaries left over from the previous nights' convection. Some severe thunderstorms occurred, mainly in Central Texas, with large hail the primary severe weather occurrence.
Flash Flood — May 22, 2024
Isolated thunderstorms associated with the dryline occurred on May 21. Much more widespread thunderstorm activity took place on May 22 as a cold front sagged south into the area and a strong jet stream developed aloft. Large hail, damaging winds, and flash flooding affected several locations on the 22nd. An EF2 tornado occurred in the Temple area of Central Texas, causing significant damage and...
Flash Flood — Sep 4, 2020
An upper level trough moved very slowly from the Rockies into the Plains during the first week of September, resulting in several days of showers and thunderstorms. Many storms became strong with gusty winds and hail, but the primary result was heavy rain and flooding. Unfortunately, a couple died in Temple Texas in a house fire that was started by lightning.
