An upper level low and remnant MCVs produced several rounds of heavy rain and training storms that produced flash flooding for a few day across the region, mainly 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.

Flash Flood — Sep 6, 2025
Tropical Storm Lorena's remnants, a late-summer cold front, and an upper-level trough collectively contributed to significant thunderstorm activity across North Texas during the afternoon and evening of September 5th and into the morning of September 6th. Several of these storms generated damaging wind gusts and hail, while frequent cloud-to-ground lightning resulted in multiple residential fires.
