Mesoscale Precipitation Discussion 0227
NWS Weather Prediction Center College Park MD
500 PM EDT Sun May 24 2026

Areas affected...Dallas-Forth Worth Metro

Concerning...Heavy rainfall...Flash flooding possible

Valid 242100Z - 250200Z

SUMMARY...Localized flash flooding over the greater Dallas-Fort
Worth metro into this evening from slow moving heavy thunderstorms
producing up to 4" rainfall.

DISCUSSION...As of 21Z...thunderstorm clusters north of Ft. Worth
and southeast of Dallas have developed in a moist/unstable
environment. Instability is typical for North Texas summertime
convection with SBCAPE around 3000 J/kg as is moisture with PW
around 1.5" and dew points in the upper 60s. Light flow will
continue to allow slow movement and popcorn type convection
developing off outflow boundaries. Rainfall rates up to 2"/hr
estimated by KFWS in the past hour should generally hold true for
subsequent convection through the evening. There is a risk for
some repeating convection/cell mergers which could allow localized
4" totals which would be a concern for flash flooding, especially
in the broad urbanized areas of the metro.

Recent HRRR runs are underestimating the ongoing activity and
generally underplay the heavy rainfall threat for this metro area
into this evening. Hail is a concern with this activity, but
enough rainfall should occur to cause localized flash flood
concerns into the evening. Further thunderstorm development to the
south may warrant additional discussions in Texas through this
evening.
