Mesoscale Discussion 0799

1150 PM CDT Tue May 19 2026

Areas affected...from the Laredo area eastward toward the middle to
upper Texas Coast

Concerning...Severe Thunderstorm Watch 233...

Valid 200450Z - 200615Z

The severe weather threat for Severe Thunderstorm Watch 233
continues.

SUMMARY...Isolated wind gusts over 50 kt remain possible across
parts of southern into southeast Texas, within the broader zone of
30-40 kt outflow.

DISCUSSION...Within a broad W-E zone of thunderstorms, a few wind
gusts over 50 kt have been measured, most recently at Kerrville TX
with 56 kt. While most of the outflow as produced gusts of 30-40 kt,
several larger/more organized storm clusters exist near intersecting
outflow boundaries. The air mass remains quite moist, with modest
southerly winds just above the surface aiding inflow (elevated above
the outflow in some cases).

At this time it appears the overall severe risk will remain isolated
across the entire region, with most gusts below 50 kt. However,
trends will continue to be monitored as the system as a whole
develops southeastward tonight.
