Areas affected...parts of Deep South Texas

Concerning...Severe Thunderstorm Watch 407...

Valid 110425Z - 110530Z

The severe weather threat for Severe Thunderstorm Watch 407
continues.

SUMMARY...The risk for severe wind gusts may across and southwest
through south of the Greater San Antonio vicinity through Midnight-1
AM CDT.

DISCUSSION...Cold pool propagation into the I-35 corridor near and
south of San Antonio has been at rather modest speeds of 20 kt or
so, and peak 3-second gusts along the gust front have recently been
measured around 40 kts. However, the most vigorous convection only
slightly trails the gust front, and is becoming better organized,
with a meso-beta scale cyclonic circulation now forming to the west
of San Antonio. This may be accompanied by strengthening westerly
rear inflow and downdrafts, aided by heavy precipitation loading,
near and to the southwest through south of Greater San Antonio
through 05-06Z.
