   CORRECTED TEXT

   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, stronger 2-hourly surface pressure
   rises in excess of 4 mb have become evident in the 04Z surface
   observations at Uvalde and Junction.  Additionally, 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.
