   Areas affected...southeastern Missouri/southern Illinois

   Concerning...Severe Thunderstorm Watch 364...

   Valid 100809Z - 101015Z

   The severe weather threat for Severe Thunderstorm Watch 364
   continues.

   SUMMARY...Local risk for gusty/damaging winds continues across WW
   364.

   DISCUSSION...Latest radar loop shows near-continuous line of strong
   storms moving southeastward across southeastern Missouri and
   adjacent southern Illinois at around 30 kt.  Ahead of the storms, an
   airmass featuring 1000 to 1500 J/kg mixed-layer CAPE persists, which
   should allow convection to persist as it advances steadily
   southeastward.  While the latest PAH WSR-88D VWP data shows only
   moderate (AOB 30 kt) flow through the lower half of the troposphere,
   a few stronger gusts remain possible given the still-organized
   nature of the convective band.
