   Areas affected...Missouri...Far Western Illinois

   Concerning...Tornado Watch 192...194...

   Valid 070729Z - 070930Z

   The severe weather threat for Tornado Watch 192, 194 continues.

   SUMMARY...A potential for wind damage, a few tornadoes, and hail
   will continue along a line of strong to severe storms moving through
   Missouri. The severe threat will eventually affect parts of western
   Illinois later tonight.

   DISCUSSION...The latest hi-resolution radar imagery shows a
   well-developed severe linear MCS, with several embedded rotating
   cells and bowing line segments. This line is moving eastward into
   moderate instability, with the RAP analyzing MLCAPE around 1500 J/kg
   across much of eastern Missouri. In addition, WSR-88D VWPs ahead of
   the line near St Louis have 0-6 km shear near 35 knots, with 0-3 km
   storm-relative helicity near 550 m2/s2. This environment will
   continue to support a wind damage and isolated tornado threat with
   the rotating elements within the line. These stronger cells could
   also be associated with hail.
