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.
