Mesoscale Discussion 0794

Areas affected...northern into eastern Missouri and southwest
Illinois

Concerning...Severe potential...Watch possible=20

Valid 141743Z - 142015Z

Probability of Watch Issuance...40 percent

SUMMARY...Storms are expected to develop over northern Missouri, and
may pose a damaging wind and marginal hail threat as they progress
east/southeastward toward the Mississippi River and into western
Illinois.

DISCUSSION...Visible imagery shows towering cumulus and deepening
convection now over northern MO, near a weak boundary. This boundary
becomes less defines farther east into IL, but a minor differential
heating zone does exist.

While winds aloft are not very strong, heating and ample moisture
will continue to destabilize the region. Conditions appear favorable
for a cluster of storms to form near the stronger part of the front
over northern MO, and hodographs will favor and east/southeastward
storm motion. Given the favorable time of day with steepening
low-level lapse rates and precipitable water near 1.50", at least
isolated severe gust potential appears likely, with marginal hail in
some of the stronger cores as well.
