Areas affected...southern Illinois...southern Indiana

Concerning...Severe potential...Watch unlikely=20

Valid 162328Z - 170030Z

Probability of Watch Issuance...20 percent

SUMMARY...Marginal risk for severe wind will continue through the
evening.

DISCUSSION...A line of storms continues eastward across southern
Illinois and southern Indiana, with occasional stronger segments
producing occasional gusts 40-50 mph. This is ongoing within a very
unstable air mass, with MLCAPE around 2500-3500 J/kg. However, deep
layer shear for organization remains weak. Occasional severe outflow
winds will be possible. However, the threat is likely to remain too
localized for watch issuance.
