AREAS AFFECTED...SOUTHERN IL...FAR WESTERN KY...AND FAR SOUTHWESTERN
IN
CONCERNING...TORNADO WATCH 162...
VALID 272058Z - 272230Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 162 CONTINUES.
SUMMARY...MONITORING FOR SUPERCELL DEVELOPMENT AND THE POTENTIAL FOR
STRONG-INTENSE TORNADOES OVER THE NEXT COUPLE HOURS.
DISCUSSION...CONVECTION IS GRADUALLY INCREASING ACROSS FAR SOUTHERN
IL AND VICINITY, WHERE BOUNDARY-LAYER DEWPOINTS HAVE INCREASED TO
NEAR 70F -- RESULTING IN A STRONGLY UNSTABLE AIR MASS. ADDITIONALLY,
THE PAH VWP AND RECENT MESOANALYSIS DATA INDICATE A LARGE
CLOCKWISE-CURVED HODOGRAPH, WITH EFFECTIVE SRH INCREASING TO AROUND
300 M2/S2. THE STRONG BUOYANCY, ENHANCED LOW-LEVEL STREAMWISE
VORTICITY, AND EXPECTED DISCRETE STORM MODE WILL FAVOR AN INCREASING
RISK OF SUPERCELLS CAPABLE OF PRODUCING STRONG-INTENSE TORNADOES AND
VERY LARGE HAIL/DAMAGING WINDS OVER THE NEXT COUPLE HOURS.
