VALID 251939Z - 252115Z

SEVERE TSTM POTENTIAL APPEARS TO BE INCREASING ACROSS THE AREA AND A
WW MAY BE REQUIRED.

BREAKS IN CIRRUS CANOPY HAVE ALLOWED FOR LOCALLY STRONG DIABATIC
HEATING THIS AFTERNOON FROM N OF UNO EWD INTO FAR SRN IL AND WRN KY.
WHEN COUPLED WITH DEWPOINTS IN THE LOWER 70S...AIRMASS HAS BECOME
VERY UNSTABLE WITH MLCAPES APPROACHING 3000 J/KG AND LITTLE OR NO
CONVECTIVE INHIBITION. LOCALIZED ASCENT ALONG COLD POOLS EMANATING
FROM TSTMS IN PROGRESS TO THE N ACROSS WW 286 SWWD INTO SWRN MO
SHOULD SUPPORT SWD TSTM DEVELOPMENT INTO DISCUSSION AREA OVER THE
