MESOSCALE DISCUSSION 1924
NWS STORM PREDICTION CENTER NORMAN OK
1112 AM CDT TUE AUG 11 2026
AREAS AFFECTED...SOUTHEAST INDIANA INTO WEST-CENTRAL AND SOUTHWEST
OHIO
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 111612Z - 111715Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...THE THREAT FOR SEVERE WEATHER IS EXPECTED TO INCREASE BY
EARLY AFTERNOON, LIKELY REQUIRING A NEW SEVERE THUNDERSTORM WATCH.
DISCUSSION...RECENT TRENDS IN BASE VELOCITY DATA INDICATE A
STRENGTHENING COLD POOL WITH THE LEADING EDGE OF THUNDERSTORMS NEAR
MARION, IN. THAT CONVECTION IS LOCATED TO THE NORTH OF AN OUTFLOW
BOUNDARY STRETCHING FROM NORTHWEST THROUGH SOUTHEAST IN. HOWEVER,
PREVAILING WEST-SOUTHWEST LOW-LEVEL WINDS (PER KIND VWP) WILL LIKELY
SUPPORT THE EASTWARD MOVEMENT OF THE BOUNDARY WITH RESULTANT AIR
MASS RECOVERY EXPECTED ACROSS PORTIONS OF WESTERN OH BY EARLY
AFTERNOON. AS SUCH, IT APPEARS LIKELY THAT THE ABOVE-MENTIONED
STORMS WILL CONTINUE TO SPREAD SOUTHEAST INTO THE DISCUSSION AREA
WITHIN THE NEXT HOUR OR SO. DAMAGING WIND GUSTS WILL BE THE PRIMARY
HAZARD WITH THE MOST INTENSE STORMS.
