AREAS AFFECTED...E-CNTRL IND INT0 CNTRL OH

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 181753Z - 181900Z

THE POTENTIAL FOR A FEW SEVERE STORMS CAPABLE OF ISOLATED DAMAGING
WINDS AND LARGE HAIL WILL EXIST WITH INTENSIFYING TSTMS THIS
AFTERNOON AND EVENING. A WW IS NOT CURRENTLY ANTICIPATED...THOUGH
CONVECTIVE TRENDS ARE BEING MONITORED.

TRENDS IN REGIONAL RADAR IMAGERY SHOW TSTMS SLOWLY INTENSIFYING OVER
PARTS OF E-CNTRL IND/W-CNTRL OH INVOF WAVY FRONTAL BOUNDARY
STRETCHING FROM W-CNTRL IL EWD THROUGH CNTRL OH.  HERE...DAYTIME
HEATING COUPLED WITH DEWPOINTS IN THE UPPER 60S TO LOWER 70S ARE
CONTRIBUTING TO A MODERATELY UNSTABLE AIR MASS WITH MLCAPES OF
1000-1500 J/KG.  PRIMARY FACTORS LIMITING A MORE ORGANIZED SEVERE
THREAT APPEAR TO BE LOCAL MINIMUMS IN MID TROPOSPHERIC LAPSE RATES
AND WINDS.  STILL...SOME THREAT OF ISOLATED SEVERE WEATHER WILL
EXIST OWING TO THE MOIST BOUNDARY-LAYER CONDITIONS AND RESULTANT
MODERATE INSTABILITY.
