SPC MESOSCALE DISCUSSION 1700 FOR...NRN/ERN KY AND OH...
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
   
   VALID 141732Z - 142100Z
   
   PARTS OF THE OH VALLEY AND CNTRL/NRN OH ARE BEING MONITORED FOR
   CONVECTIVE TRENDS. A SEVERE TSTM WATCH MAY BE NEEDED OVER THE
   REGION LATER THIS AFTERNOON. 
   
   NUMEROUS MULTI-CELL CLUSTERS OF TSTMS WERE BEGINNING TO INCREASE IN
   INTENSITY ACROSS SWRN AND SRN OH ATTM. ANOTHER PERSISTENT AREA OF
   TSTMS WAS MOVING NEWD ACROSS NRN KY POSSIBLY SUSTAINED BY WEAK
   MIDLEVEL SHORT WAVE TROUGH EMBEDDED WITHIN DEEP SWLY FLOW. THIS
   ACTIVITY WILL REMAIN SOMEWHAT REMOVED FROM STRONGER DEEP LAYER
   SHEAR ASSOCIATED WITH SYNOPTIC FRONTAL ZONE OVER MI/IND AREA AND
   THIS MAY LIMIT STORM ORGANIZATION. HOWEVER...SLOWLY STRENGTHENING
   MIDLEVEL FLOW...AND LARGE SCALE ASCENT WITHIN RIGHT ENTRANCE REGION
   OF UPPER JET MAX WILL SUPPORT INCREASING TSTM COVERAGE OVER THE
   NEXT SEVERAL HOURS. IN ADDITION...DEGREE OF DESTABILIZATION...
   MLCAPE EXCEEDING 1000 J/KG WILL SUPPORT STRONG UPDRAFTS WITH SOME
   POTENTIAL FOR DAMAGING WINDS AND PERHAPS SOME ISOLD HAIL. THIS
   POTENTIAL WILL CONTINUE TO BE MONITORED AND A WATCH MAY BE ISSUED
   WITHIN AN HOUR OR TWO.
