   AREAS AFFECTED...OH...FAR NRN KY

   CONCERNING...TORNADO WATCH 566...

   VALID 172306Z - 180000Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 566 CONTINUES.

   SUMMARY...DMGG WIND AND TORNADO RISK WILL PERSIST ACROSS OH AND FAR
   NRN KY. WITH TIME...DMGG WIND GUSTS /SOME SIGNIFICANT/ SHOULD BECOME
   THE DOMINANT THREAT.

   DISCUSSION...QLCS CONTINUES TO PROGRESS ACROSS SERN IND INTO NWRN
   OH...WITH SYNOPTIC COLD FRONT OVERTAKING SRN PORTIONS OF THIS LINE.
   EMBEDDED CIRCULATIONS CONTINUE TO BE NOTED...AND SIGNIFICANT 
   LOW-LEVEL SHEAR PRESENT /E.G. 45 KT IN 0-1 KM LAYER PER ILN VWP
   DATA/ WILL SUPPORT SVR WIND GUST AND ISOLATED TORNADIC POTENTIAL.
   PRE-FRONTAL SHOWERS/TSTMS INTO CNTRL OH HAVE LARGELY REMAINED
   UNORGANIZED...BUT AN ACCOMPANYING TORNADO RISK MAY EXIST WITH ANY
   SUSTAINED ROTATING STORMS THAT CAN EVOLVE. 

   INTO THE LATE EVENING...THE COLD FRONT WILL CONTINUE TO OVERTAKE THE
   ENTIRE LENGTH OF THE QLCS. DESPITE THE LOSS OF DIURNAL HEATING AND A
   SLIGHTLY LESS MOIST BOUNDARY LAYER WITH EWD PROGRESSION...THE
   MAGNITUDE OF LARGE-SCALE FORCING COMBINED WITH VERY STRONG LOW-LEVEL
   FLOW/SHEAR WILL CONTINUE TO SUPPORT A DMGG WIND GUST THREAT
   /POTENTIALLY SIGNIFICANT/ ACROSS ALL OF OH...INCLUDING THE COLUMBUS
   AND CLEVELAND METRO AREAS.
