   CONCERNING...SEVERE THUNDERSTORM WATCH 608...
   
   VALID 080058Z - 080230Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 608
   CONTINUES.
   
   00Z SOUNDINGS FROM SGF AND LZK BOTH SHOW SUBSTANTIAL MOISTURE AND
   INSTABILITY WITH LITTLE CONVECTIVE INHIBITION. DESPITE THIS...STORMS
   OVER NRN AR HAVE WEAKENED QUICKLY...AND THIS WAS MOST LIKELY DUE TO
   A COMBINATION OF SUB PAR MASS CONVERGENCE AND WEAK SHEAR PROFILES.
   FURTHER...VISIBLE IMAGERY INDICATES A STABILIZING BOUNDARY LAYER
   ACROSS W MO...AND NWRN PORTIONS OF THE WATCH BEHIND THE WIND SHIFT
   MAY BE ABLE TO BE CLEARED SOON.
   
   FARTHER N INTO MO...WIND FIELDS ARE STRONGER IN ASSOCIATION WITH THE
   UPPER SHORTWAVE TROUGH AND ONGOING CONVECTIVE COMPLEX. INTENSE
   STORMS WITH WIND AND HAIL THREAT SHOULD PERSIST OVER MUCH OF THE ERN
   WATCH AREA...AND POSSIBLY PERSISTING INTO SRN IL...SWRN IND...WRN KY
   THIS EVENING. ADDITIONAL WATCHES ARE UNLIKELY...BUT A FEW COUNTIES
   MAY BE ADDED TO THE ERN EDGE OF THE EXISTING WATCH IF STORMS
   MAINTAIN INTENSITY.
