   SRN PORTION OF THE SQUALL LINE HAS EVOLVED INTO DISCRETE SUPERCELLS
   THIS MORNING.  THE 2-6KM MEAN WIND HAS LARGELY REMAINED NORMAL TO
   THE LINE THROUGH THE LAST SEVERAL HOURS...SUGGESTING A MIXED-MODE OF
   LINE SEGMENTS AND INDIVIDUAL CELLS.  VWP/S SUGGEST VERY STRONG
   LOW-LEVEL WIND FIELDS OWING TO A STRONG AGEOSTROPHIC RESPONSE TO
   PRESSURE FALLS ACROSS THE LWR GRTLKS REGION.  0-1KM SRH IN EXCESS OF
   340 M2/S2 HAVE BEEN OBSERVED AT LOUISVILLE.  GIVEN NEARLY 70 KTS OF

   SUSTAINED DISCRETE SUPERCELLS...THERE WILL BE THE THREAT FOR AN
   ISOLD TORNADO OR TWO ACROSS SRN IND AND WRN KY.  OTHERWISE...A
   CONTINUED DAMAGING WIND THREAT WILL EXIST...ALONG WITH HAIL.
   
   PORTIONS OF SEVERE THUNDERSTORM WATCH 844 MAY REQUIRE AN UPGRADE TO
   A TORNADO WATCH SHORTLY.
