   THUNDERSTORMS ARE EXPECTED TO CONTINUE DEVELOPING EWD TOWARD CNTRL
   IND...REACHING WRN OH THIS EVENING. STORMS WILL BEGIN APPROACHING
   THE ERN EDGE OF WW 49 AFTER 19Z...AND A NEW WW WILL LIKELY BE NEEDED
   SOON.
   
   BROKEN OF LINE OF STORMS CONTAINING SUPERCELLS AND LINE SEGMENTS
   CONTINUES EAST AT 45 TO 50 KT. STORMS ARE CURRENTLY MOVING THROUGH
   AN AXIS OF MARGINAL INSTABILITY WITH MLCAPE AROUND 500-800 J/KG.
   INSTABILITY WILL REMAIN MORE LIMITED FARTHER EAST ACROSS IND DUE IN
   PART TO WIDESPREAD CLOUD WHICH WILL LIMIT FURTHER WARMING OF THE
   BOUNDARY LAYER. NEVERTHELESS...FORCING FOR ASCENT ASSOCIATED WITH
   EJECTING COMPACT SHORTWAVE TROUGH AND ITS ATTENDANT LOW LEVEL JET
   WILL LIKELY MAINTAIN DEEP CONVECTION NEXT SEVERAL HOURS. THE STRONG
   BULK SHEAR AND SIZE OF LOW LEVEL HODOGRAPHS WILL CONTINUE TO SUPPORT
   SUPERCELLS AND BOWING SEGMENTS WITH A THREAT OF DAMAGING WIND AND
   ISOLATED TORNADOES.
