   MESOSCALE DISCUSSION 0458
   NWS STORM PREDICTION CENTER NORMAN OK
   0242 PM CDT TUE APR 26 2016

   AREAS AFFECTED...SE MO...SRN IL...FAR SW IND...NW TN

   CONCERNING...SEVERE THUNDERSTORM WATCH 106...

   VALID 261942Z - 262145Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 106
   CONTINUES.

   SUMMARY...A LINE OF SEVERE STORMS ASSOCIATED WITH DAMAGING WIND
   GUSTS AND HAIL...WILL MOVE ESEWD ACROSS SE MO...SRN IL..SW IND AND
   WRN KY THIS AFTERNOON. A NEW WW MAY BE NEEDED TO THE SOUTHEAST OF WW
   106.

   DISCUSSION...LATEST RADAR TRENDS SHOW A WELL-DEVELOPED BOWING LINE
   SEGMENT ACROSS FAR WRN IL EXTENDING SWWD INTO SE MO. THE LINE IS
   LOCATED TO THE SOUTH OF A QUASI-STATIONARY FRONT IN A MOIST AIRMASS.
   AHEAD OF THE BOW...SFC DEWPOINTS IN THE MID TO UPPER 60S F COMBINED
   WITH SFC TEMPS IN THE LOWER 80S F ARE CONTRIBUTING TO MODERATE
   INSTABILITY WITH MLCAPE OF 2000-2500 J/KG ACCORDING TO MESOSCALE
   ANALYSIS. THIS SHOULD HELP THE LINE TO BE MAINTAINED THROUGH THE
   REST OF THE AFTERNOON AND POSSIBLY INTO THE EARLY EVENING. THE
   LATEST HRRR RUN MOVES THE BOWING LINE SEGMENT ESEWD ACROSS SRN IL
   INTO SW IND AND WRN KY BY 23Z TO 00Z. THE ST LOUIS AIRPORT RECENTLY
   REPORTED A WIND GUST OF 53 KNOTS ASSOCIATED WITH THE LINE AND THIS
   POTENTIAL FOR DAMAGING WIND GUSTS SHOULD CONTINUE IN AREAS TO THE
   EAST OF THE MS RIVER ACROSS SRN IL AND WRN KY.
