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.
