AREAS AFFECTED...S-CNTRL INTO SERN KS

CONCERNING...SEVERE THUNDERSTORM WATCH 497...

VALID 170349Z - 170445Z

THE THREAT FOR LOCALLY DAMAGING WINDS IS EXPECTED TO INCREASE E OF
WW 497 BY 0430Z AND AN ADDITIONAL WW MAY BE REQUIRED.

AS OF 0330Z...ICT RADAR IMAGERY SHOWED LEADING EDGE OF CONVECTIVE
LINE FROM CNTRL MARION COUNTY SSWWD INTO CNTRL SUMNER COUNTY WITH A
SYSTEM MOTION OF ROUGHLY 265/35 KTS.  STRONGEST PORTION OF THIS LINE
HAS RECENTLY MOVED THROUGH THE ICT AREA WHERE SEVERAL REPORTS OF
SEVERE WIND GUSTS AND WIND DAMAGE HAVE BEEN RECEIVED.  ICT/VNX VWP
DATA SHOW THE PRESENCE OF A 40-45 KT REAR INFLOW JET BELOW 2 KM AGL
WHICH IS LIKELY ENHANCING DAMAGING WINDS ALONG THE LEADING EDGE OF
THE SYSTEM GUST FRONT.

IT APPEARS THAT THIS GUST FRONT IS BEGINNING TO ACCELERATE AHEAD OF
THE PARENT CONVECTION...SUGGESTING THE A GRADUAL UPSHEAR TILT TO THE
LEADING UPDRAFT TOWERS.  THUS...THERE MAY BE SOME TENDENCY FOR A
DECREASE IN PEAK WIND GUSTS AS MCS SHIFTS E OF WW 497...THOUGH
LOCALLY DAMAGING WINDS WILL STILL REMAIN POSSIBLE.
