205 PM CDT WED AUG 15 2001

PRECIPITATION CHANCES TONIGHT AND FRIDAY NIGHT/SATURDAY ARE THE MAIN
CONCERN FOR THIS FORECAST PACKAGE.

STILL WAITING FOR CONVECTION TO FIRE ACROSS KANSAS ALONG AND AHEAD
OF COLD FRONT. SCATTERED WARM AIR ADVECTION SHOWERS CONTINUED IN
CENTRAL MISSOURI. TEMPERATURES HAVE WARMED NICELY ACROSS THE
FORECAST AREA...WITH MIDDLE 80S TO NEAR 90 IN THE WESTERN HALF.
SURFACE DEWPOINTS HAVE ALSO RISEN INTO THE MIDDLE 60S. LATEST
SURFACE DATA PLACED COLD FRONT JUST WEST OF WICHITA.

MODELS IN GOOD AGREEMENT IN THE FIRST 36 HOURS...MOVING COLD FRONT
AND ASSOCIATED PRECIPITATION THROUGH THE FORECAST AREA BY MID
MORNING THURSDAY.

IN THE NEAR TERM...HAVE KEPT A GOOD CHANCE/LIKELY POP IN ALL ZONES
TONIGHT. SHOWERS AND THUNDERSTORMS SHOULD DEVELOP BETWEEN WICHITA
AND CHANUTE LATER THIS AFTERNOON...AND SPREAD EAST OVERNIGHT.
COVERAGE MAY BE BETTER IN EASTERN SECTIONS ONCE THE LINE BECOMES
ORGANIZED AND MATURE.

NEXT QUESTION IS FRIDAY NIGHT INTO SATURDAY. ETA/MESOETA AND AVN TRY
TO DEVELOP A COMPLEX OF STORMS IN SOUTHEAST KANSAS FRIDAY
NIGHT...AND MOVE IT ACROSS SOUTHERN MISSOURI SATURDAY. INHERITED
CHANCE POPS FOR SATURDAY...AND HAVE ADDED A CHANCE POP FOR WESTERN
SECTIONS FRIDAY NIGHT.

THANKS TO WFO ICT FOR COORDINATION THIS AFTERNOON
