THO HEAT STILL A CONCERN TDA...FCST PROBLEM HAS SHIFTED TO PCP PSBLTY
AND POTENTIAL FOR FLASH FLOODING.

VERY STG CAP HAS SLOWLY WEAKENED PAST 12 HOURS WITH MDL GRIDDS
CONTINUING TO SHOW WEAKENING TREND THROUGH NGT. ETA BUILDS CAP BACK
INTO AREA MON AFTN...BUT LOOKS A LTL TOO STRONG...PROBABLY DUE TO
TOO MUCH WARMING IN HI PLAINS. REGARDLESS...FRONT IN COMBINATION
WITH VERY HI DWPTS EXTREME...WK SHRTWV AND DIFFLUENT UPR FLO ENOUGH
TO SUPPORT DEVELOPMENT OF TRW IN VICINITY OF FRONT VERY  THIS AFTN
ACR XTRM NW MO. AGREE WITH SPC THAT DEVELOPMENT OF MCS IS LIKELY
WITH INITIAL DEVELOPMENT CRITICAL AS MBE VECTOR DENOTES S/SE
DEVELOPMENT. XPCT MCS TO DEVELOP ACR NWRN MO...AND WITH VERY HI
PRECIP WATER VALUES AND LO FFG...PLAN TO ISSUE FFA FOR NRN 2/3RDS OF
CWA FOR TNGT.

PRECIP TO END DURING EARLY AM HOURS WITH THE POTENTIAL FOR RECOVERY
OF THE AIR MASS DEPENDING UPON OUTFLO BOUNDARIES. MDLS SIMILIAR IN
POSITION OF STNRY FRONT ALONG IA/MO BDR AT 00Z TUES. POSITION
APPEARS REASONABLE BUT TNGTS CONVECTION WL HAVE MAJOR INFLUENCE ON
POSITION OF REDEVELOPMENT LATE MON AFTN. WL GO WITH MDL POSITION AT
THIS TIME AS LATE JUN INSOLATION WL LIKELY ALLOW FOR RAPID RECOVERY
OF AIR MASS. XPCT DEVELOPMENT ONCE AGAIN IN VICINITY OF FRONT DURING
LATE AFTN OR EVE HOURS AS CAP WL PRECLUDE DEVELOMENT UNTIL THAT TIME.

SHRTWV ROTATING SE ACR NRN/CNTRL PLAINS MON NGT SHOULD PUSH FRONT
INTO SRN CWA BY 12Z TUES. COOLING AND DRYING BEHIND FRONT WL BE
SLOW...BUT NRN ZONES WL LIKELY GET BREAK FROM EXCESSIVE HEAT AND
HUMIDITY.

DO NOT PLAN ON CARRYING HEAT ADV ACR NRN 2/3RDS OF CWA TNGT AND SUN
DUE TO COOLING TNGT ASSCD WITH CONVECTION AND POTENTIAL FOR HEAT
