.DISCUSSION...
/330 PM CDT MON MAY 26 2008/

MAIN CONCERN DEALS WITH ADDITIONAL HEAVY RAINFALL AND SEVERE
WEATHER POTENTIAL TONIGHT INTO TOMORROW. DO NOT PLAN ANY CHANGES
TO GOING FLASH FLOOD WATCH AT THIS TIME.

HAVE HAD A BREAK FROM TSRA SINCE MID MORNING AS ATMOSPHERE HAS
BEEN RELATIVELY STABLE GIVEN THE OUTFLOW BOUNDARY HAS MOVED WELL
SOUTH AND SOUTHWEST OF THE CWA AND QUASI-STATIONARY MCS OVER SERN
KANSAS CONTINUES TO SPREAD DEBRIS CLOUDINESS ACROSS THE REGION.
STILL...LATEST SATELLITE IMAGERY INDICATES CIRRUS HAS THINNED OVER
PARTS OF THE NRN AND WRN CWA WITH SOME INCREASE IN THE CU FIELD
OVER NERN MO. OBJECTIVE ANALYSIS REVEALS MUCAPES ARE NOW IN THE
500-1500 J/KG RANGE...SO CERTAINLY EXPECT CHANCES OF TSRA TO
INCREASE INTO THE EVENING. LATEST SWODY1 HAS REMOVED THE SLIGHT
RISK FROM MOST OF THE AREA GIVEN THE DECREASED STABILITY AND THE
RELATIVELY WEAK SHEAR (0-6KM SHEAR 25-35KTS)...THOUGH MAY STILL
MAY SEE SOME STRONG TO LOCALLY SEVERE STORMS. RUC/NAM STILL LOOK
TO BEING INCREASING THE AMOUNT OF 925-850MB MOISTURE CONVERGENCE/
TRANSPORT OVER THE AREA THROUGH THE EVENING AND OVERNIGHT. SURFACE
FRONT CURRENTLY EXTENDING OVER SRN IA INTO SRN WI WILL ALSO MOVE
SWD INTO THE NRN CWA LATE TONIGHT. THESE FEATURES SHOULD CAUSE AREAL
COVERAGE OF SHRA/TSRA TO INCREASE WITH TIME. FORECAST PW VALUES
AS HIGH AS 1.8 INCHES INDICATE THAT ANY STORMS MAY PRODUCE
ADDITIONAL HEAVY RAINFALL WHICH COULD CAUSE ADDITIONAL FLASH
FLOODING GIVEN THE RAINFALL RECEIVED OVER MOST OF THE CWA THE PAST
24-36 HOURS.

WUSED THE NAM THROUGH TOMORROW AS THE GFS SHOWS TOO MUCH
CONVECTIVE FEEDBACK INITIALLY...THEN LEANED MORE TOWARD THE GFS
BY WEDNESDAY AS THE NAM LOOKS TOO STRONG WITH SHORTWAVE TROUGH
MOVING OVER THE CNTRL CONUS RIDGE ON WEDNESDAY COMPARED TO THE
OTHER MODELS. FRONT SHOULD MOVE THROUGH THE CWA BY LATE TOMORROW.
KEPT LIKELY POPS GOING THROUGH TOMORROW AS FRONT PASSES THROUGH
AND THEN ADDED CHC POPS OVER THE AREA TUESDAY NIGHT GIVEN WARM AIR
ADVECTION AHEAD OF WEAK SHORTWAVE TROUGH ON WEDNESDAY. SHOULD THEN
SEE A SHORT DRY PERIOD BEFORE ANOTHER SYSTEM BRINGS A CHANCE OF
SHRA/TSRA TO THE AREA ON FRIDAY INTO SATURDAY AS NEXT SHORTWAVE
DRAGS A FRONT THROUGH THE AREA.

FOLLOWED CLOSER TO THE GFS MOS FOR TEMEPRATURES. HIGHS ON
WEDNESDAY WILL BE WELL BELOW NORMAL AFTER BEING SUMMERLIKE YESTERDAY.
