FCST PROB OF THE PD...POPS...

WELL DEFINED MCV ROAMING THRU CNTRL MO ATTM...WITH KSGF 88D SHOWING
EYE WITH FEW TSRA NR COU/JEF.  OTHERWISE OUTFLOW FROM MCS PUSHED WELL
TO OUR SOUTH INTO ARK/ERN OKLA FIRING STORMS FROM NR FSM TO JBR.
ANOTHER WELL DEFINED BOUNDARY SEEN OVR CNTRL KS FROM WK SFC LOW NR HYS
SSE TO BTWN PNC/END OKLA.  THE TWO ABOVE AREAS SHOULD STAND THE BEST
CHC OF SEEING TSRA THIS AFTN/EVE.  ATMOSPHERE OVER SW MO/SE KS HAS
STABLIZED QUITE A BIT...BUT WITH WARMING MAY SEE WIDELY SCT TSRA FORM
LATE THIS AFTN/EVE...WITH BEST CHC COU TO UNO AREA EAST CLOSER TO MCV.

CONFIDENCE THIS FCST IS LOW AS MESOSCALE FEATURES MAKE TSTM FORECASTING
VERY DIFFICULT.  WILL CONTINUE TO SIDE WITH NGM POSITIONING OF FRONT
AND ITS OTHER FEATURES THIS PD.  NGM SHOWS STRONG MOIST CONVERGENCE OVR
SCNTRL KS AT 00Z AND WATER VAPOR LOOP SHOWING MOISTURE SURGING NORTH
INTO CO/WRN KS.  THUS THINK COMPLEX OF STORMS MAY GET GOING TONIGHT OVR
WRN OR CNTRL KS/ERN CO/PSBLY SW NEBRASKA.  IF THIS HAPPENS ANY MCS WOULD
SLIDE SE AND SHOULD JUST BRUSH WRN PART OF CWA....BUT CONFIDENCE ON THIS
IS NOT HIGH.  OTHERWISE...EXPECT COLD FRONT TO OUR NORTH TO SLIDE SLOWLY
SOUTH INTO NRN MO AND THIS MAY CAUSE A FEW TSRA TONIGHT.

FOR WEDNESDAY AND THURSDAY...FRONT TO SLIDE SOUTH...WITH BIGGEST PUSH
OVR KY/TN AS HIGH PRESSURE BUILDS OVER THE GREAT LAKES.  THINK FRONT TO
STALL OUT NR A BNA-SGF-RSL LINE BY WED NIGHT...AND THEN BEGIN TO RETURN
NORTH ON THURSDAY.  WITH FRONT IN AREA WILL NEED TO CARRY POPS EACH
PERIOD BUT CONFIDENCE IS LOW SO WILL KEEP IT AT 30 PCT.

AS FOR TEMPS...WILL TEND TOWARD FWC...WITH ONLY MINOR MODIFCATIONS.

MY THOUGHTS FOR TONIGHT...(FOLLOWS WRKZFP FROM STL WELL)
ALL AREAS...PTLY CLDY...30 OR 40 POP...LOWS MID/UPR 60S.  SW 5-10.
