.DISCUSSION...
/403 AM CDT THU JUN 16 2011/

HIGH PRESSURE CENTER WAS LOCATED OVER THE CWA EARLY THIS MORNING
WITH A QUASISTATIONARY FRONT STRETCHING ACROSS CENTRAL AR INTO
CENTRAL/NRN OK. THIS FRONT WILL START TO LIFT NEWD AS A WMFNT TODAY
AS A LOW PRESSURE SYSTEM DEVELOPS OVER ERN CO/WRN KS. THERE ARE
STILL SOME QUESTIONS ABOUT HOW FAR NORTH THE WMFNT WILL REACH TODAY
BECAUSE A POTENTIAL MCS OVER ERN KS/WRN MO LATER TODAY MAY PRODUCE
ENOUGH PCPN...CLOUDINESS...AND OUTFLOW TO KEEP THE FRONT ACROSS
EXTREME NERN OK/SWRN MO. A BROKEN LINE OF THUNDERSTORMS HAS ALREADY
DEVELOPED ACROSS KS EARLY THIS MORNING IN AN AREA OF H85 MCONV SHOWN
BY THE RUC. THIS AREA OF MCONV IS FCST TO PROGRESS EWD SO THERE MAY
BE A FEW THUNDERSTORMS IN THE WRN PART OF THE CWA. THIS FCST PACKAGE
REFLECTS THE IDEA THAT THE POTENTIAL MCS WOULD FORM OUT WEST AND
MOVE SEWD THIS MORNING BASED ON FCST CORFIDI VECTORS.

MODELS SHOW THE WMFNT PUSHING NE OF THE CWA BY LATE FRI AFTN BUT
THIS MAY BE TOO RAPID...THEREFORE CONTINUED CHC POPS AND DID NOT
INCREASE TEMPERATURES. PCPN CHCS OVER THE NEXT FEW DAYS WILL BE TIED
TO THE LOCATION OF THE WMFNT AND PARTS OF THE AREA HAVE BEEN
OUTLOOKED BY SPC FOR FRI AND SAT.

ONCE THE FRONT LIFTS NEWD...HOT AND HUMID CONDITIONS RETURN TO THE
AREA FOR THE WEEKEND AND EARLY NEXT WEEK. HEAT INDEX READINGS COULD
EXCEED 100 DEGREES ON SAT AND SUN ACROSS MOST OF THE CWA. FEW
CHANGES PAST 12Z SUN.

.AVIATION...
/507 AM CDT THU JUN 16 2011/

CHALLENGING FORECAST THIS MORNING AS MUCH OF THE FORECAST FOR THIS
AFTERNOON AND TONIGHT HINGES ON WHAT DEVELOPS TO THE NORTHWEST OVER
THE NEXT FEW HOURS. LATEST MESOSCALE MODEL GUIDANCE DEPICTS THE
ELEVATED CONVECTION ACROSS EASTERN KANSAS GROWING INTO A LARGE
FORWARD PROPOGATING MCS THIS MORNING/AFTERNOON AND DROPPING
SOUTHEAST ACROSS THE SOUTHWESTERN HALF OF THE STATE OF MISSOURI.
GIVEN THIS SCENARIO... GREATEST POTENTIAL OF THUNDERSTORMS WILL BE
AT KCOU. MEANWHILE...BAND OF MOISTURE CONVERGENCE AT 850MB WILL
SLOWLY MOVE NORTHEAST PROVIDING AT LEAST A CHANCE OF SHOWERS OR
SPRINKLES. LATEST RADAR TRENDS SUPPORT THIS WITH WEAK ECHOES
STRETCHING FROM MOBERLY TO ROLLA.

WITH WARM FRONT STUNTED BY TODAYS CONVECTION...THE STAGE SHOULD BE
SET FOR ADDITIONAL THUNDERSTORM DEVELOPMENT LATE TONIGHT AND INTO
FRIDAY MORNING AS THE LOW LEVEL JET REESTABLISHES ITSELF. ASSOCIATED
MOISTURE CONVERGENCE TRANSLATING FROM NORTH CENTRAL MISSOURI AT 06Z
TO EAST CENTRAL MISSOURI BY 12Z FRIDAY. HAVE INCLUDED PROB30 GROUPS
AT TERMINALS TO ACCOUNT FOR THIS.

SPECIFICS FOR KSTL...
CURRENT RADAR TRENDS SUGGEST THAT A VCSH WILL BE WARRENTED THIS
MORNING. OTHERWISE...WILL HAVE TO WAIT AND SEE HOW CONVECTION
DEVELOPS OUT WEST AND IF IT WILL CLIP ST. LOUIS THIS AFTERNOON.

NEXT CHANCE OF THUNDERSTORMS SHOULD ARRIVE LATE TONIGHT AND INTO
FRIDAY MORNING WITH LOW LEVEL JET AND ASSOCIATED MOISTURE
CONVERGENCE.
