...UPDATE TO AVIATION AND MESOSCALE CONVECTIVE DISCUSSION...

.UPDATE...

CONVECTION CONTINUING TO PERCOLATE THIS EVENING ALONG WHAT APPEARS
TO BE THE COLD FRONT...MODIFIED BY NUMEROUS OUTFLOW BOUNDARIES...DROPPING
SOUTH OVER CENTRAL/SOUTHERN MISSOURI. ADDITIONAL STORMS HAVE
FORMED AS PARCELS ARE LIFTED OVER THE OUTFLOW/FRONTAL
BOUNDARY...AND EXPECT THIS TREND TO CONTINUE FOR ABOUT THE NEXT
HOUR OR SO...LIKELY TO AROUND THE I-44 CORRIDOR.
EVENTUALLY...EXPECT TO SEE BOUNDARY LATER COOLING AND SUBSEQUENT
SURFACE BASED PARCEL STABILIZATION TO TAKE HOLD...WITH CONVECTION
DIMINISHING AFTER SUNSET. UNTIL THAT TIME THOUGH...ISOLATED SEVERE
STORMS WILL BE POSSIBLE...WITH HAIL TO THE SIZE OF QUARTERS AND
WINDS TO 50-60 MPH.

.PREV DISCUSSION...
/ISSUED 130 PM CDT SUN JUL 3 2011/

A WEAK FRONT STALLED OVER CNTRL MO/EAST CNTRL KS...AND HAS BECOME REINFORCED
BY RAIN COOLED AIR TO SOME EXTENT. THIS HAS KEPT MOST OF THE FCST
AREA IN THE HOT/MUGGY AIR. TEMPERATURES ARE AGAIN APPROACHING 100
DEG F AT KJLN AND ARE IN THE LOW/MID 90S ELSEWHERE. LIKE YESTERDAY
LOWER DEW POINTS ARE KEEPING HEAT INDEX VALUES FROM GETTING WAY
OUT OF HAND...GENERALLY IN THE MID/UPPER 90S AT AIRPORT SITES AT 1
PM. CLOUD COVER AND CUMULUS DEVELOPMENT IS NOW HELPING TO SLOW THE
UPWARD DIURNAL TEMPERATURE TREND...BUT MOST AREAS SHOULD SEE 100
TO 105 DEG F HEAT INDEX VALUES BY LATE THIS AFTERNOON.

A SHORTWAVE OVER EASTERN NEB/EASTERN KS WITH CONVECTIVE CLUSTER
AHEAD OF IT OVER NORTHERN/CENTRAL MO WILL SHIFT E-SE THIS
AFTERNOON/TONIGHT. LOW LEVEL BOUNDARIES SOUTH OF THE CONVECTION INTO
WESTERN MO MAY SERVED AS A TRIGGER FOR CONVECTION THIS AFTERNOON.
STRONG/SEVERE CONVECTION HAS SKIRTED THE FAR NORTHERN CWFA WITH
THIS FEATURE...BUT WITH CONVECTIVE TEMPERATURE BEING REACHED...MAY
SEE DEVELOPMENT ALONG THIS BOUNDARY SHORTLY. ELSEWHERE...ISOLD
PULSE STORMS ARE AGAIN UNDERWAY OVER THE MO OZARKS. GIVEN THE
STRONG INSTABILITY WITH RUC PROGGED SOUNDINGS INDICATING 3000 J/KG
MLCAPES AND WITH SOME MID LEVEL DRY AIR (20-25 DEG K THETA-E
DIFFERENTIAL SFC-700/500MB)...HAIL/WIND WILL BE THE MAIN STORM
THREATS THROUGH THIS EVENING.

THE SHORTWAVE IS PROGGED TO MOVE SLOWLY SOUTHEAST TO THE BOOTHEAL
REGION BY 05/0000Z...SO OVERNIGHT CONVECTION NEAR OR JUST NORTH-
EAST OF THE CWFA WILL BE POSSIBLE THROUGH TONIGHT WHERE LOW LEVEL
CONVERGENCE IS MAXIMIZED. HAVE HIGHEST POPS OVER CNTRL MO TO COVER
THIS. ONCE THE SHORTWAVE MOVES E-SE OF THE REGION...WE MAY GET A
BREAK IN THE CONVECTION TUE-TUE EVENING. BUT WITH MORE ABUNDANT
SUNSHINE...PROGGED HEAT INDEX VALUES REACH THE 100-105 DEG F TUE
AFTERNOON.

WITH THE MAIN UPPER RIDGE AXIS OVER THE WESTERN CONUS...ANOTHER
SHORTWAVE AND ASSOCIATED SFC FRONT WILL MOVE THROUGH THE REGION
WED-WED NIGHT WITH ADDITIONAL CHANCES FOR TSTMS. AFTER THAT...SOME
NIGHTTIME CONVECTION MAY AFFECT AREAS NORTH OF THE
FRONT...GENERALLY FAVORING THE SW AND SOUTHERN CWFA DEPENDING ON
WHERE THE BAROCLINIC ZONE SETS UP. IN LATER PERIODS...BOTH THE GFS
AND ECMWF INDICATE THE UPPER RIDGE BUILDING BACK TO THE NORTHEAST
INTO THE AREA BY NEXT WEEKEND.

.AVIATION...

FOR THE 00Z TAFS...

UNCERTAIN SHORT TERM FORECAST FOR THE TERMINALS...AS TSRA OVER
SOUTH CENTRAL MISSOURI CONTINUES TO BUILD SOUTH ALONG SEVERAL
OUTFLOW BOUNDARIES. HAVE DOUBTS AS TO HOW FAR SOUTH CONVECTION
WILL DEVELOP BEFORE EVENING STABILIZATION TAKES HOLD. AS
SUCH...HAVE ONLY INDICATED CB GROUPS IN THE TAFS FOR THIS EVENING
ATTM...BUT MAY NEED TO AMEND IF TSRA GETS CLOSE TO THE TERMINALS.
VFR CONDITIONS CAN BE EXPECTED OUTSIDE OF TSRA...WITH MVFR AND
PERHAPS OCCASIONAL IFR WITHIN TSRA.

WINDS WILL REMAIN LIGHT TONIGHT AND TOMORROW...GENERALLY FROM THE
EAST TO NORTHEAST ONCE THE MODIFIED COLD FRONT PASSES. ON
MONDAY...EXPECT TO SEE ADDITIONAL CONVECTION FORM BY
AFTERNOON...AND HAVE INCLUDED CB GROUPS AFTER 18Z TOMORROW.
