.DISCUSSION...
/420 AM CDT TUE JUN 15 2010/

AN UPPER LEVEL LOW WAS LOCATED OVER SD WITH A SHORTWAVE TROF OVER
WRN KS PER EARLY MORNING WATER VAPOR IMAGERY. SFC ANALYSIS SHOWED A
QUASISTATIONARY FNT STRETCHED SWWD FM IA THROUGH SERN NEB INTO KS
AND THE OK/TX PANHANDLES. CONVECTION HAS FIRED ALONG THE BDRY IN KS
EARLY THIS MORNING WITHIN AN AREA OF H92-H85 MCONV LOCATED BENEATH
THE RIGHT ENTRANCE REGION OF H3 JET WITH ADDITIONAL LIFT PROVIDED BY
THE AFOREMENTIONED SHORTWAVE TROF. MCS OVER OK HAS MADE STEADY EWD
PROGRESS AND COULD CLIP THE FAR SRN PORTION OF THE CWA THIS MORNING.

SFC BDRY SHOULD FINALLY SINK SWD TODAY AS THE UPPER LOW CONTINUES
MOVING NEWD INTO THE WRN GRTLKS. PLENTY OF SUNSHINE TODAY WILL
CREATE ENOUGH INSTABILITY TO SUPPORT TSRA DVLPMT INVOF THE
BDRY...ESPECIALLY IN THE SERN CWA THIS AFTN/EARLY TONIGHT AS LARGE
SCALE ASCENT INCREASES AHEAD OF A SHORTWAVE TROF. ANY STORMS THAT
FORM COULD PRODUCE VERY HEAVY RAINFALL GIVEN PW VALUES OF 1.6 TO 1.8
INCHES AND DEPTH OF THE WARM CLOUD LAYER.

A BRIEF PD OF DRY WEATHER IS EXPECTED LATE TONIGHT AND WED AS
RIDGING BUILDS IN ACROSS THE CENTRAL CONUS. THU AND FRI LOOK QUITE
WARM AS SLY TO SWLY FLOW SETS IN AROUND THE SFC HIGH AND H85 TEMPS
CLIMB TO +18 TO +22 DEG C. HAVE GENERALLY TRENDED WARMER THAN
GUIDANCE FOR THU/FRI BUT THIS MAY NOT BE WARM ENOUGH. THE NEXT
SYSTEM LIFTS THROUGH THE NRN PLAINS ON FRI AND COULD BRING SCT TSRA
TO THE NRN PARTS OF THE CWA. NO CHANGES PAST 00Z SAT.

.AVIATION...
/1243 PM CDT TUE JUN 15 2010/

ANTICIPATION FOR THIS AFTN IS FOR KUIN-KCOU TO REMAIN REMOVED FROM
TSRA CHCS. EXPECT SHRA TO CONTINUE OVER THE NEXT COUPLE OF HRS AS
AN UPR LVL DISTURBANCE ALONG A SFC FRONTAL BNDRY SLIDES EWD.
FURTHER SOUTH WHERE INSTABILITY AND MOISTURE ARE MORE PREVALENT
TSRA CHCS ARE GREATER. EXPECT WITHIN THE FIRST FEW HRS OF TAF FCST
FOR KSTL-KSUS BEST CHCS FOR CONVECTIVE GUSTS AND MVFR CONDITIONS
WITH ISOLD-SCT TSRA. WOULD NOT BE SURPRISED TO SEE PSBL IFR. AS
TSRA EJECTS NEWD WITH UPR LVL DISTURBANCE...SWLY WINDS TO RETURN
AND SKIES SHOULD CLEAR INTO OVRNGT PD.

SPECIFICS FOR KSTL...TSRA ALREADY APPROACHING TERMINAL FROM THE
SOUTH AND SHOULD IMPACT SHORTLY AFTER 18Z. MAIN THREATS INCLUDE
POTENTIAL CONVECTIVE GUSTS WITH MVFR-IFR VSBYS AND CIGS. WILL
CLOSELY MONITOR THE SITUATION AND AMEND AS NECESSARY FOR
ADDITIONAL CONVECTIVE THREATS. CONFIDENCE LIES THAT CONVECTIVE
POTENTIAL WILL LAST FOR ONLY THE NEXT FEW HRS AND PROGRESS NEWD
INTO LATER AFTN AND EVNG.
