NATIONAL WEATHER SERVICE WICHITA KS
716 PM CDT SAT MAY 21 2011

.AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
MAIN AVIATION FORECAST CONCERN IS A CHANCE FOR THUNDERSTORMS THIS
EVENING AND MVFR CONDITIONS BY MORNING IN SOUTH CENTRAL AND
SOUTHEASTERN KANSAS.

CURRENT TRENDS IN CONVECTION LOOK TO MISS ALL TERMINALS...BUT KCNU
COULD STILL BE IMPACTED. ALTHOUGH DUE TO LOW CONFIDENCE HAVE
REMOVED CB AND VCTS. EXPECT WINDS TO DIMINISH AS SUN SETS AND
WINDS WILL GENERALLY BE LIGHT.

AT KICT AND KCNU SOME ELEVATED MOISTURE AND BOUNDARY LAYER COOLING
WILL HELP DEVELOP MVFR CEILINGS BY MORNING. CONFIDENCE IS HIGHEST AT KCNU
WHERE MOISTURE IS WELL IN PLACE. A WIND SHIFT WILL MOVE ACROSS
THE AREA AS WINDS BECOME WEST-NORTHWESTERLY DURING THE AFTERNOON
SUNDAY. ANOTHER CHANCE FOR THUNDERSTORMS EXISTS FOR KCNU LATE
SUNDAY AFTERNOON...BUT WITH CONFIDENCE OF COVERAGE AND LOCATION
BEING LOW...JUST INCLUDED CB AFTER 2200Z.

OVER NEARLY ALL OF CNTRL & ERN KS EARLY THIS AFTERNOON...AN INCREASE OF
500-1,000 J/KG FROM 10AM-1PM. WITH N-S ORIENTED DRYLINE MEANDERING FROM

MOISTURE WILL BEGIN TO POOL ALONG THE STALLED FRONT LATE SUNDAY NGT THUS
SETTING STAGE FOR WET START TO THE WORK-WEEK.

MON-WED:
A WEAK NE-MOVG MID-LVL TROF IS SCHEDULED TO ARRIVE KS ON MON WHICH WOULD
INDUCE SUBTLE WARM-FRONTOGENESIS ACROSS SRN KS. WITH THE WARM FRONT MOVG
SLOWLY N THE HIGH OCTANE FUEL POOLING ALONG THE BOUNDARY WILL LIKEWISE
LIFT N. AS SUCH +TSRA WILL INCREASE MARKEDLY FROM MON THRU TUE NGT WITH
FLOODING BECOMING A MAJOR CONCERN DURING THESE PERIODS AS A MID-UPR LOW
STRENGTHENS AS IT MOVES SE ACROSS KS TO ENHANCE LIFT. BY WED EVENING THE
MID-UPR LOW SHOULD MOVE ALONG THE MO/AR BORDER...THEREBY BRINGING AN END
TO TS BUT -RA SHOULD PERSIST THRU WED NGT.

THU-FRI NGT:
PREDOMINANTLY DRY & GRADUALLY WARMER WEATHER IS FORECAST FOR THESE LATER
PERIODS AS A RIDGE AXIS...ALBEIT DEAMPLIFYING...MOVES SE OVER THE CNTRL

EARLY THIS EVENING...MAINLY ACROSS CENTRAL AND SOUTHEAST KANSAS.
OCCASIONAL MVFR CIGS WITHIN AND OUTSIDE OF ANY CONVECTION IS
EXPECTED IN THESE AREAS AND FOR NOW WILL ONLY MENTION VCTS UNTIL
TIMING OF ANY IMPACT IS MORE CERTAIN. OTHERWISE RATHER LIGHT AND
