AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1252 PM CDT MON MAY 26 2008

.UPDATE...

.AVIATION...
FOR THE 18Z TAF SUITE.
CURRENT CONVECTION ACROSS SOUTHEAST KS CONTINUES TO DIMINISH AT THIS
TIME.  WILL KEEP SOME VCTS IN THE KCNU TAF FOR AT LEAST THE NEXT
COUPLE OF HOURS UNTIL THIS CONVECTION COMES TO AN END.  ALSO NOTED
SOME MVFR CEILINGS ACROSS CENTRAL AND SOUTH CENTRAL KS.  EXPECT THIS
CLOUD COVER TO SLOWLY BURN OFF AS THE AFTERNOON PROGRESSES.

ATTENTION THEN SHIFTS TO CONVECTION CHANCES TO THE WEST OF KHUT/KRSL
AND KICT THIS EVENING. WILL GO WITH VCTS NEAR THESE AREA AFTER 23Z
AND EXTEND IT UNTIL 06Z AS CONVECTION IS PROGGED TO MOVE ACROSS
MOST OF CENTRAL AND SOUTH KS DURING THE EVENING HOURS.  WILL ALSO
INCLUDE A TEMPO GROUP FOR SOME VARIABLE GUSTY WINDS AND REDUCE
VISIBILITIES TO MVFR WITH SOME STRONGER STORMS EXPECTED TO MOVE
ACROSS KHUT/KICT AREAS.

.PREV DISCUSSION... /ISSUED 1156 AM CDT MON MAY 26 2008/

UPDATE...

ANOTHER INTERESTING AFTERNOON UNFOLDING ACROSS THE AREA.

FIRST CONCERN IS CURRENT HEAVY RAINFALL ACROSS SOUTHEAST KANSAS.
THIS CONVECTION IS SUPPORTED BY SOME ISENTROPIC LIFT IN THE 315-325K
LAYER AND CONTINUES TO BACKBUILD OVER THE SAME LOCATIONS AS THIS
LIFT CONTINUES. SO CERTAINLY A LOCALIZED FLOODING THREAT AS THIS
CONVECTION WILL CONTINUE FOR AT LEAST A COUPLE OF MORE
HOURS...BEFORE SHORT TERM MODELS SUGGEST THAT THIS LIFT WILL
DIMINISH OR END AFTER 19Z.

FOCUS THEN QUICKLY SHIFTS OVER CENTRAL AND SOUTH CENTRAL KANSAS...AS
ATMOSPHERE RESETS ITSELF FOR ANOTHER ROUND OF CONVECTION LATE THIS
AFTERNOON INTO THIS EVENING.  CURRENT ANALYSIS SHOWS AN OUTFLOW
BOUNDARY DRAPED ACROSS CENTRAL KS INTO SOUTHWEST KS...WITH A DRYLINE
DRAPED SOUTH FROM DDC SOUTH INTO THE TX PANHANDLE.  SO AREAS JUST TO
THE WEST OF THE FORECAST AREA LOOKS AGAIN AN AREA OF CONCERN...AS
JET STREAK IN THE MID LEVEL FLOW COMES OUT OF THE SOUTHERN ROCKIES
INTO THE PLAINS FOR THE LATE AFTERNOON HOURS. VERY UNSTABLE AIRMASS
(3000-4000 J/KG) IS ALREADY IN PLACE JUST TO THE SOUTH AND EAST OF
THE ABOVE MENTIONED BOUNDARIES...WITH BULK SHEAR OF 30-35KT
SUFFICIENT FOR SEVERE THUNDERSTORMS TO DEVELOP.  CURRENT THOUGHTS
ARE THAT INITIATION WILL HOLD OFF UNTIL AROUND 21Z TO THE WEST OF
THE AREA AND MOVE EAST INTO CENTRAL AND SOUTH CENTRAL KANSAS AS THE
LATE AFTERNOON INTO THE EVENING PROGRESSES. SO SOME OF THE SAME
AREAS THAT WERE UNDER A SEVERE THREAT ON SUNDAY LOOK BE UNDER IT
AGAIN THIS EVENING. MAIN TORNADO THREAT LOOKS TO BE TO WEST OF THE
AREA...AS BULK SHEAR/EHI INCREASES OVER THIS AREA THIS EVENING.  BUT
CANNOT RULE OUT A SUPERCELL CAPABLE OF PRODUCING A TORNADO POSSIBLY
REACHING AREAS TO THE WEST OF HIGHWAY 14 BEFORE THREAT EVOLVES INTO
A LARGE HAIL AND DAMAGING WIND THREAT.

STORM TRAINING OVER THE SAME AREAS COULD ALSO LEAD TO A FLASH
FLOODING THREAT.

AVIATION...
12Z TAFS...THUNDERSTORMS ARE STILL GOING EAST OF INTERSTATE 135
THIS MORNING...AND THUNDERSTORM CHANCES WILL CONTINUE THROUGHOUT
THE DAY AND EVENING AT ALL TAF SITES. A FRONTAL BOUNDARY WILL LAY
ACROSS CENTRAL KANSAS THROUGH THE PERIOD. CONVECTION SHOULD MOVE
OUT OF THE AREA BY EARLY MORNING...LEAVING VFR CONDITIONS FOR THE
REMAINDER OF THE TAF PERIOD.

PREV DISCUSSION... /ISSUED 335 AM CDT MON MAY 26 2008/

DISCUSSION...

TODAY-TONIGHT:

RECORD IS GETTING OLD WITH ANOTHER ROUND OF SEVERE WEATHER BEHIND
AND ANOTHER ONE ON THE HORIZON. OUTFLOW FROM CURRENT ROUND HAS
PUSHED NEAR I-40 IN WESTERN OK. HOWEVER FLOW HAS ALREADY TURNED
BACK TO THE SOUTH TO THE NORTH OF THIS BOUNDARY...SO GOOD POTENTIAL
FOR MOISTURE TO FLY BACK NORTH ONCE AGAIN. AM A BIT CONCERNED THAT
ELEVATED PRECIPITATION WILL BREAK OUT ACROSS THE WESTERN HALF OF
FORECAST AREA THROUGH 1500 UTC...BUT WILL ONLY KEEP SLIGHT CHANCES FOR
THAT. MAIN SHOW ANTICIPATED TO START THIS AFTERNOON AS DECENT
SHORTWAVE CURRENTLY IN SOUTHERN ROCKIES EJECTS ACROSS PLAINS LATER
TODAY. SO IT APPEARS THERE WOULD BE ANOTHER OF SEVERE STORMS
INITIATING MOST LIKELY SOMEWHERE IN CENTRAL KS AND PROPAGATING
SOUTHEAST DURING THE EVENING AND OVERNGT HOURS...NOT ALL THAT
UNLIKE WHAT HAPPENED SUN EVENING...EXCEPT WITH BETTER UPPER
SUPPORT. BASED ON UNCERTAINTY WHERE STORMS WOULD INITIATE...OPTED
TO HOLD OFF ON THE FLOOD WATCH FOR NOW.

TUE-WED:

COURSE CONSIDERABLE UNCERTAINTY WITH FORECAST...WITH EVERYTHING
DEPENDENT ON HOW THINGS WILL PLAY OUT ON MON/MON NIGHT. ONE THING
THAT IS INTERESTING IS DECENT AGREEMENT BETWEEN OLD EUROPEAN CENTRE
FOR MEDIUM RANGE WEATHER FORECASTS MODEL/GLOBAL FORECAST SYSTEM
MODEL THAT COLDER AIR WILL BE OVERSPREADING THE AREA DURING THE DAY
ON TUE...WITH COOLER TEMPERATURES IN PLACE BY WED. THIS LEAVES A
RATHER LARGE BUST POTENTIAL FOR MAXES ON TUE. OPTED INCREASE
GRADIENT IN MAXIMUM TEMPERATURES ACROSS THE AREA ON TUE AND TRIM
TEMPERATURES A TAD ON WED. MINOR TWEAKS TO REMAINDER OF THE
FORECAST.

-HOWERTON

AVIATION...

MAIN CONCERNS ONCE AGAIN THE DEALING WITH POTENTIAL FOR MVFRR
CLOUDS TO DEVELOP IN MOIST UPSLOPE FLOW. STORMS WILL LIKELY AFFECT
ALL AERODROME FORCAST SITES SOMETIME DURING THE FORECAST
PERIOD...BUT DETAILS WILL BE DIFFICULT TO PIN DOWN. -HOWERTON

.DAY ONE...TODAY AND TONIGHT

THE SCATTERED THUNDERSTORMS THIS MORNING MAY OCCASIONALLY BE
STRONG...BUT ARE NOT EXPECTED TO BECOME SEVERE.

SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP SOMETIME THIS
AFTERNOON IN CENTRAL KANSAS...THEN TRAVERSE THE REMAINDER OF THE
AREA THIS EVENING AND OVERNIGHT. THE INITIAL THREAT WILL BE LARGE
HAIL...DAMAGING WINDS AND ISOLATED TORNADOES...MAINLY NORTH OF A
KINGMAN TO ELDORADO TO EUREKA LINE. THE STORMS WILL LIKELY
TRANSITION INTO A LINE DURING THE EVENING AND OVERNIGHT...WITH
THE PRIMARY THREAT BEING DAMAGING WINDS AND HEAVY RAIN. IF IT BECOMES
MORE CERTAIN THAT THE RICH MOISTURE WILL REACH THE FRONT AND
COMBINE WITH AFTERNOON SUNSHINE...THE THREAT FOR SIGNIFICANT
SEVERE WEATHER WILL GREATLY INCREASE.

LOCALLY HEAVY RAIN COULD ALSO LEAD TO SOME FLOODING...ESPECIALLY
OVER AREAS WHERE HEAVY RAIN HAS OCCURRED OVER THE WEEKEND.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

STRONG TO SEVERE THUNDERSTORMS ARE LIKELY AGAIN ON TUESDAY. THE
MOST LIKELY AREA FOR SEVERE THUNDERSTORMS IS SOUTHEAST OF A LINE

DEPENDENT ON WHAT HAPPENS MONDAY NIGHT.

THUNDERSTORMS WILL ALSO AFFECT THE AREA STARTING FRIDAY NIGHT AND
