AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
600 PM CDT TUE JUN 16 2009

.AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
MAIN AREA OF CONCERN IS SERN KS FOR CONVECTION POTENTIAL TONIGHT.
RESIDUAL OUTFLOW BOUNDARY DRAPED ACROSS NERN OK/SERN KS/FLINT
HILLS WITH DEEP LOW-LEVEL MOISTURE/INSTABILITY IN PLACE.
ATMOSPHERE REMAINS CAPPED BUT WITH 30KT SRLY LOW-LEVEL JET
DEVELOPING THIS EVE...ISENTROPIC LIFT/CONVERGENCE WITH THE JET MAY
INITIATE SCT TS IN THE FLINT HILLS/SERN KS. STORM MOTION WILL BE
EASTWARD AT 20-25KT...SO CNU COULD BE IMPACTED. FOR NOW WILL GO
WITH VCTS THIS EVE AT CNU GIVEN SCT COVERAGE EXPECTATION.
OTHERWISE...LEE LOW DEVELOPMENT IN ERN CO/WRN KS AND MID-LEVEL
WARMING SHOULD KEEP WED CAPPED WITH SOME GUSTY SOUTHERLY WINDS
MIDDAY INTO PM HOURS.

.PREV DISCUSSION... /ISSUED 325 PM CDT TUE JUN 16 2009/

DISCUSSION...
FORECAST HIGHLIGHTS OVER THE NEXT 7 DAYS WILL BE THUNDERSTORM
CHANCES AND HOT TEMPERATURES.

THUNDERSTORM CHANCES:
REMNANT OUTFLOW BOUNDARY CURRENTLY EXTENDS EAST/WEST ACROSS
NORTHEAST/NORTHERN OK...WHICH MERGES WITH A WEAK SYNOPTIC BOUNDARY
EXTENDING FROM WESTERN OK NORTHEAST THROUGH EASTERN KS. DESPITE
INCREASED UPPER RIDGING AND ASSOCIATED MID-LEVEL WARMING...STRONG
HEATING COUPLED WITH RICH BOUNDARY LAYER MOISTURE WILL RESULT IN
VERY STRONG INSTABILITY LATE THIS AFTERNOON/EVENING. CONVERGENCE IS
RATHER WEAK...BUT MAY PROVE STRONG ENOUGH FOR A FEW THUNDERSTORMS TO
FORM ALONG THESE BOUNDARIES LATE THIS AFTERNOON/EVENING. GIVEN THE
DEGREE OF INSTABILITY ALONG WITH AROUND 40 KT OF DEEP LAYER
SHEAR...ANYTHING THAT DEVELOPS WILL LIKELY BECOME SEVERE...CAPABLE
OF LARGE HAIL AND DAMAGING DOWNBURST WINDS. DESPITE THE POTENTIAL
FOR ROTATING UPDRAFTS...THINKING TORNADO THREAT WILL BE MINIMAL
GIVEN RELATIVELY WEAK LOW-LEVEL SHEAR. HOWEVER...TORNADO THREAT
COULD INCREASE ONCE LOW-LEVEL JET INCREASES AND BOUNDARY LAYER FLOW
BACKS FOR ANY SUSTAINED SUPERCELL THAT IS STILL GOING THIS EVENING.
GIVEN NO UPPER SUPPORT...ACTIVITY SHOULD DIMINISH BY MIDNIGHT...WITH
STORM CHANCES LIFTING NORTHEAST THROUGH THE NIGHT AS LOW-LEVEL JET
FOCUSES FARTHER NORTH.

COULD SEE A STRAY STORM OVER CENTRAL AND EASTERN KS WEDNESDAY
MORNING ALONG RETREATING 850-700MB WARM/MOIST ADVECTION ZONE. COULD
SEE A STAY STRONG/SEVERE STORM OR TWO REDEVELOP DURING THE LATE
AFTERNOON/EVENING HOURS ACROSS CENTRAL KS IN THE VICINITY OF THE
NORTHWARD RETREATING BOUNDARY. HOWEVER...BEST CHANCES SHOULD REMAIN
OVER NORTHERN KS AND NE ALONG/NORTH OF THE BOUNDARY.

THUNDERSTORM CHANCES WILL INCREASE FOR THURSDAY EVENING THROUGH
FRIDAY MORNING FROM NORTHWEST TO SOUTHEAST...AS A SEASONABLY STRONG
SHORTWAVE AND ASSOCIATED COLD FRONT PROGRESSES ACROSS THE CENTRAL
PLAINS. COULD BE LOOKING AT SEVERE WEATHER GIVEN THE EXPECTED
SYNOPTIC FORCING...SHEAR AND INSTABILITY. HEAVY RAINFALL AND
CONTINUED FLOODING CONCERNS COULD BE AN ISSUE AS WELL. STAY TUNED.

FOR SATURDAY AND BEYOND...CONFIDENCE IS FAIRLY HIGH THAT UPPER
RIDGING WILL BUILD ACROSS THE SOUTHERN/CENTRAL CONUS...WITH MOIST
SOUTHWEST FLOW ALOFT ACROSS THE WESTERN CONUS. THE PATTERN WOULD
SUGGEST MAINLY DRY CONDITIONS ACROSS THE FORECAST AREA DUE TO
PROXIMITY OF THE UPPER RIDGE. HOWEVER...THIS PATTERN WOULD FAVOR
AFTERNOON/EVENING THUNDERSTORMS DEVELOPING ACROSS THE WESTERN HIGH
PLAINS AND ROLLING EAST DURING THE EVENING AND OVERNIGHT
HOURS...WHICH COULD AFFECT PORTIONS OF CENTRAL KS DURING THE
NIGHTTIME HOURS AS LOW-LEVEL JET INTENSIFIES. PREDICTABILITY IS TOO
LOW AT THIS TIME THOUGH TO INSERT SLIGHT CHANCE POPS.

HOT/MUGGY TEMPERATURES:
WITH THE EXCEPTION FOR FRIDAY AND POSSIBLY SATURDAY (COOLER AIRMASS
BEHIND COLD FRONT)...HOT SUMMER WEATHER IS EXPECTED THROUGH THE NEXT
7 DAYS. DID NOT GO AS WARM AS THE NAM MODEL DUE TO EXPECTED
EVAPOTRANSPIRATION EFFECTS FROM RECENT HEAVY RAINS...ESPECIALLY OVER
THE NEXT FEW DAYS. HOWEVER...RICH LOW-LEVEL MOISTURE WILL ALLOW HEAT
INDICES TO WARM INTO THE UPPER 90S TO LOW 100S FOR WEDNESDAY AND
THURSDAY...ESPECIALLY ACROSS SOUTHERN AND EASTERN PORTIONS OF THE
FORECAST AREA. HOT TEMPERATURES WILL RETURN FOR SATURDAY/SUNDAY AND
BEYOND...AS UPPER RIDGE BUILDS BACK IN. NEAR TRIPLE DIGIT HEAT WILL
BE POSSIBLE...ESPECIALLY ACROSS WESTERN AND SOUTHWEST PORTIONS OF
THE AREA. EASTERN PORTIONS OF THE AREA WILL BE COOLER DUE TO HIGHER
BOUNDARY LAYER MOISTURE...BUT MAY HAVE ISSUES WITH TRIPLE DIGIT HEAT
INDICES. STAY TUNED.

KLEINSASSER

AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
THERE ARE A COUPLE SURFACE BOUNDARIES AROUND THE AREA TODAY...ONE
STRETCHING FROM MANHATTAN KS TO NEAR KHUT...AND THE OTHER ACROSS
NORTHERN OKLAHOMA. SOME SCATTERED THUNDERSTORMS WILL BE POSSIBLE
SOUTHEAST OF THE BOUNDARY ACROSS CENTRAL KANSAS LATE THIS
AFTERNOON AND TONIGHT...HOWEVER THE LIKELIHOOD OF THUNDERSTORMS AT
ANY ONE TAF SITE IS NOT HIGH ENOUGH TO INCLUDE IN THE FORECAST AT
THIS TIME. OTHERWISE...WINDS INCREASE ON WEDNESDAY. VFR CONDITIONS
EXPECTED THROUGH THE TAF PERIOD...ASIDE FROM DURING ANY
THUNDERSTORM THAT COULD AFFECT A TAF SITE.
