AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
SOLE FOCUS IS ON TSRA SCT ALONG A COLD FRONT THAT IS SAGGING SE OVER
EXTREME SC & SE KS THIS EVENING. WITH GREATEST INSTABILITY EXISTING
OVER COWLEY & WRN CHAUTAUQUA COUNTIES GREATEST POTENTIAL FOR STRONG
& POSSIBLY SVR TSRA WILL NOT AFFECT KICT OR KCNU TERMINALS THROUGH
24/03Z. HAVE LIMITED "VCTS" ASSIGNMENT TO KCNU WHERE COLD FRONT &
ASSOCIATED TSRA ARE SITUATED JUST NW-N OF THIS TERMINAL BUT MAKING
VERY SLOW S-SE PROGRESS TOWARD THE TERMINAL. OTHERWISE ALL 5

PREV DISCUSSION... /ISSUED 320 PM CDT WED JUN 23 2010/

DISCUSSION...

FORECAST HIGHLIGHTS FOCUS AROUND STRONG/SEVERE THUNDERSTORM CHANCES
THIS AFTERNOON/EVENING ACROSS MAINLY SOUTHEAST KS.

STRONG COLD FRONT IS CURRENTLY PROGRESSING SOUTHEAST ACROSS THE
AREA...STRETCHING FROM JUST WEST OF KANSAS CITY SOUTHWESTWARD TO
JUST NORTHWEST OF WICHITA...AND INTO WESTERN OK. CUMULUS ALONG FRONT
IS FAIRLY FLAT PER VISUAL OBSERVATIONS...EVIDENCE OF A STRONG CAP
STILL IN PLACE INHIBITING THUNDERSTORM DEVELOPMENT.
HOWEVER...CONTINUED AFTERNOON HEATING IN CONCERT WITH THE STRONG
FRONTAL FORCING AND APPROACHING WEAK MID-LEVEL COOLING FROM THE
NORTHWEST SHOULD ALLOW AT LEAST ISOLATED TO WIDELY SCATTERED
THUNDERSTORMS TO EVENTUALLY DEVELOP BY 4-6 PM...MAINLY
EAST/SOUTHEAST OF A LINE EXTENDING FROM EMPORIA TO WICHITA TO
HARPER. VERY UNSTABLE AIRMASS OF 3000-4000 J/KG MLCAPES IN PLACE
AHEAD OF THE FRONT...WITH RELATIVELY WEAK WIND SHEAR OF 20-30
KTS...SO AM ANTICIPATING MAIN STORM MODE TO BE MULTI-CELL...WITH THE
MAIN THREATS BEING HAIL UP TO PING PONG/GOLFBALL SIZE AND DOWNBURST
WINDS UP TO 70 MPH...ALONG WITH TORRENTIAL RAINFALL AND LOCALIZED
FLOODING. THINKING LANDSPOUT THREAT WILL BE FAIRLY LOW GIVEN LOW
AMOUNTS OF LOW-LEVEL CAPE. SEVERE THREAT SHOULD DIE OFF BY 9-10 PM
OR SO. HOWEVER...THREAT FOR LINGERING ISOLATED TO WIDELY SCATTERED
THUNDERSTORM ACTIVITY SHOULD CONTINUE ALL NIGHT ACROSS FAR SOUTHERN
KANSAS...AS WEAK LOW-LEVEL JET IMPINGES ON STALLING FRONTAL
BOUNDARY. ISOLATED ACTIVITY COULD LINGER THROUGH THURSDAY ACROSS FAR
SOUTHERN KANSAS.

THE NEXT CHANCE FOR THUNDERSTORMS MAY ARRIVE FOR THE SATURDAY
NIGHT-SUNDAY NIGHT TIMEFRAME...AS SHORTWAVE ENERGY PROGRESSES ACROSS
THE NORTHERN PLAINS...DRAGGING A COLD FRONT SOUTHEAST ACROSS THE
CENTRAL PLAINS. LOOKS LIKE A TYPICAL HIGH CAPE/LOW SHEAR SUMMER
SCENARIO ACROSS THE CENTRAL PLAINS...SO STRONG TO AT LEAST
MARGINALLY SEVERE STORMS LOOK POSSIBLE.

TEMPERATURES WILL COOL TO NEAR NORMAL VALUES FOR THURSDAY IN WAKE OF
THE COLD FRONT...WITH HIGHS UPPER 80S-LOW 90S AND LOWER DEWPOINTS.
HOWEVER...THE SUMMER HEAT/HUMIDITY RETURNS FOR FRIDAY-SATURDAY AS
SOUTHERLY FLOW COMMENCES AHEAD OF THE NEXT SHORTWAVE TROUGH. COULD
ONCE AGAIN BE FLIRTING WITH HEAT ADVISORY CRITERIA THESE TWO
DAYS...ESPECIALLY EAST OF THE I-135/I-35 CORRIDORS.

DESPITE A MASSIVE RIDGE BUILDING ACROSS THE WESTERN/CENTRAL CONUS BY
LATE WEEKEND...SOMEWHAT COOLER WEATHER IS ANTICIPATED FROM SUNDAY
INTO EARLY/MID NEXT WEEK IN WAKE OF THE WEEKEND SYSTEM. AMOUNT OF
COOLING WILL DEPEND ON WHICH MODEL SOLUTION VERIFIES. ECMWF WOULD
SUGGEST READINGS IN THE 80S FOR MOST LOCATIONS BY EARLY/MID NEXT
WEEK WITH A DEEPER EASTERN CONUS LONGWAVE TROUGH. THE GFS WOULD
SUGGEST READINGS A BIT WARMER IN THE UPPER 80S TO 90S...WITH A
NOT-AS-AMPLIFIED EASTERN CONUS TROUGH. HOWEVER...REGARDLESS OF
WHICH SOLUTION VERIFIES...AFTERNOON HEAT INDICES SHOULD BE MUCH
LESS THAN CURRENT READINGS...WITH GFS/ECMWF/HPC PROGGED DEWPOINTS
IN THE 50S AND 60S.

ADK

AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

DATA ANALYSIS AT 1730Z...A COLD FRONT EXTENDED FROM KPTT-KMPR-
KMHK. CU HAVE DEVELOPED ALONG THIS FRONT AND EXPECT CONVECTION TO
DEVELOP BY 20Z NEAR THE I-35 CORRIDOR. STORMS HAVE THE POTENTIAL
AFFECT KICT AND KCNU THIS AFTERNOON AND EVENING. DO NOT ANTICIPATE
ANY CONDITIONS LESS THAN VFR WITH THE EXCEPTION OF IN THE VICINITY
OF THE STRONG THUNDERSTORMS WHERE CIGS AND VSBYS COULD BE MVFR.

BEHIND THE FRONT THE WINDS SWITCH FROM SOUTH TO NORTHWEST AND
INCREASE TO 15-20 KNOTS WITH GUSTS TO 25 KNOTS. THESE CONDITIONS
WILL ADVANCE INTO THE AREA ONCE THE FRONT PASSES AND THE STORMS
MOVE OUT. STORMS SHOULD MOVE OUT THE AREA BY 03Z WITH SKIES
CLEARING.
