AREA FORECAST DISCUSSION...UPDATED AVIATION FOR 00Z TAFS
NATIONAL WEATHER SERVICE SPRINGFIELD MO
534 PM CDT WED AUG 24 2005

.DISCUSSION...

MAIN CONCERN IS HEAVY RAINFALL POTENTIAL. SECONDARY CONCERN IN THE
SHORT TERM IS ALSO ISOLATED SEVERE WEATHER POTENTIAL.

SEEING A SIMILAR SET UP THAT WE SAW 24 HOURS AGO...WITH OLD
MESOSCALE CONVECTIVE VORT MOVING INTO WESTERN MO. SURFACE HEATING IS
ALLOWING TEMPERATURES TO RECOVER WELL BACK INTO THE 80S. RESULTANT
INSTABILITY MAY ALLOW SOME STORMS TO DEVELOP OVER THE
AREA...ESPECIALLY THE SOUTHERN HALF OF THE AREA. ANOTHER BETTER
LOOKING UPPER SYSTEM IS ALSO MOVING THROUGH SOUTH CENTRAL KANSAS AT
THIS TIME. THIS NEXT SYSTEM IS MOVING INTO AN AXIS OF LOW-MID 70
DEWPOINTS...TEMPS NEAR 90 DEG F OVER SE KS...AND A BACKED SFC FLOW.
CUMULUS BUILDING IN SOUTHEAST KS. 100MB MIXED LAYER CAPES ABOUT
1000-1500 J/KG OFF THE RUC...BUT SUSPECT THEY ARE A BIT HIGHER IN
PORTIONS OF SOUTHEAST KS NEAR KCFV. WILL NEED TO CONTINUE TO WATCH
FOR SEVERE POTENTIAL...ESPECIALLY IN THE SW CORNER OF THE FORECAST
AREA FOR THE NEXT FEW HOURS.

FLOOD POTENTIAL EXISTS FOR TONIGHT. WENT PRIMARILY WITH THE
GFS...MINUS THE CONVECTIVE FEEDBACK. MODERATE LOW LEVEL JET SHOULD
AGAIN SET UP OVER OK/KS AND GRADUALLY VEER INTO THE AREA LATE
TONIGHT AND THURSDAY MORNING. PRECIPITABLE WATER (PWAT) VALUES
SHOULD INCREASE WITH INCREASING LOW AND MIDLEVEL MOISTURE TRANSPORT.
POINT SOUNDINGS FROM THE BOTH THE GFS AND NAM INCREASE PWATS TO
AROUND 2.00 INCHES THURSDAY MORNING. 85H MOISTURE TRANSPORT IS
MAXIMIZED OVER EAST CENTRAL KS/WEST CENTRAL MO LATE TONIGHT THU
MORNING. LIFT MAY BE ENHANCED BY 300/250MB JET STREAK PROGGED TO
EXTEND FROM NE KS INTO IA LATE TONIGHT AND WEAK SHORTWAVE MOVING
THROUGH THE 500MB FLOW FROM THE HIGH PLAINS INTO NORTH CNTRL KS BY
EARLY THURSDAY MORNING. ALL-IN-ALL PROBABLY NOT A SLAM DUNK IN TERMS
OF WHERE EXACTLY THE HEAVIEST RAIN WILL OCCUR...BUT ENOUGH EVIDENCE
EXISTS TO GO AHEAD WITH A FLOOD WATCH FOR NORTHWEST/NORTHERN
PORTIONS OF THE FORECAST AREA. THE WATCH AREA IS BASED GREATLY WHERE
MOISTURE TRANSPORT IS PROGGED TO BE MAXIMIZED.

WEAKENING CONVECTION WILL AFFECT THE AREA DURING THE DAY
THURSDAY...BUT SOME RECOVERY OF SURFACE TEMPERATURES IS EXPECTED IN
THE AFTERNOON BEHIND THE WEAKENING SYSTEM. COULD SEE ANOTHER SYSTEM
AFFECT EASTERN KS WESTERN MO FRIDAY MORNING AS WELL. WE MAY ALSO SEE
STRONG TO SEVERE DIURNAL CONVECTION ON THE FRINGES OF THE MESOSCALE
SYSTEMS...ESPECIALLY ON FRIDAY IF MAIN CONVECTIVE RAINFALL AND
DEBRIS CLOUDS REMAIN TO OUR NORTH ON FRIDAY (OR TOMORROW FOR THAT
MATTER). PICTURE BY THAT TIME IS GETTING TO DIFFICULT TO
DISCERN...OTHER THAN TO KEEP RAIN/THUNDERSTORM CHANCES IN THE
FORECAST.

HIGH AMPLITUDE...BUT PROGRESSIVE MIDLEVEL FLOW IN SOUTHERN
CANADA/NORTHERN U.S. WILL CONTINUE...WITH THE SUBTROPICAL RIDGE
SUPPRESSED TO THE SOUTH. SHORTWAVES WILL CONTINUE TO AFFECT THE
AREA...THROUGH MUCH OF THE EXTENDED PERIODS. COLD FRONT ASSOCIATED
WITH SYSTEM NOW SLOWLY TRAVERSING SOUTHERN CANADA.DAKOTAS WILL MOVE
THROUGH THE AREA LATE FRIDAY NIGHT/SATURDAY SO WILL MAINTAIN RAIN
CHANCES THROUGH THE DAY SATURDAY. ANOTHER STRONG SYSTEM WILL MOVE
ONSHORE INTO BRITISH COLUMBIA SATURDAY NIGHT AND ALBERTA/PACIFIC
NORTHWEST BY MONDAY. RIDGE BUILDS AHEAD OF THIS SYSTEM OVER THE
PLAINS...BUT BOTH THE ECMWF AND GFS CONTINUE TO MOVE A WEAKNESS IN
THE 500MB FLOW THROUGH THE AREA MONDAY. WILL CONTINUE WITH SLIGHT
POPS FOR MONDAY...OTHERWISE WENT DRY IN THE EXTENDED PERIODS
SUNDAY-WEDNESDAY.

THANKS FOR THE COORDINATION LSX...EAX...TOP...ICT.

.AVIATION...
SOME CONVECTION INITIATING ALONG A BOUNDARY FROM CARTHAGE TO
SELIGMAN AS OF 2230Z.  BOUNDARY IS SHIFTING WESTWARD AND IF TREND
CONTINUES WILL PUSH THROUGH THE JLN AREA IN COUPLE OF HOURS.  SO
HAVE ADDED A TEMPO TSRA GROUP TO THE JLN TAFS FOR EARLY EVENING.
CONVECTIVE CHANCES LOOK TO INCREASE OVERNIGHT AS A SHORTWAVE PUSHES
INTO THE AREA.  HAVE THROWN IN A TEMPO GROUP FOR BOTH SGF/JLN FOR
TSRA AFTER 08Z.

THESE STORMS MAY PRODUCE WIND GUSTS OF 50 TO 60 MPH.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

THURSDAY MORNING. SCATTERED THUNDERSTORMS WILL ONCE AGAIN BE
POSSIBLE ON FRIDAY AND SATURDAY. SOME STORMS MAY BE SEVERE DEPENDING
ON THE AVAILABLE INSTABILITY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED THROUGH TONIGHT BECAUSE OF THE
RELATIVELY ISOLATED NATURE OF THE SEVERE WEATHER HAZARDS.
HOWEVER...SPOTTERS ARE URGED TO REPORT RAINFALL TOTALS AND FLOODING
TO THE NATIONAL WEATHER SERVICE.
