AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
119 PM CST WED NOV 5 2008

.DISCUSSION...

SYNOPSIS...12Z UPPR AIR ANLYS INDCD POWERFUL UPPR LVL SYSTEM DIVING
THRU UT AND CO ASSOCIATED WITH A 100 M H5 HEIGHT FALLS AT KDNR AND A
125 KT H3 JET ON THE BACKSIDE OF THE SYSTEM. MODIFIED GULF MOISTURE
CONTD TO STREAM NWD INTO THE CNTRL PLAINS WITH A +12 C DEWPOINT AS
FAR NWD AT KAMA. 18Z SFC ANLYS INDCD LO PRES OVR SE SD WITH CDFNT
THRU CNTRL NEB INTO CNTRL KS. DRYLINE EXTNDD FM CDFNT ARND KSLN SWD
INTO CNTRL OK.

FORECAST...MAIN FORECAST CONCERN OVR THE FIRST 12 HOURS WL BE SVR
WX. FORECAST REASONING HAS CHANGED LITTLE TODAY. POTENT UPPR LVL
SYSTEM IS PROGGED TO MOV INTO KS/NEB THIS EVNG AND CLOSE OFF. STG
SRLY LO LVL FLOW AHEAD OF THE SYSTEM WILL CONT INTO THE EVNG HOURS
AND WL MAKE LAST MINUTE CALL IF CONT THE WND ADVRY THRU 6 PM OR NOT.
NEVERTHELESS...EXPECT BRZY/WNDY CONDS THRU THE EVNG. TWO AREAS WL BE
MONITORED FOR TSRA DVLPMNT THRU THE AFTN/EVNG. FIRST WE SHOULD SEE
TSRA DVLP ALNG THE CDFNT FM ERN NEB TO CNTRL KS. GIVEN THE LINEAR
FORCING ASSOCIATED WITH THE FNT AND THE ORIENTATION OF THE SHEAR
VECTOR ALNG THE FNT...WHLD EXPECT A SQUALL LINE TO QUICKLY DVLP. 12Z
TOP RAOB INDCD STEEP MID LVL LAPSE RATES ABOVE THE EML AND THUS SCT
MARGINALLY SVR HAIL WL BE POSSIBLE WITH THIS ACTIVITY ALNG WITH STG
WNDS GIVEN THE ENVIRONMENTAL LO LVL WND ASSOCIATED WITH THE SYSTEM.
OTHER AREA OF POSSIBLE DEVELOPMENT WILL BE OVER SOUTH CENTRAL KS AND
NRN OK. HERE THE ORIENTATION OF THE SHEAR WITH THE SFC FORCING WL
ALLOW FOR A DISCRETE SUPERCELL OR TWO DURING THE LATE AFTN AND EVNG.
THE QUESTION HERE WILL BE WILL THAT ACTIVITY TO BE ABLE TO MAKE IT
INTO OUR SRN CWA BEFORE THE SQUALL LINE OVERTAKES IT? THIS WILL CONT
TO BE MONITORED THRU THE AFTN...BUT MAIN ACTIVITY SHLD STAY TO THE
SOUTH OF OUR FA. IF THIS ACTIVITY WERE ABLE TO MAKE IT INTO OUR SRN
CWA...THERE WOULD BE AN ISOLATED TORNADO THREAT. OTHERWISE THE MAIN
THREAT FOR US SHLD BE LARGE HAIL AND SOME WIND WITH THE CONVECTIVE
LINE. THE MAIN LINE OF ACTIVITY SHLD START TO PUSH E OF THE FA AFTER
MIDNIGHT AND WL END POPS FM W TO E AT THAT TIME. MID LVL CIRCULATION
IS THEN EXPECTED TO SLOWLY MOV EWD ACRS THE CNTRL AND NRN PLAINS.
ATTM IT APPEARS THAT MOST OF THE SHOWER ACTIVITY WL REMAIN TO THE
NORTH OF THE FA. SOME OF THIS MIGHT AFFECT NE KS ON FRI THOUGH AS
SYSTEM STARTS TO SHIFT A LITTLE FARTHER SEWD INTO SRN IA. OTHERWISE
WE ARE JUST EXPECTING MUCH COLDER TEMPERATURES THROUGH THE REST OF
THE WEEK WITH COLD NW FLOW. MAY BE CLOSE TO WND ADVRY CRITERIA OVR
N-CNTRL KS ON THUR AS SFC LOWS CONTS TO DEEPEN AND PRES GRADIENT
INCREASES...BUT GIVEN THE FIRST PERIOD CONCERNS WL HOLD OFF ON ANY
SECOND PERIOD ADVRY.

EXTENDED...NEXT CONCERN WL BE SYSTEM DROPPING INTO THE CNTRL PLAINS
FM SUN INTO TUES. MODELS DIFF ON THE LATITUDE OF THIS SYSTEM AND
ASSOCIATED PRECIP. WL PREFER A BLEND OF THE EC/GFS ATTM WHICH WLD
TARGET OUR CNTRL AND SRN CWA WITH THE HIGHEST POPS. WL CONT TO
MENTION A MIX OF RA/SN ON MON NIGHT AS SOUNDINGS GET CLOSE TO
COOLING OFF THE LOWEST LEVELS FOR A POSSIBLE SN SOUNDING. OTHERWISE
WLD EXPECT MOST OF THE PRECIP TO BE SHOWERS. WL DRY THINGS OUT
STARTING ON TUE NIGHT...BUT COOL TMPS LOOK TO CONT THRU THE END OF
THE PERIOD.

&&

.AVIATION...

MAIN ISSUE FOR THIS SET OF TAFS IS THE PASSAGE OF THE STRONG COLD
FRONT AND ASSOCIATED CONVECTION. THOUGHTS ARE TO BRING COLD FRONT
THROUGH AFTER 00 UTC WITH CONVECTION ALONG AND JUST BEHIND FRONT.
LEFT MVFR CONDITIONS WITH FRONTAL PASSAGE BUT COULD SEE BRIEF IFR IN
THUNDERSTORM BUT AM UNSURE OF EXACT TIMING.
