AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1235 AM CDT TUE APR 22 2008

.UPDATE...

CURRENTLY...COLD FRONT HAS BECOME QUASI STATIONARY OVER EASTERN
KANSAS EXTENDING FROM JUST NORTH OF STJ TO NEAR TOP...STRETCHING
TO THE SSW TO NEAR OKC. WARM SECTOR AHEAD OF THIS BOUNDARY IS
ENERGIZED...WITH LAPS MLCAPE VALUES BETWEEN 1500 AND 2000 J/KG.
CIN...HOWEVER...REMAINS RATHER ROBUST WITH MOST AREAS AT OR ABOVE
80 J/KG EXCEPT FOR RIGHT ALONG THE SFC BOUNDARY. 00Z KSGF SOUNDING
CONFIRMS THAT A RATHER STOUT CAP (2C) REMAINS IN PLACE IN THE
800MB TO 750MB LAYER.

IT LOOKS LIKE OUR AREA WILL NEED TO WAIT FOR FORCING FROM A WEAK
SHORTWAVE MOVING OVER WESTERN KS AT THIS TIME. SHOULD SEE AN
INCREASE IN CONVECTIVE DEVELOPMENT TO OUR WEST ALONG THE COLD FRONT
THIS EVENING AS THIS ENERGY SPREADS OVER THE SFC BOUNDARY. WILL
RELY ON MID LEVEL COOLING ASSOCIATED WITH THE SHORTWAVE TO NEGATE
THE CAPPING INVERSION ALOFT. AN UPDRAFT OR TWO WILL TRY TO GET
GOING THIS EVENING...BUT IT LOOKS LIKE MOST AREAS WILL REMAIN DRY
UNTIL AFTER MIDNIGHT.

AFTER MIDNIGHT...CONVECTION SHOULD BEGIN TO ENCROACH ON THE
WESTERN CWA. IT APPEARS THAT THE BETTER CHANCES FOR STORMS WILL BE
OVER THE WESTERN HALF OF THE CWA...ROUGHLY ALONG AND WEST OF
HIGHWAY 65...GIVE OR TAKE. SEVERE POTENTIAL REMAINS CONDITIONAL.
WITH THE CAP HOLDING ON MUCH OF THE EVENING...WE WILL LOSE OUR
DAYTIME HEATING. DEWPOINTS SHOULD RISE A FEW MORE DEGREES...INTO
THE LOWER 60S...AS A 25 TO 30KT LOW LEVEL JET DEVELOPS AHEAD OF
THE SFC FRONT. THIS SHOULD BE GOOD ENOUGH TO SUPPORT MLCAPE VALUES
OF AROUND 1000 J/LG...MAYBE A LITTLE HIGHER ALONG THE SFC FRONT.
DEEP LAYER SHEAR LOOKS TO BE MARGINAL...AROUND 25KT. SEVERE RISK
WILL LIKELY BE LINKED TO THE QUALITY OF STORMS THAT DEVELOP ALONG
THE COLD FRONT ACROSS KANSAS THIS EVENING. IF A DECENT COLD POOL
CAN DEVELOP...WIND GUSTS AND MARGINALLY SEVERE HAIL WILL BE OUR
MAIN HAZARDS. WILL CONTINUE TO MONITOR THE DEVELOPMENT AND
PROGRESS OF THIS ACTIVITY. OTHERWISE...MULTICELL CLUSTERS WILL
LIKELY BE THE CONVECTIVE MODE GIVEN MARGINAL DEEP LAYER SHEAR.
WITH THIS ACTIVITY MARGINALLY SEVERE HAIL WILL BE THE PRIMARY
HAZARD WITH AN OUTSIDE SHOT AT LOCALLY DAMAGING WINDS.

WILL UPDATED THE FORECAST TO LOWER POPS THIS EVENING...DELAY MOST
OF THE TSRA ACTIVITY UNTIL AFTER MIDNIGHT AND REFRESH THE HWO.

.DISCUSSION...

FORECAST CHALLENGES DEAL WITH SEVERE WEATHER POTENTIAL TONIGHT
THROUGH TUESDAY AND PRECIPITATION CHANCES THROUGHOUT THE WEEK.

SHORT TERM (TODAY THROUGH WEDNESDAY NIGHT)...

CURRENTLY...COLD FRONT EXTENDS FROM EXTREME EASTERN NEBRASKA
THROUGH SOUTH CENTRAL KANSAS BACK INTO THE TEXAS PANHANDLE THIS
AFTERNOON. DEWPOINTS OVER EASTERN OKLAHOMA...INTO EASTERN KANSAS
INTO THE LOW TO MID 60S WITH UPPER 50S ACROSS WESTERN MISSOURI. 12Z
SGF SOUNDING THIS MORNING SHOWED A VERY STRONG CAPPING INVERSION
FROM AROUND 800MB TO 770MB...SO CONVECTION HAS YET TO BEGIN.
SEVERE WEATHER WILL BE HIGHLY CONDITIONAL ON THIS CAPPING
INVERSION BREAKING THIS EVENING.

COLD FRONT FORECAST TO APPROACH EXTREME SOUTHEAST KANSAS LATE THIS
EVENING. LATEST RUC SOUNDINGS FOR EXTREME SOUTHEAST KANSAS KEEPS
CAPPING INVERSION IN PLACE THROUGH AT LEAST THROUGH 03Z. DO
BELIEVE AS THE FRONT MOVES IN...WE SHOULD SEE THIS CAP WEAKENING
OUT WEST. THAT AND THE GFS SHOWS A 25-30KT 925MB JET SETTING UP
THAT SHOULD PROVIDE SOME FOCUS FOR LIFT. BY 06Z...CAP ON THE RUC
SOUNDING DEFINITELY WASHED OUT AND CONVECTION SHOULD REALLY GET
GOING. SB CAPES OUT WEST AT AROUND 2200 J/KG AND SOUNDING SHOWING A
VERY FAVORABLE SOUNDING FOR LARGE HAIL. 0-3KM HELICITIES RIGHT
AROUND 200M2/S2...SO WENT AHEAD AND KEPT CHANCE OF ISOLATED
TORNADOES IN THIS AFTERNOONS HWO. CAP IS A LITTLE STRONGER EAST
NEAR SPRINGFIELD AND THREAT FOR THIS AREA SHOULD BE MORE IN LINE
OF LARGE HAIL AND DAMAGING WINDS. EVENING SHIFT WILL NEED TO
CLOSELY MONITOR EVENTS THROUGH THE EVENING AND HAZARDS MAY NEED TO
BE EXTENDED FURTHER EAST.

COLD FRONT SLOWLY MOVES EAST TUESDAY MORNING. BY 18Z...SURFACE LOW
FORECAST ON GFS PROGGED TO BE OVER NORTHEAST MISSOURI...WITH
TRAILING COLD FRONT RIGHT ALONG OSAGE BEACH TO SPRINGFIELD TO
JOPLIN LINE AT THAT TIME. OUT AHEAD OF THE FRONT...GFS FORECAST
CAPES OVER SOUTHEAST AND EAST CENTRAL MISSOURI RIGHT AROUND 1500
J/KG...SO COMMUNITIES GENERALLY SOUTH OF THE INTERSTATE 44
CORRIDOR WILL BE IN THE BULLSEYE FOR SEVERE WEATHER DURING THE
AFTERNOON. AGAIN...SHEAR NOT ALL THAT GREAT FOR A TORNADIC
THREAT...AND LARGE HAIL AND DAMAGING WINDS ARE EXPECTED TO BE THE
MAIN THREATS. FRONT CLEARS THE CWA TO THE EAST AND SOUTH TUESDAY
EVENING...WITH FRONT HANGING UP OVER NORTHERN ARKANSAS EARLY
WEDNESDAY MORNING. THIS FRONT WILL BE THE FOCUS FOR ADDITIONAL
RAINFALL LATER IN THE WEEK. WITH EASTERLY FLOW WEDNESDAY...DO
BELIEVE CWA SHOULD BE MOSTLY DRY.

CLAYCOMB

LONG TERM (THURSDAY THROUGH MONDAY)...

A HIGH AMPLITUDE BUT FAIRLY PROGRESSIVE UPPER FLOW PATTERN IS
EXPECTED FOR MUCH OF THIS TIME. QUITE A FEW DISCREPANCIES BETWEEN
THE 12Z GFS AND 00Z ECMWF DURING THIS TIME FRAME. GENERALLY
FOLLOWED THE ECMWF AND HPC GUIDANCE. MAIN COMMON FEATURES EARLY
ARE A TROUGH OVER WESTERN NOAM...BUT MAIN DIFFERENCES CONCERN HOW
SHORTWAVES EMBEDDED IN THE FLOW ARE HANDLED. A LEAD SHORTWAVE
FEATURED BY THE ECMWF MOVES NORTHEAST THROUGH KS/MO EARLY THU
MORNING FOLLOWED BY THE MAIN/STRONGER WESTERN SHORTWAVE AND COLD
FRONT APPROACHING THE REGION FRI AND MOVING THROUGH EASTERN KS/MO
LATE FRI NIGHT EARLY SAT MORNING. THE THU/FRI TIME PERIOD WOULD
SEEM TO BE THE BEST OVERALL CHANCES FOR RAIN/TSTMS.

BIG/HUGE DIFFERENCES IN THE MODELS DEVELOP WITH PLACEMENT OF A
NORTHWEST FLOW UPPER SYSTEM...WITH THE GFS MUCH FARTHER SOUTH AND
WEST WITH PLACEMENT VERSUS THE ECMWF...PROBABLY ON THE ORDER OF 1000
MILES BY MONDAY AFTERNOON. THE GFS PLACES A CLOSED LOW OVER KS/OK BY
00Z TUE WHILE THE ECMWF HAS A STRONGER CLOSED LOW OVER OHIO. THIS IS
WHERE I PUNTED AND FOLLOWED FOLLOWED HPC GUIDANCE MORE CLOSELY.
CONFIDENCE IS FAIRLY LOW EARLY NEXT WEEK.

.AVIATION...

FOR THE 06Z TAF PACKAGE...PRIMARY FORECAST CHALLENGE OVER THE TAF
PERIOD DEALS WITH THUNDERSTORM POTENTIAL ALONG A SLOW MOVING FRONT
CURRENTLY LOCATED OVER EASTERN KANSAS. AHEAD OF THE FRONT VFR
CONDITIONS WILL BE THE RULE...WITH MVFR CONDITIONS POSSIBLE WITHIN
ANY SHRA/TSRA ACTIVITY THAT IS BEGINNING TO DEVELOP ALONG THE
FRONT ACROSS EASTERN KANSAS. SHRA/TSRA WILL LIKELY CONTINUE TO DEVELOP
ALONG THE FRONT AS IT MOVES EAST INTO THE TAF SITES
OVERNIGHT...FIRST AT THE KJLN SITE OVER THE NEXT FEW HOURS THEN
INTO THE KSGF NEAR DAY BREAK. MVFR CONDITION WILL CONTINUE TO BE
POSSIBLE WITH ANY SHRA/TSRA THROUGH TUESDAY MORNING. THE COLD
FRONT SHOULD PASS THROUGH BOTH TERMINALS AROUND MIDDAY...WITH
IMPROVING CONDITIONS IN THE EARLY AFTERNOON.
