Severe Thunderstorm Warning 274, NWS Springfield, MO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
320 PM CDT MON JUN 5 2006

.DISCUSSION...
MAIN FORECAST CONCERNS WILL DEAL WITH CONVECTIVE CHANCES TONIGHT
THROUGH TUESDAY.

CURRENTLY WATCHING A MCV TRACKING SOUTHEAST INTO FAR NORTHWEST
MISSOURI.  CONVECTION HAD FIRED IN ADVANCE OF THIS FEATURE FROM
NORTH OF KANSAS CITY INTO SOUTHERN IOWA.  EARLIER THOUGHT THIS UPPER
FEATURE WOULD BEGIN TO TAKE MORE OF A SOUTH/SOUTHEAST ROUTE...BUT
THIS HASNT TAKEN PLACE. LOOKS LIKE THE CIRCULATION MAY GRAZE OUR
FAR NORTHERN COUNTIES DURING THE EVENING. BY THE TIME THIS
CIRCULATION REACHES THOSE AREAS...INSTABILITY LOOKS TO BE LACKING AS
CURRENT SPC MESO-ANALYSIS SHOWS MUCAPES DROPPING OFF QUICKLY EAST OF
VERSAILLES.  TRENDS WILL NEED CONTINUED MONITORING TO SEE IF THE
NORTHERN CONVECTION CAN BUILD DOWN INTO CENTRAL MISSOURI IN THE NEXT
COUPLE OF HOURS. STILL CONCERNED ABOUT POSSIBLE DEVELOPMENT ACROSS
EASTERN KANSAS AND WESTERN MISSOURI...AS MUCAPES ARE IN EXCESS OF
1500 J/KG IN THESE LOCATIONS.  NEGATIVE FACTORS FOR DEVELOPMENT
INCLUDE THE BETTER FORCING MAY PASS TO THE NORTH...AND A WEAK CAP
IS IN PLACE WITH MLCIN VALUES OF -25 TO -75 J/KG.  CANT RULE OUT AN
ISOLATED SEVERE STORM OUT WEST LATE THIS AFTERNOON OR EVENING IF
SOMETHING DEVELOPS...AS THERE WOULD BE ENOUGH INSTABILITY AND NAM
0-6KM BULK SHEAR VALUES ARE IN EXCESS OF 30 KTS GENERALLY ALONG AND
WEST OF THE KANSAS BORDER.  ATTENTION THEN TURNS TO A CONVECTIVE
COMPLEX TONIGHT WHICH WILL DEVELOP ACROSS THE PLAINS.  A COLD FRONT
WILL CONTINUE TO PUSH SOUTHEAST ACROSS NEBRASKA TONIGHT. AS A
SIGNIFICANT UPPER WAVE TRACKS ACROSS THE NORTHERN PLAINS A LOW LEVEL
JET AND INCREASED MOISTURE TRANSPORT WILL DEVELOP OVER THE CENTRAL
U.S.  THE JET WILL INTERACT WITH THE FRONT TO TRIGGER A CONVECTIVE
COMPLEX ACROSS NEBRASKA THAT WILL PEEL SOUTHWARD TONIGHT.  CONCERNED
THAT THE BULK OF THE STORM ACTIVITY WILL STAY WEST OF THE AREA PER
CORFIDI VECTORS.  HOWEVER...THE LLJ WILL VEER WITH TIME SO KEPT HIGH
END CHANCE/LOW END LIKELY NORTHWEST OF A WARSAW TO JOPLIN LINE.  IF
A GOOD COLD POOL DEVELOPS...DAMAGING WINDS WOULD BE THE PRIMARY
THREAT WITH LARGE HAIL ALSO POSSIBLE.

TRICKY FORECAST IN STORE FOR TUESDAY WILL DEPEND ON TONIGHTS
ACTIVITY.  WILL LIKELY BE SOME LINGERING MORNING SHOWERS AND OR
STORMS ACROSS PARTS OF THE AREA.  IN ADDITION...THE FRONT WILL
LIKELY NOT BE THROUGH THE AREA BY AFTERNOON
THEREFORE...REDEVLOPMENT OF THUNDERSTORMS WOULD BE POSSIBLE IF
SUFFICIENT CLEARING OCCURS.  0-6KM SHEAR AGAIN WILL BE AROUND 30 KTS
SO ISOLATED TO WIDELY SCATTERED STRONG TO SEVERE WOULD BE POSSIBLE
IF ENOUGH INSTABILITY DEVELOPS.  DRIER AIR LOOKS TO FILTER INTO THE
AREA BY TUESDAY NIGHT.  HELD ONTO SOME LINGERING SMALL POPS OUT EAST
DURING THE EVENING...BUT MOST LOCATIONS SHOULD BE DRY.

MEAN UPPER PATTERN FOR THE FIRST HALF OF THE EXTENDED PERIOD WILL
HAVE A RIDGE PARKED OVER THE CENTRAL U.S.  DEPENDING ON THE EXACT
PLACEMENT OF THIS FEATURE...THE FORECAST AREA WILL LIKELY CONTINUE
TO AT LEAST BE ON THE FRINGE OF NORTHWEST FLOW.  ON WEDNESDAY...THE
GFS AND NAM BOTH SHOW A SIGNIFICANT UPPER WAVE RIDING THE PERIPHERY
OF THE RIDGE ACROSS ILLINOIS AND FAR EASTERN MISSOURI.  THE BULK OF
ANY PRECIP ASSOCIATED WITH THIS FEATURE WILL LIKELY STAY EAST OF THE
FORECAST AREA.  HOWEVER...SINCE EASTERN PORTIONS OF CENTRAL AND
SOUTH-CENTRAL MISSOURI MAY RECEIVE A GLANCING BLOW FROM THE
WAVE...20 TO 30 POPS WERE ADDED WEDNESDAY FOR THE EASTERN OZARKS.
RIDGE BEGINS TO BE SUPPRESSED SOUTHWARD AS THE DAY WEARS ON SATURDAY
WHICH WILL ALLOW FOR A MORE WEST TO EAST UPPER FLOW.  IN
ADDITION...A FRONTAL BOUNDARY MAY PUSH INTO THE REGION BY MONDAY AND
LOW POPS HAVE BE INSERTED INTO THE GRIDS TO ACCOUNT FOR THIS.  AS
FOR TEMPERATURES...HIGHS LOOK TO BE ABOVE NORMAL FOR EARLY JUNE
THROUGH THE PERIOD.  TEMPS WILL BE PARTICULARLY WARM THIS WEEKEND AS
850 MB TEMPS WILL RANGE FROM 20 TO 25 DEG C.  SHOULD SEE AT LEAST
SOME LOWER 90S ACROSS THE FORECAST AREA.

.AVIATION...
FOR 18Z TAFS...AVIATION CONCERNS IN THE NEXT 6 HOURS DEAL WITH
COMPLEX OF THUNDERSTORMS AND ASSOCIATED MCV IN SOUTHEAST NEBRASKA
EXPECTING TO DIVE SOUTHWARD ACROSS EASTERN KANSAS THIS AFTERNOON.
CURRENT INSTABILITY PARAMETERS INDICATED A PRONOUNCED CAP IN PLACE
WHERE THE HIGHEST PROBABILITY OF THUNDERSTORMS ARE EXPECTED THIS
AFTERNOON. THEREFORE...HAVE NOT PLACED ANY CONVECTION THROUGH 00Z
DUE TO THIS REASON. AFTER 00Z...KJLN WILL LIKELY BE UNDER THE GUN
FOR CONVECTION...BUT PLACEMENT WILL BE CRITICAL SO CONTINUE THE SAME
TREND WITH THUNDERSTORMS IN THE VICINITY. HAVE ADDED MVFR AND
THUNDERSTORMS FOR KJLN BY 10Z AND 15Z FOR KSGF DUE TO ANTICIPATED
THUNDERSTORM COMPLEX EXPECTED TO MOVE ACROSS THE REGION. LATER
SHIFTS WILL NEED TO UPDATE BASED ON CURRENT RADAR AND SATELLITE
TRENDS.
