AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
230 AM CDT WED SEP 1 2010

.DISCUSSION...

MAIN FOCUS WILL BE WITH CONVECTIVE PRECIPITATION CHANCES THROUGH
THURSDAY NIGHT AND TEMPERATURES BEHIND THE FRONT FRIDAY INTO THE WEEKEND.

CONVECTIVE COMPLEX DEVELOPED DURING THE EVENING ACROSS NORTHERN
MISSOURI AND THIS HAS TRACKED EAST/SOUTHEAST INTO FAR NORTHERN
SECTIONS OF THE CWA EXTENDING NORTHWARD INTO NORTHEAST MISSOURI
EARLY THIS MORNING. OUTFLOW HAD OUTRUN THE MAIN AREA OF CONVECTION
EARLIER BUT HELPED TO INITIATE ADDITIONAL CONVECTION BETWEEN 11 PM
AND MIDNIGHT. A NEW OUTFLOW HAS STARTED TO PUSH SOUTH OF THE MAIN
AREA OF CONVECTION BUT SHOULD MOVE INTO A LESS FAVORABLE AREA
FURTHER SOUTH FOR MORE DEVELOPMENT WITH LESS INSTABILITY AND UPPER
DIVERGENT SUPPORT. OUR NORTHERN CWA WILL STILL BE UNDER THE GUN
FOR CONVECTION AND HEAVY RAINFALL THROUGH THE REMAINDER OF THE
NIGHT BUT POPS SHOULD DIMINISH QUICKLY FURTHER TO THE SOUTH AND
HAVE ADJUSTED REMAINDER OF OVERNIGHT PERIOD TO ACCOUNT FOR THIS.

ALL MODELS STILL BRING REMNANTS OF MCS THROUGH THE AREA TODAY WITH
ADDITIONAL DEVELOPMENT ALONG ANY REMNANT BOUNDARIES AND UPPER
LEVEL SHORTWAVE ENERGY. WILL BE GOING WITH 60 TO 70 POPS ACROSS
ALL BUT SOUTHEAST CWA TO ACCOUNT FOR THIS TODAY.

MAY SEE A LITTLE BREAK IN THE PRECIPITATION CHANCES WEDNESDAY
NIGHT BUT CANNOT RULE THEM OUT COMPLETELY...ESPECIALLY DURING THE
EVENING.

MAIN FRONTAL PASSAGE WILL NOT ARRIVE UNTIL THURSDAY/THURSDAY NIGHT
TIME FRAME ACROSS THE CWA. PRECIPITATION CHANCES WILL INCREASE
AGAIN WITH THE FRONTAL PASSAGE WITH MUCH COOLER/DRIER AIR MASS
MOVING IN BEHIND THE FRONT AND ENDING PRECIPITATION CHANCES FROM
NORTHWEST TO SOUTHEAST THURSDAY NIGHT. STRONG TO POSSIBLY SEVERE
STORMS MAY DEVELOP ALONG THE FRONT IF ENOUGH INSTABILITY CAN
DEVELOP DURING THE DAY.

DRY CONDITIONS EXPECTED THROUGH THE WEEKEND BEHIND THE FRONT AS
COOLER/DRIER AIR MASS MOVES INTO THE AREA.

.AVIATION...

FOR THE 01/0600Z KSGF/KJLN/KBBG TAFS...AN AREA OF WEAKENING
THUNDERSTORMS WILL SHIFT SOUTHEAST FROM THE THE KC METRO AREA
OVERNIGHT. ANOTHER SMALL CLUSTER OF THUNDERSTORMS OVER NE OK/SE KS
MAY ALSO TRY TO MOVE INTO THE KJLN AREA OVERNIGHT. WILL TRY TO
ESTIMATE THE ONSET TIME OF ANY PRECIP AS BEST I CAN...BUT BOTH THESE
STORM CLUSTERS WILL BE FIGHTING AN INCREASINGLY STABLE BOUNDARY
LAYER. BELIEVE SHRA/TSTM CHANCES WILL INCREASE DURING THE 08Z-11Z
TIME FRAME AT KSGF/KJLN. MAINLY MVFR CEILINGS WILL OCCUR WITH THE
PRECIP...BUT CAN'T RULE OUT BRIEF IFR VISIBILITY WITH HEAVIER
SHOWERS. WILL LIKELY STAY THE COURSE WITH GENERALLY MVFR CONDITIONS
WITH THE CONVECTION. AFTER 16Z...WILL GO PREDOMINANTLY VFR...BUT
THIS IS HIGHLY UNCERTAIN GIVEN WEAKENING CONVECTION OVER THE REGION
AND THE POTENTIAL FOR AFTERNOON REDEVELOPMENT WHERE SUFFICIENT SFC
HEATING OCCURS.  DSA
