AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
627 PM CDT MON JUN 8 2009

...UPDATE TO AVIATION...

.DISCUSSION...

MAIN FOCUS FOR THIS FORECAST WILL BE WITH CONVECTIVE PRECIPITATION
CHANCES.

COLD FRONT AS OF 19Z WAS BISECTING THE CWA FROM JUST NORTH OF JLN
TO JUST NORTH OF SGF TO VIH. FAIRLY DECENT MOISTURE CONVERGENCE
AHEAD OF THE FRONT. CLOUDS FROM DEPARTING MCS THIS MORNING ERODED
BY LATE MORNING AND ALLOWED TEMPERATURES TO REACH THE LOW TO MID
80S. SURFACE BASED CAPES HAVE CLIMBED INTO THE 3500 TO 4000 J/KG
RANGE AHEAD OF THE FRONT AND WOULD EXPECT STORMS TO BEGIN
INITIATING OVER THE NEXT COUPLE OF HOURS. SOME OF THE STORMS COULD
BECOME SEVERE GIVEN THE STRONG INSTABILITY AND STEEP MID LEVEL
LAPSE RATES. LARGE HAIL AND DAMAGING WIND WOULD BE THE MAIN SEVERE
WEATHER HAZARDS EXPECTED.

FRONT WILL CONTINUE TO SLIDE SOUTHEAST TONIGHT AND STALL ALONG THE
MISSOURI ARKANSAS BORDER. LOW LEVEL JET WILL AGAIN REDEVELOP OUT
IN THE PLAINS OVERNIGHT AND SHOULD SEE ADDITIONAL CONVECTION FIRE
UP OUT IN WESTERN/CENTRAL KANSAS. THIS ACTIVITY COULD MAKE IT INTO
WESTERN CWA BY TUESDAY MORNING. FRONT WILL MOVE BACK THROUGH THE
AREA AS A WARM FRONT ON TUESDAY WITH CWA MOVING BACK INTO THE WARM
SECTOR. MAIN BULK OF PRECIPITATION WILL BE ALONG AND NORTH OF THE
FRONT OVER SOUTHERN IOWA AND NORTHERN MISSOURI THROUGH TUESDAY
NIGHT BUT CERTAINLY CAN NOT RULE OUT PRECIPITATION...ESPECIALLY
EARLY IN THE DAY WITH REMNANT MCS ACTIVITY IN THE WEST. REMNANT
BOUNDARIES FROM THAT COULD SPARK SOME AFTERNOON CONVECTION WITHIN
THE WARM SECTOR.

BY WEDNESDAY...FRONT WILL BEGIN TO MEANDER AGAIN TO THE SOUTH AND WILL
LIKELY SEE MORE THUNDERSTORM DEVELOPMENT ALONG THE FRONT OVER OUR
CWA BOTH WEDNESDAY AND WEDNESDAY NIGHT.

FOR THE EXTENDED PERIOD (THU THROUGH MON)...

OVERALL UPPER PATTERN NOT EXPECTED TO CHANGE TOO MUCH DURING THE
EXTENDED PERIOD WITH BROAD SOUTHWEST TO NORTHEAST FLOW CONTINUING.
SEVERAL SHORTWAVES WILL PUSH THROUGH FROM THE SOUTHWEST WHILE A
FRONT WILL CONTINUE TO MEANDER AROUND THE FORECAST AREA.  THE RESULT
WILL BE ALMOST THUNDERSTORM CHANCES EACH PERIOD.  HAVE TRIED TO TIME
THE HIGHER POPS WITH THE MAIN SHORTWAVES MAINLY SATURDAY INTO
SATURDAY NIGHT.

.AVIATION...

FOR THE 00Z TAFS...A COLD FRONT HAS JUST PUSHED SOUTH OF THE
SPRINGFIELD AREA WITH SHOWERS AND THUNDERSTORMS DEVELOPING TO THE
SOUTH AND EAST OF THE FRONT. EXPECT THESE STORMS TO STAY WELL
SOUTH AND EAST OF BOTH AIRFIELDS AND DECREASE IN COVERAGE AFTER
SUNSET. FRONT WILL SURGE NORTH AGAIN TUESDAY FOR ANOTHER ROUND OF
SHOWERS AND THUNDERSTORMS. CONFIDENCE IS NOT HIGH ON WHERE THIS
ACTIVITY WILL TAKE PLACE...SO WILL KEEP MENTION OF TSTMS OUT OF
TAFS UNTIL WE GET A LITTLE CLOSER.
