Area forecast discussion, Jun 2, 6:23 AM CDT, 5 hours 47 minutes before

AREA FORECAST DISCUSSION...AVIATION UPDATE.
NATIONAL WEATHER SERVICE SPRINGFIELD MO
623 AM CDT TUE JUN 2 2009

.DISCUSSION...

MAIN FOCUS WITH THIS FORECAST PACKAGE WILL BE CONVECTION AND
SEVERE CHANCES TODAY THROUGH WEDNESDAY.

CONVECTION CONTINUES TO DEVELOP OVER NORTHEAST KANSAS EARLY THIS
MORNING ALONG AND NORTH OF THE SURFACE FRONTAL BOUNDARY. LOW LEVEL
JET CONTINUES TO FEED DECENT MOISTURE INTO THE AREA FROM THE
SOUTH. OUTFLOW FROM THIS THUNDERSTORM COMPLEX PUSHING SOUTH INTO
EAST CENTRAL KANSAS AND WEST CENTRAL MISSOURI.

AN UPPER SHORTWAVE DROPPING SOUTHEAST ACROSS THE UPPER MS VALLEY
TODAY AND TONIGHT WILL ALLOW STATIONARY BOUNDARY TO THE NORTH TO
BEGIN ADVANCING SOUTH AND SHOULD BE BISECTING THE WESTERN/NORTHERN
CWA BY EARLY EVENING. STRONG TO SEVERE STORMS WILL BE POSSIBLE
LATE AFTERNOON AND EVENING ALONG THESE BOUNDARIES AS INCREASING
LOW LEVEL MOISTURE AND AFTERNOON HEATING AHEAD OF FRONT ALLOW
CAPES TO INCREASE INTO THE 1500-2500 J/KG RANGE. BULK SHEAR NOT
ALL THAT IMPRESSIVE FOR THE CWA AND THINKING IS MAIN SEVERE
WEATHER HAZARDS WOULD BE WITH DAMAGING WIND AND HAIL.

AS LOW LEVEL MOISTURE INCREASES OVER THE CWA TODAY...PW VALUES
WILL INCREASE INTO THE 1.5-1.6 IN. RANGE. SHORTWAVE ENERGY WILL BE
MOVING IN FROM THE WEST THIS EVENING AND TONIGHT WITH LOW LEVEL
JET FEEDING INTO THE AREA LATE TONIGHT. AREA OVER SOUTHEAST KANSAS
AND THE SOUTHWEST CORNER OF MISSOURI INTO CENTRAL MISSOURI LOOKS
LIKE THE REGION WITH THE HIGHEST POTENTIAL FOR HEAVY RAIN TONIGHT
INTO WEDNESDAY AND AM PONDERING A FLASH FLOOD WATCH.

PRECIPITATION CHANCES WILL LINGER INTO WEDNESDAY NIGHT OVER SOUTH
CENTRAL MISSOURI WITH SHORTWAVE ENERGY CONTINUING TO PUSH ACROSS
THE AREA AND 850 FRONT SLOW TO PUSH THROUGH. CLOUDS/PRECIPITATION
AND COOLER AIR MASS BEHIND FRONT WILL KEEP WEDNESDAYS HIGHS FROM
THE UPPER 60S TO LOW 70S IN MOST LOCATIONS IN THE CWA.

DRY AND COOLER THAN NORMAL TEMPERATURES ARE EXPECTED ON THURSDAY
AS SURFACE RIDGE BUILDS INTO THE AREA.

NOT MUCH CHANGE TO DAYS 4 AND 5 BUT COULD SEE SOME PRECIPITATION
FRIDAY NIGHT INTO SATURDAY AS GFS SHOWS UPPER SHORTWAVE ENERGY
MOVING ACROSS SOUTHERN KANSAS INTO MISSOURI.

.AVIATION...

PILOTS FLYING IN AND OUT OF SOUTHERN MISSOURI CAN EXPECT VFR
CONDITIONS UNTIL THUNDERSTORMS DEVELOP SOMETIME LATE THIS AFTERNOON
AND THROUGH TONIGHT.

A COLD FRONT WILL SLOWLY SAG INTO THE REGION...MEANWHILE...AN UPPER
LEVEL DISTURBANCE WILL HELP TRIGGER THUNDERSTORMS ALONG THIS FRONT.
ANY STORMS THAT DIRECTLY IMPACT AN AIRPORT WILL CAUSE FLIGHT
CONDITIONS TO DETERIORATE.  STORMS WILL BE POSSIBLE THROUGH THE END
OF THE 24 HOUR TAF PERIOD.
