AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO

/ISSUED 140 PM CDT SAT JUN 12 2010/

MAIN FORECAST FOCUS IN THIS FORECAST PACKAGE WILL DEAL WITH
THUNDERSTORM CHANCES THIS AFTERNOON INTO THE EARLY EVENING. THEN
ATTENTION TURNS TO CONTINUED THUNDERSTORM CHANCES AT TIMES SUNDAY
INTO THE MIDDLE OF THE UPCOMING WEEK.

CURRENTLY...A COMPLEX OF THUNDERSTORMS IS LOCATED ACROSS EASTERN
KANSAS TO THE NORTHEAST INTO ILLINOIS. AHEAD OF THIS ACTIVITY A
WARM AND HUMID AIRMASS IS IN PLACE AS TEMPERATURES ARE IN THE MID
TO UPPER 80S WITH DEWPOINTS AROUND 70 DEGREES. AS A RESULT AN
UNSTABLE AIRMASS HAS DEVELOPED ACROSS THE AREA. MLCAPE VALUES ARE
GENERALLY IN THE 2000 TO 3000 J/KG RANGE. TEMPERATURES HAVE OR ARE
REACHING CONVECTIVE TEMPERATURES...SO VERY LITTLE MLCIN IS IN
PLACE ACROSS THE AREA. EXPECTED SCATTERED SHOWERS AND
THUNDERSTORMS TO START DEVELOPING ACROSS THE AREA...ESPECIALLY
ALONG OUTFLOW BOUNDARIES FROM THE THUNDERSTORM ACTIVITY TO THE
NORTH.

THERE IS A LAYER OF DRY AIR IN THE MID LEVELS OF THE ATMOSPHERE
AND MID LEVEL LAPSE RATES ARE GETTING A LITTLE STEEPER ACROSS THE
AREA. THESE CONDITIONS WILL RESULT IN A SEVERE WEATHER RISK WITH
STRONG WINDS AND MARGINALLY SEVERE HAIL THE MAIN THREATS EXPECTED.
PRECIPITABLE WATER VALUES ARE QUITE HIGH ACROSS THE AREA AS VALUES
ARE GENERALLY IN THE 1.8 TO 2 INCH RANGE. THE MOISTURE CONDITIONS
AND THE POSSIBILITY FOR TRAINING STORMS WILL RESULT IN A LOCALIZED
FLASH FLOODING RISK THIS AFTERNOON AND EARLY EVENING. WITH THE
LOSS OF DAY TIME HEATING AND INSTABILITY...THE THUNDER ACTIVITY
SHOULD DISSIPATE DURING THE MID EVENING HOURS.

ANOTHER MCS IS EXPECTED TO DEVELOP ACROSS THE CENTRAL PLAINS
TONIGHT AND PUSH TO THE EAST OVERNIGHT INTO SUNDAY MORNING. WILL
HAVE TO WAIT TO SEE WHERE IT DEVELOPS TO REALLY GET A GOOD HANDLE ON
WHERE IT WILL MOVE. FEEL THE BETTER CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL REMAIN TO THE NORTH OF THE CWA. HAVE INCREASED
POPS TO THE CHANCE CATEGORY ACROSS THE NORTHWESTERN CWA AS THESE
AREAS HAVE THE BEST POTENTIAL TO SEE THIS ACTIVITY TONIGHT INTO
SUNDAY MORNING.

ANOTHER WARM AN HUMID DAY IS EXPECTED ON SUNDAY...AS HIGHS AGAIN
WARM AROUND THE 90 DEGREE MARK. A WARM AND UNSTABLE AIRMASS WILL
ONCE AGAIN DEVELOP ACROSS THE AREA ON SUNDAY AS A RESULT OF THE
WARM AND HUMID CONDITIONS. THESE CONDITIONS ALONG WITH OUTFLOW
BOUNDARIES FROM TONIGHTS EXPECTED MCS SHOULD RESULT IN
THUNDERSTORM CHANCES ACROSS THE AREA ON SUNDAY. GIVEN THE
INSTABILITY A FEW STRONG TO MARGINALLY SEVERE STORMS WILL BE
POSSIBLE.

AN UPPER LEVEL LOW WILL PUSH INTO THE NORTHERN PLAINS SUNDAY
NIGHT...WHICH WILL RESULT IN THE RIDGE FLATTENING AND A SURFACE
FRONT TO SLOWLY PUSH SOUTH. THE FRONT AND ASSOCIATED HEAVY
RAINFALL SHOULD REMAIN TO THE NORTH OF THE AREA SUNDAY NIGHT. THE
FRONT SHOULD SLIDE INTO THE AREA AND BE THE FOCUS FOR
THUNDERSTORMS ACROSS THE AREA ON MONDAY. A RISK FOR SEVERE WEATHER
WILL EXIST ON MONDAY AS AN UNSTABLE AIRMASS AND INCREASED WIND
SHEAR WILL BE IN PLACE ACROSS THE AREA.

THE FRONT IS EXPECTED TO STALL OVER THE AREA INTO THE MIDDLE OF
THE WEEK. SEASONABLE TEMPERATURES AND CHANCES FOR THUNDERSTORMS AT
TIMES CAN BE EXPECTED INTO WEDNESDAY. THE FRONT WILL PUSH NORTH OF
THE AREA LATE WEDNESDAY AS AN UPPER LEVEL RIDGE BUILDS INTO THE
AREA. WARM AND HUMID CONDITIONS CAN ONCE AGAIN BE EXPECTED DURING
THE END OF THE WORK WEEK.

ANY STORMS. MOST OF THIS ACTIVITY WILL DIMINISH BY EARLY THIS
