AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
237 PM CDT SUN JUN 29 1997

POPS AND TEMPS ARE CONCERNS TODAY

WEATHER BECOMING MORE SUMMERLIKE BY THE MINUTE ACROSS THE OZARKS:
SCATTERED THUNDERSTORM DEVELOPMENT HAS BEEN CONFINED TO THE SOUTHERN
THIRD OF THE FORECAST AREA...IN THE DEEPER MOISTURE AND CLOSER TO THE
MIDDLE LEVEL ENERGY. KANSAS/NEBRASKA THUNDERSTORM COMPLEX TRIED TO
FIZZLE OUT THIS MORNING BUT SHOULD LIMP INTO THE NORTHWEST CORNER OF
THE FORECAST AREA. CORRESPONDING WAVE SHOWS UP WELL AT H5 AND H7 ON THE
PROFILER NETWORK. WITH PRECIPITABLE WATER AROUND 1.5" AND WEAK MID
LEVEL WINDS...HEAVY RAIN THE MAIN THREAT AGAIN TODAY.

MODELS IN PRETTY GOOD AGREEMENT FOR THIS FORECAST PACKAGE: MCS EXPECTED
OVER KANSAS/NEBRASKA AGAIN TONIGHT...WITH THIS SYSTEM MOVING INTO
SOUTHEAST KANSAS/WESTERN MISSOURI AFTER MIDNIGHT. IF COMPLEX WEAKENS
MONDAY MORNING...CONVECTION SHOULD FIRE ALONG REMNANTS MONDAY AFTERNOON.
H5 RIDGE THEN BUILDS IN MONDAY NIGHT...LOWERING POPS TO NEAR ZERO AND
WARMING TEMPERATURES UP TO AT OR ABOVE SEASONABLE LEVELS.

TOUGH EXTENDED FORECAST: H5 RIDGE WILL FLATTEN AND A COLD FRONT WILL
TRY TO PUSH INTO THE MISSOURI OZARKS WEDNESDAY. PROBLEM IS DETERMINING
WHERE THE FRONT WILL HANG UP: COULD SEE RANGE FROM MID 80S TO MID 90S
ACROSS THE FORECAST AREA THURSDAY.

FAN GUIDANCE LOOKS TOO COOL...SO WILL LEAN IN THE DIRECTION OF FWC. FAN
ALSO LOOKS LIKE IT HOLDS ON TO POPS TOO LONG.

FIRST PERIOD THOUGHTS AND IDEAS:
SGF/AIZ: WIDELY SCATTERED SHOWERS/THUNDERSTORMS THIS EVENING...GOOD
CHANCE AFTER MIDNIGHT. LOW UPPER 60S.
JLN: WIDELY SCATTERED SHOWERS/THUNDERSTORMS THIS EVENING...LIKELY AFTER
MIDNIGHT. LOW NEAR 70.
UNO: WIDELY SCrATTERED SHOWERS/THUNDERSTORMS THIS EVENING...OTHERWISE
PARTLY CLOUDY. LOW 65 TO 70.

...SCATTERED THUNDERSTORMS POSSIBLE THIS AFTERNOON AND EARLY EVENING...
...BETTER CHANCE OF RAIN OVERNIGHT AND EARLY MONDAY MORNING...

A MOIST AND UNSTABLE ATMOSPHERE REMAINED OVER THE MISSOURI OZARKS AND
SOUTHEAST KANSAS THIS AFTERNOON. NUMEROUS OUTFLOW BOUNDARIES...THE
REMNANTS FROM DECAYING THUNDERSTORMS...WERE ALSO PRESENT.  SCATTERED
THUNDERSTORMS WILL CONTINUE TO DEVELOP THIS AFTERNOON ALONG THESE
BOUNDARIES.

THE AREA SOUTH OF A NEOSHO TO SPRINGFIELD AND SALEM LINE APPEARS TO
HAVE THE GREATEST CHANCE OF THESE RANDOM SHOWERS AND THUNDERSTORMS
THROUGH SUNSET. ISOLATED SEVERE THUNDERSTORMS...PRODUCING HAIL UP TO
ONE INCH IN DIAMETER AND 60 MPH WINDS...WILL BE POSSIBLE BUT HEAVY
RAINFALL WILL BE THE MAIN THREAT. THE STORMS ARE EXPECTED TO DISSIPATE
SHORTLY AFTER SUNSET.

ALSO...AN AREA OF SHOWERS AND THUNDERSTORMS OVER CENTRAL KANSAS MAY
PERSIST LONG ENOUGH TO AFFECT EAST CENTRAL KANSAS AND WEST CENTRAL
MISSOURI LATER THIS AFTERNOON. AGAIN...HEAVY RAIN WOULD BE THE MAIN
THREAT FROM THESE STORMS SHOULD THEY REACH MISSOURI. A FEW STORMS COULD
PRODUCE HAIL AND 50 TO 60 MPH WINDS.

A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS WILL OCCUR AFTER MIDNIGHT
AS A COMPLEX OF THUNDERSTORMS EXPECTED TO FORM OVER NEBRASKA AND KANSAS
MOVES SOUTHEAST.  THE AREA WEST OF A WARSAW TO SPRINGFIELD AND BRANSON
LINE APPEARS TO HAVE THE BEST CHANCE OF RAIN FROM THIS OVERNIGHT
SYSTEM. ALTHOUGH HEAVY RAINFALL WILL CONTINUE TO BE THE MAIN
THREAT...THERE IS THE POTENTIAL FOR DAMAGING WINDS FROM THE COMPLEX.

SPOTTER ACTIVATION MAY BE REQUIRED AFTER MIDNIGHT IN SOUTHEAST KANSAS
AND WESTERN MISSOURI.
