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.
