Area forecast discussion, May 23, 2:38 PM CDT, 6 hours 38 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
238 PM CDT TUE MAY 23 2000

FORECAST CHALLENGE WILL BE CONVECTIVE POTENTIAL TONIGHT...AND THEN
THURSDAY/FRIDAY TIMEFRAME. TEMPERATURES WILL ALSO BE OF SOME
CONCERN. WEAK SURFACE BOUNDARY HAS PRETTY MUCH SLIPPED TO THE SOUTH
OF CWA...ALLOWING DRIER AIR TO FILTER INTO THE NORTHWEST CORNER OF
MISSOURI. 18Z SURFACE ANALYSIS SHOWS BEST MOIST AXIS SHIFTED INTO
SOUTHEAST MISSOURI...WHICH COINCIDES WITH MSAS INSTABILITY AXIS
SPREAD ACROSS SOUTHERN MISSOURI INTO SOUTHEAST KANSAS. WITH ALL THIS
SAID...FEEL THAT BEST THREAT FOR CONVECTION WILL BE TO THE SOUTH OF
CWA. WILL MAINTAIN SMALL CHANCE POPS IN FAR SOUTHERN COUNTIES THIS
EVENING.

NEXT SURFACE BOUNDARY...CURRENTLY OVER THE DAKOTAS...IS ALSO OF SOME
CONCERN FOR LATE TONIGHT. MODELS INDICATE SOME LOW-LEVEL MOISTURE
RETURN AHEAD OF THIS FRONT LATE TONIGHT/TOMORROW MORNING...HOWEVER
BELIEVE THAT DIURNAL TIMING OF FRONT...AND ON GOING ACTIVITY TO THE
SOUTH OF THE AREA...SHOULD PRECLUDE ANY WIDESPREAD SHOWER AND
THUNDERSTORM ACTIVITY WITH THIS FEATURE. AT THIS TIME...AM NOT
PLANNING ON CARRYING POPS LATE TONIGHT OR TOMORROW MORNING.

MODELS INDICATE THAT BOUNDARY WILL SAG INTO NORTHERN OKLAHOMA AND
NORTHERN ARKANSAS TOMORROW...ALLOWING FOR SURFACE DEWPOINTS IN THE
40S TO FILTER INTO FORECAST AREA. IT IS NOT UNTIL LATE THURSDAY
AFTERNOON/THURSDAY NIGHT THAT THIS MODEL RETURNS THE BOUNDARY NORTH
AS A WARM FRONT. IN ADDITION...MODERATE H8 LLJ INDICATED BY ETA/AVN
THURSDAY NIGHT OVERRIDDING THIS BOUNDARY...WHICH SHOULD CREATE AN AREA
OF LOW-LEVEL WAA. ALSO UPPER JET MAX EJECTING OUT OF DESERT
SOUTHWEST SHOULD PROVIDE SOME UPPER-LEVEL DIFFLUENCE TO COINCIDE
WITH LOWER-LEVEL SUPPORT. WILL NOT GET CARRIED AWAY WITH POPS AT
THIS POINT...HOWEVER IT DOES LOOK LIKE A DECENT SHOT A GETTING AT
LEAST SOME PRECIPITATION. H7 TEMPERATURES WARM QUICKLY INTO THE +10
TO +12 RANGE DURING THE DAY ON FRIDAY...HOWEVER MRF...AND TO A
LESSER DEGREE THE CANADIAN...SHOWS FRONTAL BOUNDARY PUSHING THROUGH
LATE FRIDAY INTO SATURDAY MORNING. AFTER THIS...EXTENDED LOOKS DRY
FOR THE REMAINDER OF THE HOLIDAY WEEKEND.

NEW MODEL GUIDANCE CAME IN A BIT WARMER FOR TONIGHT AND TOMORROW
THAN PREVIOUS RUNS...SO WILL ADJUST GOING FORECAST UPWARD SOME FOR
THOSE PERIODS. OTHERWISE...AM EXPECTING TO GENERALLY GO WITH A BLEND
OF FWC AND FAN GUIDANCE THROUGH THE FORECAST CYCLE.

COORD WITH TOP AND STL.

.EAX...NONE.
