AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
224 PM CDT FRI JUN 19 1998

MAIN FORECAST CONCERN IS PRECIPITATION CHANCES THROUGH 3RD PERIOD.
VISIBLE SATELLITE IMAGERY AND SURFACE ANALYSIS SHOWING BOUNDARY OVER
SOUTHWEST MISSOURI AND SOUTHERN KANSAS MAKING ITS MOVE NORTHWARD.
HAVE SOME CONCERN REGARDING CONVECTIVE DEVELOPMENT WITH SURFACE
HEATING ALONG BOUNDARY...AS SATELLITE IMAGERY ALREADY SHOWING SOME
CU FORMING ALONG AND BEHIND FRONT. DESPITE STRONG WARM AIR AND
THETA-E ADVECTION TONIGHT...LACK OF ANY SYNOPTIC SCALE UPPER LEVEL
SUPPORT SHOULD LIMIT THUNDERSTORM DEVELOPMENT. WILL LEAVE OUT OF
FORECAST AT THIS TIME...HOWEVER THIS WILL DEFINATELY HAVE TO
MONITORED.

ATTENTION THEN TURNS TO BOUNDARY AND SHORTWAVE APPROACHING FROM WEST
AND NORTHWEST. GOING FORECAST HAS THIS COVERED WELL...SO WILL NOT
MAKE ANY CHANGES TO POPS. WARM MID-LEVEL TEMPERATURES MAY INITIALLY
BE A PROBLEM FOR CONVECTIVE DEVELOPMENT...HOWEVER BOTH ETA AND NGM
HINT AT H7 THERMAL TROUGH ASSOCIATED WITH SHORTWAVE WHICH MAY ALLOW
FOR SOME DEVELOPMENT MAINLY AFTER 00Z SUNDAY. AGREE WITH NCEP
DISCUSSIONS...WHICH STALLS BOUNDARY OVER AREA AND ROTATES SERIES OF
WEAK SHORTWAVES OVER IT INTO EXTENDED PERIOD. NOCTURNAL MCS
DEVELOPMENT APPEARS POSSIBLE...AND AS A RESULT WILL INSERT CHANCE
FOR TSRA FOR MONDAY AND TUESDAY.

FWC/FAN GUIDANCE TEMPERATURES APPEAR TO BE IN BALLPARK...SO WILL NOT
STRAY FAR.

MO...NONE.
