AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PLEASANT HILL/KANSAS CITY MO
238 PM CDT SAT JUN 28 1997

FORECAST CHALLENGES WILL BE CHANCES OF PRECIPITATION THROUGH
FORECAST PERIOD ALONG WITH TEMPERATURES. AFTERNOON HEATING COMBINED
WITH THE PRESENCE OF WEAK BOUNDARY THROUGH SOUTHERN AND WESTERN
PORTIONS OF THE FORECAST AREA SHOULD ALLOW SCATTERED/ISOLATED
CONVECTION TO FIRE INTO THIS EVENING. ACTIVITY SHOULD DIE DOWN
AFTER SUNSET...HOWEVER MODELS FORECAST H7 WAVE TO PUSH INTO
FORECAST AREA OVERNIGHT. BOTH PROFILERS AND 12Z UPPER-AIR ANALYSIS
HAVE SHOWN THIS FEATURE NICELY. ISOLATED/SCATTERED CONVECTION HAS
FIRED OVERNIGHT THE LAST COUPLE OF NIGHTS ACROSS CWA AND SEE NO
REASON TO AGAINST PERSISTANCE. WEAK MID-LEVEL FLOW WILL MEAN VERY
SLOW MOVING STORMS WITH THREAT FOR SOME LOCALLY HEAVY RAINFALL.

AGREE WITH NCEP DISCUSSIONS REGARDING STRENGTH OF NORTHERN PLAINS
SYSTEM AND PERSISTANCE OF EAST-WEST BOUNDARY JUST TO THE SOUTH OF
THE AREA THROUGH FORECAST PERIOD. TOMORROW AS SURFACE BOUNDARY AND
WEAK H7/H5 WAVE REMAIN IN THE VICINITY OF FORECAST AREA...FEEL THAT
ISOLATED CONVECTION STILL A POSSIBILITY. BETTER CHANCES FOR
PRECIPITATION ENTER INTO THE PICTURE ON SUNDAY NIGHT AND MONDAY AS
SIGNIFICANT LLJ DEVELOPS OUT OVER CENTRAL PLAINS AND MODELS HINT AT
POSSIBLE MCS.

BOTH FWC/FAN GUIDANCE NUMBERS APPEAR TO IN BALLPARK...WITH THE
EXCEPTION OF HIGHS ON MONDAY WHEN A COMPROMISE OF THE TWO WILL BE
USED.

.EAX...NONE.
