NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
100 PM CDT WED JUL 25 2001

FORECAST: SCATTERED SHOWERS WILL REMAIN POSSIBLE THIS AFTERNOON AND

DEVELOPMENT THIS EVENING.

OUTLOOK:  A BREAK FROM THE STORMS WILL OCCUR ON THURSDAY...WITH
SLIGHTLY COOLER CONDITIONS.  STORMS WILL BE POSSIBLE AGAIN ON
FRIDAY...FIRST IN EASTERN KANSAS AND WESTERN MISSOURI...THEN ACROSS
MUCH OF EASTERN KANSAS AND MISSOURI FRIDAY NIGHT AND INTO SATURDAY.
AFTER THAT...DRY WEATHER SHOULD RETURN FOR THE FIRST OF NEXT
WEEK...WITH TEMPERATURES EXPECTED TO CLIMB BACK TOWARD THE 90 DEGREE
MARK BY MONDAY AND TUESDAY.
