LONG TERM: UPPER LEVEL RIDGE HAD BEEN PROGGED TO MOVE OVER THE
COUNTY WARNING AREA FRIDAY AND SATURDAY...BUT LATEST RUNS INDICATE
THAT AN ACTIVE CONVECTIVE PATTERN WILL CONTINUE. THIS SEEMS
REASONABLE AS WEAK SHORT WAVES PASS OVER THE HIGH PLAINS FROM THE
PACIFIC NORTHWEST. THE AIR MASS OVER THE AREA WILL CONTINUE TO BE
RELATIVELY MOIST AND UNSTABLE. WEAK SURFACE BOUNDARY WILL EXTEND
FROM EASTERN WYOMING TO SOUTHEASTERN COLORADO BY FRIDAY AFTERNOON
WHICH MAY SERVE AS A FOCUSING MECHANISM FOR CONVECTION. NGM GRIDDED
DATA SHOWS SOME ENHANCED LIFT BY FRIDAY AFTERNOON. SO...WILL KEEP
MENTION OF THUNDERSTORMS GOING THROUGH FRIDAY EVENING. WARMER AIR
WILL MOVE OVER THE AREA SATURDAY...AND THE AIR MASS MAY BECOME
CAPPED AT THAT POINT. SHOULD ALSO HAVE SOME WEAK DOWNSLOPE WINDS
NEAR THE COLORADO/KANSAS BORDER. WILL KEEP AFTERNOON CONV0ECTION
MENTIONED IN THE EASTERN PARTS OF AREA...BUT WILL GO DRY ELSEWHERE.
