.DISCUSSION...
330 PM MDT FRI JUN 25 2010

THE UPPER RIDGE IN PLACE TODAY IS FLATTENED BY A A SHORT WAVE
TROUGH LIFTING EAST OF THE ROCKIES ON SATURDAY. DAYTIME
TEMPERATURES ON SATURDAY WILL BE MODERATED SOMEWHAT FROM THE HOT
READINGS TODAY DUE TO THE ADDITIONAL CLOUD COVER EXPECTED WITH THE
TROUGH.

UPPER LEVEL FEATURES ARE COINCIDENT IN THE SHORT TERM BUT THE TIMING
OF THE SURFACE FRONT ACROSS THE REGION BY LATE SATURDAY DIFFERS
ACCORDING TO MODEL CHOICE. HAVE CONTINUED TO LEAN TOWARDS A SLOWER
SOLUTION...WHICH APPEARS TO BE CLOSER TO THE NAM SOLUTION. THE NAM
IS BREAKING OUT PRECIPITATION ALONG OR SLIGHTLY AHEAD OF THE
SURFACE FRONT WHILE THE GFS IS KEEPING PRECIPITATION CONFINED
MAINLY TO THE REGION BEHIND THE FRONT. WITH THE LIFT PROVIDED BY
THE FRONT PROVIDING A FOCUS FOR THUNDERSTORM DEVELOPMENT ON
SATURDAY AND SATURDAY EVENING...THAT'S ANOTHER REASON TO FAVOR THE NAM
SOLUTION OVER THE GFS. HAVE GONE WITH SCATTERED THUNDERSTORMS
MAINLY NORTH OF INTERSTATE 70 DURING THE LATE SATURDAY AFTERNOON
AND EVENING WITH LINGERING STORMS EXPECTED TO LIFT OUT OF THE
FORECAST AREA OVERNIGHT.

EXPECT ADDITIONAL CHANCES OF THUNDERSTORMS MAIN IN THE ACROSS THE
WESTERN PORTION OF THE FORECAST AREA SUNDAY EVENING AND MONDAY
EVENING AS THE WESTERLY FLOW OVER THE ROCKIES TRANSITIONS TO A
MORE NORTHWESTERLY DIRECTION.

THE UPPER RIDGE AMPLIFIES SHARPLY OVER THE HIGH PLAINS ON TUESDAY
AND MOVES OVER THE CENTRAL U.S. ON WEDNESDAY. EXPECT HIGH
TEMPERATURES WELL INTO THE 90S WITH MAINLY DRY CONDITIONS AS A RESULT.

.AVIATION...
550 PM MDT FRI JUN 25 2010

FOR THE 00Z TAF...VFR CONDITIONS EXPECTED AT BOTH KGLD AND KMCK
THROUGH THE EFFECTIVE PERIOD. CONVECTION ONGOING JUST EAST OF KGLD
CURRENTLY WILL CONTINUE TO PROPAGATE EASTWARD AWAY FROM THE
TERMINAL BUT MAINTAINED CB MENTION THROUGH 03Z. BEYOND
THAT...EXPECT GENERALLY SKC WITH A FEW MID-LEVEL CLOUDS. FOR
KMCK...CURRENT INDICATIONS ARE THAT CB/CONVECTIVE CHANCES THIS
EVENING ARE TOO MINIMAL TO INCLUDE IN THIS TAF ISSUANCE. DO
ANTICIPATE THE POTENTIAL FOR CONVECTION LATE TOMORROW AFTERNOON
FOR BOTH TERMINALS. TEMPORAL/SPATIAL DETAILS ARE TOO VAGUE AT THIS
POINT TO WARRANT ANYTHING MORE THAN CB MENTION.
