AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
940 PM MDT MON JUN 24 2013

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 301 PM MDT MON JUN 24 2013

SHOWERS AND THUNDERSTORMS WERE OVER THE NORTH THIRD OF THE CWA
EARLY THIS AFTERNOON AFTER FORMING ON THE NORTHERN LARAMIE RANGE.
AS THE ACTIVITY MOVES TO THE NORTHEAST IT WILL MOVES INTO A
BETTER ENVIRONMENT FOR STRONGER STORMS OVER THE NORTHEAST CORNER
OF THE CWA. FURTHER SOUTH AND WEST...MIXING HAS DRIED THE
BOUNDARY LAYER AND SHOULD LIMIT ANY STORM DEVELOPMENT. EARLY THIS
AFTERNOON A WARM FRONT WAS OVER THE NORTH EAST THIRD OF THE CWA.
THE ACTIVITY WILL BE AHEAD OF A SHORTWAVE TROUGH CURRENTLY OVER
EASTERN WYOMING. THAT FEATURE WILL BE EAST OF THE CWA BY LATE
EVENING. A COLD FRONT WILL THEN MOVE ACROSS THE REGION TONIGHT.

THE DRY AIR WILL SPREAD OVER THE ENTIRE CWA BEHIND THE FRONT
TONIGHT AND THEN PERSIST THROUGH TUESDAY. HOWEVER...ANOTHER
SHORTWAVE TROUGH OVER THE GREAT BASIN EARLY THIS AFTERNOON WILL
MOVE OVER THE CWA TONIGHT. SOME SHOWERS ARE ASSOCIATED OVER IDAHO
AND ALONG THE UTAH AND NEVADA BORDER CURRENTLY. AFTER A BRIEF BREAK
IN THE CLOUDS...MID AND HIGH LEVEL CLOUDS WILL INCREASE AS THE
FEATURE APPROACHES. SOME MODELS EVEN DEVELOP QPF OVER THE
PANHANDLE LATER TONIGHT. THAT WILL NEED TO BE WATCHED BUT WILL
LEAVE ONLY LOW POPS IN THAT AREA FOR LATER TONIGHT.

THE REST OF THE FORECAST WILL BE VERY WARM AND DRY FOR THE CWA AS
HEIGHTS ALOFT BUILD OVER THE ROCKIES. BY 00Z THURSDAY...A BROAD
RIDGE ALOFT WILL BE OVER THE CWA. TEMPERATURES WILL BE SLIGHTLY
COOLER ON TUESDAY BEHIND THE FRONT AND THEN REBOUND FOR WEDNESDAY.
THE TRANSITION TO MORE FIRE WEATHER CONCERNS CONTINUES FOR THE
ENTIRE CWA ON TUESDAY AND WEDNESDAY. GUSTY WINDS WILL CONTINUE
EARLY THIS EVENING OVER THE CWA AND THEN PICK BACK UP AGAIN LATER
TONIGHT WITH THE FRONTAL PASSAGE. ON TUESDAY...WEST TO NORTHWEST
WINDS WILL GUST AS 40 MPH OVER MUCH OF THE CWA. SOME MODELS DEVELOP
SOME QPF CENTERED OVER THE SOUTHERN LARAMIE RANGE WEDNESDAY
AFTERNOON. AT THIS TIME...MOISTURE APPEARS THAT IT WILL BE TOO
LIMITED FOR MUCH IN THE WAY OF SHOWERS AND THUNDERSTORMS FOR THAT
PERIOD.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 301 PM MDT MON JUN 24 2013

THE LARGE RIDGE ALOFT WILL REMAIN OVER THE ROCKIES THROUGH EARLY
NEXT WEEK. TEMPERATURES WILL BE ABOVE NORMAL DURING THAT TIME. THEY
WILL BE MODERATED BY AN INCREASE IN MID AND UPPER LEVEL MOISTURE
STARTING AS EARLY AS FRIDAY AS WELL AS LIGHT EASTERLY BOUNDARY
LAYER WINDS EAST OF THE LARAMIE RANGE. WILL CONTINUE THE LOW POPS
FOR THE WEEKEND AND EARLY NEXT WEEK DUE TO THE INCREASE IN
MOISTURE AND SURFACE CONVERGENCE.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY EVENING)
ISSUED AT 940 PM MDT MON JUN 24 2013

VFR EXPECTED OVER ALL TERMINALS THROUGH THE PERIOD WITH HIGH CLOUDS

PASS ACROSS THE AREA OVERNIGHT WITH GUSTY WESTERLY SFC WINDS

.FIRE WEATHER...
ISSUED AT 301 PM MDT MON JUN 24 2013

VERY WARM AND DRY WEATHER WILL CONTINUE OVER THE CWA THROUGH THE
WEEKEND AS HIGH PRESSURE ALOFT WILL BE CENTERED OVER THE ROCKIES.
SOME LATE DAY SHOWERS AND STORMS WILL AFFECT THE REGION THIS
WEEKEND AND EARLY NEXT WEEK AS MID AND UPPER LEVEL MOISTURE
INCREASES. THE ADDITIONAL CLOUD COVER WILL AID IN MODERATING
TEMPERATURES DURING THAT TIME. WESTERLY SURFACE WINDS WILL BE
GUSTY THROUGH THE EARLY EVENING AND THEN AGAIN LATER TONIGHT.
A COLD FRONT WILL MOVE ACROSS THE CWA TONIGHT AND WILL CREATE
WESTERLY SURFACE WINDS GUSTING AS HIGH AS 40 MPH FOR TUESDAY.

CRITICAL FIRE WEATHER CONDITIONS CAN BE EXPECTED MAINLY ON
TUESDAY OVER PARTS OF SOUTHEAST WYOMING. HOWEVER...FUELS IN MANY
AREAS ARE STILL SLOWLY DRYING AND NOT QUITE READY TO SUPPORT FIRE
