AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
600 PM MDT SAT SEP 12 2015

.SHORT TERM...(THIS EVENING THROUGH MONDAY NIGHT)
ISSUED AT 340 PM MDT SAT SEP 12 2015

FIRE WEATHER CONCERNS WILL CONTINUE TO BE THE FOCUS OVER THE NEXT
COUPLE DAYS IN AN OTHERWISE WARM AND MOSTLY DRY PATTERN ACROSS
THE CWA. CLEAR SKIES OVERNIGHT INTO SUNDAY AS AN UPPER RIDGE
PASSES ACROSS THE AREA WHILE DEAMPLIFYING. UPPER FLOW WILL TURN TO
WESTERLY DURING THE DAY SUNDAY WHILE LEE TROFFING DEVELOPS OVER
THE PLAINS. THIS WILL BRING SOME INCREASE IN WINDS MAINLY OVER SE
WY AND PRODUCE THE HIGHER CONCERNS FOR FIRE CONDITIONS. LITTLE
CHANGE OVERALL SUNDAY NIGHT INTO MONDAY EXCEPT FOR SOME INCREASE
IN MOISTURE MONDAY AS THE UPPER FLOW BACKS TO SWLY AHEAD OF AN
UPPER TROF THAT WILL DIG ALONG THE WEST COAST. MAYBE ENOUGH
MOISTURE WILL ADVECT INTO THE AREA TO ALLOW FOR A FEW SHOWERS AND
TSTMS LATE MONDAY MAINLY OVER THE HIGHER MTNS. OTHERWISE CONTINUED
QUITE WARM.

.LONG TERM...(TUESDAY THROUGH FRIDAY NIGHT)
ISSUED AT 340 PM MDT SAT SEP 12 2015

12Z MODELS CONTINUE TO SHOW THE UPPER LEVEL TROUGH SOLUTION
THROUGH MIDWEEK. AN INITIAL WAVE LOOKS TO ROUND THE BASE OF THE
TROUGH ACROSS THE PAC NW AND INTO SW CANADA ON TUESDAY...WITH THE
LEESIDE TROUGH DEEPENING AND SFC WINDS ACROSS THE CWA BECOMING
QUITE BREEZY AS A RESULT. A WEAKER SHORTWAVE...WHICH SORT OF LOOKS
LIKE A SOUTHERN EXTENSION TO THE MAIN WAVE UP NORTH...IS PROGGED
TO MOVE ACROSS THE ROCKIES AT THIS TIME AS WELL AND WILL CARRY
WITH IT SOME PACIFIC MOISTURE. THUS SHOULD SEE A FEW OROGRAPHIC
SHOWERS AND TSTMS THRU THE DAY. THINKING THAT ENOUGH DOWNSLOPE
DRYING AND SUBSIDENCE WILL KEEP THE PLAINS MOSTLY DRY...HOWEVER
CANNOT COMPLETELY RULE OUT A LIGHT SHOWER OR TWO. MODELS THEN SHOW
A SECOND AND DEEPER SHORTWAVE DIGGING INTO THE PAC NW TUESDAY
NIGHT- WEDNESDAY WITH INCREASING PVA AIDING IN THE DEVELOPMENT OF
MORE CONVECTION ACROSS THE CWA ON WEDNESDAY. WITH STRONGER ENERGY
EXPECTED TO BE OVERHEAD...KEPT CHANCE POPS IN THE MOUNTAINS WITH
SLIGHT CHANCE OVER MUCH OF THE PLAINS. AGAIN...BREEZY CONDITIONS
WILL BE IN PLACE WITH THE DEEPENING OF THE LEE TROUGH IN ADVANCE
OF THIS WAVE WHICH COULD PUT A DAMPER ON CONVECTION ACROSS THE
PLAINS. FINALLY...THE REMAINING PIECE OF THE TROUGH WILL MOVE EAST
ACROSS THE ROCKIES THURSDAY AND THURSDAY NIGHT AND WILL DRAG A
COLD FRONT ACROSS THE CWA THROUGH THIS TIME. MODELS BOTH PAINT
SOME QPF OVER THE MOUNTAINS THEN EASTERN PLAINS THURSDAY AFTERNOON
THRU EVENING...SO ADDED IN LOW END POPS FOR THIS SCENARIO. FRIDAY
AND FRIDAY NIGHT LOOK DRY WITH LESS WIND OVERALL. TEMPERATURES
THROUGH THE WEEK WILL PROGRESSIVELY COOL WITH EACH PASSING WAVE.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING)
ISSUED AT 544 PM MDT SAT SEP 12 2015

RETURNING BY THE AFTERNOON IN SOUTHEAST WYOMING.

CONCERNS THAT WIND MAY NOT GET CRITICALLY HIGH OVER THE FAR EAST
PARTS. CRITICAL OR NEAR CRITICAL CONDITIONS POSSIBLE ONCE AGAIN
OVER WESTERN DISTRICTS MONDAY AFTERNOON WITH ADDITIONAL AT LEAST
ELEVATED CONDITIONS POSSIBLE THROUGH MIDWEEK.
