AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
345 AM MDT THU AUG 24 2006

.SHORT TERM...THE SHORTWAVE TROUGH WAS LOCATED FROM EASTERN MONTANA
TO WEST CENTRAL WYOMING EARLY THIS MORNING.  THE NORTHERN PORTION OF
THE FEATURE WAS MOVING FASTER THAN THE SOUTHERN PORTION...RESULTING
IN CLOUDS PARRELLING THE FLOW ALOFT BACK INTO NORTHERN UTAH.  AS OF
09Z SOME SHOWERS WERE STILL LINGERING FROM KSAA TO KLSK.  THE SHOWERS
WERE ASSOCIATED WITH THE ASCENT FROM THE 250 MB JET SEGMENT AHEAD OF
THE SHORTWAVE TROUGH.  BY EARLY AFTERNOON THE FEATURE WILL HAVE
MOVED OVER THE NORTHERN HIGH PLAINS WITH THE SOUTHERN PART WEAKENING
OVER SOUTHERN WYOMING.  A PACIFIC COLD FRONT ASSOCIATED WITH THE
SHORTWAVE TROUGH WAS LOCATED ACROSS WESTERN WYOMING AT 09Z AND WILL
MOVE THROUGH THE ENTIRE CWA BY 20Z.  DRIER AIR WILL SPREAD OVER THE
CWA BEHIND THE FRONT WITH MANY DEW POINTS IN THE 20S CURRENTLY IN
FAR WESTERN WYOMING AND IDAHO.  COLD AIR ADVECTION AND SUBSIDENCE
BEHIND THE SHORTWAVE TROUGH AND THE 250 MB JET OVER SOUTHERN WYOMING
SHOULD COMBINE TO CREATE BREEZY TO WINDY CONDITIONS LATER THIS
MORNING.  TEMPERATURES WILL COOL 3 TO 8 DEGREES FOR TODAY...WITH
THE WARMER READINGS STILL IN THE NEBRASKA PANHANDLE.  WILL GO AHEAD
AND UPGRADE THE PREVIOUSLY ISSUED FIRE WEATHER WATCH TO A RED FLAG
WARNING FOR THE ENTIRE CWA FROM 16Z TO 02Z.  WINDS DIMINSIH QUICKLY
THIS EVENING AND THEN SHIFT TO EAST OR SOUTHEAST.  THE RETURN BOUNDARY
LAYER WIND FLOW IS ABLE TO BRING SURFACE DEW POINTS BACK INTO THE 40S
TO MID 50S BY 12Z FRIDAY.  FRIDAY WILL BE A COOLER DAY WITH THE WEAK
UPSLOPE FLOW IN THE BOUNDARY LAYER.  THE NEXT UPSTREAM SHORTWAVE
TROUGH OVER THE PACIFIC NORTHWEST EARLY THIS MORNING IS HANDLED
SIMILARLY BY THE MODELS...WITH THE AXIS FROM WESTERN MONTANA TO
IDAHO FRIDAY AFTERNOON.  AHEAD OF THE FEATURE...A DIFFLUENT AND
INCREASINGLY MOIST SOUTHWEST FLOW ALOFT DEVELOPS AND WILL RIDE OVER
THE UPSLOPE WINDS NEAR THE SURFACE.  WILL BUMP UP POPS SOME FOR
FRIDAY AFTERNOON.

.LONG TERM...SATURDAY THRU THURSDAY...MILD TEMPERATURES EXPECTED
OVER THE WEEKEND ALONG WITH CHANCES FOR SHOWERS AND TSTRMS SAT AND
SAT NIGHT AS AN UPPER LEVEL TROF SWINGS ACROSS.  NAM FASTER WITH
THIS SYSTEM...MOVING IT BY 18Z SUNDAY WHILE GFS ABOUT 6-12 HOURS
SLOWER.  REGARDLESS...EXPECT CLEARING CONDITIONS DURING THE DAY
SUNDAY AS SFC HIGH BUILDS OVER THE REGION AND UPPER FLOW TURNS NW.
UPPER RIDGING THEN BUILDS AND SHIFTS EAST ACROSS THE CWA EARLY AND
MID PART OF NEXT WEEK WITH DRY AND WARMER CONDITIONS.

&&

.FIRE WEATHER...RED FLAG CONDITIONS SHOULD BE COMMON OVER THE ENTIRE
CWA BY LATE MORNING AND CONTINUE THROUGH THE EARLY EVENING.  AFTER
THE PASSAGE OF THE SHORTWAVE TROUGH AND COLD FRONT...DEW POINTS FALL.
SO EVEN THOUGH TEMPERATURES WILL BE SOMEWHAT COOLER THAN THOSE OF
WEDNESDAY...RELATIVE HUMIDITIES WILL STILL BE LOW.  WIND SPEEDS
WILL ALSO BE GREATER THAN ON WEDNESDAY WITH SOME GUSTS TO 35 OR 40
MPH...ESPECIALLY IN THE WYOMING PART OF THE CWA.  DECISION FOR
WARNING IS MADE EVEN EASIER DUE TO AT LEAST ONE LARGE FIRE IN THE
CWA AT THIS TIME IN SOUTHEAST WYOMING.
