AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
339 AM MDT SUN MAR 15 2009

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...
A BENIGN SHORT WAVE WILL MOVE ACROSS THE AREA TODAY WITH ONLY SOME
MID AND HIGH LEVEL CLOUDS ASSOCIATED WITH THIS FEATURE. GUSTY
DOWNSLOPE WINDS WILL CREATE VERY DRY CONDITIONS ACROSS THE AREA.
FOR TONIGHT THROUGH MON NIGHT...WESTERLY FLOW WILL CONTINUE ALOFT.
700 MB WINDS WILL BE AROUND 50 KNOTS AND SURFACE WINDS WILL BORDER
HIGH WIND WARNING CRITERIA. LOCAL AREAS SUCH AS BORDEAUX AND
ARLINGTON WILL PROBABLY REACH HIGH WIND CRITERIA. WILL HOLD OFF ON
ISSUING A HIGH WIND WATCH DUE TO IT BEING A BORDERLINE...LOCAL
EVENT IN ADDITION TO AVOID OVERLAPPING RED FLAG WARNING WITH A
HIGH WIND WATCH. THE DRY AND WINDY CONDITIONS WILL CONTINUE
THROUGH MON NIGHT. HIGH TEMPERATURES WILL BE FROM 10 TO 15 DEGREES
ABOVE NORMAL FOR TODAY...AND 15 TO 20 DEGREES ABOVE NORMAL FOR MONDAY.

.LONG TERM...TUESDAY THROUGH SATURDAY...
A 145KT H3 JET ORIENTED ALONG THE U.S./CANADIAN BORDER WILL
RESULT IN A ZONAL PATTERN ACROSS THE WESTERN TWO THIRDS OF THE
CONUS AT THE BEGINNING OF THE PERIOD. BREEZY CONDITIONS AND
HEIGHTENED FIRE WEATHER CONCERNS WILL CONTINUE ON TUESDAY WITH
SLIGHTLY COOLER TEMPERATURES BENEATH INCREASING CLOUDS. A WEAK
COOL FRONT WILL DROP SOUTH TUESDAY NIGHT...WHICH WILL EFFECTIVELY
BREAK UP THE STRONG WESTERLY SFC GRADIENT THAT AFFECTED THE REGION
EARLIER IN THE WEEK. BOTH THE NAM/GFS HINT AT SOME WEAK
INSTABILITY ALONG THIS BAROCLINIC BOUNDARY IN WRN NE TUE EVENING.
HOWEVER MODELS HAVE BEEN POOR IN CAPTURING SFC MOISTURE...OR LACK
THEREOF THUS FAR THIS SEASON...SO BELIEVE THAT THESE INSTABILITY
PARAMETERS ARE OVERDONE...SO HAVE LEFT DRY FOR NOW. BOUNDARY WILL
REACH THE LARAMIE RANGE MIDDAY WEDNESDAY...BUT STILL EXPECT LITTLE
MORE THAN INCREASING CLOUD-COVER. BY THURSDAY...A DIRTY RIDGE WILL
BEGIN TO DEVELOP OVER THE REGION WHICH WILL KEEP DRY CONDITIONS
GOING INTO THE WEEKEND. MEDIUM RANGE MODELS BEGIN TO DIVERGE ON
SATURDAY...WITH THE ECMWF DEVELOPING A STRONG RIDGE OVER THE
INTERMOUNTAIN WEST WHICH WOULD MEAN SLOWER EASTWARD PROGRESSION OF THE
EASTERN PACIFIC TROUGH. MEANWHILE...THE GFS IS MUCH WEAKER WITH
THIS UPSTREAM RIDGE...WHICH ALLOWS THE NEXT TROUGH TO BE 12 TO 18
HOURS AHEAD OF THE ECMWF. IN EITHER SCENARIO...DRY CONDITIONS WILL
CONTINUE ON SATURDAY...HOWEVER IF THE ECMWF VERIFIES...TEMPERATURES WILL
BE WARMER THAN CURRENTLY FORECASTED. TEMPERATURES WILL BE
PERSISTENT THROUGH THE PERIOD WITH HIGHS GENERALLY IN THE MID 50S
WEST...AND LOW TO MID 60S EAST.
