AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
1102 AM MST MON DEC 26 2011

.UPDATE...18Z TAF ISSUANCE...AREAS OF MID TO HIGH CLOUDS WILL MOVE
MAINLY ACROSS THE SOUTHEAST WYOMING TERMINALS TODAY. SOUTHWEST TO
NORTHWEST WINDS WILL CONTINUE TO BE BREEZY THRU THIS AFTERNOON
WITH GUSTS 20 TO 35KTS COMMON. SOMEWHAT HIGHER VALUES WILL OCCUR
IN THE WIND CORRIDOR ALONG AND WEST OF THE LARAMIE RANGE. WINDS AT
THE AREA TERMINALS WILL EASE LATE THIS AFTERNOON AND EVENING...BECOMING
GUSTY AGAIN ACROSS SOUTHEAST WYOMING LATE TUESDAY MORNING.

&&

.PREV DISCUSSION... /ISSUED 929 AM MST MON DEC 26 2011/

UPDATE...
WIND WARNINGS HAVE BEEN ALLOWED TO EXPIRE AT 9 AM MST. WINDS HAVE
BEEN ON A DOWN TREND THE LAST SEVERAL HOURS AND ARE NOW BELOW WIND
WARNING CRITERIA. WINDS WILL REMAIN ON THE HIGH SIDE THE NEXT FEW
HOURS WITH GUSTS OF 40 TO 50 MPH...BUT WINDS WILL CONTINUE ON A
DOWN TREND INTO THE AFTERNOON.

PREV DISCUSSION.../ISSUED 613 AM MST MON DEC 26 2011/

UPDATE...
ADDED THE SOUTHERN LARAMIE RANGE AND ADJACENT EASTERN FOOTHILLS
TO THE HIGH WIND WARNING THIS MORNING AS A FEW SITES HAVE TOPPED
CRITICAL THRESHOLDS.

PREV DISCUSSION.../ISSUED 349 AM MST MON DEC 26 2011/

SHORT TERM...TODAY THROUGH WEDNESDAY...
A SHORTWAVE IS CURRENTLY MOVING ACROSS EASTERN MT AND NORTHERN WY.
MSAS DATA CONTINUES TO SHOW SFC PRESSURE FALLS ACROSS EASTERN WY
ASSOCIATED WITH THE SHORTWAVE.  SW SFC WINDS HAVE CONTINUED TO
INCREASE OVERNIGHT...AND THEY ARE INCHING CLOSER TOWARD WARNING
CRITERIA IN PLACES AROUND BORDEAUX AND ARLINGTON. THESE AREAS HAVE
BEEN GUSTING TO JUST ABOVE 50 MPH...SO THE HIGH WIND WARNING
THROUGH 9 AM LOOKS GOOD. A SHORTWAVE RIDGE MOVES OVER THE CWA THIS
AFTERNOON WITH A CORRESPONDING DECREASE IN THE SFC PRESSURE
GRADIENT...SO EXPECT A WEAKENING OF THE WINDS AFTER MID- MORNING.
TEMPS TODAY WILL BE SEASONAL WITH HIGHS IN THE LOW 40S EAST OF THE
LARAMIE RANGE.

THE NEXT IN A SERIES OF SHORTWAVES WILL MOVE ACROSS WY ON TUES
AFTN WITH SFC PRESSURE FALLS TO THE LEE OF THE LARAMIE RANGE.  THE
SFC PRESSURE GRADIENT CONTINUES TO STRENGTHEN TUES NIGHT AND THE
GFS PROGS AN INCREASE IN 700 MB WINDS TO 55 KTS.  THE WRKHGT PRODUCT
SHOWS THE 700 MB CRAIG TO CASPER GRADIENT AT 55 METERS BY 12Z WED.
THUS...EXPECT WIND HIGHLIGHTS TO BE NEEDED STARTING TUES NIGHT FOR
THE WIND PRONE AREAS OF ARLINGTON AND BORDEAUX. WHILE THERE WILL
BE NOTICEABLE INCREASE IN SFC WINDS ON WED...ZONES OUTSIDE
ARLINGTON AND BORDEAUX MAY NOT REACH WIND WARNING CRITERIA UNTIL
WED NIGHT WHEN MORE FAVORABLE CONDITIONS ARRIVE. AREAS TO THE EAST
OF THE LARAMIE RANGE WILL SEE ABOVE NORMAL TEMPS ON WED WITH THE
DOWNSLOPING WESTERLY WINDS AND 700 MB TEMPS ABOVE 0C. THE ONLY
OTHER STORY ON WED IS THE INCREASE IN PRECIP CHANCES IN THE SIERRA
MADRE AND SNOWY RANGES. INCREASING MIDLEVEL RH VALUES COMBINED
WITH STRONG WESTERLY WINDS WILL CONTRIBUTE TO FAVORABLE
OROGRAPHICS ALONG THESE RANGES.

LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...
ZONAL FLOW PLOWING INTO THE WESTERN CONUS WILL BE THE RESULT OF A
140+ KNOT JET CONFINED BETWEEN 30N AND 50N ACROSS THE CENTRAL
PACIFIC. THE RESULTANT IMPACT WILL BE A PERIOD OF VERY STRONG WINDS
THAT WILL LAST INTO SATURDAY AND SOME OROGRAPHICALLY ENHANCED LIGHT
SNOW OVER THE SIERRA MADRE/SNOWY RANGES. LLVL HEIGHT GRADIENTS WILL
CONTINUE TO TICK UPWARDS WEDNESDAY NIGHT AND PERSIST INTO THE DAY ON
THURSDAY AS A LEE-SIDE TROUGH DEVELOPS. CRAIG TO CASPER LLVL
GRADIENT VALUES CLIMB INTO THE 70 TO 85 METER RANGE...WHICH SUGGEST
PERHAPS SOME 70+ MPH VALUES NEAR ARLINGTON...BORDEAUX AS WELL AS
OVER THE SOUTHERN LARAMIE RANGE. MEANWHILE H7 PROGS SHOW PERSISTENT
75-80 KNOTS ALONG THE SPINE OF THE LARAMIE RANGE ON THURSDAY. HIGH
WINDS WILL LIKELY SPILL OUT INTO OTHER LOWER ELEVATIONS ACROSS
SOUTHEAST WYOMING ON WEDNESDAY NIGHT/THURSDAY AS WELL DUE TO THE
FAVORABLE SUBSIDENT RIGHT EXIT PERSISTING OVER THE AREA. WILL NO
DOUBT NEED WIND HIGHLIGHTS WEDNESDAY NIGHT AND THURSDAY AS IT
APPROACHES. BOTH THE ECMWF AND GFS HAVE A SHORTWAVE TROUGH PASSING
NORTH OF THE AREA BY LATE TUESDAY DRAGGING A WEAK SFC FRONT THROUGH
THE CWA. THIS WILL EFFECTIVELY BREAK UP THE TIGHT PRESSURE GRADIENT
AND PROVIDE A BRIEF WINDOW OF LESSER WINDS LATER THURSDAY NIGHT AND
FRIDAY. THE NEXT APPROACHING SHORTWAVE WILL KICK WINDS UP AGAIN FOR
FRIDAY NIGHT AND SATURDAY WITH LLVL CRAIG TO CASPER HEIGHT GRADIENTS
ONCE AGAIN CLIMBING INTO THE 60 TO 70 METER RANGE. SO EXPECT ANOTHER
HIGH WIND EVENT FOR FRIDAY NIGHT AND SATURDAY. THERE WILL BE A
PERIOD OF LIGHT SNOW ACROSS THE SNOWY/SIERRA MADRES AS AN AREA OF QG
ASCENT COMBINED WITH OROGRAPHIC LIFT. ANY SNOW ACCUMULATIONS WILL
REMAIN LIGHT...OF PERHAPS A COUPLE OF INCHES. MEDIUM RANGE GUIDANCE
DIFFER ON THE STRENGTH OF SATURDAYS SHORTWAVE...WITH THE ECMWF
STRONGER AND SLOWER AND THE GFS QUICKER AND WEAKER. FOR NOW HAVE
TRENDED PRECIPITATION CHANCES TOWARDS CLIMO. MID/UPPER-LEVEL RIDGE
WILL BUILD IN FOR THE END OF THE WEEKEND AND EARLY NEXT WEEK
BRINGING AN END TO THE STRONG WINDS AND ANY LINGERING SNOW CHANCES.
TEMPERATURES WILL REMAIN UNSEASONABLY WARM THROUGH THE PERIOD WITH
HIGHS IN THE 40S AND LOW 50S EAST AND 30S AND LOW 40S WEST.

FIRE WEATHER...
NO FIRE WEATHER CONCERNS AT THIS TIME DUE TO THE RECENT SNOWFALL
ALONG WITH THE NON CRITICAL FUELS AND RELATIVE HUMIDITY VALUES
GENERALLY ABOVE 30 PERCENT.  WINDY CONDITIONS IN THE WIND PRONE
AREAS NEAR ARLINGTON AND BORDEAUX WILL EXIST THROUGH THIS MORNING
WITH A GENERAL DECREASE DURING THE AFTERNOON. WINDY TO VERY WINDY
CONDITIONS ARE EXPECTED AT TIMES STARTING TUESDAY NIGHT THROUGH
SATURDAY.
