AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
1047 AM MST TUE JAN 27 2009

.DISCUSSION...WINDS HAVE CONTINUED TO INCREASE OVER AND NEAR
THE MOUNTAINS WITH KBRX GUSTING AS HIGH AS 59 MPH AS OF 1025 AM.
THE STRONG WINDS AND THE FRESH SNOW COVER WILL COMBINE TO PRODUCE
WIDESPREAD BLOWING AND DRIFTING SNOW AND NEAR ZERO VISIBILITIES
MAINLY OVER AND NEAR THE MOUNTAINS.  SOME ROADS IN THE CWA HAVE
BEEN CLOSED DUE TO THE BLIZZARD CONDITIONS.  THE WINDS WILL BE AS
STRONG OR STRONGER TONIGHT AND SO HAVE UPGRADED THE PREVIOUSLY
ISSUED HIGHLIGHTS FOR A BLIZZARD WARNING FOR ALL BUT PORTIONS
OF LARAMIE COUNTY AND MOST OF CONVERSE COUNTY WHERE A WINTER
WEATHER ADVISORY FOR BLOWING SNOW WILL REMAIN IN EFFECT.  THE
HIGHLIGHTS CONTINUE THROUGH 12Z WEDNESDAY.

&&

.PREVIOUS DISCUSSION.../ISSUED AT 443 AM MST TUE JAN 27 2009/...

SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...
UPDATING THE FORECAST DISCUSSION TO ACCOUNT FOR EARLIER THAN
EXPECTED START TO THE WINTER WEATHER ADVISORY FOR BLOWING SNOW.

MAIN FORECAST CONCERN TODAY IS THE EXPECTED DEVELOPMENT OF WINDS
AND BLOWING SNOW ACROSS THE AREA AS A SURFACE TROUGH DEVELOPS IN
THE LEE OF THE MOUNTAINS. THE SURFACE PRESSURE FALLS ARE
CURRENTLY GREATEST ALONG THE HIGH LINE OF MONTANA AHEAD OF THE
NEXT QUICK MOVING DISTURBANCE IN THE UPPER LEVEL FLOW. THIS
DISTURBANCE IS JUST MOVING ONSHORE IN CENTRAL BRITISH COLUMBIA
EARLY THIS MORNING AND WILL BRING A WEAK COLD FRONT ACROSS THE
FORECAST AREA EARLY WEDNESDAY. PRECIPITATION CHANCES WILL LINGER
WITH THIS UPPER LEVEL DISTURBANCE THROUGH WEDNESDAY NIGHT.

RETURNING TO THE TOPIC OF WINDS FOR TODAY...AS THE SURFACE
PRESSURE FALLS INCREASE ACROSS SOUTHEAST WYOMING TODAY THERE WILL
BE SIGNIFICANT BLOWING AND DRIFTING OF THE SNOW WHICH FELL OVER
THE WEEKEND. HAVE DECIDED TO ISSUE A WINTER WEATHER ADVISORY FOR
BLOWING SNOW ACROSS MOST OF THE CENTRAL AND WESTERN PORTION OF
THE AREA THROUGH 5 AM MST WEDNESDAY. WILL HOLD OFF ON THE START
TIME FOR THE CHEYENNE FOOTHILLS UNTIL 8 AM MST SINCE WINDS WILL
LIKELY TAKE A BIT LONGER TO DEVELOP THAT FAR SOUTH ALONG THE LEE
OF THE LARAMIE RANGE.

IN ADDITION...THE HIGH WIND FORECAST AIDS ARE INDICATING
SUFFICIENT PRESSURE GRADIENTS TO SUPPORT WINDS EXCEEDING HIGH
WIND CRITERIA BEGINNING TONIGHT. HAVE THEREFORE ALSO POSTED A
HIGH WIND WATCH FOR THE USUAL AREAS IN CARBON COUNTY...IN THE
LARAMIE RANGE...AND PLATTE COUNTY. 700 MB WINDS WILL REACH AROUND
50 KNOTS TONIGHT AND INTO EARLY WEDNESDAY BEFORE THE COLD FRONT
PASSES. HAVE ENDED THE WATCH AT 5 AM MST WEDNESDAY TO COINCIDE
WITH THE END OF THE BLOWING SNOW ADVISORY. THE END TIMES OF BOTH
HIGHLIGHTS MAY NEED TO BE EXTENDED...AS WINDS BEHIND THE COLD
FRONTAL PASSAGE SHOULD AT LEAST BRIEFLY REMAIN GREAT ENOUGH TO
CAUSE CONTINUED BLOWING SNOW AND REDUCED VISIBILITY. THE
LIKELIHOOD OF HIGH WIND CRITERIA BEING EXCEEDED WILL DIMINISH
AFTER THE FRONTAL PASSAGE EARLY WEDNESDAY.

THE BEST CHANCES FOR PRECIPITATION THROUGH THURSDAY MORNING WILL BE
IN THE MOUNTAIN AREAS AS THE NORTHWEST FLOW ALOFT SUPPORTS
OROGRAPHIC SNOW SHOWERS. AS THE UPPER LEVEL DISTURBANCE APPROACHES
EARLY WEDNESDAY...THE LEFT EXIT REGION OF THE JET STREAK WILL
PROVIDE FOR THE BEST PRECIPITATION CHANCES IN THE MOUNTAINS DURING
THE SHORT TERM. WILL CONTINUE TO MENTION SNOW LIKELY IN THE
MOUNTAINS THROUGH THURSDAY NIGHT AS ANOTHER STRONGER JET STREAK WILL
BE PROVIDING SUPPORT FOR SNOW SHOWERS. AN ADDITIONAL 6 TO 9 INCHES
OF SNOWFALL ACCUMULATION WILL BE POSSIBLE THROUGH EARLY THURSDAY IN
THE SNOWY AND SIERRA MADRE RANGES. ELSEWHERE...PRECIPITATION CHANCES
WILL INCREASE WEDNESDAY NIGHT WITH THE APPROACH OF THE CYCLONIC
CURVATURE ASSOCIATED WITH THE UPPER LEVEL DISTURBANCE.

TEMPERATURES WILL BE MUCH WARMER TODAY...BUT MOST AREAS WILL STILL
BE 10 TO 20 DEGREES BELOW NORMAL. THE WARMING TREND WILL CONTINUE
WEDNESDAY AS TEMPERATURES WARM TO ONLY SLIGHTLY BELOW NORMAL LATE
JANUARY VALUES.

LONG TERM...THURSDAY THROUGH MONDAY
NW FLOW WILL BE ALOFT OVER THE CWA ON THUR WITH AN UPPER RIDGE ALONG
THE WEST COAST.  DOWNSLOPE WINDS AT THE SURFACE WILL RESULT IN DRY
CONDITIONS ACROSS THE AREA.  VERY WINDY CONDITIONS WILL PERSIST
DURING THE DAY.  THE FRONTAL BOUNDARY WILL ALSO MOVE EAST AS A WARM
FRONT DURING THE DAY LEADING TO WARMER TEMPERATURES ACROSS THE
FORECAST AREA.  ON FRI...NW FLOW WILL CONT ALOFT AS THE UPPER RIDGE
MOVES OVER THE WESTERN U.S.  A SURFACE LEE TROUGH WILL DEVELOP OVER
THE EASTERN PORTION OF THE CWA RESULTING IN WINDY AND DRY CONDITIONS
ACROSS THE AREA.  FOR SAT...THE UPPER RIDGE OVER THE WEST WILL BREAK
DOWN AND FLATTEN OUT IN RESPONSE TO AN UPPER TROUGH MOVING ACROSS
SOUTHERN CANADA.   A COLD FRONT WILL MOVE ACROSS THE FORECAST AREA
SAT NIGHT/SUN MORNING.  A SLIGHT CHANCE OF SNOW CAN BE EXPECTED IN
THE SOUTHERN MOUNTAINS SATURDAY NIGHT. MAY HAVE TO INCREASE POPS SAT
NIGHT AS UPSLOPE FLOW DEVELOPS BEHIND SURFACE COLD FRONT.  SUN AND
MON WILL BE DRY WITH NW FLOW ALOFT AS THE UPPER TROUGH OVER CANADA
MOVES SE INTO THE MIDWEST.  THE UPPER RIDGE WILL THEN REBUILD OVER
THE WESTERN U.S.  HIGH TEMPERATURES WILL BE AROUND NORMAL ON
THUR...10 TO 15 DEGREES ABOVE NORMAL FOR FRI AND SAT...AND 5 TO 10
DEGREES ABOVE NORMAL ON SUN AND MON.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL THROUGH AROUND 18Z TODAY...BUT
CONDITIONS WILL GRADUALLY DETERIORATE THIS AFTERNOON WEST OF A
LUSK TO CHEYENNE LINE AS WINDS CAUSE BLOWING SNOW AND REDUCED
VISIBILITIES. CONDITIONS WILL LIKELY BE REDUCED TO MVFR WITH
AREAS OF IFR DUE TO THE BLOWING SNOW TODAY AND TONIGHT. MOUNTAIN
OBSCURATION WILL ALSO BE POSSIBLE AS SNOW SHOWERS WILL REMAIN
POSSIBLE TODAY...AND EVEN LIKELY BY AROUND SUNRISE WEDNESDAY
MORNING.
