AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
313 AM MST SUN JAN 11 2009

.SHORT TERM...TODAY THROUGH MONDAY...
MODELS ARE FAIRLY SIMILAR FOR THIS PART OF THE FORECAST AND HAVE
GOOD RUN TO RUN CONSISTENCY.  THE LARGE RIDGE ALOFT OVER THE EASTERN
PACIFIC EARLY THIS MORNING WILL CONTINUE TO BUILD AND MOVE SLOWLY
EAST THROUGH 00Z TUESDAY.  A SHORTWAVE TROUGH IS CURRENTLY MOVING
OVER THE TOP OF THE RIDGE IN THE GULF OF ALASKA AND WILL MOVE OVER
THE NORTHERN PLAINS LATE TONIGHT AND MONDAY.  THE CLIPPER SYSTEM
WILL MOVE THE ASSOCIATED SURFACE LOW FROM WEST CENTRAL ALBERTA AT
12Z TODAY TO THE EASTERN DAKOTAS 12Z MONDAY.  A SHALLOW CANADIAN
POLAR FRONT WILL BACK INTO AT LEAST THE EAST PART OF THE CWA LATE
TONIGHT AND MONDAY MORNING.  AT THIS TIME IT APPEARS THAT THERE
WILL BE ENOUGH MOISTURE...JET DYNAMICS AND MID LEVEL FRONTOGENESIS
TO PRODUCE A PERIOD OF LIGHT SNOW MAINLY OVER AND EAST OF THE
LARAMIE RANGE LATE TONIGHT AND MONDAY MORNING.  THE LIGHT SNOW WILL
LINGER THROUGH THE AFTERNOON HOURS ALONG THE LARAMIE RANGE.  SURFACE
HIGH PRESSURE BUILDS INTO THE HIGH PLAINS AND WILL IMPROVE
CONDITIONS OVER THE REST OF THE EAST PART OF THE CWA MONDAY
AFTERNOON.  SNOWFALL WILL BE LESS THAN AN INCH...WITH LARGER
ACCUMULATIONS OVER AND NEAR THE LARAMIE RANGE.  THE NORTHWEST FLOW
ALOFT WILL CONTINUE TO PRODUCE OROGRAPHIC SNOW OVER THE SNOWY RANGE
THROUGH MONDAY...WITH SEVERAL INCHES OF ACCUMULATING SNOW LIKELY.
OTHERWISE...THE MAIN ISSUE FOR THIS PART OF THE FORECAST WILL STILL
BE THE WINDS.  CURRENTLY KARL IS GUSTING TO 50 MPH WITH THE LOWEST
GATES OF THE MEDICINE BOW PROFILER AT 45 KNOTS.  THE LOW LEVEL
HEIGHT DIFFERENCES BETWEEN KCAG AND KCPR REMAIN MARGINAL THROUGH
TONIGHT AND SO WILL KEEP WINDS JUST BELOW CRITERIA DURING THAT
TIME.  THE STRONGER WINDS WILL SHIFT OVER THE EAST PART OF THE CWA
BY MONDAY AS THE FLOW ALOFT BECOMES MORE NORTHERLY AND THE 300 MB
JET IS OVER THE AREA.  WIND HIGHLIGHTS MAY BE NEEDED OVER THE EAST
PART OF THE CWA BY MONDAY.  FOR NOW HAVE GUSTS BETWEEN 45 AND 50
MPH AND A WIND ADVISORY MIGHT NEED TO BE CONSIDERED FOR THE
PANHANDLE.  TEMPERATURES TODAY AND TONIGHT WILL REMAIN ABOVE NORMAL
WITH COOLER TEMPERATURES IN MOST AREAS FOR MONDAY.

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY
MAINLY DRY CONDITIONS WILL PREVAIL ACROSS THE CWA THROUGH THE
EXTENDED PERIOD.  THE ONLY EXCEPTION BEING A CHANCE OF SNOW ACROSS
THE NORTHERN ZONES AND THE MOUNTAINS TUES NIGHT AND WED.  NW FLOW
WILL DOMINATE THE PERIOD WITH A HIGH AMPLITUDE RIDGE OFF THE WEST
COAST AND A DEEP UPPER TROUGH OVER THE EASTERN HALF OF THE U.S.  A
COLD FRONT IN ASSOCIATION WITH A DISTURBANCE WILL MOVE ACROSS THE
AREA TUES NIGHT AND WED.  WARMER TEMPERATURES WILL OCCUR FOR FRI AND
SAT AS THE FRONTAL BOUNDARY MOVES TO THE EAST AND A SURFACE LEE
TROUGH SETS UP.  WINDY CONDITIONS WILL ALSO OCCUR THROUGHOUT THE
EXTENDED PERIOD.  A DISTURBANCE WILL POSSIBLY MOVE ACROSS THE
FORECAST AREA ON SAT...BUT THE TRACK OF THE FEATURE REMAINS
UNCERTAIN AT THIS TIME.  HIGH TEMPERATURES WILL BE AROUND 10 DEGREES
ABOVE NORMAL ON TUES...COOLING TO AROUND NORMAL FOR WED AND
THUR...AND 7 TO 10 DEGREES ABOVE NORMAL FOR FRI AND SAT.

&&

.AVIATION...WEST WINDS WILL GUST AS HIGH AS 45 KNOTS OVER AND NEAR
THE SNOWY AND LARAMIE RANGES AGAIN TODAY AND TONIGHT.  THE SURFACE
WINDS WILL SHIFT TO THE NORTHWEST LATE TONIGHT AND MONDAY WITH GUSTS
TO 40 KNOTS LIKELY EAST OF THE LARAMIE RANGE.  VFR CONDITIONS OVER
THE CWA WILL LOWER TO MVFR CEILINGS AND VISIBILITIES IN LIGHT SNOW
FOR A PERIOD LATE TONIGHT AND MONDAY.  THOSE CONDITIONS WILL PERSIST
INTO MONDAY AFTERNOON OVER KLAR...KCYS AND KEAN.
