310 AM MST SAT DEC 1 2012
.SHORT TERM...TODAY THROUGH SUNDAY NIGHT...
MILD TEMPERATURES CAN BE EXPECTED OVER THE CWA THROUGH SUNDAY NIGHT
ALONG WITH STRONG WINDS ALONG AND WEST OF THE LARAMIE RANGE. ALSO
SNOW WILL FALL OVER MAINLY THE SNOWY AND SIERRA MADRE RANGES EARLY
THIS MORNING AS WELL AS SUNDAY AFTERNOON AND SUNDAY NIGHT.
INITIAL SHORTWAVE TROUGH WAS OVER FAR EASTERN WYOMING EARLY THIS
MORNING. MOUNTAIN LIGHT SNOW AS WELL AS CLOUD COVER HAS DECREASED
BEHIND THE FEATURE. WINDS HAVE YET TO BECOME STRONG OVER AND NEAR
THE LARAMIE RANGE WITH THE TROUGH PASSAGE. AT THIS TIME...HIGH
WINDS IN THOSE AREAS APPEARS UNLIKELY AND WILL CANCEL THE HIGH
WIND WARNING WITH FORECAST ISSUANCE. EVEN IN THE KARL AREA...HIGH
WINDS HAVE BEEN MARGINAL...BUT WILL KEEP THE WARNING GOING UNTIL
18Z. WEAK COLD AIR ADVECTION BEHIND THE SHORTWAVE TROUGH MAY HELP
TO PRODUCE HIGH TEMPERATURES A FEW DEGREES COOLER THAN THOSE OF
FRIDAY.
HEIGHTS ALOFT RISE SLOWLY THIS AFTERNOON THROUGH SUNDAY OVER THE
ROCKIES. LIGHTER WINDS...DRY CONDITIONS AND WARMER TEMPERATURES
FOR SUNDAY SHOULD RESULT. HIGHS ON SUNDAY WILL BE 10 TO 20 DEGREES
ABOVE NORMAL. WINDS WILL INCREASE ONCE AGAIN OVER THE CWA BY MID
MORNING SUNDAY OVER THE CWA...ESPECIALLY ALONG AND WEST OF THE
LARAMIE RANGE. THE WINDS WILL BE CREATED BY A TIGHTENING OF THE
SURFACE PRESSURE GRADIENT IN RESPONSE TO A SURFACE LOW FORMING TO
THE NORTH OF THE CWA. THE 700 MB WINDS ALSO INCREASE ON SUNDAY
WITH SPEEDS AS HIGH AS 55 KNOTS ON THE GFS. WILL GO AHEAD AND
ISSUE A HIGH WIND WATCH FOR 15Z SUNDAY TO 06Z MONDAY FOR SOME AREAS
ALONG AND WEST OF THE LARAMIE RANGE...WITH GUSTS TO 65 MPH LIKELY.
A SHORTWAVE TROUGH CURRENTLY OVER THE EASTERN PACIFIC WILL MOVE
OVER THE CENTRAL ROCKIES SUNDAY NIGHT AS IT FILLS. THE ASSOCIATED
MOISTURE AND LIFT WILL PRODUCE WIDESPREAD OVER THE SNOWY AND SIERRA
MADRE RANGES STARTING AS EARLY AS SUNDAY AFTERNOON. THE SNOW LEVEL
WILL INITIALLY BE HIGH SUNDAY AFTERNOON AND GRADUALLY LOWER SUNDAY
NIGHT. EVEN AT 06Z MONDAY...MODELS ARE STILL AT OR ABOVE 0C AT
700 MB. OVER THE LOWER ELEVATIONS...THE PRECIPITATION TYPE MAY BE
IN THE FORM OF RAIN THROUGH EARLY SUNDAY NIGHT. THE WARM READINGS
SHOULD LIMIT SNOW ACCUMULATION...ESPECIALLY EARLY SUNDAY NIGHT AND
WILL KEEP 3 TO 5 INCHES OVER THOSE RANGES THROUGH 12Z MONDAY.
.LONG TERM...MONDAY THROUGH FRIDAY.
MONDAY...WINDS WILL BE DECREASING THROUGH THE DAY AS THE SURFACE AND
LOW LEVEL GRADIENTS RELAX. DRYING OUT AS WELL AS THE LOW AND MID
LEVELS DRY OUT DURING THE DAY.
TUESDAY...WINDS WILL CRANK UP AGAIN AND MAY APPROACH OR EXCEED HIGH
WIND CRITERIA AT TYPICALLY WIND PRONE LOCATIONS AS SURFACE THROUGH
700 MB GRADIENTS STRENGTHEN MARKEDLY. THE WINDS WILL ALSO PRODUCE A
DECENT WARMING TREND AS PER THICKNESS AND 700 MB TEMPERATURE TRENDS.
CONTINUED DRY WITH LACK OF LOW AND MID LEVEL MOISTURE...THOUGH
SHOULD SEE PLENTY OF MOUNTAIN WAVE CLOUDS AS HIGH LEVEL MOISTURE
STREAMS EASTWARD IN THE FAST FLOW ALOFT.
WEDNESDAY...HEIGHTS ALOFT FALL IN THE STRONG ZONAL FLOW AS THE NEXT
SHORTWAVE TROUGH ALOFT SKIMS ACROSS THE ROCKIES. LOOKS LIKE ENOUGH
MID LEVEL MOISTURE IN THE FAST FLOW ALOFT TO PRODUCE ISOLATED TO
SCATTERED SHOWERS OVER THE SNOWY AND SIERRA MADRE RANGES...DRY
ELSEWHERE. CONTINUED WINDY WITH IMPRESSIVE SURFACE GRADIENTS AND
DECENT LOW AND MID LEVEL WINDS.
THURSDAY...RELATIVELY STRONG COLD FRONT SWEEPS ACROSS THE REGION
EARLY IN THE DAY AND WITH ADEQUATE LOW AND MID LEVEL MOISTURE AND
STRONG COLD AIR ADVECTION...WE SHOULD SEE AT LEAST SCATTERED SHOWERS
ALONG AND BEHIND THE COLD FRONT ALONG WITH COLD NORTH AND NORTHWEST
WINDS IN THE WAKE OF THE COLD FRONT.
FRIDAY...RETURN SOUTHERLY LOW LEVEL WINDS DEVELOP LATE IN THE DAY
THOUGH STILL ON THE COLD SIDE IN THE WAKE OF THE THURSDAY COLD
FRONT. DRY DUE TO LIMITED LOW AND MID LEVEL MOISTURE.
