AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
942 AM MST THU JAN 10 2008

.DISCUSSION...WINDS HAVE GRADUALLY PICKED UP OVER THE CWA...NAMELY
BETWEEN KARL AND KBRX.  LATEST INFORMATION FROM KARL SHOWS A GUST TO
65 MPH.  SURFACE PRESSURE GRADIENT AND WINDS ALOFT BOTH LOOK TO
INCREASE THIS AFTERNOON.  SO HAVE WENT AHEAD AND ISSUED A HIGH WIND
WARNING FOR THAT AREA UNTIL 01Z.

.PREVIOUS DISCUSSION.../ISSUED AT 140 AM MST THU JAN 10 2008/

SHORT TERM...TODAY THROUGH FRIDAY NIGHT.
FAIRLY STRAIGHT FORWARD SITUATION FOR THE SHORT TERM FORECAST
WITH WINDS BEING THE MAIN CONCERN THROUGH THE REST OF THE WEEK.
UPPER LEVEL NORTHWEST FLOW WILL BACK SLIGHTLY TODAY AS A WEAK
MID-LEVEL DISTURBANCE PASSES THE AREA BENEATH A SHORT-WAVE RIDGE
ALOFT. 700 MB WINDS WILL INCREASE TO AROUND 50 KNOTS LATE THIS
AFTERNOON THROUGH TONIGHT. HAVE KEPT THE WIND SPEED FORECAST BELOW
HIGH WIND CRITERIA BECAUSE IT CONTINUES TO LOOK LIKE THE POSITION
OF THE UPPER JET SHOULD ACT TO LIMIT SUBSIDENCE ACROSS THE
AREA...WHICH WILL ALSO LIMIT THE STRENGTH OF THE WINDS AT THE
SURFACE. WINDY CONDITIONS WILL OCCUR THOUGH...AND FORECAST WINDS
WILL BE JUST BELOW HIGH WIND CRITERIA. ONLY WILL HAVE A SLIGHT
CHANCE FOR MOUNTAIN SNOW SHOWERS THIS MORNING FOR THE LIMITED
CHANCE FOR AN OROGRAPHIC CAUSED SNOW SHOWER. THEN WILL QUICKLY
RAISE PRECIPITATION CHANCES THIS AFTERNOON AND INCLUDE LIKELY SNOW
SHOWERS IN THE MOUNTAINS TONIGHT THROUGH FRIDAY AS FAVORABLE JET
DYNAMICS...UPPER LEVEL DISTURBANCE...AND OROGRAPHIC ENHANCEMENT
WILL KEEP PRECIPITATION OVER THE HIGHER TERRAIN. MODEL FORECASTS
FOR LIQUID EQUIVALENT AMOUNTS ARE VERY LIMITED...AND THEREFORE
HAVE KEPT SNOW AMOUNTS QUITE LOW. BY SATURDAY MORNING...48 HOUR
NEW SNOW ACCUMULATIONS OF AROUND 6 TO 10 INCHES IN THE HIGHER
TERRAIN...AND 2 TO 4 INCHES OVER LOWER ELEVATIONS OF CARBON COUNTY
CAN BE EXPECTED. EVEN LIGHTER ACCUMULATIONS CAN BE EXPECTED IN THE
LOWER ELEVATION AREAS OF ALBANY COUNTY.

LONG TERM...SATURDAY THRU WEDNESDAY...A COUPLE OF WEAK IMPULSES WILL
DROP SE ACROSS THE REGION SATURDAY INTO SUNDAY ON DOWNSIDE OF WEST
COAST UPPER RIDGE BUT EXPECT LITTLE EFFECT FROM THEM BEYOND KEEPING
SOME MTN SNOW SHOWERS GOING AND BRINGING A PACIFIC COOL FRONT ACROSS
THE CWA SATURDAY.  MILDER AND MAINLY DRY CONDITIONS LOOKS TO SPREAD
OVER THE CWA EARLY NEXT WEEK AS WEST CONUS UPPER RIDGE SHIFTS EAST
WHILE WEAKENING.  SIGNIFICANT POLAR SURGE MAY THEN INVADE THE REGION
MIDWEEK AS POTENT SHORTWAVE DROPS ACROSS SRN CANADA AND ALLOWS A
MORE POLAR ORIGINATED SFC HIGH TO SINK SE ALONG THE ROCKY MTN
CHAIN.  WILL SHADE IN SOME LOW POPS ALONG UPSLOPE FAVORED AREAS OF
MAINLY SE WY FOR WEDS BUT NOT BE TOO AGGRESSIVE RIGHT NOW DUE TO
TIMING UNCERTAINTIES THAT FAR OUT.

.AVIATION...
AREAS OF MVFR CEILINGS WILL CONTINUE TO BE PRESENT THROUGH AROUND
900 AM MST THIS MORNING...BUT OTHERWISE VFR CONDITIONS AND GUSTY
WINDS CAN BE EXPECTED THROUGH THE PERIOD. AREAS OF MOUNTAIN
