AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
300 PM MST TUE JAN 2 2007

.SHORT TERM...TONIGHT THROUGH THURSDAY. STRONG WEST TO SOUTHWEST
WINDS WILL CONTINUE PORTIONS OF WYOMING TONIGHT...PARTICULARLY
ALONG THE HIGH WIND CORRIDOR BETWEEN CHUGWATER AND GLENDO.
ALTHOUGH WIND GUSTS AT BORDEAUX HAVE DROPPED DOWN TO 50 MPH AT 2
PM MST...THEY WILL PERIODICALLY JUMP UP TO AROUND 6O MPH THROUGH
THE LATE AFTERNOON BEFORE DECREASING IN THE EARLY EVENING. THERE
IS A SHORT BREAK IN GUSTY WINDS OVERNIGHT...BUT THE SURFACE
PRESSURE GRADIENT BEGINS TO TIGHTEN ACROSS SOUTHEAST WYOMING ON
WEDNESDAY THROUGH THURSDAY. MODELS INDICATE THE 700MB AND 850MB
HEIGHT DIFFERENCES REACHING MORE THAN 60 METERS WITH THE PEAK
HEIGHT DIFFERENCES ON WEDNESDAY AFTERNOON. BOTH THE NAM AND GFS
SHOWED 700MB WINDS INCREASING TO AROUND 55 KNOTS DURING WEDNESDAY
AFTERNOON AND CONTINUING THROUGH THURSDAY MORNING. THE COMBINATION
OF THE TIGHTENING SURFACE PRESSURE GRADIENT AND THE NOSE OF A 160
KNOT JET AT 300M MOVING ACROSS SOUTHERN WYOMING WILL BRING STRONG
WINDS ACROSS PORTIONS OF WYOMING. THE GREATEST IMPACT WILL BE
ALONG THE INTERSTATE 25 BETWEEN CHUGWATER AND GLENDO AND ALONG
INTERSTATE 80 NEAR VEDAUWOO. THUS WILL BE ISSUING A HIGH WIND
WATCH FOR THESE AREA ON WEDNESDAY AND WEDNESDAY NIGHT. ALTHOUGH
THE MAIN IMPACT WILL BE WINDS IN THE SHORT TERM...WILL ALSO GET
SOME MOUNTAIN SNOW SHOWERS DEVELOPING WEDNESDAY NIGHT IN
ASSOCIATION WITH JET DYNAMICS AND CONTINUE INTO THURSDAY AHEAD OF
THE APPROACHING UPPER LEVEL TROUGH. AS FOR TEMPERATURES...HIGHS
WILL BE SLIGHT WARMER FOR WEDNESDAY WITH TEMPERATURES IN THE MID
40S FOR AREAS EAST THE LARAMIE RANGE AND IN THE 30S WEST OF THE
LARAMIE RANGE. LOW TEMPERATURES WILL BE WARMER WITH THE INCREASED
WINDS DURING THE NIGHT AND EARLY MORNING. FOR
THURSDAY...TEMPERATURES WILL BE A COUPLE DEGREES COOLER WITH THE
INCREASING CLOUDS AND APPROACHING FRONT.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...NW UPPER FLOW WILL
STEADILY BACK AROUND TO THE SW AHEAD OF A STRENGTHENING TROUGH
THURSDAY EVENING.  AN ASSOCIATED COLD FROPA IS SLATED FOR EARLY
FRIDAY MORNING.  THE STORM WILL DEVELOP BASICALLY OVERHEAD...AND THE
GFS AND NAM DEPICT STRONG FRONTOGENETIC FORCING ACROSS THE PLAINS
THROUGH THE MORNING HOURS OF FRIDAY.  THE SYSTEM WILL MOVE
RAPIDLY...SO NOT MUCH TIME WILL EXIST FOR SIGNIFICANT BOUNDARY LAYER
MOISTENING...BUT IT APPEARS 2 TO 4 INCHES OF SNOW COULD FALL THAT
MORNING.  SFC HIGH PRESSURE WILL HASTILY BUILD BEHIND THE SYSTEM
FRIDAY EVENING...AND WINDS WILL BE THE ONLY CONCERN THEREAFTER.
LOOKS TO BE A VERY WINDY FEW DAYS WITH PERSISTENT HIGH PRESSURE OVER
THE DESERT SW AND FAST NW FLOW ALOFT.

&&

.AVIATION...VFR THROUGH 5 AM WEDNESDAY MORNING. MID/HIGH LEVEL
CLOUDS WILL CONTINUE TO INCREASE THROUGH THURSDAY. SURFACE WINDS
HAVE ALREADY INCREASED ACROSS WIND PRONE AREAS...PARTICULARLY
AREAS EXTENDING FROM CHUGWATER TO DOUGLAS AND ALSO FOR AREAS
AROUND THE MOUNTAINS. EXPECT WINDS TO CONTINUE TO INCREASE FOR
WEDNESDAY AND WEDNESDAY NIGHT AS THE PRESSURE GRADIENT BEGINS TO
TIGHTEN AND A STRONG JET NUDGES INTO THE STATE.
