AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
230 PM MST FRI DEC 30 2005

.SHORT TERM...TONIGHT THROUGH SUNDAY...A TRANSIENT RIDGE WILL WARM
THE PLAINS AND BRING SHOWERS TO THE WEST OVERNIGHT AND SATURDAY.
APPEARS A PROLONGED PERIOD OF SNOW WILL SET UP IN THE SNOWY RANGE
OVERNIGHT INTO TOMORROW WITH GUSTY WINDS...THUS A SNOW AND BLSN ADVY
HAS BEEN POSTED FOR THAT ZONE THROUGH SATURDAY AFTERNOON. NAM AND
GFS SNOW TOTALS BECOME PROLIFIC SATURDAY NIGHT WITH EVEN MORE
WIND...SO A WINTER STORM HIGHLIGHT MAY BE NEEDED BY A LATER SHIFT IF
THE TREND CONTINUES.  THE RIDGE WILL FLATTEN AND TRANSITION INTO A
TROUGH BY EARLY MORNING SUNDAY.  SFC LOW DEVELOPS TO THE EAST AT
THIS TIME CUTTING OFF THE DRYING DOWNSLOPE ALLOWING THE PRECIP
CHANCES TO SLIDE EASTWARD INTO THE PLAINS.  H5 VORT SHOULD KEEP THE
POPS GOING MOST OF SUNDAY...BUT THE NAM IS NOT BUYING INTO THE WET
SOLUTION YET.  GFS KEEPS POPS GOING ALL DAY SUNDAY FOR ALL ZONES.
GIVEN UNCERTAINTY...FORECAST METHOD TODAY WAS TO RAISE POPS
GENERALLY TO MAKE AN EVEN SPREAD AND NOT TRY TO PIN DOWN ANY ZONE.
OF GREATER CONCERN THIS FORECAST IS THE WIND. 700MB SPEEDS OF
60-70KTS ARE PROGGED BY ALL SHORT TERM MODELS IN VARIOUS PARTS OF
THE CWA AT VARIOUS TIMES.  IN A PERFECT WORLD...I WOULD ISSUE A
HIGH WIND WARNING FOR EVERYONE THROUGH MONDAY.  THIS WOULD BE ABSURD
OBVIOUSLY...SO THE PLAY WILL PROBABLY BE TO ISSUE A WIND WATCH FOR
THE HIGH ELEVATIONS AND LIMITED WY PLAINS SUCH AS PLATTE AND GOSHEN
COUNTIES DUE TO THE SW DIRECTION THAT IS NOT FAVORABLE FOR
CHEYENNE.  THIS DIRECTION IS FAVORABLE...HOWEVER...FOR THE RAWLINS
AND LARAMIE AREAS.  AFTER A BRIEF REPRIEVE THE WINDS WILL PICK UP
AGAIN IN A MORE TRADITIONAL WNW DIRECTION FAVORABLE FOR MOST OF THE
PLAINS...AND PROBABLY SLIDING INTO THE SOUTHERN PANHANDLE.

.LONG TERM...MONDAY THRU FRIDAY...SHORT UPPER RIDGE MOVES ACROSS THE
AREA MONDAY THEN NEXT UPPER TROF MOVES ACROSS MONDAY NIGHT AND
TUESDAY.  THIS SYSTEM SHOULD HAVE SIMILAR EFFECTS TO PREVIOUS SYSTEMS
BRINGING BEST SNOW TO THE MTNS WITH MORE SCTD SNOWSHOWERS OVER THE
ERN PLAINS ALONG WITH WINDY CONDITIONS.  SYSTEM PULLS AWAY TUESDAY
EVENING WITH A FEW LINGERING SNOWSHOWERS REMAINING OVER THE MTNS.
UPPER RIDGE THEN AMPLIFIES OVER THE WESTERN PART OF THE COUNTRY THRU
THE END OF THE WEEK WITH A DRIER NW FLOW SETTING UP ACROSS THE CWA.
TEMPS SLOWLY WARM THRU THE END OF THE WEEK WITH RIDGE MOVING ACROSS
THE CWA FRIDAY WHILE WEAKENING.
