138 PM MST FRI NOV 30 2007

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...
QUITE A COMPLICATED FCST WRT UPPER SYSTEM THAT WILL BE MOVING ACROSS
THE REGION OVER THE NEXT 36 HOURS.  MOIST SW FLOW PRESENT OVER THE
CWA NOW WITH ECHOS ON RADAR BECOMING MORE PERSISTANT OVER THE SRN
MTNS.  WITH PLENTY OF MOISTURE STILL TO COME WILL UPGRADE WINTER
STORM WATCH TO WARNING FOR THE SNOWY/SIERRA MADRE RANGES FOR TONIGHT
THROUGH MOST OF SATURDAY AS AMOUNTS AROUND A FOOT QUITE LIKELY THERE
BEFORE TAPERING OFF SATURDAY EVENING.  SNOW SHOULD HOLD OFF OVER THE
REST OF SE WY UNTIL LATER TONIGHT WHEN MAIN SHOT OF VORT ENERGY WILL
APPROACH THE CWA AND LIFT INCREASES. DECENT BAND OF SNOW SHOULD LIFT
NORTH ACROSS THE CWA SAT MORNING WITH BEST SNOWFALL AMOUNTS APPEARING
TO TARGET WRN AND NRN PARTS MAINLY SAT MORNING INTO THE AFTN.  WILL
ALSO HOIST A SNOW ADVY IN THESE AREAS FOR SAT.  OTHER PROBLEM IS
LIKELYHOOD FOR SOME FREEZING PCPN TO FALL FOR A SHORT TIME LATER
TONIGHT INTO EARLY SAT ACROSS THE SE PART OF THE PANHANDLE AS
SOUNDINGS INDICATE SUFFICIENTLY WARM LAYER OVER SUBFREEZING SFC.
RATHER NARROW WINDOW OF OPPORTUNITY HERE SHOULD LIMIT AMOUNT OF ANY
ICING BUT ENOUGH THAT I WILL ISSUE WINTER WX ADVY FOR A COUPLE OF
COUNTIES.  OVER THE NORTHERN PANHANDLE SOUNDINGS INDICATE CAA WILL
COOL LOWER LAYERS BELOW FREEZING BEFORE BULK OF PCPN ARRIVES SO
EXPECT LITTLE IF ANY FREEZING PCPN THERE AT THIS TIME.  CONDITIONS
WILL IMPROVE SAT EVENING AS SFC LOW MOVES EAST AND UPPER TROF PASSES
ACROSS.

.LONG TERM...SUNDAY THROUGH FRIDAY...
FLURRIES OR LIGHT SNOW WILL LINGER OVER THE CWA SUNDAY MORNING BEFORE
THE SHORTWAVE TROUGH MOVES ONTO THE PLAINS AND THE SURFACE UPSLOPE
WEAKENS.  WILL ALSO KEEP SOME LIGHT SNOW CONTINUING ALL DAY SUNDAY
OVER THE SNOWY RANGE DUE TO THE OROGRAPHIC WIND FLOW.  MODELS ARE
THEN SIMILAR THROUGH TUESDAY WITH RISING HEIGHTS ALOFT OVER THE
ROCKIES AND A BROAD RIDGE ALOFT OVER MUCH OF THE WESTERN PART OF THE
NATION.  DURING THE SAME TIME...A SURFACE LOW PRESSURE TROUGH WILL
DEVELOP OVER THE HIGH PLAINS.  THOSE FEATURES WILL COMBINE TO PRODUCE
ABOVE NORMAL TEMPERATURES AND DRY AND WINDY WEATHER FOR THE CWA ON
MONDAY AND TUESDAY.  MODELS DIFFER SOME FOR THE REMAINDER OF NEXT
WEEK BUT BOTH THE 12Z GFS AND 00Z CANADIAN ARE MORE SIMILAR NOW TO THE
00Z ECMWF.  THE GENERAL CONSENSUS ON THOSE MODELS AND THE GFS
ENSEMBLE MEMBERS IS FOR SHORTWAVE TROUGHS TO MOVE ACROSS THE CENTRAL
ROCKIES IN THE NORTHWEST FLOW ALOFT WEDNESDAY NIGHT AND AGAIN FOR
NEXT FRIDAY.  A COLD FRONT WILL ALSO BACK INTO AT LEAST THE EAST
PART OF THE CWA TUESDAY NIGHT AND WEDNESDAY MORNING.  WILL PLACE
LOW POPS ALONG AND BEHIND THE FRONT ON WEDNESDAY AS WELL AS COOL
TEMPERATURES.  THE BOUNDARY LAYER UPSLOPE WIND FLOW PERSISTS THROUGH
NEXT FRIDAY AND IS REINFORCED BY CYCLOGENESIS WEDNESDAY NIGHT AND
FRIDAY OVER COLORADO IN RESPONSE TO THE SHORTWAVE TROUGHS.  HAVE
INCREASED POPS AND CLOUDS SOME FOR THOSE PERIODS.  THE 12Z GFS AND
00Z ECMWF INDICATE ACCUMULATIONS OF SNOW WEDNESDAY NIGHT AND AGAIN ON
FRIDAY.

&&

.AVIATION...MOSTLY VFR CONDS EARLY THIS EVENING WILL DETERIORATE TO
WIDESPREAD MVFR/IFR CONDS LATER TONIGHT DUE TO LOW CIGS AND PCPN AS
SFC UPSLOPE FLOW INCREASES AND UPPER TROF APPROACHES FROM THE SW.
SOME FREEZING PCPN EXPECTED PRIMARILY OVER THE SRN NEB PANHANDLE
LATER TONIGHT INTO SAT MORNING.  SOME IMPVMNT OVER SRN SECTIONS SAT
