AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
243 AM MST SAT NOV 12 2005

.SHORT TERM...TODAY THROUGH SUNDAY...UPPER LOW IS CURRENTLY TRACKING
OVER NORTHEASTERN CO AS EVIDENCED BY WATER VAPOR AND INFRARED
SATELLITE IMAGERY. AREA RADARS SHOW PRECIPITATION OVER MUCH OF THE
FORECAST AREA WITH PRECIP ENDING OVER WESTERN CARBON COUNTY IN SOUTH
CENTRAL WY. PRECIP WILL DIMINISH FROM WEST TO EAST THIS MORNING AS
THE UPPER LOW AND ASSOCIATED SURFACE LOW MOVE AWAY FROM THE FORECAST
AREA. THE FORECAST ISSUE THEN BECOMES THE WIND AS THE SURFACE LOW
DEEPENS OVER NEB THIS MORNING WHILE SURFACE HIGH PRESSURE ADVECTS
TOWARD WESTERN WY. AN UPPER LEVEL SPEED MAX WILL PUSH THROUGH THE
REGION THIS MORNING WITH GOOD DIRECTIONAL ALIGNMENT BETWEEN
NORTHWESTERLY SURFACE WINDS AND THE FAST NORTHWESTERLY FLOW ALOFT.
ADDITIONALLY...LOW LEVEL COLD AIR ADVECTION WILL ASSIST IN DOWNWARD
MOMENTUM OF WINDS. WINDS SHOULD REMAIN SOMEWHAT BELOW HIGH WIND
WARNING CRITERIA THIS AFTERNOON IN THE AREA...BUT WILL ISSUE A WIND
ADVISORY FOR THE NEB PANHANDLE PORTION OF THE FORECAST AREA FROM
LATE MORNING THROUGH THIS AFTERNOON. LOWER LEVELS OF THE AIRMASS
WILL DRY FROM WEST TO EAST TODAY. WILL KEEP MENTION OF POSSIBLE
SHOWERS TODAY OVER THE MOUNTAINS AND OVER EASTERN PORTIONS OF THE
FORECAST AREA...WITH RAIN EAST OF THE MOUNTAINS AND PRIMARILY SNOW
IN THE MOUNTAINS. TODAY WILL BE COOLER BUT STILL ABOVE NORMAL. TEMPS
WILL REACH THE 50S EAST OF THE MOUNTAINS WITH MAINLY 40S IN THE
LARAMIE VALLEY AND CARBON COUNTY...AND 30S IN THE HIGHEST MOUNTAINS.
SURFACE WINDS WILL DECREASE LATE THIS AFTERNOON AS THE ATMOSPHERE
DECOUPLES AROUND SUNSET...ALTHOUGH BREEZY AREAS WILL EXIST
OVERNIGHT. TONIGHT WILL BE DRY AND COLDER WITH TEMPS DIPPING INTO
THE 20S OUTSIDE THE MOUNTAINS. LOW LEVEL LEESIDE TROUGHING WILL
DEVELOP OVER WY SUNDAY AND WILL PRODUCE AREAS OF BRISK WINDS MAINLY
FROM THE LARAMIE RANGE WESTWARD. TEMPS SUN WILL BE A BIT COOLER WITH
A FEW OROGRAPHIC SNOW SHOWERS POSSIBLE IN THE HIGHEST MOUNTAINS.

.LONG TERM...THE FAST MOVING SHORTWAVE TROUGH AND ASSOCIATED SURFACE
COLD FRONT ARE STILL EXPECTED TO AFFECT THE CWA MONDAY AND MONDAY
NIGHT.  PRIOR TO THAT TIME...WINDS ALOFT INCREASE OVER THE CWA IN
ADVANCE OF THE APPROACHING SYSTEM FROM WESTERN CANADA.  THE FORECAST
700 MB KCAG TO KCPR HEIGHT DIFFERENCE IS 70 TO 90 METERS SUNDAY
NIGHT AND INTO MONDAY MORNING.  A HIGH WIND WATCH WILL LIKELY BE
NEEDED DURING THAT TIME FOR MUCH OF THE WYOMING PART OF THE CWA.
MOUNTAIN SNOW WILL ALSO PICK UP SUNDAY NIGHT AND MONDAY MORNING AS
THE MOIST...OROGRAPHIC WIND FLOW INCREASES.  SIGNIFICANT SHORTWAVE
WILL MOVE OVER THE NORTHERN AND CENTRAL ROCKIES AND NORTHERN PLAINS
MONDAY AND TUESDAY.  MOST OF THE ENERGY MOVES FROM EASTERN MONTANA
18Z MONDAY TO SOUTHERN MINNESOTA AND NORTHERN IOWA 12Z TUESDAY.
MODELS ARE NOW FAIRLY CLOSE WITH THE MOVEMENT OF THE SHORTWAVE
TROUGH.  THE ASSOCIATED SURFACE COLD FRONT MOVES RAPIDLY ACROSS THE
CWA FROM MID MORNING MONDAY TO MID AFTERNOON MONDAY.  STRONG COLD
AIR ADVECTION...LARGE SURFACE PRESSURE RISES AND STRONG WINDS AT 700
MB WILL MAKE FOR A COOL AND WINDY PERIOD BEHIND THE FRONT MONDAY
AFTERNOON AND EARLY MONDAY NIGHT.  IN ADDITION...FOR A 3 TO 6 HOUR
PERIOD BEHIND THE FRONT THERE WILL BE GOOD SYNOPTIC LIFT...MID LEVEL
FRONTOGENESIS AND A NORTHERLY COMPONENT TO THE BOUNDARY LAYER WIND.
HIGH POPS FROM LIGHT SNOW STILL ON TRACK FOR MAINLY MONDAY AFTERNOON
AND EARLY MONDAY NIGHT.  THE SNOW WILL TAPER OFF AND END FROM NORTH
TO SOUTH LATER MONDAY NIGHT AND EARLY TUESDAY MORNING.  MODELS ARE
IN GENERAL AGREEMENT WITH THAT SCENARIO.  IN GENERAL...1 TO 3 INCHES
OF SNOW WILL BE COMMON OVER THE LOWER ELEVATIONS OF THE CWA...WITH
SOME PLACES GETTING UP TO 5 INCHES.  ANOTHER CLIPPER TYPE SYSTEM
WILL MOVE A SHALLOW COLD FRONT ACROSS THE EAST PART OF THE CWA ON
THURSDAY...WITH MOST OF THE ENERGY FURTHER EAST THAN THE SYSTEM FOR
MONDAY AND MONDAY NIGHT.  AFTER A COOL DAY ON TUESDAY...THE
TEMPERATURES WILL BE AT OR ABOVE NORMAL FOR WEDNESDAY THROUGH
SATURDAY AS HEIGHTS ALOFT RISE. THE EXCEPTION MAY POSSIBLY BE ON
THURSDAY IN THE EAST PART OF THE CWA BEHIND THE FRONT.  WILL KEEP
THE FORECAST DRY AS WELL FOR THAT TIME PERIOD.
