AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
400 AM MST THU JAN 11 2007

.SHORT TERM...ADVERTISED BIG CHANGE IN THE WEATHER STILL LOOKS TO BE
ON TRACK FOR THE REGION.  MUCH COLDER WEATHER ALONG WITH GENERALLY
LIGHT SNOW WILL BE OVER MUCH OF THE CWA LATER TODAY AND THROUGH
FRIDAY NIGHT.  THE DEVELOPING UPER LOW WAS OVER THE PACIFIC NORTHWEST
EARLY THIS MORNING AND WILL DIG SOUTH AND BY FRIDAY AFTERNOON WILL BE
OVER THE GREAT BASIN.  THE FEATURE THEN MOVES SLOWLY EAST THROUGH 12Z
SATURDAY.  00Z MODELS NOW ARE MORE SIMILAR IN THEIR TIMING AND TRACK
OF THE UPPER LOW.  THE SHALLOW SURFACE COLD FRONT HAS ALREADY MOVED
THROUGH MUCH OF THE CWA AS OF 10Z WITH THE EXCEPTION OF SOUTH OF A
KCYS TO KRWL LINE.  THE FRONT SHOULD MOVE THROUGH THE REST OF THE
CWA DURING THE MORNING HOURS AND WILL BE SLOWER TO MOVE SOUTHWEST
DUE ITS SHALLOW NATURE.  LOW CLOUDS LAG THE FRONTAL PASSAGE BY 4 TO
6 HOURS AND THE PRECIPITATION EVEN MORE.  AS OF 1030Z THE MORE
WIDESPREAD SNOW WAS OVER NATRONA COUNTY AND AREAS NORTH.  TEMPERATURES
TODAY WILL BE NEARLY STEADY OR EVEN FALLING BEHIND THE FRONT AND
THEN FALL LATER IN THE DAY IN CURRENT AREAS AHEAD OF THE FRONT.  THE
CHILLY TEMPERATURES HAVE BEEN A GIVEN FOR THE CWA FOR ESPECIALLY
TONIGHT THROUGH FRIDAY NIGHT.  GUIDANCE HAS EVEN TRENDED COLDER THE
PAST FEW RUNS.  THE MAIN QUESTION IS SNOW AMOUNTS OVER MUCH OF THE
CWA AS WELL AS PRECIPITATION TYPE OVER THE EAST PART OF THE CWA.
SYNOPTIC PATTERN IS FAVORABLE FOR THE LONG DURATION LIGHT SNOW EVENT
AS THE 300 MB JET RIDES OVER THE SHALLOW ARCTIC BOUNDARY. BEST
FORCING AND DEEPER MOISTURE STILL APPEARS TO BE IN THE AREA FROM
CARBON COUNTY TO CONVERSE COUNTY.  MODELS HAVE BEEN CONSISTENT ON
THEIR QPF AND HPC GUIDANCE HAS AS MUCH AS 6 TO 12 INCHES OF SNOW
OVER THAT AREA FROM LATER TODAY THROUGH 12Z SATURDAY.  WILL GO AHEAD
AND ISSUE A SNOW ADVISORY FOR CARBON TO CONVERSE COUNTIES FOR TONIGHT
THROUGH MIDNIGHT FRIDAY NIGHT.  THE SNOW WILL BECOME LIGHTER FURTHER
EAST IN THE CWA AS THE BOUNDARY LAYER REMAINS QUITE SHALLOW AND NOT
AS MOIST AIR SEEMS TO BE OVER THE ARCTIC AIR MASS.  FORECAST RAOBS
INDICATE THE POSSIBILITY OF FREEZING DRIZZLE OVER THE NORTHEAST PART
OF THE CWA TODAY AND SHIFTING TO THE SOUTHERN NEBRASKA PANHANDLE BY
TONIGHT.

.LONG TERM...SATURDAY THROUGH WED. COLD AND UNSETTLED WEATHER WILL
CONTINUE INTO NEXT WEEK. A BROAD AND DEEP UPPER TROUGH WILL REMAIN
OVER THE FORECAST AREA AS ENERGY PERIODICALLY MOVES THROUGH THE
TROUGH. THE MODELS VARY ON THE DETAILS SO IT MAKES SENSE TO FORECAST
RATHER CONSERVATIVELY AT THIS POINT UNTIL THE PICTURE BECOMES MORE
CLEAR. THE TROUGH WILL FINALLY MOVE OFF TO THE EAST TUE AS DRIER
NORTHWESTERLY FLOW ALOFT DEVELOPS OVER THE FORECAST AREA.
NORTHWESTERLY UPPER FLOW WILL CONTINUE WED. COLD AND MOIST SURFACE
BASED UPSLOPE FLOW WILL CONTINUE SAT AS SURFACE LOW PRESSURE MOVES
TO OUR SOUTH WITH ARCTIC HIGH PRESSURE OVER THE NORTHERN PLAINS.
SUNDAY WILL REMAIN QUITE COLD WITH SNOW A CONTINUING POSSIBILITY.
THE AIRMASS WILL DRY MON UNDER THE INFLUENCE OF SURFACE HIGH
PRESSURE...ALTHOUGH TEMPS WILL REMAIN VERY CHILLY. DRY LOW LEVEL
DOWNSLOPE FLOW WILL INITIATE A MODEST WARMING TREND TUE. WED WILL
REMAIN DRY WITH TEMPERATURES CONTINUING TO MODERATE...ALTHOUGH TEMPS
WILL STILL BE BELOW NORMAL.

&&

.AVIATION...IFR CEILINGS AND VISIBILITIES WILL SPREAD INTO OR DEVELOP
OVER MOST LOCATIONS IN THE CWA THROUGH EARLY TONIGHT BEHIND THE COLD
FRONT.  THE VISIBILITIES WILL BE REDUCED BY MAINLY LIGHT SNOW...WITH
FREEZING DRIZZLE A POSSIBILITY MAINLY NORTH OF A KLSK TO KAIA LINE
TODAY AND THEN SHIFTING TO MAINLY THE SOUTHERN NEBRASKA PANHANDLE
TONIGHT.  NEEDLESS TO SAY...ICING WILL BE A CONCERN OVER MUCH OF THE
CWA LATER TODAY AND TONIGHT...ESPECIALLY IN THE WESTERN NEBRASKA
PANHANDLE.  TURBULENCE CAN ALSO BE EXPECTED NEAR THE TOP OF THE
BOUNDARY LAYER WHICH WILL VARY FROM 10 THOUSAND FEET MSL IN THE
NORTH PART OF THE CWA TO 5 TO 7 THOUSAND FEET MSL IN SOUTHERN
SECTIONS.
