INCHES OF SNOW WERE REPORTED ACROSS THE LOWER ELEVATIONS OF
CARBON/ALBANY COUNTIES. HAHN

.PREV DISCUSSION... /ISSUED 409 AM MST WED NOV 24 2010/

SHORT TERM...TODAY THROUGH FRIDAY NIGHT
SATELLITE CONTINUES TO SHOW THAT THE STORM SYSTEM IS RAPIDLY MOVING
ACROSS CARBON COUNTY. SNOWFALL AMOUNTS HAVE NOT BEEN THAT
IMPRESSIVE ACROSS MOST OF CARBON COUNTY...THEREFORE AM
CONTEMPLATING DROPPING THE WINTER STORM WARNING FOR THE SOUTHERN
TWO THIRDS OF CARBON COUNTY AND JUST GO WITH A WINTER WEATHER
ADVISORY. FOR PLACE THAT HAVE THE WINTER WEATHER ADVISORY...WILL
JUST DROP ALL TOGETHER. WINDY CONDITIONS WILL OCCUR ACROSS THE
FORECAST AREA TODAY...SO TEMPERATURES WILL FEEL EVEN COLDER. THE
WINDS WILL ALSO CREATE AREAS OF BLOWING SNOW AND REDUCED
VISIBILITIES ACROSS CARBON COUNTY.  CYCLONIC FLOW WILL BE ALOFT
TODAY AS THE MAIN UPPER LOW MOVES ACROSS MT. VERY COLD
TEMPERATURES WILL OCCUR TODAY AS A VERY COLD SURFACE HIGH BUILDS
IN BEHIND THE COLD FRONT WHICH IS ABOUT TO GO THE CYS AT THIS
TIME. THE COLD FRONT SHOULD BE EAST OF THE CWA EARLY THIS MORNING.
LIGHT SNOW WILL FALL IN THE SOUTHERN MOUNTAINS...WITH ADDITIONAL
ACCUMULATIONS OF 2 TO 3 INCHES BY EVENING. LIGHT SNOW WILL OCCUR
ACROSS THE LOWER ELEVATIONS OF THE CWA THIS MORNING...BUT
ACCUMULATIONS WILL ONLY BE AN INCH OR LESS. THE SNOW WILL LINGER
IN THE MOUNTAINS THIS AFTERNOON BUT WILL END ACROSS THE REST OF
THE AREA. VERY COLD WIND CHILLS WILL OCCUR ACROSS MUCH OF THE AREA
TONIGHT...ESPECIALLY IN AND WEST OF THE LARAMIE RANGE AND ACROSS
THE NORTHERN ZONES. A WIND CHILL WARNING OR ADVISORY WILL LIKELY
BE NEEDED FOR THIS AREA. THE UPPER LOW WILL MOVE ACROSS THE
NORTHERN PLAINS TONIGHT WITH THE AXIS EAST OF THE CWA BY 12Z THUR.
A SLIGHT CHANCE OF SNOW CAN BE EXPECTED IN THE SOUTHERN MOUNTAINS
TONIGHT...BUT DRY CONDITIONS WILL PREVAIL ACROSS THE REST OF THE
AREA.  VERY WINDY CONDITIONS WILL OCCUR ONCE AGAIN ON THANKSGIVING
DAY...AND A HIGH WIND WARNING WILL LIKELY BE NEEDED FOR THE MOUNTAINS.
WILL DEFER TO DAY SHIFT TO AVOID CONFUSION WITH THE CURRENT AND UPCOMING
HIGHLIGHTS EXPECTED FOR TONIGHT. TEMPERATURES WILL RECOVER
SOMEWHAT ON THANKSGIVING AND WILL NOT BE AS COLD AS TODAY. THE NW
FLOW WILL CONT ALOFT ON FRI AND WARMER TEMPERATURES WILL OCCUR
ACROSS THE AREA AS AN UPPER RIDGE MOVES OVER THE WESTERN U.S. THE
UPPER RIDGE AXIS WILL BEGIN TO MOVE INTO THE WESTERN PORTION OF
THE CWA FRI NIGHT. TEMPERATURES THIS AFTERNOON WILL BE AT LEAST 20
DEGREES BELOW NORMAL. HIGH TEMPERATURES ON FRI WILL BE AROUND 15
DEGREES BELOW NORMAL AND 5 TO 10 DEGREES BELOW NORMAL ON SAT.

LONG TERM...SATURDAY THROUGH WEDNESDAY...
LOW AMPLITUDE MID/UPPER-LEVEL RIDGING WILL BE IN PLACE ACROSS THE
NORTHERN ROCKIES TO BEGIN THE PERIOD. THIS WILL YIELD DRY CONDITIONS
AND NEARLY SEASONAL TEMPERATURES ACROSS THE CWA FOR SATURDAY AND
SATURDAY NIGHT. MEDIUM RANGE GUIDANCE IS CONSISTENT IN SWINGING THE
NEXT UPPER SHORTWAVE AND ASSOCIATED COLD FRONT THROUGH SOUTHEAST
WYOMING AND THE WESTERN NEBRASKA PANHANDLE DURING THE DAY ON SUNDAY.
SO...SNOW CHANCES WILL BE ON THE INCREASE FOR AREAS WEST OF THE
LARAMIE RANGE DURING THE DAY ON SUNDAY...AND OUT ONTO THE EASTERN
PLAINS SUNDAY NIGHT. MODEL DIFFERENCES BEGIN TO EMERGE FOR SUNDAY
NIGHT THROUGH THE MIDDLE OF NEXT WEEK. BOTH THE 00Z GFS/GEM CLOSE
THIS SHORTWAVE OFF OVR THE CENTRAL HIGH PLAINS LATE MONDAY
NIGHT...WHILE THE 00Z ECMWF IS MUCH SLOWER AND DEEPER WITH THE
SYSTEM TRACKING IT ACROSS SRN COLORADO AND INTO THE SOUTHERN PLAINS
ON MONDAY. GENERALLY FOLLOWED THE QUICKER SOLUTION OF THE GFS/GEM
FOR THIS FORECAST. DOESNT LOOK LIKE A SIGNIFICANT EVENT WITH THIS
SYSTEM...BUT AN EVENTUALLY A HIGH POP/LOW SNOW ACCUM EVENT WILL BE
POSSIBLE. HIGH TEMPERATURES ON SUNDAY WILL BE HEAVILY RELIANT UPON
THE TIMING OF THE COLD FROPA...BUT SOME COOLING CAN BE EXPECTED.
POST-FRONTAL NORTHERLY WINDS OF 20 TO 30 MPH WITH GUSTS TO 40 MPH
WILL COMBINE WITH HIGH TEMPERATURES ONLY REACHING THE 20S TO MAKE
MONDAY A RATHER BLUSTERY DAY. THE MEDIUM RANGE DIFFERENCES CONTINUE
FOR TUESDAY AND WEDNESDAY...WITH THE 00Z GFS/GEM/GEFS MAINTAINING
DRY NORTHWEST FLOW...WHILE THE 00Z ECMWF DROPS ANOTHER SHORTWAVE
SOUTHEAST INTO THE NRN PLAINS. AGAIN...GIVEN THE RELATIVE RUN-TO-RUN
INCONSISTENCY EVIDENT IN THE ECMWF...FAVORED THE DRIER SOLUTION FOR
THIS PERIOD. TEMPERATURES WILL MODERATE BACK INTO THE 30S FOR
TUESDAY...AND EVEN LOW TO MID 40S OUT ON THE EASTERN PLAINS FOR
WEDNESDAY.
