AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
409 AM MST THU FEB 17 2011
.SHORT TERM...TODAY THROUGH SATURDAY...CURRENT OBS ACROSS
SOUTHEAST WYOMING SHOW A VIGOROUS PACIFIC COLD FRONT PUSHING
ACROSS THE REGION RESULTING IN HEAVY MOUNTAIN SNOWS AND VERY
STRONG WINDS AT THE SURFACE. HAVE HAD REPORTS OF WIND GUSTS AROUND
68 MPH IN CONVERSE AND CARBON COUNTIES EARLY THIS MORNING AS THE
FRONT IS CURRENTLY FROM JUST SOUTH OF LARAMIE EXTENDING NORTHEAST
ACROSS GOSHEN AND PLATTE COUNTIES. WILL KEEP THE HIGH WIND WARNING
OUT FOR ALL OF SOUTHEAST WYOMING THIS MORNING...EVEN THOUGH WINDS
SHOULD BEGIN TO SUBSIDE ACROSS CARBON AND ALBANY COUNTIES.
EXTENDED THE HIGH WIND WARNING FOR THE FAR EASTERN WYOMING HIGH
PLAINS ZONES INTO THIS AFTERNOON WITH MOS SHOWING THE STRONGEST
WINDS STARTING LATER THAN THE ZONES FURTHER TO THE WEST. ISSUED A
WIND ADVISORY FOR WESTERN NEBRASKA EARLIER THIS MORNING WITH GUSTY
WINDS EXPECTED...MAY NEED TO UPGRADE THIS TO A HIGH WIND WARNING
MAINLY FOR SUSTAINED WINDS...BUT DO NOT EXPECT THE HIGHER GUSTS AT
THIS TIME. OTHERWISE...WINTER WEATHER HEADLINES LOOK ON TRACK FOR
THE SNOWY RANGE AND SIERRA MADRE RANGE FOR LOCALLY HEAVY SNOWFALL
TODAY. IN THE LOWER VALLEYS OF CARBON AND ALBANY COUNTIES...EXPECT
UP TO 1 INCH OF SNOW THAT WILL LIKELY MELT QUICKLY DURING THE DAY
TODAY.
MODELS IN GOOD AGREEMENT THROUGH THE SHORT TERM...SHOWING THE
FIRST FRONT...CURRENTLY MOVING ACROSS THE AREA THIS
MORNING...PUSHING NORTHEASTWARD AS THE QUICKLY MOVING UPPER LEVEL
TROUGH PUSHES INTO THE NORTHERN PLAINS BY LATE TODAY. SOUTHWEST
FLOW ALOFT WILL CONTINUE ACROSS THE AREA THROUGH FRIDAY AS A
STRONGER STORM SYSTEM PUSHES INTO THE WEST COAST FRIDAY AND FRIDAY
NIGHT. WARMER THAN NORMAL TEMPERATURES ARE EXPECTED TO CONTINUE
AFTER A BRIEF COOL DOWN TODAY...WITH HIGHS RETURNING TO THE 50S
OVER THE HIGH PLAINS ON FRIDAY. LOW TEMPS WILL REMAIN SEASONABLY
COOL AND GENERALLY IN THE 20S...WITH TEENS AND SINGLE DIGITS WEST
OF THE LARAMIE RANGE. DRY WEATHER IS EXPECTED WITH POP BELOW 10
PCT...EXCEPT FOR THE MOUNTAINS WHICH MAY RECEIVE SOME SNOW SHOWER
ACTIVITY AT TIMES EARLY FRIDAY MORNING AND AGAIN FRIDAY NIGHT
AHEAD OF THE NEXT STORM SYSTEM. BY SATURDAY...ALL MODELS SHOW THIS
STORM SYSTEM PUSHING ONSHORE AS A STRONG NEGATIVELY TILTED UPPER
LEVEL TROUGH MOVES INTO THE GREAT BASIN REGION. EXPECT SNOW...WITH
A MIX OF RAIN IN THE VALLEYS BELOW 7500 FEET...TO DEVELOP ALONG
AND WEST OF THE LARAMIE RANGE. WINDS ARE NOT EXPECTED TO BE MUCH
OF AN ISSUE WITH THIS STORM...AS AN ARCTIC HIGH PUSHES SOUTHWARD
INTO THE NORTHERN PLAINS RESULTING IN EAST TO SOUTHEAST WINDS
ACROSS THE AREA AS A SURFACE LOW MOVES ACROSS COLORADO AND
REDEVELOPS IN THE LEE OF THE ROCKIES. INCREASED POP ALONG AND WEST
OF THE LARAMIE RANGE SATURDAY WITH SNOWFALL LIKELY IN THE
MOUNTAINS.
.LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY...
MODELS ARE GRADUALLY BECOMING MORE SIMILAR LATE THIS WEEKEND AND
EARLY NEXT WEEK WITH THE NEXT WIDESPREAD PRECIPITATION EVENT. AT 00Z
SUNDAY...A CLOSED UPPER LOW IS OVER OR JUST OFF THE CENTRAL CALIFORNIA
COAST. THE FEATURE IS PUSHED EAST BY THE NEXT UPSTREAM SYSTEM FAIRLY
QUICKLY AND FILLS AT IT MOVES OVER THE CENTRAL ROCKIES. THE
SHORTWAVE TROUGH IS EAST OF THE CWA MONDAY AFTERNOON. THE 00Z GFS IS
TRENDING SLOWER WHILE THE 00Z ECMWF IS TRENDING A BIT FASTER WITH
THE MOVEMENT OF THE SHORTWAVE TROUGH. A COLD FRONT MOVES ACROSS THE
CWA LATE SATURDAY AFTERNOON AND EARLY SATURDAY NIGHT. BRISK NORTH
OR NORTHEAST SURFACE WINDS AND COLDER TEMPERATURES WILL BE BEHIND THE
FRONT WITH THE COLD TEMPERATURES LINGERING THROUGH MONDAY. OVER THE
COLDER AIR...THE SHORTWAVE TROUGH AND THE CYCLONIC SIDE OF THE
ASSOCIATED 300 MB JET WILL PROVIDE SYNOPTIC LIFT FOR SATURDAY NIGHT
THROUGH SUNDAY NIGHT. THE SURFACE UPSLOPE WEAKENS MONDAY AS THE
SURFACE HIGH BUILDS OVER THE PLAINS. FOR NOW WILL INCREASE POPS
QUITE A BIT AND LOWER TEMPERATURES FOR THE CWA SATURDAY NIGHT THROUGH
SUNDAY NIGHT. ACCUMULATING SNOW IS LIKELY...WITH ADVISORY AMOUNTS
POSSIBLE IN SOME LOCATIONS...WITH 00Z MODELS POINTING TO THE NORTH
PART OF THE CWA AND THE MOUNTAINS. THE PRECIPITATION TYPE AT LEAST
INITIALLY MAY START OUT AS RAIN OVER SOME OF THE LOWER ELEVATIONS...
BUT THEN BECOME ALL SNOW SOON AFTER. THE CWA WILL BE BETWEEN WEATHER
SYSTEMS THEN FOR TUESDAY AND WEDNESDAY BEFORE THE NEXT STORM AFFECTS
THE CWA ON NEXT THURSDAY. WITH THE WESTERLY FLOW ALOFT INCREASING ON
THOSE DAYS...IT WILL BE A WINDY PERIOD IN AREAS ALONG AND WEST OF THE
LARAMIE RANGE. THE ECMWF CONTINUES TO BE SLOWER THAN THE GFS FOR THE
MID PART OF THE WEEK AND IS PREFERRED BY HPC. HOWEVER...EVEN THE 00Z
ECMWF MOVES ANOTHER SURGE OF COLDER AIR ACROSS THE CWA LATE WEDNESDAY
NIGHT AND THURSDAY. PATTERN IN MANY WAYS LOOKS SIMILAR TO THIS
WEEKENDS EVENT AND SO WILL TREND POPS UP AND TEMPERATURES DOWN.&&
