AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
430 AM MDT FRI APR 13 2012

.SHORT TERM...TODAY THROUGH SUNDAY...
SOME SPRINKLES OR FLURRIES WILL CONTINUE OVER MUCH OF THE CWA
THROUGH MID MORNING AS A SHORTWAVE TROUGH CONTINUES TO LIFT
NORTHEAST OVER THE CWA.  THAT FEATURE WILL BE REPLACED BY A BRIEF
SHORTWAVE RIDGE OVER THE REGION FOR THE AFTERNOON.  SOME AFTERNOON
SHOWERS AND ISOLATED WEAK THUNDERSTORMS WILL BE POSSIBLE THIS
AFTERNOON OVER MAINLY THE WEST AND NORTH PARTS OF THE CWA.  THE
AIR MASS WILL CONTINUE TO BE FAIRLY MOIST AND SLIGHTLY UNSTABLE
DURING THAT TIME.  TEMPERATURES WILL BE A BIT COOLER THAN ON
THURSDAY...ESPECIALLY IN THE WESTERN AREAS.  SOME AREAS ALONG AND
WEST OF THE LARAMIE RANGE WILL ALSO RECEIVE WIND GUSTS AS HIGH AS
40 MPH TODAY.

THE REST OF THE FORECAST WILL BE CONTROLLED BY THE APPROACH AND
PASSAGE OF A STORM SYSTEM.  COOLER...WINDY AND WET WEATHER WILL
RESULT OVER THE CWA SATURDAY NIGHT AND SUNDAY.  THE BROAD UPPER LOW
WAS JUST MOVING INTO THE CENTRAL PART OF THE WEST COAST EARLY THIS
MORNING.  THAT FEATURE WILL DIG TO SOUTHERN NEVADA BY 12Z SATURDAY
AND THEN DEEPEN AS IT MOVES OVER NORTHEAST COLORADO 12Z SUNDAY.
00Z MODELS HAVE BEEN TRENDING SLIGHTLY FASTER WITH THE STORM SYSTEM
SATURDAY NIGHT AND SUNDAY WITH THE ECMWF STILL BEING THE SLOWEST
OF THE MODELS.  FOR NOW WILL LEAN TOWARD THE ECMWF AND GFS WHICH
HAVE BEEN MORE SIMILAR FOR THEIR 00Z RUNS.  SURFACE CYCLOGENESIS
TACKED PLACE OVER NORTHEAST COLORADO LATE TONIGHT AND SATURDAY AND
BECOMES VERTICALLY STACKED WITH THE UPPER LOW BY 12Z SUNDAY.  THE
ATMOSPHERE BECOMES NEARLY SATURATED SATURDAY NIGHT AND CONTINUES
FOR SUNDAY MORNING.  MUCH OF THE CWA WILL HAVE EXCELLENT SURFACE
FORCING...MID LEVEL CONVERGENCE AND A VERY DIFFLUENT FLOW AT 300
MB.  PRECIPITATION WILL INCREASE IN COVERAGE OVER THE CWA SATURDAY
WITH WIDESPREAD PRECIPITATION FOR SATURDAY NIGHT AND SUNDAY.  THE
MAIN CONCERN WILL CONTINUE TO BE WITH TEMPERATURES AND THE
RESULTING PRECIPITATION TYPE SATURDAY NIGHT AND SUNDAY.  AREAS OVER
AND WEST OF THE LARAMIE RANGE SHOULD CHANGE OVER TO ALL SNOW BY
SATURDAY EVENING.  A FOOT OR MORE OF SNOW IS LIKELY OVER THE SNOWY
AND SIERRA MADRE RANGES SATURDAY AND SATURDAY NIGHT AND HAVE ISSUED
A WINTER STORM WATCH FOR THAT TIME PERIOD.  THE LOWER ELEVATIONS
WILL RECEIVE 2 TO 5 INCHES OF SNOW MAINLY SATURDAY NIGHT AND
SUNDAY MORNING.  AN ADVISORY MAY BE NEEDED FOR THE LOWER ELEVATIONS
OF CARBON COUNTY.  FURTHER EAST...THE RAIN WILL CHANGE TO SNOW
SATURDAY EVENING AT ELEVATIONS ABOVE 5200 FEET MSL.  GUIDANCE
TEMPERATURES FOR SUNDAY AT ELEVATIONS BELOW 5200 FEET REMAIN IN THE
40S AND EVEN 50S..WITH THE ECMWF BEING THE COOLEST.  THE 700 MB
TEMPERATURES DO COOL TO MINUS 3C SUNDAY MORNING OVER THE PANHANDLE.
FOR NOW WILL ISSUE A WINTER STORM WATCH FOR 06Z TO 18Z SUNDAY FOR
THE AREA FROM K82V TO THE SNOWY RANGE.  AM NOT CONVINCED YET THAT
THE PANHANDLE WILL NOT SEE A MAJOR STORM AS DYNAMIC COOLING MAY
HELP CHANGE THE RAIN TO SNOW WITH LARGE ACCUMULATIONS POSSIBLE.
FOR NOW HAVE BETWEEN 0.5 AND 2 INCHES OVER THE PANHANDLE.  HAVE
KEPT TEMPERATURES COOLER THAN MODELS FOR SUNDAY.  THE OTHER ISSUE
WILL BE THE STRONG WINDS OVER MAINLY THE SOUTHEAST HALF OF THE
CWA SATURDAY NIGHT AND SUNDAY.  GUSTS BETWEEN 40 AND 50 MPH ARE
LIKELY AND WILL CREATE NEAR BLIZZARD CONDITIONS AT TIMES.  THE
WEATHER IMPROVES FROM WEST TO EAST SUNDAY AFTERNOON AS THE STORM
SYSTEM MOVES FURTHER EAST ONTO THE PLAINS.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...UPPER LEVEL TROUGH
AXIS WILL SHIFT EAST OF THE CWA SUNDAY NIGHT AND MONDAY...WITH
PROGRESSIVE NORTHWEST TO A MORE ZONAL FLOW PATTERN ALOFT TAKING
OVER. A WEAK SHORTWAVE WILL MOVE ACROSS WYOMING IN THIS FLOW
PATTERN SUNDAY NIGHT WITH A CHANCE FOR CONTINUED RAIN AND SNOW
SHOWERS THROUGH THE DAY ON MONDAY...ESPECIALLY COMING OFF THE
NORTHERN LARAMIE RANGE AND ACROSS THE PLAINS. STILL ONLY LOOKING
FOR HIGH TEMPS IN THE 50S ACROSS THE AREA AS THE THERMAL RIDGE IS
SLOW TO BUILD IN BEHIND THE SHORTWAVE TROUGH. YET ANOTHER
SHORTWAVE FEATURE WILL MOVE ACROSS THE NORTHERN ROCKIES ON TUESDAY
BRINGING ANOTHER ROUND OF SHOWERS TO THE AREA. SHOULD STAY MORE
RAIN ACROSS THE CWA WITH MAINLY HIGHER ELEVATION SNOWS ALONG WITH
BREEZY TO MODERATE WESTERLY WINDS AHEAD OF AND BEHIND A COLD FRONT
MOVING THROUGH THE AREA IN THE AFTERNOON AND EVENING. YET ANOTHER
WEAK WAVE LOOKS TO APPROACH FROM THE WEST LATER IN THE DAY ON
WEDNESDAY. WILL AGAIN SEE BREEZY TO MODERATE WESTERLY WINDS ALONG
WITH WARMING TEMPS FOR WEDNESDAY AFTERNOON. WILL BE DRY IN THE
MORNING WITH INCREASING CHANCES FOR PRECIP LATER IN THE DAY AS THE
SHORTWAVE APPROACHES FROM THE WEST. THIS SHORTWAVE TROUGH WILL
MOVE OVERHEAD ON THURSDAY WITH SLIGHT CHANCE TO CHANCE POPS FOR
RAIN AND HIGH ELEVATION SNOWS ONCE AGAIN EXPECTED THROUGH THE DAY.
LOOKS AS THOUGH WEAK NORTHWEST FLOW RETURNS FOR FRIDAY KEEPING
THINGS COOLER AND DRIER ACROSS THE CWA.

&&

.AVIATION...06Z ISSUANCE...SHOWERS OVER NORTHEAST COLORADO IN
ASSOCIATION WITH AN UPPER LEVEL DISTURBANCE WILL SHIFT EAST
OVERNIGHT. A FEW LIGHT SHOWERS ARE POSSIBLE NEAR SIDNEY THROUGH
09Z BUT VISIBILITIES SHOULD REMAIN VFR. MVFR TO IFR POSSIBLE
MAINLY FROM THE LARAMIE RANGE WEST TONIGHT AS A SEPARATE WEAK
UPPER LEVEL DISTURBANCE MOVES ACROSS THAT AREA. MAINLY LOOKING AS
ISOLATED TO SCATTERED SNOW SHOWERS REDUCING VISIBILITIES.
OTHERWISE MAINLY VFR THROUGH TOMORROW AFTERNOON THEN INCREASING
CLOUDS WITH LOWERING CIGS. STRONG AREA OF LOW PRESSURE EXPECTED TO
MOVE ACROSS THE CENTRAL ROCKIES LATE SATURDAY AND SUNDAY PRODUCING
WIDESPREAD SNOW AND STRONG WINDS.

&&

.FIRE WEATHER...FIRE WEATHER CONCERNS WILL BE MINIMAL THROUGH
EARLY NEXT WEEK. THE PACIFIC STORM SYSTEM WILL PRODUCE COOLER
AND WETTER WEATHER OVER THE CWA...ESPECIALLY SATURDAY NIGHT AND
SUNDAY. SIGNIFICANT RAIN OR SNOW IS LIKELY DURING THAT TIME.
NORTHERLY SURFACE WINDS WILL GUST AS HIGH AS 50 MPH AS WELL
SATURDAY NIGHT AND SUNDAY. WARMER AND DRIER WEATHER RETURN TO THE
REGION STARTING ON TUESDAY AND CONTINUING THROUGH THE MID PART OF
NEXT WEEK.
