AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
509 AM MST FRI FEB 14 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 509 AM MST FRI FEB 14 2014

CURRENT RADAR LOOP SHOWS THE BAND OF SNOW HAS WEAKENED AND MOVED
SOUTH INTO COLORADO EARLY THIS MORNING. BASED OFF REPORTS FROM
DISPATCH AND A QUICK LOOK AT WEBCAMS...RECEIVED AN AVERAGE OF 1 TO 3
INCHES OF ACCUMULATION OVERNIGHT ACROSS MUCH OF THE PLAINS...WITH
POSSIBLY A FEW LOCALLY HIGHER AMOUNTS UNDER THE HEAVIER SHOWERS IN
SCOTTS BLUFF AND EASTERN LARAMIE/KIMBALL COUNTIES. WATER VAPOR
IMAGERY INDICATES THE VERY STRONG JET CORE OVERHEAD NOW...AND
STEADILY SHIFTING TO THE EAST WITH DRIER AIR AND SUBSIDENCE MOVING
OVERHEAD IN ITS WAKE.

WINDS ARE ON THE STEADY DECLINE THIS MORNING AS PRESSURE RISES
MOVING ACROSS THE CWA ARE WEAKENING THE GRADIENT. A BRIEF RESPITE
FROM THE WINDS AND SNOW WILL OCCUR THROUGH EARLY THIS
AFTERNOON...BUT THE NEXT BOUT OF WINDS WILL DEVELOP LATE THIS
AFTERNOON AS A SHORTWAVE SKIRTS ACROSS THE NORTHERN ROCKIES AND
RAPIDLY DEEPENS THE LEESIDE PRESSURE TROUGH. THE WRKHGT PRODUCT
SHOWS THE GRADIENT STRENGTHENING TO BETWEEN 70 AND 75 DAM BY 00Z
THIS EVENING...WITH MODELS DEVELOPING 55 TO 70 KT WINDS AT 700 MB
OVER MUCH OF THE CWA. DEEP MOUNTAIN WAVE ACTIVITY AND WEAK WAA AT
ROUGHLY 600 TO 650 MB WILL BRING SOME OF THESE STRONGER WINDS TO THE
SFC LATE THIS AFTERNOON FOR MANY AREAS ALONG AND WEST OF INTERSTATE
25...WITH STRONG WINDS PERSISTING THROUGH EARLY SATURDAY MORNING AS
THE SFC TROUGH SHIFTS EAST. WILL UPGRADE THE WATCH TO A WARNING
SHORTLY (AFTER A SUFFICIENT BREAK BETWEEN THE PREVIOUS WARNING AND
NEW WARNINGS)...AND WILL EXPAND TO INCLUDE THE LARAMIE
VALLEY...NORTHERN CARBON COUNTY...AND ALSO THE SNOWY RANGE. WINDS AT
THE TOP OF SNOWY WILL BE ON THE ORDER OF 60 TO 70 KTS...WITH
SOMEWHAT STEEP LAPSE RATES ABOVE THE MOUNTAIN WHICH WILL ALLOW
HIGHER GUSTS TO MIX DOWN TO THE SURFACE. SO FEEL JUSTIFIED IN
INCLUDING THIS AREA IN THE WARNING AS WELL. WILL START ALL AREAS
AT 21Z...WITH THE NORTHERN CARBON COUNTY AND LARAMIE VALLEY
WARNING ENDING EARLY AT 12Z AND THE REMAINING AREAS CONTINUING
THROUGH 19Z. A FETCH OF PACIFIC MOISTURE WILL RETURN TO THE
MOUNTAINS LATE FRIDAY THROUGH SATURDAY MORNING...SO WILL LIKELY
SEE SNOW INCREASE DURING THIS TIME. LOOKING AT ONLY A COUPLE
INCHES OF POTENTIAL ACCUMULATIONS THO...SO WILL ONLY MENTION
BLOWING SNOW IN THE HWW.

THE COLD FRONT ASSOCIATED WITH THE NEXT WAVE WILL SLIDE SOUTH INTO
THE EASTERN PLAINS LATE TONIGHT INTO SATURDAY. LOOKING AT ANOTHER
ROUND OF SNOW ACROSS EAST CENTRAL WYOMING AND THE NORTHERN NEBRASKA
PANHANDLE WITH INCREASING FRONTOGENESIS AND SOME WEAK UPPER LEVEL
DYNAMICS OVERHEAD THROUGH THIS TIME. TEMPERATURES ARE PROGGED TO BE
WARMER IN GENERAL...SO LOOKING AT A MIX OF RAIN AND SNOW WITH QUICK
MELTING OF ANY SNOW THAT DOES ACCUMULATE. STILL COULD SEE ANOTHER
QUICK 1 TO 3 INCHES WITH THE HEAVIER SNOW SHOWERS THAT FORM WITHIN
THE FRONTOGENESIS BAND AS NAM DOES SHOW EPV VALUES RANGING FROM -0.1
TO -0.5 HERE. A FEW SHOWERS LOOK TO DEVELOP FURTHER SOUTH ACROSS THE
PANHANDLE TOO WITHIN THE CONVERGENCE ZONE OF THE SFC TROUGH. A
SHORTWAVE RIDGE BUILDING IN FROM THE WEST LATE SATURDAY WILL BRING
DRIER BUT CONTINUED BREEZY CONDITIONS TO THE FORECAST AREA THROUGH
SATURDAY NIGHT.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 509 AM MST FRI FEB 14 2014

SUNDAY...PROGRESSIVE POSITIVELY TILTED SHORTWAVE TROUGH ALOFT AND
ITS ASSOCIATED COLD FRONT AND BAROCLINIC BAND WILL MOVE QUICKLY
ACROSS WYOMING DURING THE DAYLIGHT HOURS...SPREADING SCATTERED TO
NUMEROUS SNOW SHOWERS ACROSS OUR CARBON COUNTY ZONE...WITH
CATEGORICAL POPS OVER THE SNOWY AND SIERRA MADRE RANGES.
DOWNSLOPING...OR SNOW SHADOWING EFFECTS WILL SEVERELY LIMIT
PRECIPITATION CHANCES TO THE LEE OF THE MOUNTAINS.

BASED ON COLD FRONTAL TIMING LATER IN THE DAY...MAXIMUM TEMPERATURES
WILL STILL BE ABLE TO SOAR TO NEAR 60 DEGREES ALONG AND EAST OF
INTERSTATE 25 DUE TO THE KATABATIC WARMING AND CHINOOK WINDS SO
PREVALENT ACROSS EASTERN WYOMING.

MONDAY...STRONG ZONAL...WEST TO EAST...FLOW ALOFT AND MINIMAL LOW
AND MID LEVEL MOISTURE WILL PRODUCE A DRY...WINDY AND RELATIVELY
MILD DAY...ALBEIT COOLER THAN SUNDAY IN THE WAKE OF THE COLD FRONTAL
PASSAGE...THOUGH TEMPERATURES WILL STILL BE RELATIVELY MILD FOR MID
FEBRUARY.

TUESDAY...FAST MOVING SHORTWAVE TROUGH WILL SCOOT EASTWARD ACROSS
MONTANA AND THE DAKOTAS...THOUGH NOT ENOUGH LOW AND MID LEVEL
MOISTURE OVER OUR COUNTIES FOR ANY PRECIPITATION.

WEDNESDAY...NEXT FAST MOVING SHORTWAVE TROUGH ALOFT AND ASSOCIATED
COLD FRONT MOVE INTO WYOMING. THE 14/00Z GFS SHOWS MINIMAL AMPLITUDE
WITH THIS SHORTWAVE TROUGH WHILE THE 14/00Z ECMWF IS PREFERRED WITH
MORE AMPLITUDE...AS THE ECMWF TENDS TO OUTPERFORM THE GFS IN THE
WINTER MONTHS...AND THUS WILL PAINT WIDESPREAD OROGRAPHIC SNOW
SHOWERS OVER THE SNOWY AND SIERRA MADRE RANGES...WITH SCATTERED
SNOWS NEARBY. SNOW SHADOWING EFFECTS DOWNWIND OF THE MOUNTAINS WILL
LIMIT PRECIPITATION COVERAGE ALONG AND EAST OF INTERSTATE 25.

THURSDAY...MOIST WEST FLOW ALOFT WILL CONTINUE THE OROGRAPHIC SNOW
MACHINE OVER THE SNOWY AND SIERRA MADRE RANGES...AS WELL DEPICTED BY
THE ECMWF AND GFS...THOUGH LOW AND MID LEVEL DOWNSLOPING WINDS AND
LIMITED DYNAMICS WILL KEEP OTHER LOCALES DRY.

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SATURDAY MORNING)
ISSUED AT 509 AM MST FRI FEB 14 2014

SNOW HAS ENDED ACROSS THE FORECAST AREA EARLY THIS MORNING...WITH
MANLY JUST BREEZY WEST TO NORTHWEST WINDS OCCURRING AT THE

UNTIL SNOW SHOWERS DEVELOP AND MOVE OFF THE MOUNTAINS NEAR KRWL THIS
AFTERNOON. ANOTHER COLD FRONT WILL DROP SOUTH ACROSS THE PLAINS
AFTER MIDNIGHT TONIGHT...WITH SNOW SHOWERS MOVING IN FROM THE NORTH

THE PLAINS AFTER 12Z SATURDAY...WITH GUSTY NORTH TO NORTHWEST WINDS
EXPECTED ALONG WITH THE SNOW. FURTHER WEST...STRONG WINDS WILL
