AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
934 PM MST SUN NOV 28 2010
.UPDATE...SNOWFALL AMOUNTS ARE STARTING TO APPROACH ADVISORY
CRITERIA AT KRWL AND THE NORTHERN LARAMIE RANGE AS OF 04Z. HAVE
WENT AHEAD AND ADDED THOSE AREAS TO THE WINTER WEATHER ADVISORY
AND GOES TIL 22Z MONDAY.
&&
.AVIATION...06Z TAF ISSUANCE...
MVFR CEILINGS AND VISIBILITIES WERE OVER MOST AREAS ALONG AND WEST OF
THE LARAMIE RANGE LATE THIS EVENING. THE LOWER CEILINGS AND
VISIBILITIES IN SNOW WILL SPREAD BACK EAST AND OVER THE ENTIRE CWA
BY 09Z AND PERSIST FOR MUCH OF MONDAY. IFR CONDITIONS...ESPECIALLY
VISIBILITIES WILL ALSO OCCUR AT TIMES...MAINLY THROUGH 15Z. THE
MOUNTAINS WILL BE OBSCURED THROUGH 00Z TUESDAY. NORTHERLY WINDS
WILL ALSO INCREASE LATER TONIGHT AND CONTINUE THROUGH MONDAY. GUSTS
WILL BE AS HIGH AS 40 KNOTS AND WILL PRODUCE AREAS OF BLOWING AND
DRIFTING SNOW.
&&
.PREVIOUS DISCUSSION.../ISSUED AT 240 PM MST SUN NOV 28 2010/...
SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT...CURRENT KCYS RADAR LOOP
SHOWS SNOW CONTINUING TO DEVELOP EARLY THIS AFTERNOON MAINLY ALONG
I80 FROM JUST WEST OF CHEYENNE WESTWARD TO ELK MOUNTAIN AND SARATOGA
SPRINGS. CURRENT OBS HAVE SHOWN ONE HALF MILE VISIBILITIES OR LOWER
AROUND THE I80 SUMMIT AS WELL AS LARAMIE AND ARLINGTON. SNOWFALL IS
STARTING TO DEVELOP ALONG THE LARAMIE RANGE FOOTHILLS SOUTHWARD
TOWARDS THE FOOTHILLS OF THE ROCKIES AS WELL. WITH RECENT MODEL
TRENDS SHOWING THE UPPER LEVEL TROUGH BECOMING A CLOSED LOW OVER NE
COLORADO THIS EVENING AND A DEVELOPING SURFACE LOW IN THE VICINITY
OF EASTERN COLORADO...THERE IS SOME CONCERN OF HIGHER SNOW AMOUNTS
SINCE MODELS HAVE TRENDED HIGHER ON LOW TO MIDLEVEL OMEGA IN THE
LAST SEVERAL RUNS...HINTING TOWARDS MORE LIFT AND LLVL DYNAMICS.
STILL EXPECT LIGHT TO MODERATE SNOW AMOUNTS...BUT SNOW ACCUMULATIONS
IN SOME AREAS SUCH AS THE LARAMIE RANGE AND NORTH FACING RIDGES MAY
BE CLOSE ENOUGH TO WINTER WEATHER ADVISORY CRITERIA WITH AMOUNTS
AROUND 3 OR 4 INCHES WITH NEARLY 6 ACROSS THE NORTHERN LARAMIE
RANGE. WILL MONITOR THIS THROUGH THE EVENING. FOR NOW...KEPT THE
WINTER WEATHER ADVISORY GOING FOR THE SIERRA MADRE AND SNOWY RANGES
THROUGH MONDAY. DUE TO THE DEVELOPING SURFACE LOW SOUTHEAST OF THE
REGION COMBINED WITH BUILDING HIGH PRESSURE ACROSS THE
ROCKIES...EXPECT NORTHWEST WINDS TO INCREASE TONIGHT. WITH STRONG
GUSTY WINDS EXPECTED EAST OF THE LARAMIE RANGE STARTING LATE TONIGHT
AND THROUGH MONDAY...ISSUED A WIND ADVISORY FOR THE PANHANDLE OF
NEBRASKA FROM MONDAY MORNING THROUGH MONDAY EVENING FOR WINDS
SUSTAINED BETWEEN 25 TO 35 MPH AND GUSTS AROUND 50 MPH POSSIBLE BY
MONDAY AFTERNOON.
MUCH COLDER AIR WILL PUSH INTO THE REGION FOR MONDAY WITH 700MB
TEMPS LOWERING TO BELOW -15C. EXPECT HIGH TEMPS FOR MONDAY TO
STRUGGLE TO REACH INTO THE MID 20S WITH MAINLY TEENS FOR HIGHS
ACROSS THE HIGHER ELEVATIONS OVER 6000 FEET. PERIODS OF SNOW WILL
CONTINUE THROUGH MONDAY EVENING...ESPECIALLY NORTH AND NORTHWEST
FACING SLOPES AND RIDGES. STRONG WINDS AND COLDER AIR MAY RESULT
IN VERY COLD WIND CHILLS WITH VALUES DOWN TO -5 TO -15F ACROSS
PORTIONS OF THE AREA BY MONDAY EVENING. SNOW WILL TAPER TO
SCATTERED FLURRIES BY MIDNIGHT...AND WITH CLEARING SKIES...LOWS
MONDAY NIGHT AND TUESDAY MORNING WILL BE MAINLY IN THE SINGLE
DIGITS TO LOW TEENS ACROSS MOST OF THE REGION WITH TEMPS NEAR ZERO
TO A FEW DEGS BELOW ZERO WEST OF THE LARAMIE RANGE. WARMER TEMPS
ARE EXPECTED BY TUESDAY AS A RIDGE OF HIGH PRESSURE NUDGES
WESTWARD ACROSS THE INTER MOUNTAIN WEST...BUT HIGH TEMPS ON TUESDAY
WILL STILL BE 5 TO 10 DEGS BELOW NORMAL.
LONG TERM...WEDNESDAY THROUGH SUNDAY
A PROGRESSIVE PATTERN WILL DOMINATE THE EXTENDED
PERIOD...ALTERNATING BETWEEN UPPER RIDGES AND UPPER TROUGHS OVER
THE FORECAST AREA. NW FLOW WILL BE ALOFT ON WED WITH SOME SNOW
SHOWERS IN THE SOUTHERN MOUNTAINS. COOL TEMPERATURES WILL OCCUR
ACROSS THE AREA. ON THUR...DRY CONDITIONS WILL PREVAIL AS THE
UPPER RIDGE MOVES OVER THE FORECAST AREA. WARMER TEMPERATURES WILL
ALSO OCCUR THUR AS THE THERMAL RIDGE MOVES OVER THE CWA. A WEAK
SHORT WAVE WILL BEGIN TO MOVE ACROSS THE AREA THUR NIGHT AND THIS
WILL RESULT IN A CHANCE OF SNOW SHOWERS MAINLY IN THE SOUTHERN
MOUNTAINS FOR FRI MORNING. AN UPPER RIDGE WILL BUILD ONCE AGAIN TO
THE WEST OF THE FORECAST AREA ON FRI...RESULTING IN NW FLOW ALOFT.
A COLD FRONT WILL ASSOCIATED WITH THE FRI MORNING SHORT WAVE WILL
ALSO DRAG A COLD FRONT ACROSS THE CWA BY FRI EVENING...THEREFORE TEMPS
WILL BE COLDER ON SAT. SW FLOW WILL DEVELOP ALOFT SAT NIGHT AS AN
UPPER TROUGH MOVES OVER THE WESTERN U.S. AND THE UPPER RIDGE MOVES
EAST. FINALLY FOR SUN...AN UPPER LOW WILL FORM OVER UTAH WITH SW
FLOW CONTINUING OVER THE CWA. SNOW SHOWERS WILL DEVELOP IN THE
SOUTHERN MOUNTAINS AT THIS TIME. GOOD DIVERGENT FLOW WILL BE ALOFT
OVER THE FORECAST AREA AND WILL NEED TO SPREAD PRECIP EAST ACROSS
THE CWA AS TIME FRAME APPROACHES AND BASED ON FUTURE MODEL RUNS.
HIGH TEMPERATURES WILL BE AROUND NORMAL FOR WED THROUGH FRI...AND
FROM 5 TO 7 DEGREES BELOW NORMAL FOR SAT AND SUN.
&&
.AVIATION...18Z TAFS. MVFR CONDITIONS WILL SPREAD FROM THE WEST TO
THE EAST TONIGHT. LO CIGS AND VSBYS DUE TO FOG AND FALLING SNOW
WILL OCCUR OVER THE WY PORTION OF THE AREA OVERNIGHT. SOME LOCAL
IFR CONDITIONS WILL ALSO OCCUR. THESE CONDITIONS WILL SPREAD INTO
THE NEB PANHANDLE EARLY MON MORNING AND CONTINUE UNTIL AROUND
NOON. AFTER NOON CONDITIONS SHOULD BEGIN TO IMPROVE TOWARDS VFR BY
SUNSET.
&&
.FIRE WEATHER...A PACIFIC STORM SYSTEM WILL MOVE ACROSS THE REGION
THROUGH MONDAY BRINGING LIGHT SNOW AND COLDER TEMPERATURES.
