AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
913 PM MST SUN JAN 11 2009
.UPDATE...TONIGHT...
HAVE HAD TO REISSUE THE HIGH WIND WARNING THROUGH MIDNIGHT MST AS
THE WINDS AT ARLINGTON AND IN THE EXTREME SOUTHERN PORTION OF THE
LARAMIE RANGE CONTINUED TO EXCEED HIGH WIND CRITERIA. WINDS HAVE
STARTED TO SUBSIDE AS OF 800 PM MST...BUT WILL MONITOR FOR A
LITTLE WHILE BEFORE CANCELING THE HIGHLIGHT. BELIEVE THAT PRESSURE
RISES AS THE PRE-FRONTAL TROUGH SLID EAST OVER THE AREA WERE
ALLOWING THE WINDS TO REMAIN HIGH LONGER THAN PREVIOUSLY EXPECTED.
ALSO MADE ADJUSTMENTS TO TEMPERATURES OVERNIGHT AND FOR MONDAY
BEHIND THE COLD FRONT.
MAIN CHALLENGE FOR OVERNIGHT IS THE DEVELOPMENT OF SNOW SHOWERS
WITH THE FRONTAL PASSAGE. SURFACE PRESSURE RISES ASSOCIATED WITH
THE ACTUAL COLD FRONT ALREADY MOVING ACROSS NORTHEAST WYOMING AND
WILL QUICKLY MOVE SOUTH ACROSS THE AREA OVERNIGHT. VERY STRONG
PRESSURE RISES AND ASSOCIATED VERY STRONG WINDS WILL REMAIN
NORTHEAST OF THE AREA AND HOLD OFF UNTIL EARLY MONDAY ACROSS
EASTERN MONTANA AND THE DAKOTAS. ALTHOUGH THE AREA WILL BE SPARED
THE STRONGEST WINDS WITH THIS CLIPPER SYSTEM...THE
GFS...EUROPEAN...WRF-NMM AND RUC MODELS ARE ALL HINTING AT THE
DEVELOPMENT OF A BAND OF SNOW EAST OF THE LARAMIE RANGE OVERNIGHT
TONIGHT. THIS BANDED PRECIPITATION IS INDICATED OVERNIGHT IN THE
MODELS HANDLING OF THE MID-LEVEL FRONTOGENESIS...700-500MB LAPSE
RATES OF 7.5 TO 8.0 DEG C/KM...AND GOOD SUPPORT ALOFT FROM THE
LEFT EXIT REGION OF THE NORTH TO SOUTH JET STREAK OVERHEAD.
INCREASING OROGRAPHIC SNOW SHOWERS ARE EXPECTED AS WELL...WITH THE
MOUNTAIN AREAS OF SOUTHEAST WYOMING EXPECTED TO RECEIVE 3 TO 6
INCHES OF SNOW BY EARLY MONDAY. SNOW SHOWERS WERE ONGOING IN THE
HIGHEST TERRAIN OF THE SNOWY RANGE AROUND SUNSET...SO GAINING
CONFIDENCE ON THESE SNOW ACCUMULATIONS.
NO CHANGES PLANNED FOR THE WIND ADVISORY ACROSS THE NEBRASKA
PANHANDLE AS THIS POST-FRONTAL PASSAGE FEATURE CONTINUES TO LOOK
GOOD FOR MONDAY.
&&
.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...
PERSISTENT NW FLOW ALOFT WILL CONTINUE TUE NIGHT WITH A STRONG
SHORTWAVE TROUGH RACING OUT OF DAKOTAS INTO THE UPPER MS VALLEY.
FLOW ALOFT WILL VEER SLIGHTLY TO NNW ON WED WITH AN ARCTIC COLD
FRONT MOVING FROM NORTH TO SOUTH ACROSS MAINLY OUR EASTERN HALF OF
THE CWA BEFORE STALLING ROUGHLY FROM KLND TO KLAR. THERE WILL BE
A NARROW BAND OF LIGHT SNOW BEHIND THIS ARCTIC FRONT AND THIS WILL
FOLLOW BEHIND IT AFFECTING MAINLY EAST CENTRAL WY AND PARTS OF THE
WESTERN NEBRASKA PANHANDLE. SOME OF THIS WILL LINGER OVER THE
EASTERN CWA INTO THURSDAY MORNING. WEST OF THE LARAMIE RANGE...
THE ONGOING OROGRAPHIC SNOW SHOWERS WILL ALSO CONTINUE TUE NIGHT
THROUGH WED NIGHT BEFORE DECREASING THU. REMAINS OF ARCTIC COLD
FRONT WILL HAVE RETREATED TO FAR EASTERN CWA BY THU AFTERNOON AS
RISING UPPER HEIGHTS START TO BUILD IN FROM THE WEST. THIS TREND
WILL PREVAIL THROUGH FRIDAY BRINGING DRY AND WARMER CONDITIONS.
FLOW ALOFT WEAKENS SOME FRI NIGHT AND SATURDAY AS A RATHER WEAK
LOOKING SHORTWAVE TROUGH SLIPS ACROSS WY FROM THE NNW. MODELS
ARE HAVING SOME DIFFICULTIES ON THE STRENGTH OF THIS FEATURE
WITH NEITHER THE GFS OR THE ECMWF SHOWING ANY QPF AT THIS TIME.
STILL...A WEAK COLD FRONT WILL LIKELY MOVE THROUGH CWA ON SAT
BRINGING TEMPS BACK DOWN FROM THOSE ON FRI. WARMER AGAIN ON
SUNDAY AS SHARP UPPER RIDGE TO THE WEST GETS A BIT CLOSER.
&&
.AVIATION...
MOUNTAIN OBSCURATION WAS APPARENT IN THE SNOWY AND SIERRA MADRE
RANGES AROUND SUNSET THIS EVENING...AND WILL ONLY INCREASE AS SNOW
SHOWER ACTIVITY INCREASES WITH THE PASSING FRONTAL SYSTEM
OVERNIGHT AND MONDAY. AWAY FROM THE HIGHER TERRAIN...EXPECT MVFR
CEILINGS TO DEVELOP FROM NORTH TO SOUTH OVERNIGHT WITH THE FRONTAL
PASSAGE. AREAS OF IFR AND LOCALIZED LIFR WILL BE POSSIBLE NEAR THE
STRONGEST SNOW SHOWERS. EXPECT CONDITIONS TO IMPROVE TO VFR BY
MONDAY EVENING ACROSS THE AREA...EXCEPT FOR LINGERING MOUNTAIN
OBSCURATION IN THE SIERRA MADRE AND SNOWY RANGES.
