AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
256 AM MST TUE JAN 8 2008

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...
WATER VAPOR IMAGERY CONTINUES TO SHOW A 110 KNOT JET STREAK
MOVING EAST ACROSS THE TEXAS PANHANDLE EARLY THIS MORNING. AN
ASSOCIATED MID-LEVEL TROUGH IS LOCATED ACROSS WESTERN KANSAS AND
EASTERN COLORADO...AND MOISTURE WRAPPING NORTH AND WEST AROUND
THE BASE OF THE 700 MB LOW CONTINUES TO BE OVER SOUTHEAST WYOMING
AND WESTERN NEBRASKA THIS MORNING. THIS CLOUD COVER WILL DECREASE
AS THE STORM SYSTEM MOVES FARTHER EAST ACROSS THE GREAT PLAINS
THIS MORNING...AND ANOTHER 110 KNOT JET STREAK FROM NORTH TO
SOUTH ACROSS THE AREA ALLOWS THE UPPER LEVEL RIDGE TO MOVE
OVERHEAD. THE PRESENCE OF THE RIDGE AND DECREASED CLOUDS WILL
TRANSLATE INTO SLIGHTLY WARMER CONDITIONS ACROSS THE FORECAST
AREA TODAY.

MID-LEVEL MOISTURE WILL INCREASE AHEAD OF THE NEXT UPPER TROUGH AS
UPPER WINDS BACK FROM WEST TO SOUTHWEST TONIGHT AND HAVE INCREASED
PRECIPITATION CHANCES TO LIKELY...WITH WEST FACING SLOPES MOST
FAVORED TONIGHT IN THE SIERRA MADRE AND SNOWY RANGES.

WINDS ALSO APPEAR TO BE A CONCERN FOR TONIGHT NEAR BORDEAUX. THE
MODELS ARE SHOWING A SITUATION VERY SIMILAR TO PAST FEW NIGHTS
WHEN HIGH WIND CRITERIA WAS MET FOR SEVERAL HOURS. THE UPPER RIDGE
AXIS WILL BE EAST OF THE AREA WITH THE 500 MB TROUGH AXIS STILL TO
THE WEST. SUPPORTING FACTORS INCLUDE THE DEVELOPING LEE TROUGH AND
THE PASSAGE OF THE 700 MB TROUGH AXIS. BELIEVE THAT SUBSIDENCE
BEHIND THE 700 MB TROUGH VORTICITY MAXIMA ENHANCED THE MIXING DOWN
OF THE STRONG MID LEVEL WINDS DURING THE PAST FEW EVENTS...AND
COMBINED WITH THE INCREASING PRESSURE GRADIENT SHOULD SUPPORT
ANOTHER EPISODE OF STRONG WINDS IN THE GAP FAVORED AREA OF
BORDEAUX. OTHER AREAS OF PLATTE COUNTY WILL LIKELY HAVE JUST
BREEZY CONDITIONS OVERNIGHT. AT THIS TIME...WILL GO WITH A HIGH
WIND WATCH FOR PLATTE COUNTY VALID THIS EVENING THROUGH MID-
MORNING WEDNESDAY.

MID-LEVEL WINDS WILL VEER MORE TO THE NORTHWEST DURING THE DAY
WEDNESDAY AS THE UPPER TROUGH MOVES OVER THE AREA. WITH UPPER
LEVEL ENERGY BEGINNING TO AFFECT THE AREA...HAVE UPGRADED MOUNTAIN
PRECIPITATION CHANCES TO LIKELY. CONTINUING SURFACE PRESSURE FALLS
EAST OF THE MOUNTAINS SHOULD CONTINUE TO KEEP THE AREA DRY DURING
THE DAYLIGHT HOURS OF WEDNESDAY. A SURFACE COLD FRONT WILL SHIFT
THE WINDS TO NORTHWEST MID-AFTERNOON WEDNESDAY WITH TEMPERATURES
EXPECTED TO FALL THROUGH THE AFTERNOON HOURS. WILL SPREAD AT LEAST
A SLIGHT CHANCE FOR SNOW SHOWERS ACROSS AREAS EAST OF THE LARAMIE
RANGE WEDNESDAY NIGHT EXPECTING CONTINUE LIFT BEHIND THE FRONT.
ALSO WEDNESDAY NIGHT WILL GRADUALLY DECREASE CHANCES FOR THE
WESTERN ZONES AND HIGHER TERRAIN AS DRIER AIRMASS IS EXPECTED TO
MOVE INTO SOUTHEAST WYOMING AND THE NEBRASKA PANHANDLE.

.LONG TERM...THURSDAY THROUGH MONDAY...
NW FLOW WILL BE ALOFT OVER THE CWA THUR.  THE UPPER
RIDGE OVER THE AREA WILL BREAK DOWN THURS NIGHT WITH A DISTURBANCE
MOVING SE ACROSS THE FORECAST AREA.  BRISK WINDS WILL OCCUR IN THE
MORNING AND INCREASE AS THE DAY GOES ON AS 700 MB AND SURFACE
GRADIENTS TIGHTEN.  WILL KEEP A SLIGHT CHANCE OF SNOW SHOWERS IN THE
MOUNTAINS...BUT STRONG DOWNSLOPE WINDS WILL RESULT IN DRY CONDITIONS
ELSEWHERE.  NW FLOW WILL CONT ALF FRI AS AN UPPER RIDGE BUILDS INTO
THE PAC NW.  BRISK DOWNSLOPE WINDS WILL CONT AT THE SURFACE...SO
WILL CONT THE DRY CONDITIONS.  OROGRAPHIC EFFECTS WILL ONCE AGAIN
PRODUCE SNOW SHOWERS IN THE MOUNTAINS.  FOR SAT...THE FLOW ALOFT
WILL BECOME NORTHERLY AS THE UPPER RIDGE AXIS MOVES ACROSS SOUTHERN
CANADA AND ANOTHER UPPER RIDGE BUILDS ON THE WEST COAST.  SFC
GRADIENT WILL TIGHTEN AGAIN...RESULTING IN WINDY CONDITIONS ACROSS
THE AREA.  WILL KEEP THE SAME PATTERN GOING WITH SNOW SHOWERS IN THE
MOUNTAINS AND DRY ELSEWHERE.  NORTH FLOW WILL CONT ALF SUN AS THE
NORTHERN PORTION OF THE UPPER RIDGE GETS PUSHED EAST BY AN UPPER
TROUGH DEEPENING OVER SOUTHERN CANADA.  SNOW SHOWERS WILL LIKELY
MAKE IT EAST OF THE LARAMIE RANGE DURING THE DAY SUN.  FINALLY...DRY
CONDITIONS WILL PREVAIL ACROSS THE ENTIRE AREA MON AS SFC LEE TROUGH
SETS UP ACRS ERN WY/WRN NEB.  HIGH TEMPERATURES WILL BE AROUND
NORMAL EACH DAY.
