AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
446 AM MDT TUE MAR 30 2010

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...
ANOTHER WARM...WINDY AND DRY DAY ON TAP FOR THE CWA TODAY.  MAIN
ISSUE CONTINUES TO BE THE POSSIBILITY OF HIGH WINDS IN AREAS ALONG
AND WEST OF THE LARAMIE RANGE.  SINCE THE LATE EVENING...WINDS HAVE
INCREASED IN MANY AREAS.  KDGW HAD A GUST TO 50 MPH AROUND 0830Z
WITH GUSTS TO 49 AT KARL FOR MUCH OF THE EARLY MORNING.  THE WINDS
AT THE LOWEST GATE OF THE MEDICINE BOW PROFILER HAVE ALSO INCREASED
BACK TO 50 KNOTS AS OF 08Z.  POTENTIAL STILL EXISTS FOR THE HIGH
WINDS THROUGH THE EARLY EVENING WITH TIGHT SURFACE PRESSURE GRADIENT
AND INCREASING WINDS ALOFT.  THE WYOMING PART OF THE CWA WILL BE
UNDER THE RIGHT EXIT REGION OF THE 300 MB JET.  THE NEGATIVES FOR
THE HIGH WINDS ARE THE WARM TEMPERATURES AND BEST SURFACE PRESSURE
FALLS CURRENTLY OVER THE CWA.  WILL CONTINUE THE HIGH WIND WARNING
AT THIS TIME UNTIL 03Z.  TEMPERATURES OVER THE LOWER ELEVATIONS ARE
IN THE 40S AND 50S EARLY THIS MORNING.  WITH EVEN WARMER 700 MB
TEMPERATURES AND THE DOWNSLOPE WINDS ADDED TO THE WARM START...TODAY
SHOULD BE THE WARMEST DAY SO FAR.  HAVE BUMPED UP HIGHS FOR TODAY AND
EVWEN THE WARMER MAV GUIDANCE MAY BE TOO LOW.  THE OTHER ISSUE WILL
BE WITH FIRE WEATHER AND WILL DISCUSS IN THAT PORTION OF THIS AFD.
SURFACE DEW POINTS CONTINUE TO BE WELL BELOW GUIDANCE IN MANY AREAS
AND THIS WILL COME INTO PLAY LATER TODAY FOR POSSIBLE HIGHLIGHTS.

THE CURRENT WEST COAST STORM SYSTEM WILL MOVE SLOWLY OVER THE
WESTERN PART OF THE NATION THROUGH 12Z THURSDAY.  AT THAT TIME...A
CLOSED LOW WILL HAVE FORMED IN THE MID AND UPPER LEVELS OVER
CALIFORNIA AND NEVADA.  THE ASSOCIATED PACIFIC COLD FRONT FRONT WAS
LOCATED FROM WESTERN MONTANA TO WESTERN NEVADA AT 06Z WILL MOVE
ACROSS THE CWA TONIGHT AND EARLY WEDNESDAY MORNING.  WINDS SHOULD
SUBSIDE WITH FRONTAL PASSAGE DUE TO A WEAKER SURFACE PRESSURE
GRADIENT.  TEMPERATURES WILL BE COOLER BEHIND THE FRONT FOR WEDNESDAY
AND WEDNESDAY NIGHT.  MOISTURE AND SYNOPTIC LIFT WILL INCREASE OVER
THE CWA TONIGHT THROUGH WEDNESDAY NIGHT FROM NORTHWEST TO SOUTHEAST.
WILL INTRODUCE LOW POPS INTO THE FAR WEST PART OF THE CWA LATE THIS
AFTERNOON AND THEN INCREASE POPS OVER THE WEST AND NORTH PARTS OF THE
CWA TONIGHT AND WEDNESDAY.  THE PRECIPITATION WILL BE A MIX OF RAIN
OR SNOW SHOWERS OVER THE LOWER ELEVATIONS.  A FEW WEAK THUNDERSTORMS
ARE ALSO POSSIBLE IN THE FAR WEST PART OF THE CWA LATE THIS
AFTERNOON.  SHOWERS WILL BE OVER MOST OF THE CWA WEDNESDAY NIGHT AND
HAVE BUMPED UP POPS FOR THAT TIME PERIOD.  THE MOUNTAINS SHOULD
RECEIVE SEVERAL INCHES OF NEW SNOW WEDNESDAY NIGHT.  THE SNOW LEVEL
WILL GRADUALLY LOWER WEDNESDAY NIGHT...BUT RAIN SHOULD BE THE MAIN
PRECIPITATION TYPE FOR THE PANHANDLE.

.LONG TERM...THURSDAY THROUGH MONDAY
WENT WITH THE SLOWER AND MORE CONSISTENT ECMWF IN THE LONG TERM.  SW
FLOW WILL BE ALOFT ON THUR AS AN UPPER TROUGH AXIS MOVES TO WESTERN
WY.  DISTURBANCES WILL MOVES ACROSS THE CWA IN THE SW FLOW AHEAD OF
THE MAIN UPPER LOW.  MOISTURE WILL ALSO INCREASE AT THIS TIME SO
SNOW SHOWERS WILL BE LIKELY ACROSS THE FORECAST AREA WITH THE SNOW
SHOWERS CHANGING TO RAIN IN THE AFTERNOON.  SNOW WILL BE LIKELY
ACROSS THE ENTIRE CWA THUR NIGHT AS THE UPPER TROUGH AXIS MOVES VERY
SLOWLY ACROSS WESTERN WY.  THE CLOSED LOW AT 700 MB WILL BE OVER THE
AREA AT THIS TIME AND COLD AIR ADVECTION WILL CONTINUE FROM THUR
NIGHT THROUGH FRI MORNING. A CHANCE OF SNOW SHOWERS CAN BE EXPECTED
ACROSS THE CWA FRI MORNING...WITH SNOW CHANGING TO RAIN EAST OF THE
LARAMIE RANGE IN THE AFTERNOON.  THE PRECIP WILL FINALLY END FRI
NIGHT AS THE UPPER TROUGH AXIS MOVES EAST OF THE FORECAST AREA.
ANOTHER DISTURBANCE IN THE NW FLOW AHEAD OF THE WEAK UPPER RIDGE
MOVING ACROSS THE INTER-MOUNTAIN WEST WILL AFFECT THE NORTHERN
PORTIONS OF THE PANHANDLE SAT AFTERNOON AND EVENING.  THIS WILL
RESULT IN A CHANCE OF SHOWERS FOR THIS AREA DURING THIS TIME.  SUN
AND MON WILL BE DRY AS A UPPER RIDGE AMPLIFIES AS IT MOVES ACROSS
THE PLAINS STATES.  HIGH TEMPERATURES WILL BE FROM 6 TO 10 DEGREES
BELOW NORMAL ON THUR AND FRI...AROUND NORMAL ON SAT...AND THEN FROM
6 TO 10 DEGREES ABOVE NORMAL ON SUN AND MON.

&&

AVIATION...VFR CONDITIONS WILL OCCUR OVER THE CWA TODAY AND TONIGHT.
CLOUDS WILL GRADUALLY INCREASE AND BASES LOWER FROM WEST TO EAST OVER
THE CWA WEDNESDAY AND WEDNESDAY NIGHT.  AREAS OF MVFR CEILINGS AND
VISIBILITIES WILL BE ASSOCIATED WITH SHOWERS OVER THE WEST AND NORTH
PARTS OF THE CWA WEDNESDAY AFTERNOON.  MVFR CEILINGS AND VISIBILITIES
IN RAIN AND SNOW SHOWERS WILL BE MORE COMMON OVER THE ENTIRE CWA
WEDNESDAY NIGHT.  THE SNOWY RANGE WILL LIKELY BE OBSCURED WEDNESDAY
AFTERNOON AND WEDNESDAY NIGHT.  A FEW THUNDERSTORMS WILL BE POSSIBLE
OVER WESTERN CARBON COUNTY LATE THIS AFTERNOON AND EARLY EVENING.

SOUTHWEST SURFACE WINDS WILL GUST AS HIGH AS 50 KNOTS IN AREAS ALONG
AND WEST OF THE LARAMIE RANGE THROUGH THIS EVENING.  A MODERATE
MOUNTAIN WAVE CAN BE EXPECTED AS WINDS AT MOUNTAIN TOP LEVEL WILL BE
AROUND 50 KNOTS.  THOSE WINDS WILL HAVE SOMEWHAT OF A LESS
PERPINDICULAR COMPONENT THAN ON MONDAY AS THE FLOW ALOFT SLOWLY
BACKS.  TURBULENT CONDITIONS SHOULD BE ANTICIPATED THROUGHOUT MUCH
OF THE ATMOSPHERE AGAIN TODAY.

&&

FIRE WEATHER...
TODAY WILL BE ANOTHER CRITICAL DAY IN REGARDS TO FIRE WEATHER AND
FIRE SPREAD POTENTIAL.  HAVE ISSUED A RED FLAG WARNING FOR THE NORTH
PART OF THE CWA BASED ON EXPECTED WARM...DRY AND WINDY CONDITIONS.
THAT AREA ALSO HAS DRIER SMALL FUELS PER DISCUSSIONS WITH LAND
MANAGEMENT AGENCIES MONDAY MORNING.  THE RED FLAG WARNING WILL RUN
FROM 15Z TO 01Z THIS EVENING.  RELATIVE HUMIDITY VALUES WILL AGAIN
BE LOW AND LIKELY LOWER THAN EXPECTED.  ALREADY AT 08Z...SOME PLACES
TO THE LEE OF THE LARAMIE RANGE HAVE RELTIVE HUMIDTY VALUES OF 15 TO
25 PERCENT.  FOR MUCH OF TODAY...TEMPERATURES WILL BE WELL ABOVE
NORMAL AND MINIMUM RELATIVE HUMIDITY VALUES WILL RANGE FROM 8 TO 13
PERCENT OVER THE LOWER ELEVATIONS.  SOUTHWEST SURFACE WINDS WILL BE
STRONGEST ALONG AND WEST OF THE LARAMIE RANGE...BUT EVEN IN THE
NORTHERN PANHANDLE WIND GUSTS SHOULD BE FROM 25 TO 30 MPH.  SOME SNOW
COVER AND WETTER FUELS EXIST OVER THE LOWER ELEVATIONS OF THE REST OF
SOUTHEAST WYOMING AND SO THAT AREA WAS NOT INCLUDED IN THE WARNING.
LIKEWISE...THE SOUTHERN PANHANDLE SHOULD HAVE LIGHTER WINDS TODAY AND
WERE ALSO LEFT OUT OF THE WARNING AREA.  A COLD FRONT WILL MOVE
ACROSS THE CWA TONIGHT WITH WINDS DECREASING...RELATIVE HUMIDITY
VALUES INCREASING AND TEM[PERATURES LOWERING.  THAT TREND WILL
CONTINUE THROUGH THURSDAY AS A STORM SYSTEM WILL AFFECT THE AREA.
