AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
858 PM MDT SUN MAR 23 2008

.DISCUSSION...WINDS HAVE BEEN STEADILY INCREASING OVER MUCH OF
CARBON COUNTY THE PAST FEW HOURS.  LATEST PEAK GUST FROM KARL WAS
UP TO 55 MPH.  CURRENTLY THERE ARE 4 MB 3 HOURLY SURFACE PRESSURE
FALLS TO THE NORTH OF THE CWA...WITH SIMILAR VALUES UPSTREAM.
PARAMETERS LOOK FAVORABLE FOR HIGH WINDS IN THE WIND CORRIDOR
DURING THAT TIME.  THE SURFACE PRESSURE GRADIENT TIGHTENS LATER
TONIGHT AND MONDAY AND THE LOW LEVEL HEIGHT DIFFERENCES BETWEEN
KCAG AND KCPR STILL PEAK AT AROUND 70 METERS AROUND 18Z FROM THE
00Z NAM RUN.  THE 300 MB JET ALSO MOVES ACROSS NORTHERN WYOMING
ON MONDAY.  HAVE BUMPED UP THE TIMING A BIT DUE TO THE ALREADY
STRONG WINDS IN CARBON COUNTY.  STRONGEST WINDS OVER THE CWA SHOULD
STILL BE FROM MID MORNING THROUGH EARLY EVENING MONDAY.  THE WARM
TEMPERATURES ON MONDAY WILL BE A NEGATIVE BUT SHOULD BE OVERCOME
BY THE STRONG SUBSIDENCE.  HAVE KEPT THE WATCH IN PLACE FOR WESTERN
LARAMIE COUNTY AND MAY NEED A WIND ADVISORY FOR PARTS OF THE
PANHANDLE ON MONDAY.

&&

.PREVIOUS DISCUSSION.../ISSUED AT 150 PM MDT SUN MAR 23 2008/

SHORT TERM...TONIGHT THROUGH TUESDAY...
THE PRIMARY FORECAST PROBLEM REVOLVES AROUND THE LOCATION AND
TIMING OF THE POTENTIAL HIGH WIND EVENT DEVELOPING FOR MONDAY.
BEFORE THEN...A PLEASANT NIGHT IS IN STORE AS THE UPPER RIDGE AXIS
MOVES OVERHEAD. MID/HIGH CLOUDS WILL INCREASE OVERNIGHT IN
ADVANCE OF A SHORTWAVE MOVING ALONG THE CANADA/U.S. BORDER. NEARLY
UNIDIRECTIONAL FLOW WILL TURN ZONAL MONDAY MORNING. WINDS AT 700MB
INCREASE TO ABOVE 50 KTS BY 12Z MONDAY...AND IN EXCESS OF 65 KTS
BY 21Z MONDAY. AT THE SAME TIME...THE CONVERGENT RIGHT FRONT
QUADRANT OF A 130KT JET STREAK WILL MOVE OVERHEAD AIDING IN
SUBSIDENCE AND SURFACING OF STRONGER MID-LEVEL FLOW. SO...HAVE
DECIDED TO ISSUE A HIGH WIND WATCH FOR MONDAY AND MONDAY EVENING
FOR THE LARAMIE RANGE...PLATTE COUNTY...CHEYENNE FOOTHILLS AND
NORTHERN CARBON COUNTY. A LATER START TO THE STRONGER WINDS CAN BE
EXPECTED IN THE WESTERN NEBRASKA PANHANDLE...AND IT LOOKS LIKE IT
SHOULD BE ABLE TO BE HANDLED BY AN ADVISORY. WILL LET MID SHIFT
MAKE A FINAL CALL ON THIS. WINDS SHOULD SHUT OFF BY LATE MONDAY
EVENING...AS A FRONT SLIPS SOUTH INTO THE CWA. NOT MUCH MOISTURE
ASSOCIATED WITH THIS FRONT...BUT SOME SNOW SHOWERS WILL BE
POSSIBLE PRIMARILY ACROSS THE NORTHERN LARAMIE RANGE MONDAY
NIGHT...AND THE SNOWY RANGE AND MEDICINE BOW MOUNTAINS TUESDAY
MORNING. DRY ZONAL FLOW EXPECTED ON TUESDAY...WITH BREEZY
CONDITIONS IN THE AFTERNOON.

MONDAY WILL BE THE WARMEST OF THE SHORT TERM AS COMPRESSIONAL AND
ADIABATIC WARMING WILL HELP BOOST AFTERNOON HIGHS INTO THE MID 60S
IN THE PANHANDLE. ONLY FLY IN THE OINTMENT LEE ENHANCED CLOUDINESS
WILL HELP OFFSET AT LEAST SOME OF THIS WARMING. ON TUESDAY...ABOUT
5 TO 10 DEGREES OF COOLING IS EXPECTED BEHIND COLD FRONT...ONLY IN
LOCATIONS EAST OF THE LARAMIE RANGE HOWEVER. TEMPERATURES IN THE
LARAMIE VALLEY AND CARBON COUNTY WILL BE UNCHANGED FROM MONDAY TO
TUESDAY.

LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...
MODESTLY-MOISTENED ZONAL FLOW WILL BE ESTABLISHED OVER THE
FORECAST AREA TUESDAY NIGHT INTO WEDNESDAY...WITH ISOLATED TO
SCATTERED OROGRAPHIC SNOW AND WINDY CONDITIONS ON THE MOUNTAIN LEE
SIDE. A WEAK TROUGH SHOULD SAG THROUGH THE NORTHERN ROCKIES WHICH
WILL BACK THE FLOW MORE SW AND ALLOW LIMITED MOISTURE TO SPILL
EASTWARD. NO AVAILABLE MODEL IS EXCITED ABOUT THIS SYSTEM...SO
ONLY ISOLATED POPS EAST OF THE MOUNTAINS AT THIS TIME. THE JET
WILL BE ORIENTED OVERHEAD MOST OF THE WEEK...WHICH MEANS THE COLD
AIR WILL BE HANGING AROUND JUST TO THE NORTH. AT SOME POINT...A
COLD FRONT WILL DRAG COLD AIR THROUGH...AND THIS SHOULD HAPPEN BY
LATE THURSDAY. VERY LITTLE MOISTURE PROGGED WITH THIS ONE
EITHER...SO A REDUCTION IN TEMPS AND INCREASED WINDS ARE ALL THAT
SHOULD BE EXPECTED. ECMWF AND GFS REBUILD A WEAK RIDGE BY LATE
FRIDAY...SO THE EARLY HALF OF THE WEEKEND WILL LIKELY BE WARM AND
DRY. ANOTHER TROUGH IS ON TAP FOR SUNDAY...BUT TOO EARLY TO
INTRODUCE POPS YET.

&&

.AVIATION...
VFR CONDITIONS THROUGH THE PERIOD. MID/HIGH LEVEL CLOUDS WILL MOVE
IN OVERNIGHT...BUT SHOULD NOT DROP BELOW 10 KFT. STRONG WEST WINDS
WILL DEVELOP ON MONDAY MORNING...INCREASING TURBULENCE
PARTICULARLY IN AND AROUND THE MOUNTAINS.

&&

.FIRE WEATHER...THE STRONG WINDS...WARM TEMPERATURES AND LOW RELATIVE
HUMIDITIES WILL PRODUCE CRITICAL FIRE WEATHER CONDITIONS FROM LATE
MORNING THROUGH EARLY EVENING MONDAY IN AREAS EAST OF THE LARAMIE
RANGE.  LATEST FUEL PAGE STILL SAYS FUELS NOT CONDUCIVE FOR FIRE
SPREAD THOUGH.

&&

.CYS WATCHES/WARNINGS/ADVISORIES...
WY...HIGH WIND WARNING FOR 3 AM TO 9 PM MONDAY OVER AND NEAR THE
     LARAMIE RANGE.  ZONES 62..64..66..67.
     HIGH WIND WATCH FROM 6 AM TO 9 PM MONDAY FOR WESTERN LARAMIE
