AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
825 PM PST MON MAR 13 2006

.SYNOPSIS...A PACIFIC COOL FRONT WILL MOVE ACROSS CALIFORNIA TUESDAY
BUT VERY LITTLE PRECIPITATION IS EXPECTED TO CROSS THE SIERRA CREST.
WARM GUSTY SOUTHWEST WINDS AHEAD OF THIS FRONT WILL CONTRIBUTE TO
AFTERNOON TEMPERATURES AVERAGING ABOUT 6-8 DEGREES WARMER TUESDAY
ACROSS MOST OF THE SOUTHERN GREAT BASIN AND MOJAVE DESERT.
&&

.UPDATE...FORECAST LOOKS TO BE IN GOOD SHAPE THIS EVENING. THE
LATEST MODEL RUNS CONTINUE TO KEEP THE MAIN MOISTURE WITH THE
APPROACHING SYSTEM TO THE NORTH AND HAVE TRENDED SLIGHTLY DRIER.
WILL TWEAK POPS SLIGHTLY DOWN TOMORROW ACROSS THE NORTH. THE MAIN
ISSUE IS THE HIGH WIND WATCH FOR THE EASTERN SIERRA SLOPES OF INYO
COUNTY. THE LATEST HI RESOLUTION MESOSCALE MODELS WILL BE
AVAILABLE IN THE NEXT COUPLE OF HOURS AND UNLESS THE STABILITY HAS
CHANGED IN A DETRIMENTAL MANNER WILL UPGRADE THE WATCH TO A WARNING
LATER THIS EVENING.

.PREV DISCUSSION...WATER VAPOR IMAGERY INDICATES AXIS OF WEAK SHORT
WAVE RIDGE ALOFT WAS NEAR THE NEVADA/UTAH BORDER AT 2300Z. CLOSED
LOW OFF THE OREGON COAST IS FORECAST TO OPEN UP AND TRACK EASTWARD
ACROSS THE WESTERN U.S. TOMORROW. MOISTURE AVAILABILITY IS MUCH MORE
LIMITED WITH THIS TROUGH THAN WITH THE PAST 2 OR 3 PACIFIC SYSTEMS
SO HEAVY PRECIP SHOULD BE CONFINED TO THE WESTERN SLOPES OF THE
SIERRA. HOWEVER...STRONG CROSS-BARRIER FLOW IMPINGING ON THE SIERRA
COUPLED WITH A MODERATE MOUNTAIN-TOP INVERSION SUPERIMPOSED BY
UNSTABLE AIR SUGGEST FAVORABLE CONDITIONS FOR MOUNTAIN WAVE ACTIVITY
EAST OF THE SIERRA AND GOOD POTENTIAL FOR DOWNSLOPE ACCELERATION
ALONG THE LEE SLOPES. SEVERAL MESOSCALE MODELS SUPPORT THIS SCENARIO
INCLUDING THE 4KM WRF...2KM COAMPS...AND 1KM UKMET. IT IS NOT SO
CLEAR AS TO WHETHER STRONG WINDS WILL SWEEP ACROSS THE OWENS VALLEY
THOUGH. IN FACT IT APPEARS THE VALLEY WINDS MAY WEAKEN WITH SOME
LOCATIONS SHIFTING TO A LIGHT EAST FLOW IN RESPONSE TO ROTOR
DEVELOPMENT. THEREFORE WILL OPT TO USE CAUTION AND RESTRICT HIGH
WIND WATCH TO ELEVATIONS ABOVE 5000 FEET. BELIEVE THE EVENT WILL
UNFOLD WITH INCREASING WEST WINDS OVER THE HIGHER ELEVATIONS IN THE
EARLY MORNING HOURS...FOLLOWED BY A SLIGHT DECREASE DURING THE LATE
MORNING...THEN A SECOND SURGE IN THE AFTERNOON. GUSTY SOUTHWEST
WINDS WILL ALSO SPREAD ACROSS THE HIGH DESERTS FROM SOUTHEAST
CALIFORNIA TO CENTRAL AND SOUTHERN NEVADA TOMORROW AFTERNOON IN
ASSOCIATION WITH STRENGTHENING THERMAL/PRESSURE GRADIENTS AHEAD OF
ADVANCING DRY FRONT.
&&

.LONG TERM...EXTENDED RANGE MODELS STARTING TO COME INTO GOOD
AGREEMENT WITH THE NEXT SYSTEM EXPECTED TO IMPACT THE REGION THIS
WEEKEND. WEAK ZONAL FLOW ON THURSDAY WILL GIVE WAY TO AN INCREASING
SOUTHWEST FLOW ON FRIDAY AHEAD OF THE DEEPENING TROUGH OFF THE WEST
COAST. SLIGHT DIFFERENCE IN THE GFS TO THE EURO IN REGARDS TO THE
POSITION OF THE LOW BEFORE IT IS EXPECTED TO PUSH ONSHORE SATURDAY.
A GFS SOLUTION WOULD LEAD TO HIGHER POPS AND HIGHER QPF DUE TO THE
LOW HANGING OFF SHORE LONG ENOUGH TO GRAB ADDITIONAL MOISTURE...
WHEREAS THE EURO SWINGS THE LOW INTO THE COAST A BIT QUICKER. IN
EITHER CASE THIS LOOKS TO BRING ANOTHER GOOD SHOT OF PRECIPITATION
TO THE CWA WITH FAIRLY LOW SNOW LEVELS. THIS SYSTEM NOT AS COLD AS
THE PREVIOUS SYSTEM...BUT COULD STILL SEE SNOW LEVELS AS LOW AS
BETWEEN 4000-5000 FEET. BOTH THE GFS/EURO ALSO DIFFERING ON HOW FAST
THIS SYSTEM EJECTS TO THE EAST. GFS KEEPS THE LOW OVER SOUTHERN
AREAS OF THE CWA THOUGH SUNDAY WHEREAS THE EURO PLACES IT OVER THE
FOUR CORNERS REGION. HAVE ELECTED TO LEAN WITH THE GFS DUE TO THE
FACT THERE IS NO REAL KICKER TO DISPLACE THE LOW AS FAST AS THE
EURO. HAVE GONE AHEAD AND RAISED POPS OVER THE CWA SATURDAY WITH AT
LEAST CHANCE POPS EVERYWHERE. HAVE ALSO INCREASED POPS SLIGHTLY FOR
SATURDAY NIGHT AND SUNDAY. A DRIER NORTHWEST FLOW FORECAST OVER THE
REGION MONDAY WITH WEAK RIDGING MOVING INTO THE COAST. TEMPERATURES
LOOK GOOD AND MADE ONLY MINOR CHANGES IN THAT REGARD.
&&

.AVIATION...PERIODS OF MODERATE TO SEVERE TURBULENCE CAN BE EXPECTED
THROUGH THE BEATTY CORRIDOR TOMORROW AFTERNOON IN ASSOCIATION WITH
MOUNTAIN WAVE ACTIVITY OVER AND EAST OF THE SIERRA CREST. OTHERWISE
TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER CONDITIONS FOR
AREA TERMINALS.  SEE TAFS FOR KLAS... KVGT... KDRA... KBIH...
KDAG...KEED.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.
