AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
840 AM PST SAT NOV 8 2008

.SYNOPSIS...HIGH PRESSURE WILL REMAIN OVER THE AREA TODAY FOR DRY
CONDITIONS AND ABOVE NORMAL TEMPERATURES. A PACIFIC STORM SYSTEM
WILL THEN SWEEP THROUGH THE AREA LATE TONIGHT AND SUNDAY BRINGING
COOLER TEMPERATURES...LOCALLY BREEZY TO WINDY CONDITIONS...AND A
CHANCE FOR SHOWERS. HIGH PRESSURE WILL RETURN TO THE AREA BY THE
MIDDLE OF NEXT WEEK.
&&

.UPDATE...FORECAST IN GOOD SHAPE THIS MORNING AND NO UPDATES
PLANNED. SENT A CORRECTION TO THE ZFP FOR WIND DIRECTION IN THE
SIERRA.
&&

.PREV DISCUSSION...340 AM PST SAT NOV 8...SHORT TERM...RIDGE TO
DOMINATE THE WEATHER ACROSS THE CWA TODAY AS TROUGH PUSHES ONTO THE
PACIFIC NORTHWEST COAST AND THEN BECOMES THE MAIN FEATURE FOR OUR
AREA THROUGH THE REMAINDER OF THE SHORT TERM. TROUGH TO DIG INTO
SOUTHERN NEVADA BY SUNDAY MORNING AND THEN EAST ACROSS NORTHERN
ARIZONA BY 00Z MONDAY. THIS TO RESULT IN INCREASING PRECIPITATION
ACROSS THE SOUTHERN SIERRA EARLY THIS EVENING AND THEN MAINLY THE
NORTHERN HALF OF THE CWA BY 12Z SUNDAY SHIFTING ACROSS THE EASTERN
TWO THIRDS OF THE AREA MUCH OF SUNDAY AS THE TROUGH SHIFTS INTO
ARIZONA. FAIRLY RAPID DRYING INTO MONDAY HOWEVER ENOUGH INSTABILITY
WITH POSSIBLE SECONDARY SHORT WAVE...AS SEEN ON THE EURO...TO KEEP
MENTION OF SHOWERS OVER LINCOLN/NORTHERN MOHAVE COUNTY ON
MONDAY...BEFORE DRYING MONDAY NIGHT. HEAVIEST PRECIPITATION WILL BE
ACROSS THE NORTHERN MOUNTAINS SUNDAY BUT HIGH SNOW LEVELS INITIALLY
WILL LIKELY PRECLUDE THE NEED FOR A SNOW ADVISORY. MAIN CONCERN WITH
THIS SYSTEM WILL ONCE AGAIN BE WINDS. LOCAL 4KM MODEL INDICATING
WEAK DOWNSLOPE EVENT CENTERED AROUND 12Z SUNDAY FOR THE SOUTHERN
SIERRA AND THEN SURFACE GRADIENTS/700 AND 850MB FLOW BRING SOUTHWEST
WINDS TO OUR FAVORED AREAS ESPECIALLY WESTERN SAN BERNARDINO
COUNTY...AHEAD OF THE FRONT EARLY SUNDAY AND THEN GUSTY NORTH WINDS
INTO SUNDAY NIGHT AND MONDAY. WILL POSSIBLY NEED WIND ADVISORIES IN
LATER FORECAST PACKAGES. TEMPERATURES WILL BE MILD AGAIN TODAY AHEAD
OF THE SYSTEM THEN DROP 8-12 DEGREES ON SUNDAY BEHIND THE FRONT WITH
LITTLE RECOVERY EXPECTED ON MONDAY UNDER NORTHERLY FLOW.

.LONG TERM...STILL SOME DISAGREEMENTS EARLY IN THE EXTENDED AS THE
ECMWF REMAINS STRONGER THAN THE GFS. BOTH MODELS ARE INDICATING A
SHORTWAVE MOVING THROUGH THE GREAT BASIN TUESDAY...BUT THE ECMWF
DIGS A TROUGH OVER THE 4-CORNERS REGION WHILE THE GFS ONLY SHOWS A
SLIGHT RIPPLE IN THE FLOW. THE MAIN DIFFERENCES WOULD BE IN THE
AMOUNT OF WIND AND A SLIGHT CHANCE OF PRECIPITATION OVER THE EASTERN
CWA. THE ECMWF HAS BEEN THE MOST CONSISTENT MODEL AND WILL CONTINUE
TO LEAN IN THAT DIRECTION. HAVE BACKED OFF ON THE POPS SLIGHTLY FOR
TUESDAY MORNING...BUT GHOST POPS AROUND 9-10 PERCENT REMAIN.
ALSO...DID SHOW A LITTLE NORTH WINDS DOWN THE COLORADO RIVER VALLEY.
BY WEDNESDAY...HIGH PRESSURE IS FORECAST TO BUILD INTO THE GREAT
BASIN ALLOWING FOR DRY CONDITIONS AND LIGHTER WINDS. TEMPERATURES
ARE ALSO EXPECTED TO RUN SEVERAL DEGREES ABOVE NORMAL THROUGH THE
END OF NEXT WEEK...ALTHOUGH DAILY MORNING INVERSION MAY KEEP MAXIMUM
POTENTIAL TEMPERATURES DOWN.
&&

.AVIATION...FOR MCCARRAN...GENERALLY LIGHT WINDS AND CLEAR SKIES
THROUGH MID DAY BEFORE HIGH LEVEL CLOUDS BEGIN TO MOVE OVER THE AREA
LATER THIS AFTERNOON. CHANGES WILL OCCUR LATER TONIGHT AND SUNDAY AS
A COLD FRONT MOVES THROUGH THE AREA. SOUTHWEST WINDS WILL BEGIN TO
INCREASE AROUND 12Z SUNDAY MORNING TO AROUND 10-15KTS AHEAD OF THE
COLD FRONT AND STRENGTHEN TO AROUND 14-20KTS BY 16Z. THE COLD FRONT
IS CURRENTLY FORECAST TO MOVE THROUGH THE AREA AROUND 18Z-21Z SUNDAY
WITH WINDS SHIFTING TO THE NORTHWEST AROUND 14-20KTS. CLOUDS WILL
LOWER AND THICKEN TONIGHT...PERHAPS GETTING AS LOW AS 8000 FEET
BEFORE BREAKING UP SUNDAY MORNING. A BRIEF SHOWER CANNOT BE RULED
OUT...BUT VIRGA APPEARS MORE LIKELY AT THE TERMINAL...WITH A
SLIGHTLY GREATER RISK OF SHOWERS OVER THE LOCAL MOUNTAINS AND IN THE
MORMON MESA CORRIDOR. WINDS WILL SUBSIDE ON MONDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MOSTLY CLEAR SKIES AND WINDS UNDER 10KTS CAN BE
EXPECTED TODAY BEFORE CHANGES START TO OCCUR LATER TONIGHT.
SOUTHWEST WINDS WILL START TO INCREASE OVER THE AREA OVERNIGHT
TONIGHT AHEAD OF A COLD FRONT THAT WILL MOVE THROUGH THE AREA DURING
THE DAY SUNDAY. SOUTHWEST WINDS AROUND 12-22KTS CAN BE EXPECTED
AHEAD OF THE FRONT AND NORTHWEST WINDS AROUND 12-22KTS CAN BE
EXPECTED BEHIND THE FRONT. THERE WILL BE A CHANCE OF SHOWERS TONIGHT
THROUGH SUNDAY NIGHT...MAINLY OVER THE HIGHER TERRAIN NEAR AND NORTH
OF A LINE FROM OLANCHA CALIFORNIA TO LAS VEGAS NEVADA TO MOUNT
TRUMBULL ARIZONA. THE GUSTY NORTH WINDS ARE EXPECTED TO SUBSIDE ON
MONDAY.
