AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
905 AM PST SAT NOV 22 2014

.SYNOPSIS...A COLD FRONT PUSHING SOUTH ACROSS THE REGION TONIGHT
WILL CAUSE WARM CONDITIONS TODAY TO GIVE WAY TO COOLER AND WINDY
CONDITIONS SUNDAY. THE STRONGEST WINDS WILL OCCUR IN THE SIERRA
TODAY AND ALONG THE COLORADO RIVER VALLEY SUNDAY. CALMER CONDITIONS
ARE EXPECTED MONDAY INTO AT LEAST THANKSGIVING DAY.
&&

.UPDATE...LOW CLOUDS AND SHOWERS WERE SPREADING ACROSS NORTHERN
NEVADA NEAR THE BASE OF A TROUGH SLIDING OVER OREGON. AN AREA OF
LIGHT PRECIPITATION WAS DETECTED OVER CENTRAL CALIFORNIA AND THIS
WILL BRUSH THE SOUTHERN SIERRA BUT WILL PRIMARILY BE INTERCEPTED
WEST OF THE CREST WITH A LITTLE SPILLING OVER ON TO THE EASTERN
SLOPES. THE MAIN STORY FOR OUR AREA WILL BE INCREASING WINDS ACROSS
OUR SOUTHERN SIERRA ZONE THIS AFTERNOON FOLLOWED BY GUSTY NORTHWEST
WINDS DEVELOPING TONIGHT ACROSS MOST OF THE FORECAST AREA. SUSTAINED
NORTH WINDS OVER 25 MPH WILL THEN LIKELY CONCENTRATE ALONG THE
COLORADO RIVER FROM COTTONWOOD COVE TO LAKE HAVASU SUNDAY MORNING
THROUGH LATE SUNDAY AFTERNOON. THE GOING FORECAST HAS THESE
TRENDS COVERED FAIRLY WELL AND NO IMMEDIATE CHANGES ARE NEEDED.
&&

.PREV DISCUSSION...
152 AM PST SAT NOV 22 2014

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...MID AND HIGH LEVEL CLOUDS
CONTINUE TO DRIFT ACROSS THE AREA EARLY THIS MORNING AHEAD OF A FAST
MOVING SHORTWAVE EMBEDDED WITHIN A VERY STRONG [160-170KT] JET OFF
THE COAST OF OREGON/NORCAL. THIS SYSTEM WILL DROP SOUTHEAST ACROSS
THE GREAT BASIN TODAY AND SHOULD MAINLY BRING WINDY CONDITIONS AS
MOISTURE IS FAIRLY LIMITED. THAT SAID...THERE COULD BE SOME SHOWER
ACTIVITY OVER THE SIERRA AS WELL AS NORTHERN LINCOLN COUNTY TODAY.
AS FOR THE WINDS...MODELS ARE IN REASONABLY GOOD AGREEMENT THAT THE
STRONGEST WINDS WILL LIKELY OCCUR BETWEEN ROUGHLY NOON AND 7 PM THIS
EVENING ALONG THE CREST AND EASTERN SLOPES OF THE SIERRA...PRIMARILY
ABOVE 6000 FEET. THE CORE OF THE PEAK WINDS WILL LIKELY MOVE FROM
NORTH TO SOUTH DURING THIS TIME FRAME STAYING JUST AHEAD OF A COLD
FRONT THAT WILL PUSH SOUTH BEGINNING TODAY. A WIND ADVISORY WAS
ISSUED WITH YESTERDAY AFTERNOON`S PACKAGE AND STILL LOOKS GOOD.
WORTH MENTIONING IS THE SLIGHT POSSIBILITY OF ISOLATED WARNING LEVEL
GUSTS [OVER 70 MPH] NEAR THE HIGHER PEAKS...HOWEVER CONFIDENCE IS
LOW AT BEST. IN ANY CASE IT WOULD BE AN UNCOMFORTABLE DAY FOR
OUTDOOR RECREATION IN THE HIGHER ELEVATIONS OF INYO COUNTY.
ELSEWHERE TODAY A FEW AREAS WILL SEE BREEZY TO LOCALLY WINDY
CONDITIONS...PARTICULARLY IN THE WESTERN MOHAVE DESERT. BREEZY TO
WINDY CONDITIONS ARE ALSO EXPECTED TO MATERIALIZE BEHIND A
WELL-DEFINED COLD FRONT THAT WILL PUSH FROM TONOPAH AROUND 00Z SOUTH
TO LAKE HAVASU BY ROUGHLY 12Z. THAT PLACES THE FRONTAL PASSAGE
THROUGH THE LAS VEGAS VALLEY BETWEEN ROUGHLY 06-08Z [JUST BEFORE
MIDNIGHT]. AT THIS JUNCTURE IT APPEARS UNLIKELY THAT WIDESPREAD WIND
HIGHLIGHTS WILL BE NECESSARY WITH THE FRONTAL PASSAGE...HOWEVER BY
SUNDAY MORNING WINDS DOWN THE COLORADO RIVER VALLEY MAY REACH AT
LEAST LAKE WIND ADVISORY LEVELS. WILL LET THE DAY SHIFT TAKE ANOTHER
LOOK AT THIS POTENTIAL THIS AFTERNOON.

WINDS SHOULD SUBSIDE SOMEWHAT MONDAY AS THE PRESSURE GRADIENT BEGINS
TO RELAX AND A RIDGE OF HIGH PRESSURE BEGINS TO PUSH INTO THE
WESTERN STATES FROM THE WEST. BREEZY CONDITIONS ARE STILL LIKELY IN
FAVORED AREAS SUCH AS THE COLORADO RIVER VALLEY.

TEMPERATURES ARE EXPECTED RISE A BIT TODAY BEFORE FALLING 5-10
DEGREES SUNDAY IN THE WAKE OF THE COLD FRONT.

.LONG TERM...TUESDAY THROUGH FRIDAY...WEATHER WILL HAVE NO IMPACT
ON HOLIDAY TRAVEL PLANS FOR THOSE HEADING IN AND OUT OF VEGAS.
STRONG RIDGE ALONG THE WEST COAST TUESDAY PROGGED TO SHIFT INLAND
ACROSS THE GREAT BASIN WEDNESDAY AND THURSDAY. ALL MODELS START TO
BREAKDOWN THE RIDGE ON FRIDAY BUT DISAGREE ON THE STRENGTH/POSITION
OF A TROUGH OVER THE EASTERN PACIFIC. WILL CONTINUE TO UNDERCUT MOS

NORMAL. A NORTH WIND WILL LINGER DOWN THE COLORADO RIVER SOUTH OF
LAKE MOHAVE TUESDAY AND WEDNESDAY THEN LESSEN ON THURSDAY AND
FRIDAY. NO SIGNIFICANT WINDS ARE EXPECTED ELSEWHERE.
&&

.AVIATION...FOR MCCARRAN...LIGHT WINDS MAINLY UNDER 8 KTS FAVORING
TYPICAL DIURNAL TRENDS THROUGH THIS MORNING. AN APPROACHING COLD
FRONT WILL BRING UNSETTLED WIND CONDITIONS LIKELY FAVORING A
SOUTHWESTERLY DIRECTION AT 6-12KTS THIS AFTERNOON AND EVENING BEFORE
THE FRONT PUSHES THE WINDS TO A NORTHWESTERLY DIRECTION BETWEEN
ROUGHLY 06Z-09Z TONIGHT. WINDS BEHIND THE FRONT WILL BE AROUND 10-16
KTS WITH GUSTS 15-25 KTS THROUGH SUNDAY MORNING. WINDS SHOULD THEN
DECREASE SUNDAY AFTERNOON. OUTSIDE OF WINDS NO OPERATIONALLY
SIGNIFICANT CLOUDS/WEATHER IS EXPECTED.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS WILL FAVOR TYPICAL DIURNAL PATTERNS THROUGH THIS
MORNING. THIS AFTERNOON AND EVENING WINDS WILL INCREASE FROM THE
SOUTHWEST TO WEST AT 8-16 KTS WITH GUSTS OF 20-30 KTS. HIGHER WINDS
ARE EXPECTED IN THE MOUNTAINS OF INYO AND ESMERALDA COUNTIES WHERE
GUSTS OVER 45 KTS COULD OCCUR. MOUNTAIN OBSCURATIONS AND AREAS OF
MECHANICAL TURBULENCE ARE POSSIBLE IN/AROUND THE OWENS VALLEY
THROUGH THIS EVENING. A COLD FRONT WILL PRESS ACROSS THE AREA
TONIGHT SHIFTING WINDS TO THE NORTHWEST TO NORTH. WIND GUSTS OF
20-30 KTS CAN BE EXPECTED BEHIND THE FRONT ON SUNDAY ESPECIALLY IN
THE COLORADO RIVER VALLEY FROM KIFP TO KHII.

TYPICAL DIURNAL TRENDS THROUGH THIS MORNING. AN APPROACHING COLD
FRONT WILL BRING UNSETTLED WIND CONDITIONS LIKELY FAVORING A
SOUTHWESTERLY DIRECTION AT 6-12KTS THIS AFTERNOON AND EVENING BEFORE
THE FRONT PUSHES THE WINDS TO A NORTHWESTERLY DIRECTION BETWEEN
ROUGHLY 06Z-09Z TONIGHT. WINDS BEHIND THE FRONT WILL BE AROUND 10-16
KTS WITH GUSTS 15-25 KTS THROUGH SUNDAY MORNING. WINDS SHOULD THEN
DECREASE SUNDAY AFTERNOON. OUTSIDE OF WINDS NO OPERATIONALLY
SIGNIFICANT CLOUDS/WEATHER IS EXPECTED.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS WILL FAVOR TYPICAL DIURNAL PATTERNS THROUGH THIS
MORNING. THIS AFTERNOON AND EVENING WINDS WILL INCREASE FROM THE
SOUTHWEST TO WEST AT 8-16 KTS WITH GUSTS OF 20-30 KTS. HIGHER WINDS
ARE EXPECTED IN THE MOUNTAINS OF INYO AND ESMERALDA COUNTIES WHERE
GUSTS OVER 45 KTS COULD OCCUR. MOUNTAIN OBSCURATIONS AND AREAS OF
MECHANICAL TURBULENCE ARE POSSIBLE IN/AROUND THE OWENS VALLEY
THROUGH THIS EVENING. A COLD FRONT WILL PRESS ACROSS THE AREA
TONIGHT SHIFTING WINDS TO THE NORTHWEST TO NORTH. WIND GUSTS OF
20-30 KTS CAN BE EXPECTED BEHIND THE FRONT ON SUNDAY ESPECIALLY IN
THE COLORADO RIVER VALLEY FROM KIFP TO KHII.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
944 PM PST FRI NOV 21 2014

.SYNOPSIS...A COLD FRONT WILL MOVE ACROSS THE AREA SATURDAY EVENING
THROUGH EARLY SUNDAY MORNING. THIS WILL RESULT IN GUSTY WEST TO
SOUTHWEST WINDS AHEAD OF THE FRONT ON SATURDAY AND GUSTY NORTH WINDS
BEHIND THE FRONT ON SUNDAY. OUTSIDE OF A FEW SNOW SHOWERS IN THE
SOUTHERN SIERRA NEVADA...MAINLY NEAR THE CREST...AND A FEW RAIN AND
SNOW SHOWERS IN FAR NORTHERN LINCOLN COUNTY THIS FRONT WILL PASS THE
AREA DRY. DRY CONDITIONS WITH NEAR SEASONABLE TEMPERATURES ARE
EXPECTED ACROSS THE AREA THROUGH THANKSGIVING DAY.
&&

.UPDATE...A FEW MID AND HIGH LEVEL CLOUDS ARE PUSHING ACROSS THE
REGION FROM THE NORTHWEST THIS EVENING WITH LITTLE IMPACT AT THIS
TIME. I DID ADJUST SKY GRIDS TO REFLECT THE LATEST TRENDS AND SHORT
RANGE GUIDANCE. OTHERWISE THE SHORT TERM FORECAST IS ON TRACK.
&&

.PREV DISCUSSION...
ISSUED 314 PM PST FRI NOV 21 2014

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT.

AS QUICKLY AS ONE SYSTEM HAS EXITED THE AREA ANOTHER SYSTEM IS ABOUT
TO ENTER THE PICTURE. SATELLITE IMAGERY SHOWS PLENTY OF HIGH LEVEL
CLOUDS STARTING TO PUSH ACROSS NORTHERN NEVADA THIS AFTERNOON AND
THESE WILL SPILL SOUTHEAST TONIGHT ON THE LEADING EDGE OF THE NEXT
JET STREAK. THUS EXPECT A PARTLY TO MOSTLY CLOUDY SKY TONIGHT WITH
LOWS A TOUCH HIGHER THAN WHAT WE SAW THIS MORNING.

THE NEXT MID/UPPER LEVEL SHORTWAVE TROUGH IS EXPECTED TO MOVE
SOUTHEAST ACROSS NEVADA TOMORROW AFTERNOON INTO TOMORROW NIGHT
ACCOMPANIED BY A FULL-FLEDGED COLD FRONT PASSAGE AT THE SURFACE. A
POWERHOUSE JET SHOWN BY THE GFS TO EXCEED 160 KTS OVER NORTHEAST
NEVADA AT 250 MB WILL ACCOMPANY THIS TROUGH, HOWEVER, MODELS FAIL TO
REALLY ALIGN THE WINDFIELDS BELOW 700 MB WELL ENOUGH TO ALLOW THE
STRONGEST WINDS TO MIX DOWN TO THE SURFACE. AS A RESULT, WINDS WILL
BE GUSTY STARTING SATURDAY AFTERNOON INTO SATURDAY NIGHT, BUT IN
MOST AREAS THE LACK OF WELL-ALIGNED WINDS WILL CUT DOWN ON THE
STRENGTH OF THEM AT THE SURFACE. THE MAIN EXCEPTION IS ALONG THE
CREST AND IN THE EASTERN SLOPES OF THE SOUTHERN SIERRA NEVADA, WHERE
MODEL CROSS SECTIONS FROM THE ARW AND NMM MODELS BOTH SHOW WINDS
REACHING 50 KTS AT LEAST DOWN TO MID-SLOPE SATURDAY EVENING.
ALTHOUGH THE JET IS STRONG, THE FLOW LACKS A CROSS BARRIER COMPONENT
AND AS A RESULT NO REAL CRITICAL LAYER DEVELOPS. THUS THE THREAT OF
STRONG DOWNSLOPE WINDS INTO THE OWENS VALLEY LOOKS LOW ENOUGH TO
KEEP THEM OUT OF ANY HEADLINES, THOUGH SOME LOCAL GUSTS COULD REACH
OR EXCEED 40 MPH NEAR CANYON OPENINGS. A WIND ADVISORY WAS ISSUED
FOR THE CREST AND EASTERN SLOPES OF THE SOUTHERN SIERRA NEVADA WHERE
SEVERAL HOURS OF WIND GUSTS OF 50-65 MPH SHOULD MATERIALIZE SATURDAY
AFTERNOON AND EVENING. ELSEWHERE GUSTS UP TO 40 MPH WILL BE POSSIBLE
SATURDAY AFTERNOON AND EVENING FROM THE SOUTHWEST. ALTHOUGH MOISTURE
LACKS, ENOUGH MOISTURE IN THE 700-500 MB LAYER (MID-LEVELS) IS SHOWN
TO JUSTIFY A FEW SHOWERS IN THE SOUTHERN SIERRA AND IN NORTHERN
LINCOLN COUNTY FROM SATURDAY MORNING INTO SATURDAY EVENING AHEAD OF
THE FRONT. SNOW LEVELS WILL MAINLY BE ABOVE 9500 FEET.

THE FRONT IS EXPECTED TO PRESS SOUTH ACROSS THE AREA SATURDAY NIGHT
AND GUSTY NORTHWEST TO NORTH WINDS ARE EXPECTED BEHIND IT SATURDAY
NIGHT INTO SUNDAY. THE NORTHWEST PART OF THE LAS VEGAS VALLEY SHOULD
SEE SOME GUSTS TO 35 MPH SATURDAY NIGHT INTO SUNDAY MORNING. WINDS
MAY GET CLOSE TO LAKE WIND ADVISORY CRITERIA SUNDAY MAINLY IN THE
LAUGHLIN-BULLHEAD CITY AREA. DRIER AIR WORKING IN SHOULD END ANY
PRECIPITATION AS WELL AS CLEAR OUT MOST OF THE CLOUDS FOR SUNDAY.

TEMPS SHOULD BE A FEW DEGREES WARMER TOMORROW AND SHOULD TAKE A RUN
AT 70 IN LAS VEGAS. HOWEVER, FORECAST SOUNDINGS SHOW SEVERAL DEGREES
OF COOLING FOR SUNDAY WHICH WILL DROP HIGHS BACK CLOSER TO NORMAL.

.LONG TERM...MONDAY THROUGH FRIDAY NIGHT.

NORTHWEST FLOW ALOFT LINGERS ACROSS THE AREA FROM MONDAY INTO
TUESDAY AS THE AREA SITS BETWEEN A RIDGE OFFSHORE AND A TROUGH OVER
THE INTERMOUNTAIN WEST. FORECAST SOUNDINGS SHOW AN INVERSION BOTH
DAYS BETWEEN 2200 AND 3000 FEET WHICH WILL KEEP THE VALLEYS FROM
WARMING BACK UP QUICKLY INITIALLY. THUS WE HAVE KEPT HIGHS COOLER
THAN WHAT FORECAST SOUNDINGS SUGGEST. BY WEDNESDAY A RIDGE OFFSHORE
IS SLATED TO SHIFT EAST INTO THE SOUTHWEST AND THEN MOVE EAST ON
THANKSGIVING DAY. THIS WILL HELP TO MIX THE LOW-LEVELS BETTER AND
THUS WARM UP TEMPS SEVERAL DEGREES IN THE LOWER/DEEPER VALLEY AREAS
ESPECIALLY BY THANKSGIVING DAY. ANOTHER MID/UPPER LEVEL TROUGH AXIS
IS SHOWN TO MOVE ACROSS THE AREA ON FRIDAY, HOWEVER, AT THIS TIME,
MOISTURE LACKS, THUS THE FORECAST REMAINS DRY. SOME INCREASE
IN CLOUDS AND WIND ARE LIKELY, HOWEVER, NO STRONG WINDS APPEAR TO BE
A THREAT AT THIS TIME.
&&

.AVIATION...FOR MCCARRAN...WINDS ARE EXPECTED TO REMAIN MAINLY UNDER
8 KTS FAVORING TYPICAL DIURNAL TRENDS THROUGH SATURDAY AFTERNOON.
SCT-BKN CLOUDS MAINLY AOA 10 KFT TONIGHT THROUGH SATURDAY MORNING
TRENDING TOWARD FEW-SCT BY SATURDAY AFTERNOON. A COLD FRONT WILL
PASS ACROSS THE LAS VEGAS VALLEY SATURDAY EVENING BETWEEN 06Z AND
10Z AND SHIFT WINDS FROM THE SOUTH TO NORTHWEST. GUSTS TO 25 KTS ARE
POSSIBLE AHEAD OF AND BEHIND THE COLD FRONT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SCT-BKN CLOUDS AOA 20K FEET TONIGHT THROUGH SATURDAY
MORNING NORTH OF A KIYK-KLAS-KSGU LINE TRENDING TOWARD FEW-SCT
SATURDAY AFTERNOON INTO SATURDAY NIGHT. MOUNTAIN OBSCURATIONS ARE
POSSIBLE IN THE OWENS VALLEY SATURDAY MORNING AND AFTERNOON. WINDS
WILL FAVOR TYPICAL DIURNAL PATTERNS THROUGH SATURDAY MORNING.
SATURDAY AFTERNOON INTO SATURDAY EVENING WINDS WILL INCREASE FROM
THE SOUTHWEST TO WEST AT 8-16 KTS WITH GUSTS OF 20-30 KTS. HIGHER

908 AM PST FRI NOV 21 2014

.SYNOPSIS...A WEAKENING PACIFIC STORM SYSTEM WILL BRING CLOUDY SKIES
AND A FEW AREAS OF SHOWERS THROUGH THIS MORNING. CONDITIONS ARE
EXPECTED TO IMPROVE AREAWIDE BY THE AFTERNOON. A SECOND SYSTEM WILL
BRING GUSTY WINDS TO PORTIONS OF THE SOUTHERN GREAT BASIN AND
MOJAVE DESERT SATURDAY AND SUNDAY.
&&

.UPDATE...THROUGH TONIGHT.

I WENT AHEAD AND MADE SOME FURTHER ADJUSTMENTS TO THE FORECAST FOR
TODAY. THE MID/UPPER LEVEL LOW HAS MOVED FAR ENOUGH TO THE SOUTH
THAT ALL SIGNS POINT TOWARD THIS EVENT BEING DONE AND OVER FOR OUR
AREA. A FEW LOCATIONS DID REPORT RAINFALL THIS MORNING IN THE
MORONGO BASIN WITH A TRACE REPORTED AT JOSHUA TREE AND YUCCA VALLEY
AND 0.03 INCH REPORTED AT MORONGO VALLEY. A FEW SPOTS IN SOUTHEAST
MOHAVE COUNTY NEAR WIKIEUP MAY STILL SEE A FEW SPRINKLES BASED ON
THE LATEST RADAR, HOWEVER, ALL SIGNS POINT TOWARD A RAPID DRYING OF
THE ATMOSPHERE AS PLENTY OF DRY AIR HAS WORKED INTO THE AREA ON THE
NORTH AND WEST SIDE OF THE LOW. AS A RESULT, I DECREASED POPS
FURTHER, REMOVING THEM FROM ALL BUT A SMALL AREA OF SOUTHEAST MOHAVE
COUNTY FOR THIS MORNING, AND DECREASED CLOUD COVER THIS MORNING
SIGNIFICANTLY AWAY FROM MOHAVE COUNTY. I ALSO WENT AHEAD AND LOWERED
DEWPOINTS FOR THIS AFTERNOON AS MANY AREAS WERE ALREADY BELOW
FORECAST VALUES FOR THIS PERIOD.

ANOTHER BATCH OF HIGH CLOUDS SHOULD WORK INTO THE AREA THIS
AFTERNOON INTO TONIGHT FROM THE NORTHWEST IN ASSOCIATION WITH THE
NEXT JET STREAK MOVING INTO SOUTHERN OREGON AND NORCAL. THIS WILL
BRING BACK PARTLY TO MOSTLY CLOUDY CONDITIONS FOR TONIGHT.
&&

.AVIATION...FOR MCCARRAN...WINDS ARE EXPECTED TO REMAIN MAINLY UNDER

.PREVIOUS DISCUSSION...
ISSUED AT 438 AM PDT FRI NOV 21 2014

.SHORT TERM...SATURDAY THROUGH SUNDAY NIGHT...THE NEXT SHORTWAVE IS
EXPECTED TO BRUSH THE GREAT BASIN LATE SATURDAY THROUGH SUNDAY
MORNING. THIS WAVE WILL BRING ADDITIONAL CHANCES FOR PRECIPITATION
FOR THE NORTHERN PORTIONS OF INYO...ESMERALDA...NYE AND LINCOLN
COUNTIES SATURDAY AND SATURDAY NIGHT. ONE POINT OF CONCERN ARE WINDS
ACROSS THE SIERRA SATURDAY AFTERNOON/EVENING AND THE POTENTIAL FOR A
BRIEF PERIOD OF DOWNSLOPE WINDS. WHILE THE DOWNSLOPE SIGNATURE ISN`T
ALL THAT IMPRESSIVE... LOCAL HIGH RESOLUTION GUIDANCE DOES INDICATE
THAT WINDS COULD REACH ADVISORY [GUSTS OVER 58 MPH] OR EVEN WARNING
[GUSTS OVER 70 MPH] LEVELS DURING THIS TIMEFRAME...PRIMARILY ABOVE
6000 FEET. WE WILL CONTINUE TO MONITOR THIS SITUATION OVER THE NEXT
12-24 HOURS AND MAY NEED TO ISSUE WIND HIGHLIGHTS. THIS SYSTEM WILL
ALSO BRING A DECENT PUSH OF NORTHERLY WINDS ACROSS THE AREA
SUNDAY...WITH THE STRONGEST WINDS LIKELY ACROSS FAVORED AREAS SUCH
AS CENTRAL NYE COUNTY AND THE COLORADO RIVER VALLEY.

TEMPERATURES ARE EXPECTED TO BE AROUND TO SLIGHTLY ABOVE NORMAL
THROUGH THE SHORT TERM PERIOD...TRANSLATING INTO THE MID-UPPER 60`S
FOR THE LAS VEGAS VALLEY.

.LONG TERM...MONDAY THROUGH THURSDAY...A FINAL SHORTWAVE WILL BE
MOVING THROUGH THE FOUR CORNERS REGION MONDAY. THE SYSTEM LOOKS TO
BE DRY FOR LINCOLN AND MOHAVE COUNTIES BUT WILL BRING A CONTINUATION
OF BRISK NORTH WINDS, ESPECIALLY TO THE COLORADO RIVER VALLEY SOUTH
OF LAKE MOHAVE. TEMPERATURES WILL BE IN THE UPPER 40S TO LOWER 50S
FROM GOLDFIELD EAST TO CALIENTE. FOR THE MOJAVE DESERT HIGHS WILL
RANGE FROM THE UPPER 50S TO MID 60S.

00Z MODELS HAVE COME INTO GOOD AGREEMENT DEVELOPING A STRONG RIDGE
OVER THE AREA TUESDAY/WEDNESDAY WITH RIDGE STARTING TO FLATTEN/BREAK
DOWN ON THANKSGIVING DAY. BOTH THE GFS/EC MOS GUIDANCE SHOW HIGHS
FOR LAS VEGAS ON WEDNESDAY/THANKSGIVING DAY AROUND 70. AS VALLEY
INVERSIONS STRENGTHEN OVER TIME CHALLENGE WILL BECOME FORECASTING
HIGH TEMPERATURES AND FOR NOW UNDERCUTTING THOSE VALUES BY SEVERAL
DEGREES. A NORTH BREEZE WILL LINGER DOWN THE RIVER VALLEY THROUGH
WEDNESDAY BUT SHOULD WEAKEN FOR THANKSGIVING DAY FOR THOSE LOOKING
TO RECREATE ON THE LAKES.

NATIONAL WEATHER SERVICE LAS VEGAS NV
438 AM PST FRI NOV 21 2014

.SYNOPSIS...A WEAKENING PACIFIC STORM SYSTEM WILL BRING CLOUDY SKIES
AND A FEW AREAS OF SHOWERS THROUGH THIS MORNING. CONDITIONS ARE
EXPECTED TO IMPROVE AREAWIDE BY THE AFTERNOON. A SECOND SYSTEM WILL
BRING GUSTY WINDS TO PORTIONS OF THE SOUTHERN GREAT BASIN AND
MOJAVE DESERT SATURDAY AND SUNDAY.
&&

.UPDATE...SCATTERED SHOWERS/THUNDERSTORMS OCCURRING IN SOUTHWEST SAN
BERNARDINO COUNTY AND WESTERN RIVERSIDE COUNTY UNDER CORE OF
SHORTWAVE. SHORTWAVE PROGGED TO SLIDE SOUTHEAST TOWARD YUMA THROUGH
THE REST OF THIS MORNING. SATELLITE SHOWS CLOUD TOPS WARMING AND
DISSIPATING ACROSS SOUTHERN NEVADA SO RAIN CHANCES NOT LOOKING GOOD
AROUND HERE SO HAVE LOWERED POPS.
&&

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT...MID AND HIGH LEVEL CLOUDS
HAVE BEEN WIDESPREAD ACROSS THE REGION OVERNIGHT. HOWEVER
PRECIPITATION AND LOW CLOUD DECKS HAVE BEEN HARD TO COME BY. AS OF
10Z THERE WAS SOME PRECIPITATION AND EVEN A COUPLE WEAK
THUNDERSTORMS BEGINNING TO WANDER THROUGH SOUTHWESTERN SAN
BERNARDINO COUNTY AND THE HRRR HAS HAD THE BEST HANDLE ON THIS OVER
THE LAST COUPLE HOURS. THIS AREA OF PRECIPITATION IS ASSOCIATED WITH
AN UPPER LEVEL LOW CIRCULATION THAT WAS CENTERED JUST NORTH OF
BARSTOW. THIS LOW WILL PUSH SOUTHEAST TOWARDS YUMA AND FAR SOUTHERN
ARIZONA AS THE DAY GOES ON. THE MOST RECENT MODELS HAVE TRENDED MUCH
DRIER FOR THIS MORNING AND PRECIPITATION CHANCES WERE REDUCED ACROSS
THE BOARD. FOR LAS VEGAS I DID LEAVE IN A SLIGHT CHANCE OF
PRECIPITATION...WITH THE BEST CHANCES BETWEEN 4AM AND 8AM THIS
MORNING. IT`S BECOMING INCREASINGLY LIKELY THAT THERE WILL JUST BE A
FEW VIRGA SHOWERS AROUND THE VALLEY NEAR SUNRISE. PRECIPITATION
CHANCES LOOK TO END ACROSS THE FORECAST AREA BY 18Z AND POPS WERE
REMOVED FOR THIS AFTERNOON. EXPECT THE SUN TO COME OUT ACROSS MOST
OF THE REGION THIS AFTERNOON.

THE NEXT SHORTWAVE IS EXPECTED TO BRUSH THE GREAT BASIN LATE
SATURDAY THROUGH SUNDAY MORNING. THIS WAVE WILL BRING ADDITIONAL
CHANCES FOR PRECIPITATION FOR THE NORTHERN PORTIONS OF
INYO...ESMERALDA...NYE AND LINCOLN COUNTIES SATURDAY AND SATURDAY
NIGHT. ONE POINT OF CONCERN ARE WINDS ACROSS THE SIERRA SATURDAY
AFTERNOON/EVENING AND THE POTENTIAL FOR A BRIEF PERIOD OF DOWNSLOPE
WINDS. WHILE THE DOWNSLOPE SIGNATURE ISN`T ALL THAT IMPRESSIVE...
LOCAL HIGH RESOLUTION GUIDANCE DOES INDICATE THAT WINDS COULD REACH
ADVISORY [GUSTS OVER 58 MPH] OR EVEN WARNING [GUSTS OVER 70 MPH]
LEVELS DURING THIS TIMEFRAME...PRIMARILY ABOVE 6000 FEET. WE WILL
CONTINUE TO MONITOR THIS SITUATION OVER THE NEXT 12-24 HOURS AND MAY
NEED TO ISSUE WIND HIGHLIGHTS. THIS SYSTEM WILL ALSO BRING A DECENT
PUSH OF NORTHERLY WINDS ACROSS THE AREA SUNDAY...WITH THE STRONGEST
WINDS LIKELY ACROSS FAVORED AREAS SUCH AS CENTRAL NYE COUNTY AND THE
COLORADO RIVER VALLEY.

TEMPERATURES ARE EXPECTED TO BE AROUND TO SLIGHTLY ABOVE NORMAL
THROUGH THE SHORT TERM PERIOD...TRANSLATING INTO THE MID-UPPER 60`S
FOR THE LAS VEGAS VALLEY.

.LONG TERM...MONDAY THROUGH THURSDAY...A FINAL SHORTWAVE WILL BE
MOVING THROUGH THE FOUR CORNERS REGION MONDAY. THE SYSTEM LOOKS TO
BE DRY FOR LINCOLN AND MOHAVE COUNTIES BUT WILL BRING A CONTINUATION
OF BRISK NORTH WINDS, ESPECIALLY TO THE COLORADO RIVER VALLEY SOUTH
OF LAKE MOHAVE. TEMPERATURES WILL BE IN THE UPPER 40S TO LOWER 50S
FROM GOLDFIELD EAST TO CALIENTE. FOR THE MOJAVE DESERT HIGHS WILL
RANGE FROM THE UPPER 50S TO MID 60S.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
246 PM PST THU NOV 20 2014

.SYNOPSIS...
A PACIFIC STORM SYSTEM WILL BRING LIGHT MOUNTAIN SNOW
AND VALLEY RAIN ACROSS THE AREA TONIGHT AND FRIDAY.  AFTER THE STORM
SYSTEM EXITS THE AREA...DRY CONDITIONS WITH TEMPERATURES NEAR NORMAL
ARE EXPECTED TO PERSIST INTO MID WEEK.

&&

.SHORT TERM...ONIGHT THROUGH SATURDAY NIGHT...
HIGH CLOUDS HAVE MOVED IN OVER MUCH OF THE AREA AHEAD OF AN
APPROACHING PACIFIC STORM SYSTEM.  THIS STORM WILL BRING VALLEY RAIN
AND LIGHT MOUNTAIN SNOW THIS EVENING THROUGH TOMORROW.  SNOW LEVELS
WILL FALL TO BELOW 6500 FEET WITH AN INCH OR TWO OF NEW SNOW
EXPECTED ON THE EASTERN SLOPES OF THE SIERRA AS WELL AS THE SPRING
MOUNTAINS AND SHEEP RANGE.  ANOTHER PACIFIC TROUGH WILL MOVE ASHORE
SATURDAY BUT WILL REMAIN WELL NORTH OF OUR AREA.  THIS SYSTEM MAY
DELIVER A GLANCING BLOW BY BRINGING A LITTLE PRECIPITATION TO
NORTHERN LINCOLN COUNTY SATURDAY AFTERNOON THROUGH EARLY SUNDAY
MORNING.  ELSEWHERE...THIS SYSTEM WILL BRING BREEZY TO WINDY
CONDITIONS WITH NORTH WIND GUSTING OVER 30 MPH MAINLY DOWN THE
COLORADO RIVER VALLEY.

.LONG TERM...SUNDAY THROUGH WEDNESDAY...
GUSTY WIND REMAINS THROUGH SUNDAY AS A COLD FRONT MOVES THROUGH THE
AREA. DRY NORTHWEST FLOW ALOFT WILL FOLLOW AS A RIDGE OF HIGH
PRESSURE BUILDS OVER THE EASTERN PACIFIC AND SLOWLY TRANSLATED
EASTWARD.  THIS WILL KEEP THE FORECAST AREA DRY WITH TEMPERATURES
NEAR CLIMATOLOGICAL NORMAL THROUGH MID WEEK.  THERE HAS BEEN SOME
MODEL DISCREPANCY OVER WHETHER A STORM SYSTEM DEVELOPING OVER THE
AREA BY WEDNESDAY BUT RECENT MODEL TRENDS INDICATE THAT A
STORM...IF ANY...WOULD LIKELY OCCUR LATER IN THE WEEK.  STAY TUNED
FOR FURTHER UPDATES.

&&

.AVIATION...OR MCCARRAN...
BKN-OVC CIGS TO PERSIST THROUGH 18Z
FRIDAY AS A PACIFIC STORM SYSTEM MOVES THROUGH. PERIODS OF -SHRA

BUILD IN TODAY RESULTING IN MOSTLY SUNNY SKIES AND TEMPERATURES
SLIGHTLY WARMER THAN OBSERVED WEDNESDAY.  BY LATER IN THE AFTERNOON
HIGH CLOUDS IN ADVANCE OF THE NEXT STORM SYSTEM WILL OVERSPREAD THE
REGION WITH RAIN AND MOUNTAIN SNOW SHOWERS DEVELOPING ACROSS OUR
NORTHWESTERN ZONES FROM THE SIERRA CREST EASTWARD INTO ESMERALDA
COUNTY.  AS THE SYSTEM MOVES OVERHEAD FRIDAY MORNING RAIN AND

FEET.

THE CLOSED LOW RESPONSIBLE FOR THE UNSETTLED WEATHER WILL BE A QUICK
MOVER AND BE EXITING OUR REGION TO THE EAST BY FRIDAY EVENING WITH

SHOW UP IN THE MODELS BEGINNING WEDNESDAY WITH THE GFS INDICATING AN

ECMWF BRINGS A DROPS A SHORTWAVE TROUGH SOUTH THROUGH THE PACIFIC

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE LAS VEGAS NV
810 PM PST WED NOV 19 2014

.SYNOPSIS...SCATTERED RAIN AND MOUNTAIN SNOW SHOWERS ARE EXPECTED TO
IMPACT THE AREA THURSDAY NIGHT INTO FRIDAY. SNOW LEVELS WILL DROP TO
6000 FEET WITH LIGHT ACCUMULATIONS ABOVE THAT LEVEL. PRECIPITATION
CHANCES DROP OVER THE WEEKEND WITH TEMPERATURES THROUGH THE WEEK
AT OR JUST BELOW NORMAL INTO EARLY NEXT WEEK.
&&

.UPDATE...SKIES ARE CLEARING OUT THIS EVENING WITH JUST SOME
LINGERING CLOUDS ACROSS LINCOLN AND MOHAVE COUNTIES. EXPECT TO SEE
CONTINUED CLEARING TONIGHT AND NO UPDATES ARE NEEDED.

&&

.SHORT TERM...
TONIGHT THROUGH FRIDAY NIGHT...ANOTHER UPPER LEVEL LOW PRESSURE
SYSTEM WILL MOVE IN FROM THE NORTHWEST ON THURSDAY NIGHT INTO
FRIDAY. SNOW LEVELS ARE EXPECTED TO DROP DOWN TO 6KFT AS THE CENTER
OF THE LOW PASSES OVERHEAD. INSTABILITY WITH COLD CORE ALOFT WILL
GENERATE SHOWER ACTIVITY ACROSS MOST OF THE FORECAST AREA. IT IS
LIKELY WE MAY SEE SNOW BURSTING DOWN TO LEVELS BELOW 6KFT. IN MOST
CASES ACCUMULATIONS WILL BE LIGHT AS SHOWERS WILL BE SHORT LIVED. IN
LIKE THE SYSTEM THAT PASSED OUR AREA TODAY (WEDNESDAY) THIS SECOND
SYSTEM MAY BRING ABOUT LIGHT SHOWERS DOWN TO THE VALLEY LEVEL. GIVEN
THE LONG PERIOD OF TIME SINCE OUR LAST RAINFALL...THIS MAY BRING
ABOUT A TRICKY MORNING COMMUTE ON FRIDAY AS ROADS MAY BE SLICK.

.LONG TERM...
SATURDAY THROUGH TUESDAY...NEARLY ZONAL FLOW WILL BE
OVER THE AREA SATURDAY INTO SATURDAY NIGHT. A WEAK SHORTWAVE MOVING
ACROSS THE NORTHERN GREAT BASIN WILL BRING A SLIGHT CHANCE OF
SHOWERS TO THE FAR NORTHERN PART OF THE FORECAST AREA WITH THE BEST
CHANCE IN NORTHEAST LINCOLN COUNTY. PRECIPITATION AMOUNTS WILL
REMAIN RATHER LIGHT. LOOKING AT A DRY NORTHWEST FLOW ALOFT
PERSISTING OVER THE AREA FROM LATE SATURDAY NIGHT THROUGH TUESDAY
BASED ON THE GFS AND ECMWF WITH SOME LOCALLY BREEZY NORTH/NORTHWEST
WINDS AT TIMES. NO SIGNIFICANT TEMPERATURE TRENDS ARE EXPECTED IN
THE LONG TERM PERIOD.
&&

.AVIATION...FOR MCCARRAN...LIGHT WINDS WITH THE TYPICAL DAY/NIGHT
DIRECTIONAL SHIFT WILL EXPECTED TO OCCUR TONIGHT INTO TOMORROW. LATE
THURSDAY...A STORM SYSTEM MOVING IN MAY BRING LIGHT SHOWERS TO THE
LV VALLEY. THERE REMAINS A GOOD CHANCE THAT CEILINGS WILL DROP TO
THE 5KFT THRESHOLD OVERNIGHT INTO FRIDAY. MORE DETAILS WILL BE
AVAILABLE AS THE SYSTEM GETS CLOSER.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A WEAK DISTURBANCE MAY BRING SOME LIGHT SHOWERS TO THE
HIGHER ELEVATIONS OF THE SIERRA THIS AFTERNOON...BUT LITTLE
ELSEWHERE.
