AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
900 AM PST SUN DEC 1 2013

.SYNOPSIS...PARTLY CLOUDY SKIES...DRY CONDITIONS AND ABOVE NORMAL
TEMPERATURES ARE EXPECTED TO CONTINUE THROUGH MONDAY. A STRONG LOW
PRESSURE SYSTEM WILL ENVELOP MUCH OF THE WESTERN UNITED STATES
DURING THE MIDDLE TO LATTER HALF OF NEXT WEEK...BRINGING
SIGNIFICANTLY COLDER TEMPERATURES...GUSTY WINDS AND CHANCES FOR RAIN
AND SNOW SHOWERS TO THE REGION.
&&

.UPDATE...SECOND MORNING IN A ROW WE HAVE SEEN SOME LOW CLOUDS
DEVELOP IN FAR NORTHEAST MOHAVE COUNTY. LIKE YESTERDAY THEY SHOULD
DISSIPATE BY LATE MORNING. MADE SOME ADJUSTMENTS TO SKY GRIDS TO
ACCOUNT FOR SHIELD OF HIGH CLOUDS ACROSS SOUTHERN THIRD OF FORECAST
AREA AS WELL. HIGH CLOUDS WILL START TO BE PUSHED BACK SOUTH THIS
AFTERNOON AS A NORTHWEST FLOW ALOFT BECOMES MORE ESTABLISHED. NO
OTHER CHANGES NEEDED AT THIS TIME.
&&

.PREV DISCUSSION...
247 AM PST SUN DEC 1 2013

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...MAINLY JUST MINOR TWEAKS
THROUGH MID-DAY MONDAY. ADJUSTED SKY GRIDS WITH SLIGHTLY BETTER
AGREEMENT BETWEEN MODEL RH FIELDS THIS MORNING. HIGH CLOUDS LOOK TO
CONTINUE TO STREAM ACROSS AT LEAST THE SOUTHERN THIRD OF THE
FORECAST AREA TODAY...GRADUALLY THINNING AND PUSHING SOUTH.
OTHERWISE MOSTLY CLEAR SKIES AND ABOVE NORMAL TEMPERATURES ARE
EXPECTED TODAY AND MONDAY. ALONG THE COLORADO RIVER VALLEY...WIND
GUSTS TO AROUND 30 MPH ARE EXPECTED BETWEEN BULLHEAD CITY AND
NEEDLES THIS AFTERNOON...WITH CALMER CONDITIONS MONDAY.

A MAJOR PATTERN SHIFT WILL BEGIN TO IMPACT THE REGION BEGINNING
MONDAY AFTERNOON AS A SIGNIFICANT TROUGH OF LOW PRESSURE PUSHES
SOUTH FROM THE PACIFIC NORTHWEST. THE FIRST AREA TO FEEL ITS IMPACTS
WILL BE THE SIERRAS AND WHITE MOUNTAINS. A STRONG BAND OF 700MB
WINDS OF 35-55 KTS ARE EXPECTED TO SAG SOUTH BETWEEN 18Z MONDAY AND
12Z TUESDAY. THIS WILL BRING A WINDOW WHERE DOWNSLOPE WINDS WILL BE
POSSIBLE. ON THE PLUS SIDE THIS CROSS BARRIER FLOW WILL BE QUITE
STRONG...BUT ON THE OTHER HAND ITS ORIENTATION WITH RESPECT TO THE
TERRAIN IS SUBOPTIMAL. THIS...COMBINED WITH 625-500MB SHEAR ON THE
ORDER OF 15-25 KTS LEADS TO LOW CONFIDENCE IN THE OCCURRENCE OF
DOWNSLOPE WINDS IN THE OWENS AND FISH LAKE VALLEYS. HOWEVER IF
DOWNSLOPE WINDS DO OCCUR WARNING LEVEL WINDS COULD BE POSSIBLE. WILL
HAVE TO KEEP A CLOSE EYE ON THIS OVER THE NEXT COUPLE DAYS.

AS THE BAND OF 700MB WINDS SHIFTS SOUTH GUSTY WINDS WILL LIKELY
BEGIN TO DEVELOP ACROSS SAN BERNARDINO...SOUTHERN CLARK...AND
CENTRAL MOHAVE COUNTIES DURING THE WEE HOURS OF TUESDAY MORNING. AT
THE SAME TIME CLOUDS WILL BE INCREASING ACROSS THE NORTHERN
COUNTIES...WITH CHANCES FOR SHOWERS JUST BEGINNING TO ENCROACH ON
THE FORECAST AREA BY 12Z TUESDAY.

.LONG TERM...TUESDAY THROUGH WEDNESDAY...STILL LOOKING AT A BIG
CHANGE IN THE PATTERN. A COLD TROUGH IN THE GULF OF ALASKA THIS
MORNING WILL MOVE THROUGH THE PACIFIC NORTHWEST INTO NORTHERN NEVADA
TUESDAY. INCREASED WESTERLY FLOW ALOFT AHEAD OF THE TROUGH WILL KEEP
A CHANCE OF STRONG DOWNSLOPE WINDS GOING ALONG THE EASTERN SIERRA
SLOPES AT LEAST EARLY TUESDAY AND ALSO POSSIBLY DEVELOPING IN THE
SPRING MOUNTAINS. MUCH OF THE MOJAVE DESERT REGION WILL SEE STRONG
GRADIENT/THERMALLY DRIVEN WINDS MUCH OF THE DAY TUESDAY AND WIND
ADVISORIES WILL LIKELY BE NEEDED IN SEVERAL ZONES. A COLD FRONT WILL
WORK SOUTH INTO THE NORTHERN PART OF THE FORECAST AREA TUESDAY
AFTERNOON LEADING TO THE START OF A MAJOR COOLING TREND. IN
ADDITION...PRECIPITATION WILL ALSO BE DEVELOPING ACROSS THE FAR
NORTHERN PART OF THE FORECAST AREA WITH THE BEST CHANCES OVER
NORTHERN LINCOLN COUNTY. PRECIPITATION CHANCES WILL BE SPREADING
ACROSS MUCH OF THE AREA TUESDAY NIGHT AS THE TROUGH AND COLD FRONT
CONTINUE TOWARD THE SOUTHEAST. THE MODELS CONTINUE TO TARGET LINCOLN
AND NORTHERN MOHAVE COUNTIES WITH THE HIGHEST QPF WHICH MAKES SENSE
GIVEN THE TRAJECTORY OF THIS SYSTEM. BASED ON THE GFS/ECMWF/GEM
MODELS THERE IS A GOOD POSSIBILITY OF 3 TO 6 INCHES OF SNOW IN
LINCOLN COUNTY WITH MORE AT THE HIGHER ELEVATIONS...MAINLY FALLING
TUESDAY NIGHT. THE MODELS ARE PRETTY QUICK TO BRING DRIER IN FROM
THE WEST WEDNESDAY WITH PRECIPITATION SHIFTING MAINLY TO EASTERN
LINCOLN COUNTY AND MOHAVE COUNTY BUT SOME LIGHT SHOWERS/FLURRIES
COULD LINGER OVER THE SOUTHERN NEVADA MOUNTAINS AND THE SIERRA. SNOW
LEVELS WILL BE DROPPING QUITE LOW TUESDAY NIGHT AND WEDNESDAY.
FORTUNATELY IT LOOKS LIKE MOISTURE WILL BE PRETTY LIMITED BY THE
TIME SNOW LEVELS DROP TO NEAR THE VALLEY FLOORS IN THE MOJAVE
DESERT. TEMPERATURES BY WEDNESDAY BEHIND THE COLD FRONT WILL BE 10
TO 15 DEGREES BELOW NORMAL ACROSS THE ENTIRE FORECAST AREA.

THURSDAY THROUGH SATURDAY...OVERALL IT LOOKS LIKE THE AREA WILL BE
UNDER A CHILLY AND DRY NORTHWEST FLOW THROUGH THE PERIOD.
TEMPERATURES ARE EXPECTED TO REMAIN AT LEAST 10 TO 15 DEGREES BELOW
NORMAL. SOME AREAS WHICH HAVE NOT YET DIPPED BELOW FREEZING THIS
SEASON MAY DO SO THURSDAY MORNING AND IF NOT THEN...PROBABLY BY
FRIDAY MORNING.
&&

.AVIATION...FOR MCCARRAN...GOOD CONFIDENCE IN LIGHT WINDS FAVORING
TYPICAL DIURNAL TRENDS THRU THE PERIOD. OCCASIONAL CLOUDS AOA
25KFT...MAINLY TO THE SOUTH.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MAINLY LIGHT WINDS FAVORING TYPICAL DIURNAL TRENDS
THRU THE PERIOD. THE EXCEPTION WILL BE ALONG THE COLORADO RIVER
VALLEY WHERE WINDS OF 10-20 KTS AND GUSTS TO 25-30 KTS WILL BE
POSSIBLE BETWEEN KIFP AND KEED TODAY. OCCASIONAL CLOUDS AOA 25K
FEET...MAINLY SOUTH OF LAS VEGAS.
