AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
800 AM PST TUE NOV 10 2015

.SYNOPSIS...A STORM SYSTEM WILL BRING SHOWERS AND ACCUMULATING
MOUNTAIN SNOW TO PORTIONS OF THE SOUTHERN GREAT BASIN THROUGH THIS
AFTERNOON. COOLER TEMPERATURES CAN BE EXPECTED AREA WIDE ALONG WITH
BREEZY NORTHWEST WINDS BEHIND A COLD FRONT THAT WILL MOVE THROUGH
THE REGION TODAY. DRY WEATHER IS EXPECTED WEDNESDAY ONWARD WITH A
SLOW WARMING TREND BUT TEMPERATURES REMAINING A FEW DEGREES COOLER
THAN NORMAL.
&&

.UPDATE...SENT OUT AN UPDATE TO INCREASE RAIN AND SNOW CHANCES ALONG
A BAND STRETCHING FROM SOUTHEAST INYO COUNTY ACROSS NORTHERN CLARK
AND INTO SOUTHERN LINCOLN COUNTIES. THIS BAND IS MOVING QUICKLY
EASTWARD ASSOCIATED WITH THE COLD FRONT BUT DESERT ROCK DID PICK UP
A QUICK TENTH OF AN INCH SHORTLY BEFORE 7AM. AS FAR AS THE LAS VEGAS
VALLEY GOES...THE COLD FRONT IS CURRENTLY BISECTING THE VALLEY AND
LOCATED ROUGHLY AT MCCARRAN AIRPORT AND SINKING SOUTHWARD. WINDS AT
MCCARRAN HAVE SHIFTED TO THE NORTH IN THE PAST 30 MINUTES. AS FAR AS
SHOWER CHANCES GO...I DID NUDGE POPS UPWARDS SLIGHTLY BUT IT
CONTINUES TO LOOK LIKE PROSPECTS ARE LOW AND MUCH OF THIS POST-
FRONTAL PRECIP BAND WILL FIZZLE AS IT MAKES ITS APPROACH TOWARDS LAS
VEGAS.  NONETHELESS..SCATTERED SHOWERS REMAIN POSSIBLE TODAY.

-OUTLER-

&&

.SHORT TERM...THROUGH THURSDAY NIGHT.

UPPER LOW CURRENTLY SPINNING JUST SOUTH OF SACRAMENTO WILL CONTINUE
TO TRACK SOUTHEAST THROUGH THE DAY AND EVENTUALLY INTO SOUTHWEST
UTAH BY THIS EVENING. SO FAR NONE OF THE WEATHER SENSORS ACROSS
ESMERALDA AND CENTRAL NYE COUNTIES HAVE RECORDED ANY
PRECIPITATION...BUT CURRENT SATELLITE IMAGERY IS SHOWING SOME CLOUD
ENHANCEMENT ACROSS THOSE AREAS AND THE ASOS IN TONOPAH WAS REPORTING
SNOW WITHIN THE PAST HOUR. AS THE LOW CONTINUES TO TRACK SOUTH AND
EAST PRECIPITATION SHOULD STEADLY INCREASE OVER ESMERALDA AND
CENTRAL NYE COUNTIES AND EVENTUALLY LINCOLN COUNTY BY THIS
AFTERNOON. THE WINTER WEATHER ADVISORIES LOOK GOOD FOR THOSE AREAS.
LINCOLN COUNTY CONTINUES TO BE THE AREA WITH THE MOST FAVORABLE
DYNAMICS AND THE HEAVIEST PRECIPITATION LOOKS TO FALL BETWEEN LATE
MORNING AND MID AFTERNOON. IT LOOKS LIKE THE BULK OF OF THE
PRECIPITATION HAS SHIFTED SOUTH AWAY FROM THE SIERRA AND ANY
PRECIPITATION THAT FALLS THROUGH THE DAY SHOULD BE MORE SHOWERY WITH
ONLY LIGHT ACCUMULATIONS. DID GO AHEAD AND CANCEL THE WINTER
WEATHER ADVISORY FOR THE SIERRA.

A COLD FRONT WILL SWEEP ACROSS THE REGION TODAY WITH GUSTY SOUTHWEST
WINDS AHEAD OF THE FRONT AND GUSTY NORTHWEST WINDS BEHIND. GRADIENTS
ACROSS THE WESTERN PORTIONS OF THE MOJAVE DESERT LOOK TO TIGHTEN
FAIRLY SIGNIFICANTLY THIS MORNING AND IT LOOKS LIKE WIDESPREAD WIND
GUSTS OVER 40 MPH LOOK PRETTY GOOD. HAVE GONE AHEAD AND ISSUED A
WIND ADVISORY FOR MUCH OF SAN BERNARDINO COUNTY...MINUS THE CADIZ
BASIN AND THE RIVER ZONES. THE STRONG WINDS ACROSS SAN BERNARDINO
COUNTY SHOULD START TO SUBSIDE DURING THE AFTERNOON AS THE COLD
FRONT MOVE INTO THE AREA...BUT THE MORONGO BASIN COULD BLOW A LITTLE
LONGER AS THEY TEND TO FAVOR A NORTHWEST WIND BEHIND A FRONT.

THE TROUGH IS EXPECTED TO BE EAST OF THE AREA BY THIS EVENING WITH
ONLY THE EASTERN PORTIONS OF LINCOLN AND MOHAVE COUNTIES SEEING ANY
RESIDUAL PRECIPITATION...WHICH SHOULD BE LIGHT. DRIER CONDITIONS
OVERNIGHT WITH NO PRECIPITATION FORECAST ANYWHERE IN THE CWA BY
WEDNESDAY MORNING. DRY NORTHWEST FLOW WILL CONTINUE THROUGH
THURSDAY.

TEMPERATURES WILL COOL ABOUT 10 DEGREES TODAY FROM MONDAYS HIGHS AND
AND REMAIN COOL THROUGH MUCH OF THE WEEK. NEXT CONCERN WILL BE FOR
WEDNESDAY MORNING AS SOME LOCATIONS MAY SEE FREEZING
TEMPERATURES...EVEN PORTIONS OF THE LAS VEGAS VALLEY.

.LONG TERM...FRIDAY THROUGH MONDAY.

ENSEMBLE CLUSTERING IS LESS TIGHT THAN YESTERDAY...SO FORECAST
CONFIDENCE IS REDUCED TO AVERAGE. GOOD AGREEMENT FOR FRIDAY AND
SATURDAY SHOWING THE MAIN STORM TRACK WELL TO OUR NORTH WITH A WEAK
CUTOFF LOW HANGING NEAR THE SOUTHERN CALIFORNIA COAST. THIS WILL
SPELL DRY WEATHER AREAWIDE WITH GUSTY NORTH WINDS DOWN THE COLORADO
RIVER VALLEY. DISAGREEMENTS BEGIN IN EARNEST ON SUNDAY. THE CUTOFF
LOW...WHICH IS SOMEWHAT FARTHER WEST THAN THE MODELS SHOWED
YESTERDAY...BEGINS TO DRIFT EAST IN RESPONSE TO AN UPSTREAM TROUGH
APPROACHING THE WEST COAST. THE LOW DRAWS UP SUBTROPICAL MOISTURE ON
ITS EAST SIDE...WHICH NOW HAS THE POTENTIAL TO AFFECT MOHAVE COUNTY
DUE TO THE FARTHER WEST POSITION OF THE LOW. RAISED SKY COVER
SOMEWHAT AND ALSO RAISED POPS A BIT...BUT KEPT THEM BELOW THE
WEATHER THRESHOLD FOR NOW. THE UPSTREAM TROUGH POSES ITS OWN
PROBLEMS FOR MONDAY. THE GFS AND ECMWF OPERATIONAL RUNS HAVE
ESSENTIALLY FLIP FLOPPED...WITH THE GFS NOW STRONGER AND SLOWER /AND
AS A RESULT WETTER FOR MONDAY/...AND THE ECMWF FASTER AND WEAKER.
WILL MOST LIKELY NEED TO INTRODUCE POPS FOR THIS STORM BY THIS TIME
TOMORROW...BUT WOULD LIKE TO HAVE AT LEAST A LITTLE CONFIDENCE IN
THE BEST GEOGRAPHIC AREA AND TIME FRAME BEFORE DOING SO.
&&

.AVIATION...FOR MCCARRAN...TRICKY FORECAST FOR TODAY. GUSTY
SOUTHWEST WINDS OBSERVED OVERNIGHT WILL CONTINUE AND STRENGTHEN
DURING THE DAY WITH GUSTS 20-30 KTS COMMON. WINDS WILL SLOWLY VEER
TO NORTHWESTERLY DURING THE DAY...BUT THE EXACT TIMING OF THIS IS
UNCERTAIN. CURRENTLY ANTICIPATE NORTHWEST WINDS TO BECOME
ESTABLISHED NEAR SUNSET REMAINING GUSTY POTENTIALLY THROUGH THE
EVENING HOURS BEFORE DIMINISHING AFTER MIDNIGHT. DIRECTIONS MAY
BECOME MORE WESTERLY AGAIN BY DAYBREAK WEDNESDAY AS THE SPEEDS
DIMINISH THOUGH CONFIDENCE IN THIS IS LOW. FEW-SCT CIGS AROUND 6K FT
WITH SCT-BKN CIGS NEAR 10K FT DURING THE AFTERNOON AND EARLY EVENING
ARE ANTICIPATED WITH SKIES RAPIDLY CLEARING OUT IN THE LATE EVENING.
MECHANICAL TURBULENCE IS LIKELY THROUGH LATE EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDY CONDITIONS AT THE TERMINALS TODAY WITH TRANSITION
TO PRIMARILY NORTHERLY OR NORTHWESTERLY FLOW DURING THE DAY.
EXPECTING 25-35 KT GUSTS AT THE TERMINALS DURING THE DAY WITH SPEEDS
AND GUSTS DIMINISHING AFTER DARK. KEPT VCSH IN FOR KBIH AROUND
MIDDAY BUT NOT VERY CONFIDENT OF THIS. SCT-BKN CIGS 8-10K FT AT THE
TERMINALS ARE ANTICIPATED BY LATE MORNING WITH RAPID CLEARING AFTER
DARK. MECHANICAL TURBULENCE DOWNSTREAM OF THE SIERRA AND SPRING
MOUNTAINS IS EXPECTED TODAY WITH SOME MOUNTAIN OBSCURATIONS IN THE
SIERRA AND SOUTHERN GREAT BASIN POSSIBLE.
