AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
957 PM PST WED DEC 23 2015

.SYNOPSIS...WINDS WILL INCREASE THURSDAY AFTERNOON AHEAD OF A STRONG
COLD AREA OF LOW PRESSURE THAT WILL MOVE INTO THE REGION THURSDAY
NIGHT. THIS SYSTEM WILL CROSS THE AREA THURSDAY NIGHT INTO FRIDAY
MORNING BRINGING A BAND OF PRECIPITATION WITH IT WITH SNOW POSSIBLE
IN SOME AREAS AS LOW AS 3000 FEET. COLD AND GUSTY NORTHWEST TO NORTH
WINDS WILL DEVELOP DURING THE DAY FRIDAY AND LAST THROUGH THE
WEEKEND.
&&

.UPDATE...A BATCH OF EXTENSIVE MID-LEVEL CLOUDS HAS DEVELOPED IN THE
LAST FEW HOURS AND SPREAD EAST ACROSS MUCH OF CLARK AND SOUTHERN
LINCOLN COUNTIES FROM SOUTHERN NYE COUNTY (LIKELY GETTING ENHANCED
OFF THE SPRING MOUNTAINS BY STRONGER WINDS ALOFT). I WENT AHEAD AND
ADJUSTED UP SKY COVER TO ACCOUNT FOR THIS TREND AS FORECAST
SOUNDINGS SHOW ENOUGH MOISTURE STICKING AROUND 700 MB OVER LAS VEGAS
FOR MUCH OF THE NIGHT. HOURLY DEWPOINTS WERE ALSO TWEAKED A BIT TO
BRING THEM IN-LINE WITH THE LATEST OBSERVATIONS.
&&

.AVIATION...FOR MCCARRAN...ROBUST NORTHEAST WINDS OF 8-15 KTS WILL
CONTINUE FOR THE NEXT 2-3 HOURS THEN SHOULD DROP OFF AND SWITCH TO
MORE OF A SOUTHWEST TO WESTERLY DIRECTION AT 4-8 KTS. THIS MAY CAUSE
SOME CONFIGURATION ISSUES AT TIMES. CHRISTMAS EVE SHOULD SEE TYPICAL
NORTHEAST TO EAST WINDS AT 4-8 KTS IN THE LATE MORNING AND EARLY
AFTERNOON THEN WINDS SHOULD PICK UP FROM THE SOUTH AROUND 22Z AND
INCREASE TO 10-20 KTS WITH GUSTS OF 20-30 KTS. WINDS SHOULD GET
STRONGER AS WE MOVE INTO THE EVENING. LOW-LEVEL WIND SHEAR IS
POSSIBLE IN THE MORNING DUE TO CHANGES IN WIND DIRECTION WITH HEIGHT
AND INCREASING WINDS ALOFT FROM THE SOUTHWEST. MECHANICAL TURBULENCE
WILL BE POSSIBLE IN THE EVENING HOURS DUE TO STRONGER WINDS ALOFT.
MAINLY SCT-BKN CLOUDS OVERNIGHT AOA 6-9K FEET THEN THESE SHOULD
DISSIPATE BY DAYBREAK OR SHORTLY AFTER. SCT-BKN CLOUDS AOA 18K FEET
CHRISTMAS EVE. BASES WILL LOWER CHRISTMAS EVE NIGHT WITH THE
POTENTIAL FOR SHOWERS BETWEEN 10Z AND 15Z ON CHRISTMAS WHICH SHOULD
BE RAIN AT THE AIRPORT. MOUNTAIN OBSCURATIONS ARE LIKELY THEN.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...OUTSIDE OF CALIFORNIA EXPECT MAINLY FAIR WEATHER WITH
LIGHT WINDS FOLLOWING DIURNAL TRENDS THROUGH THURSDAY MORNING EXCEPT
AROUND KDAG. BY TOMORROW AFTERNOON SOUTHWEST WINDS WILL OVERSPREAD
THE ENTIRE AREA...ESPECIALLY ALONG A BROAD BELT FROM THE WESTERN
MOJAVE DESERT INTO NORTHWEST ARIZONA WHERE GUSTS TO 30 KTS WILL BE
POSSIBLE. EVEN STRONGER WINDS ARE IN STORE FOR THE SIERRA AND
WESTERN MOJAVE DESERT THURSDAY NIGHT. MECHANICAL TURBULENCE ALOFT IS
POSSIBLE. SHOWERS WILL PUSH SOUTH STARTING IN THE AFTERNOON BETWEEN
20Z AND 22Z INTO KBIH WITH CIGS DROPPING TO 1-3K FEET AT LEAST. RAIN
WILL CHANGE OVER TO SNOW AS LOW AS 3K FEET OR SO. MOUNTAIN
OBSCURATIONS ARE LIKELY ALONG WITH MVFR TO IFR VSBY AND LOCAL LIFR
IN ANY SNOW. THIS BAND OF SHOWERS WILL PUSH SOUTHEAST AS THE NIGHT
PROGRESSES IMPACTING AREAS MAINLY NORTHEAST OF A LINE FROM KBIH-
KLAS-KIGM FOR 2-6 HOURS.
&&

.PREVIOUS UPDATE...
ISSUED AT 656 PM PST WED DEC 23 2015

.UPDATE...HIGH CLOUDS ARE COVERING MUCH OF THE SOUTHERN HALF OF THE
AREA AS A RESULT OF MOUNTAIN WAVE ACTIVITY OFF THE TEHACHAPIS. I
WENT AHEAD AND BUMPED UP SKY COVER ACROSS THIS PART OF THE AREA TO
BRING IT MORE IN-LINE WITH SATELLITE IMAGERY. OTHERWISE THE FORECAST
LOOKS IN GOOD SHAPE.
&&

.PREVIOUS DISCUSSION...
ISSUED AT 240 PM PST WED DEC 23 2015

.SHORT TERM...THROUGH SATURDAY NIGHT.

FAIRLY QUIET DAY ACROSS THE REGION TODAY EXPECT FOR WESTERN SAN
BERNARDINO COUNTY WHERE WINDS HAVE BEEN GUSTY ALL DAY. THERE HAS
BEEN SOME DECREASE IN WINDS EARLY THIS AFTERNOON...BUT STILL
CONTINUE TO GUST CLOSE TO 40 MPH. HIRES MODELS AND SURFACE GRADIENTS
CONTINUE TO INDICATE THAT THESE WINDS WILL GRADUALLY DECREASE DURING
THE AFTERNOON. ELSEWHERE...SKIES HAVE BEEN PARTLY TO MOSTLY SUNNY
WITH THE EXCEPTION OF AREAS IN MOHAVE COUNTY AND NORTHERN LINCOLN
COUNTY WHERE LOW CLOUDS HAVE BEEN HANGING AROUND ALL DAY...ALTHOUGH
THERE ARE MORE BREAKS IN THOSE CLOUDS. STILL POSSIBLE TO SEE A LIGHT
SHOWER OR TWO INTO THE EVENING...BUT IF ANYTHING DOES FALL IT WILL
REMAIN LIGHT.

THE FLOW WILL BEGIN TO TURN MORE WESTERLY OVER THE NEXT 12 HOURS AS
A STRONG COLD AREA OF LOW PRESSURE BEGINS TO DIVE DOWN THE WEST
COAST. THE MODELS INDICATE A 130 KT+ JET PUSHING INTO CENTRAL
CALIFORNIA THURSDAY MORNING WHICH WOULD BRING MORE OF A CROSS
BARRIER WIND FLOW INTO THE SOUTHERN SIERRA. THE MODELS ARE NOT
INDICATING ANY SIGNIFICANT DOWNSLOPE FOR THE EASTERN SIERRA
SLOPES...BUT THERE COULD BE A BRIEF PERIOD OF GUSTY WINDS AT THE MID
AND UPPER SLOPES. THE JET IS EXPECTED TO PUSH SOUTH DURING THE DAY
AND IS FORECAST TO BE RIGHT OVER SOUTHERN NEVADA AND SOUTHEAST
CALIFORNIA BY 00Z FRIDAY. I THINK THAT WINDS WILL INCREASE DURING
THE AFTERNOON ACROSS THE DESERT LOCATIONS...BUT CURRENT THINKING IS
THAT THE STRONGEST WINDS WILL OCCUR DURING THE EVENING HOURS AHEAD
OF A STRONG COLD FRONT THAT WILL MOVE THROUGH THE REGION OVERNIGHT.
I HAVE DELAYED THE START TIME OF THE HIGH WIND WATCH TO 6PM. ITS
POSSIBLE THAT EITHER THE WATCH COULD BE EXPANDED TO INCLUDE MORE
AREAS SUCH AS SOUTHERN NEVADA AND EASTERN SAN BERNARDINO COUNTIES OR
ADVISORIES ADDED...BUT WILL LET THE MIDNIGHT SHIFT TAKE ANOTHER
LOOK.

PRECIPITATION LOOKS TO SPREAD INTO THE SIERRA AFTER 18Z THURSDAY AND
THEN INTO THE FAR NORTHERN AREAS OF THE CWA BY LATE AFTERNOON. MUCH
OF THE PRECIPITATION IS INITIALLY EXPECTED TO BE INTERCEPTED BY THE
SIERRA...BUT AS THE COLD FRONT BEGINS TO MOVE SOUTH SO WILL THE
PRECIPITATION. THE COLD FRONT LOOKS TO MOVE INTO THE NORTHERN
PORTIONS OF THE CWA BETWEEN 6PM-10PM THURSDAY EVENING AND INTO
SOUTHERN NEVADA BY EARLY FRIDAY MORNING. THE MODELS CONTINUE TO SHOW
FAVORABLE FRONTOGENESIS ACROSS LINCOLN COUNTY WHERE BURSTS OF
HEAVIER SNOW COULD OCCUR WITH THE FRONT. THERE SHOULD ALSO BE ENOUGH
COLD AIR IN PLACE FOR A FEW INCHES OF ACCUMULATIONS. THE CURRENT
WINTER WEATHER ADVISORY LOOKS GOOD. ANOTHER AREA OF CONCERN FOR SNOW
ACCUMULATIONS IMPACTS IS NORTHERN MOHAVE COUNTY. TOUGH CALL RIGHT
NOW TO DETERMINE IF SNOW LEVELS COULD BE LOW ENOUGH TO IMPACT THE
VIRGIN RIVER GORGE...BUT AREAS SUCH AS COLORADO CITY AND PIPE SPRING
SHOULD BE HIGH ENOUGH. WENT AHEAD AND ADDED A WINTER WEATHER
ADVISORY FOR NORTHERN MOHAVE COUNTY WHICH WILL RUN FROM 10 PM
THURSDAY UNTIL 10 AM FRIDAY. THERE IS STILL A POSSIBILITY THAT
ISOLATED SNOW SHOWERS COULD OCCUR JUST BEHIND THE FRONT AS IT MOVES
THROUGH THE REGION OVERNIGHT. WOULD NOT BE SURPRISED IF PARTS OF THE
LAS VEGAS VALLEY SEES A FEW FLURRIES OVERNIGHT. AS THE COLD POOL
MOVES OVERHEAD FRIDAY THERE COULD ALSO BE ENOUGH DYNAMICS TO WRING
OUT ANY AVAILABLE MOISTURE TO BRING ISOLATED SNOW SHOWERS TO THE
AREA MOUNTAINS THROUGH THE DAY.

GUSTY NORTH WINDS WILL OCCUR BEHIND THE FRONT ON FRIDAY WHICH WILL
BRING IN RATHER CHILLY AIR INTO THE REGION. HIGHS WILL DROP ABOUT 10
DEGREES FROM THURSDAYS HIGHS AND WITH THE WIND IT WILL CERTAINLY
FEEL LIKE WINTER. STRONG WINDS WILL ALSO BE A POSSIBILITY DOWN THE
COLORADO RIVER VALLEY WHERE WINDS MAY BE HIGH ENOUGH TO WARRANT
EITHER A WIND ADVISORY OR POSSIBLY A HIGH WIND WATCH. THE LOW CENTER
WILL PUSH EAST SUNDAY...BUT WE SHOULD STILL SEE GUSTY NORTH WINDS
THROUGH THE DAY. IT DOES LOOK LIKE WINDS WILL DIMINISH SATURDAY
NIGHT WHICH MAY LEAD TO A VERY COLD SUNDAY MORNING. POSSIBLE WE
COULD SEE A LARGE AREA OF TEMPERATURES WELL BELOW FREEZING ACROSS
THE REGION.

.LONG TERM...SUNDAY THROUGH WEDNESDAY.

AFTER A VERY COLD START TO THE DAY SUNDAY...IT LOOKS LIKE FAIRLY
PLEASANT WEATHER IS ON TAP FOR THE EXTENDED PERIOD WITH A GRADUAL
WARMING TREND. VERY COLD AIR WILL BE ENTRENCHED ACROSS OUR AREA
SUNDAY MORNING WITH LOW TEMPERATURES NEAR OR BELOW FREEZING ACROSS
JUST ABOUT THE WHOLE AREA. SOME GUSTY NORTH WINDS WILL PERSIST DOWN
THE COLORADO RIVER SUNDAY BUT SHOULD BE TAPERING OFF BY LATER IN THE
DAY. MONDAY MORNING LOW TEMPERATURES COULD BE JUST AS COOL IF NOT
COOLER THAN SUNDAY MORNING BEFORE THINGS BEGIN TO WARM UP AS WE MOVE
FORWARD IN THE WORKWEEK. A WEAK AND MOISTURE STARVED LOW PRESSURE
TROUGH WILL MOVE THROUGH ON MONDAY BUT SHOULD HAVE LITTLE SENSIBLE
IMPACT ON OUR REGION BESIDES PERHAPS A FEW SHOWERS IN THE SIERRA. BY
MIDWEEK...STRENGTHENING HIGH PRESSURE PROMISES TO BRING TEMPERATURES
CLOSER TO SEASONAL NORMALS AND ITS LOOKING LIKELY THAT WE WILL BE
SEEING FAIR WEATHER FOR NEW YEAR EVE FESTIVITIES.
