AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
829 AM PST WED DEC 18 2013

.SYNOPSIS...OCCASIONAL HIGH CLOUDS AND ABOVE NORMAL TEMPERATURES
WILL BE SEEN THROUGH TODAY AHEAD OF A DEVELOPING STORM SYSTEM. THIS
SYSTEM WILL MOVE INTO SOUTHERN CALIFORNIA BY THURSDAY AFTERNOON AND
INTO NORTHERN MEXICO BY FRIDAY. THIS WILL RESULT IN UNSETTLED
WEATHER THURSDAY AND FRIDAY OVER MUCH OF THE AREA ALONG WITH
TEMPERATURES COOLING TO NEAR NORMAL INTO THE WEEKEND.
&&

.UPDATE...RECENT SATELLITE LOOPS SHOW MOSTLY CLOUDY SKIES ACROSS THE
VAST MAJORITY OF THE FORECAST AREA THIS MORNING. WEAK RADAR RETURNS
LOOK TO BE MAINLY VIRGA SHOWERS BASED ON VERY DRY LOW LEVELS...VISUAL
EVIDENCE...AND THE LACK OF PRECIPITATION IN ANY GAUGES THUS FAR. HAVE
UPDATED SKY/POP/WX GRIDS TO REFLECT THESE LATEST TRENDS. MAINLY
VIRGA SHOWERS OR LIGHT MOUNTAIN SHOWERS ARE EXPECTED THROUGH TODAY
WITH NO REAL ACCUMULATION. MAIN FOCUS CONCERN TODAY WILL BE THE
SYSTEM EXPECTED THURSDAY INTO FRIDAY AND THE WINTER STORM WATCH
CURRENTLY OUT FOR THE MOUNTAINS OF THE NORTHWEST PORTION OF THE
FORECAST AREA.
&&

.PREV DISCUSSION...
ISSUED 307 AM PST WED DEC 18 2013

.SHORT TERM...TODAY THROUGH SATURDAY MORNING...CONSIDERABLE HIGH
CLOUDS WILL REMAIN OVER THE AREA AGAIN TODAY AS A DEEPENING AREA OF
LOW PRESSURE TAKES SHAPE OVER THE PACIFIC NORTHWEST. THE MODELS HAVE
BEEN FAIRLY CONSISTENT IN SHOWING A WEAK RIPPLE WHICH IS CURRENTLY
OFF THE SOUTHERN CALIFORNIA COAST MOVING NORTHEAST DURING THE DAY.
IT LOOKS LIKE THERE WILL BE JUST ENOUGH ENERGY WITH THIS FEATURE TO
BRING SOME LIGHT ISOLATED SHOWERS TO MAINLY THE NORTHERN HALF OF THE
CWA TODAY. ITS NOT OUT OF THE QUESTION THAT THE SPRING MOUNTAINS
COULD ALSO SEE A FEW LIGHT SHOWERS THIS AFTERNOON. SNOW LEVELS WILL
REMAIN QUITE HIGH TODAY SO ANY PRECIPITATION THAT DOES FALL WILL
REMAIN ALL RAIN. BIGGER CHANGES WILL OCCUR TONIGHT AND THURSDAY AS A
FAIRLY DEEP TROUGH WHICH STRETCHES FROM MONTANA TO CALIFORNIA STARTS
TO DIG AND EVENTUALLY FORM A CLOSED LOW OVER CENTRAL CALIFORNIA. A
COMBINATION OF DYNAMICS...UPSLOPE AND STRONG MID LEVEL DIFFLUENCE
WILL ALLOW FOR FAIRLY WIDESPREAD SHOWERS TO DEVELOP OVER PORTIONS OF
CENTRAL NEVADA STRETCHING INTO NORTHERN INYO COUNTY. MUCH COLDER AIR
WILL ALSO BE ADVECTING INTO WEST CENTRAL NEVADA AND INYO COUNTY AND
IS EXPECTED TO BRING SNOW LEVELS DOWN TO AROUND 5000 FEET. THE
MODELS INCLUDING THE HIRES MODELS ARE ALL INDICATING FAIRLY HIGH
POPS EARLY THURSDAY AFTERNOON UNTIL THURSDAY EVENING OVER ESMERALDA
AND NORTHERN INYO COUNTIES. HAVE ELECTED TO ISSUE A WINTER STORM
WATCH FOR THESE AREAS ABOVE 5000 FEET FROM 18Z THURSDAY TO 06Z
FRIDAY. AMOUNTS ARE EXPECTED TO GENERALLY BE BETWEEN 4-7 INCHES
ABOVE 5000 FEET. THE EASTERN SIERRA AND WHITE MOUNTAINS COULD SEE A
LITTLE MORE DUE TO SOME UPSLOPE ENHANCEMENT. BY THURSDAY NIGHT AND
BETTER DIFFLUENCE SHIFTS SOUTHEAST AND SHOULD BRING AT LEAST SOME
ISOLATED TO SCATTERED SHOWERS TO THE REMAINDER OF THE
CWA...ESPECIALLY SAN BERNARDINO AND MOHAVE COUNTIES. ITS ALSO NOT
OUT OF THE QUESTION TO SEE SOME ISOLATED THUNDERSTORMS OVER THESE
AREAS LATE THURSDAY AFTERNOON AS THE MODELS ARE INDICATING LI VALUES
CLOSE TO ZERO. THIS LOW WILL CONTINUE TO TRACK SOUTHEAST THURSDAY
NIGHT AND SOME RESIDUAL MOISTURE MAY REMAIN OVER THE FAR SOUTHERN
AREAS OF THE CWA INTO FRIDAY. TEMPERATURES TODAY ARE EXPECTED TO
REMAIN A FEW DEGREES ABOVE NORMAL...BUT COOL AROUND 6-8 DEGREES
THURSDAY AND FRIDAY AS THE FLOW TURNS NORTH BEHIND THE TROUGH. SOME
WEAK ENERGY MAY DIG INTO NORTHERN NEVADA LATE FRIDAY NIGHT AND DID
GO AHEAD AND ADD A SLIGHT CHANCE OF PRECIPITATION FOR MAINLY LINCOLN
COUNTY.

.LONG TERM...SATURDAY THROUGH TUESDAY...ENHANCED NORTHERLY FLOW WILL
PREVAIL OVER THE FORECAST AREA SATURDAY AND SUNDAY ON THE BACK SIDE
OF THE UPPER LOW WHICH WILL LIFT UP THROUGH TEXAS SATURDAY.
SHORTWAVE ENERGY IS FORECAST TO QUICKLY MOVE DOWN OVER THE GREAT
BASIN SATURDAY WHICH WILL REINFORCE NORTH BREEZES INTO
SUNDAY...ESPECIALLY DOWN THE COLORADO RIVER VALLEY. RIDGING ALONG
THE WEST COAST WILL PROVIDE A WEAK NORTHWEST FLOW MONDAY INTO
TUESDAY BUT MEDIUM RANGE MODELS ARE BEGINNING TO DIVERGE
CONSIDERABLY GOING INTO THE MIDDLE OF NEXT WEEK. THE MAIN DEVIANT IS
THE ECMWF WHICH NOW INDICATES A TROUGH DIGGING DOWN THROUGH THE
GREAT BASIN AND INTO SOUTHERN NEVADA AND NORTHERN ARIZONA BY
CHRISTMAS DAY. THE GFS AND GEM SHOW NO HINT OF THIS AND TAKE THE
SAME TROUGH ACROSS THE NORTHERN PLAINS AND UPPER MIDWEST INSTEAD.
WILL KEEP AN EYE ON THIS PATTERN TO SEE HOW IT EVOLVES BUT NO
SIGNIFICANT CHANGES WERE MADE FOR NOW. TEMPERATURES DURING THE
PERIOD WILL VARY LITTLE AND HIGHS WILL BE WITHIN A FEW DEGREES OF
NORMAL.
&&

.AVIATION...FOR MCCARRAN...CONSIDERABLE HIGH CLOUDS WITH WINDS
GENERALLY LESS THAN 8 KTS EXPECTED THROUGH TODAY. A PACIFIC STORM
WILL MOVE DOWN THE CALIFORNIA COAST BEGINNING WEDNESDAY NIGHT
BRINGING INCREASED/LOWERED CLOUD BASES TO THE VALLEY AND A CHANCE OF
SHOWERS OVER MAINLY THE SURROUNDING MOUNTAINS BY THURSDAY. IMPROVING
CONDITIONS ARE EXPECTED FRIDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...CONSIDERABLE HIGH CLOUDS THROUGH TODAY WITH WINDS
GENERALLY LESS THAN 10 KTS AREAWIDE. A PACIFIC STORM WILL MOVE DOWN
THE CALIFORNIA COAST LATE TONIGHT RESULTING IN INCREASING AND
LOWERING CLOUD BASES AROUND THE REGION. MOST OF THE AREA WILL SEE
PRECIPITATION CHANCES INCREASE THURSDAY WITH THE MORE WIDESPREAD
PRECIPITATION OCCURRING OVER INYO AND ESMERALDA COUNTIES. CIGS COULD
LOWER TO AROUND 3-5K FEET OVER THOSE AREAS WITH MAINLY 8-10K FEET
ELSEWHERE.
