SYNOPSIS
 
A STRONG LOW OFF THE PACIFIC NORTHWEST COAST WILL BEGIN  
TO INFLUENCE OUR WEATHER STARTING ON THURSDAY WITH AN INCREASE IN  
WINDS. THE WINDS WILL CONTINUE TO INCREASE INTO SATURDAY WHEN MUCH  
OF THE AREA WILL SEE STRONG AND GUSTY WINDS. SNOW IN THE EASTERN  
SIERRA SLOPES AND WHITE MOUNTAINS FRIDAY MORNING THROUGH EARLY  
SUNDAY MORNING. MORE TRANQUIL WEATHER EXPECTED TO START THE WORK  
WEEK.
 
   
SHORT TERM
 
TONIGHT THROUGH SATURDAY.  
 
AN UPPER LEVEL LOW OFF OF THE PACIFIC NORTHWEST COAST WILL BE SLOWLY  
WORKING ITS WAY TOWARD THE COAST OF THE NEXT FEW DAYS. THE SYSTEM  
WILL BE RESPONSIBLE FOR THE INCREASE IN WIND THAT THE SOUTHERN GREAT  
BASIN AND MOJAVE DESERT WILL EXPERIENCE BEGINNING ON THURSDAY. A  
STRONG (130+ KT) JET WILL ASSOCIATED WITH THE UPPER LOW WILL WORK  
ITS WAY ACROSS OUR AREA ON SATURDAY PROVIDING THE PEAK IN WIND  
SPEEDS THAT DAY. SOUTHWEST WINDS WILL INCREASE ON THURSDAY AFTERNOON  
WITH ONLY A FEW ISOLATED LOCATIONS EXPECTED TO NEAR OR REACH ABOVE  
40 MPH. WINDS IN MOST LOCATIONS WITH INCREASE FURTHER ON FRIDAY AND  
THERE MAY BE A NEED FOR A WIND ADVISORY IN A FEW LOCATIONS. NBM AND  
ENSEMBLE PROBABILITIES CONTINUE TO INCREASE IN THAT REGARD. THE MAIN  
EVENT WILL DEFINITELY BE ON SATURDAY AND A HIGH WIND WATCH HAS BEEN  
ISSUED FOR MUCH OF SOUTHERN NEVADA AND PORTIONS OF SOUTHEAST  
CALIFORNIA AND NORTHERN MOHAVE COUNTY.  
 
THE LATEST EFI VALUES FOR WIND ARE QUITE ANOMALOUS ACROSS THE  
SOUTHERN GREAT BASIN AND MOJAVE DESERT AND FOR THIS WINDIER TIME OF  
YEAR EVEN MORE UNUSUAL. THE LATEST RUN OF THE NBM SHOWS A SWATH OF  
HIGHER PROBABILITIES (40-60%) FROM WESTERN SAN BERNARDINO COUNTY UP  
THROUGH THE SPRING MOUNTAINS, NNSS AND NORTHERN LINCOLN COUNTY FOR  
WIND GUSTS EXCEEDING 70 MPH, WITH A POCKET OF THE HIGHEST  
PROBABILITIES IN THE SPRING MOUNTAINS ON EARLY SATURDAY AFTERNOON  
THAT EXCEED 70%.  
 
ADDITIONALLY, RAIN AND SNOW WILL ACCOMPANY THE WIND ON SATURDAY  
PARTICULARLY IN THE HIGHER ELEVATIONS OF SOUTHERN NEVADA AND  
NORTHERN MOHAVE COUNTY. SNOW LEVELS WILL START OUT AROUND 6000 FEET  
AND GRADUALLY LOWER DURING THE AFTERNOON AND EVENING HOURS. MOISTURE  
WILL BE LIMITED IN THE SPRING MOUNTAINS WHERE ARE FEW INCHES ARE  
EXPECTED BUT THE MAIN ISSUE THERE WILL BE THE WIND AND THE  
COMBINATION OF WIND AND SNOW, GREATLY REDUCING VISIBILITY. THE SECOND  
AREA OF COMBINED WIND AND SNOW IMPACTS WILL BE OVER THE NORTHERN  
HALF OF LINCOLN COUNTY AND A WINTER STORM WATCH HAS BEEN ISSUED  
THERE FOR SATURDAY. ALTHOUGH SNOW AMOUNTS WILL NOT BE UNUSUALLY HIGH  
WITH THIS SYSTEM THE COMBINATION OF WIND AND SNOW WILL MAKE TRAVEL  
EXTREMELY HAZARDOUS, ESPECIALLY ALONG HIGHWAY 93 NORTH OF PIOCHE.  
WHITEOUT CONDITIONS WILL BE POSSIBLE.  
 
ELSEWHERE THE PRIOR WINTER STORM WARNINGS REMAINED LARGELY UNCHANGED  
AND SNOW AMOUNTS WILL BE SIGNIFICANTLY HIGHER IN THE HIGHER TERRAIN  
OF INYO COUNTY, PARTICULARLY IN THE LEE OF THE SIERRA.  
 
THE MAIN TROUGH AXIS WILL PUSH TO THE EAST OF THE AREA SATURDAY  
NIGHT AND VERY QUICKLY THE WINDS AND PRECIP WILL COME TO AN END.  
   
LONG TERM
 
SUNDAY THROUGH WEDNESDAY.  
 
A COOL AND DRY NORTHWEST FLOW WILL BE IN PLACE FOR SUNDAY AND MONDAY  
WITH LOW TEMPS IN THE 30S AND HIGHS IN THE UPPER 50S TO LOWER 60S  
ACROSS THE DESERT ZONES. ADDITIONAL DISTURBANCES UPSTREAM OVER THE  
EASTERN PACIFIC MAY MOVE INTO THE CALIFORNIA COAST TUESDAY AND  
WEDNESDAY, BUT THE LATEST NBM INDICATES NOT MUCH POTENTIAL FOR ANY  
SIGNIFICANT PRECIPITATION.
