High Wind in California, February 9, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
308 PM PST SUN FEB 9 2014

.SYNOPSIS...A FAST MOVING DISTURBANCE WILL BRING A CHANCE OF SHOWERS
TO AREAS MAINLY NORTH AND EAST OF LAS VEGAS TONIGHT AND MONDAY
MORNING. WELL ABOVE NORMAL TEMPERATURES WILL OCCUR MONDAY FOLLOWED
BY SLIGHT COOLING TUESDAY. LOCALLY GUSTY NORTH WINDS WILL DEVELOP
MONDAY AND CONTINUE ON TUESDAY...ESPECIALLY DOWN THE COLORADO RIVER
VALLEY. TEMPERATURES WILL WARM THROUGH THE REMAINDER OF THE WEEK
WITH DRY CONDITIONS EXPECTED.
&&

.SHORT TERM...THROUGH TUESDAY NIGHT...A SHORTWAVE TROUGH WAS HELPING
TO ENHANCE THE NEXT ROUND OF HEAVY PRECIPITATION OVER NORTHERN
CALIFORNIA THIS AFTERNOON. MODELS HAVE BEEN CONSISTENT TAKING THIS
FAST MOVING SHORTWAVE SOUTHEAST ACROSS THE SOUTHERN GREAT BASIN AND
MOJAVE DESERT TONIGHT THROUGH MONDAY MORNING. THE SIERRA NEVADA WILL
INTERCEPT MOST OF THE MOISTURE WITH LIGHT SHOWERS EXPECTED ACROSS
OUR FAR NORTHERN AREAS THROUGH MIDNIGHT. AS SHORTWAVE MOVES OVERHEAD
MONDAY MORNING MODELS HAVE GONE BACK AND FORTH ON HOW FAR SOUTH
PRECIPITATION COULD DEVELOP. 12Z ECMWF AND 12Z/18Z GFS BOTH
GENERATE AN EAST-WEST BAND OF LIGHT QPF FROM MESQUITE TO BEATTY...
PLACING THE LAS VEGAS VALLEY ON THE SOUTHERN EDGE. MAINTAINED OUR
HIGHER POPS NORTH AND EAST OF LAS VEGAS...BUT WOULD NOT BE SURPRISED
TO SEE SPRINKLES OR A LGT SHOWER IN NORTHERN PARTS OF THE VALLEY
TOMORROW MORNING. THOSE MORNING SHOWERS WILL SHIFT EAST INTO
NORTHERN MOHAVE COUNTY MONDAY AFTERNOON. THE ENTIRE AREA WILL BE DRY
MONDAY NIGHT THROUGH TUESDAY NIGHT.

IT WILL BE WINDY ACROSS PARTS OF NORTHWEST SAN BERNARDINO COUNTY
TONIGHT WITH GUSTS UP TO 40 MPH POSSIBLE. LOCALLY STRONGER WIND
GUSTS COULD OCCUR ALONG THE EASTERN SIERRA SLOPES AND OWENS VALLEY
SO DECIDED TO ISSUE A WIND ADVISORY THROUGH 6 AM PST MONDAY. WINDS
WILL SHIFT TO A NORTHERLY DIRECTION BEHIND THAT EXITING SHORTWAVE
TROUGH MONDAY. LOCALLY GUSTY NORTH WINDS WILL LINGER DOWN THE
COLORADO RIVER VALLEY THROUGH TUESDAY.

DEEPER MIXING MONDAY SHOULD ALLOW TEMPERATURES TO WARM WELL ABOVE
NORMAL. MINOR COOL DOWN EXPECTED TUESDAY BEFORE TEMPERATURES WARM
THROUGH THE END OF THE WEEK.

.LONG TERM...WEDNESDAY THROUGH SUNDAY NIGHT.

A WARMING TREND WILL BE UNDERWAY BY WEDNESDAY AS A BROAD PERSISTENT
RIDGE CENTERED ALONG 120W NOSES UP INTO THE WESTERN STATES AND HOLDS
THROUGH AT LEAST SATURDAY. MEANWHILE...THE EVEN MORE PERSISTENT
PACIFIC MOISTURE PLUME WILL CONTINUE TO STREAM INTO FAR NORTHERN
CALIFORNIA AND THE PACIFIC NORTHWEST. THE SOUTHERN EDGE OF THIS
MOISTURE WILL PROVIDE VARYING AMOUNTS OF MID AND HIGH CLOUDS FOR OUR
FORECAST AREA DURING THE PERIOD AND MAY INFLUENCE TEMPERATURES A FEW
DEGREES AT TIMES. IN ANY CASE...THIS SCENARIO WILL PUSH HIGH TEMPS
CLOSE TO RECORD LEVELS WITH READINGS EXPECTED IN THE UPPER 70S TO
MID 80S IN THE MOJAVE DESERT REGION FRIDAY INTO SATURDAY. BASED ON
THE LATEST GUIDANCE...VIRTUALLY NO CHANGE WAS MADE TO THE INHERITED
TEMPS.

THE MEDIUM RANGE MODELS ALL SHOW A TROUGH BRUSHING NORTHERN
CALIFORNIA/NEVADA BETWEEN SATURDAY AND SUNDAY. THE MAIN AFFECT IT
WOULD HAVE IS TO INCREASE SOUTHWEST WINDS OVER MUCH OF THE REGION
AND POSSIBLY STRONG WINDS IN THE SOUTHERN SIERRA. THE MAIN STORY FOR
OUR AREA WILL BE UNSEASONABLY WARM TEMPS MOST OF THE PERIOD.
&&

.AVIATION...FOR MCCARRAN...A VARIABLE WIND LESS THAN 6 KTS WILL
TRANSITION SOUTHERLY AFTER 04Z THIS EVENING. NORTHWEST TO NORTH
WINDS WILL INCREASE LATE MONDAY MORNING. SUSTAINED SPEEDS WILL BE
