AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
935 AM PST SAT JAN 5 2008

.SYNOPSIS...A POWERFUL PACIFIC STORM CONTINUE TO MOVE TO THE EAST
TODAY BEFORE ANOTHER SYSTEM MOVES INTO THE SOUTHERN SIERRA TONIGHT
AND ACROSS SOUTHERN NEVADA ON SUNDAY RESULTING IN MORE SNOW AND RAIN
FOR THE AREA.
&&

.UPDATE...THE POWERFUL PACIFIC STORM CONTINUES TO MOVE EAST AND
SOUTH THIS MORNING. RAIN AND SNOW QUICKLY TAPERING OFF WITH THE MAIN
ACTIVITY BEING CONFINED TO THE SOUTHERN NEVADA MOUNTAINS AND
NORTHWEST ARIZONA. ALTHOUGH LIGHT SNOW WILL BE SEEN DURING THE DAY
OVER THE SOUTHERN/EASTERN NEVADA MOUNTAINS...HEAVY ACCUMULATIONS ARE
NO LONGER EXPECTED AND HAVE ENDED THE WINTER STORM WARNING/SNOW
ADVISORIES. INTERESTING BAND OF CLOUDS/CONVECTION FORMING CENTRAL
NYE COUNTY TO EXTREME NORTHERN LINCOLN COUNTY AND BEING DEPICTED
WELL BY 12Z GFS...THUS WILL KEEP A LITTLE HIGHER MENTION OF SHOWERS
OVER LINCOLN DURING THE DAY AS THIS AREA PROGGED TO SHIFT NORTHEAST.
WILL BE SHORTLY UPDATING GRIDS/ZONES TO LESSEN SHOWER MENTION MOST
AREAS FOR TODAY. NEXT SYSTEM DUE INTO THE SOUTHERN SIERRA TONIGHT
AND ACROSS THE CWA ON SUNDAY.
&&

.AVIATION...FOR MCCARRAN...WINDS WILL AGAIN BE GUSTY FROM THE
SOUTHWEST TO AROUND 30KTS THROUGH 22Z THEN DECREASE OVERNIGHT. LIGHT
SHOWER ACTIVITY MAY CROSS OVER KLAS...BUT MAIN ACTIVITY TO REMAIN
OVER THE MOUNTAINS....THUS CEILINGS GENERALLY WILL BE BETWEEN 10-12K
FEET. ANOTHER STORM WILL CROSS THE AREA ON SUNDAY FOR A BETTER
CHANCE OF RAIN AND LOWER CIGS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...PACIFIC STORM SLOWLY MOVING TO THE EAST AND SOUTH WITH
DECREASING CLOUDS...SHOWERS ACROSS MOST OF THE ROUTES. HOWEVER...
MOUNTAIN AREAS ABOVE 6000 MSL WILL LIKELY BE OBSCURED THROUGH
SUNDAY. MODERATE OR GREATER TURBULENCE IS ALSO LIKELY IN THE
LEE...NORTHEAST SIDE...OF AREA MOUNTAINS...ESPECIALLY EAST OF THE
SIERRA CREST.
&&

.PREV DISCUSSION...510 AM PST SHORT TERM...SATELLITE AND RADAR
IMAGERY SHOWED THE MAIN PLUME OF MOISTURE AND PRECIPITATION
EXTENDING FROM SOUTHERN CALIFORNIA UP THROUGH SOUTHERN NEVADA AT
12Z. THE MAJORITY OF THE MOISTURE HAD SHIFTED SOUTH OF THE SOUTHERN
SIERRA. THE MAIN FORECAST PROBLEMS INCLUDE HEAVY SNOW CONTINUING IN
THE SOUTHERN NEVADA MOUNTAINS AND LINCOLN COUNTY THIS MORNING AND
ANOTHER ROUND OF HEAVY SNOW IN THE SOUTHERN SIERRA TONIGHT THROUGH
SUNDAY MORNING. CONSIDERING THE LATEST RADAR RETURNS THROUGH
12Z...IT APPEARED THAT THE SOUTHERN NEVADA MOUNTAINS SHOULD SEE AN
ADDITIONAL 6 TO 12 INCHES THIS MORNING BEFORE PRECIPITATION TAPERS
OFF. SNOW LEVELS IN LINCOLN COUNTY WERE NEAR 6000 FEET AND A SPOTTER
IN LINCOLN COUNTY INDICATED THAT A COUPLE INCHES HAD FALLEN IN THE
HILLS ABOVE PIOCHE BY 430 AM. CONTINUED THE WINTER STORM WARNING FOR
THESE AREAS UNTIL NOON. THE SOUTHERN SIERRA SHOULD SEE A BREAK IN
HEAVY SNOWFALL MUCH OF TODAY BUT THE 00Z GFS AND ECMWF CONTINUED TO
INDICATE A SECOND STRONG SHORTWAVE MOVING THROUGH THE BASE OF THE
PACIFIC NORTHWEST LOW WHICH WILL IMPACT THE SOUTHERN SIERRA TONIGHT
THROUGH EARLY SUNDAY. THE BLIZZARD WARNING WAS CANCELLED AND
REPLACED WITH A WINTER STORM WARNING UNTIL NOON SUNDAY. ANOTHER
ISSUE WAS THE GUSTY WINDS WHICH OCCURRED OVERNIGHT BUT THE LATEST
OBSERVATIONS AND MODEL TRENDS INDICATED SPEEDS HAD PEAKED AND SUB
ADVISORY LEVEL WINDS ARE EXPECTED ACROSS MOST OF THE REGION TODAY.
THE WIND ADVISORIES WERE ALLOWED TO EXPIRE FOR INYO COUNTY AND SOUTH
CENTRAL NEVADA. THE LATEST FORECAST IS BASED ON THE GFS AND ECMWF
SOLUTIONS WHICH ARE MORE CLEAR WITH ADDITIONAL MOISTURE AND FORCING
COMING IN WITH THE SECOND WAVE TONIGHT AND SUNDAY. THE WIDE
PRECIPITATION BAND ACROSS SOUTHERN NEVADA THIS MORNING IS FORECAST
TO SHIFT INTO NORTHWEST ARIZONA AROUND 17-20Z. THE SECOND SHOT
TONIGHT AND SUNDAY IS NOT AS WELL DEFINED AS THIS ONE WAS
DEPICTED...BUT SHOULD STILL BRING A BROAD SWATH OF MOISTURE AND
UPWARD FORCING FOR A GOOD CHANCE OF PRECIPITATION TO MUCH OF THE
REGION BY SUNDAY AFTERNOON ALONG WITH LOWERING SNOW LEVELS. THE AXIS
OF THE BROAD PACIFIC TROUGH IS THEN FORECAST TO SHIFT ACROSS THE
ROCKIES MONDAY LEAVING OUR AREA UNDER A DRYING NORTHWEST FLOW
FOLLOWED BY A BRIEF UPPER LEVEL RIDGE MONDAY NIGHT.

.LONG TERM...RIDGING OVER THE AREA ON TUESDAY GETS SHOVED EAST BY
THE NEXT SHORTWAVE TROUGH TO MOVE THROUGH THE AREA AND IS QUICKLY
PAST BY WEDNESDAY AFTERNOON. THIS SYSTEM IS NOT AS MOIST OR POTENT
AS THE WEEKEND SYSTEM. ONLY UNCERTAINTY NOW IS THE DIFFERENCE IN
MOVEMENT SPEED BETWEEN THE MODELS. KEPT THE PRECIPITATION PRIMARILY
CONFINED TO THE NORTH PART OF THE CWA AND INCREASED THEM IN THE INYO
AND ESMERALDA COUNTY MOUNTAINS. THE FLOW WILL RETURN TO
NORTHWESTERLY FOR THE REMAINDER OF THE WEEK WITH NO SIGNIFICANT
WAVES FORECASTED IN THE LATEST MODEL RUNS. A SLIGHT WARM UP IS
EXPECTED BY WEEKS END.
