AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
908 PM PST SAT JAN 24 2009

.SYNOPSIS...A DEVELOPING STORM SYSTEM WILL BRING LOCALLY HEAVY SNOW
TO THE SOUTHERN GREAT BASIN SUNDAY AND MONDAY...WHILE THE MOJAVE
DESERT SEES BREEZY CONDITIONS AND A SLIGHT CHANCE OF RAIN. THE
CHANCES FOR RAIN AND SNOW WILL END AS THE STORM MOVES AWAY TO THE
EAST TUESDAY...AND GENERALLY DRY WEATHER IS EXPECTED WEDNESDAY
THROUGH SATURDAY. TEMPERATURES WILL RISE ABOVE NORMAL BY THE END OF
THE WEEK.
&&

.UPDATE...RECENT OBSERVATIONS AND THE 00Z RUNS OF THE NAM AND GFS
SUPPORT THE GOING OVERALL FORECAST TRENDS. THE LOW PRESSURE SYSTEM
CURRENTLY OVER NORTHERN CALIFORNIA WILL MOVE SOUTHEAST AND SETTLE
OVER THE SOUTHERN GREAT BASIN BY SUNDAY EVENING AHEAD OF THE BROAD
COLD TROUGH DROPPING DOWN THROUGH WESTERN CANADA. NO UPDATE PLANNED
FOR THE FIRST TWO FORECAST PERIODS THIS EVENING.

THE SYSTEM IS STILL FORECAST TO REMAIN INLAND AND BE FAIRLY
PROGRESSIVE. THE GFS CONTINUES TO SHOW THE CORE OF THE STORM QUICKLY
PULLING EAST INTO THE SOUTHERN ROCKIES TUESDAY MORNING LEAVING DRY
NORTHERLY FLOW OVER SOUTHERN NEVADA AND SURROUNDING AREAS.
&&

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS SHOULD REMAIN AROUND
8-10 KTS MUCH OF THE NIGHT AND EARLY SUNDAY MORNING IN RESPONSE TO
AN INCOMING LOW PRESSURE SYSTEM OVER NORTHERN CALIFORNIA. SOUTHWEST
WINDS WILL LIKELY INCREASE AFTER 18Z AND SPEEDS OF 18G26KT APPEAR
TO BE A GOOD BET FOR LATE SUNDAY MORNING THROUGH THE AFTERNOON. LATE
IN THE TAF (00Z) PERIOD MID LEVEL CLOUDS WILL INCREASE ACROSS THE
AREA IN ADVANCE OF THE NEXT STORM SYSTEM BUT NO CEILINGS ARE
EXPECTED OR IF THEY DO ARE NOT EXPECTED TO HAVE AN IMPACT ON KLAS
CONFIGURATION. LATE SUNDAY NIGHT AND INTO MONDAY WILL SEE LOWER CIGS
AND A CHANCE FOR RAIN IN THE VALLEY AND SNOW IN AND NEAR BY
MOUNTAINS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...GUSTY SOUTHWEST WINDS WILL OCCUR LATE SUNDAY MORNING
THROUGH SUNDAY EVENING. THE NEXT STORM SYSTEM APPROACHES THE AREA
LATE SUNDAY NIGHT. EXPECT LOW CIGS AND VSBY WITH SNOW LATE SUNDAY
NIGHT IN NORTHERN LINCOLN COUNTY AND IN CENTRAL NYE COUNTY.
&&

.PREV DISCUSSION.../311 PM PST SAT JAN 24 2009/

.SHORT TERM...SATELLITE SHOWS SCATTERED TO LOCALLY BROKEN CLOUDS
OVER MUCH OF OUR CWFA. AREA RADARS WERE SHOWING FEW ECHOES...BUT
SEVERAL STATIONS WERE REPORTING LIGHT PRECIP...ESPECIALLY IN LINCOLN
AND MOHAVE COUNTIES. SATELLITE SUGGESTS THAT THE CLOUDS ARE QUITE
SHALLOW...SO THE RADAR BEAMS WERE OVERSHOOTING MOST OF THEM...THUS
THE PRECIP WITHOUT RADAR ECHOES. SURFACE OBS ALSO SHOWED THAT
DEWPOINTS HAD DROPPED AS MUCH AS 10 DEGREES SINCE THIS MORNING...SO
DO NOT EXPECT A REPEAT OF THE PATCHY DENSE FOG WE SAW THIS MORNING.
THE NEXT FEATURE OF CONCERN WILL BE THE JET STREAK WHICH IS SEEN ON
WATER VAPOR OVER THE GULF OF ALASKA CRESTING THE EASTERN PACIFIC
RIDGE. AS THIS FEATURE DIVES SOUTH OFF THE WEST COAST SUNDAY...IT
WILL COMBINE WITH THE SHORTWAVE TROUGH SEEN OVER NORTHERN BRITISH
COLUMBIA AND ALBERTA TO CARVE OUT A DEEP TROUGH OVER THE WESTERN
STATES. WITHIN THIS DEEP TROUGH...A NICE BAND OF DEFORMATION AND
FRONTOGENESIS SETS UP NEAR THE NORTHERN BORDER OF OUR CWFA SUNDAY
NIGHT THROUGH MONDAY. THIS WILL LIKELY RESULT IN A BAND OF HEAVY
SNOW...AND AFTER COORDINATION WITH WFO LKN...HAVE ISSUED A WINTER
STORM WATCH FOR ESMERALDA...CENTRAL NYE...AND LINCOLN COUNTIES. SNOW
LEVELS WILL START OUT AROUND 5000-5500 FEET SUNDAY EVENING...AND
WILL FALL TO AROUND 4000 FEET BY MONDAY AFTERNOON. IT APPEARS THAT
THE GREATEST THREAT FOR HEAVY SNOW WILL REMAIN EAST OF HIGHWAY
95...BUT CANNOT BE CERTAIN THE HIGHWAY WILL NOT BE AFFECTED. HIGHWAY
93...ESPECIALLY FROM CALIENTE NORTH...IS LIKELY TO SEE SIGNIFICANT
SNOW. THE MODELS HAVE STRONGLY TRENDED TOWARD THE MAIN TROUGH AXIS
BEING MORE PROGRESSIVE THAN EXPECTED EARLIER...AND HAVE TRENDED POPS
DOWN TUESDAY AS THE TROUGH AXIS IS EXPECTED TO BE WORKING ITS WAY
TOWARD THE SOUTHEAST CORNER OF OUR CWFA BY THAT TIME.

.LONG TERM...GREATER CLARITY COMES TO THE EXTENDED...WEDNESDAY
THROUGH SATURDAY...AS MODELS SETTLE DOWN AND MERGE TOWARDS SOMETHING
APPROACHING A CONSENSUS. IT APPEARERS THE NEXT STORM THAT IS HANDLED
BY THE SHORT TERM FORECAST/FORECASTER WILL BE MORE PROGRESSIVE AND
BE MOSTLY THROUGH THE CWA BY WEDNESDAY LEAVING THE AREA IN DRYING
NORTHWEST FLOW. THERE WILL STILL BE SOME RESIDUAL MOISTURE IN OUR
EASTERN ZONES FOR SOME LINGERING SHOWERS IN MOHAVE COUNTY WEDNESDAY.
AFTER THAT MUCH DRYER CONDITIONS WILL PREVAIL AND SLIGHT WARMING BY
WEEKS END AS RIDGING EDGES IN FROM THE WEST.

.VEF WATCHES/WARNINGS/ADVISORIES...
NV...WINTER STORM WATCH FOR ZONES 14 AND 15 SUNDAY EVENING THROUGH
     MONDAY AFTERNOON.
AZ...NONE.
