&&

.UPDATE...BASED ON 12Z GUIDANCE PRIMARY SHIELD OF PRECIPITATION NOW
IMPACTING THE SOUTHERN SIERRA...INYO COUNTY AND ESMERALDA COUNTY
PROGGED TO CONTINUE EAST-NORTHEASTWARD INTO LINCOLN COUNTY LATE THIS

TURNING MUCH COLDER BEHIND THE COLD FRONT WITH GUSTY NORTHWEST WINDS
DEVELOPING THIS EVENING IN CENTRAL NEVADA THEN PUSHING SOUTHEAST
THROUGH THE REST OF THE AREA MONDAY. WILL LOOK IF ANY OTHER ZONES
NEED TO BE INCLUDED IN THE WIND ADVISORY FOR MONDAY DURING THE
AFTERNOON PACKAGE.
&&

.AVIATION...FOR MCCARRAN...CLOUDS WILL CONTINUE TO ROLL IN AND
THICKEN TODAY WITH RAIN DEVELOPING SOMETIME AROUND/AFTER NOON. GUSTY
SOUTHWEST WINDS ARE FORECAST ONCE AGAIN...HOWEVER...TEND TO THINK
THAT AS PRECIS GETS GOING /ESPECIALLY THIS EVENING/ WINDS MIGHT BE
DAMPENED A BIT. CEILINGS WILL MOST CERTAINLY FALL BELOW 5 FT THIS
AFTERNOON AND EVENING. ADDITIONAL HAZARDS INCLUDE BOTH ICING AND
TURBULENCE TODAY...ESPECIALLY BELOW 15 FT. AROUND DAYBREAK
TOMORROW...NORTH/NORTHWEST WINDS AND COLD AIR BEGIN TO FILTER INTO
THE AREA. WINDS COULD ACTUALLY ARRIVE IN FAIRLY LIGHT FORM WITH
LIGHT RAIN/SNOW SHOWERS AROUND BEFORE THE STRONGER GUSTS ARRIVE
LATER IN THE MORNING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...GUSTY SOUTHERLY AND WESTERLY WINDS DEVELOPING ACROSS
THE DESERTS TODAY AS A PACIFIC SYSTEM MOVES IN. EXPECT INCREASING
MID AND LOW LEVEL CLOUDS AS WELL AS RAIN ACROSS ALL TERMINALS TODAY
INTO THIS EVENING. VERY STRONG WINDS ARE EXPECTED AT KDAG WITH GUSTS
IN EXCESS OF 50 KTS THIS EVENING. TURBULENCE IS POSSIBLE AT ALL
LEVELS IN ADDITION TO ICING...ESPECIALLY BELOW 15 FT. NORTH WINDS
BEGIN TO GUST UP ACROSS THE SOUTHERN GREAT BASIN AND NORTHERN
DESERTS BY DAYBREAK TOMORROW.
&&

.SHORT TERM...TODAY AND MONDAY.

SATELLITE SHOWS AN IMPRESSIVE PLUME OF MOISTURE SPREADING INTO
CENTRAL CALIFORNIA THIS MORNING AS THE WELL ADVERTISED PACIFIC STORM
EASES DOWN THE WEST COAST. THE SYSTEM CONTINUES TO DEVELOP AS IT
SINKS SOUTHWARD WITH THE LOW PRESSURE CENTER FORECAST TO BE NEAR THE
NORTHWEST COAST AT 4 AM THIS MORNING. THE SYSTEM DEEPENS AS IT DROPS
INTO CALIFORNIA AND NEVADA OVER THE NEXT 24 HOURS. A HOST OF WINTER
WEATHER AND WIND PRODUCTS ARE EITHER IN EFFECT OR SET TO GO INTO
EFFECT TODAY/TONIGHT AND CONTINUE THROUGH MUCH OF MONDAY. FOR
DETAILS, INCLUDING AREAS AFFECTED, SEE PRODUCTS ON OUR WEBSITE AT
WEATHER.GOV/LASVEGAS.

A WINTER STORM WARNING CONTINUES AT THIS TIME FOR THE SOUTHERN
SIERRA WITH WINTER WEATHER ADVISORIES AND WINTER STORM WARNINGS
GOING INTO EFFECT THIS AFTERNOON FOR THE SOUTHERN GREAT BASIN, THE
SHEEP RANGE AND SPRING MOUNTAINS AND PORTIONS OF MOHAVE COUNTY.
THERE COULD BE A PERIOD OF SNOWFALL ENHANCEMENT LATER TODAY AS THE
LOW STRENGTHENS AND WRAPS MOISTURE INTO THE MOUNTAIN AREAS. COLD AIR
MOVES IN BEHIND THE LOW AND WILL LOWER SNOW LEVELS TO 3000 FEET OR
POSSIBLY LOWER. HOWEVER, THE DEEPER MOISTURE MAY BE ON THE WAY OUT
AS THE COLDEST AIR ARRIVES. THE SYSTEM REMAINS CLOSE ENOUGH EARLY
MONDAY MORNING WITH MOISTURE WRAPPING AROUND THE BACKSIDE OF THE LOW
INTO LINCOLN, CLARK AND MOHAVE COUNTIES THAT WE COULD SEE SNOW
SHOWERS IN THE LAS VEGAS VALLEY. 700MB TEMPERATURES OFF THE GFS
SUGGESTS SNOW LEVELS BETWEEN 2000 AND 3000 FEET MONDAY MORNING.
PRECIPITATION ENDS MONDAY AS THE LOW MOVES OFF TO THE EAST.

WIND IS ANOTHER CONCERN WITH THIS SYSTEM. MODEL DATA AND MOS
GUIDANCE SHOWS STRONG WINDS DEVELOPING IN SOUTHERN MOHAVE COUNTY
THIS AFTERNOON AND A WIND ADVISORY HAS BEEN ISSUED FOR THIS AREA.
LATE THIS AFTERNOON THROUGH MONDAY, A HIGH WIND WARNING IS IN EFFECT
FOR THE WESTERN MOHAVE DESERT AND THE TWENTYNINE PALMS AREA. WIND
GUSTS OVER 60 MPH ARE POSSIBLE IN THESE AREAS. STRONG NORTHWEST
WINDS SOUTHWARD ACROSS THE AREA TONIGHT AND MONDAY BEHIND THE
SYSTEM. THE STRONGEST WINDS ARE FORECAST TO IMPACT ESMERALDA AND
CENTRAL NYE COUNTIES WHERE A HIGH WIND WARNING WILL GO INTO EFFECT
TONIGHT. OTHER AREAS COULD SEE ADVISORY LEVEL WINDS AS THE NORTH
WINDS PUSH SOUTH THROUGH THE SOUTHERN GREAT BASIN INTO THE MOJAVE
DESERT LATE TONIGHT THROUGH MONDAY. THE LAS VEGAS VALLEY WAS NOT
INCLUDED IN THE ADVISORY SINCE THE WIND FORECAST KEEPS WINDS BELOW
ADVISORY CRITERIA. HOWEVER, THERE COULD BE A BRIEF PERIOD OF STRONG
ENHANCED WINDS AS THE FRONT BLOWS THROUGH EARLY MONDAY MORNING.

A COOLING TREND BEGINS TODAY WITH FORECAST HIGH TEMPERATURES MORE
THAN 15 DEGREES COOLER THAN YESTERDAY. BY MONDAY, TEMPERATURES COULD
DROP ANOTHER 10 DEGREES WITH HIGHS STRUGGLING TO REACH 50 DEGREES IN
LAS VEGAS. COMBINED WITH THE GUSTY NORTH WINDS, IT WILL CERTAINLY
FEEL CHILLY.

LONG TERM...TUESDAY THROUGH SATURDAY

COMPUTER MODEL GUIDANCE IN FAIRLY GOOD AGREEMENT IN THE EARLY
PORTION OF THE EXTENDED FORECAST. THERE IS HIGH CONFIDENCE IN A
UPPER LEVEL RIDGE SETTING UP JUST OFF THE WEST COAST LEADING TO
WARMER AND DRY CONDITIONS COMPARED TO WHAT WE ARE DEALING WITH THIS
WEEKEND. LATER IN THE WEEK DISCREPANCIES IN THE PATTERN EMERGE. THE
GFS TENDS TO BRING A FAIR AMOUNT OF SHORT WAVE ENERGY UNDER THE
RIDGE AND EVENTUALLY FORMING A REC BLOCK. THIS WOULD MEAN PERIODS OF
SLIGHTLY COOLER TEMPS AND MORE CLOUDS BUT LITTLE IN THE WAY OF
PRECIPITATION. THE ECMWF KEEPS THIS SHORT WAVE ENERGY IN THE
NORTHERN STREAM OVER THE TOP OF THE RIDGE...BUT EVENTUALLY DRIVES A
STRONG SHORT WAVE INTO THE INTERMOUNTAIN WEST BY THE WEEKEND. THIS
WOULD MEAN A STRONG NORTH WIND SCENARIO FOR THE AREA. WE WILL SEE
WHAT OCCURS WITH THE NEXT FEW MODEL RUNS BEFORE MAKING APPRECIABLE
CHANGES TO THE FORECAST.
&&

.SPOTTER INFORMATION STATEMENT...HIGH WINDS AND SIGNIFICANT SNOW
AMOUNTS ARE POSSIBLE THROUGH MONDAY. SPOTTER ACTIVATION IS NOT
ANTICIPATED HOWEVER PLEASE REPORT SIGNIFICANT WEATHER ACCORDING TO
STANDARD OPERATING PROCEDURES.
