AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
918 AM PST SUN JAN 27 2013

.SYNOPSIS...ANOTHER PACIFIC STORM WILL MOVE INTO THE AREA TODAY
BEFORE EXITING THE REGION ON MONDAY. THIS SYSTEM WILL BRING A CHANCE
OF SHOWERS TO MAINLY THE SOUTHERN SIERRA AS WELL AS THE SOUTHERN
NEVADA AND NORTHWEST ARIZONA MOUNTAINS. COLDER AIR WILL DROP
TEMPERATURES TO BELOW NORMAL ON MONDAY...BUT DRYING AND WARMER
CONDITIONS EXPECTED TUESDAY THROUGH THE REMAINDER OF THE WEEK.
&&

.UPDATE...LOW CLOUDS ARE PERSISTING ACROSS SOUTHWEST MOHAVE AND
EASTERN SAN BERNARDINO COUNTY MORE THAN PREVIOUSLY FORECAST AND THE
LATEST MODEL SOLUTIONS INDICATE THAT MOISTURE WILL LINGER MUCH OF
THE DAY. UPDATED TO INCREASE SKY COVER TODAY IN THAT AREA. LATEST
MODEL RUNS ALSO AGREE THAT THE AREA FROM SOUTHEAST LINCOLN TO
NORTHERN MOHAVE COUNTY COULD RECEIVE A DECENT AMOUNT OF
PRECIPITATION BETWEEN 18Z AND 00Z SO I INCREASED POPS IN THAT AREA
TODAY. WINDS HAVE REALLY INCREASED IN AND ALONG THE SPRING MOUNTAINS
THIS MORNING. RED ROCK REPORTED A GUST TO 54 MPH ON THEIR LATEST
OBSERVATION AND 53 MPH WAS REPORTED ON DEER CREEK HIGHWAY. HIGH
RESOLUTION MODELS INDICATE STRONG WINDS CONTINUING THERE THROUGH THE
AFTERNOON. I ISSUED A WIND ADVISORY FOR THAT ZONE VALID UNTIL 6 PM.
&&

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS OF 20-30KTS ARE EXPECTED
THROUGH TODAY AHEAD OF A COLD FRONT THAT IS FORECAST TO PUSH THROUGH
THE VALLEY AROUND 04-06Z TONIGHT...ALTHOUGH ITS POSSIBLE THAT THE
FRONT MAY STALL OVER THE NORTHERN HALF OF THE VALLEY AND KEEP
SOUTHWEST TO WEST WINDS THROUGH 10-12Z BEFORE TURNING NORTHWEST.
ONCE THE FRONT PASSES NORTHWEST WINDS BETWEEN 10-15KTS ARE EXPECTED.
FEW-SCT CLOUDS AT 5K FEET THROUGH TODAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...AREAS OF PATCHY FOG WILL CONTINUE TO DISSIPATE EARLY
THIS MORNING AS SOUTHWEST WINDS INCREASE ACROSS THE AREA. THESE
SOUTHWEST WINDS WILL CONTINUE TO INCREASE THROUGH THE MORNING WITH
GUSTS TO 25-30 KNOTS POSSIBLE THIS AFTERNOON. A COLD FRONT WILL
BRING A SHIFT TO GUSTY NORTHWEST WINDS AS IT MOVES SOUTHEAST ACROSS
THE FORECAST AREA THIS AFTERNOON AND EVENING. SHOWERS ARE EXPECTED
AHEAD OF AND ALONG THIS FRONT...MAINLY ACROSS ESMERALDA...NYE...
LINCOLN...AND MOHAVE COUNTIES TODAY AND TONIGHT. SCT-BKN CLOUDS AT
5-8K FEET ARE EXPECTED THROUGH THE PERIOD.

.PREV DISCUSSION...
310 AM PST SUN JAN 27 2013

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...A FEW SHOWERS ARE BEING
SEEN OVER MOHAVE COUNTY THIS MORNING AS THE REMNANTS OF THE SYSTEM
WHICH MOVED INTO THE REGION ON SATURDAY CONTINUE TO SHIFT EAST.
GENERALLY DRY CONDITIONS SEEN ELSEWHERE ACROSS THE CWA. HOWEVER
PATCHY FOG DEVELOPED SATURDAY NIGHT WHICH WILL CONTINUE INTO THIS
MORNING BEFORE DISSIPATING. AS SATURDAYS STORMS SHIFTS EAST...THE
NEXT PACIFIC STORM IS PUSHING INTO WESTERN NEVADA AND WILL BE MOVING
INTO THE FORECAST AREA BY EARLY MORNING. THIS SYSTEM WILL BE COLDER
THAN SATURDAYS STORM AND AS IT TRANSITIONS SOUTHEAST ACROSS THE AREA
TODAY AND TONIGHT LOWERING SNOW LEVELS WILL BE SEEN ALONG WITH
COLDER TEMPERATURES GOING INTO MONDAY. THE EVENING MODEL RUNS ARE
ALL IN GOOD AGREEMENT THAT THE MAIN FRONTAL FORCING/BEST
PRECIPITATION WILL BE TO THE NORTH OF THE FORECAST AREA. HOWEVER
INCREASE DYNAMICS WILL BRING AN INCREASING CHANCE OF SHOWERS TODAY
TO THE NORTHERN MOUNTAINS AND THEN ACROSS THE EASTERN PORTION OF THE
AREA LATE TODAY INTO MONDAY. WITH THE LOWERING SNOW
LEVELS...FORECASTED TO BE NEAR 4000 FEET BY 12Z MONDAY...SNOW
ACCUMULATIONS ARE EXPECTED IN THE AREA MOUNTAINS. THE MAIN CONCERN
WILL BE LINCOLN COUNTY WHERE 1-3 INCHES MAY BE POSSIBLE WHICH IS
BELOW SNOW ADVISORY CRITERIA. WILL CLOSELY MONITOR THOUGH AS IF THE
FRONTAL FORCING DROPS A LITTLE FURTHER SOUTH...A SNOW ADVISORY MAY
BE NEEDED FOR THIS AREA. BY MONDAY THE TROUGH WILL CONTINUE TO SHIFT
EAST WITH DRYING EXPECTED FROM THE WEST. SHOWERS SHOULD CLEAR THE
CWA BY 12Z TUESDAY WITH DRY NORTH TO NORTHWEST FLOW ALOFT.

INCREASED WINDS WILL BE SEEN AS THIS SYSTEM MOVES ACROSS THE AREA
WITH LOCAL GUSTY SOUTHWEST WINDS TODAY. AT THE SAME TIME BRIEF
DOWNSLOPE CONDITIONS MAY BE SEEN ON THE EAST SIDE OF THE AREA
MOUNTAINS TODAY WITH WINDS POSSIBLY REACHING ADVISORY LEVELS...GUSTS
TO 40 MPH OR GREATER...ESPECIALLY IN THE OWENS VALLEY OF INYO COUNTY
AS WELL AS THE RED ROCK LOOP IN CLARK COUNTY. ONCE AGAIN WILL
MONITOR AS THE DURATION OF THE WINDS SHOULD BE BRIEF. THE
SOUTHWEST WINDS WILL BE SWITCHING TO THE NORTH AS THE FRONT PUSHES
ACROSS THE AREA WITH THE EXPECTED FRONTAL PASSAGE ACROSS LAS VEGAS
BETWEEN 03Z AND 06Z MONDAY. LOCAL GUSTY NORTH WINDS WILL THEN BE
SEEN ON MONDAY...BUT THE NORTHERLY FLOW ALOFT AND DEVELOPING SURFACE
GRADIENTS ON TUESDAY WILL PRODUCE THE BEST NORTH WINDS...ESPECIALLY
ALONG THE COLORADO RIVER VALLEY.

TEMPERATURES WILL CONTINUE TO BE NEAR NORMAL FOR TODAY...ESPECIALLY
ACROSS THE SOUTHERN PORTION OF THE REGION...HOWEVER WITH THE FRONTAL
PASSAGE TONIGHT...TEMPERATURES WILL DROP 5 TO 10 DEGREES ON MONDAY
RESULTING IN BELOW NORMAL TEMPERATURES FOR MONDAY AND TUESDAY.

.LONG TERM...WEDNESDAY THROUGH SATURDAY...MODELS ARE IN FAIRLY GOOD
AGREEMENT THROUGH THE LONG TERM PERIOD AND NO SIGNIFICANT CHANGES
WERE MAKE TO THE INHERITED FORECAST.

A RIDGE OF HIGH PRESSURE WILL BE MOVING INTO THE WESTERN CONUS IN
THE WAKE OF THIS WEEKENDS TROUGH. DRY NORTHERLY FLOW WILL KEEP
BREEZY CONDITIONS POSSIBLE AT TIMES DOWN THE COLORADO RIVER
VALLEY...ESPECIALLY AS ANY WEAK DISTURBANCES MOVE DOWN THE BACKSIDE
OF THE TROUGH. OTHERWISE...SENSIBLE WEATHER WILL BE LIMITED TO
MOSTLY CLEAR SKIES AND A GRADUAL WARMING TREND ACROSS THE AREA. NEAR
NORMAL TEMPERATURES ARE EXPECTED FOR THE MIDDLE OF THE
WEEK...WARMING TO 3-5 DEGREES ABOVE NORMAL BY THE WEEKEND.
