AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
856 AM PDT SUN APR 24 2011

.SYNOPSIS...WEAK LOW PRESSURE OVER THE GREAT BASIN WILL KEEP A
CHANCE OF SHOWERS AND A SLIGHT CHANCE OF THUNDERSTORMS MAINLY OVER
EAST CENTRAL NEVADA AND NORTHERN MOHAVE COUNTY TODAY. STRONG WEST
WINDS WILL ALSO CONTINUE OVER THE WESTERN MOJAVE DESERT.
TEMPERATURES WILL GET A LITTLE WARMER TODAY AND MONDAY BEFORE A COLD
FRONT PASSES THROUGH MONDAY NIGHT...PRODUCING ANOTHER ROUND OF
STRONG WINDS WHILE USHERING IN COOLER TEMPERATURES FOR TUESDAY.
VERY WARM WEATHER WILL RETURN BY THURSDAY.
&&

.UPDATE...MOST OF THE FORECAST LOOKS RIGHT ON TARGET THIS MORNING.
ONLY CONCERN WAS THE BATCH OF CLOUDS ANCHORED TO THE SIERRA AND
ADVECTING OVER MUCH OF SAN BERNARDINO COUNTY THIS MORNING...BUT
THESE HAVE DETACHED FROM THE SIERRA AND SHOULD SHRED OUT BY NOON. NO
UPDATE PLANNED THIS MORNING.
&&

.PREV DISCUSSION...
327 AM PDT SUN APR 24 2011

.SHORT TERM...LAS VEGAS AND CEDAR CITY RADARS CONTINUE TO DETECT
LIGHT SHOWERS ACROSS LINCOLN COUNTY EARLY THIS MORNING. OVER THE
PAST 6 HOURS COYOTE WASH RAWS HAS REPORTED NEARLY A QUARTER OF AN
INCH OF RAIN WHILE IMMIGRATION WASH RAWS REPORTED 0.15 INCHES.
LINCOLN COUNTY AND NORTHERN MOHAVE COUNTY ARIZONA WILL CONTINUE TO
SEE LIGHT SHOWERS THROUGHOUT THE DAY AS AN ELONGATED LOBE OF
VORTICITY CROSSES THE AREA. MODELS INDICATE VERY LIMITED INSTABILITY
BUT CAN NOT RULE OUT THE POSSIBILITY OF A VERY ISOLATED
THUNDERSTORM. SHOWERS WILL END THIS EVENING AS THE DISTURBANCE
SHIFTS EAST INTO UTAH AND ARIZONA. THE NEXT SHORTWAVE TROUGH IS A
FAST MOVER AND IS A TAD FURTHER NORTH JUST GIVING A SHOT OF ISOLATED
THUNDERSTORMS TO FAR NORTHERN LINCOLN COUNTY MONDAY AFTERNOON.

OF MORE SIGNIFICANCE WILL BE THE CONTINUATION OF STRONG WINDS ACROSS
THE WESTERN MOJAVE DESERT. THERE HAS BEEN A SLIGHT LULL IN THE WINDS
ACROSS THE WESTERN MOJAVE DESERT OVERNIGHT WITH MOST GUSTS GENERALLY
LESS THAN 40 MPH. BY EARLY AFTERNOON...SURFACE PRESSURE GRADIENT
TIGHTENS BETWEEN EDWARDS AFB AND BAKER LEADING TO ENHANCED WEST
WINDS WITH GUSTS UP TO 55 MPH POSSIBLE. THE WIND ADVISORY IS IN
EFFECT UNTIL MIDNIGHT.

TWO NEW HIGH WIND WATCHES WILL BE ISSUED THIS MORNING AS WELL. THE
POTENTIAL FOR EVEN STRONGER WEST WINDS EXISTS STARTING MONDAY
AFTERNOON AND CONTINUING THROUGH THE EVENING IN THE LEE OF THE
SOUTHERN SIERRA NEVADA OF INYO COUNTY. HI RES 4KM NMM SHOWS GOOD
POTENTIAL OF DOWNSLOPE WINDS DEVELOPING WITH GUSTS EXCEEDING HIGH
WIND WARNING CRITERIA. THOSE STRONG WINDS WILL EVENTUALLY WORK SOUTH
AND IMPACT THE WESTERN MOJAVE DESERT MONDAY NIGHT. WIND GUIDANCE
NUMBERS FOR BARSTOW-DAGGETT ARE QUITE IMPRESSIVE AND FEEL A HIGH
WIND WATCH IS JUSTIFIED. A COLD FRONT ASSOCIATED WITH THE FAST
MOVING SHORTWAVE TROUGH WILL QUICKLY MOVE SOUTHEAST ACROSS THE AREA
MONDAY NIGHT WITH WINDS SHIFTING TO A NORTHERLY DIRECTION. WILL
PROBABLY NEED TO CONSIDER EITHER A WIND ADVISORY OR LAKE WIND
ADVISORY FOR THE LAKE MEAD NATL RECREATION AREA AND COLORADO RIVER
DUE TO THE STRONG NORTH WINDS.

.LONG TERM...NORTHWEST FLOW ALOFT IS EXPECTED TO BE IN PLACE
WEDNESDAY ALLOWING WHAT LOOKS LIKE A WEAK RIPPLE OF ENERGY TO MOVE
ACROSS THE AREA BRINGING SOME HIGH CLOUDS MAINLY TO THE NORTHERN
HALF OF THE AREA. THE MODELS ARE ALL IN GOOD AGREEMENT ON THURSDAY
AT BRINGING A CLOSED LOW ACROSS SOUTHWEST CANADA WHICH WILL RESULT
IN INCREASING SOUTHWEST FLOW ACROSS OUR AREA. 700 MB WINDS ONLY SHOW
20-30 KT VALUES...BUT BELIEVE WE SHOULD STILL SEE BREEZY TO WINDY
CONDITIONS THURSDAY AFTERNOON INTO THURSDAY NIGHT ACROSS THE ENTIRE
AREA WITH THE HIGHEST WINDS IN FAVORED SPOTS LIKE NW SAN BERNARDINO
COUNTY AND OVER THE EASTERN SLOPES OF THE SOUTHERN SIERRA. WITH THE
INCREASE IN SOUTHWEST FLOW HIGH TEMPS SHOULD GET CLOSE TO 10 DEGREES
ABOVE NORMAL ON THURSDAY AFTERNOON...PUSHING MOST LOWER MOJAVE
DESERT VALLEYS INTO THE 90S FOR HIGHS. AS THE LOW MOVES FURTHER EAST
ON FRIDAY THIS WILL LOWER HEIGHTS ACROSS THE AREA AND DROP HIGH
TEMPS BY ABOUT 5-7 DEGREES. THIS IS ALSO WHEN THE MODELS BEGAN TO
DIVERGE WITH HANDLING THE OVERALL PATTERN. FOR FRIDAY IT LOOKS LIKE
WE MAY GET A FEW SHOWERS RIGHT IN OR JUST NORTH OF LINCOLN AND
CENTRAL NYE COUNTIES ALONG THE TRAILING END OF A COLD FRONT. FOR NOW
I KEPT IN SOME SLIGHT CHANCE POPS IN NORTHERN LINCOLN COUNTY. WHILE
ALL MODELS EJECT THIS SYSTEM EASTWARD BY SATURDAY...THE 00Z
OPERATIONAL ECMWF BRINGS A SECOND PIECE OF ENERGY SOUTH BEHIND THIS
INITIAL LOW KEEPING NORTHWEST FLOW ALOFT IN PLACE THROUGH NEXT
WEEKEND. THE OPERATIONAL GFS...GFS ENSEMBLES AND GEM AS WELL AS THE
PREVIOUS TWO RUNS OF THE ECMWF SHOWED RIDGING QUICKLY BUILDING INTO
THE REGION IN THE UPPER LEVELS BY SATURDAY. I DID GO WITH A SLOWER
EJECTING OF THIS SYSTEM AS A TIP TO THE ECMWF...BUT GIVEN IT IS AN
OUTLIER I DID NOT FULLY BUY THIS NEW IDEA IT HAS. THUS THIS RESULTED
IN LINGERING A SLIGHT CHANCE OF SHOWERS IN LINCOLN COUNTY INTO
SATURDAY AFTERNOON AND ALSO SHOWING A SUBTLE DROP IN TEMPS FOR THE
WEEKEND AND KEEPING ANY WARMING TREND SLOW FROM SATURDAY INTO
SUNDAY. AFTERWARDS...THE GFS AND GEM AND MOST GFS ENSEMBLES BRING
ANOTHER TROUGH TOWARDS THE PAC NW/NORCAL BY LATE SUNDAY INTO NEXT
MONDAY WHILE THE ECMWF KEEPS THINGS DRY SINCE IT IS SLOWER TO EJECT
THE LATE THIS WEEK SYSTEM. FOR NOW...JUST INCREASED CLOUDS AND ADDED
IN A SLIGHT CHANCE OF SHOWERS IN THE NORTHWEST CWFA FOR NEXT MONDAY.

.AVIATION...FOR MCCARRAN...SOUTH TO SOUTH-SOUTHWEST WINDS SHOULD
INCREASE AGAIN AROUND 19Z TODAY WITH SPEEDS INCREASING TO 12-16 KTS
SUSTAINED WITH GUSTS OF 20-25 KTS. SPEEDS SHOULD BEGIN TO LESSEN
AROUND 04Z MONDAY. MAINLY SCT-BKN CLOUDS AOA 25K FEET THROUGH SUNDAY
NIGHT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SOUTHWEST TO WEST WINDS ACROSS THE AREA THROUGH THIS
AFTERNOON WITH SPEEDS INCREASING BETWEEN 17Z AND 19Z TODAY.
SUSTAINED WINDS OF 10-15 KTS WITH GUSTS UP TO 25 KTS WILL OCCUR IN
MOST AREAS EXCEPT IN NW SAN BERNARDINO COUNTY WHERE SUSTAINED WINDS
OF 20-30 KTS AND GUSTS UP TO 40 KTS CAN OCCUR. MAINLY NORTH WINDS AT
KBIH THROUGH TONIGHT AT 6-12 KTS EXCEPT THIS AFTERNOON WHEN SLIGHTLY
HIGHER WINDS WILL OCCUR. MAINLY SCT-BKN CLOUDS AOA 20K FEET EXCEPT
OVER THE SOUTHERN GREAT BASIN AND NORTHERN MOHAVE WHERE ISOLATED
SHRA AND HIGHER ELEVATION SHSN MAY OCCUR AND EVEN AN ISOLATED TSRA
COULD BE AROUND. CIGS AS LOW AS 5K-8K FEET WILL EXIST OVER THE
SOUTHERN GREAT BASIN AND NORTHERN MOHAVE COUNTY AT TIMES. MUCH
HIGHER WINDS LOOK TO OCCUR ON MONDAY ESPECIALLY TO THE LEE OF THE
SOUTHERN SIERRA NEVADA AND MECHANICAL TURBULENCE WILL BE POSSIBLE.
