AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
945 PM PDT THU JUN 10 2010

UPDATED AVIATION AND WWA SECTIONS

.SYNOPSIS...A PACIFIC STORM  MOVING TOWARDS THE GREAT BASIN THIS
EVENING AND FRIDAY AND BE CENTERED OVER THE AREA BY SATURDAY. THE
STORM WILL BRING GUSTY WINDS TONIGHT TO MOST OF THE AREA. SOME
ISOLATED SHOWERS AND THUNDERSTORMS ARE POSSIBLE OVER MOUNTAIN AREAS
FRIDAY AND SATURDAY ALONG WITH TEMPERATURES WELL BELOW AVERAGE. A
WARM UP WILL START ON SUNDAY AND INTO EARLY NEXT WEEK AS THE STORM
MOVES OUT OF THE AREA. &&

.UPDATE...HAVE UPDATED GRIDS TO INCREASE CLOUD COVER ASSOCIATED WITH
THE COLD FRONT AND UPPER LEVEL TROUGH. RH VALUES HAVE BEEN DROPPING
RAPIDLY THIS EVENING ACROSS MUCH OF THE CWA AND WITH WIND GUSTS IN
EXCESS OF 35 MPH EXPECTED TO CONTINUE ACROSS THE MOJAVE DESERT AND
PORTIONS OF SOUTHERN NEVADA I HAVE EXTENDED THE CURRENT RED FLAG
WARNING UNTIL MIDNIGHT. DOWNSLOPE POTENTIAL IN THE LEE OF THE SIERRA
HAS ENDED AND CANCELLED THE HIGH WIND WARNING FOR THE EASTERN
SIERRA AND OWENS VALLEY. THE WINDS HAVE GUSTED AT A FEW LOCATIONS IN
THE NORTHWEST PLATEAU AND NORTHWEST DESERTS OF ARIZONA...BUT THE
TREND IS DOWNWARD AND WILL ALLOW THE WIND ADVISORY TO EXPIRE AT 9PM.
BASED ON LATEST TRENDS AND LATEST GUIDANCE WILL ALSO CANCEL THE WIND
ADVISORY FOR ALL BUT THE MOJAVE DESERT OF SAN BERNARDINO COUNTY AT 9
PM.

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS EXPECTED THROUGH 08-10Z
WHEN A COLD FRONT WILL PUSH THROUGH THE VALLEY. WINDS WILL LIKELY
CONTINUE AT 12-18 KTS WITH GUSTS TO AROUND 20-25 KTS MOST OF THE
NIGHT. CLOUDS WILL BE SCT-BKN AOA 15-20K FEET OVERNIGHT. ON FRIDAY
EXPECT SCT CLOUDS AOA 12K FEET MAINLY IN THE AFTERNOON AND EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A COLD FRONT IS MOVING THROUGH THE AREA TONIGHT WITH
GUSTY SOUTHWEST TO WEST WINDS AHEAD OF THE FRONT...ACROSS THE
DESERTS...BECOMING NORTHWEST TO NORTH WINDS BEHIND IT. THE STRONGEST
WINDS WILL CONTINUE TO BE ACROSS THE DESERTS OF SAN BERNARDINO
COUNTY...WHERE GUSTS OF 40 KTS ARE POSSIBLE TONIGHT. WINDS WILL BE
NORTHERLY AT 8-16 KTS ACROSS MOST OF THE AREA ON FRIDAY EXCEPT WEST
AROUND KDAG. VARIABLE CLOUDS MAINLY AOA 15K FEET TONIGHT AND THEN
SCT-BKN CLOUDS AOA 10K-15K FEET ON FRIDAY. ISOLATED SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE OVER THE HIGHER TERRAIN MAINLY IN THE
SOUTHERN GREAT BASIN. &&

.PREV DISCUSSION...TODAY THROUGH SATURDAY NIGHT...NOT MUCH
CHANGE MADE TO FORECAST. WINDS ARE LATE IN RAMPING UP TO WIND
ADVISORY CRITERIA BUT ARE GETTING THERE THIS AFTERNOON. WILL LET THE
ADVISORIES RUN THEIR COURSE AND LET THE NEXT SHIFT LOOK AT ENDING
THEM EARLIER AS IT LOOKS LIKE THIS MAY BE THE CASE. THE PRESSURE
GRADIENT IS STARTING TO TIGHTEN AHEAD OF THE TROUGH DROPPING IN FROM
THE NORTHWEST. SO FAR THE BEST LOCATION FOR THE WINDS CONTINUE TO BE
WESTERN SAN BERNARDINO COUNTY. IN NEVADA IT WILL BE RIGHT ALONG THE
COLD FRONT AS IT MOVES THROUGH. IT LOOKS LIKE THE FRONT WILL BE
COMING THROUGH THE LAS VEGAS AREA AROUND 06-07Z. LOCAL HIGH
RESOLUTION MODELS DO SHOW A QUICK DROP OFF IN SPEED AFTER PASSAGE.

AFTER THE SURFACE TROUGH/FRONT PASSAGE WINDS AREA WIDE SLACKEN
CONSIDERABLY FROM EARLY FRIDAY ONWARDS. NEXT CONCERNS ARE FOR
TEMPERATURES AND PRECIPITATION CHANCES. THERE IS A GOOD
TEMPERATURE/THICKNESS CHANGE BROUGHT IN ESPECIALLY AS THE UPPER LOW
DEVELOPS RIGHT OVER SOUTHERN NEVADA. LOOKING TO GET AT OR VERY NEAR
RECORD LOW MAXIMUM TEMPERATURES FOR SATURDAY. HARD TO BELIEVE THIS
KIND OF SYSTEM IS HAPPENING SO LATE IN THE YEAR. BUT THE TEMPERATURE
RELIEF IS WELCOME. THE AREA SHOULD BEGIN TO WARM UP STARTING SUNDAY
AS THE LOW STARTS MOVING OUT TO THE NORTHEAST THEN.

WITH THE LOW OVERHEAD AND COLD AIR ALOFT LOOKING AT SOME LOW
STABILITY INDICES LATE FRIDAY INTO SATURDAY. STILL PROJECTING
LIMITED MOISTURE ASSOCIATED WITH LOW WITH THE BEST MOISTURE AND
INSTABILITY TO BE ON THE EAST AND NORTHEAST SIDE OF THE LOW CENTER.
DID INCREASE THE POPS AND COVERAGE A LITTLE OVER THE EAST AND
NORTHEAST CWA AND OVER THE SOUTHERN NEVADA MOUNTAINS.

.LONG TERM...BY SUNDAY AFTERNOON THE UPPER LOW IS SHOWN TO PULL AWAY
FROM THE AREA AND MOVE NORTHEAST TOWARDS WESTERN WYOMING. SOME
ENERGY DOES REMAIN ON THE BACK SIDE OF THE LOW HOWEVER THE WRF AND
GFS SHOW MUCH LESS SHOWER ACTIVITY ACROSS THE REGION THAN THE ECMWF
AS THEY ARE MUCH DRIER IN THE MID-LEVELS. GIVEN THE MODEL SPREAD AND
TO KEEP OUR BORDERS FRIENDLY WITH THE NEIGHBORS I HAVE OPTED TO
LEAVE IN A SLIGHT CHANCE FOR SHOWERS/THUNDERSTORMS ACROSS LINCOLN
AND NORTHERN MOHAVE COUNTIES ON SUNDAY AFTERNOON. TEMPS WILL REMAIN
BELOW NORMAL HOWEVER WESTERN AREAS WILL SEE SIGNIFICANT WARMING OVER
SATURDAY AS THE STRENGTH OF THE NORTHERLY FLOW ON THE BACK SIDE OF
THE LOW LESSENS THERE. A POSITIVELY TILTED SHORTWAVE RIDGE SLIDES
EASTWARD SUNDAY NIGHT INTO MONDAY FINALLY PUSHING THE UPPER LOW OUT
OF THE PICTURE. THIS WILL SHIFT THE FLOW TO MORE OF A WEST/SOUTHWEST
DIRECTION WHICH WILL BRING US A WARMING TREND ON MONDAY HOWEVER
HIGHS WILL STILL BE SOME 3 TO 5 DEGREES BELOW NORMAL.

BY TUESDAY A POSITIVELY TILTED UPPER TROUGH DROPS OUT OF BRITISH
COLUMBIA AND RACES SOUTHWARD ACROSS NEVADA AND CALIFORNIA LATE
TUESDAY INTO WEDNESDAY. WHAT LOOKS TO BE ANOTHER COLD FRONT IS EVEN
ACCOMPANIED BY SOME MID-LEVEL MOISTURE IN LINCOLN COUNTY COME THE
TUESDAY AFTERNOON AND THUS HAVE ADDED IN VERY LOW END SLIGHT CHANCE
POPS THERE THEN. THIS TROUGH AND ASSOCIATED FRONT SHOULD ALSO
INCREASE WINDS TO SOME EXTENT BUT 700 MB WINDS NOW ARE ONLY SHOWING
15 KTS OR SO THUS THE STRENGTH IS QUESTIONABLE. HOWEVER AFTER TEMPS
WARM TO AROUND NORMAL AHEAD OF THE FRONT ON TUESDAY THEY SHOULD DROP
A LITTLE ON WEDNESDAY BEHIND IT. ONCE THIS TROUGH MOVES BY MODELS
ALL SHOW A WEAK UPPER LOW MOVING NORTHEAST FROM THE PACIFIC ACROSS
SOCAL THURSDAY INTO FRIDAY. THIS FEATURE WILL LIKELY BRING US SOME
SORT OF CLOUDS THEN. TEMPS WILL REBOUND A LITTLE BUT IF CLOUDS ARE
MORE EXTENSIVE THEN EARLY APPEARANCES SHOW HIGH TEMPS MAY STAY FLAT
OR EVEN DROP A FEW DEGREES.
&&

.FIRE WEATHER...WINDS AND LOW HUMIDITIES WILL CONTINUE THROUGH THIS
EVENING IN SOUTHERN NEVADA/NEVADA/SOUTHEAST ARIZONA/NORTHWEST
ARIZONA WITH GUSTS TO OVER 35 MPH ACROSS MUCH OF THE AREA THIS
AFTERNOON AND EVENING. AFTERNOON RELATIVE HUMIDITIES ARE BELOW 15
PERCENT ACROSS THE DISTRICT TOO AND THIS COMBINED WITH THE DRY TO
VERY DRY FUELS ADDS UP TO A CRITICAL FIRE BEHAVIOR DAY. THE RED FLAG
WARNING CONTINUES TO BE IN EFFECT FOR NORTHWEST ARIZONA EXTREME
SOUTHERN NEVADA AND SAN BERNARDINO THROUGH THIS EVENING. AS THE LOW
SHIFTS INTO THE DISTRICT ON FRIDAY AND SATURDAY...COOLER
TEMPERATURES AND LESS WIND WILL OCCUR.  &&

.VEF WATCHES/WARNINGS/ADVISORIES...
NV...RED FLAG WARNING UNTIL 2 AM PDT FRIDAY FOR NVZ465.
AZ...NONE.
CA...RED FLAG WARNING UNTIL 2 AM PDT FRIDAY FOR CAZ228.
     WIND ADVISORY UNTIL 2 AM PDT FRIDAY FOR CAZ524.
