NATIONAL WEATHER SERVICE LAS VEGAS NV
925 AM PDT SUN MAY 19 2013
.SYNOPSIS...AN UPPER LEVEL DISTURBANCE WILL PRODUCE SCATTERED
SHOWERS AND A FEW THUNDERSTORMS OVER EAST CENTRAL NEVADA TODAY WHILE
DRY AND MILD CONDITIONS CONTINUE ACROSS THE REST OF THE REGION. A
WEAK COLD FRONT WILL THEN BRING LOCAL GUSTY NORTH WINDS TONIGHT
AND MONDAY WITH SLIGHTLY COOLER TEMPERATURES. A STORM MOVING INTO
THE PACIFIC NORTHWEST BY TUESDAY WILL BRING PERSISTENT BREEZY
CONDITIONS TO THE REGION FROM MID WEEK INTO THE HOLIDAY WEEKEND
WITH TEMPERATURES NEAR SEASONAL NORMALS.
&&
.UPDATE...NORTHWEST FLOW ALOFT TO REMAIN ACROSS THE CWA TODAY AS A
WEAK TROUGH MOVES ACROSS NORTHERN NEVADA AND INTO UTAH. THIS SYSTEM
WILL BRUSH ACROSS THE LINCOLN COUNTY PANHANDLE RESULTING IN A SLIGHT
CHANCE OF SHOWERS/AFTERNOON THUNDERSTORMS TODAY...HOWEVER THE
REMAINDER OF THE CWA WILL CONTINUE TO SEE DRY CONDITIONS. OVERALL
THE CURRENT SHORT TERM FORECAST IS ON TRACK AND DO NOT PLAN ANY
UPDATES THIS MORNING.
&&
.AVIATION...FOR MCCARRAN...NORTHERLY WINDS GENERALLY AROUND 10KT
WITH GUSTS TO NEAR 20KT...BECOMING 8-12KTS AFT 02Z AND CONTINUING
THROUGH MUCH OF MONDAY. FEW-SCT CLOUDS AROUND 10K FEET THIS
AFTERNOON AND EVENING AND THERE WILL BE A SLIGHT CHANCE OF A SHOWER
OR THUNDERSTORM IN THE MORMON MESA CORRIDOR. SKIES BECOMING
GENERALLY CLEAR OVERNIGHT INTO MONDAY.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS OVER MUCH OF THE AREA WILL BE WEST TO NORTHWEST
THROUGH MUCH OF TODAY AS A WEAK SYSTEM PASSES THROUGH THE AREA. MOST
AREAS WILL SEE WIND SPEEDS 10-15 KTS WITH A FEW LOCATIONS SEEING
WINDS UP TO 20 KTS. LINCOLN COUNTY WILL SEE THE GREATEST COVERAGE OF
CLOUDS WITH MAINLY SCT-BKN 10-12K FEET AND A SLIGHT CHANCE OF A
THUNDERSTORM. THE REMAINDER OF THE AREA WILL SEE SKC-FEW120.

340 AM PDT SUN MAY 19 2013
.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...THE FORECAST AREA WILL
REMAIN UNDER A NORTHWEST FLOW ALOFT ON THE BACK SIDE OF A BROAD
TROUGH ROLLING ACROSS THE ROCKY MOUNTAIN STATES INTO THE PLAINS.
THIS WILL ALLOW DISTURBANCES TO SLIDE DOWN THROUGH THE GREAT BASIN
TODAY AND TONIGHT. A DISTURBANCE COULD BE SEEN ON SATELLITE LOOPS
EXTENDING OVER NORTHERN NEVADA THIS MORNING WITH ADDITIONAL ENERGY
UPSTREAM ACROSS WESTERN OREGON AND WASHINGTON. THE LATEST
OPERATIONAL MODELS ARE IN GOOD AGREEMENT AT TRACKING THIS ENERGY
ACROSS EASTERN NEVADA AND SOUTHWEST UTAH THIS AFTERNOON AND TONIGHT
BEFORE IT DIVES INTO ARIZONA AND NEW MEXICO EARLY MONDAY. SUFFICIENT
MID LEVEL MOISTURE...INSTABILITY AND DYNAMIC SUPPORT WILL BE OVER
NORTHERN AND EASTERN LINCOLN COUNTY TO PRODUCE ISOLATED TO SCATTERED
SHOWERS AND A FEW THUNDERSTORMS. CONVECTION WILL END THIS EVENING AS
A DRY FRONT PUSHES DOWN THROUGH THE SOUTHERN GREAT BASIN AND MOJAVE
DESERT TONIGHT WITH NORTH WINDS DEVELOPING BEHIND IT. THE LATEST
HIGH RESOLUTION MODELS INDICATE SPEEDS WILL GENERALLY BE IN THE
15-25 MPH RANGE. WINDS WILL BE STRONGER DOWN THE COLORADO RIVER
VALLEY AND PERSISTENT GUSTS AROUND 35 MPH WILL BE POSSIBLE FROM
LAUGHLIN TO NEEDLES MONDAY MORNING THROUGH EARLY AFTERNOON. THIS
WILL CREATE FIRE WEATHER CONCERNS FOR THIS AREA AND A FIRE WEATHER
WATCH REMAINS IN EFFECT. WIND SPEEDS SHOULD DECREASE FAIRLY QUICKLY
MONDAY AFTERNOON AS THE SURFACE PRESSURE GRADIENT RELAXES ALONG THE
EASTERN NEVADA BORDER AND A SHORTWAVE RIDGE BETWEEN LOW PRESSURE
SYSTEMS MOVES OVERHEAD MONDAY NIGHT AND EARLY TUESDAY. ATTENTION
WILL THEN TURN TO A DEEP LOW PRESSURE SYSTEM AS IT DROPS INTO THE
PACIFIC NORTHWEST AND BRUSHES NORTHWEST NEVADA TUESDAY NIGHT. HIGH
TEMPERATURES WILL ONLY VARY 3-5 DEGREES DURING THE PERIOD.
.LONG TERM...MODELS IN GOOD AGREEMENT IN SHOWING A DEEP AREA OF LOW
PRESSURE REMAINING NEARLY STATIONARY OVER OREGON WEDNESDAY THROUGH
FRIDAY. THE MAIN IMPACTS FROM THIS SYSTEM FOR OUR AREA WILL BE A
FAIRLY LONG PERIOD OF GUSTY SOUTHWEST WINDS. WE REALLY ARE NOT
EXPECTING TO SEE MUCH OF A TEMPERATURE DROP WITH THIS
SYSTEM...EXCEPT POSSIBLY THE FAR NORTHWEST PORTIONS OF THE CWA. THE
REMAINDER OF THE AREA WILL CONTINUE TO SEE TEMPERATURES A FEW
DEGREES ABOVE NORMAL. PRECIPITATION ALSO LOOKS TO REMAIN NORTH OF
THE AREA AND THE GUSTY WINDS AND DRY CONDITIONS WILL LEAD TO AN
INCREASED CONCERN FOR FIRE WEATHER HAZARDS. BY FRIDAY NIGHT THIS LOW
IS FORECAST TO LIFT NORTHEAST WITH A BAGGY WEAK TROUGH REMAINING
OVER THE WEST COAST THROUGH THE WEEKEND. THIS SHOULD BRING LIGHTER
WINDS TO THE AREA...BUT KEEP TEMPERATURES A FEW DEGREES ABOVE
NORMAL.
&&
.FIRE WEATHER...A DRY COLD FRONT WILL PUSH DOWN THROUGH SOUTHERN
NEVADA AND NORTHWEST ARIZONA SUNDAY NIGHT/EARLY MONDAY. THIS WILL
BRING MODERATE NORTH WINDS TO MUCH OF THE REGION WITH THE STRONGEST
WINDS ALONG THE COLORADO RIVER VALLEY. WIND GUSTS TO NEAR 40 MPH ARE
POSSIBLE ALONG THE STRETCH FROM LAUGHLIN-BULLHEAD CITY TO NEEDLES
LATE MONDAY MORNING THROUGH EARLY AFTERNOON. THIS WILL CREATE THE
POTENTIAL FOR CRITICAL FIRE WEATHER CONDITION AS RELATIVE HUMIDITY
VALUES FALL BELOW 15 PERCENT. A FIRE WEATHER WATCH IS IN EFFECT FOR
THIS PERIOD FOR THE COLORADO RIVER ZONES.

933 PM PDT SAT MAY 18 2013
.SYNOPSIS...TEMPERATURES WILL CONTINUE TO WARM ON SUNDAY AS
GENERALLY DRY FLOW REMAINS OVER THE AREA. HOWEVER A WEAK COLD FRONT
WILL BRING LOCAL GUSTY NORTH WINDS TO THE REGION ON MONDAY WITH
SLIGHTLY COOLER TEMPERATURES. A STORM MOVING INTO THE PACIFIC
NORTHWEST BY WEDNESDAY WILL THEN BRING LOCALLY BREEZY CONDITIONS TO
THE REGION THROUGH MUCH OF NEXT WEEK WITH TEMPERATURES BEING NEAR
NORMAL.
&&
.UPDATE...UPPER LEVEL DISTURBANCES EMBEDDED IN NORTHWEST FLOW WILL
KEEP SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS GOING THROUGH THE
NIGHT ACROSS NORTHERN NEVADA AND PARTS OF UTAH. A PORTION OF LINCOLN
COUNTY...NORTH AND EAST OF PANACA...MAY SEE AN ISOLATED SHOWER OR
THUNDERSTORM SUNDAY ALONG A COLD FRONT AND UNDER REGION OF
DIVERGENCE ALOFT ASSOCIATED WITH 95 KT NORTHWESTERLY JET. NO UPDATE
NECESSARY.
&&
.AVIATION...FOR MCCARRAN...WINDS WILL GENERALLY FAVOR A
SOUTHWESTERLY DIRECTION UP TO 10 KTS THROUGH SUNDAY WITH A FEW
HIGHER GUSTS AT TIMES. A FEW LIGHT SHOWERS WILL REMAIN NEAR THE
MORMON MESA CORRIDOR THROUGH MIDNIGHT. A FEW CLOUDS AROUND 12K FEET
AGAIN SUNDAY AFTERNOON WITH A SLIGHT CHANCE OF A SHOWER OR
THUNDERSTORM IN THE MORMON MESA CORRIDOR.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A WEAK SYSTEM WILL MOVE THROUGH THE GREAT BASIN TONIGHT
AND SUNDAY RESULTING IN GUSTY WEST TO NORTHWEST WINDS OF 20-25KTS.
THE EXCEPTION WILL BE SOUTH TO SOUTHWEST WINDS ACROSS THE MOJAVE
DESERT REGION UNTIL LATER SUNDAY WHEN A COLD FRONT WILL TURN WINDS
MORE WESTERLY IN THESE AREAS AS WELL. CLEAR CONDITIONS IN THE WEST
WITH FEW-SCT CLOUDS BETWEEN 10-12K FEET. BASE COULD BE LOWER WHEN
ASSOCIATED WITH ANY THUNDERSTORM THAT DEVELOPS...MAINLY OVER LINCOLN
AND NORTHERN MOHAVE COUNTY.
&&
.PREV DISCUSSION...
308 PM PDT SAT MAY 18 2013
.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT...FOR THE REMAINDER OF
THE AFTERNOON...DRYING AND STABILIZING CONDITIONS WILL CONTINUE TO
BE SEEN ACROSS LINCOLN AND MOHAVE COUNTY AS THE MAIN DYNAMICS FOR
ANY SHOWERS/THUNDERSTORMS HAS SHIFTED TO MAINLY SOUTHERN UTAH AND
EAST OF MOHAVE COUNTY.
THE NEXT WEAK STORM WILL BE DROPPING SOUTHEAST INTO NORTHERN NEVADA
TONIGHT AND ACROSS UTAH ON SUNDAY WITH A WEAK COLD FRONT MOVING
ACROSS EXTREME SOUTHERN NEVADA SUNDAY NIGHT. THE MAIN IMPACT FROM
THIS SYSTEM WILL BE NORTH WINDS BEHIND THE FRONT AS LIMITED
MOISTURE/INSTABILITY WILL BE SEEN OVER THE CWA. THE STRONGEST WINDS
WILL BE ON MONDAY IN THE NORTH WIND PRONE AREAS...ESPECIALLY THE
COLORADO RIVER VALLEY. GUSTS TO NEAR 40 MPH MAY BE SEEN ON MONDAY
WHICH WILL BE BELOW WIND ADVISORY CRITERIA...BUT MAY CREATE FIRE
WEATHER PROBLEMS. PLEASE SEE THE FIRE WEATHER SECTION BELOW. WINDS
WILL BE DECREASING LATE MONDAY AFTERNOON AS THE STORM CONTINUES TO
SHIFT EAST...WHILE DRY NORTHWEST FLOW ALOFT SETS UP OVER THE CWA ON
TUESDAY. THIS FLOW THEN SHIFTS TO THE SOUTHWEST BY TUESDAY NIGHT AS
A PACIFIC LOW MOVES ONTO THE PACIFIC NORTHWEST COAST.
TEMPERATURES ARE EXPECTED TO BE NEAR TO SLIGHTLY ABOVE NORMAL
THROUGH THE PERIOD WITH TUESDAY BEING THE WARMEST DAY DURING THE
SHORT TERM.
.LONG TERM...LOW PRESSURE WILL SIT OVER THE PACIFIC NORTHWEST
THROUGH MUCH OF THE WEEK...MAINTAINING A SOUTHWEST FLOW INTO THE
AREA. THIS PATTERN SHOULD RESULT IN MAINLY DRY CONDITIONS...A FEW
HIGH CLOUDS FROM TIME TO TIME AND NEAR NORMAL TEMPERATURES. THE MAIN
WEATHER CONCERN WILL BE WIND STRENGTH AS VARIOUS SHORTWAVES ROUND
THE BASE OF THE LOW AND EJECT INLAND. DEPENDING ON HOW FAR SOUTH
EACH SHORTWAVE EXTENDS...WILL DETERMINE THE STRENGTH OF WIND
EXPECTED WITHIN THE CWA. TAKING A LOOK AT GFS PROGS FOR THE
COMBINATION OF LOW RELATIVE HUMIDITY AND WIND SPEED...FIRE GROWTH
POTENTIAL COULD BE A CONCERN ALMOST EVERY AFTERNOON WEDNESDAY AND
BEYOND OVER SOME PORTION OF THE FORECAST AREA. DETAILS ON THIS
EVOLVING PATTERN WILL BECOME MORE CLEAR AS THE EVENT APPROACHES BUT
FOR NOW...EXPECT BREEZY TO WINDY CONDITIONS AND SEASONAL
TEMPERATURES DURING THE MID TO LATE WEEK PERIOD.
&&
.FIRE WEATHER...A WEAK STORM SYSTEM MOVING SOUTHEAST MAINLY ACROSS
UTAH LATE SUNDAY/SUNDAY NIGHT WILL MOVE A WEAK COLD FRONT ACROSS THE
DISTRICT SUNDAY NIGHT/EARLY MONDAY. THIS WILL ALLOW NORTH WINDS TO
FORM ACROSS MUCH OF THE REGION ON MONDAY WITH THE STRONGEST WINDS
BEING ALONG THE COLORADO RIVER. WIND GUSTS TO NEAR 40 MPH IN THIS
AREA ALONG WITH RELATIVE HUMIDITY VALUES DROPPING TO BELOW 15
PERCENT AND DRY FUELS MAY COMBINE TO CREATE HAZARDOUS FIRE

.UPDATE...OVERALL THE SHORT TERM FORECAST IS IN GOOD SHAPE. ENOUGH
DYNAMICS LEFT OVER FROM THE DEPARTING TROUGH TO FORM CUMULUS OVER
THE MOUNAINS OF MAINLY LINCOLN/NORTHERN MOHAVE COUNTY TODAY WITH A
SLIGHT CHANCE OF A SHOWER/THUNDERSTORMS LATE THIS MORNING INTO THE
AFTERNOON WHICH IS COVERED WELL. ONE MINOR CONCERN IS THE MOUNTAINS
OF EXTREME SOUTHERN NEVADA AS CUMULUS HAVE ALREADY FORMED OVER THE
SPRING MOUNTAINS ALSO. WILL MONITOR FOR NOW AS BELIEVE DRIER/MORE
STABLE AIR TO MOVE OVER THE AREA BY THIS AFTERNOON SO WILL CONTINUE
WITH THE CURRENT NON-SHOWER/THUNDERSTORM FORECAST FOR THIS AREA.

THE AREA BEHIND THE EXITING TROUGH TODAY AND SUNDAY THOUGH SOME
MOISTURE AND INSTABILITY WILL LINGER NEAR NORTHERN LINCOLN COUNTY. A
FAST MOVING SHORTWAVE TROUGH CURRENTLY APPROACHING THE PACIFIC
NORTHWEST IS FORECAST TO SLIDE ACROSS NORTHEAST NEVADA TONIGHT THEN
OVER UTAH AND THE FOUR CORNERS REGION SUNDAY AND SUNDAY NIGHT.
ISOLATED SHOWERS WILL BE POSSIBLE OVER NORTHERN LINCOLN COUNTY
THROUGH THE WEEKEND BUT THE MAIN EFFECT OF THIS SYSTEM WILL BE TO
DRAG A WEAK COLD FRONT DOWN THROUGH THE FORECAST AREA SUNDAY
AFTERNOON AND SUNDAY NIGHT. A ROUND OF NORTH BREEZES WILL FOLLOW
WITH ENHANCED WINDS DOWN THE COLORADO RIVER VALLEY ESPECIALLY MONDAY
MORNING. WILL NEED TO KEEP A WATCH ON WIND SPEEDS AS THE LOW

WIND SPEEDS SHOULD REMAIN BELOW ADVISORY LEVELS. WINDS WILL DIMINISH
MONDAY AFTERNOON AND MONDAY NIGHT AS A SHORTWAVE RIDGE MOVES
OVERHEAD. HIGH TEMPERATURES WILL ONLY VARY A FEW DEGREES DURING THE

SOUTHWEST WINDS OVER THE AREA EACH DAY. ALTHOUGH HEIGHTS WILL DROP
SOMEWHAT EACH DAY THE COLDER AIR IS NOT FORECAST TO DROP SOUTH AND
TEMPERATURES WILL STILL REMAIN A FEW DEGREES ABOVE NORMAL THROUGH
THE END OF THE WEEK. ITS POSSIBLE THAT A FEW SHOWERS MAY DEVELOP
OVER THE FAR NORTHERN PORTIONS OF THE CWA...BUT AS IT LOOKS NOW
CONDITIONS WILL REMAIN DRY THROUGH THE EXTENDED. THE MODELS THEN

EVENING WITH A BAND OF SHOWERS AND ISOLATED THUNDERSTORMS ACROSS
EASTERN AND SOUTHERN LINCOLN COUNTY AND INTO NYE COUNTY. A FEW
SHOWERS WERE JUST BEGINNING TO POP UP IN NORTHERN CLARK COUNTY AND
THE SPRING MOUNTAINS AS OF 9 PM AS WELL. STILL DO NOT EXPECTED ANY
SHOWERS OR THUNDERSTORMS TO WORK INTO THE LAS VEGAS VALLEY BUT THEY
COULD GET PRETTY CLOSE TO THE NORTHERN FRINGES OF THE VALLEY.
OVERALL THE PRECIPITATION WITH THE SHOWERS AND THUNDERSTORMS HAVE
BEEN PRETTY LIGHT AND OUTFLOW WINDS HAVE NOT BEEN TOO BAD EITHER
WITH MAYBE SOME GUSTS NEAR 20 MPH. THE INHERITED FORECAST HANDLES
THE CURRENT TRENDS PRETTY WELL SO FAR AND UPDATES ARE NOT PLANNED
THIS EVENING.

.PREV DISCUSSION...
315 PM PDT FRI MAY 17 2013
.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT...A WEAK TROUGH
TRANSITIONING WEST TO EAST ACROSS THE CWA HAS RESULTED IN ISOLATED
THUNDERSTORMS OVER MAINLY THE NORTHERN PORTION OF LINCOLN COUNTY
THIS AFTERNOON. HOWEVER THERE STILL REMAINS A SLIGHT CHANCE OF
SHOWERS/THUNDERSTORMS OVER MUCH OF THE NORTHERN MOUNTAINS THROUGH
THIS EVENING. AS THE TROUGH EXITS EAST TONIGHT...DRYING WILL BE SEEN
FROM THE WEST WITH GENERALLY DRY NORTHWEST FLOW ALOFT OVER THE AREA
ON SATURDAY. A SECOND WEAK SYSTEM IS FORECAST TO DROP SOUTHEAST INTO
UTAH LATE SATURDAY AND SUNDAY...BUT THE BEST MOISTURE/DYNAMICS WITH
THIS SYSTEM SHOULD REMAIN NORTH AND EAST OF OUR AREA. THE MAIN
IMPACT FROM THIS STORM WILL BE A WEAK COLD FRONT WHICH SHOULD MOVE
ACROSS THE DISTRICT EARLY SUNDAY NIGHT RESULTING IN WINDS TURNING TO
THE NORTH SUNDAY NIGHT AND MONDAY. HOWEVER AT THIS TIME WINDS APPEAR
TO ONLY BE IN THE BREEZY TO LOCALLY WINDY CATEGORY WITH THE WINDY
CONDITIONS BEING ALONG THE COLORADO RIVER VALLEY. DRY NORTH TO
NORTHWEST FLOW WILL THEN BE OVER THE CWA MONDAY AND MONDAY NIGHT.
UNDER THE DRY CONDITIONS TEMPERATURES WILL WARM A FEW DEGREES ON
SATURDAY AND AN ADDITIONAL DEGREE OR TWO ON SUNDAY RESULTING IN NEAR
NORMAL READINGS ON SUNDAY. ALTHOUGH THE WEAK COLD FRONT IS
EXPECTED THROUGH THE AREA SUNDAY NIGHT...LITTLE IMPACT ON
TEMPERATURES IS EXPECTED SO NEAR NORMAL READINGS WILL ALSO BE SEEN
ON MONDAY.
.LONG TERM...DRY AND BREEZY CONDITIONS ARE EXPECTED FOR MUCH OF NEXT
WEEK AS A STRONG UPPER LOW ANCHORS ITSELF OVER THE PACIFIC
NORTHWEST. THIS WILL LEAVE THE FORECAST AREA UNDER A SOUTHWEST FLOW
PATTERN TUES THROUGH AT LEAST FRIDAY THAT WILL BE FAVORABLE FOR
ENHANCED WINDS AND POTENTIALLY INCREASING FIRE DANGER AS FUELS
CONTINUE TO DRY. BY THE END OF THE WEEK...THE LOW MAY HAVE WORKED
ITS WAY FAR ENOUGH SOUTH TO INITIATE A FEW SHOWERS ACROSS THE
NORTHERN ZONES. BUT FOR NOW...MAINTAINED A DRY FORECAST.
TEMPERATURES ARE EXPECTED TO REMAIN SEVERAL DEGREES ABOVE NORMAL
TUESDAY...COOL A FEW DEGREES TO NEAR NORMAL WEDNESDAY AND THEN BELOW
NORMAL THURSDAY AND FRIDAY AS THE LOW SLOWLY SHIFTS SOUTH. THE
OVERALL FLOW WILL FAVOR PERIODS OF HIGH CLOUDS PASSING ACROSS THE
AREA AS WELL...WITH POTENTIALLY INCREASING CLOUD COVER BY THE END OF
THE WEEK.

.AVIATION...FOR MCCARRAN...SURFACE WINDS ARE EXPECTED TO REMAIN OUT

.UPDATE...THE BAND OF CLOUDS MENTIONED IN THE PREVIOUS DISCUSSION
HAS SHIFTED TO MAINLY OVER THE EASTERN PORTION OF THE CWA...
GENERALLY LINCOLN COUNTY THEN SOUTH OF INTERSTATE 15 THIS MORNING.
THIS MAY HAMPER HEATING SOMEWHAT...BUT EXPECT BAND TO CONTINUE
SHIFTING EAST DURING THE DAY ALLOWING FOR HEATING THIS AFTERNOON.
SHOWERS/THUNDERSTORMS STILL LOOK GOOD MAINLY OVER THE NORTHERN
MOUNTAINS WHILE WINDS SHOULD REMAIN BELOW ADVISORY LEVELS. OVERALL
THE SHORT TERM FORECAST REMAINS ON TRACK AND DO NOT PLAN ON ANY
UPDATES THIS MORNING.

.PREV DISCUSSION...
340 AM PDT FRI MAY 17 2013
.SHORT TERM...TODAY THROUGH SUNDAY NIGHT...THE INCOMING TROUGH WAS
CENTERED OVER CALIFORNIA THIS MORNING AND THE AXIS IS FORECAST TO BE
OVER CENTRAL AND SOUTHERN NEVADA BY THIS AFTERNOON. GUSTY SOUTHWEST
WINDS WERE PERSISTING ACROSS THE MOJAVE DESERT REGION BUT THE LATEST
HIGH RESOLUTION MODELS AND MOS GUIDANCE NOW INDICATE GUSTS WILL
REMAIN BELOW 40 MPH ACROSS NORTHWEST SAN BERNARDINO COUNTY. THE WIND
ADVISORY WAS CANCELLED ACCORDINGLY. A BAND OF MID AND HIGH CLOUDS
OVER MUCH OF THE FORECAST AREA WAS ENHANCING ALONG THE LEADING EDGE
OF THE SYSTEM AND WILL SLOWLY SHIFT TO THE EAST DURING THE DAY.
MOISTURE AND INSTABILITY ASSOCIATED WITH THE COLD POOL WAS WORKING
ITS WAY ACROSS NORTHERN INYO AND ESMERALDA COUNTIES EARLY THIS
MORNING. MODELS CONTINUE TO INDICATE THE POTENTIAL FOR SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS ACROSS THE SOUTHERN SIERRA AND
SOUTHERN GREAT BASIN. A FEW SHOWERS WILL ALSO BE POSSIBLE FOR THE
SPRING MOUNTAINS AND SHEEP RANGE. NO SIGNIFICANT CHANGES WERE MADE
TO POP VALUES AND WEATHER. TEMPERATURES SHOULD RUN ABOUT 8-10
DEGREES LOWER THAN THOSE OBSERVED THURSDAY.
AS THE TROUGH SHIFTS EAST TONIGHT...DRY NORTHWEST FLOW WILL DEVELOP
OVER THE REGION WITH TEMPERATURES CLIMBING A FEW DEGREES SATURDAY. A
SHORTWAVE TROUGH WILL THEN SLIDE FROM THE PACIFIC NORTHWEST ACROSS
THE NORTHERN GREAT BASIN AND INTERMOUNTAIN REGION SATURDAY NIGHT
THROUGH AND SUNDAY. THE MAIN INFLUENCE OF THE SYSTEM WILL BE FELT
SUNDAY NIGHT INTO MONDAY AS NORTH WINDS PUSH DOWN THROUGH SOUTHERN
NEVADA AND SURROUNDING AREAS...ESPECIALLY THE COLORADO RIVER VALLEY.
.LONG TERM...NOT MUCH CHANGE NEEDED TO THE EXTENDED AS MODELS REMAIN
IN FAIRLY GOOD AGREEMENT. A SHORTWAVE RIDGE WILL BUILD IN NORTH OF
THE REGION ON MONDAY AND RESULT IN BREEZY NORTH WINDS AS THE
NORTH/SOUTH SURFACE GRADIENT TIGHTENS. LOCATIONS DOWN ALONG THE
COLORADO RIVER VALLEY WILL SEE NORTH WINDS 15-30 MPH ON MONDAY.
TUESDAY WILL SEE LESS WIND AND WARMER TEMPERATURES WITH THE RIDGE
OVERHEAD...BUT A DEEP AREA OF LOW PRESSURE DROPPING DOWN OVER THE
PACIFIC NORTHWEST WILL QUICKLY RESULT IN WINDS PICKING BACK UP
ACROSS THE MOJAVE DESERT BY LATE TUESDAY AFTERNOON. THIS PATTERN IS
THEN EXPECTED TO STAY FAIRLY STAGNANT THROUGH THE WEEK...BUT
THURSDAY AND FRIDAY LOOK TO BE THE DAYS WITH STRONGEST WINDS AS THE
TROUGH DEEPENS OVER THE WESTERN US. A GRADUAL COOLING TREND IN
TEMPERATURES WILL OCCUR TUESDAY THROUGH FRIDAY AS THE TROUGH SLOWLY
SHIFTS SOUTH...BUT ONLY DOWN TO SEVERAL DEGREES BELOW NORMAL BY
FRIDAY.
.AVIATION...FOR MCCARRAN...SURFACE WINDS ARE EXPECTED TO REMAIN OUT
OF THE SOUTHWEST THROUGH THE DAY WITH MAX GUSTS UP TO 30KTS AND
AVERAGE GUSTS BETWEEN 20 AND 25KTS AS A LOW PRESSURE SYSTEM PASSES
OVER THE AREA. NO PRECIPITATION OR CLOUD COVERAGE THAT WOULD IMPACT
ARRIVAL RATES...WITH THE LOWEST CIGS EXPECTED AOA 12KFT DURING THE
LATE MORNING. WINDS WILL BEGIN TO DIMINISH IN THE EVENING...AND DROP
BELOW 10KTS BETWEEN 04Z AND 08Z.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SOUTHWEST WINDS OF 15-25 KNOTS WILL CONTINUE TODAY
ACROSS MUCH OF THE AREA EXCEPT INYO AND ESMERALDA AND CENTRAL NYE
COUNTIES AS A TROUGH OF LOW PRESSURE PASSES ACROSS THE REGION.
SCATTERED SHOWERS ARE EXPECTED TO REMAIN MAINLY OVER THE HIGHER
ELEVATIONS OF LINCOLN...CLARK...AND CENTRAL NYE COUNTIES. BASES AS
LOW AS 5K-8K FEET WILL BE POSSIBLE IN AND NEAR ANY SHOWERS.
OTHERWISE EXPECT MAINLY SCT-BKN CLOUDS AOA 18K-25K FEET WITH FEW-SCT
CLOUDS AS LOW AS 8K-12K FEET.
&&
.FIRE WEATHER...SOUTHWEST WINDS OF 15 TO 25 MPH CAN BE EXPECTED
ACROSS THE MOJAVE DESERT TODAY AS A LOW PRESSURE TROUGH MOVES THE
OVER THE REGION. THIS SYSTEM WILL PROVIDE LOWER TEMPERATURES AND

IN EFFECT THROUGH FRIDAY EVENING. WINDS WILL LIKELY BE BELOW
ADVISORY LEVEL MUCH OF THE OVERNIGHT HOURS AND EARLY FRIDAY BUT LOOK

254 PM PDT THU MAY 16 2013
.SHORT TERM...SATELLITE LOOPS CONTINUE TO SHOW INCREASING CLOUDS
ACROSS THE NORTHWESTERN HALF OF THE FORECAST AREA AS A TROUGH
CONTINUES TO DIG SOUTH ALONG THE WEST COAST. WINDS HAVE BEEN A BIT
SLOW TO GET GOING THIS AFTERNOON BUT HAVE BEGUN TO NEAR ADVISORY
CRITERIA. WILL KEEP ALL WINDS AND FIRE HIGHLIGHTS IN PLACE FOR THE

WINDS SHOULD BEGIN TO TAPER OFF AFTER 03Z ACROSS THE REGION. SHOWERS
ARE EXPECTED TO DEVELOP OVERNIGHT ACROSS THE HIGHER ELEVATIONS OF
ESMERALDA AND NORTHERN INYO COUNTIES BEFORE SPREADING ACROSS LINCOLN
AND NORTHERN/CENTRAL NYE COUNTIES FRIDAY MORNING. 12Z GUIDANCE
CONTINUED TO SHOW THE POTENTIAL FOR SHOWERS IN THE SPRING AND SHEEP
MOUNTAINS OF CLARK COUNTY AS WELL AS THE HIGH ELEVATIONS OF NORTHERN
MOHAVE. AS A RESULT I DID BUMP UP POPS SLIGHTLY IN THESE LOCATIONS.
SHOWER ACTIVITY SHOULD BEGIN TO WANE FRIDAY NIGHT AS THE TROUGH AXIS
MOVES WEST OF THE FORECAST AREA...LEAVING COOLER NORTH WINDS IN ITS
WAKE. SATURDAY AND SATURDAY NIGHT WILL FEATURE CLEARING
SKIES...WARMER TEMPERATURES...CALMER WINDS...AND DRIER CONDITIONS.
.LONG TERM...WHILE THIS SPRING HAS NOT BEEN AS WINDY WE MAY MAKE UP
FOR THIS NEXT WEEK. ANOTHER AREA OF LOW PRESSURE IS EXPECTED TO MOVE
SOUTHEAST ACROSS THE NORTHERN GREAT BASIN ON SUNDAY WHICH SHOULD
BRING A PUSH OF NORTHWEST TO NORTH WINDS BEHIND IT AS WELL AS LOWER
HEIGHTS ENOUGH THAT TEMPS MAY DROP A FEW DEGREES ON MONDAY MAINLY
OVER THE SOUTHERN GREAT BASIN. AS A SURFACE HIGH MOVES SOUTH ACROSS
IDAHO SUNDAY NIGHT INTO MONDAY IT SHOULD TIGHTEN UP SURFACE PRESSURE
GRADIENTS FROM THE NORTH TO SOUTH ENOUGH TO GENERATE NORTH WINDS
SUSTAINED AT 20-30 MPH WITH GUSTS TO NEAR 40 MPH ON MONDAY IN THE
COLORADO RIVER VALLEY MAINLY IN THE LAUGHLIN-BULLHEAD CITY AREA.
WINDS SHOULD DECREASE HERE MONDAY EVENING AS SURFACE PRESSURE
GRADIENTS RELAX.
THE LATEST MODELS SHOW A SHORTWAVE RIDGE IN THE MID AND UPPER LEVELS
MOVING IN ON TUESDAY. THE RISE IN HEIGHTS COMBINED WITH INCREASING
SOUTHWEST FLOW AHEAD OF ANOTHER AREA OF LOW PRESSURE NEAR THE COAST
OF BRITISH COLUMBIA SHOULD BE ENOUGH TO PUSH TEMPS BACK TO 5-8
DEGREES ABOVE NORMAL. AT THIS TIME TUESDAY LOOKS TO BE THE WARMEST
DAY OF NEXT WEEK. AS THIS LOW STARTS TO DIG SOUTH TUESDAY AFTERNOON
WINDS SHOULD PICK UP FROM THE SOUTHWEST ACROSS THE AREA WITH THE
HIGHEST WINDS ACROSS NORTHWEST SAN BERNARDINO COUNTY AND THE EASTERN
SLOPES OF THE SOUTHERN SIERRA NEVADA. GUSTS OVER 40 MPH ARE POSSIBLE
IN THESE AREAS THEN.
THE LOW NEAR BRITISH COLUMBIA IS FORECAST TO MOVE VERY SLOWLY SOUTH

WASHINGTON AND OREGON. AT THIS TIME ANY SIGNIFICANT MOISTURE IS
EXPECTED TO REMAIN WELL TO OUR NORTH AND ONLY A FEW HIGH CLOUDS LOOK
LIKELY FOR OUR AREA FROM TUESDAY NIGHT THROUGH NEXT THURSDAY NIGHT.
HOWEVER THE JET STREAM WILL SLOWLY SAG SOUTH WITH THE CORE OF THE
JET GETTING CLOSER TO THE AREA BY NEXT THURSDAY. WHILE IT IS A BIT
TOUGH TO GET TOO SPECIFIC THIS FAR OUT WITH WIND SPEEDS AS THE
ORIENTATION OF THE JET AND ALIGNMENT OF THE WIND FIELDS WITH HEIGHT
MAY VARY, PERIODS OF GUSTY WINDS LOOK A GIVEN IN THIS TIME FRAME AND
I HAVE ADJUSTED UP WINDS THROUGH THE PERIOD AS AT THE LEAST BREEZY
CONDITIONS OF 15-25 MPH CAN BE EXPECTED WITH HIGHER WINDS LIKELY ON
NEXT THURSDAY OR FRIDAY AS THE JET GETS CLOSER. TEMPS SHOULD ALSO
REMAIN ABOVE NORMAL BUT SHOW A TREND DOWN AS THE LOW GETS CLOSER AND
