AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
920 AM PDT WED MAY 15 2013

.SYNOPSIS...COOLER TEMPERATURES WITH LOCALLY BREEZY TO WINDY
AFTERNOONS EXPECTED THROUGH FRIDAY AS A WEAK STORM LEAVES THE AREA

INTO EARLY SATURDAY. A CHANCE OF SHOWERS WILL BE SEEN WITH THIS
SECOND SYSTEM MAINLY ACROSS THE NORTHERN MOUNTAINS. TEMPERATURES
WILL BEGIN TO REBOUND THIS WEEKEND AND INTO EARLY NEXT WEEK.
&&

.UPDATE...THE UPPER LEVEL LOW WAS CENTERED ALONG THE NV-UT BORDER AT
16Z THIS MORNING AND WINDS HAVE CALMED ACROSS THE AREA. A FEW HIGH
CLOUDS HAVE BEEN NOTED ACROSS THE AREA AND SKY GRIDS WERE UPDATED
BASED ON THE LATEST TRENDS AND GUIDANCE. OTHERWISE...THE CURRENT
FORECAST IS ON TRACK AND NO FURTHER UPDATES PLANNED THIS MORNING.
WILL BE TAKING A CLOSE LOOK AT THE NEW 12Z GUIDANCE TO DETERMINE
WHETHER ADDITIONAL FIRE/WIND HIGHLIGHTS ARE NEEDED THURSDAY.
&&

.AVIATION...FOR MCCARRAN...WINDS SHOULD PICK UP OUT OF THE
SOUTH-SOUTHWEST AROUND 20Z TODAY WITH SUSTAINED WINDS INCREASING TO
10-14 KTS WITH GUST OF 18-22 KTS. SPEEDS MAY DECREASE SLIGHTLY AFTER
12Z THURSDAY. FEW-SCT CLOUDS AOA 25K FEET AT TIMES.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ACROSS THE MOJAVE DESERT...EXPECT SOUTHWEST WINDS OF
10-20 KTS WITH GUSTS OF 15-30 KTS ESPECIALLY AFTER 20Z TODAY. WINDS
SHOULD DECREASE SLIGHTLY TONIGHT BUT STILL REMAIN GUSTY. ACROSS
ESMERALDA COUNTY AND WESTERN PORTIONS OF INYO COUNTY EXPECT WEST TO

.PREV DISCUSSION...
ISSUED 320 AM PDT WED MAY 15 2013

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...CENTER OF A LOW
CIRCULATION WHICH MOVED INTO THE REGION ON TUESDAY IS JUST ABOUT
CENTERED OVER SOUTHERN NEVADA AS OF 09Z THIS MORNING. ALTHOUGH
LIMITED CLOUDS ASSOCIATED WITH THIS SYSTEM...LOCAL GUSTY WINDS STILL
BEING REPORTED. BY 18Z THIS MORNING...THE UPPER LOW SHOULD BE EAST
OF THE REGION...RESULTING IN LESS WIND AND MOSTLY CLEAR SKIES TODAY
WITH GENERALLY DRY SOUTHWEST FLOW ALOFT OVER THE CWA. THE NEXT
PACIFIC TROUGH WILL BEGIN TO DROP SOUTH ALONG THE WEST COAST ON
THURSDAY HOWEVER WITH INCREASED WINDS EXPECTED ACROSS MUCH OF THE
CWA THURSDAY AFTERNOON. POSSIBLE DOWNSLOPE CONDITIONS MAY FORM OVER
THE LEE SIDE OF THE SOUTHERN SIERRA LATE THURSDAY/THURSDAY EVENING.
HOWEVER BOTH THE DOWNSLOPE CONDITIONS AND THE GRADIENT WINDS ON
THURSDAY APPEAR TO BE BELOW ADVISORY LEVELS WITH GUSTS GENERALLY IN
THE 35 TO 40 MPH RANGE. THIS MAY CREATE FIRE WEATHER CONCERNS
HOWEVER. DIFFERENCE OCCUR IN THE SHORT RANGE MODELS ON THE TIMING
AND INTENSITY OF THIS TROUGH FOR THURSDAY NIGHT/FRIDAY WITH THE
GFS/NAM BEING A BIT DEEPER AND SLOWER WITH THE EASTWARD TRANSITION
ACROSS THE CWA THAN THE ECMWF. FOR NOW HAVE TRIED TO BLEND THE
TIMING...RESULTING IN MOVING THE TROUGH ACROSS THE CWA ON FRIDAY
BEFORE EXITING THE REGION BY 12Z SATURDAY. THIS WILL BRING A CHANCE
OF SHOWERS TO THE SOUTHERN SIERRA BY LATE THURSDAY WITH A CHANCE OF
SHOWERS THEN REMAINING MAINLY OVER THE NORTHERN MOUNTAINS ON FRIDAY
BEFORE DRYING IS SEEN FROM THE WEST FRIDAY NIGHT. WITH THE PASSAGE
OF THE TROUGH TODAY AND THEN AGAIN ON FRIDAY...TEMPERATURES WILL BE
COOLING FROM THE NEAR RECORD READINGS OF THE PAST TWO
DAYS...RESULTING IN TEMPERATURES ON FRIDAY BEING NEAR NORMAL.

.LONG TERM...SATURDAY THROUGH TUESDAY...RIDGING OFF THE SOUTHERN
CALIFORNIA COAST WILL SLOWLY TRANSITION EAST OVER THE COURSE OF THE
WEEKEND WHICH WILL KEEP THE FORECAST AREA UNDER DRY NORTHWESTERLY
FLOW AND RESULT IN TEMPERATURES CLIMBING BACK TO APPROXIMATELY 5
DEGREES ABOVE NORMAL BY SUNDAY AFTERNOON. A SLIGHT DECREASE IN
TEMPERATURES ARE EXPECTED MONDAY AS THE LONGWAVE TROUGH TO THE EAST
BROADENS AND DEEPENS WITH THE JET CORE JUST BEYOND THE UPSTREAM
INFLECTION POINT...BUT NO CHANGES OTHERWISE.

BY TUESDAY A DEEP LOW PRESSURE SYSTEM CENTERED JUST OFF VANCOUVER
ISLAND WILL BEGIN TO HAVE AN IMPACT...WITH SOUTHWESTERLY FLOW
INCREASING ACROSS THE REGION BY THE AFTERNOON. BASED ON LATEST
GUIDANCE...THIS SYSTEM WILL SLOWLY MOVE SOUTH THE REMAINDER OF THE
WEEK WITH THE CENTER OF THE MID LEVEL LOW EXPECTED OVER THE NORTHERN
CALIFORNIA COAST BY THE END OF THE WEEK. THIS WOULD RESULT IN
INCREASED SOUTHWESTERLY SURFACE WINDS THROUGH FRIDAY.
&&

.FIRE WEATHER...A COOLING TREND WILL BEGIN TODAY AS A WEAK STORM
EXITS THE REGION. HOWEVER ANOTHER...STRONGER STORM WILL BEGIN TO
MOVE INTO THE AREA LATE THURSDAY BEFORE CROSSING OVER THE DISTRICT
ON FRIDAY. INCREASED SOUTHWEST WINDS WILL BE SEEN AHEAD OF THIS
STORM THURSDAY AFTERNOON WITH MANY AREAS SEEING GUSTS TO OVER 30
MPH. THE STRONGEST WINDS AT THIS TIME APPEAR TO BE OVER MOHAVE
COUNTY...AZ102...WITH GUSTS OF 35 TO 40 MPH AND THIS COMBINED WITH
THE DRY FUELS/LOW AFTERNOON RELATIVE HUMIDITY WILL PROMPT THE
ISSUANCE OF A FIRE WEATHER WATCH FOR THIS AREA FOR THURSDAY. THERE
IS STILL SOME UNCERTAINTY ON THE INTENSITY OF THIS STORM WITH WINDS
POSSIBLY BEING STRONGER THAN CURRENTLY EXPECTED ACROSS THE MOJAVE
DESERT AND SOUTHERN NEVADA. THE FIRE WEATHER WATCH MAY NEED TO BE
EXPANDED INTO THESE AREAS AND/OR A RED FLAG WARNING ISSUED IN THE
AFTERNOON PACKAGE.
