AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
900 PM PDT THU JUL 3 2008

.SYNOPSIS...A WEAK LOW PRESSURE SYSTEM WILL MOVE ACROSS NORTHERN
NEVADA ON FRIDAY...RESULTING IN LOCALLY BREEZY CONDITIONS ACROSS THE
AREA. MEANWHILE CONTINUED HOT AND DRY CONDITIONS ARE EXPECTED OVER
THE SOUTHERN GREAT BASIN AND MOJAVE DESERT THROUGH THE HOLIDAY
WEEKEND.
&&

.UPDATE...EXCESSIVE HEAT WARNING WAS CANCELLED EARLIER AS AFTERNOON
HIGHS DID NOT QUITE REACH CRITERIA. OVERALL SHORT TERM FORECAST
REMAINS ON TRACK AS WEAK SHORT WAVE MOVES ACROSS NORTHERN NEVADA ON
FRIDAY...RESULTING IN BREEZY CONDITIONS ACROSS MUCH OF THE CWA.
HOWEVER RIDGE STILL REMAINS THE KEY FACTOR FOR THE SHORT TERM...THUS
ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS TO CONTINUE THROUGH THE
HOLIDAY WEEKEND. NO UPDATES PLANNED ATTM.
&&

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS GENERALLY LESS THAN 8KTS
THROUGH 18Z FRIDAY BEFORE INCREASING TO BETWEEN 10-20KTS WITH LOCAL
GUSTS TO AROUND 30KTS AFTER 18Z. HIGH LEVEL SMOKE LAYERS TO CONTINUE
ACROSS THE AREA. ISOLATED LATE AFTERNOON AND EVENING THUNDERSTORMS
ARE POSSIBLE IN THE PEACH SPRINGS CORRIDOR OVER THE HOLIDAY WEEKEND
WITH NO WEATHER IMPACTS EXPECTED ACROSS SOUTHERN NEVADA AND MOST OF
SOUTHEAST CALIFORNIA.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SMOKE LAYERS ALOFT WITH VISIBILITY POTENTIALLY LOWERING
TO MVFR LEVELS IN VICINITY OF THE EASTERN SIERRA SLOPES THROUGH THE
HOLIDAY WEEKEND. OTHERWISE GENERALLY DIURNAL WINDS THROUGH 18Z
FRIDAY WITH SOUTHWEST WINDS THEN INCREASING TO BETWEEN 10-20KTS WITH
GUSTS 30-35KTS AFTER 18Z. ISOLATED LATE AFTERNOON/EVENING
THUNDERSTORMS EXPECTED MAINLY EAST OF MOHAVE COUNTY ARIZONA THROUGH
THE WEEKEND.
&&

.PREV DISCUSSION...345 PM PDT SHORT TERM...LITTLE CHANGE WAS NEEDED
TO THE EXISTING FORECAST PACKAGE...WITH MODELS SHOWING RELATIVELY
GOOD CONTINUITY. A TROUGH OF LOW PRESSURE WILL PASS ACROSS THE PAC
NW ON FRIDAY...WHICH WILL LOWER HEIGHTS AND ULTIMATELY TEMPERATURES
A COUPLE OF DEGREES AT MOST LOCATIONS. WINDS ALOFT WILL ALSO
INCREASE OUT OF THE SOUTHWEST...SO BREEZY CONDITIONS ARE EXPECTED
AREAWIDE DURING THE AFTERNOON AFTER MIXING...ESPECIALLY ACROSS THE
NORTHERN HALF OF THE CWA...SO HAVE ISSUED A RED FLAG WARNING FOR
FRIDAY. SEE RNORFWVEF FOR DETAILS. MOST OF THE MOISTURE ASSOCIATED
WITH THIS MORNINGS MINIMAL GULF SURGE HAS MIXED OUT...SO WITH NO NEW
MOISTURE ADVECTION EXPECTED...HAVE TAKEN OUT ANY MENTION OF TSTMS
FOR FRIDAY AND SATURDAY. CURRENT WATER VAPOR IMAGERY STILL SHOWS A
GOOD PLUME OF MID LEVEL MOISTURE ORIGINATING FROM TS BORIS GETTING
PICKED UP IN THE SOUTHWEST FLOW...BUT SUBSIDENCE ASSOCIATED WITH THE
STRONG HIGH PRESSURE OVERHEAD SEEMS TO BE HAMPERING ANY DEVELOPMENT.

.LONG TERM...STILL THE SAME OLD SONG AND DANCE WITH THE EXTENDED.
THE MAIN WEATHER CONCERNS WILL BE THE HEAT...SMOKE AND THUNDERSTORM
POTENTIAL. THE ECMWF IS STILL TRYING THE HARDEST TO BRING UP
MOISTURE INTO THE SOUTHERN PORTIONS OF THE CWFA...WHILE THE
OPERATIONAL GFS REMAINS MUCH DRIER. AN UPPER RIDGE OFF THE COAST OF
CALIFORNIA ON SUNDAY WILL SLOWLY BUILD INTO NEVADA BY TUESDAY.
RISING HEIGHTS AND WARMING ALOFT /H7 TEMPS GO FROM +16C TO +18C
SUNDAY TO +18C TO +20C TUESDAY ACROSS THE AREA/ WILL RESULT IN A
SLOW TREND UPWARDS IN TEMPERATURES. MODELS HAVE REMAINED CONSISTENT
IN ADVERTISING A STRONG RIDGE FOR SEVERAL RUNS...SO HAVE GONE AHEAD
AND ADJUSTED UP TEMPS A LITTLE MAINLY FOR MONDAY BUT MORE SO ON
TUESDAY. THIS WILL PUT MUCH OF THE AREA IN EXCESSIVE HEAT WARNING
LEVEL CONDITIONS...AND ALSO PUSH HIGH TEMPS TO NEAR RECORD OR RECORD
BREAKING LEVELS...SEE THE CLIMATE SECTION BELOW FOR DETAILS. FURTHER
WARMING WILL TAKE PLACE ON WEDNESDAY AS THE RIDGE ALOFT BECOMES
CENTERED OVER THE GREAT BASIN. HIGHS WILL BEGIN TO LOWER A LITTLE
THURSDAY AS THE RIDGE SLOWLY MOVES ON EASTWARD. THE ECMWF CONTINUES
TO KEEP BRINGING UP MOISTURE FROM THE SOUTHEAST INTO MOHAVE COUNTY
THROUGH NEXT WEEK...HOWEVER THE MID LEVEL FLOW REALLY DOES NOT LOOK
ALL THAT IMPRESSIVE WITH NO REAL GOOD SOUTH TO SOUTHEAST FLOW SEEN
ALIGNED AT THESE LEVELS. WILL KEEP IN A SLIGHT CHANCE OF
THUNDERSTORMS IN MOHAVE COUNTY FOR THIS TIME FRAME...BUT
UNCERTAINTIES CONTINUE. HOWEVER IF WE DO GET ENOUGH MOISTURE IN
PLACE...THE ENHANCED CLOUD COVER OR JUST THAT THE ATMOSPHERE WILL
HAVE MORE MOISTURE IN IT COULD CERTAINLY AFFECT TEMPS...THUS WHY WE
ARE STILL NOT GOING AS HOT AS SOME GUIDANCE. FLOW ALOFT WILL STILL
PUSH SMOKE INTO THE NORTHWEST PART OF THE CWFA FROM THE CALIFORNIA
FIRES...BUT BY MID-WEEK AS THE FLOW ALOFT WEAKENS IN RESPONSE TO THE
RIDGE BUILDING IN...THIS WILL MAKE THE TRAJECTORY OF ANY SMOKE
LAYERS MORE VARIABLE IN NATURE.
&&

.FIRE WEATHER...A TROUGH PASSING ACROSS THE PACIFIC NORTHWEST WILL
HELP INCREASE SOUTHWEST WINDS UP TO RED FLAG CRITERIA ACROSS NEVADA
ZONES 461...462...AND 465 ON FRIDAY...WITH BREEZY CONDITIONS
PERSISTING ELSEWHERE. BY SATURDAY...WINDS WILL HAVE DECREASED TO
BELOW CRITERIA...BUT WILL REMAIN BREEZY DURING THE AFTERNOON. STILL
NO END IN SIGHT TO HOT AND DRY CONDITION THROUGH THE BEGINNING OF
NEXT WEEK...HOWEVER...THERE IS AN OUTSIDE CHANCE THAT SOME MOISTURE
MAY WORK ITS WAY INTO MOHAVE COUNTY DURING THE MIDDLE PART OF NEXT
WEEK TO POSSIBLY ALLOW FOR ISOLATED THUNDERSTORMS TO DEVELOP IN THE
AFTERNOON AND EVENING HOURS WITH THE MAIN THREAT FROM ANY ACTIVITY
BEING DRY LIGHTNING.
&&

.CLIMATE...NEAR RECORD TO RECORD HIGH TEMPERATURES ARE POSSIBLE IN
PARTS OF THE AREA ON TUESDAY AND AGAIN ON WEDNESDAY. LAS VEGAS MAY
ALSO HAVE A GOOD CHANCE TO TIE THE RECORD HIGH MINIMUM TEMPERATURE
FOR WEDNESDAY THE 9TH OF 86 SET IN 1996.
