AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1010 AM PDT THU JUL 3 2008

.SYNOPSIS...HIGH PRESSURE AND HOT CONDITIONS WILL CONTINUE TODAY.
AN EXCESSIVE HEAT WARNING WILL BE IN EFFECT TODAY FOR THE LOWER
DESERT AREAS. A WEAK UPPER LEVEL DISTURBANCE WILL MOVE THROUGH
THE FORECAST AREA ON FRIDAY DROPPING TEMPERATURES A COUPLE OF
DEGREES. HOT TEMPERATURES WILL CONTINUE THOUGH THE MIDDLE OF NEXT
WEEK WITH AFTERNOON HIGHS POSSIBLE APPROACHING HEAT ADVISORY
CONDITIONS ONCE AGAIN.
&&

.UPDATE...CURRENT FORECAST RIGHT ON TRACK SO NO MAJOR UPDATES WILL
BE NEEDED THIS MORNING. THE 12Z KDRA SOUNDING INDICATES ABOUT 2
DEGREES OF WARMING FROM JUST ABOVE THE SURFACE TO OVER 700MB...SO
EXCESSIVE HEAT WARNING STILL LOOKS GOOD. WATER VAPOR IMAGERY SHOWS
A PLUME OF MOISTURE FROM TROPICAL STORM BORIS GETTING CAUGHT UP IN
THE SOUTHWESTERLY FLOW. ALSO...OUTFLOWS FROM TSTMS ACROSS NORTHERN
MEXICO LAST NIGHT HAVE MOISTENED UP THE GULF OF CA...AND THE VWP
FROM YUMA INDICATES A SHALLOW /4KFT / PUSH OF MOIST AIR UP FROM THE
SOUTH...BUT WITH THE STRONG HIGH OVERHEAD...WE ARE JUST TOO STABLE
FOR ANY CONVECTION...WARRANTS A CLOSE WATCH THOUGH.

&&
.AVIATION...FOR MCCARRAN...LIGHT AND VARIABLE WINDS WILL BECOME
SOUTHWESTERLY AT 7-12 KTS WITH GUSTS OF 15-20 KTS THIS AFTERNOON AND
EVENING. WINDS LOOK TO THEN LESSEN AROUND 2Z FRI...THEN BECOME
VARIABLE BETWEEN 12Z AND 15Z FRI. HIGH LEVEL SMOKE LAYERS AT/ABOVE
25K FEET ARE EXPECTED THROUGH THE NEXT 24 HOURS. A FEW CLOUDS
AT/ABOVE 16K FEET POSSIBLE THIS AFTERNOON/EVENING AND FEW-SCT CLOUDS
AT/ABOVE 16K FEET TOMORROW AFTERNOON/EVENING IN THE LAS VEGAS
VALLEY. ISOLATED LATE AFTERNOON AND EVENING THUNDERSTORMS ARE
POSSIBLE IN THE PEACH SPRINGS CORRIDOR OVER THE WEEKEND.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THE MAIN CONCERN WILL BE SMOKE LAYERS ALOFT WITH
VISIBILITY POTENTIALLY LOWERING TO MVFR LEVELS IN AREAS OF THE
EASTERN SLOPES OF THE SOUTHERN SIERRA AND IN THE OWENS VALLEY.
OTHERWISE LIGHT WINDS BECOMING SOUTHWEST AT 10-20 KTS THIS
AFTERNOON/EVENING...THEN BETWEEN 6Z AND 12Z...DIURNAL WINDS SHOULD
DEVELOP. FEW-SCT CLOUDS THIS AFTERNOON/EVENING ACROSS MOHAVE COUNTY
AND THE SAN BERNARDINO COUNTY DESERTS. AN INCREASE IN MOISTURE OVER
THE WEEKEND MAY ALLOW FOR ISOLATED TSTMS TO DEVELOP IN THE
AFTERNOON/EVENING ACROSS THE HIGHER ELEVATIONS OF MOHAVE COUNTY.

&&
.PREV DISCUSSION...SHORT TERM...TODAY THROUGH SATURDAY NIGHT.

AFTERNOON HIGH TEMPERATURES TODAY CONTINUE TO BE A CHALLENGE. AM
KIND OF SURPRISED THE OFFICIAL HIGH FOR WEDNESDAY WAS ONLY 109
DEGREES. BASED ON THICKNESS SCHEMES AND 850 TEMPERATURES...AFTERNOON
HIGHS TODAY SHOULD BE AROUND 111 DEGREES...JUST BELOW HEAT
ADVISORY CRITERIA. THE MAV CONTINUES TO BE THE WARMEST GUIDANCE
WITH 113 /00Z RUN/ AND 112 /06Z RUN/. WILL GO WITH 112 ALTHOUGH IT
MIGHT NOT GET THAT HOT OFFICIALLY. REALLY DON/T WANT TO YANK DOWN
THE EXCESSIVE HEAT WARNING SINCE IT IS ALREADY OUT AND WELL
ADVERTISED. BESIDES THERE WILL BE PLENTY OF PLACES ACROSS LAS
VEGAS VALLEY THAT HAVE READINGS ABOVE 112 DEGREES...MAYBE JUST NOT
THE OFFICIAL OBSERVING SITE.

A WEAK UPPER LEVEL SHORT WAVE WILL MOVE THROUGH ON FRIDAY
DROPPING TEMPERATURES A DEGREE OR SO. THERE IS ALSO THE POTENTIAL
FOR SOME GUSTY WINDS DURING THE AFTERNOON HOURS. THE WINDS WILL BE
MORE OF A FIRE WEATHER CONCERN AND MAINLY CONFINED TO THE UPPER
ELEVATIONS AND NORTHERN LINCOLN COUNTY.

THE MODELS STILL DIFFER ON HOW MUCH MOISTURE WILL RETURN TO THE
AREA ON SATURDAY. THE HIGH REALLY FLATTENS OUT AND THE NAM AND GFS
SUPPRESS THE POPS FOR MOHAVE COUNTY. THE EUROPEAN STILL BRINGS A
SLUG OF MOISTURE INTO THE AREA. NOT EXACTLY SURE WHERE THE
MOISTURE COMES FROM UNLESS IT IS TRYING TO TAP INTO MOISTURE FROM
T.S. DOUGLAS. AT THIS TIME THE STORM SHOULD NOT REALLY HAVE AN
AFFECT ON OUR SENSIBLE WEATHER. WILL KEEP SOME LOW END SLIGHT
CHANCE POPS FOR MOHAVE COUNTY ON SATURDAY. DRY LIGHTNING MIGHT BE
MORE OF A CONCERN.

.LONG TERM...A WEAK SHORTWAVE PASSES NORTH OF THE AREA SUNDAY
FLATTENING THE UPPER RIDGE AND KEEPING TEMPERATURES SUPPRESSED
SOMEWHAT. BEGINNING MONDAY AND CONTINUING THROUGH THE WEEK...HIGH
PRESSURE RE-ASSERTS ITSELF OVER THE SOUTHWEST AND HIGHER TEMPS
RETURN. LATEST MOS GUIDANCE PUSHES HIGH TEMPERATURES IN LAS VEGAS TO
114/113 TUESDAY/WEDNESDAY AND RAW GFS DATA GIVES 116/117. THIS WOULD
NOT ONLY EXCEED HEAT ADVISORY CRITERIA BUT BREAK RECORDS FOR THOSE
DATES. WHILE THIS MAY BE A TREND IN THE RIGHT DIRECTION...THE
OFFICIAL FORECASTED HIGH WILL REMAIN 111 BOTH DAYS FOR THIS PACKAGE.

AS FOR MOISTURE...MAINLY DRY CONDITIONS EXPECTED OVER THE AREA WITH
THE EXCEPTION OF MOHAVE COUNTY WHERE ISOLATED THUNDER IS POSSIBLE
EACH AFTERNOON/EVENING. THE ECMWF TRIES TO SUGGEST DEEPER MOISTURE
APPROACHING THE AREA LATE IN THE WEEK. THIS APPEARS TO BE TIED TO AN
INVERTED TROUGH OR LOW MOVING FROM SOUTHEAST TO NORTHWEST ACROSS
MEXICO AT THE BASE OF THE RIDGE. HOWEVER...THE MOISTURE REMAINS WELL
SOUTH OF THE AREA BY THE END OF DAY 7 SO WILL JUST KEEP AN EYE ON IT
FOR NOW.
&&

.FIRE WEATHER...AS THE WEAK SHORT WAVE TROFF MOVES THROUGH ON
FRIDAY GUSTY WINDS COULD OCCUR. THE MAIN AREAS OF CONCERN WOULD BE
THE HIGHER ELEVATIONS AND NORTHERN LINCOLN COUNTY /FIRE ZONE 461/.
THE RH VALUES WILL CONTINUE TO BE LOW AND WINDS COULD GUST TO 35
MPH IN AFTERNOON AND EVENING HOURS FOR THREE TO SIX HOURS. NOT ALL
THAT CONFIDENT JUST YET SO WILL HOLD OFF ON A WATCH. THE OTHER
CONCERN COULD BE DRY LIGHTNING FOR MOHAVE COUNTY ON SATURDAY AS
INSTABILITY DECREASES WITH LI/S AND SHOWALTER GOING NEGATIVE AND
0-1KM CAPE AROUND 100-500 J/KG.
