AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE LAS VEGAS NV
315 AM PDT SAT SEP 15 2007

CORRECTION TO WATCH/WARNING/ADVISORY SECTION

.SYNOPSIS...A LOW PRESSURE SYSTEM NEAR THE NORTHERN CALIFORNIA
COAST WILL PRODUCE BREEZY TO WINDY CONDITIONS ACROSS THE SOUTHERN
GREAT BASIN AND MOHAVE DESERT THROUGH THE WEEKEND. MOISTURE WILL
INCREASE SOMEWHAT AS THE SYSTEM MOVES INLAND SUNDAY RESULTING IN A
CHANCE OF THUNDERSTORMS OVER NORTHWEST ARIZONA AND FAR EASTERN
PORTIONS OF SOUTHERN NEVADA. TEMPERATURES WILL COOL SEVERAL DEGREES
BEHIND THE SYSTEM ON MONDAY AS DRIER AIR MOVES BACK IN.
&&

.SHORT TERM...CLOSED LOW CENTERED OVER THE NORTHERN CALIFORNIA COAST
TO REMAIN IN PLACE THROUGH THE NEXT 24 HOURS. WATER VAPOR SHOWING
WEAK SHORT WAVE ROTATING AROUND LOW AND MOVING INTO THE SOUTHERN
SIERRA AS OF 09Z WITH MAIN RESULT BEING MAINLY LEE ENHANCED CLOUDS
ACROSS THE NORTHWEST PORTION OF THE CWA. MAIN CONCERN TODAY WILL BE
WINDS ACROSS MAINLY THE NORTHERN PORTION OF THE DISTRICT. JET MAX
APPEARS TO BE SIMILAR TO FRIDAY...ALTHOUGH BOTH NAM/GFS TRENDING
POSITION SLIGHTLY FURTHER NORTH. SURFACE GRADIENTS ALSO PROGGED TO
BE LESS THAN FRIDAY...ESPECIALLY WESTERN PORTION OF THE CWA. THUS IT
APPEARS THAT LESS WINDS WILL BE SEEN TODAY THAN ON FRIDAY...WITH THE
MAIN FOCUS BEING LINCOLN COUNTY. DO NOT BELIEVE OVERALL WIND SPEEDS
TO REACH ADVISORY LEVELS BUT WITH KEEP MENTION OF BREEZY/WINDY IN
THE ZONES. SEE FIRE WEATHER DISCUSSION BELOW FOR FIRE CONCERNS. ON
SUNDAY LOW TO OPEN INTO TROUGH AND DIG SOUTH...PUSHING OVER CWA BY
00Z MONDAY WITH TROUGH AXIS NORTHWEST NEVADA/SOUTHERN CALIFORNIA
COAST. BOTH NAM/GFS IN FAIR AGREEMENT WITH TIMING AND POSITION OF
AXIS. THIS TO AGAIN BRING BREEZY CONDITIONS ACROSS MUCH OF THE CWA.
BROAD TROUGH TO THEN REMAIN OVER THE AREA ON MONDAY AS AREA WAITS
POSSIBLE DEEP TROUGH INTO THE LONG TERM. AS UPPER LOW DIGS SOUTH ON
SUNDAY...MOISTURE TO BE PULLED NORTH TONIGHT/SUNDAY WITH MAIN AREA
BEING NORTHWEST ARIZONA...EXTREME SOUTHEAST CALIFORNIA AND EXTREME
SOUTHERN NEVADA. DECREASE STABILITY WITH POSSIBLE UPPER LEVEL
DYNAMICS ASSOCIATED WITH THE TROUGH TO BRING ISOLATED/SCATTERED
THUNDERSTORMS TO THIS AREA LATE TONIGHT AND INTO SUNDAY. AS TROUGH
PUSHES OVER THE AREA BY MONDAY...DRIER FLOW TO RETURN TO THE CWA
WITH CONVECTION LIMITED TO THE EXTREME EASTERN PORTION OF MOHAVE
COUNTY BY MONDAY AFTERNOON. IN ADDITION TO THE WINDS/CONVECTION...
NEXT CHANGE WILL BE COOLER TEMPERATURES. SOUTHWEST FLOW TO KEEP
TEMPS TODAY SIMILAR TO THOSE ON FRIDAY...HOWEVER WEST TO NORTHWEST
FLOW ALOFT ON MONDAY AS TROUGH PASSES TO DROP TEMPS GENERALLY 5-7
DEGREES...RESULTING IN SLIGHTLY BELOW NORMAL READINGS BY THE FIRST
OF NEXT WEEK.

.LONG TERM...UNSETTLED WEATHER CONDITIONS ARE ON THE WAY WITH MUCH
COOLER TEMPERATURES AND MAYBE AN INCREASING CHANCE FOR SHOWERS LATE
IN THE WEEK. MODELS FORECASTING AN AREA OF LOW PRESSURE FORMING OVER
THE PACIFIC NORTHWEST TUESDAY...SLIDING SOUTH ALONG THE COAST
WEDNESDAY AND THEN MOVING OVER THE AREA THURSDAY THROUGH AT LEAST
FRIDAY. STILL LOOKING AT SOME MODEL DIFFERENCES RELATED TO THE TRACK
OF THE LOW BUT MODELS ARE BEGINNING TO REACH A CONSENSUS ON THE
STRENGTH OF THE SYSTEM. CONFIDENCE IS NOW FAIRLY HIGH THAT AFTERNOON
TEMPERATURES WILL ONLY REACH INTO THE 80S AT MCCARRAN THURSDAY AND
FRIDAY WITH LOWS SLIPPING INTO AT LEAST THE UPPER 60S. ENSEMBLE MOS
GUIDANCE HAS A LARGE TEMPERATURE SPREAD BY FRIDAY WITH THE WARMEST
MEMBER FORECASTING 90 DEGREES AND THE COOLEST MEMBER 78 FOR KLAS.
WENT WITH THE MID 80S FOR NOW UNTIL MODELS BETTER DEFINE THE LOW
TRACK AND MOISTURE PROFILE. AT THIS TIME...MOISTURE LOOKS RATHER
LIMITED WITH THIS SYSTEM AND IS TIED MAINLY TO THE LOW ITSELF AS IT
MOVES OVER LAND. THEREFORE...LEFT THE POP GRIDS UNTOUCHED AS THEY
REFLECT THIS DRIER SOLUTION WELL. HOWEVER...ANY FURTHER JOG WEST IN
THE FORECASTED TRACK AS WAS INDICATED BY THE 18Z DGEX...AND THE LOW
WOULD TRACK OVER WATER INCREASING THE POTENTIAL FOR RAIN OVER THE
AREA.
&&

.AVIATION...FOR MCCARRAN...GUSTY SOUTHWEST WINDS ARE EXPECTED TO
INCREASE AGAIN BY MID MORNING TODAY AND AGAIN SUNDAY WITH SUSTAINED
WIND SPEEDS AROUND 15 KTS AND GUSTS TO 25 KTS. LIGHT TO MODERATE
MECHANICAL TURBULENCE IS POSSIBLE FROM SFC THROUGH 15K FEET ALONG
ALL APPROACH CORRIDORS DURING THIS TIME. THERE IS ALSO A CHANCE FOR
THUNDERSTORMS ALONG THE MORMON MESA AND PEACH SPRINGS CORRIDORS
SUNDAY AFTERNOON AND INTO THE EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...FOR THE REST OF TONIGHT THROUGH SUNDAY EXPECT A CYCLE
OF STRONG SOUTHWESTERLY WINDS GUSTING FROM 25-35 KTS DURING THE
AFTERNOON...AND DECREASING DURING THE NIGHT. SFC BASED MECHANICAL
TURBULENCE SHOULD BE EXPECTED AT ALL LOCATIONS...ALONG WITH POSSIBLE
MTN WAVE TURB LEE OF RANGES.
&&

.FIRE WEATHER...LOW PRESSURE SYSTEM OFF THE NORTHERN CALIFORNIA
COAST WILL ONCE AGAIN ALLOW INCREASED AFTERNOON WINDS ACROSS THE
DISTRICT TODAY. THE STRONGEST WINDS WILL BE ACROSS LINCOLN COUNTY
WITH GUSTS TO OVER 35 MPH...THUS THE FIRE WEATHER WATCH HAS BEEN
UPGRADED TO A RED FLAG WARNING FOR THIS AREA. ALTHOUGH LOCAL GUSTY
WINDS WILL OCCUR ACROSS ESMERALDA AND CENTRAL/SOUTHERN NYE COUNTIES
TODAY WIDESPREAD WINDS MEETING RED FLAG CONDITIONS ARE NOT EXPECTED
AND HAVE DROPPED THE FIRE WEATHER WATCH FOR TODAY. ANOTHER AREA OF
CONCERN WILL BE THE NORTHERN PORTION OF MOHAVE COUNTY. ONCE AGAIN
LOCAL WIND SPEEDS MAY REACH RED FLAG CRITERIA...HOWEVER MINIMUM
RELATIVE HUMIDITY VALUES ARE EXPECTED TO GENERALLY REMAIN ABOVE THE
15 PERCENT REQUIREMENT. SIMILAR TO CENTRAL NEVADA ZONES HOWEVER...
ISOLATED RED FLAG CONDITIONS WILL BE NOTED AND THE OVERALL SITUATION
WILL BE MONITORED DURING THE DAY.
