AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE LAS VEGAS NV
255 AM PDT SAT MAY 7 2011

CORRECTION TO WORDING IN THE SYNOPSIS

.SYNOPSIS...A STRONG PACIFIC STORM WILL MOVE INTO THE AREA OVER THE
WEEKEND RESULTING IN LOCALLY BREEZY CONDITIONS TODAY AND THEN WINDY
TO VERY WINDY CONDITIONS ON MOTHERS DAY. A CHANCE OF SHOWERS AND
THUNDERSTORMS WILL ALSO BE SEEN...MAINLY ACROSS CENTRAL NEVADA ON
SUNDAY AND THEN ACROSS MUCH OF THE REGION ON MONDAY AS THE SYSTEM
SHIFTS EAST. TEMPERATURES WILL BE WELL ABOVE NORMAL TODAY AND THEN
DROP TO WELL BELOW NORMAL BY MONDAY.
&&

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...UPPER LOW OFF THE
SOUTHERN BRITISH COLUMBIA COAST WILL BE RESPONSIBLE FOR A MAJOR
CHANGE TO THE WEATHER ACROSS THE AREA OVER THE WEEKEND AND INTO THE
FIRST OF NEXT WEEK. LOW TO SHIFT ONTO THE PACIFIC NORTHWEST COAST
LATE TODAY AND THEN DIG SOUTH ACROSS NEVADA ON SUNDAY. ALTHOUGH A
CHANCE OF SHOWERS/ISOLATED THUNDERSTORMS WILL BE SEEN ACROSS CENTRAL
NEVADA ON SUNDAY THE MAIN CONCERN WITH THIS SYSTEM OVER THE WEEKEND
WILL BE WINDS. BREEZY CONDITIONS EXPECTED OVER THE ENTIRE AREA AHEAD
OF THIS SYSTEM TODAY WITH THE STRONGEST WINDS OVER THE NORTHWEST
PORTION OF SAN BERNARDINO COUNTY WHERE A WIND ADVISORY REMAIN IN
EFFECT. AS THE SYSTEM DROPS OVER THE AREA ON SUNDAY...WINDS WILL BE
ON THE INCREASE ACROSS THE ENTIRE CWA WITH THE MAIN FOCUS BEING OVER
THE MOJAVE DESERT. LOCAL HIRES MODELS INDICATE THAT DOWNSLOPE WINDS
ARE ALSO POSSIBLE ON THE EASTERN SLOPES OF THE SOUTHERN SIERRA AND
THE SPRING MOUNTAINS/WESTERN FOOTHILLS OF THE LAS VEGAS VALLEY FOR
MUCH OF SUNDAY AND WILL ISSUE A HIGH WIND WATCH WITH THIS PACKAGE.
WIND ADVISORIES WILL LIKELY BE NEEDED ELSEWHERE...ALONG WITH THE
CURRENT ADVISORY FOR NORTHWEST SAN BERNARDINO REMAINING IN EFFECT.
ON MONDAY THE LOW REMAINS OVER THE AREA...BUT DIGS A LITTLE FURTHER
SOUTH TO OVER THE CWA ON MONDAY WHICH WILL DECREASE FLOW ALOFT/
SURFACE GRADIENTS THUS DECREASING THE WINDS OVER THE AREA. HOWEVER
WITH THE LOW OVER THE AREA...ENOUGH INSTABILITY TO CONTINUE TO
PRODUCE SCATTERED SHOWERS ACROSS MAINLY THE NORTHERN PORTION OF THE
CWA. AS THE SYSTEM SHIFTS EAST MONDAY NIGHT...THE CHANCE OF SHOWERS
WILL BE ON THE DECREASE. THE NEXT CONCERN THEN TURNS TO
TEMPERATURES. WELL ABOVE NORMAL READINGS WILL CONTINUE TODAY...BUT
AS THE LOW SHIFTS INTO/OVER THE AREA...TEMPERATURES WILL BE ON THE
DECREASE WITH MOST DAYTIME READINGS DROPPING BETWEEN 20 AND 25
DEGREES BETWEEN TODAY AND MONDAY.

.LONG TERM...TUESDAY THROUGH FRIDAY...NOT MUCH TO CHANGE IN THIS
FORECAST CYCLE. MODELS CONTINUE WITH THEIR INDIVIDUAL PERSPECTIVES
ON THE DEPARTING STORM SYSTEM. THE GFS CONTINUES TO HAVE AN OPEN
WAVE DEPARTING THE AREA FASTER THAN THE ECMWF...WHICH STAYS WITH THE
SLOWER CLOSED LOW IDEA. LIKE PREVIOUS FORECAST PREFER THE FASTER GFS
IDEA AS THERE WILL BE A SHORTWAVE RIDGE MOVING IN...AND IT IS BEING
NUDGED BY THE NEXT STRONG TROUGH TO DROP SOUTH FROM THE GULF OF
ALASKA LATER IN THE WEEK.

LEFT PRECIPITATION FORECAST ALONE WHICH HAS RESIDUAL PRECIPITATION
IN OUR NORTHEAST ZONES CLOSEST TO THE TROUGH AXIS TUESDAY. THE
PRECIPITATION AND CLOUD COVER WILL DEPART QUICKLY ALONG WITH THE
TROUGH BY WEDNESDAY. WEDNESDAY THROUGH FRIDAY WILL SEE RIDGING OVER
THE AREA. TEMPERATURES SHOULD BE ABOVE AVERAGE ON THURSDAY AND
FRIDAY. ON FRIDAY THE RIDGE AXIS WILL HAVE SHIFTED EAST AS THE NEXT
TROUGH DROPS IN FROM THE NORTHERN PACIFIC. OTHERWISE THERE IS NO
SIGNIFICANT WEATHER OF NOTE THROUGH FRIDAY. LOOKING BEYOND THE
EXTENDED THE MODELS SHOW THE NEXT DEEP TROUGH DIGGING SOUTH AND A
LOW DEVELOPS OFF SHORE NEXT SATURDAY. HERE THE MODELS DIVERGE
SIGNIFICANTLY ON THE EVOLUTION OF THIS SYSTEM. FOR NOW ALL THAT CAN
BE SAID IS THAT THERE IS POTENTIAL FOR A MAJOR CHANGE IN THE AREAS
WEATHER LATE NEXT WEEKEND.
&&

.FIRE WEATHER...GUSTY SOUTHWEST WINDS EXPECTED THIS AFTERNOON AND
EVENING ACROSS MUCH OF MOHAVE COUNTY AND THIS ALONG WITH LOW
AFTERNOON HUMIDITIES WILL CREATE HAZARDOUS FIRE WEATHER CONDITIONS.
THUS WILL CONTINUE THE RED FLAG WARNING FOR ZONE 102 BELOW 3500
FEET. GUSTY WINDS WILL ALSO BE SEEN OVER CALIFORNIA ZONE 228 THIS
AFTERNOON WHICH WILL ALSO HAVE VERY LOW AFTERNOON HUMIDITIES.
HOWEVER CRITERIA OF 6 HOURS OR MORE IS MARGINAL ACROSS MUCH OF THE
ZONE SO OPTED NOT TO ISSUE ANY HIGHLIGHTS FOR THIS AREA. WILL NEED
TO MONITOR DURING THE DAY HOWEVER. WINDS WILL BE INCREASING ON
SUNDAY ACROSS MUCH OF THE DISTRICT...BUT TEMPERATURES WILL BE
LOWERING...ALLOWING MINIMUM HUMIDITIES TO INCREASE SLIGHTLY. THE
MAIN AREA OF CONCERN WILL CONTINUE TO BE MOHAVE COUNTY...BUT ALSO
FAR SOUTHERN NEVADA AND WILL CONTINUE THE RED FLAG WARNINGS IN THESE
AREAS FOR SUNDAY.
&&

.AVIATION...FOR MCCARRAN...SOUTH TO SOUTHWEST WINDS WILL PERSIST
THROUGH SUNDAY MORNING. THIS MORNING THE GUSTS IN THE 20-24 KNOTS
RANGE WILL SUBSIDE A FEW HOURS BEFORE THEY RESUME AGAIN LATE IN THE
MORNING. PEAK GUSTS THIS AFTERNOON WILL BE AROUND 30 KNOTS. WINDS
