AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
346 AM PDT SAT JUN 16 2012

.SYNOPSIS...THERE IS A SLIGHT CHANCE OF AFTERNOON AND EVENING
THUNDERSTORMS OVER THE SOUTHERN SIERRA AND THE MOUNTAINS OF SOUTH
CENTRAL NEVADA TODAY. VERY DRY AND WINDY WEATHER CAN BE EXPECTED ON
MONDAY. TEMPERATURES WILL BE SEVERAL DEGREES ABOVE NORMAL...WITH THE
HOTTEST WEATHER EXPECTED DURING THE SECOND HALF OF THE WEEK.
&&

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...CLEAR SKIES THIS MORNING
AS WATER VAPOR SHOWS AN UPPER LOW OFF THE SOCAL COAST. LOW PROGGED TO
RETROGRADE FURTHER OUT OVER THE EASTERN PACIFIC TODAY AND SUNDAY AS
HIGH PRESSURE OVER THE NORTHEAST PACIFIC AND THE FOUR CORNERS
REGIONS ATTEMPTS TO MERGE OVER THE SOUTHWEST STATES. SOME
CONVERGENCE ALONG A STATIONARY BOUNDARY ACROSS SOUTH CENTRAL NEVADA
MAY PROVIDE JUST ENOUGH LIFT FOR A SLIGHT CHANCE OF THUNDERSTORMS
TODAY. THE SETUP DOES NOT LOOK AS GOOD AS FRIDAY THOUGH. DRY AND
WARMER ON SUNDAY UNDER THE EXPANDING RIDGE. ON MONDAY...MODELS IN
AGREEMENT MOVING A TROUGH ACROSS THE NORTHWEST STATES WITH THE
JETSTREAM SAGGING AS FAR SOUTH AS THE NORTHERN NEVADA BORDER. MAIN
IMPACT FOR THE AREA WILL THE WIND. SURFACE TROUGH PROGGED TO LIE
ACROSS THE GREAT BASIN WITH STRONGEST BELT OF WINDS EXPECTED ACROSS
THE MOJAVE DESERT...ESPECIALLY SAN BERNARDINO COUNTY. STILL HAVE
TIME TO CONSIDER OUR OPTIONS FOR ANY WIND PRODUCTS SO WILL LET
DAYSHIFT TAKE ANOTHER LOOK AT THE SITUATION. TEMPERATURES WILL BE
ABOVE NORMAL THROUGH MONDAY.

.LONG TERM...TUESDAY THROUGH SATURDAY...GENERALLY WEAK NORTHWEST
FLOW ALOFT OVER THE AREA ON TUESDAY TO TRANSITION TO A LIGHT
SOUTHWEST FLOW BY THURSDAY AS A RIDGE BUILDS OVER THE FOUR CORNERS
AREA WITH A WEAK CUT-OFF LOW WELL OFF THE SOUTHERN CALIFORNIA COAST.
THE CUT-OFF LOW IS THEN MERGED/CAUGHT IN A BROAD PACIFIC SHORT WAVE
MOVING INTO THE PACIFIC NORTHWEST BY SATURDAY...RESULTING IN
INCREASED SOUTHWEST FLOW ACROSS THE AREA BY SATURDAY AFTERNOON WITH
THE RIDGE BEING PUSHED FURTHER EAST. ALTHOUGH THIS PATTERN MAY OPEN
THE DOOR FOR A BRIEF MOISTURE PUSH LATE NEXT WEEK...FOR NOW WILL
MAINTAIN THE DRY FORECAST THAT THE NORTHWEST TO WEAK SOUTHWEST FLOW
WOULD PRODUCE. THE WINDS THAT ARE EXPECTED ON MONDAY WILL CONTINUE
BREEZY TO WINDY CONDITIONS ACROSS PORTIONS OF THE CWA ON
TUESDAY...BUT OVERALL ONLY LOCALLY BREEZY CONDITIONS EXPECTED FOR
THE REMAINDER OF THE LONG TERM.

THE MAIN CONCERN FOR THE LONG TERM WILL CONTINUE TO BE TEMPERATURES.
ALTHOUGH THE GFS/ECMWF ARE IN EXCELLENT AGREEMENT ON THE SYNOPTIC
DETAILS THERE IS A CONSIDERABLE DIFFERENCE IN MOS GUIDANCE WITH THE
GFS RUNNING MUCH COOLER ESPECIALLY IN THE WEDNESDAY THROUGH FRIDAY
TIMEFRAME. CURRENT FORECAST IS SHOWING WARMING DURING NEXT WEEK
WHICH LOOKS GOOD AS THE SOUTHWEST FLOW INCREASES OVER THE AREA BUT
DUE TO THE UNCERTAINTY AND BROAD RANGE...HAVE ONLY TWEAKED THE
NUMBERS A BIT FROM THE PREVIOUS PACKAGE.
&&

.AVIATION...FOR MCCARRAN...NO SIGNIFICANT WEATHER IS EXPECTED
TODAY. WINDS ARE EXPECTED TO BE 8 KTS OR LESS WITH SOUTHWEST
WINDS THROUGH 19Z THEN BECOMING SOUTHEAST...BEFORE BECOMING
SOUTHWEST AGAIN BY 04Z SUNDAY. TEMPERATURES ARE EXPECTED TO BE ABOVE
100 DEGREES BETWEEN 20Z THROUGH 03Z SUNDAY.

FOR THE REST OF SOUTHERN NEVADA...LIGHT WINDS FOLLOWING TYPICAL
DIURNAL DIRECTIONS CAN BE EXPECTED THROUGH TODAY. ISOLATED
THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE OVER THE SOUTHERN SIERRA
AND THE CENTRAL NEVADA MOUNTAINS THIS AFTERNOON. ALTHOUGH MOSTLY
CLEAR SKIES ARE EXPECTED...SCT-BKN CLOUDS AOA 120K FEET NEAR
AFTERNOON CONVECTION.
&&

.FIRE WEATHER...VERY DRY CONDITIONS WILL CONTINUE OVER THE REGION
THROUGH NEXT WEEK. THERE IS A SLIGHT CHANCE OF THUNDERSTORMS OVER
THE SOUTHERN SIERRA AND THE MOUNTAINS OF ESMERALDA...CENTRAL
NYE...AND NORTHERN LINCOLN COUNTIES TODAY. ANY STORMS THAT DO
DEVELOP WILL RESULT IN LITTLE RAINFALL...BUT THE EXPECTED COVERAGE
IS LESS THAN 15 PERCENT...SO WILL NOT ISSUE A RED FLAG WARNING FOR
DRY LIGHTNING. ANY SHOWER OR THUNDERSTORM COULD ALSO PRODUCE WIND
GUSTS OF 50 MPH. SOUTH TO SOUTHWEST WINDS WILL INCREASE ON SUNDAY
AFTERNOON...BUT SHOULD REMAIN AT OR BELOW 35 MPH AND BELOW RED FLAG
THRESHOLDS. ON MONDAY...WINDS WILL INCREASE FURTHER WITH GUSTS ABOVE
35 MPH POSSIBLE ACROSS SOUTHERN NEVADA AND NORTHWEST ARIZONA. THE
STRONGEST WINDS LOOK TO OCCUR IN SAN BERNARDINO...CLARK AND MOHAVE
COUNTIES. A FIRE WEATHER WATCH WILL BE ISSUED FOR MONDAY WITH THIS
MORNINGS FIRE WEATHER PACKAGE.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...

     FOR NVZ461>464.
