AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
915 PM PDT SAT MAY 2 2009

.SYNOPSIS...WEAK HIGH PRESSURE WILL HOLD OVER THE REGION AS FAST
MOVING WEATHER DISTURBANCES BRUSH THE NORTHERN GREAT BASIN DURING
THE COMING WEEK. THIS DRY WEATHER PATTERN WILL PROVIDE OCCASIONAL
BREEZES AND ALLOW TEMPERATURES TO CLIMB WELL ABOVE NORMAL.
&&

.UPDATE...STRONG SURFACE PRESSURE GRADIENTS WITH DECENT LOW LEVEL
FLOW TO KEEP BREEZY/WINDY CONDITIONS ACROSS MUCH OF THE SAN
BERNARDINO DESERTS TONIGHT. HOWEVER WIDESPREAD WIND GUSTS MEETING
ADVISORY CRITERIA HAVE ENDED...THUS HAVE ALLOWED THE WIND ADVISORY
TO EXPIRE. GRADIENTS/FLOW ALOFT SHOWING LITTLE CHANGE FOR SUNDAY AND
WILL BE LOOKING AT ANOTHER ADVISORY POSSIBLY FOR SUNDAY IN THE NEXT
FORECAST PACKAGE. AT THE SAME TIME...DOWNSLOPE WINDS FORMED ALONG
THE SOUTHERN SIERRA WHICH RESULTED IN LOCALLY STRONG WINDS SATURDAY
AFTERNOON FOR THE WEST SIDE OF THE OWENS VALLEY AND VERY SIMILAR
CONDITIONS WILL ONCE AGAIN BE SEEN ON SUNDAY. MAIN CHANGE IS THAT
THE UPPER LEVEL JET SHIFTS SLIGHTLY NORTH FROM SATURDAY AFTERNOONS
POSITION. SIMILAR TO THE CALIFORNIA DESERTS...WILL BE LOOKING AT THE
POSSIBILITY OF WIND ADVISORIES FOR THE OWENS VALLEY FOR SUNDAY IN
THE NEXT PACKAGE TOO. ZONAL FLOW OVER THE CWA TONIGHT AND SUNDAY
WILL KEEP FAIRLY DIRTY CONDITIONS ACROSS THE AREA...THUS A PARTLY
CLOUDY/SUNNY SKY LOOKED FOR INTO SUNDAY. OVERALL CURRENT
FORECAST IS ON TRACK.  WILL UPDATE ZONES TO REMOVE HEADLINES AND
EVENING/MIDNIGHT WORDING...OTHERWISE NO ADDITIONAL UPDATES EXPECTED
THIS EVENING.
&&

.AVIATION...FOR MCCARRAN...WINDS TO REMAIN SOUTH TO SOUTHWEST
8-18KTS THROUGH 00Z MONDAY WITH CLOUDS GENERALLY AOA 25K FT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS GENERALLY SOUTH TO WEST 10-20KTS WITH HIGHER
WINDS ACROSS THE DAGGETT CORRIDOR THROUGH 00Z MONDAY. CLOUDS SCT-BKN
15K FT WITH BKN-OVC AOA 25K FT. ISOLATED SHOWERS AFTER 18Z SUNDAY
THROUGH 03Z MONDAY ALONG THE SOUTHERN SIERRA CREST.
&&

.PREV DISCUSSION...325 PM PDT SHORT TERM...SATELLITE IMAGERY SHOWED
A PACIFIC MOISTURE PLUME BETWEEN 30N AND 40N EXTENDING FROM THE WEST
COAST BACK TO THE DATE LINE. A ZONAL FLOW WILL BRING THIS MOISTURE
ACROSS THE FORECAST AREA...MAINLY IN THE FORM OF MID AND HIGH
CLOUDS...TONIGHT THROUGH TUESDAY. WEAK UPPER LOWS ROLLING ACROSS THE
PACIFIC NORTHWEST WILL BRUSH THE NORTHERN GREAT BASIN WILL HELP
ENHANCE AFTERNOON WEST TO SOUTHWEST BREEZES. ENOUGH MOISTURE COULD
MAKE IT NORTHERN LINCOLN COUNTY SUNDAY NIGHT FOR A SLIGHT CHANCE OF
PRECIP...BUT IT APPEARS MARGINAL AT BEST. WEST WINDS GUSTING OVER 40
MPH WILL CONTINUE ACROSS THE SAN BERNARDINO COUNTY DESERTS THIS
EVENING AND THE WIND ADVISORY WILL REMAIN IN EFFECT. HIGH
TEMPERATURES WILL CLIMB SEVERAL DEGREES BY SUNDAY AFTERNOON THEN
SHOULD FLUCTUATE ONLY A DEGREE OR TWO MONDAY AND TUESDAY. &&

.LONG TERM...MODELS REMAIN CONSISTENT WITH THE IDEA OF OUR WARMEST
WEATHER OF THE YEAR TAKING SHAPE THE LATTER HALF OF NEXT WEEK. AN
UPPER RIDGE OVER THE EASTERN PACIFIC CENTERED ALONG 27N WILL EXPAND
EASTWARD INTO THE SOUTHWESTERN UNITED STATES ON WEDNESDAY AFTERNOON.
BOTH THE 12Z ECMWF AND GFS HAVE TRENDED ABOUT 1C TO 2C WARMER WITH
TEMPS AT 700MB ON WEDNESDAY AFTERNOON...THUS HAVE BUMPED UP HIGHS A
LITTLE MORE THEN. BOTH THE 12Z GEM AND ECMWF ARE DROPPING A SYSTEM
ACROSS THE PAC NW ON THURSDAY WHICH MAY FLATTEN OUT OUR HEIGHTS SOME
BUT STILL WITH STRONG RIDGING CENTERED TO OUR SOUTH AND PLENTY OF
DRY AIR IN PLACE THE ONLY MAJOR EFFECT THIS SYSTEM COULD HAVE IS
SOME ENHANCEMENT OF WINDS THURSDAY AFTERNOON. OVERALL IT IS A TOUGH
CALL AS TO WHICH DAY MAY TURN OUT TO BE THE WARMEST BUT RIGHT NOW
THE CURRENT GRIDS SHOW THIS TO BE ON FRIDAY. HIGHS ARE EXPECTED TO
REACH 10 TO 15 DEGREES ABOVE NORMAL ACROSS THE AREA WITH THE WARMEST
SPOTS REACHING 100-110. FOR NOW...HAVE KEPT LAS VEGAS IN THE UPPER
90S...I GUESS I WOULD LIKE TO SEE PROGGED H5 HEIGHTS REACH AT LEAST
588 DM BEFORE FORECASTING A TRIPLE DIGIT HIGH HERE IN VEGAS.
AFTERWARDS HAVE LEANED TOWARDS THE 12Z ECMWF WHICH KEEPS A RIDGE
ACROSS THE SOUTHWESTERN UNITED STATES ALONG WITH 700 MB TEMPS THAT
ARE ABOUT 2C TO 3C WARMER THAN THE 12Z GFS. BY NEXT WEEKEND HEIGHTS
WILL STILL LIKELY LOWER AS ANOTHER SYSTEM DROPS SOUTHWARD OFF THE
COAST OF BRITISH COLUMBIA...WASHINGTON AND OREGON...BUT TEMPS ARE
STILL EXPECTED TO REMAIN ABOVE NORMAL. RECORD HIGH MINIMUM
TEMPERATURES MAY ALSO BE REACHED IN LAS VEGAS THURSDAY AND FRIDAY
MORNING.
