AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
924 PM PDT THU MAY 26 2011

.SYNOPSIS...DRY AND WINDY CONDITIONS ARE EXPECTED ONCE AGAIN ON
FRIDAY. AN AREA OF LOW PRESSURE WILL MOVE SOUTH TOWARDS NORTHERN
NEVADA ON SATURDAY AND THEN ACROSS THE AREA ON SUNDAY RESULTING IN
MORE GUSTY WINDS AS WELL AS AN INCREASE IN CLOUDS. THE STRONGEST
WINDS ARE EXPECTED TO BE SATURDAY NIGHT INTO SUNDAY. SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS WILL ALSO BE POSSIBLE SATURDAY
NIGHT INTO SUNDAY NIGHT IN THE SOUTHERN GREAT BASIN. ANOTHER ROUND
OF GUSTY WINDS IS POSSIBLE STARTING ON TUESDAY.
&&

.UPDATE...AFTER PEAKING IN THE LATE AFTERNOON AND EARLY
EVENING...WINDS ACROSS THE WESTERN MOJAVE DESERT OF SAN BERNARDINO
COUNTY BEGINNING TO SHOW SIGNS OF DECREASING. DID TWEAK SPEEDS AND
GUSTS IN THIS EVENINGS UPDATE.

WINDS WILL AGAIN INCREASE LATE FRIDAY AFTERNOON AND EVENING. WILL
HOLD OFF ON ANY HEADLINES AT THIS TIME. OVERALL PATTERN WILL CHANGE
LITTLE OVER THE NEXT 24 HOURS. ZONAL FLOW ALOFT WILL CONTINUE WITH
POWERFUL JET OF 140-160 KNOTS FOR LATE MAY RUNNING NEARLY PARALLEL
TO THE NORTHERN NEVADA BORDER. JET BUCKLES ALONG THE WEST COAST
SATURDAY AS TROUGH DIGS INTO THE GREAT BASIN WITH MODELS PLACING AN
UNSEASONABLY DEEP/COLD UPPER LOW NEAR SOUTH LAKE TAHOE SUNDAY
MORNING. OUR MAIN ISSUE THIS HOLIDAY WEEKEND WILL BE STRONG
SOUTHWEST TO WEST WINDS FOR THE HIGH DESERT OF SAN BERNARDINO COUNTY
AND MOHAVE COUNTY ARIZONA. RIGHT NOW...MUCH OF SOUTHERN NEVADA MAY
BE SPARED FROM THE REALLY STRONG SOUTHWEST WINDS BUT DON'T GET ME
WRONG IT WILL STILL BE BREEZY TO WINDY. THE OTHER ISSUE WILL BE THE
DRAMATIC DROP IN TEMPERATURES BETWEEN SATURDAY AND SUNDAY. IF THE
12Z GFS MODEL IS CORRECT WE COULD BE FLIRTING WITH RECORD LOW
MAXIMUM TEMPERATURES FOR THE SECOND TIME IN THE PAST WEEK AND A
HALF.
&&

.PREV DISCUSSION...
351 PM PDT THU MAY 26 2011

.SHORT TERM...WE ARE IN A LITTLE BREAK FOR NOW WITH THE PREVIOUS
SYSTEM HAVING MOVED ON INTO WYOMING AND COLORADO AND THE NEXT
SYSTEM OFF THE COAST OF THE PAC NW. CIRRUS HAS LINGERED MUCH OF
THE DAY ACROSS THE MOJAVE DESERT AS HIGHER LEVEL MOISTURE HAS
GOTTEN STRUNG OUT ON THE BOTTOM OF THE TROUGH. OVERALL MODELS SHOW
SOME DRYING TAKING PLACE ALOFT NOW THAT WESTERLY FLOW ALOFT HAS
SET UP AND WE SHOULD SEE MOST OF THE CIRRUS CLEAR OUT OF SOUTHERN
PARTS OF THE AREA TONIGHT. WINDS REMAIN GUSTY...BUT WITH
WIDESPREAD ADVISORY WINDS NOT BEING OBSERVED IN NW SAN BERNARDINO
COUNTY THE WIND ADVISORY WAS CANCELLED THERE.

FOR FRIDAY WESTERLY FLOW ALOFT SETS UP KEEPING DRY CONDITIONS IN
PLACE. ALTHOUGH WINDS WILL PICK UP IN THE AFTERNOON FROM THE
SOUTHWEST TO WEST...700 MB WINDS ARE NOT FORECAST TO BE MUCH
HIGHER THAN 35 KTS...WITH THE ECMWF SHOWING EVEN LIGHTER WINDS.
WHILE IT WILL GET WINDY TOMORROW AFTERNOON ONCE AGAIN...ESPECIALLY
IN NW SAN BERNARDINO COUNTY...IT DOES NOT LOOK LIKE WE WILL SEE
THE SUPPORT ALOFT FOR WIDESPREAD ADVISORY LEVEL WINDS AND
THEREFORE I DID NOT ISSUE ANY HEADLINES. TEMPS WILL WARM TO ABOVE
NORMAL UNDER A DECENT AMOUNT OF SUNSHINE.

THE NEXT BIG EVENT WILL COME THIS WEEKEND AS THE NEXT SYSTEM DROPS
SOUTHEAST TOWARDS NORTHERN NEVADA. SOUTHWEST FLOW WILL STRENGTHEN
ACROSS THE AREA ON SATURDAY AND OVERALL HEIGHT FALLS WILL SUPPORT
TEMPS A LITTLE COOLER THAN TOMORROW WHICH WOULD PUT THEM CLOSER TO
NORMAL OR A LITTLE BELOW. HOWEVER...THE MAIN ISSUE WILL BE GUSTY
WINDS STARTING IN THE AFTERNOON AS SURFACE PRESSURE GRADIENTS
TIGHTEN AND WINDS ALOFT INCREASE TO 35 TO 50 KTS OVER THE MOJAVE
DESERT. WIND GUSTS OF 40 TO 55 MPH LOOK LIKELY OVER A LARGE PART
OF THE AREA AND WIND ADVISORIES LOOK A LOCK. AREAS OF BLOWING DUST
AND SAND WILL ALSO OCCUR ESPECIALLY NEAR DRY LAKE BEDS AND SAND
DUNES. WE DID NOT ISSUE ANY HEADLINES AT THIS TIME AS WINDS LOOK
TO KEEP ON GOING RIGHT INTO SUNDAY IN MANY AREAS AND THERE MAY NOT
BE MUCH OF A LULL SATURDAY NIGHT. SOME AREAS COULD SEE WARNING
LEVEL GUSTS. THE HIGHEST WINDS SUNDAY LOOK TO BE IN THE MORNING
AND EARLY AFTERNOON...WITH WINDS DROPPING OFF BY THE LATE
AFTERNOON IN THE WAKE OF THE TROUGH PASSAGE. WITH THE CONCERN FOR
PEOPLE VENTURING OUT TO AREA LAKES THIS HOLIDAY WEEKEND AND GUSTY
WINDS FORECAST...WE HAVE ISSUED A GRAPHIC ON OUR WEBSITE TO
HIGHLIGHT THIS POTENTIAL HAZARD.

SHOWERS AND ISOLATED THUNDERSTORMS LOOK TO MOVE INTO THE SOUTHERN
GREAT BASIN LATE SATURDAY NIGHT AND ESPECIALLY ON SUNDAY. BOTH
THE WRF AND GFS SHOW SOME FRONTOGENETIC BAND OF PRECIPITATION
SETTING UP SUNDAY AFTERNOON OVER CENTRAL NYE COUNTY...THUS RAISED
POPS IN THIS AREA AS WELL AS INTO LINCOLN COUNTY. THE SOUTHERN
EXTENT OF SUFFICIENT MOISTURE FOR PRECIPITATION LOOKS TO BE A
SHARP-CUT OFF RIGHT NEAR CLARK COUNTY...SO HAVE A BIG DROP OFF IN
POPS THEN. MUCH COLDER WEATHER WILL ARRIVE BY SUNDAY AFTERNOON IN
THE WAKE OF THE TROUGH AND HIGHS WILL DROP A GOOD 15 DEGREES FROM
SUNDAY. SNOW LEVELS ARE FORECAST TO DROP TO NEAR 6000 FEET BY
SUNDAY NIGHT...SO SOME HIGHER ELEVATIONS COULD SEE A LIGHT COATING
OF SNOW IN HEAVIER SNOW SHOWERS.

.LONG TERM...MODELS INDICATE THAT THE UPPER LOW WILL SHIFT NORTHEAST
OUT OF THE AREA SUNDAY NIGHT FOLLOWED BY WEAK RIDGING ON MONDAY.
THIS WILL BRING LIGHTER WINDS BACK INTO THE AREA ALONG WITH WARMING
TEMPERATURES. ANOTHER STRONGER LOW IS FORECAST TO DROP DOWN THE WEST
COAST MONDAY NIGHT AND TUESDAY BRINGING GUSTY WINDS BACK INTO THE
FORECAST TUESDAY AFTERNOON. MODELS ARE ALSO IN AGREEMENT THAT A
STRONG AREA OF HIGH PRESSURE WILL DEVELOP OVER THE SOUTHERN PORTIONS
OF THE U.S. WHICH WOULD KEEP THE LOW HANGING OFF SHORE FOR SEVERAL
DAYS. THE EXACT SETUP OF BOTH THE HIGH AND LOW ARE STILL IN
QUESTION...BUT IF THE MODELS ARE RIGHT WITH THE CURRENT RUNS...THEN
WE ARE LOOKING FOR ABOUT A 5 DAY PERIOD OF WINDY CONDITIONS. THIS
WOULD ALSO BRING MUCH WARMER TEMPERATURES BACK INTO THE AREA WITH
READINGS A FEW DEGREES ABOVE NORMAL BY THE END OF NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...WINDS ARE EXPECTED TO BE FROM THE
SOUTHWEST THE REST OF TONIGHT WITH SPEEDS OF 10-13 KTS WITH
OCCASIONAL GUSTS OF 20 KTS. SOUTHWEST WINDS AROUND 10-15KTS WITH A
GUST UP TO 25 KTS POSSIBLE FRIDAY. SCT CLOUDS AOA 25K FEET THROUGH
FRIDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WEST TO NORTHWEST WINDS AROUND 10-20KTS ACROSS NORTHERN
AND WESTERN AREAS AND SOUTHWEST 10-20KTS OVER THE SOUTHERN AND
EASTERN PORTIONS. THE ONLY EXCEPTION WITH BE AROUND KDAG WHERE GUSTS
AROUND 40KTS ARE POSSIBLE LATE FRIDAY AFTERNOON AND EVENING.
VARIABLE UPPER LEVEL CLOUD COVERAGE CAN BE EXPECTED.
&&

.FIRE WEATHER...A LOW PRESSURE SYSTEM WILL DROP SOUTH OUT OF THE PAC
NW AND SETTLE IN OVER NORTHERN NEVADA ON SATURDAY...WHICH WILL
RESULT IN STRONG SOUTHWESTERLY WINDS ACROSS THE MOJAVE DESERT ON
SATURDAY. WITH WIDESPREAD RELATIVE HUMIDITY VALUES BELOW 15 PERCENT
EXPECTED...HAVE ISSUED A FIRE WEATHER WATCH FOR CALIFORNIA ZONES 228
AND 229...NEVADA ZONES 465 AND 466...AND ARIZONA ZONES 101 AND 102
FOR SATURDAY AFTERNOON. THERE IS SOME POSSIBILITY THAT CRITICAL
CONDITIONS MAY BE MET AGAIN ON SUNDAY AFTERNOON MAINLY OVER
SOUTHERN NEVADA AND NORTHWEST ARIZONA AS RELATIVE HUMIDITY VALUES
WILL BE CLOSE TO OR BELOW 15 PERCENT AND GUSTY WINDS ARE ONCE
AGAIN EXPECTED...HOWEVER THE LOW HUMIDITIES LOOK TO BE IN A
SMALLER AMOUNT OF THE AREA.
