AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
254 PM PDT MON JUN 9 2008

.SYNOPSIS...A COLD FRONT WILL MOVE THROUGH THE AREA LATE TUESDAY
AFTERNOON AND EVENING AND BRING WINDY CONDITIONS TO THE SOUTHERN
GREAT BASIN AND MOJAVE DESERT. TEMPERATURES WILL BE THE WARMEST OF
THE WEEK TUESDAY BEFORE DROPPING 10 TO 13 DEGREES ON WEDNESDAY
FOLLOWED BY A WARMING TREND FOR THE REST OF THE WEEK. PRECIPITATION
IS NOT ANTICIPATED THIS WEEK AND CLOUD COVER WILL BE MINIMAL AS
WELL.
&&

.SHORT TERM...PRIMARY CONCERN FOR THE NEXT DAY OR TWO WILL BE WINDS
ASSOCIATED WITH THE APPROACHING SYSTEM NOW COMING ASHORE IN SOUTHERN
BRITISH COLUMBIA. AHEAD OF THE SYSTEM SOUTHWEST WINDS WILL INCREASE
TO SPEEDS OR GUSTS STRONG ENOUGH TO WARRANT A RED FLAG OVER A LARGE
PART OF THE AREA AND SOME WIND ADVISORIES. MODELS AGREE ON PLACING
WINDS AROUND ADVISORY LEVEL IN WESTERN SAN BERNARDINO COUNTY AND
NORTHERN MOHAVE COUNTY TUESDAY AFTERNOON AND WENT AHEAD AND ISSUED
THEM. NEXT CONCERN IS WITH THE APPROACH AND PASSAGE OF THE COLD
FRONT THROUGH SOUTHERN NEVADA. UNLIKE LAST WEEKS SYSTEM MODELS DO
NOT WANT TO PUSH THIS ONE RAPIDLY THROUGH THE LAS VEGAS VALLEY.
FORECAST PRESSURE GRADIENTS ARE FORECAST TO BE STRONG BEHIND THE
FRONT...NOT AS STRONG AS LAST WEDNESDAY THOUGH. HAVE ISSUED A HIGH
WIND WATCH FOR SOUTHERN NEVADA ZONES FOR POST FRONTAL NORTH WINDS.
THINK THE BEST CHANCE WILL BE ON THE NEVADA TEST RANGE WITH GUSTS
MOST LIKELY THE CAUSE OF VERIFICATION.

PRETTY MUCH KEPT THE EXISTING TEMPERATURE FORECAST. TUESDAY WILL SEE
A WARM UP AS SOUTHWEST FLOW MIXES DOWN. THE DECENT THERMAL PACKING
BEHIND THE FRONT SHOULD DRAG WEDNESDAYS TEMPERATURES DOWN A FAIR
AMOUNT AS PREVIOUSLY FORECAST. DRY NORTHWEST FLOW BEHIND THE FRONT
WILL GIVE WEAK TO RIDGING OVER THE AREA BY FRIDAY AND A WARMING
TREND.

.LONG TERM...NORTHWEST FLOW WILL CONTINUE ACROSS THE AREA THURSDAY
BEHIND THE DEPARTING SYSTEM. 1000-500 MB THICKNESSES BASICALLY STAY
FLAT OR RISE A LITTLE AND 700 MB TEMPS WARM BY AROUND 1C OVER
WEDNESDAY WHICH SHOULD ALLOW FOR A SUBTLE WARMING TREND. THE MEX AND
SOME OF THE OTHER MODEL GUIDANCE HAS APPARENTLY WOKE UP AND STARTING
SMELLING THE ROSES THAT THESE KINDS OF TRENDS PLUS A NW FLOW ALOFT
WILL NOT BE ENOUGH TO CAUSE A 7 DEGREE OR SO JUMP IN HIGH TEMPS LIKE
THEY HAVE BEEN SHOWING THE PAST TWO DAYS IN THEIR FORECAST FOR
THURSDAY. SO BASICALLY GUIDANCE IS NOW CLOSER TO THE FORECAST.
LATEST WRF FORECAST FOR THURSDAY ALSO SHOWS MORE OF A NORTHEAST SFC
P-GRAD STILL LINGERING...SO WILL HAVE TO WATCH FOR SOME LINGERING
NORTH BREEZES IN THE EASTERN HALF OF THE AREA...ESPECIALLY DOWN THE
RIVER. NORTHWEST FLOW ALOFT STILL HOLDS AS FRIDAY DAWNS...THEN
FLATTENS OUT AS AN UPPER RIDGE CENTERED OVER NORTHERN MEXICO AND
SOUTHERN PORTIONS OF AZ/NM BUILDS NORTHWARD INTO THE SW CONUS. THUS
WE SHOULD SEE A MARKED RISE IN TEMPERATURES ON FRIDAY AFTERNOON.
OVER THE WEEKEND THIS RIDGE LOOKS TO BUILD NORTHWARD INTO THE SW
CONUS AND AMPLIFY THE UPPER FLOW. JUST HOW MUCH THOUGH DIFFERS
BETWEEN THE ECMWF AND THE OPERATIONAL GFS AND THE GFS ENSEMBLES. THE
ECMWF IS BUILDING IN A MUCH STRONGER RIDGE AND ALSO IS QUICKER TO
WARM TEMPS ALOFT AS WELL...ESPECIALLY SATURDAY. HAVE BLENDED THE
PREVIOUS FORECAST HIGHS WITH THE LATEST ECMWFBC GUIDANCE AND THUS
THIS BUMPED UP PROGGED MAXES BY A DEGREE OR TWO. WE SHOULD SEE A
STREAK OF TRIPLE DIGIT HIGHS IN THE LV VALLEY THAT STARTS OFF
SATURDAY AS 700 MB TEMPS RISE TO +12C TO +14C. FURTHER WARMING WILL
TAKE PLACE INTO SUNDAY WITH 700 MB TEMPS FORECAST TO REACH +14C TO
+16C. BY MONDAY...700 MB TEMPS ARE PROGGED TO BE +14C TO +17C AND
TEMPS WILL WARM A HAIR MORE. DEPENDING ON HOW STRONG OF RIDGE WE SEE
IT MAY BEGIN TO WEAKEN BY TUESDAY. EITHER WAY IT LOOKS LIKE WE
FINALLY WILL SEE MORE SUMMER LIKE WEATHER ACROSS THE AREA. AS FOR
SKY COVER...MODELS KEEP RH VALUES LOW IN CROSS SECTIONS THROUGH THE
PERIOD...SO FEW IF ANY CLOUDS ARE EXPECTED.
&&

.AVIATION...FOR MCCARRAN...VARIABLE TO SOUTHWEST WINDS THIS EVENING
INTO TONIGHT AT 6-10 KTS. AROUND 17Z TUE...WINDS SHOULD BEGIN TO
PICK UP OUT OF THE SOUTHWEST AS A COLD FRONT BEGINS TO APPROACH THE
AREA FROM THE NORTHWEST. WINDS WILL INCREASE TO 20-25 KTS SUSTAINED
WITH GUSTS UP TO 45 KTS. A FEW HIGH CLOUDS THIS EVENING AND
TONIGHT...AND FEW-SCT HIGH CLOUDS TOMORROW. THE FRONT LOOKS TO MOVE
THROUGH WEDNESDAY MORNING AND THEN WINDS LOOK TO SHIFT TO THE
NORTHWEST. THERE LOOKS TO BE A PERIOD OF WINDS JUST BEHIND THE FRONT
WHERE SUSTAINED WINDS OF 20-30 KTS WITH GUSTS TO AROUND 45 KTS IS
POSSIBLE. AS THE WINDS PICK UP AREAS OF BLOWING SAND AND DUST COULD
LIMIT VSBY AT TIMES. MECHANICAL TURBULENCE IS POSSIBLE TUE AFTERNOON
INTO WED MORNING ESPECIALLY IN AREAS OF ROUGH TERRAIN.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...VARIABLE WINDS THIS EVENING INTO TONIGHT GENERALLY AT
10 KTS OR LESS. THE EXCEPTION WILL BE ACROSS THE SOUTHERN GREAT
BASIN INTO THE VCTY OF KDRA WHERE AHEAD OF AN APPROACHING SYSTEM
WINDS WILL BE GENERALLY BE OUT OF THE SOUTHWEST. AS THIS SYSTEM
WORKS ACROSS THE PACIFIC NW TOMORROW IT WILL DRAG A COLD FRONT
TOWARDS THE AREA AND WINDS WILL INCREASE OUT OF THE SOUTHWEST TO
WEST AHEAD OF THE FRONT...EXCEPT IN THE OWENS VALLEY WHERE THE LOOK
TO STAY NORTHERLY. SOUTHWEST TO WEST WINDS OF 20-35 KTS WITH GUSTS
TO AROUND 45 KTS ARE EXPECTED WITH THE HIGHEST WINDS LIKELY IN THE
WESTERN SAN BERNARDINO COUNTY DESERTS INCLUDING KDAG. THESE GUSTY
WINDS WILL ALLOW FOR AREAS OF BLOWING DUST/SAND THAT COULD REDUCE
VSBY TO MVFR LEVELS OR LOWER. THE COLD FRONT LOOKS TO MOVE ACROSS
THE AREA LATER TUESDAY NIGHT INTO WEDNESDAY MORNING. WINDS WILL THEN
BECOME NORTHWEST BEHIND THE FRONT AND BE RATHER GUSTY WITH SUSTAINED
SPEEDS OF 20-35 KTS EXPECTED AND THE STRONGEST GUSTS IN EXCESS OF 45
KTS. THE STRONGEST POSTFRONTAL WINDS ARE EXPECTED IN THE SOUTHERN
GREAT BASIN INTO THE LAS VEGAS VALLEY. AGAIN...AREAS OF BLOWING DUST
AND SAND COULD ALLOW FOR REDUCED VSBY. WINDS WILL GRADUALLY LESSEN
BY LATER ON WEDNESDAY. MECHANICAL TURBULENCE IS POSSIBLE TUE
AFTERNOON INTO WED MORNING ESPECIALLY IN AREAS OF ROUGH TERRAIN.
&&

.FIRE WEATHER...AN APPROACHING FRONT WILL BRING STRENGTHENING
SOUTHWEST TO WEST WINDS TUESDAY ACROSS THE REGION. FUELS ARE VERY
DRY MOST LOCATIONS EXCEPT FOR THE SOUTHERN MOUNTAINS OF NEVADA. WENT
AHEAD ISSUED A RED FLAG FOR ALL OF OUR NEVADA ZONES EXCEPT THE
SOUTHERN MOUNTAINS WHERE FUEL MOISTURE IS HIGH. REMOVED THE COLORADO
RIVER VALLEYS DUE THE WINDS NOT EXPECTED TO REACH REQUIRED STRENGTH
IN A SOUTHWEST FLOW. AZ102 WILL HAVE THE BEST CHANCE OF CRITERIA IN
THE NORTHERN PART.  HAVE ADDED CAZ228 AS WESTERN SAN BERNARDINO
COUNTY WILL HAVE VERY STRONG WINDS COMBINED WITH THE LOW RH AND DRY
FUELS. &&
