AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
334 AM PDT SUN MAR 30 2008

.SYNOPSIS...A PACIFIC STORM WILL MOVE ACROSS THE SOUTHERN GREAT
BASIN AND MOJAVE DESERT TODAY PRODUCING WINDY CONDITIONS ACROSS
EASTERN CALIFORNIA AND NORTHWEST ARIZONA. THE BEST CHANCE OF SHOWERS
WILL BE ACROSS NYE AND LINCOLN COUNTIES WITH A SLIGHT CHANCE AS FAR
SOUTH AS CLARK COUNTY. IMPROVED CONDITIONS WILL BE SEEN MONDAY AND
TUESDAY BEFORE THE NEXT SYSTEM MOVES INTO THE AREA ON WEDNESDAY.
&&

.SHORT TERM...SATELLITE SHOWS NEXT AREA OF ENHANCED CLOUDS
DEVELOPING IN THE LEE OF THE SOUTHERN SIERRA OVER INYO COUNTY AND
CENTRAL NEVADA AHEAD OF SHORTWAVE TROUGH APPROACHING THE CENTRAL
CALIFORNIA COAST. MODELS CONSISTENT SWINGING SHORTWAVE TROUGH ACROSS
THE SOUTHERN GREAT BASIN AND MOJAVE DESERT TODAY. SO FAR...ONLY A
TRACE OF PRECIPITATION HAS BEEN REPORTED ACROSS CENTRAL NYE COUNTY
WHILE PIOCHE IN NORTHERN LINCOLN COUNTY REPORTED 0.01 OF AN INCH
BETWEEN 1 AND 2 AM. AGAIN...NAM/GFS SIMILAR DEVELOPING A BAND OF
HIGHER QPF AMOUNTS EXTENDING FROM CENTRAL NYE COUNTY ACROSS NORTHERN
LINCOLN COUNTY THIS AFTERNOON WITH MUCH LIGHTER AMOUNTS JUST
SKIRTING THE NORTHERN PORTION OF CLARK COUNTY. THE SNOW LEVEL WILL
REMAIN ABOVE 6500 FEET TODAY WITH ANY ACCUMULATIONS LIKELY OCCURRING
ABOVE 7000 FEET. IMPACTS ON LINCOLN COUNTY WILL BE NEGLIGIBLE WITH
SNOW LEVELS THAT HIGH. DID INCLUDE THE MENTION OF A SLIGHT CHANCE OF
THUNDERSTORMS FOR LINCOLN AND NORTHERN MOHAVE COUNTIES THIS
AFTERNOON IN AREA OF STEEPEST MID-LEVEL LAPSE RATES. WIND IS THE
NEXT CONCERN. STRONGEST BELT OF 700 MB WINDS PROGGED TO RUN
OVER NORTHERN SAN BERNARDINO AND CENTRAL AND NORTHERN MOHAVE
COUNTIES WHILE TIGHTEST SURFACE PRESSURE GRADIENT LIES ACROSS
WESTERN SAN BERNARDINO COUNTY. THE STRONG WIND WILL LAST LONGER IN
SE CALIFORNIA SO HAVE WIND ADVISORY RUNNING UNTIL MIDNIGHT...WHILE
IN MOHAVE COUNTY THE ADVISORY ENDS AT 8 PM MST THIS EVENING. SHOWERS
WILL TAPER OFF OVERNIGHT AS TROUGH SHIFTS EAST ACROSS UTAH AND
ARIZONA. FORECAST AREA WILL LIE UNDER WEAK RIDGE MONDAY AND TUESDAY
WITH NEXT SYSTEM APPROACHING THE SOUTHERN CALIFORNIA COAST TUESDAY
NIGHT. THERE ARE TIMING DIFFERENCE BETWEEN THE GFS/ECMWF WITH THIS
SYSTEM BUT DOES NOT LOOK LIKE IT WILL MATTER AS MODELS BRING A
WEAKENING TROUGH INLAND WEDNESDAY. TEMPERATURES SHOULD BE WITHIN A
FEW DEGREES OF CLIMATOLOGICAL NORMALS TODAY...MONDAY AND TUESDAY.

.LONG TERM...ALTHOUGH CONFIDENCE REMAINS DECENT THAT A SYSTEM WILL
AFFECT THE AREA WEDNESDAY...MODELS CONTINUE TO DIFFER IN THEIR
SOLUTIONS. THE GFS REMAINS CONSISTENT IN TRACKING THE SYSTEM ACROSS
THE CWA WHILE THE ECMWF NOW TAKES THE TROUGH ALONG THE MEXICAN
BORDER. DECIDED TO STAY WITH THE GFS IDEA DUE TO BETTER RUN-TO-RUN
CONSISTENCY AND SUPPORT FROM THE GEM AND GFS ENSEMBLE MEAN. THIS
NECESSITATED AN INCREASE IN POPS OVER THE NORTHERN REGIONS OF THE
AREA AND A LOWERING OF TEMPS PRETTY MUCH EVERYWHERE. THE ECMWF
BRINGS A SHARP TROUGH FROM THE NORTHERN GREAT BASIN INTO UTAH
THURSDAY DRAWING A SURFACE COLD FRONT THROUGH THE REGION. THE GFS
AGAIN HAS BEEN MORE CONSISTENT IN KEEPING THE ENERGY WELL NORTH WITH
NO EVIDENCE OF A FRONTAL PASSAGE. RIDGING IS FORECAST FOR FRIDAY
WITH LIGHT WIND AND WARMER TEMPERATURES. THE GFS BRINGS ANOTHER
SYSTEM NEAR THE SOUTHERN CAL COAST SATURDAY WHICH COULD POTENTIALLY
INCREASE WIND AND CLOUD COVER. HOWEVER...THE EURO HAS THE SYSTEM 700
MILES FURTHER WEST AND RIDGING OVER THE AREA AT THAT SAME TIME
PERIOD.
&&

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS EXPECTED TO CONTINUE
THROUGH THE REST OF THE NIGHT WITH GUSTS TO AROUND 20KTS. A STORM
WILL PASS ACROSS THE AREA TODAY BRINGING AN INCREASE IN WIND TO
KLAS. PREVAILING SOUTHWEST WINDS 20 TO 30 KTS WITH GUSTS UP TO 40
KTS POSSIBLE. SHOWER ACTIVITY WITH ISOLATED THUNDERSTORMS ARE
EXPECTED TO REMAIN NORTH OF THE LAS VEGAS AREA BUT COULD IMPACT THE
BEATTY AND MORMON MESA CORRIDORS. MODERATE MECHANICAL TURBULENCE CAN
BE EXPECTED ALONG ALL APPROACH CORRIDORS THROUGH THIS AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...STRONG SOUTHWEST WINDS WILL CONTINUE ACROSS SAN
BERNARDINO...CLARK...AND MOHAVE COUNTIES THROUGH THIS AFTERNOON AS A
STORM PASSES THROUGH THE AREA. GUSTS APPROACHING 50 KTS ARE POSSIBLE
IN FAVORED AREAS. SHOWER ACTIVITY SHOULD REMAIN OVER THE NORTHERN
REGIONS
