AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
853 PM PST TUE MAR 9 2010

.SYNOPSIS...THE FIRST STORM MOVES OUT OF THE AREA TONIGHT AS THE
SECOND SYSTEM MOVES RAPIDLY IN ON WEDNESDAY. THIS WILL RESULT IN
LOCAL GUSTY WINDS...SCATTERED RAIN AND SNOW SHOWERS OVER MAINLY THE
EASTERN PORTION OF THE SOUTHERN GREAT BASIN AND CONTINUED BELOW
NORMAL TEMPERATURES. DRYING AND WARMING TO TAKE PLACE INTO THE
WEEKEND AS A RIDGE OF HIGH PRESSURE THEN BUILDS OVER THE REGION.

.UPDATE...AS ONE STORM MOVES OUT OF NORTHWEST ARIZONA THIS
EVENING...THE NEXT IS MOVING INTO NORTHERN CALIFORNIA. THIS SECOND
SYSTEM WILL BE PRECEDED BY A BAND OF MID/HIGH CLOUDS TONIGHT AS
SATELLITE SHOWS THE LEADING EDGE OVERRUNNING THE FAR NORTHWEST ZONES
ALREADY. LATEST NAM/GFS IN GOOD AGREEMENT SLIDING TROUGH INTO THE
GREAT BASIN WEDNESDAY MORNING. THE TROUGH WILL SLOW AND DIG SOUTH
ACROSS LINCOLN/CLARK AND MOHAVE COUNTIES WEDNESDAY AFTERNOON AND
EVENING. THOSE THREE COUNTIES WILL LIE UNDER THE STRONGEST REGION OF
LIFT AND INSTABILITY AS WELL. TOMORROW AFTERNOON...WE ARE LOOKING AT
MORE GUSTY WEST WINDS ACROSS PORTIONS OF SAN BERNARDINO COUNTY AND
ALSO NORTHWEST WINDS BEHIND THE FRONTAL PASSAGE OVER NYE COUNTY.
WILL LET THE MIDSHIFT MAKE THE FINAL CALL ON AREAL EXTENT OF ANY
ADVISORIES. A RIDGE WILL BE OVER THE AREA THURSDAY WITH NORTH
BREEZES LINGERING DOWN THE COLORADO RIVER VALLEY. NO FURTHER UPDATES
PLANNED THIS EVENING.
&&

.AVIATION...FOR MCCARRAN...A BAND OF CLOUDS WITH CEILING ABOVE 15
KFT WILL BE ON THE INCREASE LATER TONIGHT AS THE NEXT STORM SYSTEM
MOVES INTO THE GREAT BASIN WEDNESDAY MORNING. THE SYSTEM WILL SLOW
SOME WEDNESDAY AFTERNOON AND EVENING AS SCATTERED SHOWERS ALONG WITH
A SLGT CHC OF THUNDERSTORMS DEVELOP IN THE MORMON MESA AND PEACH
SPRING CORRIDORS. IN THE LAS VEGAS VALLEY...THE COLD FRONTAL PASSAGE
WILL BE AROUND 23Z WITH CEILINGS BETWEEN 7 AND 9 KFT AGL. CLOUDS
WILL START TO SCATTER OUT WEDNESDAY EVENING AS HIGH PRESSURE BUILDS
IN THURSDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ANOTHER SHORTWAVE BRUSHES THE REGION WEDNESDAY
AFTERNOON AND EVENING WITH SCATTERED SHOWERS AND A SLGT CHC OF
THUNDERSTORMS IN LINCOLN...CLARK AND MOHAVE COUNTIES. ANOTHER
ROUND OF GUSTY WEST WINDS WILL IMPACT THE KDAG TOMORROW WHILE GUSTY
NORTH WINDS FOLLOWING THE COLD FRONT WILL IMPACT KBIH.
&&

.PREV DISCUSSION...300 PM PST TUE MAR 9...THE STRONG UPPER LOW
LOCATED OVER NORTHWEST ARIZONA AS OF 22Z TUESDAY WILL SHIFT EAST
TONIGHT. SOME WRAP AROUND MOISTURE TO KEEP ISOLATED/SCATTERED
SHOWERS MAINLY OVER MOHAVE COUNTY THROUGH THE EVENING BEFORE ENDING
OVERNIGHT. HOWEVER DO NOT EXPECT ADDITIONAL ACCUMULATIONS SO WILL
CANCEL THE WINTER ADVISORY FOR THIS AREA WITH THIS PACKAGE. THE NEXT
PACIFIC STORM IS ALREADY PUSHING INTO NORTHERN CALIFORNIA AND IS
EXPECTED TO MOVE RAPIDLY ACROSS THE SOUTHERN GREAT BASIN ON
WEDNESDAY. ATTM MOISTURE APPEARS TO BE FAIRLY LIMITED SO EXPECT LESS
ACTIVITY WITH THIS SYSTEM THAN WITH TODAYS STORM. WITH THIS SAID
THOUGH...LIGHT SNOW ACCUMULATIONS CAN STILL BE EXPECTED MAINLY
ACROSS THE SOUTHERN NEVADA MOUNTAINS. SIMILAR TO TODAYS
SYSTEM...COLD AIR ASSOCIATED WITH THIS STORM WILL ALLOW FOR LOW SNOW
LEVELS WHILE INSTABILITY WILL LIKELY PRODUCE ISOLATED THUNDERSTORMS
WEDNESDAY AFTERNOON. THIS SYSTEM IS FORECAST TO SHIFT INTO EASTERN
ARIZONA BY 06Z THURSDAY WITH RIDGE THEN BUILDING OVER THE CWA INTO
THURSDAY. STRONG AND GUSTY WINDS ACROSS THE SAN BERNARDINO COUNTY
DESERT TODAY SHOULD DECREASE SOMEWHAT OVERNIGHT. HOWEVER WITH THE
SECOND SYSTEM MOVING THROUGH THE AREA...EXPECT ANOTHER WINDY DAY ON
WEDNESDAY FOR THE WESTERN DESERTS. ADDITIONAL ENHANCEMENT OF THE
THERMAL GRADIENTS/PRESSURE GRADIENTS MAY ALSO INCREASE NORTH WINDS
IN THE OWENS VALLEY AND THE NORTHWEST PORTION OF THE CWA TO NEAR
ADVISORY LEVELS. FOR NOW WILL ONLY CONTINUE THE WIND ADVISORY FOR
THE SAN BERNARDINO DESERTS THROUGH THIS EVENING AND HAVE NOT
EXTENDED INTO WEDNESDAY AS WINDS SHOULD BE UNDER ADVISORY CRITERIA
THROUGHOUT MUCH OF THE NIGHT. WILL LIKELY NEED TO ISSUE A NEW
ADVISORY DURING THE NEXT PACKAGE FOR WEDNESDAY AFTERNOON AND WILL
ALSO BE MONITORING THE NORTHWEST PORTION OF THE CWA. COLD AIR THAT
MOVED OVER THE CWA TODAY WILL CONTINUE INTO WEDNESDAY WITH THE NEXT
SYSTEM...BEFORE WARMING TAKES PLACE ON THURSDAY AS THE RIDGE BUILDS
OVER THE REGION.

.LONG TERM...HIGH PRESSURE ON FRIDAY WILL DAMPEN SOMEWHAT ON
SATURDAY AS A TROUGH OF LOW PRESSURE BRUSHES ACROSS THE NORTHERN
EDGE OF THE FORECAST AREA. MODEL CONSENSUS WITH THIS FEATURE REMAINS
POOR...SO HAVE KEPT THE MIDDLE OF THE ROAD FORECAST IN PLACE...WHICH
RESULTS IN MINIMAL IMPACT TO THE REGION. THERE WILL ONLY BE A SLIGHT
CHANCE OF SHOWERS ACROSS THE HIGHER ELEVATIONS OF LINCOLN...NYE...
ESMERALDA...AND INYO COUNTIES. SUNDAY AND THROUGH THE FIRST HALF OF
NEXT WEEK...RIDGING WILL BUILD IN ACROSS THE REGION AND RESULT IN
MAINLY CLEAR SKIES AND TEMPERATURES WELL ABOVE NORMAL.
