AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
413 AM PDT SUN MAR 8 2009

.SYNOPSIS...AN AREA OF LOW PRESSURE OVER WESTERN CANADA WILL SAG
SOUTH INTO THE PACIFIC NORTHWEST TODAY AND THEN SOUTHEAST ACROSS
NEVADA ON MONDAY. THIS WILL RESULT IN BREEZY TO WINDY CONDITIONS
ACROSS THE REGION ON MONDAY WITH SCATTERED SHOWERS MAINLY ACROSS
LINCOLN COUNTY MONDAY AFTERNOON. THE LOW WILL QUICKLY EXIT THE AREA
MONDAY NIGHT. THE REMAINDER OF THE WEEK WILL BE DRY WITH
TEMPERATURES WARMING TO ABOVE NORMAL.
&&

.SHORT TERM...DRY WESTERLY FLOW ALOFT ACROSS THE CWA TODAY AS NEXT
SHORTWAVE DROPS SOUTH FROM CANADA AND INTO NORTHERN NEVADA DURING
THE DAY. SHORTWAVE TO THEN CONTINUE SOUTHEAST TONIGHT/MONDAY WITH
POSSIBLE SHOWERS GENERALLY CONFINED TO THE LINCOLN COUNTY AREA
MONDAY AFTERNOON AND THEN INTO NORTHERN MOHAVE COUNTY MONDAY EVENING
BEFORE THE SHORTWAVE SHIFTS EAST MONDAY NIGHT. NAM/GFS IN GOOD
AGREEMENT ON THIS FEATURE...BUT OVERALL THE 06Z RUN OF THE GFS HAS
BECOME MORE AGGRESSIVE WITH THE PRECIPITATION THAN THE NAM WITH
SHOWERS POSSIBLY FORMING FURTHER WEST. FOR NOW HAVE CONTINUED WITH
PREVIOUS TREND OF THE FORECAST AS MENTIONED ABOVE. THE MAIN CONCERN
WITH THIS SYSTEM WILL BE WINDS. AS THE SYSTEM DROPS SOUTH DURING THE
DAY...LOOK FOR INCREASING FLOW ACROSS THE SOUTHERN SIERRA.  ALTHOUGH
IT LOOKS VERY GOOD FOR STRONG/GUSTY WINDS OVER THE SOUTHERN SIERRA
CREST...STILL QUESTIONABLE IF WINDS WILL SURFACE IN THE OWENS VALLEY
ON MONDAY. WILL ISSUE A HIGH WIND WATCH WITH THIS PACKAGE FOR THE
EAST SLOPES/OWENS VALLEY BEGINNING LATE TONIGHT AND GOING THROUGH
MONDAY AFTERNOON. THE NEXT CONCERN WILL BE WINDS ACROSS THE SOUTHERN
DESERT AREAS MONDAY AFTERNOON. INCREASE PRESSURE GRADIENTS/
700...850MB FLOW ALL POINT TO STRONG/GUSTY WINDS ACROSS MUCH OF SAN
BERNARDINO COUNTY/SOUTHERN NEVADA/MOHAVE COUNTY BY EARLY MONDAY
AFTERNOON INTO EARLY EVENING. STILL A LITTLE EARLY FOR A WIND
ADVISORY BUT WILL LIKELY NEED ONE IN LATER PACKAGES. AS THE
SHORTWAVE SHIFTS EAST MONDAY NIGHT...WINDS TO DECREASE. DRY
NORTHWEST TO WEST FLOW WILL ONCE AGAIN FORM ACROSS THE CWA ON
TUESDAY AND CONTINUE INTO 12Z WEDNESDAY. TEMPERATURES ACROSS THE CWA
WILL BE A CHALLENGE DURING THE SHORT TERM. COOL TEMPS ON SATURDAY
HAVE RESULTED IN A COOLER STARTING POINT FOR TODAY...HOWEVER A
SWITCH TO SOUTHERLY FLOW TODAY SHOULD BRING WARMING AND THEN
ADDITIONAL WARMING ON MONDAY ESPECIALLY ACROSS THE SOUTH WITH THE
STRONGER WINDS/MIXING. HOWEVER THE ASSOCIATED COLD FRONT...EXPECTED
ACROSS EXTREME SOUTHERN NEVADA AROUND 06Z TUESDAY...WILL ONCE AGAIN
BRING NORTH FLOW AT THE SURFACE/COOLING INTO TUESDAY. OVERALL
TRENDED TOWARDS A BLEND OF THE NAM/GFS WITH MONDAY BEING THE WARMEST
AND TUESDAY COOLING SLIGHTLY.

.LONG TERM...POOR CONSENSUS AMONG THE FORECAST MODELS CONTINUES TO
BE AN ISSUE TOWARDS THE END OF THE EXTENDED PERIOD...BUT
OVERALL...NOT MUCH CHANGE WAS NEEDED THIS EVENING TO INHERITED
GRIDS. MORE EMPHASIS WAS PLACED ON THE OPERATIONAL EC...BASED ON
ENSEMBLE SPREADS...RECENT PERFORMANCE...AND LARGE SCALE
TELECONNECTIONS. A MID/UPPER LEVEL AREA OF LOW PRESSURE WILL PASS
OVER THE AREA THURSDAY/FRIDAY...BUT WILL HAVE MINIMAL IMPACT ON
TEMPS...AND ONLY RESULT IN A SLIGHT INCREASE IN CLOUDS. RIDGING WILL
PERSIST THROUGH THE WEEKEND...KEEPING TEMPS ABOVE NORMAL BUT BY THE
BEGINNING OF NEXT WEEK...A DEEP TROUGH MAY BE JUST OFF THE WEST
COAST. HAVE INCREASED POPS AND CLOUD COVER...AND DECREASED TEMPS
SLIGHTLY DURING THE BEGINNING OF NEXT WEEK...BUT WILL NEED TO
CONTINUE THIS TREND IN FUTURE PACKAGES IF THE EC SHOWS GOOD
CONTINUITY.
&&

.AVIATION...FOR MCCARRAN...WINDS WILL REMAIN RELATIVELY LIGHT
TODAY....BUT BEGIN TO INCREASE LATE AFTERNOON/TONIGHT OUT OF THE
SOUTHWEST AS A LOW PRESSURE SYSTEM APPROACHES FROM THE NORTHWEST.
WIND SPEEDS WILL BE MUCH STRONGER BY MONDAY AFTERNOON...WITH GUSTS
OVER 30KTS EXPECTED.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A LOW PRESSURE SYSTEM APPROACHING FROM THE NORTH WILL
RESULT IN INCREASING SOUTHWEST WINDS OVER THE NEXT 48
HOURS. WINDS SPEEDS WILL BE STRONGEST MONDAY...WITH GUSTS OVER 40
KTS LIKELY...ESPECIALLY IN AREAS PRONE TO SOUTHWEST WINDS.
&&

.FIRE WEATHER...STRONG AND GUSTY WINDS WILL BE FORMING ACROSS THE
SOUTHERN PORTION OF THE DISTRICT ON MONDAY AS ANOTHER LOW PRESSURE
SYSTEM MOVES INTO AND ACROSS THE AREA. WIND GUSTS IN EXCESS OF 40
MPH ARE LIKELY BY EARLY MONDAY AFTERNOON ACROSS SAN BERNARDINO
COUNTY EAST INTO SOUTHERN NEVADA AND NORTHWEST ARIZONA. HOWEVER
MINIMUM RELATIVE HUMIDITIES ARE EXPECTED TO REMAIN IN THE 15-20
PERCENT RANGE MONDAY AFTERNOON THUS WILL NOT ISSUE ANY FIRE WEATHER
WATCHES/WARNINGS ATTM.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...
NV...NONE.
AZ...NONE.
CA...HIGH WIND WATCH FROM LATE TONIGHT THROUGH MONDAY AFTERNOON FOR
     CAZ519-520.
