AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
250 AM PDT FRI MAR 25 2011

.SYNOPSIS...ANOTHER PACIFIC STORM SYSTEM WILL MOVE ACROSS THE
SOUTHERN SIERRA AND CENTRAL NEVADA THIS MORNING AND THEN EXIT TO THE
EAST BY THIS AFTERNOON. ADDITIONAL PACIFIC STORMS WILL MOVE INLAND
OVER THE WEEKEND BUT THE MAIN STORM TRACK IS MOVING TO THE NORTH
ACROSS NORTHERN CALIFORNIA AND NORTHERN NEVADA...LESSENING THE
CHANCE FOR PRECIPITATION...HOWEVER KEEPING LOCAL GUSTY WINDS IN THE
REGION.
&&

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT...AS OF 2 AM PDT THE CENTER
OF THE CURRENT STORM MOVING INTO AND ACROSS THE AREA IS JUST OFF THE
SOUTHERN OREGON COAST WITH A BAND OF MOISTURE PUSHING ACROSS THE
SOUTHERN SIERRA. THE WESTERN SLOPES OF THE SIERRA ARE INTERCEPTING
THE BULK OF THE MOISTURE BUT LIGHT TO MODERATE SNOW IS LIKELY OVER
THE EASTERN SLOPES THIS MORNING. AS THE SYSTEM SHIFTS EAST DURING
THE DAY...PRECIPITATION WILL BE INCREASING ACROSS SOUTHERN NEVADA
WITH THE SOUTH CENTRAL PORTION HAVING THE BEST CHANCE FOR MEASURE
PRECIPITATION. THIS SYSTEM WILL EXIT THE CWA LATE THIS AFTERNOON/
EARLY EVENING WITH A GENERALLY DRY WEST FLOW OVER THE REGION THEN
INTO SATURDAY MORNING. THE SERIES OF STORMS WHICH HAVE BEEN
IMPACTING THE REGION HOWEVER IS NOT OVER AS THE NEXT SYSTEM PUSHES
INTO NORTHERN CALIFORNIA BY EARLY SATURDAY MORNING. THIS STORM
GENERALLY TRACKS ACROSS NORTHERN CALIFORNIA/NORTHERN NEVADA DURING
THE DAY ON SATURDAY. YET ANOTHER SYSTEM PUSHES INTO THE PACIFIC
NORTHWEST LATE SUNDAY/SUNDAY NIGHT. THIS TRACK IS EVEN FURTHER NORTH
THAN SATURDAYS STORM WITH LITTLE IMPACT ON THE CWA. AS MENTIONED
AFTER TODAYS STORM...PRECIPITATION BECOMES LESS OF A CONCERN...
HOWEVER WINDS WILL CONTINUE TO BE A PROBLEM INTO THE WEEKEND. LOCAL
HIGH RESOLUTION MODELS INDICATE THAT GRADIENTS/FLOW ALOFT WILL BE
INCREASING ON SATURDAY AHEAD OF THE SYSTEM...ESPECIALLY OVER THE SAN
BERNARDINO COUNTY DESERTS WITH POSSIBLE WIND ADVISORIES NEEDED IN
LATER PACKAGES. HOWEVER THE BIGGEST CONCERN IS DOWNSLOPE WINDS
FORMING SATURDAY AFTERNOON/NIGHT OVER THE SOUTHERN SIERRA/OWENS
VALLEY/EAST SIDE OF THE WHITE MOUNTAINS AND WILL ISSUE A HIGH WIND
WATCH FOR THIS AREA WITH THIS PACKAGE. WITH THE STORM TRACK PUSHING
FURTHER NORTH...TEMPERATURES WILL BE WARMING THROUGH THE SHORT
TERM...WITH DAYTIME TEMPERATURES REACHING NEAR NORMAL READINGS BY
SUNDAY AFTERNOON.

.LONG TERM...MONDAY THROUGH THURSDAY...WEATHER PATTERN LOOKS TO BE
LESS AMPLIFIED THAN IT HAS BEEN FORECAST IN THE LAST FEW DAYS.
MONDAY WILL SEE A DEPARTING TROUGH EXITING THE AREA TO OUR
NORTHEAST. LEFT IN THE SLIGHT CHANCE POPS IN NORTHERN LINCOLN COUNTY
AND CLOUD COVER IN THE NORTH. TUESDAY WILL SEE A BRIEF TRANSIT SHORT
WAVE RIDGE OVER THE AREA BEFORE THE NEXT TROUGH COMES INTO PLAY
WEDNESDAY. THIS MIDWEEK TROUGH HAS BEEN WEAKENED AND TRACKED FURTHER
NORTH IN SUCCESSIVE MODEL RUNS THE LAST FEW DAYS TO THE POINT IT IS
LOOKING LESS LIKELY THERE WILL BE ANY PRECIPITATION IN THE FORECAST
AREA. STILL RETAINED THE SLIGHT CHANCE IN NORTHERN LINCOLN COUNTY
AND THE CLOUD COVER THERE. ONE QUESTION REMAINS ABOUT THIS SYSTEMS
WEAKENING TREND IS THE GEM AND GFS ENSEMBLE MEAN DO SHOW THIS TROUGH
AS DEEPER WHEN IT TRACKS THROUGH. DESPITE THIS WENT WITH THE GFS AND
ECMWF OPERATIONAL MODELS. ONE PARAMETER TO WATCH FOR IS THE WINDS
BEHIND THIS TROUGH AND ASSOCIATED FRONT. SLP GRADIENTS ARE FORECAST
TO TIGHTEN UP IN THE AREA BEHIND THE TROUGHS PASSAGE SO THERE EXISTS
THE POTENTIAL FOR BREEZY NORTH WINDS DOWN THE COLORADO RIVER VALLEY
WEDNESDAY AND THURSDAY. THURSDAY AND FRIDAY NEXT WEEK LOOK TO HAVE
RIDGING AND NORTHWEST FLOW OVER THE AREA TO BRING SLIGHTLY ABOVE
NORMAL TEMPERATURES AT WEEKS END.
&&

.AVIATION...FOR MCCARRAN...A TROUGH WILL BE PASSING THROUGH THE
REGION LATER THIS MORNING AND BRING WITH IT A SLIGHT CHANCE FOR RAIN
SHOWERS TO THE VALLEY AND GUSTY SOUTH WINDS. THOUGH CEILINGS WILL
NOT DROP MUCH BELOW 6K FEET WITH IT THE AREA MOUNTAINS WILL HAVE
MORE CLOUD COVER OBSCURING THE TOPS. THIS MORNING WILL ALSO SEE
STRONG GUSTY WINDS IN THE SPRING MOUNTAIN FOOTHILLS AND TURBULENCE
OVER THE MOUNTAINS. SKIES WILL SCATTER OUT THIS AFTERNOON AND WINDS
QUIT GUSTING AFTER SUNSET.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA....A TROUGH WILL BE PASSING THROUGH THE AREA THIS
MORNING AND AFTERNOON. IT WILL BRING RAIN OR SNOW TO AREA MOUNTAINS
PRIMARILY WITH A LESSOR LIKELIHOOD OF LOWER ELEVATION
PRECIPITATION.  GUSTY SOUTH TO SOUTHWEST WINDS WILL CONTINUE THROUGH
THE DAY TODAY AND SUBSIDE THIS EVENING.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...

AZ...NONE.
