AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1003 AM PDT MON MAR 18 2013

.SYNOPSIS...A CONSIDERABLE AMOUNT OF HIGH CLOUDINESS IS EXPECTED
THROUGH TUESDAY AHEAD OF AN AREA OF LOW PRESSURE APPROACHING THE
WEST COAST. THIS PACIFIC STORM WILL MOVE THROUGH THE AREA ON
WEDNESDAY AND WEDNESDAY NIGHT PRODUCING GUSTY WINDS ACROSS THE
MOJAVE DESERT AND LIGHT SHOWERS MAINLY OVER THE MOUNTAINS OF THE
SOUTHERN GREAT BASIN. EVEN WITH THE ARRIVAL OF THE STORM...ABOVE
NORMAL TEMPERATURES WILL CONTINUE DURING THE PERIOD.
&&

.UPDATE...AREA LYING IN A BREAK BETWEEN HIGH CLOUDS WITH SATELLITE
SHOWING NEXT AREA LURKING OFF THE CENTRAL CALIFORNIA COAST. TIME
HEIGHTS SIMILAR TO YESTERDAY SHOWING A CONSIDERABLE AMOUNT OF H7-H3
MOISTURE THROUGH WEDNESDAY EVENING. 12Z HI RES NMM-4KM INDICATES
GREATER POTENTIAL OF DOWNSLOPE WINDS IN THE LEE OF THE SRN
SIERRA/OWENS VALLEY WEDNESDAY AFTERNOON AND EVENING. NO UPDATE
NECESSARY THIS MORNING. WILL BE CONTEMPLATING THE NEED FOR A HIGH
WIND WATCH WEDNESDAY WITH THE AFTERNOON PACKAGE.
&&

.AVIATION...FOR MCCARRAN...NORTHEAST TO EASTERLY WINDS GENERALLY
LESS THAN 10KTS THROUGH TODAY...BECOMING SOUTHWEST AFTER 03Z
TUESDAY. CLOUDS AOA 25K FT THROUGH 06Z TUESDAY...LOWERING TO SCT-BKN
12K FEET BETWEEN 10-15Z TUESDAY...THEN CLEARING. NO SIGNIFICANT
WEATHER IS EXPECTED THROUGH THE PERIOD.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS FAVORING A NORTHERLY DIRECTION THIS AFTERNOON. A
FEW GUSTS OF 15-25 KTS WILL BE POSSIBLE ALONG THE COLORADO RIVER
VALLEY NEAR KIFP...ELSEWHERE WINDS SHOULD REMAIN GENERALLY LESS THAN
12 KTS. DIURNAL WINDS ARE EXPECTED ONCE AGAIN THIS EVENING AND
OVERNIGHT...WITH THE STRONGEST WINDS AROUND 15 KTS NEAR KDAG.
OCCASIONAL CLOUDS AOA 20K FEET WILL DRIFT ACROSS THE REGION AT
TIMES. CIGS MAY LOWER TO AROUND 10-15K FEET BY TUESDAY MORNING.
LOOKING TO THIS WEEK...MUCH STRONGER WEST/SOUTHWEST WINDS ARE
ANTICIPATED ACROSS AT LEAST THE SOUTHERN HALF OF THE FORECAST AREA
WEDNESDAY THROUGH THURSDAY MORNING.
&&

.PREV DISCUSSION...
256 AM PDT MON MAR 18 2013

.SHORT TERM...NORTHWEST FLOW WILL BE OVER THE AREA TODAY WITH A
RIDGE OF HIGH PRESSURE OFF THE COAST. THE RIDGE WILL TRAVERSE THE
REGION TUESDAY AND TUESDAY NIGHT. THIS PATTERN WILL LEAD TO
CONTINUED DRY CONDITIONS WITH TEMPERATURES ABOVE NORMAL. QUITE A BIT
OF HIGH LEVEL MOISTURE APPEARS TO BE CAUGHT UP IN THE FLOW AND
CONSIDERABLE HIGH CLOUD COVER IS EXPECTED AT TIMES THROUGH TUESDAY
NIGHT. BY WEDNESDAY...A LOW DROPPING OUT OF THE GULF OF ALASKA WILL
PHASE WITH A SOUTHERN SYSTEM AND MOVE INLAND WEDNESDAY AFTERNOON AND
INTO NEVADA WEDNESDAY NIGHT. THE BEST UPWARD FORCING AND MOISTURE
WITH THIS SYSTEM WILL MAINLY BE NORTH OF THE AREA BUT THERE MAY BE A
FEW LIGHT SHOWERS WEDNESDAY AND WEDNESDAY NIGHT...MAINLY OVER THE
MOUNTAINS OF THE SOUTHERN GREAT BASIN. CLEARING WILL BEGIN TO TAKE
PLACE IN THE WESTERN PART OF THE FORECAST AREA LATER WEDNESDAY NIGHT
AS THE TROUGH AXIS APPROACHES THE UTAH BORDER. THE MORE SIGNIFICANT
IMPACT WITH THIS SYSTEM WILL BE WINDS. SAN BERNARDINO COUNTY WILL
LIKELY SEE WESTERLY WINDS GUSTING BETWEEN 40 AND 50 MPH. A BAND OF
GUSTY SOUTHWEST WINDS WILL STRETCH ACROSS CLARK AND MOHAVE COUNTIES
WITH GUSTS IN THE 35 TO 45 MPH RANGE. THE LATEST ARW 9KM INDICATES
POTENTIAL FOR MODERATELY STRONG DOWNSLOPE WINDS ALONG THE EASTERN
SIERRA SLOPES AND EXTENDING DOWN INTO THE OWENS VALLEY...AT LEAST IN
THE INDEPENDENCE AREA. THIS MODEL HAS BEEN KIND OF INCONSISTENT WITH
THE DEVELOPMENT OF THESE DOWNSLOPE WINDS SO CONFIDENCE IS LOW.

.LONG TERM...THURSDAY THROUGH SUNDAY...SPLIT ENERGY FROM WEDNESDAYS
SYSTEM WILL BE MOVING SOUTH AND EAST OF THE FORECAST AREA BY
THURSDAY MORNING. WEST WINDS WILL BE DECREASING ACROSS SAN
BERNARDINO COUNTY AS A STRONG PUSH OF NORTHERLY WINDS FOLLOWS A COLD
FRONT ACROSS THE FORECAST AREA. AT THIS TIME THESE NORTH WINDS
APPEAR TO BE JUST SHY OF THE WIND ADVISORY CRITERIA OF 40 KT
GUSTS...BUT WILL HAVE TO CONTINUE TO MONITOR THIS POTENTIAL. THE
STRENGTH OF THESE WIND SHOULD BEGIN TO DECREASE BY EARLY THURSDAY
AFTERNOON...BUT BREEZY CONDITIONS WILL LIKELY BE SEEN AREAWIDE INTO
THE EVENING HOURS.

FRIDAY THROUGH SUNDAY WILL SEE THE BACK EDGE OF A TROUGH OF LOW
PRESSURE JUST TO THE EAST OF THE AREA. THIS WILL LEAVE THE DOOR OPEN
FOR ADDITIONAL SHORTWAVES TO MOVE DOWN THE BACKSIDE AND BRING
PERIODS OF GUSTY WINDS TO THE REGION. MODELS ARE NOTORIOUSLY BAD AT
ACCURATELY RESOLVING THESE FEATURES THIS FAR OUT...THUS HAVE
BROAD-BRUSHED NORTH WINDS ACROSS THE REGION THROUGH THE WEEKEND. ONE
CAN EXPECT PERIODS OF GUSTY WINDS DOWN THE COLORADO RIVER VALLEY
INCLUDING THE LAKES THIS COMING WEEKEND. TEMPERATURES WILL ALSO BE
DEPENDENT ON THE DISTURBANCES MOVING THROUGH THE FLOW...FOR NOW HAVE
INCLUDED TEMPERATURES NEAR OR SLIGHT ABOVE NORMAL THIS WEEKEND...BUT
CONFIDENCE IS LOW IN EXACT NUMBERS. IT APPEARS THAT MAYBE BY LATE
SUNDAY OR MONDAY THE TROUGH WILL BEGIN TO PUSH EAST AND BROAD
RIDGING WILL BEGIN TO TAKE OVER THE WESTERN CONUS...LEADING TO A
NICE WARMING TREND.
