AREA FORECAST DISCUSSION UPDATE
NATIONAL WEATHER SERVICE LAS VEGAS NV
938 AM PST WED FEB 22 2012

.SYNOPSIS...DRY CONDITIONS AND WARMING TEMPERATURES WILL CONTINUE
THROUGH THE WORK WEEK. A STRONGER STORM SYSTEM IS EXPECTED NEXT
WEEKEND WHICH COULD RESULT IN A PERIOD OF STRONGER WINDS AND COOLER
TEMPERATURES.
&&

.UPDATE...FORECAST RIGHT ON TRACK AS SURFACE TEMPERATURES ARE NEARLY
8 DEGREES WARMER THAN THIS TIME YESTERDAY. NO MAJOR UPDATES WILL BE
NEEDED...BUT WILL MODIFY GRIDS SLIGHTLY TO ACCOUNT FOR INCREASED
CIRRUS ACROSS THE REGION. -KENNEDY-
&&

.PREV DISCUSSION...
233 AM PST WED FEB 22 2012

.SHORT TERM...TODAY THROUGH SATURDAY MORNING.
NO CHANGES PLANNED TO THE CURRENT FORECAST. THERE IS A RIDGE OF
HIGH PRESSURE IN THE EASTERN PACIFIC AND A CUT OFF LOW CONTINUES
TO SPIN OFF OF THE BAJA COAST. THIS WILL RESULT IN MOSTLY SUNNY TO
PARTLY CLOUDY SKIES FOR THE NEXT SEVERAL DAYS. GUSTY NORTH WINDS
CONTINUE TO BE THE ONLY REAL CONCERN...ESPECIALLY ALONG THE
COLORADO RIVER VALLEY. EXPECT WIND GUSTS TODAY OF 25 TO 30 MPH AND
A BIT STRONGER TOMORROW. AT THIS TIME EXPECT WINDS TO STAY BELOW
LAKE WIND CRITERIA BUT WILL CONTINUE TO KEEP AN EYE ON THIS. THE
PRESSURE GRADIENT RELAXES ON FRIDAY AS THE CUT OFF LOW MOVES EAST
AND THE NEXT SYSTEM MOVES TOWARD THE PACIFIC NORTHWEST COAST.

TEMPERATURES WILL WARM ANOTHER 5-7 DEGREES TODAY FROM YESTERDAY
AND BE ABOUT THE SAME TOMORROW. AFTERNOON TEMPERATURES WILL THEN
COOL ON FRIDAY BACK TOWARDS NORMAL.

.LONG TERM...MODELS ARE IN SLIGHTLY BETTER AGREEMENT ABOUT THE
SHORTWAVE TROUGH THAT WILL MOVE THROUGH THE REGION SATURDAY. THEY DO
AGREE THAT THIS SYSTEM WILL BE MORE OF A GLANCING BLOW WITH THE
BETTER PRECIPITATION CHANCES REMAINING OVER THE NORTHEAST AREAS OF
THE CWA. WILL STILL NEED TO WATCH FOR THE POTENTIAL OF GUSTY
SOUTHWEST TO WEST WINDS SATURDAY AFTERNOON AS BOTH SURFACE PRESSURE
AND THERMAL GRADIENTS ARE FAIRLY TIGHT. THERE WILL ALSO BE UPPER
LEVEL SUPPORT FROM A 100+KT JET STREAK. WOULD NOT BE SURPRISED IF
WIND ADVISORIES WILL BE NEEDED AS THE WEEKEND APPROACHES.
TEMPERATURES WILL WARM TO A FEW DEGREES ABOVE NORMAL SATURDAY...BUT
FALL ABOUT 10 DEGREES ON SUNDAY AS COLDER AIR FILTERS INTO THE AREA
BEHIND THE TROUGH. THE GFS/GEM/GFS ENSEMBLES SHOWING ANOTHER TROUGH
DIGGING INTO THE AREA TUESDAY REINFORCING THE COOLER AIR AND
BRINGING ANOTHER SLIGHT CHANCE OF SHOWERS TO THE NORTHERN AREAS OF
THE CWA. PRECIPITATION CHANCES AGAIN LOOK MARGINAL AND MAINLY WILL
AFFECT THE NORTHEAST AREAS. WEAK RIDGING WEDNESDAY WITH ANOTHER WEAK
SYSTEM MOVING THROUGH THE REGION LATE IN THE WEEK. THIS SYSTEM LOOKS
TO TAKE THE SAME PATH AS THE PREVIOUS SYSTEMS AND WILL BRING MAINLY
WIND CONCERNS ALONG WITH COOLER TEMPERATURES.

.AVIATION...FOR MCCARRAN...SOUTH TO  SOUTHWEST WINDS THROUGH EARLY
THIS MORNING UP TO 8KTS. LIGHT AND VARIABLE WINDS THROUGH THIS
AFTERNOON WITH OCCASIONAL HIGH LEVEL CLOUDS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS WILL CONTINUE BE LIGHT AREA WIDE THROUGH TODAY
AND FOLLOW LOCAL FAIR WEATHER DIURNAL PATTERNS. THE EXCEPTION WILL
BE THE LOWER COLORADO RIVER VALLEY WHERE LATE MORNING THROUGH LATE
AFTERNOON NORTH WINDS WILL GUST TO AROUND 20 KNOTS. SCATTERED TO
BROKEN HIGH LEVEL CIRRUS CLOUDS WILL BE MOVING THROUGH THE AREA.
