AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE LAS VEGAS NV
317 PM PST TUE DEC 26 2006

.SYNOPSIS...A PACIFIC STORM SYSTEM IS COMING ASHORE IN CALIFORNIA
TODAY AND WILL MOVE THROUGH THE REGION THE NEXT TWO DAYS. STARTING
TONIGHT HEAVY SNOW WILL BE POSSIBLE IN THE SIERRA OF CALIFORNIA AND
THEN THERE WILL BE A CHANCE OF LIGHT RAIN OR SNOW OVER MUCH OF THE
AREA WEDNESDAY. THE STORM SYSTEM WILL MOVE OUT OF THE ARE BY
LATE THURSDAY BRINGING COOLER TEMPERATURES AND STRONG NORTH WINDS
THURSDAY.
&&

.SHORT TERM...TROUGH SOMEWHAT SLOWER THAN PREVIOUSLY ANTICIPATED IS
MOVING SOUTHWARD INTO CALIFORNIA THIS AFTERNOON. FLOW IS MOIST
AHEAD OF IT AS IS EVIDENT IN WIDESPREAD RAINFALL IN NORTHERN
CALIFORNIA AND INTO NORTHERN NEVADA. TROUGH IS PROGGED TO MOVE SOUTH
INTO CALIFORNIA TONIGHT AND ACROSS NEVADA WEDNESDAY. SOME MOISTURE
WILL MAKE IT OVER THE MOUNTAINS INTO NEVADA AND BRING SOME
PRECIPITATION TO MAINLY HIGHER ELEVATIONS. PRECIPITATION WILL
BE DELAYED IN STARTING IN ALL AREAS AS MORNING SOUNDINGS SHOW DRY
AIR IN THE LOWER LEVELS THAT WILL NEED MOISTENING UP. MOISTURE PROGS
NOT AS MOIST AS YESTERDAY FOR THE SIERRA ZONE BUT THINK IT WISE TO
KEEP AS HIGHER MOISTURE VALUES TO SUPPORT HEAVY SNOW ARE NEAR THE
FORECAST AREA. JUST ISSUED A HIGH WIND WARNING FOR OUR SIERRA ZONE
AS WELL BASED ON A SPOTTER REPORT AT ASPENDELL (8500 FT) A WHILE
AGO. ALSO NOTED BISHOP AIRPORT IN VALLY GUSTING TO 45KT. IT APPEARS
THERE ARE BREAKING WAVES BRINGING THE WINDS.

BREEZY TO WINDY CONDITIONS WILL BE WIDE SPREAD WEDNESDAY AS WELL
WITH TIGHTENING GRADIENTS. NAM WAS TYPICALLY VERY STRONG IN THE WIND
FORECAST. IF IT VERIFIES THERE MAY BE NEED FOR SOME WIND ADVISORIES.
THURSDAY LOOKS EVEN BETTER FOR STRONG WINDS IN THE SOUTH PART OF THE
FORECAST AREA...ESPECIALLY THE COLORADO RIVER VALLEY...AS TROUGH
EXITS AND A STRONG (140+ MPH) NORTH TO SOUTH JET MOVES OVER THE CWA
WHILE HIGH PRESSURE RACES IN FROM THE NORTH. IT IS LIKELY WIND
ADVISORIES WILL BE NEEDED FOR THURSDAY.

.LONG TERM...GUSTY NORTH WINDS WILL PERSIST ON FRIDAY IN THE WAKE OF
THE DEPARTING STORM...ALTHOUGH NOT AS STRONG AS THURSDAY. AFTER
THAT...A DIRTY RIDGE IS EXPECTED TO DOMINATE THE SOUTHWESTERN STATES
INTO THE NEW YEAR WITH MOSTLY SUNNY TO PARTLY CLOUDY SKIES AND
LITTLE OR NO CHANCE OF PRECIP. TEMPERATURES WILL REBOUND TO SLIGHTLY
ABOVE NORMAL LEVELS BY NEW YEARS DAY...ESPECIALLY IN THE HIGHER
ELEVATIONS. DEEPER VALLEYS MAY BE AFFECTED BY TRAPPED COLD AIR WHICH
FAILS TO MIX OUT DURING THE SHORT DAYS WITH LOW SUN ANGLE.
&&

.AVIATION...TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER
CONDITIONS FOR AREA TERMINALS. SEE TAFS FOR KLAS...KVGT...KDRA...
