AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1040 AM PST MON DEC 17 2007

.SYNOPSIS...MID AND HIGH LEVEL CLOUDS WILL INCREASE TODAY AND
TONIGHT AHEAD OF A FAST MOVING PACIFIC STORM WHICH WILL BRING A
CHANCE OF LIGHT RAIN AND SNOW TO MUCH OF THE REGION TUESDAY AND
TUESDAY NIGHT. ANOTHER PACIFIC SYSTEM IS FORECAST TO MOVE ACROSS THE
GREAT BASIN THURSDAY AND THURSDAY NIGHT.
&&

.UPDATE...MODELS GENERATING QUITE A BIT OF PRECIPITATION OVER THE
SIERRA FOR TUESDAY AND TUESDAY NIGHT. GIVEN THAT AND THE POTENTIAL
FOR SOME PRETTY STRONG WINDS...HAVE DECIDED TO ISSUE A WINTER STORM
WATCH.
&&

.PREV DISCUSSION...355 AM PST MON DEC 17...SHORT TERM...THE
PROGRESSIVE PATTERN IN PLACE WILL ALLOW FAST MOVING SHORTWAVES TO
SLIDE ACROSS THE REGION THROUGH THE WEEK FOR GENERALLY UNSETTLED
WEATHER BUT FAIRLY LOW IMPACT FOR MOST OF THE FORECAST AREA. THE 00Z
GFS AND ECMWF SOLUTIONS WERE PREFERRED AND BOTH WERE IN GOOD
AGREEMENT WITH THE OVERALL PATTERN THROUGH WEDNESDAY NIGHT. THE
LATEST NAM SOLUTIONS WERE NOT QUITE AS DEEP WITH THE INCOMING SYSTEM
TUESDAY. THE UPPER LEVEL SHORTWAVE MOVING ACROSS NORTHERN CALIFORNIA
AND NORTHWEST NEVADA THIS MORNING WILL QUICKLY LIFT NORTHEAST TODAY.
THE MAIN FOCUS OF THE FORECAST IS ON THE NEXT SYSTEM WHICH COULD BE
SEEN DIVING THROUGH THE SOUTHERN GULF OF ALASKA NEAR 45N/140W. IT
HAD ENTRAINED A SUBSTANTIAL SUBTROPICAL MOISTURE PLUME. THE TROUGH
AXIS IS FORECAST TO REACH CENTRAL CALIFORNIA TUESDAY AFTERNOON THEN
QUICKLY SLIDE ACROSS SOUTHERN NEVADA INTO NORTHERN ARIZONA/SOUTHERN
UTAH BY 12Z WEDNESDAY. MOST OF THE PRECIPITATION SHOULD BE
INTERCEPTED BY THE WESTERN SIERRA SLOPES BUT ENOUGH WILL ACCOMPANY
THE CORE OF THE SYSTEM FOR LIKELY PRECIP IN THE MOUNTAINS AND LOWER
CHANCES IN THE VALLEYS AND DESERTS. NEED TO KEEP AN EYE ON THE
POTENTIAL FOR HIGH WINDS ON THE EAST SLOPES OF THE SOUTHERN SIERRA
TUESDAY AFTERNOON AND EVENING...BUT MOISTURE AND STABILITY PROFILES
WERE WORKING AGAINST A SIGNIFICANT DOWNSLOPE WIND EVENT DOWN INTO
THE OWENS VALLEY. A BRIEF SHORTWAVE RIDGE IS INDUCED OVER THE REGION
WEDNESDAY AHEAD OF THE NEXT DEEPER TROUGH WHICH MOVES INLAND
THURSDAY. EVEN THOUGH THE FLOW IS FORECAST TO REMAIN FAIRLY MOIST
WEDNESDAY...LITTLE TO NO DYNAMIC SUPPORT IN THIS PATTERN SHOULD LEAD
TO VERY LITTLE CHANCE OF PRECIP FOR THE AREA WEDNESDAY.

.LONG TERM...UPPER TROUGH SHIFTING SOUTH INTO NORTHERN CALIFORNIA
WEDNESDAY NIGHT TO SHIFT ACROSS THE CWA THURSDAY AND THURSDAY NIGHT
WITH WEAK RIDGE THEN BUILDING OVER THE CWA FRIDAY INTO EARLY
SATURDAY. BOTH GFS/ECMWF IN FAIRLY GOOD AGREEMENT WITH THIS
SCENARIO...BUT THEN DIVERGE FROM THIS POINT ON. GFS ENSEMBLE ALSO
SHOWING VERY GOOD CONSISTENCY THROUGH 18Z SATURDAY. CONFIDENCE THEN
LOWERS FROM THIS POINT ON. ECMWF TRENDING TOWARDS A SERIES OF SHORT
WAVES DROPPING ACROSS THE CWA WITH ONE SATURDAY NIGHT/EARLY SUNDAY
AND THE NEXT LATE ON MONDAY. GFS TRENDS FLAT RIDGE THROUGH THE
WEEKEND WITH SHORT WAVE MOVING ACROSS NORTHERN AND CENTRAL NEVADA ON
MONDAY. FOR NOW WILL TREND TOWARDS CURRENT FORECAST WHICH SHOWS DRY
FOR SUNDAY WITH NEXT SHORT WAVE ON MONDAY PRODUCING A FEW SHOWERS
ACROSS THE NORTHERN PORTION OF THE CWA. LOOK FOR INCREASE IN WINDS
INTO FRIDAY AS SHORT WAVE EXITS TO THE EAST AND HIGH PRESSURE BUILDS
TO THE NORTH AND THEN MAY SEEN ADDITIONAL BREEZY CONDITIONS TOWARDS
THE END OF THE PERIOD. WILL CONTINUE TO TREND TEMPS BELOW MOS
GUIDANCE ESPECIALLY THURSDAY AND FRIDAY AS SHORT WAVE CROSSES OVER
THE AREA WITH NORTHERLY FLOW DEVELOPING BY THE END OF THE WEEK. &&

.AVIATION...FOR MCCARRAN...NO SIGNIFICANT WEATHER IS EXPECTED OVER
THE NEXT 24 HOURS WITH WINDS LESS THAN 10KTS AND VARIABLE HIGH LEVEL
CLOUDS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...GENERALLY LIGHT WINDS WITH VARIABLE HIGH LEVEL CLOUDS
THROUGH TODAY WITH INCREASED MOISTURE AND POSSIBLE SHOWERS EXPECTED
ACROSS THE SOUTHERN SIERRA TONIGHT AND EARLY TUESDAY MORNING...THEN
SPREADING ACROSS SOUTH CENTRAL/SOUTHERN NEVADA BY TUESDAY AFTERNOON.
ALSO LOOK FOR THE POSSIBILITY OF INCREASED WINDS PRODUCING MOUNTAIN
WAVES/DOWNSLOPE WINDS ACROSS THE OWENS VALLEY TUESDAY AFTERNOON.

.VEF WATCHES/WARNINGS/ADVISORIES...
NV...NONE.
AZ...NONE.
CA...WINTER STORM WATCH TUESDAY AND TUESDAY NIGHT ZONE 519.
