AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
942 AM PST SAT NOV 10 2012

.SYNOPSIS...SCATTERED SHOWERS WILL CONTINUE THROUGH THIS EVENING
MAINLY OVER THE HIGHER ELEVATIONS. HIGHS TODAY AND SUNDAY WILL BE 15
TO 20 DEGREES BELOW NORMAL. DRY WEATHER AND WARMING TEMPERATURES ARE
EXPECTED MONDAY THROUGH WEDNESDAY...THEN ANOTHER SYSTEM COULD IMPACT
THE AREA THURSDAY INTO FRIDAY WITH A FEW SHOWERS.
&&

.UPDATE...OVERALL THE CURRENT SHORT TERM FORECAST REMAINS PRETTY
MUCH ON TRACK HOWEVER HAVE UPDATED MAINLY MOHAVE COUNTY TO SHOW A
LITTLE LESS CHANCE AND AREAL COVERAGE OF SHOWERS FOR THIS AFTERNOON.
A WEAK RIPPLE MOVING THROUGH THE TROUGH CURRENTLY OVER THE CWA THIS
MORNING WILL HELP TO PROVIDE LIFT ACROSS THE REGION FOR THIS
AFTERNOON...BUT FOR MOHAVE COUNTY THE BEST CHANCE FOR SHOWERS SHOULD
BE NORTH OF KINGMAN. PER THE PREVIOUS DISCUSSION THE BEST CHANCE OF
SHOWERS ACROSS THE REMAINDER OF THE CFA WILL BE OVER THE
EASTERN/NORTHERN MOUNTAINS AND DUE TO THIS HAVE ALSO DECREASED POPS
SLIGHTLY IN THE KLAS VALLEY FOR THIS AFTERNOON. UPDATES OUT SHORTLY.

.PREV DISCUSSION...
215 AM PST SAT NOV 10 2012

.SHORT TERM...SATELLITE AND AREA RADARS SHOWED CLOUDS LIMITED TO
LINCOLN...NORTHERN MOHAVE AND FAR NORTHEAST CLARK COUNTIES EARLY
THIS MORNING...WITH MORE CLOUDS POISED TO ENTER INYO AND ESMERALDA
COUNTIES. IN BETWEEN WAS A LARGE CLEAR SLOT...WHICH WILL FILL IN
DURING THE DAY AS SUNSHINE AND VERY COLD AIR ALOFT LEAD TO
DESTABILIZATION. THE BEST PRECIP CHANCES SHOULD REMAIN MAINLY NORTH
AND EAST OF LAS VEGAS...WITH ONLY LIGHT AMOUNTS EXPECTED OVERALL
ALTHOUGH SOME OF THE MORE VIGOROUS SHOWERS /MORE LIKELY OVER THE
MOUNTAINS/ COULD DROP A QUICK ONE OR TWO INCHES OF SNOW. THE TROUGH
AXIS BEGINS TO MOVE EAST BY THIS AFTERNOON...WITH WARMER AIR ALOFT
MOVING IN THIS EVENING AND OVERNIGHT...STABILIZING THE AIRMASS AND
PUTTING AN END TO PRECIP CHANCES. GUSTY NORTH WINDS WILL DEVELOP
DOWN THE COLORADO RIVER TOMORROW AND ESPECIALLY MONDAY. WILL NEED TO
MONITOR FOR POSSIBLE LAKE WIND ADVISORIES...ALTHOUGH RIGHT NOW THE
MOST LIKELY OUTCOME APPEARS TO BE LOCALLY STRONG WINDS IN THE
LAUGHLIN/BULLHEAD CITY AND DAVIS DAM AREA. TEMPERATURES SUNDAY
MORNING WILL BE THE COLDEST OF THE PERIOD AT MOST
STATIONS...ALTHOUGH A FEW PLACES MAY GET THEIR COLDEST READINGS
MONDAY MORNING BEFORE THE WARMING TREND GETS UNDERWAY IN EARNEST ON
MONDAY. A FREEZE WATCH WAS ISSUED EARLIER FOR SOME OF THE OUTLYING
DESERT ZONES...AND THIS STILL LOOKS GOOD.

.LONG TERM...TUESDAY THROUGH SATURDAY...WEAK HIGH PRESSURE OVER THE
AREA TUESDAY WILL TRANSITION TO A MORE SOUTHWESTERLY FLOW WEDNESDAY
AS A PACIFIC TROUGH APPROACHES THE AREA. TEMPERATURES ON TUESDAY AND
WEDNESDAY ARE FORECAST TO RUN AT TO SLIGHTLY ABOVE NORMAL. MODELS
ARE IN SLIGHTLY BETTER AGREEMENT WITH THE TIMING OF THE MID WEEK
SYSTEM...BUT THE GFS IS STILL A LITTLE FASTER THEN BOTH THE GEM AND
ECMWF MODELS. STILL IT LOOKS LIKE ANOTHER ROUND OF BREEZY CONDITIONS
THURSDAY AS THIS SYSTEM APPROACHES THE AREA. ALTHOUGH THIS SYSTEM
MOVING INTO THE REGION THURSDAY AND FRIDAY DOES NOT APPEAR TO BE AS
STRONG AND COLD AS THE CURRENT SYSTEM AFFECTING THE AREA...IT IS
TAKING A LITTLE FURTHER SOUTHERLY TRACK. THIS HAS THE POTENTIAL OF
PULLING UP MORE MOISTURE AND BRINGING MORE PRECIPITATION TO THE
REGION. IT DOES NOT LOOK TO BE A MAJOR STORM...BUT IT COULD PRODUCE
A FEW INCHES OF SNOW FOR THE HIGHER ELEVATIONS AND SCATTERED SHOWERS
FOR THE VALLEYS. DID INCREASE POPS OVER MUCH OF THE AREA THURSDAY
AND THURSDAY NIGHT. SYSTEM LOOKS TO QUICKLY EXIT THE AREA FRIDAY
WITH A FEW LINGERING SHOWERS STILL POSSIBLE OVER THE EASTERN
PORTIONS OF THE AREA. DRY CONDITION LOOK TO RETURN SATURDAY AS WEAK
HIGH PRESSURE BRIEFLY BUILDS IN.

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS UNDER 8KTS EXPECTED
THROUGH MIDDAY WITH WINDS TURNING MORE TOWARD THE WEST NORTHWEST
DURING THE AFTERNOON AND EVENING. WIND SPEEDS ARE STILL EXPECTED TO
REMAIN UNDER 8KTS. SKIES ARE LIKELY TO START OUT GENERALLY
CLEAR...BUT CLOUDS WILL QUICKLY DEVELOP DURING THE MORNING HOURS
WITH BASES DOWN TO 5-7K FEET AT TIMES THROUGH THE AFTERNOON. SHOWER
ACTIVITY SHOULD BE CONFINED TO THE MOUNTAINS SURROUNDING THE VALLEY
THIS AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...WINDS HAVE WEAKENED OVER MUCH OF THE REGION WITH MOST
WIND SPEEDS UNDER 12KTS. GUSTY WINDS ARE STILL LIKELY TO OCCUR
THROUGHOUT THE SOUTHERN AND WESTERN PORTIONS OF SAN BERNARDINO
COUNTY ALONG WITH SOUTHERN MOHAVE COUNTY. WINDS IN THOSE LOCATIONS
WILL BE SOUTHWEST TO WEST AROUND 15-25KTS WITH GUSTS TO 30KTS AT
TIMES. A FEW LIGHT SHOWERS THIS MORNING OVER LINCOLN COUNTY WITH
GENERALLY CLEAR SKIES ELSEWHERE. HOWEVER CLOUDS WILL QUICKLY DEVELOP
DURING THE MORNING HOURS WITH SCATTERED SHOWERS OCCURRING OVER THE
HIGHER TERRAIN THROUGH THE AFTERNOON. CIGS DOWN TO 5-7K FEET AT
TIMES.
