AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
955 AM PST MON DEC 17 2012

.SYNOPSIS...THE REGION WILL BE UNDER A WESTERLY FLOW TODAY WITH ANY
PRECIPITATION STAYING MAINLY TO THE NORTH. A STRONG LOW PRESSURE
SYSTEM WILL BRING A GOOD CHANCE OF RAIN AND SNOW TONIGHT THROUGH
TUESDAY EVENING ALONG WITH AREAS OF GUSTY WINDS. TEMPERATURES WILL
REMAIN SLIGHTLY BELOW NORMAL THROUGH TUESDAY WITH EVEN COOLER
TEMPERATURES WEDNESDAY AND THURSDAY BEHIND THE STORM.
&&

.UPDATE...EXTENSIVE STRATUS LAYER ENCOMPASSING MUCH OF SOUTHERN
NEVADA AND NORTHWEST ARIZONA THIS MORNING. LAYER ERODING AWAY SOME
OVER SOUTHERN CLARK COUNTY WITH POCKETS OF MORE BLUE SKY EVIDENT
AROUND THE LAS VEGAS VALLEY. STRATUS LAYER LOW ENOUGH THAT IF YOU
HEAD INTO THE SPRING MOUNTAINS AND SHEEP RANGE YOU WILL BE BASKING
UNDER MOSTLY SUNNY SKIES. DO NOT BELIEVE THERE WILL BE MUCH EROSION
OF THE LAYER IN LINCOLN...NORTHEAST CLARK AND NORTHERN MOHAVE
COUNTIES. WILL UPDATE TO INCREASE SKY GRIDS THE REST OF THE DAY IN
THOSE PARTICULAR COUNTIES.

STRONG PROGRESSIVE TROUGH ON TUESDAY STILL EXPECTED TO IMPACT
NORTHERN LINCOLN COUNTY WITH A BAND OF HEAVY SNOW WHILE STRONG WEST
WINDS DEVELOP ACROSS THE HIGH DESERT OF SAN BERNARDINO COUNTY. WILL
NEED TO CONSIDER UPGRADING WINTER STORM WATCH FOR LINCOLN COUNTY AS
WELL AS ANY ADDITIONAL WIND PRODUCTS WITH THE AFTERNOON PACKAGE.
UPDATES OUT SHORTLY.
&&

.AVIATION...FOR MCCARRAN...LIGHT AND VARIABLE DURING MUCH OF THE DAY
TODAY...BECOMING SOUTHWEST GENERALLY LESS THAN 10 KTS EARLY THIS
EVENING. LOW LEVEL MOISTURE ACROSS MUCH OF THE AREA WILL KEEP LOW
CLOUDS AROUND FOR MUCH OF THE DAY. CIGS AROUND 4-5K FEET ARE
EXPECTED THROUGH MID AFTERNOON...BECOMING SCATTERED BRIEFLY BEFORE
LOWERING ONCE AGAIN THIS EVENING WITH CIGS 3-4K FEET. SOUTHWEST
WINDS WILL INCREASE TUESDAY MORNING AS THE NEXT SYSTEM
APPROACHES THE AREA. THIS SYSTEM IS EXPECTED TO BRING GUSTY
WINDS...LOWERED CIGS...AND PRECIPITATION TUESDAY AFTERNOON AND
EVENING...WITH THE MOST PROBABLE PERIOD FOR IMPACTS BETWEEN 21Z
TUESDAY AND 06Z WEDNESDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...LIGHT WINDS FAVORING TYPICAL DIURNAL TRENDS WILL
CONTINUE THIS AFTERNOON. A LARGE SWATH OF LOW LEVEL MOISTURE REMAINS
IN PLACE ACROSS THE CENTRAL PART OF THE FORECAST AREA. WITHIN THIS
SWATH...BKN-OVC CIGS OF 3-7K FT WILL LIKELY CONTINUE THROUGH MUCH OF
THE DAY...GRADUALLY BECOMING SCT-BKN BY MID AFTERNOON. THE WESTERN
LOCATIONS LIKE KDAG AND KBIH WILL HAVE MOSTLY SUNNY SKIES THIS
AFTERNOON. CONTINUED LIGHT WINDS ARE EXPECTED AT MOST LOCATIONS
THROUGH THIS AFTERNOON...BEFORE THE NEXT MAJOR SYSTEM IMPACTS THE
REGION ON TUESDAY. SOUTHWEST WINDS WILL BEGIN TO INCREASE AND BECOME
GUSTY ACROSS EASTERN SAN BERNARDINO COUNTY MONDAY NIGHT AND ACROSS
THE REST OF THE AREA ON TUESDAY. THE NEXT SYSTEM IS EXPECTED TO
BRING GUSTY WINDS ACROSS MUCH OF THE REGION AS WELL AS LOWERED CIGS
AND PRECIPITATION TO AT LEAST SOUTHERN NEVADA AND NORTHWEST ARIZONA
TUESDAY THROUGH TUESDAY NIGHT.

.PREV DISCUSSION...
245 AM PST MON DEC 17 2012

.SHORT TERM...SATELLITE IMAGERY AND SURFACE OBSERVATIONS INDICATED
AN EXTENSIVE AREA OF LOW/MID CLOUDS OVER THE AREA AND IT LOOKS LIKE
THOSE WILL LINGER MUCH OF THE MORNING AND TO SOME EXTENT INTO THE
AFTERNOON. MUCH OF THE AREA WILL SEE MOSTLY CLOUDY SKIES FOR A GOOD
PORTION OF TODAY DESPITE THE WESTERLY FLOW WE ARE UNDER. WITH NO
DYNAMICS/FORCING TO SPEAK OF...NO PRECIPITATION IS EXPECTED TODAY
WITH THE EXCEPTION OF SOME LIGHT SPILL OVER INTO THE HIGHER
ELEVATIONS OF THE SIERRA. WITH THE MODERATELY STRONG WESTERLY
FLOW...WINDY CONDITIONS ARE EXPECTED IN THE SIERRA BUT THOSE STRONG
WINDS ARE NOT EXPECTED TO REACH DOWN TO THE LOWER SLOPES OR INTO THE
OWENS VALLEY. MOISTURE WILL INCREASE TONIGHT AS A TROUGH APPROACHES
THE CALIFORNIA COAST WITH RAIN AND SNOW CHANCES DEVELOPING ACROSS
ROUGHLY THE NORTHERN HALF OF THE FORECAST AREA. PRECIPITATION
AMOUNTS WILL REMAIN FAIRLY LIGHT TONIGHT. THE TROUGH THEN SWINGS
INTO CALIFORNIA AND WESTERN NEVADA TUESDAY WHILE DEEPENING...LEADING
TO AT LEAST A CHANCE OF RAIN AND SNOW FOR THE ENTIRE FORECAST AREA.
MODELS REMAIN CONSISTENT DEVELOPING A BAND OF MODERATE PRECIPITATION
ACROSS LINCOLN COUNTY INTO CENTRAL NYE COUNTY AND NO CHANGES WERE
MADE TO THE WINTER STORM WATCH FOR LINCOLN COUNTY TUESDAY. SOUTH OF
THE MAIN PRECIPITATION BAND TUESDAY...GUSTY WINDS ARE EXPECTED
ACROSS PORTIONS OF THE MOJAVE DESERT. A WIND ADVISORY WILL LIKELY BE
NEEDED FOR AT LEAST THE NORTHWEST PORTION OF SAN BERNARDINO COUNTY.
THE TROUGH AXIS THEN SHIFTS FAIRLY QUICKLY EAST INTO CENTRAL UTAH
AND ARIZONA TUESDAY NIGHT WITH PRECIPITATION ENDING FROM WEST TO
EAST. SOME DECENT PRECIPITATION AMOUNTS ARE POSSIBLE IN MOHAVE
COUNTY TUESDAY EVENING BEFORE THE TROUGH MOVES EAST.

.LONG TERM...WEDNESDAY THROUGH MONDAY...AN AREA OF COLD HIGH
PRESSURE WILL SET UP UNDER AN UPPER LEVEL RIDGE OVER THE WESTERN
CONUS IN THE WAKE OF TUESDAYS SYSTEM. THIS WILL SET THE STAGE FOR A
PERIOD OF COOL...DRY...AND BREEZY CONDITIONS ACROSS THE FORECAST
AREA. BRISK NORTH WINDS AND CLEARING SKIES ARE EXPECTED TO DOMINATE
WEDNESDAY...MAKING CONDITIONS FEEL EVEN COLDER. THE STRONGEST WINDS
ARE EXPECTED TO DEVELOP ALONG THE COLORADO RIVER VALLEY.

WINDS WILL TAPER OFF WEDNESDAY NIGHT WHICH WILL COMBINE WITH THE
CONSIDERABLY COOLER AIRMASS AND MOSTLY CLEAR SKIES TO BRING VERY
CHILLY THURSDAY MORNING LOWS. IT MAY EVEN BRING THE FIRST FREEZING
TEMPERATURES SEEN IN PORTIONS OF THE LAS VEGAS VALLEY IN OVER A
YEAR...BREAKING THE ONGOING RECORD FREEZE-LESS STREAK. WITH GUIDANCE
CONTINUING TO TREND COOLER...HAVE KNOCKED THE LOW AT MCCARRAN DOWN
TO 32 DEGREES THURSDAY MORNING.

UPPER LEVEL FLOW WILL BEGIN TO BACK THURSDAY AS THE RIDGE AXIS MOVES
EAST OF THE FORECAST AREA. MEDIUM RANGE GUIDANCE REMAINS IN FAIRLY
GOOD AGREEMENT THAT AN UPPER LEVEL LOW WILL BECOME CUT OFF IN THE
VICINITY OF 130W-135W IN THE GULF OF ALASKA AND BEGIN TO MEANDER
SOUTH THROUGH AT LEAST FRIDAY NIGHT. THIS SOUTHWARD MOVEMENT IS ALSO
EXPECTED TO PUSH A STREAM OF MOISTURE SOUTH...BRINGING A SLIGHT
CHANCE OF PRECIPITATION TO THE SIERRA OF INYO COUNTY BY FRIDAY.

CONFIDENCE BEGINS TO WANE THEREAFTER AS MODELS DIVERGE ON HOW THE
LOW IS HANDLED. THE ECMWF AND GEM ARE THE DEEPEST WITH THE SYSTEM
WHILE THE GFS...GFS ENSEMBLE MEAN...AND DGEX ARE MUCH
SLOWER/SHALLOWER THROUGH THE WEEKEND. I PREFERRED THE DEEPER
SOLUTION...WITH A NUDGE TOWARD THE GEM DUE TO ITS SLOWER TIMING
WHICH MAKES SENSE WITH A DOWNSTREAM BLOCKING PATTERN DEVELOPING OVER
FAR EASTERN CANADA. OVERALL...THE CHANCES FOR PRECIPITATION BEGIN TO
INCREASE AREAWIDE BY SUNDAY/SUNDAY NIGHT AS THE LOW MOVES ONSHORE.
IF THE GFS/DGEX SOLUTION COMES TO FRUITION...PRECIPITATION CHANCES
MAY BE HELD OFF UNTIL EARLY NEXT WEEK.
