AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
830 AM PST THU DEC 1 2011
.SYNOPSIS...A POWERFUL STORM SYSTEM CENTERED BETWEEN LAS VEGAS AND
YUMA TODAY AND TONIGHT WILL PULL AWAY TO THE EAST ON FRIDAY. THIS
WILL PRODUCE STRONG NORTH WINDS THROUGH THIS EVENING. IN
ADDITION...PRECIPITATION WILL OCCUR THROUGH FRIDAY MORNING ACROSS
SOUTHEAST NEVADA...EASTERN CALIFORNIA AND NORTHWEST ARIZONA WITH
SIGNIFICANT SNOW ACCUMULATIONS ABOVE 4000 FEET. ANOTHER STORM WILL
DROP INTO SOUTHERN NEVADA SATURDAY AND SUNDAY AND BRING A
REINFORCING SHOT OF COLD AIR AND A CHANCE OF RAIN AND SNOW PRIMARILY
TO NORTHWEST ARIZONA.
&&
.UPDATE...DECEMBER IS DEBUTING ON A COLD...WINDY AND WET (OR SNOWY)
TONE ACROSS THE AREA THANKS TO AN UPPER LEVEL LOW THAT IS CRANKING
UP ACROSS SOUTHEAST CALIFORNIA. OVERALL AT THIS TIME THE FORECAST IS
NOT IN BAD SHAPE. THE ONLY ADJUSTMENTS I MADE WERE ACROSS CLARK
COUNTY WHERE NORTHEAST FLOW WAS CREATING SOMEWHAT OF A COLD AIR
DAMMING SITUATION AND HOLDING TEMPS DOWN ON THE SOUTH AND WEST ENDS
OF THE LAS VEGAS VALLEY AND IN SOUTHERN CLARK COUNTY. TEMPS MAY
STRUGGLE TO RISE IN THESE AREAS. I DECIDED TO LOWER HIGHS TODAY IN
THESE AREAS. MEANWHILE OVER THE NORTH SIDE OF THE LAS VEGAS VALLEY
DOWNSLOPING OFF THE SHEEP RANGE WAS KEEPING TEMPS MUCH WARMER WITH
TEMPS IN THE UPPER 40S. THE FLOW OFF THE SHEEP WAS ALSO DRYING OUT
THINGS OVER THE NORTH SIDE OF THE VALLEY WITH NO RAIN FALLING THERE.
MOUNTAIN WAVE ACTIVITY OFF THE SHEEP WAS EVIDENT BY THE LENTICULARS
THAT DEVELOPED TO THE LEE OF GASS PEAK THIS MORNING...A VERY RARE
SCENARIO. OVER THE SOUTH END AND WEST OF THE VALLEY WE HAVE HAD A
FEW REPORTS OF RAIN AND SNOW MIXED IN ANTHEM AND SUMMERLIN AND A
LOOK OUTSIDE OF OUR OFFICE SHOWS THE BLACK MOUNTAINS WHITENED PRETTY
GOOD. A RAIN/SNOW MIX ALSO TOOK PLACE IN JEAN WHILE SEARCHLIGHT
REPORTED A LIGHT COATING OF SNOW. I HAVE ISSUED A SPECIAL WEATHER
STATEMENT TO HIGHLIGHT THE LOW SNOW LEVELS IN CLARK COUNTY TODAY. AS
THE MAIN BAND OF PRECIP SETS UP THIS AFTERNOON...THE LATEST TRENDS
FROM THE GFS/ECMWF AND WRF INDICATE IT MAY SET UP OVER SOUTHERN
CLARK COUNTY. SO THE COLD NORTHEAST FLOW MAY KEEP TEMPS DOWN HERE
AND CREATE A BETTER POTENTIAL FOR SNOW. I MADE SOME ADJUSTMENTS TO
SNOW LEVELS AND QPF FOR THIS AFTERNOON AND EVENING TO REFLECT THESE
TRENDS.
&&
.PREVIOUS DISCUSSION...
ISSUED 457 AM PST THU DEC 1 2011
.SHORT TERM...RECENT SATELLITE AND RADAR LOOPS SHOWED THE CLOSED LOW
CENTER BECOMING MORE DEFINED NEAR THE TIP OF SOUTHERN NEVADA. THE
SURFACE PRESSURE GRADIENT BETWEEN RENO AND LAS VEGAS WAS STILL OFF
THE CHARTS AT 22 MB. THE INCREASING NORTHEAST WIND TREND AT 700MB
ON THE MODELS BETWEEN 06Z AND 12Z APPEARED TO BE MATERIALIZING AS
BOTH THE DESERT NWR AND KANE SPRINGS SENSORS IN THE SHEEP RANGE AND
SOUTHERN LINCOLN COUNTY WERE RECORDING SIGNIFICANT JUMPS WITH GUSTS
OF 74 MPH AND 87 MPH RESPECTIVELY. THE 00Z GFS...NAM AND ECMWF WERE
ALL NOW IN GOOD WITH THE OVERALL POSITION AND FEATURES WITH THE
SYSTEM AND SHOWED THE CENTER SETTING UP ROUGHLY OVER LAKE HAVASU BY
18Z AND REMAINING THERE THROUGH EARLY FRIDAY MORNING BEFORE SLOWLY
PULLING EAST. OVERALL THE INHERITED FORECAST TRENDS WERE IN GOOD
AGREEMENT WITH THE LATEST OBSERVATIONS AND MODEL GUIDANCE. THE MAIN
CHANGES TO THE FORECAST WERE TO ADD A WINTER WEATHER ADVISORY FOR
SNOW AND BLOWING SNOW TO EASTERN SAN BERNARDINO COUNTY...PRIMARILY
FOR THE MOJAVE NATIONAL PRESERVE AND MOUNTAIN PASS ON I-15. THE 06Z
GFS CONTINUED TO INDICATE A BAND OF PRECIPITATION BECOMING
ESTABLISHED ACROSS CENTRAL MOHAVE COUNTY AND EXTENDING ACROSS MOST
OF CLARK AND EASTERN SAN BERNARDINO COUNTIES BETWEEN 18Z AND 00Z
TODAY THEN SHIFT SOUTHWARD TONIGHT. IT SHOULD STILL REMAIN OVER
SOUTHERN CLARK COUNTY AND THE MOJAVE NATIONAL PRESERVE/MOUNTAIN PASS
AREA TONIGHT. PRECIPITATION IS FORECAST TO DIMINISH BETWEEN 12Z AND
18Z FRIDAY AS THE LOW BEGINS TO OPEN UP AND PULL EAST. ALSO...WILL
HAVE TO INCREASE TOTAL SNOW ACCUMULATIONS BASED ON LATEST REPORTS
OUT OF THE SPRING MOUNTAINS...9 INCHES SO FAR AT BRISTLECONE SNOTEL
AND TOP OF SKI AREA IN LEE CANYON AND 5 INCHES IN RAINBOW CANYON.
UPSLOPE NORTHEAST TO EASTERLY FLOW AND TEMPERATURES IN THE TEENS ARE
OBVIOUSLY PRODUCING A LOT OF SNOW ACCUMULATION EVEN THOUGH
PRECIPITABLE WATER VALUES ARE NOT THAT IMPRESSIVE AT LESS THAN A
HALF-INCH.
ALSO...REPLACED THE WIND ADVISORY WITH A HIGH WIND WARNING FOR THE
EASTERN MOJAVE DESERT AS WINDS FROM MOUNTAIN PASS WEST TO BAKER WILL
LIKELY EXCEED 60 MPH AT TIMES WITH POTENTIAL DOWNSLOPE ENHANCEMENT
AND PRODUCE HAZARDOUS DRIVING CONDITIONS ALONG I-15. THE SURFACE
PRESSURE GRADIENT IS MOST INTENSE ACROSS INYO...NYE AND LINCOLN
COUNTIES AND WILL SUPPORT HIGH WINDS THERE AND DOWN THROUGH SAN
BERNARDINO COUNTIES. WINDS AND PRECIPITATION WILL DIMINISH TONIGHT
AND FRIDAY MORNING AS THE UPPER LOW BEGINS TO OPEN UP AND LIFT
ACROSS ARIZONA.
&&
.LONG TERM...THE SECOND SYSTEM WILL DESCEND INTO THE CWA SATURDAY TO
BRING IN ANOTHER SHOT OF COLD AIR AND PRECIPITATION. MODELS HAVE
COME INTO CLOSER AGREEMENT ON THIS ONE AND HAVE TRENDED TOWARDS IT
SLIDING SOUTH IN THE EASTERN PART OF THE CWA. LEFT INHERITED
FORECAST POP FORECASTS PRETTY MUCH ALONE...WHICH KEEPS THEM IN
LINCOLN AND MOHAVE COUNTIES SATURDAY AND SUNDAY. BREEZY NORTH WINDS
ARE LIKELY OVER MUCH OF THE AREA WITH SOME WINDY AREAS SATURDAY. THE
SYSTEM SHOULD BE OUT OF THE AREA BY EARLY MONDAY. NORTH TO
NORTHWEST FLOW WILL BE OVER THE AREA FROM THE STRONG RIDGING OVER
THE EASTERN PACIFIC AND TROUGHING HANGING BACK FROM HUDSON BAY TO
THE SOUTHWEST STATES FOR THE REST OF THE EXTENDED. TEMPERATURES WILL
RECOVER LITTLE EARLY NEXT WEEK AND REMAIN BELOW NORMAL VALUES.
&&
.AVIATION...FOR MCCARRAN...NORTH WINDS OF 20-25KTS AND GUSTS TO
30-35KTS WILL CONTINUE EARLY THIS MORNING. THE WIND SPEEDS WILL
INCREASE THIS MORNING APPROXIMATELY AFTER 16Z WITH SUSTAINED WINDS
RANGING FROM 25-30KTS AND GUSTS TO AROUND 40-45KTS. IT IS POSSIBLE
THE WINDS COULD BE STRONGER AND MAY PROMPT THE ISSUANCE OF AN
AIRPORT WEATHER WARNING AFFECTING GROUND OPERATIONS. THESE STRONGER
NORTH WINDS WILL ABATE IN THE MID TO LATE AFTERNOON TIME FRAME.
LIGHT RAIN OR VIRGA WILL PERSIST IN THE AREA THROUGH TODAY AND INTO
FRIDAY MORNING. DIFFICULT TO TIME WHEN A BAND OF RAIN WILL PASS OVER
KLAS. WHEN THEY DO THE WIND SPEEDS WILL DECREASE. CEILINGS COULD
DROP DOWN TO 3000 FEET TEMPORARILY UNDER SOME OF THE SHOWERS. THE
LOCAL MOUNTAINS TOPS WILL BE OBSCURED AND HAVE SNOW FALL OVER THEM.
CONDITIONS WILL IMPROVE CONSIDERABLY FRIDAY MORNING WITH THE RAIN
CHANCES MUCH LOWER ALONG WITH DIMINISHED WIND SPEEDS.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THE STRONG NORTH WINDS WILL CONTINUE OVER THE AREA
TODAY AND INTO TONIGHT. MOST AREAS WILL SEE WINDS OF 25-35KTS AND
GUSTS OF 35-45KTS BY LATER THIS MORNING. SOME AREAS FAVORABLE FOR
FUNNELING NORTH WINDS COULD SEE MUCH HIGH WIND SPEEDS AND
GUSTS...SUCH AS THE OWENS AND COLORADO RIVER VALLEYS. LIGHTER NORTH
WINDS ARE EXPECTED ON FRIDAY EXCEPT FOR ENHANCED NORTH WINDS ALONG
THE COLORADO RIVER VALLEY. RAIN AND SNOW SHOWERS CHANCES WILL OCCUR
THROUGH FRIDAY MORNING OVER MOST AREAS. CEILINGS COULD DROP TO BELOW
3000 FEET UNDER THE SHOWERS...WHILE MOUNTAIN AREAS WILL HAVE THEIR
HIGHER ELEVATION OBSCURED.

A COLD STORM SYSTEM PRESENTLY OVER SOUTHEAST CALIFORNIA HAS CONTINUED TO PRODUCE PRECIPITATION ACROSS MUCH OF CLARK COUNTY THIS MORNING. A COLD NORTHEAST FLOW AROUND THIS STORM SYSTEM HAS ALLOWED TEMPERATURES TO DROP INTO THE MID TO UPPER 30S ACROSS MUCH OF SOUTHERN CLARK COUNTY AND WESTERN AND SOUTHERN PORTIONS OF THE LAS VEGAS VALLEY. THIS HAS ALLOWED PRECIPITATION TO FALL IN PORTIONS OF SOUTHERN CLARK COUNTY AND THE LAS VEGAS VALLEY AS A MIX OF RAIN AND SNOW OR ALL SNOW IN ELEVATIONS ABOVE 3000 FEET. SO FAR REPORTS OF SNOW MIXED WITH RAIN HAVE BEEN RECEIVED THIS MORNING FROM ANTHEM AND SUMMERLIN IN THE LAS VEGAS VALLEY AS WELL AS IN JEAN. A LIGHT COATING OF SNOW WAS REPORTED IN SEARCHLIGHT. TEMPERATURES WILL STRUGGLE TO WARM TODAY IN THESE AREAS...THEREFORE SNOW MAY CONTINUE TO MIX WITH RAIN THROUGH THE DAY IN ELEVATIONS ABOVE 3000 FEET WITH SOME AREAS SEEING ALL SNOW ESPECIALLY ABOVE 3500 FEET. THE COMBINATION OF FALLING TEMPERATURES AND HEAVIER BURSTS OF PRECIPITATION THIS EVENING INTO TONIGHT WILL CREATE THE POTENTIAL FOR SNOW LEVELS TO DROP AS LOW AS 2800 FEET ACROSS CLARK COUNTY LATE THURSDAY EVENING INTO EARLY FRIDAY MORNING. A TOTAL OF 1 TO 3 INCHES OF SNOW IS POSSIBLE THROUGH FRIDAY MORNING IN PLACES SUCH AS BLUE DIAMOND...SEARCHLIGHT AND IN AREAS ALONG NIPTON ROAD BETWEEN SEARCHLIGHT AND THE CALIFORNIA-NEVADA BORDER. FOR THE LAS VEGAS VALLEY...MOST OF THE PRECIPITATION THAT FALLS WITH THIS EVENT WILL BE IN THE FORM OF RAIN. IF THE PRECIPITATION FALLS HEAVY ENOUGH WHEN TEMPERATURES ARE COLD ENOUGH...AS MUCH AS AN INCH OF SNOW MAY ACCUMULATE IN THE LAS VEGAS VALLEY ON UNPAVED SURFACES ESPECIALLY IN AREAS AT OR ABOVE 3000 FEET.
