AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
945 PM PST SUN NOV 21 2010

.UPDATE...
LOOKING AT SNOW FALL RATES AND POTENTIAL SNOW FALL RATES FOR THE
TAHOE AREA...THE SIERRA CREST AND THE HIGHER ELEVATIONS TO THE
NORTH INTO WESTERN LASSEN COUNTY...THINK THE SNOW ACCUMULATIONS
NEED TO BE RAISED JUST A BIT. WILL NOT GO ABOVE ADVISORY CRITERIA
BUT WILL BUMP UP THE ACCUMULATIONS A LITTLE FOR TONIGHT. MLF

&&

.PREVIOUS DISCUSSION... /ISSUED 906 PM PST SUN NOV 21 2010/

UPDATE...
NO SIGNIFICANT UPDATES TO THE EVENING/OVERNIGHT FORECAST AS IR
SATELLITE IMAGERY AND RADAR IMAGERY BOTH STILL SHOWS THE APPROACH
OF THE NEXT FAST MOVING SHORT WAVE FROM THE NORTH. COLDER CLOUD
TOPS HAVE MOVED INTO THE REGION AHEAD OF THE SHORT WAVE ON IR
IMAGERY WHILE SHOWERS HAVE BEEN INCREASING ON THE WEST SIDE OF THE
NORTHERN SIERRA AND INTO NRN CA AHEAD OF AND WITH THE SHORT WAVE
RESPECTIVELY. HAVE SEEN SOME LIGHTNING STRIKES IN NRN CA AS WELL
IN VICINITY OF BEST MID LVL INSTABILITY. THIS COULD ENHANCE SNOW
FALL RATES IN NRN PORTION OF THE CWA TONIGHT IF THIS INSTABILITY
HOLDS TOGETHER AND MOVES EAST. RIGHT NOW WINTER WEATHER ADVISORIES
LOOK REASONABLE. AM A LITTLE CONCERNED THAT THE EAST
SIDE...RENO/CARSON CITY AREA...MAY NOT PICK UP MUCH ACCUMULATION
BY DAYBREAK. BUT ANY LITTLE BIT COULD CAUSE PROBLEMS WITH THE
MORNING COMMUTE.

MAD A FEW MINOR TWEAKS TO THE WINDS IN THE LOWEST VALLEYS EARLY
MONDAY TO ACCOUNT FOR LIMITED MIXING UNTIL THE APPROACH OF THE
NEXT UPPER TROF LATE MONDAY AFTERNOON/MONDAY EVENING. WITH LITTLE
IF ANY PCPN EXPECTED BY LATE MONDAY MORNING THE WINTER WEATHER
ADVISORIES WILL LIKELY BE LIFTED BY LATE MORNING...BUT THERE IS
A STRONG POSSIBILITY THAT WINDS ON BOTH PYRAMID LAKE AND LAKE
TAHOE WILL MEET/EXCEED LAKE WIND ADVISORY CRITERIA. SO HAVE OPTED
TO ISSUE ADVISORIES FOR BOTH OF THOSE LAKES FOR LATE MONDAY
MORNING INTO MONDAY EVENING WITH THIS UPDATE.

LATEST MODEL RUNS WOULD SUPPORT A SLIGHT SLOWING OF THE NEXT
SYSTEM FOR LATE MONDAY NIGHT AND TUESDAY DROPPING DOWN FROM THE
NORTH. TIMING FOR CURRENT WATCHES COVERING THIS FEATURE MAY NEED
TO BE ADJUSTED A BIT. EVEN THOUGH PWATS ARE LOW WITH THIS
FEATURE...MODELS INDICATE FAIRLY STRONG FRONTOGENESIS BY TUESDAY
MORNING/AFTERNOON ALONG WITH LIFT AND ENOUGH MSTR TO SQUEEZE OUT
SNOW FALL RATES AROUND 1-2 INCHES PER HOUR FOR A COUPLE OF HOURS
IN WRN NV...MAYBE HIGHER ON THE ERN SLOPES OF THE SIERRA. MLF

PREVIOUS DISCUSSION... /ISSUED 519 PM PST SUN NOV 21 2010/

UPDATE...
OBSERVATIONS FROM ANAHO ISLAND ARE MISSING THIS EVENING BUT
OBSERVATIONS FROM SUTCLIFFE INDICATE WIND SPEEDS HAVE DROPPED
BEFORE ADVISORY CRITERIA AND WITH THE LAKE CLOSED AT SUNSET HAVE
ALLOWED TO LAKE WIND ADVISORY FOR PYRAMID TO EXPIRE. SNOW SHOWERS
CONTINUE IN THE SIERRA THIS EVENING WITH MORE SHOWERS INCREASING
IN NRN CA ASSOCIATED WITH THE NEXT WAVE FORECAST TO DROP INTO THE
REGION LATER TONIGHT. AM ALSO SEEING A SLIGHT INCREASE IN THE
COVERAGE OF COLD CLOUD TOPS OVER NRN CA SO AM BECOMING MORE
CONFIDENT THAT THESE SHOWERS WILL FILL IN AND PRODUCE SNOW SHOWERS
ON OUR SIDE AND THROUGH THE SIERRA LATE TONIGHT AND EARLY MONDAY.
SO WILL LEAVE THE WINTER WEATHER ADVISORIES IN PLACE. WILL LOOK AT
THE LATEST GUIDANCE LATER THIS EVENING AND DETERMINE WHETHER
WINDS WILL BE STRONG ENOUGH DURING THE AFTERNOON MONDAY FOR
ADDITIONAL LAKE WIND ADVISORIES. AT FIRST GLANCE THE ANSWER WOULD
APPEAR TO BE YES GIVEN THE INCREASE IN PRESSURE GRADIENT AHEAD OF
THE NEXT SFC BOUNDARY LATE MONDAY AFTERNOON...BUT WILL ADDRESS
THIS IN A FEW HOURS. MLF

PREVIOUS DISCUSSION... /ISSUED 330 PM PST SUN NOV 21 2010/

SHORT TERM...

ACTIVE WINTER WEATHER EXPECTED TO CONTINUE THROUGH MIDWEEK...

DEPARTING WINTER STORM WILL PUSH EAST...BUT COLD NORTHWEST FLOW WILL
CONTINUE THROUGH MONDAY. A COUPLE OF WAVES WILL CONTINUE TO BRING
ACTIVE WINTER WEATHER TO THE REGION THROUGH MIDWEEK. WINTER STORM
WARNINGS IN THE SIERRA WILL BE REPLACED WITH SOME WINTER WEATHER
ADVISORIES THROUGH MONDAY MORNING AS A WEAK SYSTEM DROPS OUT OF
OREGON AND INTO NORTHERN CA/NV. WINTER STORM WATCHES ARE IN PLACE
FOR MONDAY NIGHT INTO TUESDAY AFTERNOON FOR AREAS NORTH OF HIGHWAY
50 AS VERY STRONG ARCTIC COLD FRONT PUSHES OUT OF CANADA. AS FOR
WINDS...GUSTY WINDS WILL CONTINUE THROUGH THE SHORT TERM...WITH
LAKE WIND ADVISORIES LIKELY NEEDED AGAIN FOR TOMORROW. STRONG
WINDS MONDAY NIGHT AND TUESDAY WILL MAKE FOR SOME AREAS OF BLOWING
SNOW AND LOCALIZED WHITEOUT CONDITIONS POSSIBLE AS THE FRONT MOVES
THROUGH THE REGION.

SNOW IS EXPECTED TO INCREASE IN INTENSITY TONIGHT IN THE SIERRA
ZONES...AS A FAST MOVING SHORTWAVE DROPS THROUGH NORTHERN CA/NV. NOT
EXPECTING ANY PARTICULARLY HEAVY AMOUNTS...ALTHOUGH WILL ISSUE A
WINTER WEATHER ADVISORY FROM RENO-TAHOE NORTHWARD AND INTO
NORTHERN WASHOE COUNTY. THIS WAVE TONIGHT WAS LOOKING MUCH BETTER
A COUPLE DAYS AGO...BUT HAS TRENDED DRIER AND LESS IMPRESSIVE
ALTHOUGH STILL EXPECTED TO MAKE AN IMPACT TO THE REGION.

WE COULD SEE UP TO A QUICK INCH OR SO ON THE VALLEY FLOORS TONIGHT
IN WESTERN NV...INCLUDING RENO-SPARKS-CARSON CITY. THIS COULD CAUSE
SOME ISSUES FOR THE MORNING COMMUTE MONDAY MORNING. ROADS HAVE
CLEARED OUT FOR THE MOST PART IN WESTERN NV AND SHOULDN'T HAVE ANY
RESIDUAL ICE FROM LAST NIGHTS SNOW...BUT WITH SOME LIGHT SNOW
TONIGHT THE MORNING COMMUTE COULD GET PRETTY DICEY. THE MAJORITY
OF THE PRECIP ASSOCIATED WITH THIS WAVE WILL BE IN THE HIGHER
ELEVATIONS OF LASSEN-PLUMAS-SIERRA COUNTIES...AS WELL AS AROUND
THE TAHOE BASIN...WITH 6-12 INCHES ABOVE 7000 FEET AND 3-6 INCHES
BELOW 7000 FEET. NORTH OF RENO INTO NORTHERN WASHOE COUNTY AND
SURPRISE VALLEY AND LOWER ELEVATIONS OF NORTHEASTERN CA...WE COULD
SEE SOME LOCALLY HIGHER AMOUNTS UP TO 4 INCHES.

THE BIGGER CONCERN IN THE SHORT TERM IS THE ARCTIC FRONT EXPECTED TO
PUSH INTO THE REGION MONDAY NIGHT INTO TUESDAY. THIS FRONT IS
EXTREMELY DYNAMIC...WITH VERY STRONG FRONTOGENESIS ALONG THE COLD
FRONT AND 700MB TEMPS BEHIND THE FRONT DROPPING TO LESS THAN -15C!
MODELS HAVE BEEN TRENDING A BIT SLOWER WITH THE COLD FRONT...PUSHING
IT THROUGH RENO-TAHOE AROUND LATE MORNING ON TUESDAY INSTEAD OF
EARLY MORNING TUESDAY AS PREVIOUS RUNS HAD SHOWN. WITH THE
UNCERTAINTY IN THE TIMING...OPTED TO GO WITH A BROAD MENTION OF SNOW
ON TUESDAY FOR MOST AREAS INSTEAD OF TRYING TO NARROW DOWN A
TIMEFRAME.

WINTER STORM WATCHES HAVE BEEN ISSUED FOR ALL AREAS FROM HIGHWAY 50
NORTHWARD FOR MONDAY NIGHT AND TUESDAY. THIS FRONT WILL BRING STRONG
WINDS...A BURST OF HEAVY SNOWFALL WITH RATES UP TO 2 INCHES PER HOUR
DOWN TO THE VALLEY FLOORS. IT WON'T LAST LONG HOWEVER...PROBABLY
ONLY FOR A FEW HOURS DURING FRONTAL PASSAGE...BUT THIS TYPE OF
"INSIDE SLIDER" IS NOTORIOUS FOR BRINGING HEAVY SNOW AMOUNTS DOWN TO
THE LOWER ELEVATIONS OF WESTERN NV AND NORTHEASTERN CA.

AS FAR AS SNOW AMOUNTS IN THE SIERRA...STRONG LIFT ALONG THE FRONT
AND WITHIN THE DENDRITIC GROWTH ZONE ALOFT WILL CAUSE SOME HEAVY
AMOUNTS OF SNOW IN THE SIERRA. AM VERY CONFIDENT THAT WE SHOULD SEE
ANOTHER FOOT OR TWO ABOVE 7000 FEET AND UP TO A FOOT BELOW 7000
FEET. AS FOR THE LOWER VALLEYS OF WESTERN NV...WE ARE ONLY EXPECTING
ABOUT 2 TO 4 INCHES OF SNOW...BUT THE IMPACTS WILL BE HIGHER WITH
THIS INCOMING SLIDER DURING MIDWEEK AND POTENTIALLY DURING THE
TUESDAY COMMUTE.  HOON

LONG TERM...WEDNESDAY THROUGH SUNDAY...
UPPER TROUGH WITH VERY COLD AIRMASS WILL BE SHIFTING OUT OF THE
REGION AT BEGINNING OF PERIOD WITH SHORTWAVE RIDGE DOMINATING THE
LAST HALF OF THE WEEK. THIS SHOULD ALLOW FOR RAPID HEIGHT RISES AND
WARMING ALOFT. RIDGES ARE GOING TO WARM WEDNESDAY NIGHT AND THURSDAY
WITH STRONG NON-DIURNAL TRENDS FOR THE HIGHER ELEVATIONS. FOR LOWER
ELEVATIONS...THE VERY COLD AIRMASS WILL BE LOCKED INTO PLACE FOR
SEVERAL DAYS AS STRONG INVERSIONS DEVELOP WITH WINDS/MIXING AT A
MINIMUM. THUS KEPT THE FORECAST TEMPERATURES BELOW MOS GUIDANCE
ESPECIALLY FOR DAYTIME HIGHS WED-FRI. UNDER CLEAR SKIES AND AN
ALMOST CERTAIN SNOW COVER...MANY OVERNIGHT TEMPERATURES ARE GOING TO
FALL TO RECORD LEVELS AT LEAST FOR WED/THU MORNINGS AND MAYBE EVEN
FRI MORNING. THIS WOULD PUT READINGS INTO THE SINGLE DIGITS ABOVE
AND BELOW ZERO IN MOST VALLEYS. MOS GUIDANCE SUGGESTS A FEW COLDER
LOCATIONS COULD GET AS LOW AS 20 BELOW ZERO!

ANOTHER TROUGH WILL ARRIVE NEXT WEEKEND WITH RIDGE SLIDING EAST SAT
AND FRONT/BAND OF PRECIPITATION FOLLOWING SAT NIGHT INTO SUN. MODELS
SHOW HIGHLY AMPLIFIED FEATURE AND SOUTHERLY FLOW IN ADVANCE OF
SYSTEM SAT-SAT NIGHT. THIS WILL RESULT IN LITTLE SPILLOVER UNTIL
MAIN TROUGH PUSHES ACROSS THE SIERRA. UPSTREAM SYSTEM SHOULD MAKE
THIS WEEKEND SYSTEM FAIRLY PROGRESSIVE. WHILE NOT AS COLD AS THE
CURRENT LOW PRESSURE AREA...SNOW LEVELS SHOULD BEGIN JUST ABOVE THE
LOWER VALLEYS AND THEN FALL TO MOST VALLEY FLOORS AS THE FRONT
PASSES. AT THIS TIME IT APPEARS TO BE A MODERATE SNOWFALL PRODUCER
FOR THE SIERRA WITH LIGHT AMOUNTS FOR LOWER VALLEYS. HOHMANN

AVIATION...
MAIN UPPER LOW IS PULLING AWAY WHILE ANOTHER DISTURBANCE DROPS DOWN
THE WEST COAST AND KEEPS LONGWAVE TROUGH IN POSITION OVER THE
WESTERN CONUS. SNOW SHOWERS WILL STAY CONFINED MAINLY TO THE CREST
UNTIL THIS EVENING WHEN UPSTREAM DISTURBANCE WILL INCREASE LIFT AND
BRING A DEEPER MOISTURE PROFILE. SNOW SHOWERS WILL BECOME MORE
WIDESPREAD IN THE TAHOE BASIN OVERNIGHT AND THEN BACK OFF AGAIN TO
SCATTERED SNOW SHOWERS CONCENTRATED NEAR THE CREST MONDAY MORNING.

KTVL/KTRK...ALTERNATING BETWEEN VFR AND IFR CIGS/VIS THRU 02Z. LIGHT
SNOW WITH CONSISTENT MVFR/IFR CIGS/VIS DEVELOPING 02Z-04Z MON
THROUGH 15Z. CIGS/VSBY GENERALLY BELOW MINIMUMS DURING HEAVIER
