AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
344 AM PST SAT JAN 21 2012

.SHORT TERM...

IMPRESSIVELY WET WINTER STORM CONTINUES TO POUND THE SIERRA AND
WESTERN NV THIS MORNING. SNOW LEVELS ARE FINALLY BEGINNING TO COME
DOWN IN THE SIERRA, WITH SLIDE MOUNTAIN DOWN TO 26 DEGREES AND SNOW
LEVELS AROUND 6500 FEET. THE WELL-ADVERTISED DEEP MOISTURE PLUME
HASN'T FAILED TO IMPRESS. RAINFALL HAS BEEN HEAVY, ESPECIALLY OVER
THE LAST 12 HOURS, WITH RATES OF UP TO 0.4" PER HOUR AT TIMES IN THE
SIERRA. THERE HAS BEEN SO MUCH RAINFALL THAT LAKE TAHOE HAS RISEN BY
MORE THAN 2 INCHES IN THE LAST 24 HOURS. WE HAVEN'T HAD ANY ISSUES
WITH RIVERS OR STREAMS, BUT ALL HAVE SEEN RISES OVER THE LAST 24
HOURS. WITH THE HEAVIEST RAINFALL TAPERING OFF AROUND THE RENO AREA,
WILL DROP THE FLASH FLOOD WATCH WITH THE MORNING FORECAST PACKAGE.

RAINFALL AMOUNTS AROUND THE TAHOE BASIN HAVE BEEN ANYWHERE FROM 1.5"
ON THE NEVADA SIDE AND AROUND 3.5" ON THE CALIFORNIA SIDE. AS FOR
RAINFALL IN WESTERN NEVADA, RENO AND CARSON CITY HAVE GOTTEN ABOUT
0.6" SO FAR, WITH ABOUT 1.5" OF RAINFALL IN THE FOOTHILLS WEST OF
HIGHWAY 395. HAVEN'T GOTTEN MANY REPORTS OF SNOW AMOUNTS YET, SINCE
SNOW LEVELS HAVE SPENT MOVE OF THE NIGHT ABOVE 8500 FEET. WOULDN'T
BE SURPRISED THAT SOME OF THE HIGHEST ELEVATIONS AROUND LAKE TAHOE
ABOVE 8500 FEET GOT 2-4 FEET OF HEAVY WET SNOW.

AS THE COLDER AIR MOVES IN THIS MORNING, SNOW LEVELS WILL COME DOWN
TO NEAR VALLEY FLOORS BY MIDDAY. WE DO EXPECT TO SEE ACCUMULATING
SNOW THROUGH THE MORNING IN THE SIERRA, ALTHOUGH THE PRECIPITATION
RATES WON'T BE AS MUCH AS WHAT WE SAW LAST NIGHT. I DID BUMP UP SNOW
LEVELS THROUGH THE REST OF THE MORNING, WITH SNOW LIKELY NOT
ACCUMULATING DOWN TO LAKE LEVEL UNTIL AFTER 7 AM. LATEST NAM STILL
SHOWS A BURST OF PRECIP IN THE SIERRA BETWEEN 7 AM AND 10 AM, WHEN
SNOW LEVELS SHOULD FINALLY BE DOWN TO LAKE LEVEL. WE COULD SEE AN
ADDITIONAL 4-8 INCHES ABOVE 7000FT THROUGH, WITH 2-4 INCHES TO LAKE
TAHOE LEVEL. IF THIS DOESN'T MATERIALIZE, THEN WE WON'T SEE MUCH AT
ALL FOR ACCUMULATIONS AT THE LAKE. AS FOR MONO COUNTY, THEY'VE SEEN
ABOUT 10 INCHES SO FAR ALONG THE CREST, BUT WILL SEE EVEN MORE AT
THE MAIN PRECIP BAND SAGS SOUTH OVER THE NEXT COUPLE HOURS.

WITH HIGHER SNOW LEVELS EXPECTED, THIS MEANS THAT THE RENO-CARSON
CITY AREAS WON'T BE SEEING MUCH SNOW AT THE VALLEY FLOORS. STILL
EXPECTING AN INCH OR TWO FOR THE FOOTHILLS ABOVE 5500 FEET,
INCLUDING VIRGINIA CITY, BUT SNOW LEVELS WILL HAVE A HARD TIME
LOWERING TO VALLEY FLOORS UNTIL THIS AFTERNOON, WHEN MOST OF THE
PRECIP WILL BE DONE.

WINDS ARE EXPECTED TO PICK UP AGAIN THIS AFTERNOON, WITH GUSTS UP TO
55 MPH IN WESTERN NEVADA. WIND ADVISORY HAS BEEN POSTED FOR THE
WESTERN NEVADA BASIN AND RANGE AS WELL AS MINERAL AND SOUTHERN LYON
COUNTIES, WHERE THE GRADIENTS WILL BE THE STRONGEST. PRECIPITATION
WILL REALLY DROP OFF THIS EVENING AND OVERNIGHT AS SHORTWAVE RIDGING
BUILDS IN TEMPORARILY. LOWERED POPS AND QPF FOR THE TONIGHT PERIOD,
MAY NEED TO BE REMOVED ALL TOGETHER. HOON

.LONG TERM...SUNDAY THROUGH FRIDAY...

FOR THE NEXT SYSTEM SUNDAY INTO MONDAY THE ECMWF HAS COME A BIT MORE
IN LINE WITH THE GFS AND GEM...MAINLY BECAUSE THEY HAVE SLOWED JUST
A BIT. ECMWF REMAINS THE DRIER OF THESE THREE WHILE THE NAM IS
SHOWING ITS TYPICAL DRY BIAS EAST OF THE SIERRA. SNOW LEVELS AND
TIMING OF THE PCPN WILL BE THE PRIMARY PROBLEMS WITH THIS SYSTEM AS
MODELS CONTINUE TO TRY TO BUMP UP MID LVL TEMPS AHEAD OF THE PRIMARY
SYSTEM. THIS WARMING MAY BE SLIGHTLY OFF SET BY INCREASED PCPN
INTENSITY LATER IN THE DAY. THIS WILL DEFINITELY BE A COLDER SYSTEM
OVERALL THAN THE CURRENT SYSTEM MOVING THROUGH BUT IT IS ALSO DRIER.
THIS WILL REDUCE SNOW AMOUNTS...BUT WHERE SNOW DOES FALL RATIOS WILL
BE HIGHER THAN THE CURRENT SYSTEM. AS GEFS ENSEMBLE MEMBERS LARGELY
FAVOR THE TIMING OF THE GFS/GEM SOLUTIONS HAVE NOT MADE SIGNIFICANT
CHANGES TO THE PREVIOUS FORECAST OTHER THAN TO DELAY THE HIGHEST
POPS JUST A BIT UNTIL LATER SUNDAY. ALSO TRIED TO SHOW A RISE IN
SNOW LEVELS A BIT MORE OVER CURRENT FORECAST FOR SUNDAY/SUNDAY
EVENING...THEN BRING THE SNOW LEVELS BACK DOWN SUNDAY NIGHT INTO
MONDAY.

IT IS LIKELY THAT ADVISORIES WILL BE NEEDED FOR THE WESTERN PORTIONS
OF LASSEN AND SIERRA COUNTIES ALONG WITH THE TAHOE AREA AND INTO
MONO COUNTY FOR LATE SUNDAY INTO EARLY MONDAY. LOW END WARNING IS
NOT OUT OF THE QUESTION FOR THE HIGHER ELEVATIONS OF THE TAHOE
BASIN.

WINDS AHEAD OF THIS SYSTEM WILL LIKELY BECOME GUSTY EARLY SUNDAY...
BUT SHOULD REMAIN SUB ADVISORY EAST OF THE SIERRA. LAKE WIND
ADVISORIES MAY BE NEEDED EARLY SUNDAY. THEN WITH ONSET OF PCPN WINDS
WILL DECREASE A BIT THROUGH THE AFTERNOON AND EVENING. BEST SPILL
OVER CHANCES FOR WESTERN NEVADA WILL BE SUNDAY EVENING AND OVERNIGHT.

MODELS IN GOOD AGREEMENT THAT UPPER TROF WILL MOVE ACROSS THE REGION
BY LATE MONDAY AND BRING AN END TO SHOWERS. ANOTHER WEAK AREA OF LOW
PRESSURE TRIES TO MOVE OVER THE FAR NRN SECTIONS OF THE CWA BY LATE
TUESDAY BUT IS BEING HELD OFF BY A FLAT RIDGE. WILL INCLUDE SOME
VERY LOW POPS OVER THE FAR NRN CWA TO ACCOUNT FOR THIS BIT OF WARM
AIR ADVECTION PCPN. MLF

ON WEDNESDAY THE FLAT RIDGE OFF OF THE SOUTHERN CALIFORNIA COAST
PUSHES THE MAIN JET NORTH OF THE OREGON BORDER. A PLUME OF UPPER
LEVEL MOISTURE AND WEEK JET DYNAMICS KEEP THE CHANCE OF A FEW LIGHT
SHOWERS IN THE FAR NORTHERN ZONES. BUMPED UP POPS FOR WEDNESDAY
NIGHT AND THURSDAY MORNING AS MODELS ARE SLOWING THE PROGRESSION OF
THE JET. ZTT/MLF
&&

.AVIATION...

BAND OF RAIN/SNOW CONTINUES MOVING THROUGH THE FORECAST AREA EARLY
THIS MORNING AND WILL PERSIST THROUGH LATE MORNING. ANOTHER BAND OF
PCPN IS MOVING ON SHORE AND WILL AFFECT MAINLY THE SIERRA THIS
AFTERNOON AND EARLY THIS EVENING. SNOW LEVELS ARE FALLING NOW AND
KTR/KTVL/KMMH SHOULD BE ALL SNOW AFTER 6 AM. MVFR TO IFR CONDITIONS
SHOULD PERSIST AT THESE TERMINALS UNTIL THE MAIN UPPER TROF PASSES
TONIGHT AND SNOW SHOWERS END. AT KRNO SOME LIGHT RAIN WITH LOWER
CIGS BELOW 2000 FEET ARE LIKELY EARLY THIS MORNING WITH A MIX OF
RAIN AND SNOW AFTER 7 AM. CIGS TO DROP TO AROUND 1000-2000 FT IN THE
HEAVIEST PCPN THIS MORNING. WINDS INCREASE AT THE TERMINALS TODAY IN
COLD AIR BEHIND THE MAIN BAND OF PCPN AS WELL.

GUSTY WINDS CONTINUE OVER THE RIDGES TO AS HIGH AS 90 MPH THIS
MORNING WITH A DECREASE IN THE AFTERNOON. LOW CLOUDS AND VSBYS WILL
OBSCURE MTNS THROUGH THE DAY. MLF
