AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
345 AM PST WED FEB 16 2011

.SHORT TERM...
A STRONG COLD FRONT MOVING THROUGH THE REGION TODAY WILL BRING SNOW
TO THE SIERRA AND WRN NV VALLEYS...WITH THE HEAVIEST PRECIP FALLING
THIS MORNING. CURRENT RADAR SHOWS WIDESPREAD MODERATE TO HEAVY SNOW
OVER THE SIERRA...WITH SPILLOVER EXTENDING EAST TO PYRAMID LAKE AND
FERNLEY. RAIN-SNOW MIX ON THE VALLEY FLOORS SHOULD BECOME ALL SNOW
LATER THIS MORNING AS THE FRONT MOVES THROUGH. ACCUMULATIONS ON THE
VALLEY FLOOR IN RENO ARE HEAVILY DEPENDENT ON WHEN THE TRANSITION TO
SNOW OCCURS...AND ALSO WHEN ROAD SURFACES FINALLY COOL TO BELOW
FREEZING. AREAS JUST ABOVE THE VALLEY FLOORS HOWEVER SHOULD EASILY
SEE 2 TO 4 INCHES OF SNOW TODAY WITH LOCALLY HEAVIER AMOUNTS IN THE
FOOTHILLS. ROADWAYS COULD BECOME PRETTY SLICK AS MELTING SNOW AND
RUNOFF BEGINS TO FREEZE AS COLDER AIR FILTERS IN BEHIND THE FRONT.
IN THE SIERRA...FORECAST STILL ON TRACK WITH MULTIPLE FEET OF SNOW
EXPECTED. MOIST UPSLOPE FLOW WILL KEEP SNOW SHOWERS GOING THROUGH
THE AFTERNOON OVER THE SIERRA...AND EVEN INTO THE VALLEYS OF WRN NV
AS THE ATMOSPHERE BECOMES INCREASING UNSTABLE WITH STRONG COLD
ADVECTION ALOFT.

ADDITIONAL SHORT WAVE ENERGY WILL MOVE THROUGH THIS EVENING AND
EARLY TONIGHT...BRINGING ANOTHER WAVE OF SNOW SHOWERS TO THE SIERRA.
DOES NOT LOOK LIKE MUCH ADDITIONAL ACCUMULATION WITH THIS FEATURE AS
IT MOVES QUICKLY THROUGH THE AREA...2-4 INCHES WITH LOCALLY HIGHER
AMOUNTS NEAR THE SIERRA CREST.

UPSTREAM ENERGY DIVING SOUTHWARD WILL CAUSE THE LONG WAVE TROUGH TO
DEEPEN OFF THE WEST COAST...WITH A PLUME OF MOISTURE PIVOTING ABOUT
THE SIERRA AND WRN NV VALLEYS THURSDAY NIGHT THROUGH FRIDAY. MODELS
HAVE COME INTO MUCH BETTER AGREEMENT SHOWING GREATER THAN 2 INCHES
OF QPF OVER THE SIERRA...WITH THE HEAVIEST AMOUNT CENTERED ON ALPINE
AND MONO COUNTIES. RAISED POPS CONSIDERABLY ALONG THE SIERRA AND THE
395 CORRIDOR FOR THURSDAY NIGHT THROUGH FRIDAY...AND ISSUED A WINTER
STORM WATCH FOR THE TAHOE BASIN AND MONO COUNTY. THERE COULD EASILY
BE AN ADDITIONAL 2-3 FEET OF SNOW NEAR THE SIERRA CREST WITH THIS
SYSTEM. A LONG FETCH OF DEEP ISENTROPIC LIFT AS ADVERTISED BY THE
MODELS WOULD HELP OVERCOME SOME OF THE SHADOWING AFFECTS OF THE
SOUTH FLOW ALOFT AND BRING ANOTHER ROUND OF STEADY SNOW TO THE WRN
NV VALLEYS INCLUDING RENO-CC. FEEL THAT CURRENT QPF/POP FORECAST FOR
THE VALLEYS SOUTH OF I-80 IS A BIT TO CONSERVATIVE AT THIS TIME
GIVEN THE AMOUNT OF ISENTROPIC LIFT PROJECTED. ADDITIONAL WINTER
PRODUCTS MAY BE NEEDED FOR THESE AREAS AS ACCUMULATING SNOWFALL IS
LOOKING MORE LIKELY. SCV

.LONG TERM...SATURDAY THROUGH TUESDAY...

BY SATURDAY LOW PRESSURE WILL BE MOVING INLAND OVER CA/NV WITH
SCATTERED SNOW SHOWERS ACROSS THE REGION. THE LOW WILL PUSH OFF TO
THE EAST ON SUNDAY...ALTHOUGH LATEST EURO WANTS TO KEEP THE LOW OVER
US FOR ONE DAY LONGER THAN THE GFS. KEPT A CHANCE FOR SHOWERS FOR
SUNDAY ACROSS THE AREA TO ACCOUNT FOR THE SLOWER ECMWF.

THERE REMAINS A LOT OF UNCERTAINTY PAST SUNDAY...WITH MODELS FLIP
FLOPPING ON THE TRACK OF THE NEXT STORM TO AFFECT THE WEST COAST.
LEFT IN A CHANCE/SLIGHT CHANCE OF SHOWERS THROUGH THE START OF NEXT
WEEK...ALTHOUGH THERE WILL PROBABLY BE A BREAK IN THE WEATHER
SOMETIME SUN-MON AS WE GET SOME SHORTWAVE RIDGING INTO THE REGION.

THE NEXT LOW TO DROP OUT OF THE GULF OF AK WILL PUSH DOWN THE WEST
COAST MON-TUE...ALTHOUGH THE TRACK SEEMS TO BE TRENDING FURTHER
OFFSHORE. IF IT TRACKS OFFSHORE...THIS WILL SEVERELY LIMIT PRECIP IN
THE SIERRA. BUT IF IT TRACKS RIGHT ALONG THE COAST...WE COULD SEE
YET ANOTHER ROUND OF SIERRA SNOW. EITHER WAY...CONTINUED COLD
TEMPERATURES AND ABOVE NORMAL CHANCES FOR PRECIP THROUGH THE LONG
TERM.  HOON

.AVIATION...

WINTER STORM CONTINUES TO AFFECT THE REGION TODAY WITH HEAVY SNOW
AND GUSTY WINDS LOWERING CIG/VIS TO IFR/LIFR THROUGH MUCH OF THE
DAY...ESPECIALLY FOR KTRK AND KTVL. HEAVY SNOW WILL CONTINUE THROUGH
THE DAY...WITH 12 TO 18 INCHES TOTAL FOR THE SIERRA TERMINALS
THROUGH THURSDAY MORNING.

WINDS WILL BLOW CONTINUOUSLY THROUGH THE EVENT...WITH GUSTS AROUND
30-35KT ALONG AND BEHIND THE COLD FRONT. THESE WINDS COMBINED WITH
HEAVY SNOWFALL WILL CREATE LOCALIZED WHITEOUT CONDITIONS AT KTRK AND
KTVL.

FOR KRNO...SOUTH WINDS WILL TURN TO THE WEST AS THE COLD FRONT
PUSHES THROUGH LATER THIS MORNING...AROUND 18Z AT KRNO. AS THE FRONT
COMES THROUGH...SNOW LEVELS WILL COME DOWN TO THE VALLEY FLOOR AND
SNOW WILL START TO ACCUMULATE AT KRNO. NOT REALLY EXPECTING HUGE
AMOUNTS...WITH 2 INCHES EXPECTED AT THE AIRPORT (POTENTIALLY UP TO 4
INCHES). WORST CONDITIONS WILL BE FROM BETWEEN 15Z-18Z ALONG AND
AHEAD OF THE COLD FRONT WITH BURSTS OF MODERATE SNOW TEMPORARILY
LOWERING VIS TO IFR AT TIMES. SHOWERS WILL CONTINUE THROUGH LATE
TONIGHT...WITH SOME ADDITIONAL LIGHT ACCUMULATIONS.  HOON
