AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
321 PM PST SAT DEC 18 2010

.SHORT TERM...
ONCE AGAIN THE PRIMARY CONCERN FOR THE FORECAST IS SNOW LEVELS AND
QPF. BUT WILL GET THE EASIER PART OF THE FORECAST OUT OF THE WAY
FIRST. WINDS NEVER REACHED WARNING CRITERIA OVER MOST OF THE AREA
JUST EAST OF THE SIERRA AND INTO MINERAL COUNTY TODAY ALTHOUGH
SOME GUSTS TO NEAR 55 MPH WERE RECORDED. PERIODS OF BLOW OVER PCPN
AND A SLIGHTLY WETTER AIRMASS WERE PARTLY TO BLAME. THERE SHOULD
BE A BRIEF PERIOD OF TIME THIS EVENING WITH GUSTY WINDS TO NEAR 45
MPH...BUT THESE WILL BE SHORT LIVED AND SHOULD END IN THE EVENING
AHEAD OF THE SPILL OVER PCPN. WILL HANDLE THIS WITH LOCALLY HIGHER
WORDING IN THE ZONES. HAVE ISSUED ANOTHER LAKE WIND ADVISORY FOR
PYRAMID SUNDAY. WINDS WILL GUST AHEAD OF THE COLD FRONT...BUT
SHOULD BE SHORT LIVED ENOUGH TO LOW ENOUGH TO PRECLUDE ISSUING A
WIND ADVISORY...BUT SOME AREAS WILL BE QUITE GUSTY EAST OF THE SIERRA.

NOW ON TO THE HARDER STUFF. SNOW LEVELS ROSE TO NEAR LAKE LEVEL OR
JUST ABOVE TODAY AND SHOULD REMAIN THERE THROUGH THE NIGHT.
PERSISTENT UPPER LOW IN THE NE PAC WILL REMAIN IN PLACE THROUGH
SUNDAY BEFORE STARTING TO EJECT LATE MONDAY. ANOTHER IMPULSE WAS
SEEN MOVING THROUGH THE BASE OF THE TROF ASSOCIATED WITH THE UPPER
LOW HEADING TOWARD THE NRN CA COAST LATE THIS AFTERNOON. THIS WILL
BE THE NEXT WEATHER MAKER TONIGHT. IT SHOULD TAP A TROPICAL PLUME
OF MOISTURE WITH PWATS NEAR 1.5 INCHES NEAR THE CA COAST. WARM AIR
AHEAD OF THIS IMPULSE WILL PUSH SNOW LEVELS EVEN HIGHER EAST OF
THE SIERRA BY LATE TONIGHT AND THESE WILL REMAIN HIGH THROUGH
SUNDAY. SNOW LEVELS COULD REACH NEAR 8500 FEET IN PARTS OF MONO
COUNTY THEN 7000 TO 7500 FEET EAST OF THE SIERRA AROUND
RENO/CARSON CITY. JET MOVES SOUTH TONIGHT AND SHOULD IMPACT THE
AREA BY EARLY SUNDAY WITH SPILL OVER PCPN BEGINNING EAST OF THE
SIERRA AFTER 12Z AND BECOMING HEAVY AT TIMES BY EARLY SUNDAY
AFTERNOON. THIS COULD RESULT IN SOME LOCALIZED FLOODING FROM THE
RENO/CARSON CITY AREA SOUTH TO NEAR MINDEN WITH SMALL STREAMS AND
URBAN AREAS FEELING THE LARGEST IMPACT. CONSIDERED A FLOOD WATCH
FOR THIS BUT THINK THE AREA AFFECTED WILL BE FAIRLY SMALL SO WILL
JUST HANDLE WITH AND ESF FOR NOW. IF ADDITIONAL HEAVY RAIN IS
EXPECTED SUBSEQUENT SHIFTS MAY NEED TO ISSUE A FLOOD WATCH.

COLD FRONT ASSOCIATED WITH THE SHORT WAVE MOVES SOUTH LATE SUNDAY.
HEAVIEST PCPN COULD OCCUR WITH THE FRONT. TEMPS/SNOW LEVELS WILL
DEFINITELY FALL BEHIND THE FRONT LATE SUNDAY AFTERNOON/SUNDAY
EVENING. SNOW LEVELS SHOULD REACH ALL VALLEY FLOORS BY LATE SUNDAY
EVENING. CURRENT WARNINGS FOR SNOW LOOK GOOD. ALTHOUGH SOME OF THE
LOWER SIERRA VALLEYS WILL SEE ONLY RAIN TONIGHT. HIGHER
ELEVATIONS COULD AGAIN RECEIVE MULTIPLE FEET OF SNOW TONIGHT AND
SUNDAY. HEAVIEST PCPN SHOULD FALL IN THE TAHOE AREA BETWEEN 06Z
TONIGHT 00Z MONDAY. SNOW LEVELS MAY LOWER IN THE HEAVIEST SNOW
WITH ACCUMULATIONS NEAR LAKE LEVEL TONIGHT. FARTHER SOUTH THE
HEAVIEST PCPN MAY FALL SUNDAY/SUNDAY EVENING. FOR NOW WILL LEAVE
MONO COUNTY WARNING ABOVE 7500 FEET BUT THIS LIKELY NEED TO BE
DROPPED TO THE VALLEY FLOORS BY SUNDAY NIGHT.

EVEN THOUGH PCPN THINS OUT MONDAY THE SIERRA WILL CONTINUE TO SEE
SNOW FALL OFF AN ON THROUGH MONDAY. WARNINGS WERE EXTENDED EARLIER
AND WITH COLDER AIR OVER THE REGION...SNOW RATIOS WILL BE HIGHER
FOR SUNDAY NIGHT INTO MONDAY. MLF

.LONG TERM...TUESDAY THROUGH SATURDAY...
IMPORTANT DISCREPANCIES (MAINLY SNOW LEVELS) STILL EXIST WITH THE
SYSTEM DUE IN FOR TUESDAY AND WEDNESDAY. HOWEVER...ONE THING THAT
SEEMS TO BE COMING IN LINE IS THE FACT THAT MODELS ARE TRENDING
TOWARDS KEEPING SEPARATE THE MOISTURE WITH THE INCOMING SYSTEM AND
SUBTROPICAL MOISTURE OVER SOUTHERN CALIFORNIA AND NEVADA. THEREFORE...
I HAVE EASED DOWN SNOW LEVELS AS THE SUBTROPICAL MOISTURE/WARMER
FLOW STAYS AWAY FROM OUR REGION.

AS FAR AS DETAILS TUESDAY AND WEDNESDAY...EXACTLY HOW THE SYSTEM COMES
IN WILL DETERMINE HOW LOW THE SNOW LEVELS WIND UP. THE COLD FRONT
SUNDAY NIGHT WILL DRIVE SNOW LEVELS TO NEAR OR BELOW ALL VALLEY
FLOORS. IF THE UPPER SYSTEM COMES IN FAR ENOUGH SOUTH THE LOW LEVEL
FLOW WILL BACK TO AN EASTERLY DIRECTION (WITH LOW PRESSURE FORMING
OFF THE NORTHERN CALIFORNIA COAST) IN THE BASIN AND ENCOURAGE
PRECIPITATION TO STAY SNOW DOWN TO NEAR ALL VALLEY FLOORS. AT THIS
TIME...THIS WOULD BE MOST LIKELY TUESDAY AND INTO TUESDAY EVENING AS
SOME WARM AIR ADVECTION WASHES OVER THE REGION AND INDUCES
ISOTHERMAL SOUNDING PROFILES ALOFT. WHILE ALL THIS IS POSSIBLE THE
NAM IS THE MOST BULLISH WITH THIS CONCEPT WITH LESS AGREEMENT AMONG
OTHER MODELS. STAY TUNED FOR DETAILS OF THE SNOW LEVELS FOR THE
LOWER VALLEYS TUESDAY AND WEDNESDAY.

IN ANY CASE...ANOTHER SHOT OF HEAVY SIERRA SNOW IS BECOMING LIKELY
WITH ALL MODELS SHOWING A GOOD SHOT OF PRECIPITATION TUESDAY NIGHT
AND WEDNESDAY MORNING AHEAD OF THE INCOMING TROUGH AXIS. ALSO...WITH
THE FLOW ALOFT BACKING TOWARDS SOUTHERLY IN THE MID LEVELS...MONO
AND ALPINE COUNTIES STAND TO RECEIVE THE HEFTIEST SNOWFALL AMOUNTS.

FOR THURSDAY AND INTO FRIDAY...MODELS ARE IN GOOD AGREEMENT WITH DRIER
CONDITIONS AS A SHORTWAVE RIDGE BUILDS INTO THE REGION AND THE
TROUGH EXITS TO THE EAST. MODELS SWING IN ANOTHER DEEP TROUGH ON
SATURDAY...BRINGING ANOTHER ROUND OF COLDER TEMPERATURES...
PRECIPITATION...AND GUSTY WINDS. THE TROUGH WILL CONTINUE TO IMPACT
THE REGION THROUGH THE WEEKEND AND THE BEGINNING OF NEXT WEEK.
SNYDER/LINDAMAN

.AVIATION...
FOR KTVL AND KTRK...PRECIPITATION SHOULD REMAIN RAIN ALTHOUGH SOME
BRIEF MIXING IN OF SNOW MAY STILL OCCUR THROUGH AROUND 01Z.
HOWEVER...INCREASING RAIN INTENSITY AFTER 06Z WILL KEEP VISIBILITIES
PREVAILING AOB 5SM...FALLING TO AOB 2SM BY ARND 12Z SUNDAY AS
PRECIPITATION MAXES OUT IN INTENSITY. RAIN WILL CHANGE TO SNOW BY
EARLY AFTERNOON SUNDAY FOR SUB-MINIMUM LANDING CIGS/VSBYS.

FOR KRNO...WINDS SHLD REMAIN FAIRLY UNREMARKABLE THROUGH SUNDAY
MORNING AS MOISTURE INHIBITS MIXING DOWN OF STRONGER WINDS ALOFT.
HOWEVER...SOUTH TO SOUTHWEST WINDS COULD GET QUITE GUSTY BY SUNDAY
AFTERNOON AS A STRONG SURFACE PRESSURE GRADIENT DEVELOPS. AS FAR AS
PRECIPITATION...ALL RAIN IS EXPECTED THRU FRONTAL PASSAGE SUNDAY
AFTERNOON. SNYDER
