AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
300 PM PDT SUN MAY 8 2011

.SHORT TERM...
POTENTIALLY INTERESTING PCPN EVENT SETTING UP TONIGHT FOR WRN NV
AND THE CENTRAL/NRN SIERRA AS SOME MEASURABLE SNOWFALL IS
POSSIBLE IN VALLEY LOCATIONS LATE TONIGHT. WHILE THIS IS NOT
UNHEARD OF IN WRN NV IN MAY...IT IS MORE RARE THAN IN THE SIERRA.

FIRST SHORT WAVE SHOULD SWING EAST OF THE REGION THIS EVENING.
WILL HOLD ON TO A MENTION OF SHOWERS AND POSSIBLY EVEN A
THUNDERSTORM OVER FAR ERN SECTIONS OF THE CWA EARLY THIS EVENING
WHERE INSTABILITY IS THE GREATEST. LATER THIS EVENING ANOTHER
SHORT WAVE SHOULD BEGIN TO ROTATE SOUTH THROUGH THE BACK SIDE OF
THE UPPER LOW DROPPING INTO THE RGN. THIS IS THE POTENTIAL SNOW
MAKER FOR TONIGHT. WHILE NAM AND GFS HAVE DIFFERING TRACKS FOR
THIS SHORT WAVE BOTH DVLP PCPN BANDS OVER THE RGN BY LATE EVENING.
THE NAM IS QUICKER TO PUSH THIS THROUGH WITH MORE PCPN TO THE EAST
WHILE THE GFS IS A LITTLE SLOWER AND FARTHER WEST. IT SEEMS THE
GFS HANDLES THESE A BIT BETTER THAN THE NAM. HIGH RESOLUTION RAPID
REFRESH MODEL DVLPS A BAND OF PCPN OVER PLUMAS COUNTY BY 9/06 UTC
AND STARTS TO DROP IT SOUTHEAST AND EXPAND IT AS WELL. SO UPPED
POPS FOR NE CA EARLY THIS EVENING AND WRN NV INTO THE TAHOE AREA
OVERNIGHT. NOW THE QUESTION BECOMES THE SNOW LEVELS AND TEMPS.
GIVEN LACK OF PCPN FOR MUCH OF THE AREA THIS AFTERNOON THE SNOW
LEVELS HAVE RISEN A BIT. BUT WITH UPPER LOW SLIDING SOUTH THE SNOW
LEVELS WILL FALL TONIGHT. JUST HOW FAST THOUGH IS UP FOR DEBATE.
THINK THE SNOW LEVELS WILL STAY HIGH ENOUGH THIS EVENING TO LIMIT
ACCUMULATIONS OVER MUCH OF LASSEN COUNTY...THEN FALL OVERNIGHT AS
BAND MOVES SOUTH. CROSS SECTION USING THE GFS SHOWED BEST OMEGA
AFTER 9/06 UTC IN THE DENDRITIC GROWTH ZONE AND JUST ABOVE THAT
ZONE FROM ROUGHLY DOYLE SOUTHEAST INTO THE TRUCKEE MEADOWS THEN
SOUTH TO JUST EAST OF CARSON CITY. WHILE SNOW IS POSSIBLE DOWN TO
THE VALLEY FLOORS IN PLUMAS AND SIERRA COUNTY IT APPEARS THE FOCUS
WILL SHIFT JUST EAST TO THE 395 CORRIDOR FROM DOYLE TO NEAR RENO.
TEMPS AT THE LOWEST VALLEY FLOORS IN WRN NV MAY NOT SUPPORT
ACCUMULATING SNOWS FOR A VERY LONG PERIOD OF TIME THOUGH. BIGGEST
IMPACTS WOULD LIKELY BE ABOVE 5000 FT. SINCE IT IS EARLY MAY WE
ARE GOING TO USE LATE SEASON CRITERIA WHICH IS ROUGHLY HALF THE
NORMAL CRITERIA FOR SNOW FALL AND ISSUE AN ADVISORY FROM LATE
TONIGHT FOR SNOW IN NVZ003 WHERE AROUND AN INCH IS POSSIBLE AT THE
VALLEY FLOOR WITH AROUND 3 INCHES IN THE FOOTHILLS. THE HEAVIEST
SNOWS SHOULD FALL BETWEEN ABOUT 1 AM AND 4 AM. IT IS POSSIBLE THE
SRN 1/3 OF CAZ071 AND INTO CAZ072 WILL GET UP TO 3 INCHES...BUT
GIVEN THE LOWER ELEVATIONS AND HIGHER IMPACTS IN WRN NV WILL NOT
MENTION THOSE ZONES IN AN ADVISORY YET. IF CONDITIONS CHANGE THE
EVENING SHIFT CAN ISSUE FOR THOSE AREAS.

UPPER LOW SLIDES OVER THE RGN MONDAY AND TEMPS WILL BE COOLER WITH
HIGHS IN WRN NV VALLEYS STRUGGLING TO REACH THE MID 50S AND HIGHS
IN THE SIERRA IN THE 40S. UPSLOPE FLOW IN MONO COUNTY SHOULD AID
SNOW SHOWER DVLPMT OVER THE HIGHER ELEVATIONS THROUGH THE DAY.
SOME LINGERING SHOWERS MONDAY NIGHT INTO TUESDAY MORNING WITH
BETTER COVERAGE OVER MONO COUNTY AND THE FAR ERN CWA AS LOW BEGINS
TO LIFT OUT OF THE RGN.

SHORT WAVE RIDGE DVLPS TUESDAY AND SLIDES OVER THE RGN WEDNESDAY
WITH TEMPS REBOUNDING QUICKLY TO JUST BELOW AVERAGE TUESDAY AND
ABOVE AVERAGE WEDNESDAY. SHORT RANGE MODELS HINT AT CONVECTION
ACROSS THE FAR NW CWA WEDNESDAY AFTERNOON AS A WEAK IMPULSE PUSHES
INTO THE RIDGE. WILL LEAVE OUT MENTION OF PCPN FOR NOW BUT THIS
WILL NEED TO BE WATCHED AS INSTABILITY STARTS TO INCREASE OVER THE
RGN AHEAD OF AN APPROACHING TROF. MLF

.LONG TERM...THURSDAY THROUGH SUNDAY...
RIDGE OVER THE ERN GREAT BASIN WITH TROF IN THE ERN PACIFIC WILL
KEEP MODERATE SW FLOW ALOFT OVER THE REGION THURS-FRI WITH MAX TEMPS
A FEW DEGREES ABOVE NORMAL. THURSDAY STILL LOOKS TO BE DRY WITH SOME
AFTN CUMULUS FORMATION BUT TSTMS ARE UNLIKELY DUE TO LACK OF
SIGNIFICANT FORCING. BY FRIDAY...THE ECMWF REMAINS CONSISTENT WITH
NEGATIVE TILT SHORTWAVE PASSAGE PROVIDING ADDITIONAL LIFT AND
MOISTURE WITH INSTBY ALREADY IN PLACE SO MENTION OF TSTMS WILL BE
MAINTAINED. THE TWO MOST RECENT ECMWF RUNS HAVE GENERATED SOME
PRECIP FRI MORNING THEN PEAKING IN THE AFTERNOON...BEFORE LIFTING TO
THE NORTH DURING THE EVENING. OTHER GUIDANCE SOURCES DO NOT SHOW
MUCH QPF BUT ARE HINTING AT A SHORTWAVE PASSAGE...ALTHOUGH FARTHER
SOUTH AND EAST COMPARED TO THE ECMWF.

FOR NEXT WEEKEND...ANOTHER UPPER LOW IS PROJECTED TO APPROACH THE CA
COAST...WITH COOLER AIR MASS PUSHING INLAND AHEAD OF THE LOW CENTER.
A WEAK SHORTWAVE WITH LIMITED INSTBY COULD GENERATE A FEW LIGHT
SHOWERS SATURDAY BUT A MORE SIGNIFICANT MOISTURE PUSH IS POSSIBLE
LATE SAT NIGHT AND SUNDAY. BOTH THE ECMWF AND GFS SHOW 700 MB TEMPS
DROPPING TO NEAR -10 C SAT NIGHT THRU SUNDAY BRINGING ANOTHER THREAT
OF SNOW IN THE SIERRA AND TAHOE BASIN...AND POSSIBLY INTO FOOTHILL
LOCATIONS OF NERN CA AND FAR WRN NV. HAVE TRENDED TEMPS DOWN
ESPECIALLY FOR SUNDAY BUT IF THIS SYSTEM COMES IN AS ADVERTISED A
FURTHER DROP IN TEMPS WOULD BE NEEDED. MJD
&&

.AVIATION...
CONFIDENCE IS HIGH FOR BAND OF WET SNOW DEVELOPING LATE THIS EVENING
IN SRN LASSEN-ERN PLUMAS COUNTIES AND PUSHING SOUTH LATER TONIGHT
ACROSS THE TAF SITES. EACH AIRPORT CAN EXPECT A PERIOD OF IFR AND
POSSIBLE BRIEF LIFR CONDS WITHIN A 2-3 HR WINDOW AS INDICATED IN THE
TAFS. AT KRNO...RUNWAY SFC SHOULD REMAIN WET AS TEMPS STAY ABOVE
FREEZING...BUT A SLUSHY ACCUMULATION OF AN INCH OR TWO IS PROBABLE
AT KTRK/KTVL.

SCT -SHSN WILL CONTINUE THRU MONDAY BUT AT LOWER INTENSITY COMPARED
TO THE SNOW BAND LATE TONIGHT WITH NO ADDITIONAL ACCUMULATION ON
PAVED SURFACES DURING THE DAYTIME HOURS. AT KTVL/KTRK SOME MVFR AND
BRIEF IFR CIGS/VSBY WILL REMAIN POSSIBLE MAINLY BEFORE 19Z. AT
KRNO...MOST OF THE DAY SHOULD REMAIN VFR EXCEPT FOR BRIEF MVFR CIGS
OR VSBY WHEN PRECIP IS OCCURRING. HEAVIER SHOWERS MAY CONTAIN SNOW
PELLETS OR SMALL HAIL AND A FEW LIGHTNING STRIKES...WITH A 10-20
PERCENT PROBABILITY OF OCCURRENCE AT ANY OF THE TAF SITES. AFTER
00Z...MOST PRECIP WILL BE LIMITED TO UPSLOPE PORTIONS OF MONO
COUNTY. MJD
