AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
314 PM PDT MON OCT 3 2011

.SHORT TERM...
UPGRADED TO A WINTER STORM WARNING FOR THE HIGHER ELEVATIONS OF
THE LAKE TAHOE AND MONO COUNTY ZONES TUESDAY NIGHT (LATE) AND
WEDNESDAY. I ALSO DROPPED THE WATCH FOR THE LASSEN...PLUMAS..AND
SIERRA COUNTY ZONE.

A SPLITTING TROUGH ALONG THE WEST COAST WILL PROGRESS INLAND TO
THE SIERRA LATE TONIGHT AND TUESDAY MORNING. THE SYSTEM DOES HAVE
SOME FORCING IN THE FORM OF THE RIGHT ENTRANCE REGION OF AN UPPER
JET STREAK BUT NOT MUCH APPARENT LINKAGE TO THE LOW LEVELS EXCEPT
OVER CENTRAL NEVADA. THEREFORE...WHILE MID AND UPPER LEVEL MOISTURE
WILL INCREASE THE LOW LEVELS IN THE BASIN WILL ONLY SLOWLY MOISTEN
UP TONIGHT. ALSO...WINDS ALOFT ARE SOUTH TO SOUTH SOUTHWEST OVER
THE SIERRA WHICH SHOULD LIMIT OROGRAPHIC SPILLOVER. WITH ALL THIS
IN MIND...I HAVE REDUCED POPS TO SLIGHT CHANCE OR LOWER FOR MUCH
OF THE REGION OUTSIDE OF THE SIERRA AND ACROSS NORTHERN WASHOE
COUNTIES (MORE SOUTHWEST FLOW AND EASIER TO SPILLOVER WITH LOWER
RIDGES) FOR TONIGHT AND TUESDAY WITH THIS SYSTEM BEING MORE OF A
WIND PRODUCER IN THE BASIN THAN ANYTHING ELSE.

ATTENTION TURNS TO THE REAL MEAT AND POTATOES OF THE FORECAST FOR
TUESDAY NIGHT AND WEDNESDAY. LOW PRESSURE CURRENTLY JUST SOUTHEAST
OF THE ALEUTIANS WILL DIG TO NEAR THE NORTHERN CALIFORNIA AND
SOUTHERN OREGON COASTS TUESDAY EVENING. ALOFT...THIS WILL BRING A
100-120 KT JET STREAK TO NEAR SAN FRANCISCO. AT THE SURFACE...A
STRONG COLD FRONT WILL DRIVE INTO NORTHERN CALIFORNIA LATE TUESDAY
NIGHT AS LOW PRESSURE OCCLUDES OFF THE PACIFIC NORTHWEST COAST. AS
THE FRONT DRIVES INLAND WEDNESDAY GOOD OROGRAPHIC FLOW INTO THE
SIERRA AND SHARP FORCING ALONG THE FRONT IS EXPECTED TO BRING
AROUND AN INCH OF LIQUID EQUIVALENT PRECIP TO THE SIERRA AND
BETWEEN 0.25 AND 0.50 INCHES OF WATER TO PORTIONS OF WESTERN AND
NORTHWESTERN NEVADA LATE TUESDAY NIGHT AND WEDNESDAY MORNING.

AS THE ABOVE FORECAST DETAILS HAVE NOT CHANGED MUCH LATELY...CONFIDENCE
IN AN EARLY SEASON SNOWFALL FOR HIGHER ELEVATIONS HAS GROWN
CONSIDERABLY. THEREFORE...WE HAVE PULLED THE TRIGGER ON AN EARLY
SEASON CRITERIA (6" IN 12 HOURS ABOVE 7000 FEET) WINTER STORM
WARNING FOR THE HIGHER ELEVATIONS OF THE LAKE TAHOE REGION AND
MONO COUNTY FOR LATE TUESDAY NIGHT AND WEDNESDAY. GIVEN SNOW
LEVELS WILL BE RATHER HIGH UNTIL THE BULK OF PRECIP HAS ENDED...
THE LASSEN...PLUMAS...AND SIERRA COUNTIES ZONE DOES NOT LOOK TO
HAVE ENOUGH COVERAGE/AMOUNT OF SNOWFALL TO CAUSE TRAVEL ISSUES
OUTSIDE OF YUBA PASS WEDNESDAY. THEREFORE...THE WINTER STORM WATCH
HAS BEEN CANCELLED. HOWEVER...A LIGHT ACCUMULATION IS POSSIBLE
ABOVE 6000-6500 FEET WEDNESDAY MORNING AS PRECIPITATION TAPERS OFF
BEHIND THE COLD FRONT. SEE THE WINTER STATEMENTS FOR MORE SPECIFIC
DETAILS OF THE EXPECTED SNOWFALL IN THE SIERRA.

WEDNESDAY NIGHT AND THURSDAY...PRECIPITATION TAPERS TO SHOWERS AS
THE UPPER LOW CUTS OFF AND REMAINS OVER THE SOUTHWEST CONUS. A
SMALL IMPULSE IS STILL PROGGED TO COME THROUGH WEDNESDAY EVENING
FOR TAHOE SOUTH TO MONO COUNTY...SO HIGHER POPS WERE LINGERED
THERE WEDNESDAY NIGHT THAN ANYWHERE ELSE.

TEMPERATURE WISE...IT WILL REMAIN WELL BELOW AVERAGE THURSDAY
UNDER THE UPPER LOW WITH 50S IN THE BASIN AND 40S IN THE SIERRA
VALLEYS. SNYDER

.LONG TERM...FRIDAY THROUGH MONDAY...
UPPER LOW WILL CONTINUE TO MOVE SLOWLY EAST TO NEAR THE FOUR CORNERS
REGION WITH FLAT RIDGE DEVELOPING ACROSS CA-NV FRIDAY. THE LAST
REMNANT WRAP AROUND PRECIP ASSOCIATED WITH THIS LOW SHOULD BE OUT
OF W-CNTRL NV AFT 12Z...ALTHOUGH LOW-MID CLOUD COVERAGE COULD LINGER
INTO MUCH OF THE DAY EAST OF HWY 95. TEMPS WILL RECOVER ABOUT 10
DEGREES FROM THURSDAY BUT STILL REMAIN BELOW NORMAL WITH HIGHS IN
THE 60S FOR MOST LOWER ELEVATIONS.

FOR THIS WEEKEND...TEMPS WILL INCREASE A FEW MORE DEGREES...BUT
WEAKER MIXING AND LIMITED RISE IN 700 MB TEMPS WITH AREAS OF CIRRUS
WILL LIMIT THE MAGNITUDE OF THIS WARMING TREND.

BY NEXT MONDAY...THE GFS BEGINS TO AMPLIFY THE RIDGE OVER ERN CA-WRN
NV WHILE ECMWF BRINGS IN ANOTHER SHORTWAVE TO THE NWRN US WITH A
RISK OF LIGHT PRECIP IN NERN CA-NWRN NV. THE ENSEMBLE MEMBERS VARY
BETWEEN THESE TWO OPERATIONAL SOLUTIONS WITH THE AMPLITUDE OF THE
RIDGE. SINCE THE ECMWF HAS SHOWN A LITTLE MORE CONSISTENCY WITH THE
FLATTER RIDGE...WILL LEAVE IN THE LOW END SHOWER CHANCES IN FAR NWRN
NV AND NERN CA NORTH OF SUSANVILLE WHILE KEEPING OTHER AREAS DRY.
THIS SCENARIO WOULD ALSO PREVENT MUCH FURTHER RISE IN MAX TEMPS
ESPECIALLY IN THE NORTH SO TEMPS WERE ONLY NUDGED UP SLIGHTLY TO
NEAR SEASONAL NORMALS OF LOWER 70S IN THE WRN NV VALLEYS. MJD
&&

.AVIATION...
WINDS CONTINUE TO BE MAIN CONCERN THRU TUESDAY NIGHT WITH S-SW GUSTS
30-35 KTS AT KRNO/KMMH AND 25-30 KTS AT KTVL/KTRK...DIMINISHING BTWN
01-03Z THIS EVENING. LIGHTER WINDS ARE EXPECTED BEHIND PASSAGE OF
WEAKENING SPLIT TROF EARLY TUESDAY...BEFORE INCREASING AGAIN LATER
IN THE DAY WITH GUSTS 25-30 KT. THE STRONGEST WINDS ARE LIKELY TO
OCCUR TUES NIGHT BTWN 04-12Z AHEAD OF THE COLD FRONT PASSAGE WITH
POSSIBLE GUSTS 40-45 KT.

VFR CONDS WILL PREVAIL THRU TUES EVE WITH ONLY A 10-20 PERCENT
CHANCE OF -SHRA AFFECTING THE TERMINALS IN THE SIERRA THRU 06Z TUES
EVE...FOLLOWED BY WORSENING VSBY/CIGS FROM LATE TUES NGT THRU WED AM
WITH CONDS POSSIBLY BELOW LANDING MINS AS PRECIP CHANGES TO SNOW
BEFORE ENDING. FOR KRNO...VFR CONDS TO PREVAIL THRU MOST OF TUES NGT
THEN CIGS AND/OR VSBY MAY DROP TO MVFR AT TIMES FOR A FEW HOURS WED
AM WITHIN THE 12Z-18Z TIME RANGE AS BAND OF RAIN MOVES THRU WITH
