AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
340 PM PDT TUE OCT 13 2009

.SHORT TERM...
PRIMARY PROBLEM TODAY HAS BEEN AMOUNT OF PCPN AND SNOW LEVELS
ACROSS THE SIERRA. AND SNOW LEVELS WILL CONTINUE TO BE A PROBLEM
THROUGH THE EVENING AND OVERNIGHT AS 140KT JET PLOWS ACROSS
CENTRAL CA THROUGH THE EVENING AND OVERNIGHT. THIS JET IS FARTHER
NORTH THAN PREVIOUS MODEL FORECASTS HAD INDICATED...BUT NEWER
RUNS HAVE A BETTER POSITION ON THIS FEATURE...ALTHOUGH LATEST
SATELLITE IMAGERY AND RADAR RETURNS LEAD ME TO BELIEVE THE JET MAY
BE COMING IN JUST A BIT FARTHER SOUTH. RECENTLY HAVE SEEN CLOUD TOP
COOL ON IR SATELLITE IMAGERY FROM THE BAY AREA EASTWARD AS THIS
JET MAKES ITS WAY ONSHORE. SNOW LEVELS WERE KEPT LOWER TODAY BY
THE INTENSITY OF THE PCPN COMING INTO THE SIERRA AS DYNAMICS HAVE
OVERCOME THE WARMING THAT WAS EXPECTED WITH THE OVERALL SYSTEM.
THUS HAVE LOWERED SNOW LEVELS SOMEWHAT FROM PREVIOUS FORECAST FOR
THE EVENING HOURS. MOST INTENSE PCPN HAS SHIFTING JUST A BIT TO
THE SOUTH WITH MAMMOTH LAKES NOW RECEIVING SNOW BELOW 8000 FEET.
EXPECT THIS TO CONTINUE THROUGH THE EVENING SO HAVE ISSUE A
WINTER STORM WARNING ABOVE 75000 FEET FOR MONO COUNTY.

FARTHER NORTH PCPN RATES HAVE EASED RECENTLY AND SNOW LEVELS IN
THE TAHOE BASIN HOVER AROUND 8000 TO 8500 FEET. WITH ADDITIONAL
HEAVY PCPN EXPECTED LATER THIS EVENING WOULD ANTICIPATE THAT SNOW
LEVELS WILL FALL AGAIN IN THE TAHOE BASIN. MOST ACCUMULATIONS
SHOULD STAY ABOVE 7500 FEET IN THE TAHOE AREA SO FOR NOW WILL NOT
ISSUE ANY ADVISORIES/WARNINGS. HOWEVER...IF PCPN INTENSITY
INCREASES RAPIDLY MAY NEED ADDITIONAL ADVISORIES/WARNINGS FOR THE
TAHOE AREA. PCPN TOTALS IN THE SIERRA COULD REACH AS MUCH AS 6
INCHES IN SOME LOCATIONS WITH 2 TO 4 INCHES POSSIBLE AT LAKE LEVEL
IN THE TAHOE BASIN. THESE HIGHER PCPN TOTALS WOULD CORRESPOND TO 4
TO 5 FEET OF SNOW IN THE HIGHEST ELEVATIONS IN MONO COUNTY IN THE
HIGH SIERRA...BUT MOST LOCATIONS IN MONO COUNTY ABOVE 7500 FEET
SHOULD RECEIVE NO MORE THAT 2 FEET.

EAST OF THE SIERRA THE PRESENCE OF INSTABILITY AND THE STRONG JET
WILL EASILY ALLOW PCPN TO CONTINUE SPILLING OVER THIS EVENING.
WHILE PCPN AMOUNTS WILL BE MUCH LESS EAST OF THE SIERRA...SOME
WESTERN NV AND NE CA VALLEYS COULD PICK UP AS MUCH 1.5 INCHES OF
RAIN.

BEYOND TONIGHT THE JET STREAK/UPPER TROUGH COMBINATION MOVES EAST
WITH A CORRESPONDING DECREASE IN PCPN COVERAGE AND AMOUNTS. RIDGE
BEGINS TO BUILD BY LATE WEDNESDAY NIGHT INTO THURSDAY WITH A
CORRESPONDING RISE IN DAYTIME TEMPERATURES. MLF

WINDS...
THE THREAT OF A HIGH WIND EVENT REMAINS INTACT FOR TONIGHT AND
INTO WED MORNING. TO MAINTAIN CONTINUITY...THE START TIME OF THE
WARNINGS WAS KEPT AT 00Z...ALTHOUGH THE MOST LIKELY TIME PERIOD
FOR THE STRONGEST WIND IS LATER THIS EVENING AND OVERNIGHT. BY
06Z...BOTH THE NAM AND GFS CENTER THE UPPER JET CORE OF 140+ KT
OVER THE CNTRL SIERRA INCLUDING THE TAHOE BASIN AND MOST OF MONO
COUNTY. THE PRESENCE OF THIS JET CORE OVERHEAD LATER THIS EVENING
WILL BE ACCOMPANIED BY RAPID DRYING ALOFT AND SHUT DOWN MOST
PRECIP AWAY FROM THE SIERRA...ALLOWING FOR MORE EFFICIENT MIXING
OF WINDS DOWN TO LOWER ELEVATIONS. NAM MODEL SOUNDINGS CONTINUE TO
SHOW A RAPID DROP IN THE TROPOPAUSE LEVEL FROM 300 MB THRU 03Z TO
POSSIBLY AS LOW AS 500 MB DURING THE 06Z- 09Z TIME FRAME. THIS
TYPE OF TROPOPAUSE DROP IS FAVORABLE FOR PRODUCING A PERIOD OF
EXTREME WINDS WITH GUSTS OVER 130 MPH ON THE SIERRA RIDGES AND
ALSO OVER 100 MPH AT TIMES ON THE HIGHER PEAKS IN WRN NV. THE JET
CORE WILL PERSIST THRU 12Z THEN BEGIN TO WEAKEN AND LIFT NORTH
BTWN 12Z-15Z...KEEPING THE THREAT OF HIGH WIND GUSTS IN PLACE FOR
A FEW MORE HOURS. THEREFORE THE WARNINGS WERE EXTENDED THRU 15Z.

FARTHER NORTH IN NERN CA-NWRN NV...THE POSITION OF THE JET CORE
TONIGHT FOLLOWED BY WEAKENING AS IT MOVES NORTH WED MORNING IS LESS
FAVORABLE FOR HIGH WINDS...BUT AFTER THE RAIN DIMINISHES SOME GUSTS
REACHING ADVISORY CRITERIA ARE LIKELY SO WIND ADVISORIES WERE ADDED
TO THESE ZONES WITH THE VALID TIMES MATCHING THE EXISTING WARNINGS.

FOR THE TAHOE ZONE...THE LAKE WIND ADVISORY WILL DROP OUT AND THE
WARNING WILL STAND ALONE TO AVOID HEADLINE CONFUSION. CHOPPY LAKE
CONDITIONS WILL PERSIST THRU WEDNESDAY SO AFTER THE THREAT OF HIGH
WINDS END BY MID MORNING WEDNESDAY...A NEW LAKE WIND ADVISORY WOULD
LIKELY REPLACE OF THE WARNING FOR THE REST OF THE DAY. MJD

.LONG TERM...SATURDAY THROUGH TUESDAY...
NEXT WEEKEND STARTS OUT MILD WITH TEMPERATURES ABOVE NORMAL AND WEAK
SOUTHWEST FLOW ALOFT. SUNDAY BOTH THE DETERMINISTIC GFS AND EC BRING
A RATHER WEAK NEGATIVELY TILTED SHORTWAVE INTO THE WEST COAST AND
ACROSS THE WESTERN GREAT BASIN... EXITING THE REGION MONDAY. THE
GEFS ENSEMBLE SPREAD IN THE 500MB FLOW IS LOW AND THE PROBABILITY OF
.1 INCHES OF PRECIPITATION FROM 12Z MON-00Z TUE APPROACHES 50 PCT
FROM TAHOE NORTH INTO FAR NORTHWEST NV.  THE EC IS SHARPER WITH THE
TROUGH AND ALSO QUITE A BIT WETTER.  SUSPECT THAT THE GFS IS
UNDERDOING QPF AS IT BRINGS A DECENT NW-SE JET INTO THE REGION
SUNDAY NIGHT PUSHING IT NORTH ACROSS FAR NW NV INTO CENTRAL NV
MONDAY. THIS WOULD GENERATE DECENT SYNOPTIC LEVEL FORCING FOR
SHOWERS SUNDAY NIGHT AND MONDAY TAHOE NORTH.

FOR SUNDAY THROUGH MONDAY RETAINED CHANCE POPS MAINLY SIERRA NEAR
TAHOE NORTH AND ACROSS WESTERN NEVADA NORTH OF HIGHWAY 50. THE GFS
RIDGES UP MORE SHARPLY IN THE WAKE OF THIS SHORTWAVE MONDAY WHILE
THE EC RETAINS A MOIST ZONAL FLOW UNTIL TUESDAY. IF THE EC SOLUTION
IS CLOSER TO REALITY THEN WE WILL SEE SCATTERED SHOWERS ACROSS
LASSEN AND NORTHERN WASHOE COUNTIES THROUGH MONDAY NIGHT AS WELL.

TEMPERATURES WILL DROP TO NEAR OR SLIGHTLY BELOW NORMALS FOR THIS
TIME OF YEAR WITH THE TROUGH MONDAY AND TUESDAY. JAH

.AVIATION...
A MAJOR STORM SYSTEM WILL CONTINUE TO AFFECT THE SIERRA AND WESTERN
NEVADA TONIGHT THROUGH MIDDAY WEDNESDAY WITH HEAVY RAIN...MOUNTAIN

...TOTAL RAIN AND SNOWFALL AMOUNTS...
FOR THE EASTERN SIERRA...FROM LASSEN COUNTY SOUTHWARD TO MONO
COUNTY...2 TO 6 INCHES OF RAIN ARE LIKELY BY LATE TONIGHT. SEVERAL

WEDNESDAY MORNING AS PRECIPITATION BEGINS TO TAPER OFF.

SLICK ROADS AND PONDING OF WATER FROM MODERATE TO HEAVY RAIN WILL

OIL BUILDUP ON ROAD SURFACES DURING THE DRY WEATHER FROM THE PAST
COUPLE OF MONTHS WILL ALSO ADD TO THE SLICK CONDITIONS AS THE
