AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
230 PM PST SAT FEB 12 2011

.SHORT TERM...
MAJOR PATTERN CHANGE STILL ON TRACK AS COLD UPPER LOW DROPS SOUTH
FROM THE GULF OF ALASKA INTO THE EAST PACIFIC. THE GFS HAS TRENDED
IN LINE WITH THE SLIGHTLY MORE ELONGATED LONGWAVE FEATURE AS
ADVERTISED IN THE ECMWF AND THERE SEEMS TO BE A CONSENSUS TO KEEP
TROUGH AXIS ALONG 130W AND MAIN SURFACE COLD FRONT HANGING OVER
NORTHERN CA UNTIL VERY END OF PERIOD WHEN MAIN UPPER TROUGH BEGINS
TO ADVANCE INLAND. SO BEST SPILLOVER AND HEAVY SNOW POTENTIAL WITH
TROUGH/COLD FRONT WILL OCCUR JUST BEYOND THIS PERIOD (SEE LONG
TERM DISCUSSION BELOW). WIND WILL HAVE THE BIGGEST IMPACT ON THE
SHORT TERM. MAIN CHANGES WERE TO INCREASE WINDS FURTHER FOR VALLEY
LOCATIONS SUN NIGHT-TUE NIGHT...SLOW EASTWARD PROGRESSION OF
PRECIPITATION...AND RAISE TEMPS A FEW DEGREES IN THE BASIN AND
RANGE TUE. TEMPERATURES TO REMAIN WELL ABOVE CLIMATOLOGY DESPITE A
SLIGHT COOLING WITH FALLING HEIGHTS MON-TUE. LOWS/HIGHS WERE KEPT
ABOVE MOS GUIDANCE.

FOR TONIGHT AND SUNDAY...SHORTWAVE TROUGH BRUSHING BY TO THE NORTH
WILL KEEP WINDS UP ON RIDGES WHERE GUSTS HAVE BEEN HITTING 70 MPH
ALREADY THIS AFTERNOON. VALLEYS HAVE BEEN SLOW TO RESPOND BUT
SHOULD START TO SEE AN INCREASE IN WINDS AS WARMING AND MIXING
BRING DOWN SOME OF THE HIGHER WINDS AT RIDGE LEVEL. WILL CONTINUE
LAKE WIND ADVISORIES FOR WIND GUSTS 30-35 MPH AND INCREASING CHOP.
WINDS SHOULD RELAX A BIT ON SUNDAY AS WINDS ALOFT DECREASE SLIGHTLY.
LIKE TODAY...A FEW LOCATIONS COULD APPROACH RECORD TEMPERATURES. AS
OF THIS WRITING...THE TEMPERATURE AT THE RENO-TAHOE INTERNATIONAL
AIRPORT WAS 66 DEGREES WHICH IS JUST ONE DEGREE SHY OF THE OLD
RECORD. SLIGHTLY LESS MIXING POTENTIAL AND A HIGHER RECORD HIGH
TEMPERATURE OF 71 SUN WILL PROBABLY KEEP A RECORD FROM BEING REACHED
THERE ON SUN. HOWEVER A FEW LOCATIONS WILL BE CLOSE.

LULL IN WIND SUNDAY WILL BE SHORTLIVED AS TROUGH DIGS SOUTHWARD
AND WINDS ONCE AGAIN INCREASE ALOFT SUN NIGHT. MODELS CONTINUE TO
SHOW LEAD SHORTWAVE FEATURE EJECTING AND BECOMING ABSORBED BY MAIN
LONGWAVE TROUGH MON NIGHT. 700MB FLOW QUICKLY REBOUNDS TO 50-60KT BY
12Z MON WITH 12Z NAM BUFKIT SHOWING DECENT CRITICAL LAYER DEVELOPING
NEAR MT TOP BY MON AFTERNOON WITH SOME PRECIPITATION BANKING ON THE
WEST SLOPES OF THE SIERRA. INCREASING SURFACE PRESSURE GRADIENT WILL
BRING AN INCREASE IN WINDS TO THE TAHOE BASIN BY DAYBREAK AND TO
MANY OTHER AREAS BY LATE MORNING MON WITH THE POTENTIAL FOR HIGH
WINDS ESPECIALLY ALONG HIGHWAY 395 CORRIDOR. STRONG SURFACE GRADIENT
WILL PERSIST THROUGH MUCH OF THE REMAINDER OF THE SHORT TERM WITH 30
AGL WINDS 30-50KT. SO THERE IS HIGH CONFIDENCE THAT ADVISORY LEVEL
WINDS WILL BE QUITE PERSISTENT AND WIDESPREAD WITH PERIODS OF HIGHER
WINDS EMBEDDED WITHIN THIS LARGER AREA MON THROUGH TUE NIGHT. HAVE
DECIDED TO COVER AREA WITH HIGH WIND WATCH MON-TUE AND WAIT TIL
LATER SHIFTS TO DECIDE ON THE EXACT BREAKDOWN OF WIND RELATED
ELEMENTS. BLOWING DUST WAS ADDED TO MANY LOWER VALLEYS AS THE AREA
HAS SEEN LITTLE PRECIPITATION SINCE THE BEGINNING OF THE NEW YEAR.

OTHERWISE PRECIPITATION WILL BE MAINLY CONFINED TO THE IMMEDIATE
CREST AND FAR NORTHERN AREAS WHERE SOME SPILLOVER WILL LIKELY
OCCUR BY TUE-TUE NIGHT IN AREA OF INCREASING INSTABILITY NEAR
APPROACHING COLD FRONT AND STEEPENING LAPSE RATES ALOFT ASSOCIATED
WITH UPPER TROUGH. PRECIPITATION WILL BECOME QUITE HEAVY BEGINNING
TUESDAY AFTERNOON ACROSS FAR WESTERN LASSEN COUNTY WITH HEAVY QPF
AMOUNTS ALONG THE CREST OF THE TAHOE BASIN NORTHWARD INTO PLUMAS AND
WESTERN LASSEN COUNTY TUE NIGHT. SNOW LEVELS WILL BE FALLING IN
THESE AREAS SUCH THAT TRAVEL IMPACTS SHOULD BEGIN OVER HIGHER SIERRA
PASSES TUE AFTERNOON AND THROUGHOUT THE NORTHERN SIERRA AND
NORTHEAST CA TUE NIGHT. HOHMANN

.LONG TERM...WEDNESDAY THROUGH SATURDAY...
GUIDANCE CONTINUES TO BE CONSISTENT WITH TIMING OF COLD FRONT
PASSAGE ON WEDNESDAY...CLEARING NERN CA-NWRN NV IN THE MORNING THEN
ACROSS THE I-80 AND HWY 50 CORRIDORS AROUND MIDDAY-EARLY AFTN AND
THRU MINERAL AND ERN CHURCHILL COUNTY BY LATE AFTN. THE FORECAST MAX
TEMPS FROM HWY 50 NORTHWARD WILL LIKELY OCCUR EARLIER IN THE DAY
WITH FALLING TEMPS IN THE AFTERNOON...WHILE FARTHER SOUTH THE TEMPS
COULD PUSH ABOVE 50 DEGREES BEFORE THE FRONT PASSAGE.

SNOW WILL BE ONGOING OVER THE SIERRA CREST MAINLY NORTH OF I-80 BY
WED MORNING AND SPILLING ACROSS LASSEN AND NRN WASHOE COUNTIES.
ALTHOUGH QPF VALUES DECREASE FROM TAHOE SOUTH TO MONO COUNTY DURING
THE DAY...THE COLDER TEMPS WILL TRANSLATE TO HIGHER SNOW RATIOS SO
HEAVY SNOW ACCUMULATIONS ARE PROBABLE ACROSS THE SIERRA AND INTO
NERN CA. STRONG FORCING ALONG AND BEHIND THE COLD FRONT WILL FAVOR A
PERIOD OF ACCUMULATING SNOW IN LOWER ELEVATIONS OF WRN NV WED
AFTN...CONTINUING INTO THE EVENING SOUTH OF HWY 50.

COLD WEATHER WILL PREVAIL INTO NEXT WEEKEND AS ADDITIONAL SHORTWAVE
ENERGY REINFORCES THE TROF OVER THE WRN US...KEEPING SNOW LEVELS
DOWN TO ALL VALLEYS AND MAX TEMPS UNLIKELY TO SURPASS 40 DEGREES IN
AREAS THAT RECEIVE SNOW COVER. IF SUFFICIENT AMOUNTS OF SNOW REACH
THE HWY 95 CORRIDOR WITH THE WEDNESDAY SYSTEM...THEN MAX TEMPS WOULD
NEED TO BE LOWERED FURTHER IN THESE AREAS. BOTH THE GFS AND ECMWF
CONTINUE TO TRACK A VIGOROUS UPPER LOW ACROSS THE NRN HALF OF CA AND
INTO THE CNTRL SIERRA FOR THURS NGT-FRIDAY. ON THIS TRACK...ENHANCED
LIFT WITH DEFORMATION ZONE...LOW LEVEL EAST FLOW...AND COLD POOL
ALOFT WOULD LEAD TO A DECENT BAND OF SNOW FORMING NOT JUST IN THE
SIERRA BUT ALSO FAVORING MUCH OF WRN NV ESPECIALLY SOUTH OF I-80.
SINCE THE TRACK OF THIS SYSTEM COULD STILL VARY WITH SUBSEQUENT
MODEL RUNS...HAVE LIMITED THE LIKELY POPS TO THE SIERRA BUT TRENDED
UPWARD WITH SNOW CHANCES FOR MOST OF WRN NV.

THIS SYSTEM SHOULD CLEAR THE REGION FOR FRI NGT THRU SAT ALTHOUGH
UNSETTLED CONDITIONS WILL CONTINUE WITH COLD AIR ALOFT AND BROAD
CYCLONIC FLOW. ANOTHER WEAKER SHORTWAVE MAY ROTATE AROUND THE MEAN
TROF ALTHOUGH THE LATEST GUIDANCE FAVORS KEEPING THIS SYSTEM FARTHER
OFF THE COAST...SO WILL LIMIT SNOW SHOWER POPS TO SLGT CHC IN
VALLEYS AND LOWER END CHANCE FOR THE SIERRA. MIN TEMPS WILL BE QUITE
CHILLY EVEN WITH MOSTLY CLOUDY SKIES...BUT IF ENOUGH AREAS CLEAR OUT
TOWARD THE WEEKEND THE LOWS WOULD BE SEVERAL DEGREES COLDER. MJD
&&

.AVIATION...
VFR WITH NO MAJOR CONCERNS THRU SUNDAY. S-SW WIND GUSTS 25-30 KT
THRU 03Z THIS EVENING AND 20-25 KT SUN AFTN. GUSTY RIDGE LEVEL
WINDS WILL INHIBIT FOG FORMATION AT KTRK AND OTHER SHELTERED VALLEYS
FOR THE NEXT FEW NIGHTS. MUCH STRONGER WINDS WITH LEE SIDE MTN WAVES
AND ROTORS ARE EXPECTED ACROSS THE REGION FOR MONDAY. MJD
