AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE RENO NV
254 PM PST SAT DEC 15 2012

.SHORT TERM...
LIGHT WARM AIR ADVECTION SNOW IS MOVING INTO WESTERN NV AT THIS
TIME. MODELS IN AGREEMENT THIS WILL CONTINUE INTO THE EVENING
BEFORE WEAKENING. ANOTHER WAVE IS PRESENT IN THE FLOW WHICH WILL
INCREASE THE WARM AIR ADVECTION AGAIN TOMORROW AFTERNOON WITH SOME
LIGHT SNOW POSSIBLE NORTH OF I-80. AT BEST SNOW AMOUNTS WILL BE UP
TO 4 INCHES IN THE SIERRA WITH PERHAPS AN INCH POSSIBLE IN THE
LOWER VALLEYS OF WESTERN NEVADA AND NORTHEAST CALIFORNIA.

MODELS REMAIN IN DECENT AGREEMENT WITH THE MAIN THREAT THROUGH THE
SHORT TERM SUNDAY NIGHT INTO TUESDAY MORNING. THE MAIN DIFFERENCE
TODAY IS THAT THE MODELS ARE A BIT FASTER AND ALSO WETTER FOR
SUNDAY NIGHT. NOW THE MODELS HAVE THE STRONG 160+ KT JET STREAM
MOVING ONTO THE CA/OR BORDER SUNDAY EVENING. WITH PLENTY OF
MOISTURE STILL EMBEDDED IN THE FLOW, SNOW WILL LIKELY CONTINUE IN
THE SIERRA FROM TAHOE NORTHWARD AND MAY BECOME LOCALLY HEAVY
OVERNIGHT. HOWEVER, MOISTURE IS EXPECTED TO SHALLOW BY MONDAY
MORNING. IN ADDITION, SNOW LEVELS WILL RISE OFF THE VALLEY FLOORS,
POSSIBLY REACHING 5500-6000 FEET.

THE STRONG JET WILL REMAIN TO THE NORTH WITH STRONG WINDS ALOFT
CONTINUING INTO MONDAY. WINDS WILL INCREASE ACROSS THE SIERRA AND
WESTERN NEVADA AND WILL BECOME WINDY AT TIMES. RIGHT NOW, I ONLY
HAVE GUSTS TO 45 MPH, BUT THESE MAY NEED TO BE INCREASED AND A
WIND STATEMENT MAY BE NEEDED FOR PORTIONS OF WESTERN NV. WITH THE
MOISTURE SHALLOWER, THE PRECIP WILL BE LIGHTER AND MORE LIKELY
CONFINED TO AREAS ALONG THE SIERRA CREST AND 15 MILES TO THE EAST.

MONDAY NIGHT, THIS STRONG COLD FRONT WILL MOVE THROUGH WITH
RAPIDLY FALLING TEMPERATURES BEHIND THE FRONT. SNOW LEVELS WILL
ALSO FALL TO ALL VALLEY FLOORS BY TUESDAY MORNING. RIGHT NOW,
THERE IS STRONG FORCING ALONG THE FRONT WITH GOOD UPPER LEVEL JET
SUPPORT. HOWEVER, MODELS ARE SHOWING A LACK OF MOISTURE WITH
LITTLE IN THE WAY OF PRECIP ALONG THE FRONT ASIDE FROM THE GFS.
THE GFS IS WETTEST, BUT FOR NOW WILL LEAN TOWARDS ITS IDEAS WITH
MODERATE SNOW POSSIBLE IN THE SIERRA AND LIGHTER SNOWS INTO THE
WESTERN NEVADA VALLEY FLOORS. THE REASON I DO THIS IS THAT STRONG
FORCING WILL OFTEN OVERCOME A LACK OF MOISTURE. I WOULDN'T EXPECT
THE PRECIP TO BE HEAVY, BUT A FEW MORE INCHES IN THE SIERRA AND A
COUPLE INCHES ON THE WESTERN NEVADA VALLEYS IS CERTAINLY POSSIBLE.

OVERALL AMOUNTS IN THE SIERRA FOR THE 36 HOURS ENDING TUESDAY
MORNING LOOK TO BE A FOOT OR MORE NEAR THE SIERRA CREST WITH A FEW
INCHES AROUND LAKE TAHOE INTO WESTERN LASSEN COUNTY. ANY SNOW IN
WESTERN NEVADA WOULD FALL TUESDAY MORNING WITH THE FRONT, WITH
PERHAPS 1-3 INCHES OF SNOW IF IT ALL COMES TOGETHER RIGHT. THE
THINKING IS WE WILL LIKELY NEED WINTER WX ADVYS FOR THE SIERRA
DURING THIS PERIOD. AN ADVY MAY ALSO BE NECESSARY FOR WESTERN NV
IF THE GFS VERIFIES.

BEHIND THE FRONT, TEMPERATURES WILL BE COLD TUESDAY WITH HIGHS IN
THE 20S IN THE SIERRA AND 30S IN THE LOWER VALLEYS OF NORTHEAST CA
AND WESTERN NV. 700 TEMPS ARE FORECAST TO FALL AS LOWS AS -16 TO
-18 C ON ALL MODELS. WITH CLEARING SKIES EXPECTED TUESDAY NIGHT,
IT COULD BE THE COLDEST NIGHT OF THE SEASON SO FAR. ASSUMING
CLEAR SKIES, THERE WOULD BE QUITE A FEW BELOW ZERO READINGS IN THE
SIERRA AND WIDESPREAD SINGLE DIGITS IN WRN NV. ANY CLOUD COVER
WOULD KEEP OVERNIGHT LOWS WARMER. WALLMANN

.LONG TERM...WEDNESDAY THROUGH SATURDAY...
SHORTWAVE RIDGE SHOULD KEEP WEDNESDAY DRY WITH WIDESPREAD HIGH
CLOUDS, BUT MODEL GUIDANCE MADE A SIGNIFICANT REVERSAL TOWARD A
WETTER WEATHER PATTERN FROM THURSDAY AND INTO NEXT WEEKEND. BOTH
THE GFS AND ECMWF BRING A LARGE LOW PRESSURE CLOSER TO THE WEST
COAST, WITH THE DOWNSTREAM RIDGE AXIS NEAR OR EAST OF THE ROCKIES
THRU AT LEAST FRIDAY.

TEMPS ON WEDNESDAY WILL BARELY REACH FREEZING IN THE LOWER
ELEVATIONS AS FLAT RIDGE WILL KEEP INVERSION IN PLACE WITH THICK
MID-HIGH CLOUD DECK. IF SNOW COVER IS WIDESPREAD, TEMPS WOULD BE
EVEN LOWER ACROSS WESTERN NV.

FOR THURS-FRI, HAVE INCREASED POPS ESPECIALLY OVER THE SIERRA AND
NERN CA-NWRN NV TO NUDGE TOWARD THE LATEST GUIDANCE TREND. HOWEVER,
SINCE THE GUIDANCE HAS BEEN BACK AND FORTH WITH THE LONGWAVE
PATTERN, HAVE KEPT POPS IN THE CHANCE CATEGORY FOR NOW, WITH SLIGHT
CHANCE FOR PARTS OF WESTERN NV INCLUDING THE RENO ZONE AND ROUGHLY
FROM I-80 NORTHWARD ACROSS W-CNTRL NV. FOR THE MAJORITY OF THIS
EVENT, SNOW LEVELS LOOK TO BE CLOSE TO MOST VALLEY FLOORS ESPECIALLY
DURING THE NIGHT PERIODS. WINDS ARE ALSO MORE LIKELY TO INCREASE ON
THURSDAY, WITH STRONGER RIDGE WINDS POSSIBLY CONTINUING ALL THE WAY
INTO NEXT WEEKEND.

ON SATURDAY, THE MODEL GUIDANCE STILL SHOWS NOTABLE DIFFERENCES. THE
ECMWF IS DRIER WITH MOST MOISTURE PULLING BACK WEST OF THE SIERRA
INTO NORTH CENTRAL CA WITH WARMING 700 MB TEMPS, ALTHOUGH THIS
PULLBACK IS NOT AS FAR WEST COMPARED THE 00Z RUN. MEANWHILE THE GFS
PUSHES ANOTHER SHORTWAVE THROUGH WESTERN NV WITH ANOTHER SHOT OF
COLDER AIR. AS A STARTING POINT, HAVE SPLIT THE DIFFERENCE WITH
25-30 PERCENT POPS IN THE SIERRA BUT KEPT MOST OF WESTERN NV DRY
EXCEPT FOR THE FAR NORTHWEST. TEMPS WITH THIS WEATHER OUTLOOK WOULD
BE A BIT WARMER BUT STILL ONLY IN THE MID 40S FOR WESTERN NV AND
NEAR 40 FOR TAHOE.

MEDIUM RANGE GUIDANCE STILL INDICATES UNSETTLED WEATHER PATTERN
CONTINUING INTO THE CHRISTMAS HOLIDAY WITH ANOTHER POSSIBLE
SHORTWAVE PASSAGE SOMETIME BETWEEN SUNDAY AND CHRISTMAS DAY, AND
TEMPS LIKELY TO REMAIN BELOW NORMAL. MJD

&&

.AVIATION...
BAND OF SNOW WILL SPREAD QUICKLY ACROSS THE REGION FROM MID AFTN
THRU EARLY EVE WITH MAINLY MVFR CONDITIONS FOR KRNO, WITH OCNL IFR
POSSIBLE AT THE SIERRA TERMINALS. OVERALL SNOW ACCUMULATIONS WILL
BE LIGHT, BUT WITH TEMPS QUICKLY DROPPING BELOW FREEZING AFTER THE
SNOW BEGINS, MOST OF THE SNOW WHICH FALLS SHOULD ACCUMULATE ON
PAVED SURFACES WITH AN INCH OR TWO IN THE SIERRA, AND UP TO 1/2
INCH AT KRNO. FOR SUNDAY, MOST AREAS WILL IMPROVE TO VFR THRU MOST
OF THE DAY ALTHOUGH WIDESPREAD MID LEVEL CLOUD DECK IS EXPECTED.
LIGHT SNOW MAY RETURN TO KTVL/KTRK SUNDAY AFTERNOON, WITH
CONDITIONS CONTINUING TO WORSEN AT THESE SITES THRU SUN NIGHT WITH
CIGS OR VSBY LIKELY TO DROP BELOW LANDING MINIMUMS. MJD
