AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
1049 PM PST THU NOV 17 2011

.SYNOPSIS...SOUTHWEST WINDS WILL REMAIN STRONG TONIGHT AS A
POTENT COLD FRONT APPROACHES NEVADA. THE COLD FRONT WILL SPREAD
ACCUMULATING SNOW...STRONG WINDS...AND BLOWING SNOW ACROSS
NORTHERN NEVADA FRIDAY AND FRIDAY NIGHT. THE SNOW WILL END BY
SATURDAY MORNING...LEAVING BEHIND MUCH COLDER TEMPERATURES
SATURDAY.

&&

.UPDATE...PRECIPITATION HAS BEGUN ACROSS PORTIONS OF NORTHERN
HUMBOLDT AND ELKO COUNTIES THIS EVENING WITH TEMPERATURES ABOUT 3
TO 6 DEGREES WARMER THAN EXPECTED IN THE GRIDDED FORECASTS. MODELS
ARE ONCE AGAIN SLOWING FORWARD PROGRESS OF ACTIVITY ALONG THE COLD
FRONT THIS MORNING. HAVE DECIDED TO PUSH BACK THE START TIME OF
IMPACT WINTER WEATHER ADVISORIES AND WINTER STORM WATCH IN THE
RUBY MOUNTAINS SLIGHTLY AS A RESULT BASED ON THIS INFORMATION.
PRODUCTS WILL BE SENT SHORTLY.

&&

.PREV DISCUSSION... /ISSUED AT 330 PM /

SHORT TERM...TONIGHT THROUGH SATURDAY. SW WINDS HAVE PUSHED
TEMPERATURES WELL ABOVE MID NOVEMBER NORMALS THIS AFTERNOON WITH
VALLEYS IN THE 50S TO NEAR 60. A PLEASANT AFTERNOON FOR NOVEMBER
STANDARDS...AND IT WILL MAKE THE WEATHER CHANGES EXPECTED TOMORROW
THAT MUCH MORE DRAMATIC.

TONIGHT...GRADIENTS TIGHTEN AHEAD OF APPROACHING COLD FRONT.
DESPITE THE NOCTURNAL TIMING LIMITING MIXING...OPTED TO ISSUE AN
ELEVATION-BASED WIND ADVISORY /ABOVE 5500 FEET/ THIS EVENING
THROUGH 4 AM FRIDAY. FELT COMPELLED TO ADDRESS THE WINDS TONIGHT
AS 700 MB WINDS CRANK UP 50-60 KTS ACROSS NORTHERN NEVADA BY
MORNING. MOST POPULATED VALLEYS SHOULD BE PROTECTED FROM THE WINDS
ALOFT BY SURFACE INVERSIONS...BUT CONFIDENT HIGHER TERRAIN WILL
SEE A VERY WINDY NIGHT WITH GUSTS OVER 50 MPH LIKELY. TRAVELERS
WILL BE MOST PRONE TO SUDDEN CHANGES IN WIND SPEED ON PASSES AND
SUMMITS THROUGH TONIGHT.

IMPRESSIVE COLD AIRMASS ON IR SATELLITE THIS AFTERNOON...OFF THE
BRITISH COLUMBIA/PAC NW COAST WITH PLENTIFUL COLD AIR CUMULUS
CONVECTION AND LIGHTNING. NOT CONFIDENT THAT ALL MODELS HAVE A
TRUE GRASP ON THE STRENGTH OF THIS INCOMING COLD AIRMASS. GFS HAS
BEEN MOST CONSISTENT AND SYNOPTICALLY LOGICAL OVER THE PAST
SEVERAL DAYS...SO FORECAST THROUGH FRIDAY NIGHT IS BASED HEAVILY
ON THIS MODEL. NAM CONTINUES TO TRY TO CATCH UP...JUST NOW
FORECASTING PRECIPITATION FOR THE FIRST TIME ON THE 12Z RUN TODAY.
FORECASTER CONFIDENCE ON THIS WINTER WEATHER EVENT OCCURRING IN
NEVADA TOMORROW IS VERY HIGH. HOWEVER...THE SPECIFIC FORECASTED
TIMING OF THE WINTER WEATHER IMPACTS AT ANY GIVEN LOCATION MAY
STILL CHANGE SOMEWHAT ONCE THE TROUGH ENTERS THE UPPER AIR RAOB
NETWORK THIS EVENING. 00Z NAM/GFS WILL BE CRITICAL IN THIS
REGARD...AND EVENING/MIDNIGHT SHIFTS WILL BE TASKED IN DETERMINING
EXACTLY WHEN THE SNOW/WIND COMBINATION WILL BE AT THEIR WORST AT
EACH LOCATION. FOR THIS PACKAGE...OPTED TO ISSUE AN IMPACT-BASED
WINTER WEATHER ADVISORY FOR SNOW AND BLOWING SNOW FOR MOST ZONES
/EXCLUDING NORTHERN NYE AND FAR EASTERN ELKO COUNTIES/ FROM 4 AM
FRIDAY THROUGH 4 AM SATURDAY. ALSO LEFT OUT WHITE PINE COUNTY FOR
NOW...AS IT APPEARS WITH THE GIVEN SHORTWAVE TRACK SNOW AMOUNTS
WILL BE SOMEWHAT LESS NEAR ELY. NONETHELESS...SNOW WILL COMBINE
WITH WIND TO PROVIDE IMPACTS IN WHITE PINE COUNTY...BUT PROBABLY
NOT UNTIL FRIDAY AFTERNOON. AGAIN...MIDNIGHT SHIFT WILL DETERMINE
EXACT TIMING.

FRIDAY...PRIMARY SHORTWAVE EXPECTED TO BE JUST ARRIVING ON THE
WEST COAST SUNRISE FRIDAY...WITH COLD FRONT STRENGTHENING ALONG THE
NORTHERN NEVADA BORDER. SHORTWAVE PUSHES INTO NW NEVADA BY 4 PM
FRIDAY...ALLOWING INTENSE COLD FRONT TO MAKE STEADY PROGRESS
SOUTHWARD ACROSS NORTHERN NEVADA. BEST ESTIMATE OF FRONTAL PASSAGE
TIMING IS NEAR WINNEMUCCA AROUND SUNRISE...ELKO/SPRING CREEK BY 10
AM - 1 PM...AND ENTERING WHITE PINE COUNTY AROUND 4 PM. IF MODEL
GUIDANCE IS HANDLING THE DIGGING SHORTWAVE CORRECTLY...THIS
APPROXIMATE TIMING WILL HOLD. SINCE THE MAIN ENERGY IS STILL OUT
IN THE DATA VOID PACIFIC...WOULD NOT BE SURPRISED IF THE 00Z
MODELS ALTER THE ABOVE TIMING SOMEWHAT. AT ANY RATE...COLD FRONT
WILL BE ACCOMPANIED BY VERY STRONG WINDS ALONG AND NEAR THE
FRONTAL BOUNDARY...GUSTING TO NEAR 50 MPH AT TIMES. THE WIND WILL
COMBINE WITH SNOW...HEAVY AT TIMES...DURING FRONTAL PASSAGE. THE
COMBINATION OF WIND AND SNOW WILL CREATE THE PRIMARY IMPACT FROM
THIS EVENT...BLOWING/DRIFTING SNOW AND REDUCED VISIBILITY. SNOW
IS EXPECTED TO FALL PRIMARILY BEHIND THE COLD FRONT IN THE MUCH
COLDER AIR...RESULTING IN POWDERY SNOW...PRONE TO BLOWING AND
DRIFTING. SNOWFALL IN THE VALLEYS WILL NOT BE EXCESSIVE...AVERAGING
1-3 INCHES. GIVEN THE COMBINATION WITH THE WIND...AND PRE-
THANKSGIVING TRAVEL ON FRIDAY...AN IMPACT-BASED ADVISORY IS
WARRANTED. BOTH AIR AND ROAD TEMPERATURES WILL FALL QUICKLY FRIDAY
AFTERNOON...ALLOWING SNOW TO BLOW AND ACCUMULATE EASILY. RESIDENTS
SHOULD BE AWARE THAT IT WILL GET PROGRESSIVELY COLDER DURING THE
DAY FRIDAY...AND PLAN ACCORDINGLY.

ELECTED TO ISSUE A WINTER STORM WATCH FOR NORTHERN ELKO COUNTY
/ZONE 031/ AND THE RUBY MOUNTAINS /ZONE 034/. SEVERAL MODELS
CONTINUE TO SUGGEST FORCING WILL BE STRONGEST ACROSS NORTHERN ELKO
COUNTY...WITH UPWARDS OF 6 INCHES POSSIBLE. AGAIN...WINDS WILL
CAUSE BLOWING AND DRIFTING. IN ADDITION...OROGRAPHICS GO TO WORK
BY FRIDAY EVENING IN THE MOUNTAINS OF ELKO COUNTY...WITH HEAVY
SNOW LIKELY ON NW FACING SLOPES. COVERED THIS WITH A WATCH FOR
NOW...MIDNIGHT SHIFT WILL DECIDE WHETHER TO UPGRADE.

FRIDAY EVENING...SNOW AND WIND WILL CONTINUE FOR MOST LOCATIONS AS
SHORTWAVE DIGS INTO CENTRAL NEVADA AND THE COLD FRONT EXITS WHITE
PINE COUNTY. MODEL GUIDANCE CONTINUES TO INDICATE THAT THIS TIME
FRAME /4 PM-10 PM FRIDAY EVENING/ WILL BE WHEN DENDRITIC
GROWTH/LIFT WILL BE MAXIMIZED AND SNOW PRODUCTION WILL BE MOST
EFFICIENT. ANY SNOW THAT FALLS WILL ACCUMULATE VERY EASILY AS
ATMOSPHERE GETS MUCH COLDER ALONG WITH NOCTURNAL TIMING. COLD NW
WINDS EXPECTED TO FORCE UPSLOPE SNOW TO CONTINUE THROUGH FRIDAY
EVENING...BEFORE TAPERING OFF TO SNOW SHOWERS AFTER MIDNIGHT.
ADVISORY EXPIRES AT 4 AM SATURDAY FOR NOW.

SATURDAY...FLOW QUICKLY GOES ZONAL AHEAD OF STRONG LOW OFF
NORTHERN CALIFORNIA COAST. LARGELY DRY FOR NORTHERN NEVADA WITH
ONLY A FEW MOUNTAIN SNOW SHOWERS. PRIMARY IMPACT SATURDAY WILL BE
THE COLD...WITH HIGH TEMPERATURES NEAR OR BELOW FREEZING. BT

LONG TERM...SATURDAY NIGHT THROUGH THANKSGIVING DAY. MODELS REMAIN
IN GOOD GENERAL AGREEMENT FOR THE BULK OF THE LONG TERM PERIOD.
COULD SEE SOME LINGERING LIGHT SHOWER ACTIVITY SATURDAY EVENING
ACROSS NORTHWESTERN HUMBOLDT COUNTY...AS WELL AS THE MOUNTAINS OF
EAST-CENTRAL NEVADA.

EXPECTING THE TROUGH OVER THE WESTERN U.S. TO SPLIT SUNDAY...DRIVING
MOST ENERGY SOUTH THROUGH CALIFORNIA WITH THE REMAINING ENERGY
GENERALLY TRACKING NORTH OF NEVADA. THE WEAK FLOW ALOFT OVER
NORTHERN AND CENTRAL NEVADA WILL RESULT IN MUCH CALMER WEATHER. BEST
CHANCE FOR A SHOWERS SUNDAY WILL BE IN EAST-CENTRAL NEVADA NEAR
GREAT BASIN PARK WHERE UP TO AN INCH OF ADDITIONAL SNOW IS POSSIBLE.
THE REMAINDER OF THE CWA SHOULD BE DRY.

TROUGH ENERGY PASSES WEST TO EAST...SOUTH OF NEVADA...INTO MONDAY
WITH CONTINUED DRY CONDITIONS OVER NORTHERN AND CENTRAL NEVADA.
EXPECT A SLIGHT WARMING TREND MONDAY THROUGH WEDNESDAY OF NEXT WEEK
AS A TROUGH DIGGING DOWN THE OFFSHORE WATERS OF THE WEST COAST TURNS
THE FLOW ALOFT OVER NEVADA TO A WARMER SOUTHWESTERLY PATTERN.

MODELS BEGIN TO DIVERGE NEXT WEDNESDAY NIGHT INTO THANKSGIVING WITH
RESPECT TO THE TIMING AND TRACK OF THE APPROACHING TROUGH. ECMWF
MODEL BEGINS TO SPLIT THE ENERGY AS IT NEARS THE CA COAST...LEAVING
NORTHERN AND CENTRAL NEVADA DRY THROUGH THANKSGIVING DAY WITH ONLY
SOME LIGHT SHOWERS OVER EXTREME NORTHERN NEVADA INTO THANKSGIVING
NIGHT. GFS ON THE OTHER HAND KEEPS THE TROUGH ENERGY MORE INTACT AS
IT MOVES ONSHORE OVER CALIFORNIA NEXT WEDNESDAY...WITH PRECIPITATION
MAKING ITS WAY INTO WESTERN NEVADA WEDNESDAY NIGHT. MAIN CHANGE TO
THE LONG TERM FORECAST WITH THIS LATEST PACKAGE WAS TO BACK OFF ON
POPS FOR THANKSGIVING DAY...IN GENERAL BLENDING THE ECMWF AND GFS
WITH ROUGHLY A 2 TO 1 RATIO. AT THIS TIME NO SIGNIFICANT CONCERNS
FOR TRAVEL ON THANKSGIVING...HOWEVER IF THE GFS MODEL ENDS UP BEING
MORE CORRECT IN BRINGING THE NEXT THROUGH STRAIGHT EAST ACROSS CA
INSTEAD OF SPLITTING THE ENERGY AROUND THE CWA AS THE EC
SUGGESTS...COULD SEE A MIX OF LIGHT RAIN AND SNOW TO MOST OF
NORTHERN AND CENTRAL NEVADA. JR

AVIATION...CEILINGS WILL LOWER ACROSS NORTHERN NEVADA TONIGHT WITH
SNOW SHOWERS BEING CONFINED TO MAINLY AREAS NORTH OF KWMC AND KEKO.
SNOW SHOWERS WILL CONTINUE TO SPREAD SOUTHEAST INTO CENTRAL NEVADA
ON FRIDAY. WINDS WILL BE GUSTY AHEAD OF...ALONG...AND BEHIND THE
APPROACHING FRONT. THE COMBINATION OF STRONG WINDS AND LIGHT TO
MODERATE SNOW WILL REDUCE VISIBILITIES SIGNIFICANTLY ALONG AND
BEHIND FRIDAYS FRONTAL PASSAGE. MAIN IMPACT AT KWMC AND KEKO WILL BE
LATE FRIDAY MORNING THROUGH THE EVENING...WITH KELY RECEIVING ITS
BIGGEST IMPACT LATE FRIDAY EVENING. EXACT TIMING OF THE FRONTAL
PASSAGE IS UNCERTAIN AT THIS TIME. HOPE TO HAVE A BETTER IDEA WITH
THE NEXT MODEL RUNS AND TONIGHT FORECAST PACKAGE. NEAR ZERO
VISIBILITY IS POSSIBLE IN BLOWING SNOW WITH THE FRONTAL PASSAGE.

LIGHTER SHOWERS AND GUSTY WINDS COULD CONTINUE AT EACH OF THOSE
THREE TAF SITES INTO SATURDAY MORNING...LINGERING LONGEST AT KELY.
NOT EXPECTING ANY SNOW AT KTPH...HOWEVER WINDS COULD BE GUSTY AT
TIMES. JR
