AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
304 PM PST FRI NOV 11 2011

.SYNOPSIS...A COLD FRONT WILL REACH NORTHERN NEVADA EARLY
TOMORROW MORNING. A PERIOD OF LIGHT SNOW AND GUSTY WINDS WILL
OCCUR ALONG THE COLD FRONT...WITH LIGHT SNOWFALL ACCUMULATIONS
EXPECTED ACROSS THE NORTH. AFTER PARTIAL CLEARING SATURDAY
EVENING...ANOTHER STORM WILL BRING LIGHT SNOWFALL SUNDAY MORNING.
DRIER AND WARMER WEATHER WILL RETURN FOR THE BEGINNING OF NEXT
WEEK.

&&

.SHORT TERM...TONIGHT THROUGH MONDAY. MID AND HIGH LEVEL MOISTURE
CONTINUE TO STREAM ACROSS THE CWA THIS EVENING...AS THE 500MB LOW
OFF THE CALI COAST CONTINUES TO ADVECT DEEP 600-300MB MOISTURE INTO
THE AREA. WATER VAPOR SATELLITE HAS A CLEARLY DEFINED 500MB VORT
MAX DIGGING OVER THE PUGET SOUND AT THIS HOUR. THIS MID-LEVEL
SHORTWAVE WILL QUICKLY DIG INTO IDAHO TONIGHT...BRINGING A SHARP
COLD FRONT INTO NORTHERN NV BY DAYBREAK. LATEST GUIDANCE HAS
TRENDED THE 500MB TROUGH SLIGHTLY FURTHER EAST...SO HAVE TRENDED
QPF DOWN A LITTLE...WITH THE HIGHEST SNOWFALL AMOUNTS STILL BEING
CONFINED TO NORTHERN ELKO COUNTY...WITH AMOUNTS QUICKLY
DIMINISHING SOUTH OF I-80. DIDN'T DOWNSCALE AS MUCH AS GUIDANCE IS
SUGGESTING...DUE TO AMBLE ANTECEDENT MOISTURE AHEAD OF THE
FRONT...WHICH THE MODELS HAVE BEEN UNDER-DOING OVER THE LAST
24HRS. THINKING IS STILL SIMILAR WITH TIMING AND A QUICK BURST OF
SNOW ALONG THE FRONT EARLY IN THE MORNING. HAVE TRENDED SNOW
LEVELS DOWN ABOUT 500FT...DUE TO THE FRONT COMING IN DURING THE
EARLY MORNING HOURS...WHICH WILL HELP COOL THE COLUMN. WITH THAT
SAID THERE COULD BE A BRIEF PERIOD OF RAIN AT THE ONSET BELOW
5500FT...BUT IT SHOULD QUICKLY TRANSITION OVER TO SNOW.

THE FRONT WILL QUICKLY PUSH THROUGH BY MIDDAY ON SATURDAY...WITH
BREEZY WESTERLY WINDS BEHIND THE FRONT. HAVE INCREASED THE
POTENTIAL FOR LEE SIDE DOWNSLOPE WINDS ACROSS ELKO COUNTY...BUT
GUIDANCE HAS BACKED OFF ADVISORY LEVEL WINDS. STILL FEEL THERE
WILL BE LOCALIZED GUSTS ON THE LEE-SIDE OF THE EAST HUMBOLDTS/RUBY
RANGES REACHING ADVISORY LEVELS.

PARTIAL CLEARING SATURDAY EVENING...BEFORE THE POLWARD EXIT REGION
OF A 130KT JET STREAK DIGS INTO NORTHERN NV EARLY SUNDAY MORNING.
THIS WILL BRING ANOTHER PERIOD OF LIGHT SNOW SUNDAY MORNING...BUT
ACCUMULATIONS WILL BE LIGHT ACROSS THE VALLEYS WITH MOSTLY LESS
THEN 1"...BUT THE MOUNTAINS COULD PICK UP ANOTHER 1-3". SNOW WILL
QUICKLY PUSH INTO CENTRAL NV BY MIDDAY...WITH PARTIAL CLEARING BY
LATE AFTERNOON. MID AND HIGH LEVEL CLOUDS WILL CONTINUE TO ADVECT
OVER THE REGION ON MONDAY...BUT NO PRECIP IS EXPECTED WITH HIGHS
MOSTLY IN THE 40S UNDER MARITIME POLAR NORTHWEST FLOW.

.LONG TERM...MONDAY NIGHT THROUGH NEXT FRIDAY. LONG WAVE TROUGH OVER
THE CENTRAL U.S. WILL KEEP DRY NORTHWEST FLOW OVER THE INTERIOR WEST
THROUGH WEDNESDAY NIGHT...WITH NEXT SHORT WAVE DROPPING OUT OF GULF
OF ALASKA BY LATE WEDNESDAY NIGHT/THURSDAY MORNING...HOWEVER THERE
ARE BEGINNING TO BE SOME TIMING AND STRENGTH DIFFERENCES BETWEEN THE
GFS AND EURO. THE GFS APPEARS MORE NEGATIVELY TILTED AND PERHAPS A
BIT MORE PROGRESSIVE. THE EURO LOOKS TO BE A BIT POSITIVE TILTED AND
SLOWER AND NOT QUITE AS DEEP. COMBO OF MODELS APPEARS TO BEST BET.
HAVE INCREASED POPS AND LOWERED SNOW LEVELS IN RESPONSE TO OFFICES'
THINKING WEST OF HERE...WHICH SEEM APPROPRIATE AT THIS TIME.
STILL...WE ARE LOOKING AT A WEEK AWAY SO CONFIDENCE IS STILL ON THE
IFFY SIDE. WILL KEEP AN EYE ON THINGS. IT COULD ALSO GET WINDY WITH
THIS EVENT. RAN LOCAL WIND PROCEDURE FOR THIS TIME FRAME AND SPEEDS
WERE WELL INTO ADVISORY CRITERIA...WITH LOCALES IN HIGH WIND WARNING
RANGE...SO LOWERED THEM TO JUST BELOW CRITERIA LEVELS...BUT STILL
GUSTY. AGAIN...STAY TUNED. BB

&&

.AVIATION...MID TO HIGH CLOUD SHIELD PUSHING ACROSS CENTRAL AND
NORTHERN NEVADA THROUGH TONIGHT...EXPECTING LOWERING OF CEILINGS
THROUGH TAF PERIOD BUT REMAINING VFR. SOME VCSH MAY OCCUR TONIGHT AT
ALL SITES...WITH -SHSN DEVELOPING TOWARD SUNRISE AT KTPH AND KWMC
AND A COUPLE HOURS LATER AT KELY AND KEKO. TEMPERATURES WILL BE LOW
ENOUGH FOR SOME SNOW TO STICK TO RUNWAYS. NOT EXPECTING LARGE
ACCUMULATIONS. WINDS MAY BE GUSTY IN THE MORNING IN KELY. BB

&&

.LKN WATCHES/WARNINGS/ADVISORIES...
NONE.
