AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
225 PM PDT SAT APR 10 2010

.SYNOPSIS...STRONG WINDS WILL VISIT THE FORECAST AREA SUNDAY
AFTERNOON...ESPECIALLY ACROSS SOUTHERN LANDER/EUREKA...AND WHITE
PINE AND NORTHERN NYE COUNTIES. THIS IS ALL DUE TO A LARGE AREA OF
LOW PRESSURE IN THE EASTERN PACIFIC THAT WILL SWING THROUGH THE
STATE BEGINNING TOMORROW THROUGH LATE MONDAY INTO TUESDAY.

&&

.SHORT TERM...TONIGHT THROUGH TUESDAY. MID AND HIGH LEVEL CLOUDS
CAN BE SEEN STREAMING NORTHEAST ACROSS THE STATE THIS
AFTERNOON...WITH THE SUN PEEKING THROUGH FROM TIME TO TIME.
24-HOUR TEMPERATURES CHANGES FROM YESTERDAY ARE QUITE NICE WITH
KWMC 12 DEGREES HIGHER THAN YESTERDAY AT THIS TIME...AND KEKO AND
KP68 BOTH BEING 14 DEGREES HIGHER THAN YESTERDAY. FURTHER WEST A
LARGE UPPER LEVEL TROUGH IS CLEARLY SEEN SPINNING OUT IN THE
EASTERN PACIFIC. THIS SYSTEM WILL BE OUR NEXT WEATHER PRODUCER
OVER THE NEXT SEVERAL DAYS.

FOR SUNDAY...BIGGEST IMPACT WILL BE A SUBSTANTIAL INCREASE IN
WINDS. MODEL GUIDANCE HAS BEEN ADVERTISING 90AGL WINDS 35-40 KNOTS
BEGINNING LATE SUNDAY MORNING...INCREASING TO 45 TO 50 KNOTS BY
THE AFTERNOON...WITH THE STRONGEST WINDS ACROSS THE CENTRAL PART
OF THE STATE. 700MB AND 850MB V-WIND ANOMALIES OF +3 TO +4
STANDARD DEVIATIONS HAVE BEEN FAIRLY CONSISTENT WITHIN THE LAST
TWO DAYS...COVERING A LARGE SWATH ACROSS CENTRAL NEVADA. 500 MB
WINDS WILL ALSO BE QUITE STRONG SUNDAY AND DEPENDING ON WHICH
MODEL...WILL BE ON THE ORDER OF 65-75 KNOTS ACROSS THE AREA OF
NORTHERN NYE AND WHITE PINE COUNTIES. FOR THESE REASONS WE HAVE
DECIDED TO ISSUE A HIGH WIND WATCH FOR SOUTHERN
LANDER/EUREKA...NORTHERN NYE AND WHITE PINE COUNTIES FROM NOON
SUNDAY UNTIL 800 PM. THERE ARE SEVERAL FLIES IN THE OINTMENT WHICH
MAKES A HIGH WIND WARNING NOT A SURE THING. FIRST QUESTION WILL BE HOW
HIGH WE WILL BE ABLE TO MIX TOMORROW AFTERNOON AND SECOND HOW MUCH
MID AND HIGH LEVEL CLOUD COVER WE WILL SEE THAT WILL INHIBIT
SURFACE MIXING. FINALLY...MODELS DO NOT SHOW THAT WE HAVE A VERY
GOOD SURFACE PRESSURE GRADIENT SETTING UP FOR TOMORROW AFTERNOON.
HENCE THE UNCERTAINTY AND IT MAY VERY WELL BE THAT ONLY A WIND
ADVISORY FOR THESE AREAS ARE NEEDED.

BY EARLY SUNDAY EVENING A FAIRLY DECENT COLD FRONT WILL CROSS
NORTHERN NEVADA. HALF WAY ACROSS THE STATE THE FRONT LOOKS TO
BECOME RATHER DISJOINTED...BUT THERE WILL BE SOME COLD AIR BEHIND
IT. ALSO...PRECIPITATION IS ANTICIPATED TO DEVELOP OVER WESTERN
HUMBOLDT COUNTY EARLY SUNDAY EVENING..SPREADING EASTWARD THROUGH
THE NIGHT INTO MONDAY. AMOUNTS DO NOT LOOK THAT IMPRESSIVE WITH
LESS THAN 0.10 INCHES OVER THE VALLEYS WITH HIGHER AMOUNTS IN THE
MOUNTAINS. DURING MONDAY AFTERNOON IMPULSES WITHIN THE MAIN TROUGH
SWING THROUGH AND POPS ARE IN THE CHANCE CATEGORY AS A RESULT.
WITH THE 500 MB COLD POOL...LOW-LEVEL LAPSE RATES BECOME
INCREASINGLY UNSTABLE...SO WE MAY SEE A QUICK HITTING BURST OF
RAIN/SNOW SHOWERS ACROSS THE AREA.

BY LATE TUESDAY AFTERNOON THE TROUGH WILL BEGIN TO MOVE EAST WITH
CHANCES OF PRECIPITATION ENDING FROM WEST TO EAST...WITH A WEST TO
EAST FLOW SETTING UP TEMPORARILY.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY. EXTENDED PERIOD WILL
BE DOMINATED BY BLOCKING FLOW ACROSS THE CONUS. THIS WILL LEAD TO
HIGH UNCERTAINTY AND LOW CONFIDENCE IN THE EXTENDED FORECAST OVER
THE NEXT WEEK. OVERALL TEMPS AND PRECIP WILL BE NEAR AVG DURING THIS
PERIOD.

DURING TUESDAY NIGHT THE DEEP WEST COAST TROUGH WILL PULL OFF TO THE
MIDWEST LEAVING IN ITS WAKE WEAK RIDGING. AS EARLY AS WEDNESDAY
LARGE DIFFERENCES BETWEEN THE GFS/ECMWF ARISE AS THE PROGRESSIVE GFS
BEGINS TO BRING IN THE NEXT 500MB TROUGH FROM THE NORTHWEST. THE
OPERATIONAL GFS IS AN OUTLIER AT THIS POINT DURING THE MID-WEEK
PERIOD...SO TRENDED TOWARDS THE ECMWF...WITH A BLEND OF CLIMO TEMPS
DUE TO OVERALL UNCERTAINTY. DURING THE DAY ON THURSDAY THE ECMWF
KEEPS A LARGE RIDGE OVER THE REGION..WITH WARM SOUTHERLY FLOW. HAVE
KEPT TEMPS TOWARDS NEAR CLIMO ON THURSDAY...BUT IF THE STRONGER
RIDGE SOLUTION PLAYS OUT...IT WILL BE WARMER THAN CURRENT
FORECAST. HAVE INCREASED CLOUDS AND POPS FROM FRIDAY THROUGH
SATURDAY...WITH THE POSSIBILITY OF A NEGATIVE TILTED TROUGH
BEGINNING TO AFFECT THE REGION FROM CALIFORNIA. THIS FEATURE COULD
DESTABILIZE THE ATMOSPHERE ENOUGH FOR SCATTERED AFTERNOON SHOWERS.
MORE OF THE SAME ON SATURDAY WITH THE ECMWF EVEN SHOWING THE
POSSIBILITY OF MONSOON MOISTURE FROM TEXAS REACHING THE
INTERMOUNTAIN WEST...DUE TO THE HIGHLY NEGATIVE TILTED TROUGH.
THIS IS A VERY LOW CONFIDENCE PATTERN EVOLUTION...BUT THE CHANCE
OF SCATTERED SHOWERS WILL CONTINUE INTO THE WEEKEND.

&&

.AVIATION...VFR VIS/CIG CONDITIONS EXPECTED OVER THE NEXT 24
HOURS...BUT WINDS WILL BE A LARGE IMPACT AFT 18Z TOMORROW. WINDS
WILL WEAKEN TONIGHT...AFT 03Z AS SURFACE MIXING ENDS. DURING THE DAY
TOMORROW AN APPROACHING COLD FRONT WILL BRING A STRONG JET OF LOW
LEVEL WINDS TO THE SILVER STATE. EXPECTING WIND GUSTS OUT OF THE
SOUTH...IN EXCESS OF 50KTS AT KELY...40KTS KTPH...35KTS KEKO/KWMC.
WINDS ARE EXPECTED TO INCREASE FROM 18-21Z AS DAYTIME HEATING MIXES
THE WINDS TO THE SURFACE...WITH THE HIGHER GUSTS PEAKING TOWARDS THE
END OF THE TAF PERIOD.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...
WIND ADVISORY FROM NOON TO 8 PM PDT SUNDAY FOR NORTHERN LANDER
COUNTY AND NORTHERN EUREKA COUNTY...RUBY MOUNTAINS/EAST HUMBOLDT
RANGE...SOUTHWEST AND SOUTH CENTRAL ELKO COUNTY.

HIGH WIND WATCH FROM SUNDAY AFTERNOON THROUGH SUNDAY EVENING FOR
NORTHERN NYE COUNTY...SOUTHERN LANDER COUNTY AND SOUTHERN EUREKA
COUNTY...WHITE PINE COUNTY.
