AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
333 AM PDT FRI APR 2 2010

.SYNOPSIS...UNSETTLED WEATHER WILL CONTINUE TODAY ACROSS NORTHERN
NEVADA AS PACIFIC MOISTURE AND A COLD FRONT COMBINE TO BRING
STRONG GUSTY WINDS AND A CHANCE OF SNOW...ESPECIALLY IN NORTHERN
ELKO COUNTY. AFTER A BRIEF RESPITE...ANOTHER SYSTEM WILL BRING A
CHANCE FOR RAIN AND SNOW SHOWERS TO THE REGION SATURDAY AFTERNOON.
A BRIEF BREAK WILL BE POSSIBLE SUNDAY BUT THIS WILL BE SHORT LIVED
AS A MODERATE WINTER STORM IS POSSIBLE LATE SUNDAY NIGHT INTO
MONDAY. TEMPERATURES WILL REMAIN BELOW NORMAL FOR THIS TIME OF
YEAR.

&&

.SHORT TERM...TODAY THROUGH SUNDAY. SATELLITE/RADAR IMAGERY FROM
THIS MORNING SHOWS VARIABLE CLOUDINESS ACROSS THE AREA WITH A FEW
ISOLATED SNOW SHOWERS RIGHT NOW OVER SOUTHERN ELKO COUNTY. NO
ACCUMULATION IS ANTICIPATED FROM THESE SHOWERS...EXCEPT MAYBE A
HALF INCH OVER THE RUBIES.

FOR TODAY EXPECT A FAIRLY TIGHT PRESSURE GRADIENT TO DEVELOP
ACROSS NORTHERN NEVADA...BRINGING STRONG WEST TO SOUTHWEST WINDS
TO MUCH OF THE AREA. EARLIER SHIFT ISSUED A WIND ADVISORY FOR
HUMBOLDT COUNTY FOR LATER THIS AFTERNOON AND THIS EVENING...AND
THIS LOOKS GOOD. AS NOTED IN AN EARLIER DISCUSSION...WARMING
ALOFT MAY INHIBIT STRONG WINDS MIXING DOWN...THUS LIMITING THE
AREAL COVERAGE OF ADVISORY LEVEL WINDS. LATEST MODEL SOUNDINGS
CONTINUE TO POINT THIS OUT AND WE SEE NO REASON AT THIS TIME TO
DEVIATE FROM PREVIOUS LINE OF THINKING. STILL...COULD SEE LOCALLY
HIGHER WINDS (NEAR ADVISORY CRITERIA) ACROSS PORTIONS OF
ELKO...LANDER AND EUREKA COUNTIES BUT SHOULD NOT BE WIDESPREAD.
HAVE ALSO ADDED AREAS OF BLOWING DUST FOR PORTIONS OF THE WESTERN
ZONES...BUT THE START OF PRECIPITATION LATER THIS MORNING AND
AFTERNOON MAY HELP TO KEEP THE DUST DOWN.

PACIFIC MOISTURE WILL RIDE OVER THE WEAK SHORTWAVE RIDGE LATER
THIS MORNING AND AFTERNOON. 295K SURFACE CONTINUES TO SHOW WEAK
ISENTROPIC LIFT OVER THE NORTHER HALF OF THE COUNTY WARNING AREA SO
HAVE BUMPED UP POPS DURING THIS TIME FRAME. 110 KT WESTERLY UPPER
JET WILL EVENTUALLY PUSH ACROSS NORTHERN CALIFORNIA AND NEVADA
LATER THIS AFTERNOON. COUPLED WITH THIS WILL BE MODERATE TO STRONG
700 MB FRONTOGENESIS ACROSS THE NORTHERN PORTIONS OF THE STATE.
MODEL SOLUTIONS HAVE BEEN CONSISTENT IN THE PAST COUPLE OF RUNS
WITH THIS FEATURE. MODEL CROSS-SECTIONS DEPICT GOOD MOISTURE AND
PRECIPITATION EFFICIENCY...ALTHOUGH INSTABILITY DOES NOT LOOK TO BE
THE BEST...ESPECIALLY IN THE 600-500MB LAYER. HOWEVER...WITH THE
STRONG WINDS ALOFT...THERE IS AN UPSLOPE COMPONENT THAT MIGHT BE
ENOUGH TO PUNCH THROUGH THIS STABLE LAYER. THINKING THIS WILL
BRING LIGHT TO MODERATE SNOW TO NORTHERN ELKO COUNTY WITH
SIGNIFICANT BLOWING AND DRIFTING SNOW. THEREFORE...ISSUED A WINTER
WEATHER ADVISORY FOR THE AFOREMENTIONED AREA FOR THE LATER PERIOD
THIS AFTERNOON UNTIL SATURDAY MORNING. FOR MORE
INFORMATION...PLEASE SEE RNOWSWLKN.

ANOTHER BRIEF BREAK WILL BE HAD SATURDAY BEFORE ANOTHER WEAK
IMPULSE HEADS EAST ACROSS THE FORECAST AREA. SURFACE LOW PRESSURE
AND LOW LEVEL LIFT ACROSS THE EASTERN HALF OF THE FORECAST AREA
MAY BRING A CHANCE FOR ADVISORY LEVEL SNOW ACROSS WHITE PINE AND
SOUTHERN ELKO COUNTIES FOR SATURDAY NIGHT INTO SUNDAY. WILL NEED TO
KEEP AN EYE ON THIS FEATURE AND SEE HOW IT EVOLVES. ANOTHER BRIEF
BREAK WILL BE HAD SUNDAY MORNING AND AFTERNOON...WITH BELOW NORMAL
TEMPERATURES CONTINUING THROUGHOUT THE SHORT TERM PERIOD.

.LONG TERM...SUNDAY NIGHT THROUGH NEXT FRIDAY. PROGRESSIVE WEATHER
PATTERN TO CONTINUE IN THE EXTENDED WITH DEEP PACIFIC
TROUGH...TRANSITIONING TO RIDGING BY MID-WEEK. TEMPS WILL START OFF
THE PERIOD BELOW AVG...BEFORE REBOUNDING TO AVG BY MID-WEEK. PRECIP
WILL BE NEAR AVG.

TIMING DIFFERENCE FOR THE APPROACHING PACIFIC SHORTWAVE HAVE
IMPROVED IN LONG TERM GUIDANCE FOR SUNDAY NIGHT INTO
MONDAY...SURPRISINGLY WITH THE ECMWF SPEEDING UP 12HRS TO BETTER
ALIGN ITSELF WITH THE GFS/GEFS. SYSTEM LOOKS FAVORABLE FOR A
MODERATE SNOWFALL EVENT ACROSS EASTERN NV ONCE AGAIN...WITH A 2
STANDARD DEVIATION 500MB TROUGH...DIGGING INTO THE CALIFORNIA COAST.
AS OF NOW UPPER LEVEL JET DYNAMICS/MID-LEVEL TROUGH LOCATION...AND
700-500MB FGEN DYNAMICS ARE ALL FAVORABLE FOR A MODERATE QPF EVENT
SUNDAY NIGHT THROUGH MONDAY. FEEL THE GFS HAS HAD MUCH MORE
CONTINUITY THEN THE ECMWF WITH THIS FEATURE OVER THE PAST 3
DAYS...SO HAVE LEANED TOWARDS THIS SOLUTION IN THE FORECAST.
WIDESPREAD PRECIP LIFTS OUT MONDAY NIGHT...WITH FAVORABLE NW
OROGRAPHIC SNOW SHOWERS CONTINUING INTO TUESDAY MORNING. BELOW
NORMAL TEMPS AND SCATTERED MOUNTAIN SNOW SHOWERS FOR TUESDAY WITH
BROAD NW FLOW OVER THE CWA. IT WILL STAY DRY ACROSS HUMBOLDT COUNTY
AND MOST OF CENTRAL NV...WITH SOME PARTIAL CLEARING. BY WEDNESDAY
THE 500MB RIDGE AXIS BUILDS OVER THE AREA WITH MODERATING TEMPS TO
SEASONAL NORMS AND MOSTLY CLEAR SKIES. FAIR WEATHER CONTINUES INTO
THURSDAY WITH MID-LEVEL RIDGE AXIS AND SURFACE HIGH OVER THE GREAT
BASIN. BY THE END OF THE WEEK SW FLOW WILL INCREASE AHEAD OF THE
NEXT PACIFIC TROUGH DIGGING MOVING INTO THE PACIFIC NORTHWEST.

&&

.AVIATION...VFR CONDITIONS THIS MORNING...BEFORE CONDITIONS LOWER TO
MVFR ACROSS NORTHERN TAF SITES BY LATE AFTERNOON. THE SYSTEM WILL
APPROACH MOVE INTO THE REGION THIS AFTERNOON...WITH STRONG GUSTY SW
WINDS REACHING NEAR 40KTS AT KWMC AND NEAR 30KTS KEKO. NOT EXPECTING
ANY RESTRICTIONS IN VISIBILITY FROM DUST...DUE TO RECENT PRECIP
WETTING THE GROUND. RAIN AND MVFR CEILINGS ARE EXPECTED AT KWMC BY
20Z...WITH A RAIN/SNOW MIX AT KEKO...MOST LIKELY TRANSITIONING TO
ALL SNOW BY 03Z AS COLDER AIR MOVES IN. THIS COULD CAUSE A BRIEF
PERIOD OF VFR CONDITIONS AT KEKO FRIDAY EVENING.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...
WINTER WEATHER ADVISORY FROM 3 PM THIS AFTERNOON TO 5 AM PDT
SATURDAY FOR NORTHERN ELKO COUNTY.

WIND ADVISORY FROM 1 PM THIS AFTERNOON TO 7 PM PDT THIS EVENING
