AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
1258 AM PDT SUN MAR 22 2009

.SYNOPSIS...RAIN SHOWERS EARLY THIS MORNING WILL GIVE WAY TO
COOLER WEATHER AND SNOW SHOWERS ACROSS MUCH OF NEVADA. SIGNIFICANT
SNOWFALL WILL BE POSSIBLE IN THE HIGHER ELEVATIONS OF NORTHEASTERN
NEVADA THROUGH THIS AFTERNOON...WITH 1 TO 3 INCHES OF SNOW
POSSIBLE IN SOME OF THE VALLEY LOCATIONS. BREEZY TO LOCALLY WINDY
CONDITIONS ARE EXPECTED ACROSS PORTIONS OF THE GREAT BASIN THIS
AFTERNOON AND EVENING...WITH A DRYING TREND EARLY NEXT WEEK. &&

.SHORT TERM...TODAY THROUGH TUESDAY...BASE OF TROUGH APPROACHING
THE GREAT BASIN IS CURRENTLY CENTERED ALONG THE WEST COAST WITH
DIVERGENT SOUTHWESTERLY FLOW ALOFT OVER THE CWA. A COLD FRONT
CURRENTLY MOVING THROUGH WHITE PINE COUNTY IS TRIGGERING SCATTERED
THUNDERSTORMS...WITH SPOTTERS REPORTING PEA SIZED HAIL AND GUSTY
OUTFLOW WINDS. THIS FRONT WILL EXIT INTO UTAH LATE TONIGHT.
ISOLATED SHOWERS ARE ALSO POPPING UP OVER PORTIONS OF WESTERN
NEVADA AT THIS TIME.

WITH LITTLE BREAK BETWEEN EVENTS...A SECOND ROUND OF SHOWER
ACTIVITY WILL BEGIN OVER NORTH-CENTRAL AND CENTRAL NEVADA EARLY
THIS MORNING...AND SPREAD INTO EASTERN NEVADA LATER THIS MORNING.
SNOW LEVELS WILL BE LOWER WITH THIS SECOND SYSTEM...DROPPING TO
VALLEY FLOORS. MODELS CONTINUE TO SHOW AROUND 3/10THS OF AN INCH
OF QPF TO MUCH OF CENTRAL AND EASTERN NEVADA TODAY. ALTHOUGH SNOW
LEVELS WILL BE LOWERING TO VALLEY FLOORS THIS MORNING...SNOW
ACCUMULATIONS TO MOST VALLEY AREAS SHOULD BE LIMITED TO THE 1-3
INCH RANGE DUE IN PART TO WARM SURFACES...ALONG WITH THE INITIAL
PRECIPITATION BEING EITHER RAIN OR A RAIN AND SNOW MIX. LOW
ELEVATION AREAS NEAR THE WESTERN OR NORTHERN SLOPES OF HIGHER
TERRAIN COULD RECEIVE HIGHER SNOWFALL AMOUNTS HOWEVER. TERRAIN
ABOVE 6000 FEET IN ELEVATION COULD RECEIVE 3-7 INCHES OF SNOW WITH
THIS SYSTEM. WILL KEEP THE CURRENT WINTER WEATHER ADVISORIES IN
EFFECT. HEAVIEST SHOWER ACTIVITY SHOULD DIMINISH BY SUNSET AS THE
INSTABILITY DIMINISHES...HOWEVER SOME SHOWER ACTIVITY IS EXPECTED
TO CONTINUE ACROSS MUCH OF THE CENTRAL HIGHLANDS AND NORTHERN
MOUNTAINS THROUGH THE EVENING HOURS...DIMINISHING THROUGH MONDAY
MORNING.

THE OTHER MAIN CONCERN IN THE SHORT-TERM WILL BE WINDS ACROSS THE
REGION TODAY. AS TODAYS FRONT PUSHES EAST INTO UTAH THIS AFTERNOON
AND EVENING...NORTHWESTERLY WINDS WILL INCREASE OVER THE CWA. THE
AREAS OF GREATEST CONCERN ARE...THE WESTERN HALF OF NORTHERN NYE
COUNTY THIS AFTERNOON AND EVENING AS STRONG WINDS ALOFT ASSOCIATED
WITH THE BACK SIDE OF THE UPPER LEVEL JET MIX DOWN TO THE SURFACE
AND COMBINE WITH A MODERATE SURFACE GRADIENT...AND THE LEE SIDES
OF HIGHER TERRAIN DUE TO DOWNSLOPE WINDS...INCLUDING THE WENDOVER
AREA WHERE CHANNELING OF NW WINDS IS COMMON...THROUGH THE EVENING
AND INTO THE LATE NIGHT HOURS. WILL ISSUE A WIND ADVISORY FOR
NORTHERN NYE COUNTY IN EFFECT FROM 1 PM THROUGH 8 PM TODAY. WILL
HAVE TO MONITOR UPCOMING GUIDANCE AND RE-EVALUATE THE POSSIBLE NEED
FOR A WIND ADVISORY ACROSS NE NEVADA THIS EVENING INTO EARLY
MONDAY DUE TO DOWNSLOPE AND CHANNELING WINDS.

MUCH QUIETER WEATHER MONDAY AND TUESDAY AS HIGH PRESSURE BUILD
OVER THE EASTERN PACIFIC...ALLOWING A DRIER NORTHWESTERLY FLOW TO
DOMINATE ACROSS THE GREAT BASIN. COULD SEE A FEW SHOWERS ACROSS
THE MTS OF NORTHERN NEVADA TUESDAY.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY...GOOD GENERAL AGREEMENT
BETWEEN THE LONG RANGE MODELS THROUGH SATURDAY. HOWEVER THERE IS
STILL STRONG UNCERTAINTY ON THE AMOUNT OF ENERGY TO MOVE INTO THE
REGION. SHORT WAVE RIDGING WILL HOLD THROUGH TUESDAY
NIGHT...FOLLOWED BY AN EXTENDED PERIOD OF TROUGHING. THE GFS MODEL
IS SHOWING A SLOW-PROGRESSIVE TROUGH THAT RE-POSITIONS OVER THE FOUR
CORNERS AREA OF THE COUNTRY BY FRIDAY MORNING LEAVING BEHIND A
BUILDING RIDGE OVER THE FORECAST AREA. THE ECMWF ADVANCES THE TROUGH
AT NEARLY THE SAME PACE BUT SEEMS TO BE 6+ HRS AHEAD OF THE GFS
SOLUTION. THE DGEX IS VERY SIMILAR TO THE ECMWF THROUGH
WEDNESDAY..THEN SHOWS A MARKEDLY DIFFERENT SOLUTION. INSTEAD OF A
PROGRESSIVE TROUGH...THIS MODEL CARVES OUT A DEEPER LOW WITH
MULTIPLE WAVES DIVING SOUTH THROUGH THE BASE OF THE FEATURE. THE
SOLUTION GIVEN IS FOR THE MEAN TROUGH TO KICK EAST BEGINNING FRIDAY
NIGHT. THE DGEX SOLUTION IS LOOKING SUSPICIOUS ATTM SINCE IT CATCHES
UP WITH THE GFS AND ECMWF BY SATURDAY...PROPOSING THE MEAN TROUGH
PLACEMENT OUT OVER THE CENTRAL PART OF THE COUNTRY. ANTICIPATING
PRECIPITATION IN THIS SET-UP WILL BE DIFFICULT. HOWEVER WILL PUT
MAIN EMPHASIS ON THE WEDNESDAY SYSTEM WITH THE BEST CONSISTENCY/
CONFIDENCE RUN-TO-RUN. GFS SHOWS A STRONG COLD FRONT PUSHING INTO
THE GREAT BASIN WEDNESDAY AFTERNOON AND EVENING WITH 700MB TEMPS
LOWERING TO -16C...ALONG WITH A BAND OF SNOW PUSHING SOUTH AS FAR AS
EAST CENTRAL NEVADA. QPF VALUES ARE INDICATING MOUNTAIN SNOWFALL IN
EXCESS OF 6 INCHES FOR JARBIDGE AND RUBY MOUNTAINS AS WELL AS THE
HIGHER TERRAIN OF CENTRAL NEVADA. WILL ENHANCE POPS FOR THIS
PROPOSED EVENT. OTHERWISE SEE ONLY MINOR ADJUSTMENTS TO BE MADE. &&

.AVIATION...STRONG SOUTHERLY WINDS ARE EXPECTED ACROSS CNTRL NV
AGAIN TODAY AS A STRONG TROUGH OF LOW PRESSURE MOVES THROUGH THE
GREAT BASIN. AFTERNOON WIND GUSTS BETWEEN 35 TO 45 MPH ARE EXPECTED
THROUGH EARLY SUNDAY EVENING AND LOCALLY HIGHER GUSTS ARE POSSIBLE.
LIGHTER WINDS ARE EXPECTED FURTHER NORTH WITH WIND GUSTS GENERALLY
REACHING INTO THE 30S. KTPH APPEARS TO BE THE TAF SITE MOST
SUSCEPTIBLE TO THE STRONG WINDS. SHOWERS WILL BE MAINLY EAST OF
KWMC...AND THUNDERSTORMS SHOULD MAINLY BE CONFINED SOUTH OF HIGHWAY
50 IN CENTRAL NEVADA AGAIN TODAY. RAIN OR SNOW SHOWERS MAY BECOME
LOCALLY HEAVY AT TIMES WITH BRIEF EPISODES OF SMALL HAIL AND
VISIBILITY COULD BE REDUCED TO 3 MILES OR LESS IN CONVECTIVE CELLS.
&&
