AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
255 PM PDT WED APR 23 2014

.SYNOPSIS...A BRIEF BREAK THROUGH THURSDAY BEFORE ANOTHER STORM
SYSTEM WILL BRING RAIN THURSDAY NIGHT AND FRIDAY INTO NORTHERN
NEVADA. COLDER AIR WILL MOVE IN BEHIND A COLD FRONT FRIDAY
AFTERNOON WITH RAIN CHANGING TO SNOW FRIDAY EVENING...ACCUMULATING
SNOWFALL IS LIKELY DOWN TO THE VALLEY FLOORS BY SATURDAY MORNING
WITH THE HEAVIEST SNOW EXPECTED ACROSS CENTRAL NEVADA.

&&

.SHORT TERM...TONIGHT THROUGH SATURDAY. INCREASING MID AND HIGH
LEVEL CLOUDS TONIGHT AS A TROUGH DIGS OFF THE EASTERN PACIFIC.

THURSDAY CLOUDS WILL CONTINUE TO INCREASE WITH SOME POCKETS OF
LIGHT PRECIPITATION ACROSS FAR NORTHERN NEVADA NORTH OF INTERSTATE
80. MODELS SHOW A BIT OF INSTABILITY ACROSS FAR NORTHERN NEVADA
WITH LI`S ZERO TO NEAR -1 SO INTRODUCED ISOLATED THUNDER IN
FORECAST. OTHERWISE THIS WILL BE THE WARMEST DAY OF THE SHORT TERM
WITH HIGHS IN THE 60S.

FRIDAY DEEP TROUGH WITH 500MB LOW FORMING NEAR CENTRAL CALIFORNIA
WILL DIG TOWARDS THE GREAT BASIN THIS WILL CREATE A STRONG SURFACE
LOW PRESSURE ACROSS SOUTHERN NEVADA CREATING FGEN FROM SOUTHERN
ELKO COUNTY TO CENTRAL NEVADA WHERE A SWATH OF QPF IS FORECASTED
BY ALL THE MODELS WITH DECENT RAINFALL EXPECTED FRIDAY WITH .10"
TO .25" COMMON ACROSS THE AREA WITH SOME AREAS NEAR A HALF INCH.
SOME INSTABILITY WITH STRONG DYNAMICS AND DIFFLUENT FLOW ACROSS
THE REGION SO MENTIONED ISOLD THUNDER BUT HARD TO PIN POINT EXACT
LOCATION AT THIS POINT. WINDS WILL ALSO BE GUSTY AROUND WHITE PINE
AND NORTHEASTERN NYE COUNTY FRIDAY AFTERNOON WITH 700MB WIND
STANDARD DEVIATION OF 2 TO 3 AND 90 AGL WINDS OF 30 TO 35 KNOTS. A
WIND ADVISORY MAY BE NEEDED FOR THESE TWO ZONES.

FRIDAY NIGHT AND SATURDAY. TEMPS WILL DROP BEHIND COLD FRONT WITH
700MB TEMPS DROPPING TO -6 TO -8 FRIDAY NIGHT THROUGH SATURDAY
MORNING AS 542MB LOW DIPS NEAR SOUTHERN NEVADA. FGEN LOOKS FAIRLY
DECENT FROM RUBY MOUNTAINS TO CENTRAL NEVADA SO EXPECT A GOOD .25"
TO .50" OF QPF OR BETTER IN VALLEYS THROUGH SATURDAY MORNING
TRANSLATING TO DECENT SNOWFALL OF 5 TO 8 INCHES IN MANY CENTRAL
NEVADA VALLEYS ESPECIALLY AREAS NEAR AUSTIN...EUREKA AND ELY.
ISSUED A WINTER STORM WATCH FOR THIS POTENTIAL SNOWFALL. SATURDAY
AFTERNOON THE LOW KICKS EAST WITH LINGERING SNOW SHOWERS WITH
UNSTABLE COLD AIR IN THE AREA.

.LONG TERM...SATURDAY NIGHT THROUGH NEXT WEDNESDAY.  500MB PATTERN
ACROSS THE WESTERN CONUS WILL TRANSFER FROM PROGRESSIVE NORTHWEST
FLOW ALOFT TO AMPLIFIED RIDGING BY THE BEGINNING OF NEXT WEEK.  THIS
WILL LEAD TO QUITE...WARM...AND DRY WEATHER NEXT WEEK.  FORECAST
CONFIDENCE IS ABOVE AVERAGE WITH STRONG RIDGING BEING PROGGED BY ALL
GUIDANCE AND THEIR RESPECTED ENSEMBLE MEANS NEXT WEEK. PRECIPITATION
WILL RUN BELOW AVERAGE AND TEMPS RUN NEAR AVERAGE FOR THIS PERIOD.

SUNDAY...WILL BE THE ONLY DAY DURING THE EXTENDED WITH A CHANCE FOR
PRECIPITATION AS A WEAK AND PROGRESSIVE 500MB SHORTWAVE TRAVERSES
ACROSS NORTHERN NEVADA.  THIS FEATURE WILL COINCIDE WITH MAX DAYTIME
HEATING...THUS LIFTED INDEX VALUES WILL RUN BELOW ZERO NORTH OF
HIGHWAY 50 ON SUNDAY AFTERNOON.  THIS SHOULD LEAD TO A MIX OF
RAIN/SNOW SHOWERS ACROSS VALLEY FLOORS WITH SNOW SHOWERS IN THE
MOUNTAINS.  A FEW GRAUPEL SHOWERS WILL ALSO BE POSSIBLE...WHICH IS A
FAVORITE APRIL TRADITION ACROSS THE HIGH DESERT OF NEVADA.

MONDAY THROUGH WEDNESDAY...MONDAY WILL REMAIN COOL AS NORTHWEST FLOW
CONTINUES OVER THE REGION...BUT IT WILL MOST LIKELY BE DRY WITH SOME
FAIR WEATHER STRATO-CUMULUS CLOUDS. TUESDAY INTO WEDNESDAY TEMPS
WILL BE ON THE REBOUND AS HEIGHTS RAPIDLY INCREASE OVER THE PACIFIC
COAST...DUE TO AN AMPLIFYING 500MB RIDGE AXIS. EXPECT HIGHS TO REACH
BACK INTO THE 70S BY WEDNESDAY UNDER CLEAR SKIES.

&&

.AVIATION...VFR CONDITIONS EXPECTED AT ALL TAF TERMINALS THIS
AFTERNOON THROUGH THE NIGHT WITH LIGHT WESTERLY TO NORTHWESTERLY
WINDS. CIGS SHOULD REMAIN AROUND 6K THROUGH THE AFTERNOON ACROSS THE
NORTH AS PACIFIC MOISTURE CONTINUES TO STREAM INTO THE REGION.
WEATHER WILL BECOME UNSETTLED BY FRIDAY ONCE AGAIN WITH THE NEXT
PACIFIC STORM EXPECTED TO IMPACT THE REGION.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...

205 AM PDT WED APR 23 2014

.SYNOPSIS...AFTER A BRIEF BREAK IN THE ACTION...A LOW PRESSURE
SYSTEM WILL SLOWLY MOVE THROUGH THE SILVER STATE. UNSETTLED
WEATHER WILL BEGIN TO AFFECT NORTHERN NEVADA THURSDAY...THEN
SHOWERS WILL SPREAD TO ALL OF NORTHERN AND CENTRAL NEVADA BY
FRIDAY. SOME VALLEY SNOW ACCUMULATIONS ARE POSSIBLE OVER THE
WEEKEND AND IMPROVING CONDITIONS ARE EXPECTED BY THE BEGINNING OF
NEXT WEEK.

&&

.SHORT TERM...TODAY THROUGH FRIDAY. A LITTLE COOLER THIS
MORNING...TEMPERATURES APPROACHING FREEZING. SATELLITE IMAGERY
SHOWS SOME LINGERING CLOUDS OVER EASTERN NEVADA BUT SHOWER
ACTIVITY HAS MOVED EAST TO NORTHERN UTAH. THE NEGATIVE TILT OF THE
EXITING TROUGH HAS LEFT A NORTHWEST FLOW ALOFT OF THE GREAT BASIN.
AS A SHORT WAVE RIDGE ENTERS THE PACIFIC COASTAL REGION...THERE IS
A SUBSTANTIALLY DENSE MID TO HIGH CLOUD DECK OVER RENO MOVING
TOWARDS THE SOUTHERN PART OF THE LKN CWFA. THUS CLEARING WILL NOT
OCCUR DESPITE THE IMPROVING CONDITIONS OVERALL. THE UPPER FLOW
PATTERN IS DEPICTED SIMILARLY BY THE MODELS HOWEVER THEY ARE STILL
HAVING DIFFICULTY WITH TIMING AND AMOUNT OF PRECIPITATION WITH THE
NEXT WEATHER SYSTEM THIS WEEK.

TODAY THROUGH THURSDAY. WEAK HIGH PRESSURE WILL MOVE OVER THE
STATE. THE LOW AMPLITUDE OF THE RIDGE PATTERN WILL ALLOW DIRT TO
CONTINUE TO STREAM ACROSS NORTHERN NEVADA...THUS CANNOT RULE OUT
SOME LIGHT SHOWERS MAINLY NORTH OF INTERSTATE 80. SNOW
ACCUMULATION IN THE VALLEYS IS NOT EXPECTED. HIGH TEMPERATURES
WILL GENERALLY RANGE FROM THE MID 40S TO THE MID 50S TODAY...AND
REACH INTO THE 60S WIDESPREAD THURSDAY. LOW TEMPERATURES WILL
RANGE FROM THE MID 20S TO THE MID 30S.

THURSDAY NIGHT THROUGH FRIDAY. A STRONG LOW PRESSURE SYSTEM WILL
DROP DOWN ALONG THE CALIFORNIA COAST. DESPITE THE ERRATIC TIMING
DIFFERENCES OF PRECIPITATION ONSET...THE GENERAL CONSENSUS IS FOR
A SUBSTANTIAL SLUG OF PACIFIC MOISTURE TO BE SCOOPED UP AND SLUNG
OVER THE STATE BY THE TIME THE UPPER LOW RE-CENTERS NEAR SAN
FRANCISCO AT THE END OF THE DAY FRIDAY. STRONG DIFFLUENCE ALOFT IS
DEPICTED OVER NORTHERN NEVADA AND MODEL QPF IS SIGNIFICANT. AN
EXTREMELY BROAD 80 KT JET FIELD WILL CROSS OVER THE STATE WHICH
WILL ENHANCE PROBABILITY OF CONVECTION OVER A WIDE AREA. THUNDERSTORMS
ARE POSSIBLE. THROUGH FRIDAY AFTERNOON...SNOW LEVELS SHOULD GENERALLY
HOLD ABOVE 5500 FEET HOWEVER A BRIEF BLAST OF SNOW BELOW THAT
LEVEL IS POSSIBLE BY LATE AFTERNOON AS A COLD FRONT DEVELOPS.
MOUNTAINS SHOULD BENEFIT GREATLY AND IMPACTS ON HIGHWAY OVERPASSES
SHOULD BE BRIEF. HIGH TEMPERATURES WILL GENERALLY BE IN THE 50S
ACROSS NORTHERN NEVADA...OCCURRING EARLY IN THE DAY. LOW
TEMPERATURES WILL RANGE FROM THE 30S TO AROUND 40 DEGREES. HIGH
TEMPERATURES WILL BE IN THE 60S SOUTH OF HIGHWAY 50.

.LONG TERM...FRIDAY NIGHT THROUGH NEXT TUESDAY.

A STRONG PACIFIC STORM SYSTEM WILL BRING ACCUMULATING SNOW TO MUCH
OF EASTERN NEVADA FRIDAY NIGHT AND SATURDAY MORNING. UNSEASONABLY
COLD SATURDAY, FOLLOWED BY A WARMING TREND SUNDAY THROUGH TUESDAY.

00Z GFS/ECMWF IN GOOD AGREEMENT FORECASTING AN INTENSE UPPER LOW TO
DIVE DOWN THE CALIFORNIA COASTLINE FRIDAY EVENING, WITH A
WELL-DEFINED DEFORMATION AXIS PRODUCING SIGNIFICANT RAIN/SNOW ACROSS
THE SE ZONES. ECMWF SUGGESTS HEAVY WET SNOW MAY FALL FRIDAY EVENING
INTO SATURDAY MORNING ACROSS SOUTHERN ELKO, WHITE PINE, SE EUREKA
AND NORTHERN NYE COUNTIES. FRONTOGENESIS FORCING FROM GFS MIRRORS
THESE SAME ZONES. INCREASED RAIN/SNOW COVERAGE SIGNIFICANTLY INTO
THE LIKELY CATEGORY FOR MUCH OF EASTERN NEVADA FRIDAY NIGHT AND
EARLY SATURDAY, USING 00Z MEX/MRA AS GUIDANCE, AND SWITCHED TO A
STRATIFORM DEPICTION OF THE PRECIPITATION. IT APPEARS THE STRONGEST
FORCING WILL COINCIDE WITH THE COLDEST AIR AND COLDEST TIME OF DAY,
INCREASING CONFIDENCE THAT SNOW ACCUMULATIONS WILL OCCUR, ESPECIALLY
ON PASSES/SUMMITS AND ELEVATED/VEGETATED SURFACES. THE SNOW IS
EXPECTED SATURDAY MORNING, WITH NO SCHOOL AND LIMITED COMMUTING, SO
THIS SHOULD WORK AGAINST ANY SIGNIFICANT IMPACTS. A WINTER WEATHER
ADVISORY MAY BE REQUIRED. NOT OUT OF THE QUESTION SOME VALLEYS IN
AND NEAR WHITE PINE COUNTY MAY TALLY UPWARDS OF 6 INCHES, AND A
WINTER STORM WATCH MAY BE CONSIDERED BY FUTURE SHIFTS.

SYSTEM IS QUITE PROGRESSIVE, MOVING TO THE GRAND CANYON SATURDAY
AFTERNOON. SNOW SHOWERS WILL RAPIDLY TAPER OFF SATURDAY AFTERNOON.
UNSEASONABLY COLD OF COURSE SATURDAY AFTERNOON, STUCK IN THE 40S,
WITH A FEW LOWER 50S ACROSS THE WESTERN/SOUTHERN ZONES.

OVERRUNNING RAIN/SNOW SHOWERS EXPECTED ACROSS NORTHERN NEVADA
SUNDAY, AS HIGH PRESSURE BEGINS TO BUILD ACROSS THE EASTERN PACIFIC.
AMOUNTS WILL BE LIGHT, CONFINED TO AREAS ALONG AND NORTH OF I-80.
TEMPERATURES RECOVER A BIT INTO THE 50S, HELD BACK BY THICK CLOUDS.

MONDAY AND TUESDAY...HIGH PRESSURE BUILDS INTO NEVADA STRONGLY, WITH
DRY WEATHER AND A RAPID WARMING TREND. BT

&&

.AVIATION...MUCH IMPROVED FLYING WEATHER FOR WEDNESDAY. DRY WEATHER
RETURNS TO ALL TERMINALS, WITH MUCH LESS WIND COMPARED TO TUESDAY.
