NATIONAL WEATHER SERVICE ELKO NV
905 AM PST MON JAN 23 2012

.SYNOPSIS...SNOW WILL CONTINUE THROUGH LATE TODAY CAUSING

PREVAIL FOR THE REMAINDER OF THE WEEK.

&&

.UPDATE...DECIDED TO UPGRADE THE WINTER WEATHER ADVISORY FOR NE
NEVADA TO A WINTER STORM WARNING THROUGH 7 PM...ABOVE 5500 FEET.
THIS WARNING INCLUDES ELKO COUNTY...AND NORTHERN LANDER AND EUREKA
COUNTIES /AGAIN ABOVE 5500 FEET/. ADDITIONAL BANDS OF SNOW WILL
CONTINUE THROUGH 7 PM. SNOW WILL BE MODERATE TO HEAVY AT
TIMES...RESULTING IN VERY LIMITED VISIBILITY AT TIMES AND SEVERAL
INCHES OF ADDITIONAL ACCUMULATION. WINDS WILL BE LIGHT SO NO
BLOWING AND DRIFTING IS EXPECTED. ROADWAYS WILL BE PARTICULARLY
HAZARDOUS IN OPEN RURAL AREAS...AND AREAS WHERE ROADS ARE NOT
TREATED OUTSIDE OF CITIES. 12Z NAM FORECASTS A STRONG MESOSCALE
BAND OF HEAVY SNOW ALONG THE INTERSTATE 80 CORRIDOR THROUGH 4
PM...FROM NEAR WINNEMUCCA TO EASTERN ELKO COUNTY. GIVEN THE
EXPECTED IMPACTS FOR TRAVELERS ALONG INTERSTATE 80...ESPECIALLY ON
THE SUMMITS/PASSES ABOVE 5500 FEET...WE FELT AN UPGRADE TO A
WARNING WAS WARRANTED. SOME VALLEYS WILL REACH STORM TOTALS OF
OVER 6 INCHES.

COLD FRONT EXPECTED TO PASS THROUGH NORTHERN NEVADA BY 4 PM.
EXPECT ENHANCED SNOWFALL RATES AT TIME OF COLD FROPA...BUT AGAIN
WINDS WILL REMAIN LESS THAN 10 MPH MOST OF THE DAY. UPSLOPE SNOW
EXPECTED TO CONTINUE ON NW FACING SLOPES THROUGH 10 PM...SO
CONTINUED THE WINTER STORM WARNING FOR THE RUBY MOUNTAINS THROUGH
THE EVENING. TURNER

AVIATION UPDATE...KWMC AND KEKO EXPECTED TO REMAIN NEAR/BELOW
CATEGORY A /LANDING MINIMUM/ THRESHOLDS THROUGH MUCH OF THE DAY.
IFR IS LIKELY...WITH OCCASIONAL LIFR/VLIFR. WINDS WILL BE LIGHT
WITH NO BLSN EXPECTED...HOWEVER RUNWAY PLOWING OPERATIONS WILL
REMAIN NECESSARY PARTICULARLY AT KEKO. -SN WILL ALSO AFFECT KTPH
AND KELY THROUGH 00Z...BUT VERY LOW CEILINGS/VISIBILITY ARE NOT
EXPECTED TO BE AS PERSISTENT ACROSS CENTRAL NEVADA. CONDITIONS ARE
EXPECTED TO RAPIDLY IMPROVE TO VFR AT ALL TAF SITES BY 06Z. TURNER

&&

.PREV DISCUSSION... /ISSUED AT 232 AM /

SYNOPSIS...A FAST MOVING LOW PRESSURE SYSTEM WILL PUSH ACROSS THE
REGION TODAY. THIS STORM WILL BE COLD ENOUGH TO PRODUCE ACCUMULATING
SNOWS OVER MUCH OF NORTHERN NEVADA. SLICK ROAD CONDITIONS ARE
ANTICIPATED. ANOTHER RIDGE OF HIGH PRESSURE WILL RETURN TO THE
SILVER STATE FOR THE REMAINDER OF THE WEEK RESULTING IN ABOVE
NORMAL TEMPERATURES AND DRY WEATHER.

SHORT TERM...TODAY THROUGH WEDNESDAY. A VERY PROGRESSIVE PATTERN
WILL BE ON DECK FOR THIS FORECAST PERIOD. ALREADY AT 700
MB...TEMPERATURES RANGE FROM -5C TO -9C...SUFFICE TO SAY THAT COLD
AIR IS IN PLACE...WITH THE TROP FOLD EXPECTED TO SWEEP ACROSS THE
LKN CWA LATER TODAY. JET STREAKS WILL CONTINUE TO PUSH EAST FROM
THE PACIFIC INTO NEVADA. FORMIDABLE CONVERGENCE AT 700 MB
CONCURRENT WITH THE FRONTAL PASSAGE ACROSS THE SILVER STATE WILL
RESULT IN ANOTHER ROUND OF WINTRY WEATHER FOR PORTIONS OF THE LKN
CWA TODAY. UPSLOPE ENHANCEMENT WILL COME INTO PLAY FOR THE SANTA
ROSA RANGE...INDEPENDENCE MTS...RUBIES AND JARBIDGE WILDERNESS
AREA. PWS WITH THIS SYSTEM WILL RANGE BETWEEN .30 TO .40 OF AN
INCH AND SNOW LEVELS WILL HOVER BETWEEN 4000 AND 5000 FEET.

PROGGED SKEW-T DATA SUGGESTS THAT THE VERTICAL COLUMN OVER THE
CITY OF ELKO FROM THE SURFACE TO ROUGHLY 650 MB WILL BE SATURATED
OR NEAR SATURATED FROM 18Z TO 21Z MONDAY...WHICH JUSTIFIES
EXPANDING THE AREAL COVERAGE OF THE WINTER WEATHER ADVISORY. THIS
WILL BE A FAST MOVING SYSTEM...AND SNOW ACCUMULATIONS ARE EXPECTED
IN THE VALLEYS. INTERESTINGLY THE ENSEMBLE MEMBERS OF THE GFS AND
EC DEPICT A WIDE SPREAD ON THE TRACK OF THE SURFACE LOW...BUT
THERE APPEARS TO BE A TIGHT CLUSTERING JUST SOUTH OF THE LKN CWA
FOR THE DURATION OF THE EVENT.

TUESDAY...THE RIDGE WILL BUILD BACK INTO THE REGION... ALONG WITH
IT...EXPECTING POSITIVE HEIGHT ANOMALIES AT 500 MB. BY 00Z
WEDNESDAY...THE EC HAS THE 570 DAM NORTH OF THE CITY OF ELKO AND
NEAR ELY...AND BY 6Z...THE 576 DAM WILL NEAR BATTLE MOUNTAIN.
EXPECTING ABOVE NORMAL AFTERNOON TEMPERATURES. THE ONLY POSSIBLE
FLY IN THE OINTMENT WILL BE IF THE SNOWPACK IN THE VALLEYS DOES
NOT MELT QUICKLY ENOUGH.

LONG TERM...WEDNESDAY NIGHT THROUGH NEXT SUNDAY. THE MODELS ARE
HAVING DIFFICULTY AGREEING THIS MORNING. THEY ARE ONLY IN GOOD
AGREEMENT THROUGH THURSDAY. MILD RIDGING IS EXPECTED WEDNESDAY NIGHT
THROUGH THURSDAY WITH PRECIPITATION BREAKING OUT NEAR THE OR/ID
BORDERS. ON THURSDAY NIGHT SOME AGREEMENT HOLDS WITH THE ECMWF BEING
THE OUTLIER SHOWING A SHALLOW SHORTWAVE MOVING THROUGH THE RIDGE
CREST. DISAGREEMENT BECOMES RAMPANT BY FRIDAY. DID NOT CHANGE MUCH
THIS SHIFT DUE TO THE INCONSISTENCIES WITH THE PATTERN. MOST POPS
ARE IN THE NORTH EACH PERIOD THROUGH FRIDAY.

AVIATION...WITH SNOWFALL EXPECTED MUCH OF THE DAY...IFR VIS AND MVFR
CIGS CAN BE EXPECTED AT KWMC AND KEKO THROUGHOUT THE DAY AND INTO
THE EVENING. KELY MAY BEGIN EXPERIENCING MVFR CONDITIONS IN THE
AFTERNOON. KTPH SHOULD PRIMARILY STAY IN THE VFR CATEGORY AS MOST
OF THE PRECIPITATION WILL BE TO THE NORTH.
