High Wind in Nevada, January 31, 2011

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE ELKO NV
318 AM PST MON JAN 31 2011

.SYNOPSIS...COLD AND BLUSTERY CONDITIONS ALONG WITH SCATTERED
MOUNTAIN SNOW SHOWERS ARE EXPECTED TODAY THROUGH TUESDAY...AS AN
ARCTIC AIRMASS MOVES INTO THE GREAT BASIN. TEMPERATURES WILL BEGIN
TO MODERATE BY WEDNESDAY AS AN AREA OF HIGH PRESSURE BUILDS INTO
THE SILVER STATE.

&&

.SHORT TERM...TODAY THROUGH WEDNESDAY. WEAK SHORTWAVE AND 700MB
MOISTURE WILL BRING MOSTLY CLOUDY SKIES...SCATTERED MOUNTAIN SNOW
SHOWERS AND VALLEY FLURRIES TODAY. NO ACCUMULATIONS ARE EXPECTED
TODAY...EXCEPT FOR A FEW INCHES IN THE MOUNTAINS OF NORTHERN
NEVADA. 700MB WINDS WILL REACH 35KTS TODAY OUT OF THE
NORTHWEST...COUPLED WITH A WEAK STABLE LAYER JUST ABOVE RIDGE TOP
OF THE RUBIES WILL LEAD TO GUSTY LEE-SIDE WINDS. HAVE ISSUED A WIND
ADVISORY VALID THROUGH 4PM TODAY FOR THE CLOVER AND RUBY VALLEY
AREAS. LOOKS TO BE GUSTY IN THE WENDOVER AND TONOPAH AREAS ALSO
TODAY...BUT WINDS SHOULD STAY JUST BELOW ADVISORY CRITERIA.

TUESDAY A DEEP 500MB TROUGH WILL DIG INTO THE INTER-MOUNTAIN
WEST...WITH AN ASSOCIATED ARCTIC FRONT MOVING THROUGH EASTERN NV.
MOUNTAIN SNOW SHOWERS WILL CONTINUE DURING THE DAY ON TUESDAY
ACROSS THE EASTERN MOUNTAIN RANGES...BUT ACCUMULATIONS WILL BE
VERY LIGHT WITH ONLY SHALLOW 700MB MOISTURE WITH THIS FEATURE. THE
BIGGEST IMPACT WILL BE THE VERY COLD TEMPS COMBINED W/ THE WINDS
CREATING A BLUSTERY DAY. WINDCHILL VALUES WILL ONLY TOP OUT IN THE
SINGLE DIGITS TO LOW TEENS...SO A VERY UNPLEASANT DAY TO BE OUT
AND ABOUT. WILL HAVE TO WATCH FOR WIND ADVISORIES
ALSO...ESPECIALLY FOR NORTHERN NYE COUNTY...WITH A 16MB PRESSURE
GRADIENT ACROSS THE SILVER STATE...DUE TO A STRONG 1050MB HIGH
OVER MONTANA AND A DEVELOPING SURFACE LOW OVER ARIZONA. 700MB
NORTHERLY WINDS WILL PEAK AROUND 40KTS ON TUESDAY...WITH STRONGEST
WINDS EXPECTED IN NORTH/SOUTH ORIENTED VALLEYS WHERE THE COLD
DENSE AIR WILL BE CHANNELED. WINDS WILL SUBSIDE ON TUESDAY
NIGHT...BUT NOT ENOUGH TO ALLOW FOR STRONG INVERSIONS TO
DEVELOP...THUS LOWS WILL BE MODERATED QUITE A BIT COMPARED TO WHAT
IT COULD BE WITH -20C 700MB TEMPS.

ARCTIC AIRMASS QUICKLY MOVES EAST ON WEDNESDAY ALLOWING TEMPS TO
MODERATE A GOOD 5 TO 10 DEGREES WITH LIGHTER WINDS ALSO EXPECTED.
IT WILL STILL BE COLD THOUGH WITH MOST LOCATIONS ONLY REACHING THE
LOW 30S...BUT IT WILL BE SUNNY.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY. NOT MUCH TO SPEAK OF
WEATHER WISE THROUGH THE LONG TERM AS THE CWA WILL REMAIN UNDER
NORTHERLY TO NORTHWESTERLY FLOW ON THE EASTERN SIDE OF THE RIDGE
WHICH WILL BE SITTING JUST OFF THE WEST COAST THROUGH THE PERIOD.
TEMPERATURES WILL MODERATE FROM THE CHILLY READINGS EXPECTED
TUESDAY AND WEDNESDAY HOWEVER. MAIN CONCERN IS FOR WEAK
DISTURBANCES SLIDING SOUTHWARD ON THE BACK SIDE OF THE
RIDGE...WHICH WILL BE MOST LIKELY OVER THE WEEKEND AS THE RIDGE
SHIFTS A BIT FURTHER OFFSHORE AND THE FLOW BECOMES FLATTER AND
MORE NORTHWESTERLY ALOFT. HARD TO TIME THESE DISTURBANCES EXACTLY
SO HAVE GENERALLY HAVE INCREASED CLOUD COVER AND SLIGHT CHANCE
POPS ACROSS THE HIGHER ELEVATIONS THROUGH THE WEEKEND. NO
SIGNIFICANT CHANGES WERE MADE TO THE PREVIOUS PACKAGE. RCM

&&

.AVIATION...OVERALL...VFR CONDITIONS ARE EXPECTED AT ALL
TERMINALS THROUGH THE NEXT 24 HOURS. BRIEF MVFR CIGS AND VIS ARE
POSSIBLE AT KEKO AND KELY WITH SCATTERED SNOW SHOWERS...THOUGH THE
LIKELIHOOD IS LOW. THESE SHOULD BE CONFINED TO THE AFTERNOON AND
EVENING HOURS TODAY AND THUS HAVE NOT INCLUDED ANY TEMPOS AS OF
YET. WINDS WILL BE AN ISSUE AT KTPH WITH GUSTS EXPECTED TO
OCCASIONALLY EXCEED 30 KNOTS BY THIS AFTERNOON. LIGHTER WINDS ARE
EXPECTED ELSEWHERE.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...
WIND ADVISORY UNTIL 4 PM PST THIS AFTERNOON FOR THE EASTERN
SLOPES OF THE RUBY MOUNTAINS/EAST HUMBOLDT RANGE IN THE
SOUTHWEST AND SOUTH CENTRAL ELKO COUNTY.
