AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
313 AM PST THU NOV 19 2009

.SYNOPSIS...A RIDGE OF HIGH PRESSURE WILL BRING TRANQUIL WEATHER
WITH SOME SUNSHINE TO THE SILVER STATE TODAY. AN APPROACHING STORM
SYSTEM WILL RESULT IN INCREASING CLOUDS AND GUSTY SOUTH WINDS
TOMORROW. RAIN WILL CHANGE TO SNOW IN MOST AREAS TOMORROW NIGHT
INTO SATURDAY MORNING WITH MINOR SNOW ACCUMULATIONS POSSIBLE.
ANOTHER WEAK SYSTEM MAY BRING MORE PRECIPITATION SUNDAY. &&

.SHORT TERM...TODAY THROUGH SATURDAY. ALOFT...UPPER-LEVEL
SHORTWAVE RIDGE WILL DOMINATE THE WEATHER TODAY. WHILE
TEMPERATURES ALOFT WILL START TO WARM...SUBSIDENCE UNDER THE RIDGE
WILL LIMIT MIXING SO THAT MOST AREAS WILL BE ABOUT AS WARM...OR
PERHAPS EVEN A FEW DEGREES COOLER...THAN THEY WERE YESTERDAY. SOME
MID AND HIGH CLOUDS WILL FLOAT OVERHEAD...PARTICULARLY IN
NORTHWESTERN ZONES SUCH AS HUMBOLDT COUNTY...BUT OTHERWISE IT
SHOULD BE A TRANQUIL DAY.

SKIES WILL BE CLEAR TO PARTLY CLOUDY TONIGHT WITH ANY CLOUDS BEING
HIGH AND NOT SUFFICIENT TO LIMIT RADIATIONAL COOLING. THE BIGGER
INFLUENCE ON TONIGHTS LOWS WILL BE WARM AIR AND STRENGTHENING
WINDS ALOFT WHICH MAY HELP WEAKEN THE INVERSION.
NEVERTHELESS...MOST AREAS SHOULD DIP WELL INTO THE 20S WITH SOME
AREAS REACHING THE HIGH TEENS.

CLOUDS AND WINDS WILL BE ON THE INCREASE FRIDAY AS THE NEXT STORM
SYSTEM MOVES ONSHORE FROM THE PACIFIC. WINDS ALOFT WILL INCREASE
RAPIDLY...AND WITH BETTER MIXING AS HEIGHTS LOWER...EXPECT SOME
STRONGER GUSTS TO MIX DOWN TO THE SURFACE. TOYED WITH THE IDEA OF
ISSUING A WIND ADVISORY FOR CENTRAL NEVADA WITH THIS PACKAGE...BUT
DECIDED TO GIVE ONE MORE SHIFT A CHANCE TO EVALUATE THINGS.
SUSPECT THE LOWER VALLEYS OF HUMBOLDT COUNTY COMBINED WITH GREATER
CLOUD COVER REDUCING LOW LEVEL MIXING WILL MAKE IT DIFFICULT FOR
WIND ADVISORY CRITERIA TO BE REACHED THERE...THOUGH THERE MAY BE
SOME BRIEF GUSTS ABOVE CRITERIA AS SHOWERS START TO MOVE IN LATE
IN THE DAY.

THE COLD FRONT WITH THE SYSTEM WILL MOVE ACROSS THE CWA FRIDAY
NIGHT...RAPIDLY DROPPING SNOW LEVELS TO THE VALLEY FLOORS BY DAWN
SATURDAY. HOWEVER...THE CORE OF DYNAMICS ALOFT LOOKS TO PASS NORTH
OF THE CWA...SO QPF WILL BE LIMITED. RIGHT NOW...EXPECT AN INCH OR
SO OF SNOW IN THE VALLEYS... POSSIBLY UP TO TWO INCHES...ACROSS
THE NORTH...WITH LESS IN THE SOUTH. MOUNTAINS MAY RECEIVE UP TO 5
INCHES IN THE NORTH...AGAIN LESS IN THE SOUTH.

PRECIPITATION MOVES AWAY SATURDAY AS A VERY FLAT SHORTWAVE RIDGE
MOVES OVERHEAD BEHIND THE DEPARTING TROUGH. WITH VERY COLD AIR
ALOFT...EXPECT TEMPERATURES TO STRUGGLE TO REACH 40 IN MANY
VALLEYS. RCM

.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. NEAR-ZONAL FLOW
ALOFT OVER THE REGION DURING THE LATTER HALF OF THE
WEEKEND...WITH AN EMBEDDED SYSTEM CLIPPING NORTHERN NEVADA. MOST
OF THE PRECIP WITH THIS SYSTEM WILL REMAIN IN NORTHERN
NEVADA...HOWEVER COULD SEE SOME LIGHT SHOWERS ON SUNDAY EXTENDING
INTO SOUTHERN LANDER/EUREKA COUNTIES OR NORTHERN WHITE PINE
COUNTY. GFS AND ECMWF MODELS SHOWING UP TO A QUARTER INCH OF
LIQUID EQUIVALENT PRECIP OVER THE MOUNTAINS OF NORTHERN
NEVADA...WITH UP TO A TENTH OF AN INCH IN VALLEY AREAS. WITH H7
TEMPS OVER NORTHERN NEVADA SUNDAY AFTERNOON AROUND -4C...EXPECTING
RAIN OR RAIN AND SNOW MIXED IN VALLEY AREAS WITH SNOW ABOVE 5500
TO 6000 FEET.

MODEL SOLUTIONS BEGIN TO DIVERGE SUNDAY NIGHT INTO EARLY NEXT
WEEK...MAINLY WITH THE HANDLING OF SUNDAYS EXITING SYSTEM INTO
UTAH. IN GENERAL...SHOULD HAVE WEAK RIDGING OVER THE AREA MONDAY
THROUGH THURSDAY WITH DRY CONDITIONS ALONG WITH WARMER THAN NORMAL
HIGH TEMPERATURES. &&

.AVIATION...A FLAT RIDGE OVER THE REGION WILL LEAD TO VFR
CONDITIONS THROUGH FRIDAY MORNING. EXPECT TO SEE SOME HIGH TO
MID-LEVEL CLOUDS RIDING OVER THE TOP OF THE RIDGE...MAINLY INTO
NORTHERN NEVADA. WINDS TODAY WILL BE LIGHT AND VARIABLE IN MOST
AREAS. &&

.LKN WATCHES/WARNINGS/ADVISORIES...NONE. &&
