AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
309 AM PST WED FEB 10 2016

.SYNOPSIS...THE RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE
SOUTHWESTERN UNITED STATES FOR THE TIME BEING...KEEPING THE
WEATHER QUIET AND DRY OVER NORTHERN NEVADA. FREEZING FOG IS A
POSSIBILITY OVER THE VALLEY LOCATIONS EACH MORNING. A WEAK
DISTURBANCE WILL MOVE OVER THE AREA THROUGH THE WEEKEND...WITH
LIMITED CHANCES FOR PRECIPITATION.

&&

.SHORT TERM...TODAY THROUGH FRIDAY. CONSIDERABLE HIGH CLOUDINESS
IS MOVING ACROSS NORTHERN NEVADA THIS MORNING. FREEZING FOG WAS
BEGINNING TO DEVELOP EARLIER IN THE NIGHT ACROSS ELKO AND SPRING
CREEK...AND THE CLOUDS MAY HAVE DISRUPTED THAT. CURRENT
TEMPERATURE AND DEWPOINT SPREADS ARE BETWEEN THREE AND FIVE
DEGREES ACROSS THE AREA...AND BELIEVE THIS IS TOO CLOSE TO
COMPLETELY REMOVE FREEZING FOG FROM THE GRIDS...SO HAVE CUT BACK
TO JUST PATCHY WORDING.

FOR TODAY AND TONIGHT...LOOK FOR MAINLY SUNNY SKIES TODAY AS HIGH
CLOUDS TRANSIT NORTHERN AND CENTRAL NEVADA. WINDS WILL REMAIN
LIGHT. AFTERNOON HIGHS ARE EXPECTED TO FOLLOW THE TREND OF THE
LAST FEW DAYS...WITH HIGHS IN THE 30S ACROSS VALLEY LOCATIONS WITH
SNOW COVER AND 50S IN THOSE AREAS WITH LIMITED OR NO SNOW COVER.
FOR TONIGHT...KEPT THE PREVIOUS FORECAST FOR FREEZING FOG WITH
OVERNIGHT LOWS DIPPING INTO THE SINGLE DIGITS AND TEENS UP TO THE
MID 20S.

ON THURSDAY AND FRIDAY...THE UPPER LEVEL RIDGE WILL GRADUALLY
BECOME MORE DEPRESSED ACROSS NORTHERN NEVADA. THIS WILL ALLOW
PERIODS OF HIGH CLOUDS TO PUSH ACROSS NORTHERN AND CENTRAL NEVADA
FROM TIME TO TIME. AFTERNOON HIGHS WILL BE SIMILAR TO WEDNESDAY
WITH READINGS IN THE 30S ACROSS THE VALLEY AREAS WITH SNOW PACK TO
THE 50S WITH LIMITED SNOW COVER. WITH THE POSSIBILITY OF MELTING
SNOW...HAVE KEPT THE POSSIBILITY OPEN FOR AREAS OF FREEZING FOG TO
DEVELOP BOTH NIGHTS. OVERNIGHT LOWS WILL BE IN THE SINGLE DIGITS
TO 20S. WINDS WILL REMAIN LIGHT BOTH DAYS.

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY. SHORT WAVE MOVING ACROSS
THE PACIFIC NORTHWEST FRIDAY NIGHT AND SATURDAY WILL FLATTEN UPPER
RIDGE. THE GFS DIGS THIS SHORT WAVE A LITTLE FURTHER SOUTH
INDICATING THE POSSIBILITY OF A FEW SHOWERS ACROSS NORTHERN NV.
HOWEVER THE CANADIAN/EURO MODEL SHOW SHORT WAVE REMAINING FURTHER
NORTH WITH ANY PRECIP NORTH OF THE OREGON/IDAHO BORDER. WITH SUCH
STRONG RIDGE CURRENTLY IN PLACE WENT WITH THE CAN/EURO SOLUTION OF
MORE RIDGING REMAINING OVER THE AREA, WITH A DRY FORECAST CONTINUING
THROUGH THE WEEKEND. WITH MORE CLOUD COVER OVER THE WEEKEND
OVERNIGHT LOW WILL MODERATE ACROSS THE SNOW COVERED VALLEYS,
ESPECIALLY ACROSS NORTHERN NV.

&&

.AVIATION...CONSIDERABLE HIGH CLOUDS MOVING ACROSS NORTHERN AND
CENTRAL NV EARLY THIS MORNING AND THIS WILL HELP INHIBIT FOG
FORMATION. ANOTHER LIMITING FACTOR IN FOG FORMATION AT KEKO IS
NORTHEAST DRAINAGE WINDS A LITTLE STRONGER THAN YESTERDAY. OTHERWISE
STRONG HIGH PRESSURE OVER THE REGION WITH VFR CONDITIONS.

&&

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