AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
208 PM PST TUE JAN 8 2013

.SYNOPSIS...
A STRONG COLD FRONT WILL MOVE THROUGH WEDNESDAY EVENING BREAKING
UP THE INVERSIONS OF THE PAST FEW DAYS. THE FRONT WILL ALSO BRING
GUSTY WINDS AND SOME SNOW SHOWERS INTO THURSDAY. COLD NORTH FLOW
WILL PERSIST BEHIND THE FRONT INTO THE WEEKEND WITH WELL BELOW
NORMAL TEMPERATURES.

&&

.SHORT TERM...
SHORT WAVE RIDGE OVERHEAD WITH GENERALLY CLEAR SKIES. EXPECT THESE
TO CONTINUE THROUGH THE EVENING BEFORE CLOUDS BEGIN TO ARRIVE WITH
THE NEXT SYSTEM FOR TOMORROW. MODELS ARE IN REASONABLY GOOD
AGREEMENT FOR THE SHORT TERM WITH THE STRONG COLD FRONT FOR
TOMORROW AND THE VERY COLD AIR LASTING INTO THE WEEKEND.

TEMPERATURES WILL DROP QUICKLY THIS EVENING UNDER THE CLEAR SKIES
WITH SOME FREEZING FOG AGAIN IN THE SIERRA VALLEYS. THEN CLOUDS
ARRIVE WED MORNING WITH WINDS INCREASING ALOFT. THE STRONG VALLEY
INVERSIONS WILL HOLD INTO WEDNESDAY MORNING BEFORE THEY WEAKEN AS
700MB TEMPS COOL AND WINDS ALSO INCREASE TO 50+ KTS AT THAT LEVEL.
HAVE HOISTED WIND ADVISORIES FOR THE 395 CORRIDOR SOUTH OF RENO
AND MINERAL COUNTY TOMORROW AFTERNOON/EVENING DUE TO THE STRONG
WINDS AT THAT LEVEL. SOME OF THESE SHOULD MIX DOWN AHEAD OF THE
COLD FRONT WITH PEAK GUSTS TO AROUND 50 MPH POSSIBLE. STRONGER
GUSTS LOOK UNLIKELY AS THERE IS NO DOWNSLOPE SIGNATURE IN THE
MODEL DATA AND THE SURFACE GRADIENT IS RATHER WEAK.

BEHIND THE STRONG FRONT, TEMPERATURES WILL DROP RAPIDLY WITH A
BAND OF SNOW SETTING UP. MODELS HAVE BEEN CONSISTENT WITH THE
BAND BEING THE STRONGEST FROM SUSANVILLE TO GERLACH AND POINTS
NORTH. WHILE THE QPF IS RATHER LIGHT, THE VERY COLD TEMPS BEHIND
THE FRONT WILL RESULT IN HIGH SNOW RATIOS CLOSE TO 20 TO 1. ONLY
EXPECTING UP TO 1/4 INCH OF WATER, BUT THIS COULD TRANSLATE TO AS
MUCH AS 5 INCHES OF SNOW WEST OF SUSANVILLE. LIGHTER AMOUNTS TO
THE EAST, BUT STILL LOOKS LIKE A FAIRLY WIDESPREAD EVENT THERE OF
1 TO 3 INCHES SO A WINTER WEATHER ADVISORY WILL BE ISSUED. FURTHER
SOUTH, THE BAND LOOKS TO BREAK UP A BIT AS IT HITS I-80 WITH THE
MOST CONSISTENT PARTS OF THE BAND AROUND TAHOE AND EAST OF
LOVELOCK. AMOUNTS WOULD BE LIGHTER THAN FURTHER NORTH WITH 1-3
INCHES FOR THE TAHOE BASIN AND UP TO AN INCH OR TWO FOR WESTERN
NEVADA THAT WILL BE MORE LOCALIZED.

VERY COLD AIR FOR THURSDAY WITH TEMPS REMAINING IN THE 20S TO LOW
30S FOR THE EASTERN SIERRA AND WESTERN NEVADA. THE COLD POOL ALOFT
WILL KEEP IT UNSTABLE WITH SCATTERED SNOW SHOWERS ABOUT. WHILE THE
VERY COLD TEMPS WOULD PROMOTE LAKE EFFECT WITH THE UNIDIRECTIONAL
LIGHT TO MODERATE NORTH FLOW, THE BEST INSTABILITY OCCURS DURING
THE DIURNAL MINIMUM OF L.E.S. IN THE AFTERNOON. WOULD JUST EXPECT
SHOWERS TO BE ENHANCED AT THIS POINT AS THEY MOVE OVER LAKES
PYRAMID, TAHOE AND WALKER. COLD NORTH FLOW WILL CONTINUE INTO
FRIDAY WITH MUCH BELOW NORMAL TEMPERATURES THROUGH FRIDAY. THE
ATMOSPHERE WILL GRADUALLY BECOME MORE STABLE WITH SHOWERS ENDING
FROM NORTH TO SOUTH THURSDAY NIGHT INTO FRIDAY. WALLMANN

.LONG TERM...SATURDAY THROUGH TUESDAY...
ANOTHER ROUND OF VERY MINOR CHANGES TO THE EXTENDED FORECAST.
HIGHLY AMPLIFIED RIDGING ANCHORED OFF THE PACIFIC COAST EXTENDS
THROUGH THE GULF OF ALASKA AND INTO THE ALASKAN INTERIOR.
DOWNSTREAM, BROAD TROUGHING EXTENDS ACROSS MUCH OF THE WESTERN
U.S. THIS PATTERN WILL PERSIST THROUGH THE FORECAST PERIOD.

A WEAK IMPULSE WILL MOVE DOWN THE BACKSIDE OF THE LONGWAVE RIDGE AND
INTO THE FORECAST REGION SATURDAY. MEDIUM RANGE MODELS HAVE BEEN
STRUGGLING TO RESOLVE THIS FEATURE OVER THE LAST FEW DAYS AND
CONTINUE TO LACK A CONSENSUS. THE EC AND GEM HAVE SHOWN A SLIDER
TYPE SYSTEM MOVING THROUGH SATURDAY WHILE THE GFS KEEPS THIS FEATURE
WELL EAST OF THE REGION IN EASTERN NEVADA. THE 12Z RUN OF THE EC HAS
DRIED THIS SYSTEM OUT QUITE A BIT, BUT CONTINUE TO HAVE SLIGHT
CHANCES OF PRECIPITATION ACROSS THE SIERRA AND WESTERN NEVADA.

OTHERWISE, FLOW REMAINS COLD AND OUT OF THE NORTH THROUGH MUCH OF
THE EXTENDED. RIDGES WILL SEE PERIODS ELEVATED SPEED OVER 50 MPH AS
WINDS SHIFT NORTH TO NORTHEAST SATURDAY THROUGH MONDAY NIGHT.
TEMPERATURES WILL REMAIN BELOW AVERAGE, ESPECIALLY IN VALLEYS AS
REINFORCING COLD AIR PUNCHES SOUTH BEHIND THE WEAK SLIDER SYSTEM.
WITH RIDGING BUILDING IN EARLY TO MID WEEK, LOCATIONS ALONG HIGHER
ELEVATIONS WILL WARM WHILE COLD AIR BECOMES TRAPPED IN VALLEYS BY
STRENGTHENING INVERSIONS AGAIN. BOYD

&&

.AVIATION...
MID AND HIGH CLOUDS INCREASE AND LOWER SLOWLY OVERNIGHT THEN MORE
RAPIDLY DURING THE AFTERNOON TOMORROW AHEAD OF AN APPROACHING
SYSTEM. WITHOUT DENSE CLOUD COVER OVER MUCH OF THE NIGHT, FREEZING
FOG WILL ONCE AGAIN BE AN ISSUE IN THE SIERRA ESPECIALLY AT KTRK.
EXPECT HAZY CONDITIONS TO CONTINUE FOR WESTERN NEVADA VALLEYS AS
THEY REMAIN UNMIXED THROUGH ABOUT 18Z TOMORROW. AFTER 18Z, SOUTH
WINDS INCREASE AND BEGIN TO SCOUR VALLEYS OF AIR POLLUTION
IMPROVING VISIBILITIES. WINDS CONTINUE TO INCREASE FROM THE SOUTH
GUSTING TO 45 MPH CREATING TURBULENT CONDITIONS UP TO RIDGE LEVEL
AND WILL RESULT IN DANGEROUS FLYING CONDITIONS AT KCXP DUE TO A
STRONG CROSSWIND COMPONENT. GUST SPREAD AT KRNO MAY RESULT IN
ABRUPT AIRSPEED GAINS/LOSSES.

SNOW DEVELOPS TOMORROW EVENING FOR SIERRA LOCATIONS WITH RAIN AND
SNOW IN WESTERN NEVADA WITH SOME MVFR/IFR RESTRICTIONS POSSIBLE.
CONDITIONS IMPROVE THURSDAY TO VFR BEHIND THE FRONT AS HIGH PRESSURE
BUILDS BACK OVER THE REGION. ANOTHER SYSTEM MOVES IN OVER THE
WEEKEND. BOYD
