AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
330 AM PST SUN DEC 25 2005

.SHORT TERM...
LOW CLOUDS AND FOG HAS REFORMED NEAR PYRAMID LAKE AND IN THE SINKS
OF ZONE 4.  REPORTED VISIBILITIES ARE 1/4 TO 1/2 MILE.  WINDS WILL
NOT REACH THE FOGGY AREAS UNTIL THIS AFTERNOON...SO WILL ISSUE
ANOTHER DENSE FOG ADVISORY FOR THIS MORNING.

SHORT WAVE OFF THE COAST OF OREGON HAS KICKED THE RIDGE OVER
UTAH...LEAVING THE WEST COAST WIDE OPEN TO SERIES OF IMPRESSIVE
SYSTEMS IN THE PACIFIC.  STRONG JET CURRENTLY EXTENDS NEARLY ACROSS
THE ENTIRE PACIFIC ALONG AND JUST SOUTH OF 40N.  WINDS ALREADY
INCREASING IN THE SIERRA WITH WIND GUSTS NEAR 80 MPH OVER THE CREST
AND NEAR 35 MPH AT THE LOWER ELEVATIONS.  WINDS HAVE MIXED OUT THE
INVERSION WITH TEMPERATURES JUMPING 20 DEGREES OR SO IN LESS THAN 3
HOURS.  SOUTH LAKE TAHOE WENT FROM 1/4SM FG AND 30 DEG TO 10SM AND
49 DEG...EARLIER TONIGHT. WILL NEED TO INCREASE TEMPERATURES AS THE
INVERSION GETS MIXED OUT.  COULD HIGHS NEAR 60 IN A FEW LOCATIONS.
WINDS REMAIN LIGHT IN THE WESTERN NEVADA VALLEYS BUT ONCE THE WINDS
INCREASE LATER TODAY WILL SEE A RAPID JUMP IN TEMPERATURES.
EXPECTING VALLEY HIGHS BETWEEN 55 AND 60.

FIRST PROBLEM OF THE DAY IS WILL THE LOWER ELEVATION WINDS INCREASE
TO ADVISORY LEVELS THIS AFTERNOON. MODELS SHOW STRONGER WINDS WILL
MOVE INTO THE AREA AFTER 00Z...SO GUSTS SHOULD REMAIN AT OR JUST
BELOW ADVISORY CRITERIA UNTIL TONIGHT.  DAY SHIFT WILL NEED TO
REEVALUATE FOR TONIGHT...BUT LOOKS LIKE A WIND ADVISORY WILL BE
NECESSARY FOR THE EAST SLOPES OF THE SIERRA.

NEXT PROBLEM OF THE DAY IS THE TROUGH PROGGED TO PASS OVER THE
SIERRA AND WESTERN NEVADA BETWEEN 06Z-18Z MONDAY.  THERE IS STILL
SOME QUESTION AS TO WHERE THE HEAVIEST PRECIPITATION WILL FALL.
YESTERDAY THE GFS FAVORED AREAS FROM TAHOE SOUTH...BUT TODAY THE GFS
FAVORS AREAS FROM TAHOE NORTH.  THE NAM IS THE OPPOSITE AND SHOWS
THE SPLIT IN THE TROUGH THE GFS SHOWED YESTERDAY WITH THE MAIN VORT
MAX TRACKING OVER THE CENTRAL SIERRA. EITHER WAY IT SEEMS THAT TAHOE
WILL GET WARNING LEVEL ACCUMULATIONS...BUT THE UNCERTAINLY LIES TO
THE NORTH AND SOUTH OF TAHOE DEPENDING ON WHICH MODEL YOU BELIEVE
THE MOST.  TEND TO FAVOR THE GFS SINCE IT IS MORE LIKELY TO HAVE THE
BETTER HANDLE ON THE LARGE SCALE SYSTEMS THAN THE NAM.  RIGHT NOW
THIS SYSTEM ISNT EVEN IN THE NAM MODEL DOMAIN.  WILL LEAVE THE WATCH
AS IS FOR NOW AND GIVE THE DAY SHIFT ANOTHER MODEL RUN OR TWO TO SEE
IF THE DIFFERING GFS/NAM SOLUTIONS CONVERGE.

BEYOND MONDAY A RIDGE RAPIDLY BUILDS OVER NEVADA IN THE PROGRESSIVE
WESTERLY FLOW. THIS RIDGE WILL BEING TO BREAK DOWN TUESDAY EVENING
AS A MUCH MORE IMPRESSIVE SYSTEM NEARS THE NORTHERN CALIFORNIA
COAST. BRONG

.LONG TERM...WEDNESDAY THROUGH SATURDAY...
AN UNSEASONABLY MILD AND WET PATTERN TO CONTINUE AS COLD HEIGHT
ANOMALY PERSISTS OVER MUCH OF THE NORTH PACIFIC EXTENDING INTO THE
PACIFIC NORTHWEST. THIS PATTERN IS ALLOWING FOR A PERSISTENT AND
VERY INTENSE MID LATITUDE JET STREAM TO PUSH MILD PACIFIC AIR INTO
THE REGION AND TO TAP A VERY MOIST TROPICAL AIRMASS FROM THE LOWER
LATITUDES OF THE WESTERN TROPICAL PACIFIC. SATELLITE IMAGERY
CONTINUED TO SHOW PRECIPITABLE WATER PLUME NEAR TWO INCHES EXTENDING
FROM EAST OF INDONESIA ACROSS THE CENTRAL PACIFIC TO NORTHEAST OF
HAWAII. DYNAMICS ARE BECOMING INCREASINGLY INTENSE AS THE CORE OF
THE STRONGER PACIFIC JET EXTENDS FURTHER EASTWARD THAN IN THE PAST
COUPLE OF WEEKS. THE GFS/ECMWF/CANADIAN ARE IN VERY GOOD AGREEMENT
WITH THE FIRST WAVE DUE WEDNESDAY/WEDNESDAY NIGHT AND THE GFS IN
PARTICULAR HAS SHOWN THIS FEATURE FOR MANY RUNS. CONFIDENCE IS THUS
VERY HIGH AND POPS WERE RAISED TO CATEGORICAL/LIKELY OVER MANY
AREAS. THIS STORM WILL HAVE TO BE MONITORED CLOSELY AS IT HAS
CHARACTERISTICS OF A VERY WET TROPICAL ENVIRONMENT MUCH LIKE THE
LAST FEW SYSTEMS. IN ADDITION...MODEL DATA POINTS TO VERY STRONG
FRONTAL ZONE AND ASSOCIATED DYNAMICS. THIS WOULD GREATLY ENHANCE
PRECIPITATION WHICH WOULD MEAN VERY HEAVY SNOW FOR THE SIERRA AND
POTENTIAL HEAVY RAIN FOR THE VALLEYS. VERY TIGHT SURFACE GRADIENT
ALONG WITH SOUNDING PROFILES ALSO SUGGEST THE POTENTIAL FOR STRONG
AND EVEN DAMAGING WINDS AHEAD OF THE FRONT/PRECIPITATION WEDNESDAY.
THE REGION WILL CONTINUE IN A FAST PACIFIC FLOW WITH ANOTHER WAVE
SOMETIME LATE WEEK/OVER THE WEEKEND. DETAILS ARE SKETCHY AND TIMING
WILL BE QUITE DIFFICULT. THEREFORE POPS WERE LEFT TO CHANCE OR
SLIGHT CHANCE THROUGH THE END OF THE FORECAST PERIOD. TEMPERATURES
WILL SEE SOME FLUCTUATION WITH READINGS GENERALLY ABOVE NORMAL. IN
PARTICULAR RAISED MAXIMA WEDNESDAY AS STRONG WINDS WILL MIX ALL
VALLEY LOCATIONS AND ALLOW SOME PLACES INCLUDING LOVELOCK TO SEE
THEIR WARMEST TEMPERATURES IN AWHILE. HOHMANN
&&

.AVIATION...
FOG LESS AN ISSUE TONIGHT UNDER WEAKENING INVERSION AND INCREASING
WINDS AT RIDGE LEVEL/BETTER MIXING...ESPECIALLY AT KTRK/KTVL TAF
SITES WHERE WINDS HAVE BEEN QUITE GUSTY OVERNIGHT. VALLEY INVERSION
WILL CONTINUE TO TRAP LOW CLOUDS AND FOG/FREEZING FOG IN AREAS OF
THE BASIN AND RANGE INCLUDING KLOL/KNFL. FOG AND LOW CLOUDS SHOULD
LIFT BY 17Z AS INVERSIONS CONTINUE TO WEAKEN AND MID/HIGH CLOUD
LAYERS THICKEN. GENERALLY VFR AFTER 17Z UNTIL PRECIPITATION PICKS UP
LATE TONIGHT/EARLY MONDAY MORNING. HOHMANN
