AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
852 PM PST WED DEC 17 2008

.UPDATE...

PATCHY FOG IS DEVELOPING AROUND THE RGN AS SKIES REMAIN MOSTLY
CLEAR AND TEMPS DROP. WILL ADD SOME MENTION OF FOG TO FAVORED
AREAS IN THE TAHOE BASIN...SIERRA VALLEY AND NW OF RENO. OTHERWISE
NO CHANGES TO GOING FORECAST. NEW MODEL DATA STILL SUPPORTS
DEVELOPMENT OF PCPN BY LATE THURSDAY AFTN...BUT QPF AMOUNTS NOT
QUITE AS HIGH AS PREVIOUS RUNS. MLF

&&

.PREVIOUS DISCUSSION... /ISSUED 237 PM PST WED DEC 17 2008/

..PERIODS OF SNOW THURSDAY NIGHT INTO FRIDAY...
..VERY COLD TEMPERATURES FRIDAY NIGHT AND SATURDAY...
..ACTIVE PATTERN TO CONTINUE NEXT WEEK...

SHORT TERM...

A CHALLENGING FORECAST REGARDING THURS NGT AND FRI SYSTEM. STRONG
ARCTIC COLD FRONT EXPECTED TO ROLL INTO THE AREA DURING THAT PERIOD.
ASSOC QG FORCING FOR ASCENT AND FRONTOGENESIS IS STRONG AND THERE IS
MODEST MOISTURE-STABILITY FLUX ON GFS 290K SURFACE, WHICH COMBINED
WITH STRONG OROGRAPHICS, SHOULD PRODUCE PERIODS OF SNOW.

THERE ARE UNCERTAINTIES IN QPF AMOUNTS ASSOC WITH FRONTAL PASSAGE.
SREF PLUME DIAGRAMS SHOW TWO CLUSTERS OF SOLUTIONS, ONE PRODUCING
0.8 STORM TOTAL QPF ON SIERRA CREST, WHILE OTHER SET PRODUCES 1.5.
ECMWF/GFS ARE ALSO LACKING CONSISTENCY IN QPFS. WITH THIS IN MIND,
WILL CONTINUE THE WINTER STORM WATCH FOR TAHOE/LASSEN ZONES (RATHER
THAN UPGRADE TO WARNING NOW), BUT WILL REFINE TIMING AND ADD
SURPRISE VALLEY/NRN WASHOE COUNTY TO WATCH. SPILLOVER POTENTIAL EAST
OF THE WARNERS AND SIERRA LOOKS GOOD ASSOC WITH FGEN ALOFT.

WILL BE ISSUING WINTER WX ADVISORIES FOR RENO/CARSON CITY INTO
FALLON/LOVELOCK AREAS FOR THURS NGT INTO FRI. SNOW AMOUNTS WILL
LIKELY BE ON THE LOW END OF ADVISORY LEVELS BUT CONSIDERING THAT IT
WOULD IMPACT THE FRI MORNING COMMUTE, DECIDED TO ISSUE AN ADVISORY
EARLY TO GIVE PEOPLE TIME TO CONSIDER TRAVEL OPTIONS FOR FRI
MORNING. ONE KEY TO THIS EVENT IS THAT WHILE STATEMENTS MAY BE 12-18
HOURS LONG, THE HEAVIEST SNOWS WILL LIKELY FALL QUICKLY WITHIN A 2-4
HOUR PERIOD. NOT AS MUCH SNOW IN MONO/MINERAL COUNTIES WITH FORCING
RACING EWD BY TIME SYSTEM DROPS THAT FAR SOUTH. COLD TEMPS WILL
YIELD RELATIVELY HIGH SNOW RATIOS. BASED ON CURRENT DATA, THE MOST
LIKELY SNOWFALL PROJECTIONS ARE: A FEW INCHES IN WRN NV, 3-6 IN
SURPRISE VALLEY INTO WESTERN LASSEN COUNTY, CLOSE TO A FOOT IN
TRK/TVL, WITH A COUPLE FEET OF SNOW ABOVE 7500FT. 2-4 POSSIBLE IN
MONO CO ALONG 395.

THERE IS INCREASING CONCERN FOR STRONG WINDS LATE THURS INTO FRIDAY.
MODELS SHOWING A DECENT TEMP/PRES GRADIENT ASSOC WITH FRONT + STRONG
700MB FLOW WILL RESULT IN CLOSE TO ADVISORY WIND GUSTS. ANTECEDENT
STABLE LOW LEVELS WILL INHIBIT FULL MOMENTUM TRANSFER HOWEVER. WILL
NOT ISSUE AN WIND-SPECIFIC HEADLINES ATTM, BUT WILL ADDRESS
WIND/VSBY CONCERNS IN THE WINTER STORM WATCHES. CERTAINLY LAKE WIND
ADVISORY CONDS ON TAHOE WILL EXIST PYRAMID TO A LESSER EXTENT.

TEMPERATURES WILL PLUMMET AFTER FROPA WITH NAEFS SHOWING NEG 2-3 STD
DEV TEMPERATURE ANOMALIES IN 850-700MB LAYERS ON SATURDAY. LOWS SAT
MORNING, ASSUMING SUFFICIENT CLEARING AND ADDITIONAL SNOW COVER,
WILL LIKELY BE NEAR ZERO IN WRN NV VALLEYS WITH HIGHS ONLY IN THE
LOWER 20S. WELCOME TO WINTER

CS

LONG TERM...SUNDAY THROUGH WEDNESDAY...

THE ACTIVE WEATHER PATTERN WILL CONTINUE THROUGH THE EXTENDED PERIOD
WITH STORM SYSTEMS DROPPING SOUTH AND AFFECTING THE AREA EVERY
COUPLE OF DAYS. THE NEXT LOW WILL DROP SOUTHEAST OVER THE PAC NW ON
SUNDAY AND PUSH A COLD FRONT THROUGH THE AREA SUNDAY NIGHT AND
MONDAY. OPERATIONAL MODELS AND ENSEMBLES ARE IN BETTER AGREEMENT
WITH TIMING OF THIS SYSTEM...BUT STILL VARY SOMEWHAT ON QPF AMOUNTS.
THIS BRINGS HIGHER CONFIDENCE TO THE OCCURRENCE OF PRECIPITATION
ESPECIALLY IN THE SIERRA SUNDAY NIGHT AND MONDAY. THEREFORE POPS
WERE INCREASED FURTHER DURING THESE PERIOD.

SNOW SHOWERS WILL LIKELY MOVE INTO NRN PORTIONS OF THE AREA AS EARLY
AS SUNDAY MORNING IN WARM ADVECTION AHEAD OF THE FRONT...HOWEVER
INTENSITY SHOULD BE FAIRLY LIGHT UNTIL THE FRONT NEARS. SNOWFALL
WILL INCREASE IN COVERAGE AND INTENSITY SUNDAY NIGHT AND MONDAY NEAR
THE FRONT WITH QPF AMOUNTS GENERALLY ABOVE AN INCH ALONG THE CREST
AND 0.2-0.3 ACROSS WRN NV. THIS WOULD TRANSLATE TO SNOW AMOUNTS
ABOVE A FOOT IN THE HIGH SIERRA...AND AT LEAST A FEW INCHES DOWN TO
WRN NV VALLEY FLOORS. ONCE THE FRONT MOVES THROUGH STEADY SNOW WILL
TAPER TO SHOWERS THROUGH THE EVENING. TEMPERATURES SHOULD INCREASE
INTO THE 30S SUNDAY AND MONDAY IN MANY VALLEY AREAS AS STRONGER
WINDS AHEAD OF THE FRONT SHOULD SCOUR OUT INVERSIONS. HOWEVER
TEMPERATURES WILL STILL REMAIN WELL BELOW NORMAL.

WEAK RIDGING MOVES OVER THE AREA BRIEFLY ON TUESDAY WITH A SHORT
BREAK IN THE WEATHER. THE NEXT SYSTEM IS EXPECTED TO APPROACH THE
AREA BY CHRISTMAS EVE. THERE IS STILL UNCERTAINTY WITH THIS SYSTEM
AS MODELS ARE HAVING TROUBLE WITH A SOLUTION. THE POTENTIAL EXISTS
FOR A SIGNIFICANT PRECIPITATION EVENT THROUGH THE CHRISTMAS HOLIDAY
ESPECIALLY IN THE SIERRA...BUT PRECIPITATION TYPE AND AMOUNTS HAVE
YET TO BE DETERMINED. GMCGUIRE

AVIATION...

FREEZING FOG AND VLIFR STRATUS SHOULD REDEVELOP AGAIN TONIGHT AT
KTRK AND KLOL. CONDITIONS SHOULD LIFT BY 18Z AT ALL TERMINALS AS
STRONGER WIND FLOW AHEAD OF ANOTHER STORM INCREASES. THERE IS A
CHANCE SOME STRATUS MAY WORK ITS WAY INTO THE KRNO AREA IN THE
MORNING AS WINDS PICK UP...BUT MAY JUST BE A SCT LAYER. SOUTHWEST
WIND GUSTS UP TO 20-25 KTS ARE EXPECTED THURSDAY AFTERNOON...WITH
GUSTS UP TO 32 KTS AFTER 00Z.
