AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE RENO NV
942 AM PST TUE NOV 24 2015

.UPDATE...
QUICK UPDATE TO SPEED UP THE TIMING OF THE RAIN/SNOW INTO THE
SIERRA FRONT. TIMING LOOKS TO BE MORE EARLY/MID AFTERNOON THAN
LATE AFTERNOON. OTHERWISE THE FORECAST IS ON TRACK AND NO OTHER
CHANGES ARE PLANNED. WINDS CONTINUE THIS MORNING WITH GUSTS UP TO
50 MPH MOST VALLEY LOCATIONS IN THE ADVISORIES WITH A FEW GUSTS TO
70 MPH IN WIND PRONE AREAS. RAIN/SNOW HAS BEGUN IN LASSEN COUNTY
AND ALONG DONNER SUMMIT THIS MORNING AS WELL. SNOW LEVELS ARE
CURRENTLY NEAR 5000 FEET. WALLMANN

&&

.SYNOPSIS...

A POTENT PACIFIC LOW WILL MOVE INTO NORTHEAST CALIFORNIA AND WESTERN
NEVADA TODAY. GUSTY WINDS ARE EXPECTED AHEAD OF A STRONG COLD FRONT
WITH SNOW BEHIND IT. SNOW WILL TAPER TO SHOWERS BY WEDNESDAY WITH
WELL BELOW NORMAL TEMPERATURES. THE LOW WILL REMAIN OVER NEVADA INTO
THE WEEKEND WITH CONTINUED VERY COLD TEMPERATURES AND A FEW SNOW
SHOWERS.

&&

.PREVIOUS DISCUSSION... /ISSUED 349 AM PST TUE NOV 24 2015/

SHORT TERM...

ANOTHER ROUND OF MINOR TO MODERATE ADJUSTMENTS AS MODELS CHANGE
SUBTLY FROM PREVIOUS RUNS. THE OVERALL TREND HAS BEEN DRIER FOR
LOWER VALLEYS AS SHADOWING INCREASES. ADDITIONALLY, THE SPEED OF
THE SYSTEM IS SHOWN TO INCREASE ONCE IT MOVES INTO THE NORTHERN
SIERRA THIS AFTERNOON. AS A RESULT, HAVE MARGINALLY LOWERED SNOW
TOTALS ACROSS LOWER VALLEYS. GENERALLY, THIS HAS KNOCKED DOWN THE
TOTALS AN BY AROUND AN INCH FOR MOST VALLEYS LOWER THAN 5000 FEET
SOUTH OF A PORTOLA TO GERLACH LINE. ADDED SOME THUNDER ALONG THE
FRONT PRIMARILY IN THE SIERRA THROUGH THIS AFTERNOON; CONVECTIVE
SNOW WILL CONTRIBUTE TO MORE WIDELY VARIABILITY IN SNOW
ACCUMULATIONS FOR SIERRA LOCATIONS.

WHILE SOME OF THE TOTAL ACCUMULATIONS CHANGED, IMPACTS HAVE
INCREASED WITH THE FASTER FRONTAL SPEED. TIMING OF THE FRONT NOW
POSES A THREAT TO TRAVELERS THIS AFTERNOON DURING RUSH HOUR
ESPECIALLY AROUND THE RENO/CARSON CITY METRO AREAS. TRAVEL WILL
BECOME DIFFICULT AS BLOWING SNOW REDUCES VISIBILITY THIS
AFTERNOON. ROADS WILL BEGIN WARM ENOUGH TO LIMIT SOME OF THE
ICIEST CONDITIONS, BUT TEMPERATURES WILL QUICKLY FALL. ROADS,
ESPECIALLY THOSE THAT ARE UNTREATED, WILL BECOME SLICK IN THE
EVENING AS SURFACE TEMPERATURES CROSS 32 DEGREES.

ADDITIONALLY, PERSISTENT WESTERLY FLOW BEHIND THE FRONT WILL
CREATE ADEQUATE CONDITIONS TO SUPPORT LAKE EFFECT SNOW OFF OF LAKE
TAHOE FROM WASHOE VALLEY THROUGH DOUGLAS COUNTY. ADDITIONAL
ACCUMULATIONS COULD RANGE FROM 5 TO 10 INCHES DEPENDING ON HOW
LONG BANDS PERSIST IN ANY GIVEN AREA. THE HIGHEST ACCUMULATIONS
WILL BE IN THE CARSON RANGE DECREASING TO HIGHWAY 395. TRAVEL
CONDITIONS WILL BE POOR OVERNIGHT INTO WEDNESDAY. THEREFORE, HAVE
ISSUED A WINTER WEATHER ADVISORY FOR THE SIERRA FRONT FROM 4 PM
THIS AFTERNOON THROUGH 4 PM WEDNESDAY. HELD OFF FOR NORTHERN LYON
COUNTY WHERE WINDS WILL BE LIGHTER AROUND PYRAMID LAKE.

STEEP LAPSE RATES AND MOISTURE REMAIN UNDER THE COLD CORE OF THE
LOW. INCREASED PRECIPITATION CHANCES OF SNOW SHOWERS FOR THE
AFTERNOON. SOME LOCATIONS COULD RECEIVE A FEW CONVECTIVE SHOWERS
WITH SOME ADDITIONAL ACCUMULATION. FORECASTER CONFIDENCE IS LOW
FOR ANY ONE LOCATION GIVEN THE CONVECTIVE NATURE OF THE SHOWERS.
OTHERWISE, CONDITIONS REMAIN UNSETTLED WITH SLIGHT CHANCES OF SNOW
SHOWERS THROUGH THURSDAY WITH THE LOW REMAINING OVER NORTHERN
NEVADA.

AS FAR AS PREVIOUSLY ISSUED WINTER STORM WARNINGS AND WIND
ADVISORIES, THESE AREAS ARE STILL ON TRACK. GUSTY WINDS WILL
PRECEDE THE FRONT WITH WIND GUSTS GENERALLY UP TO 50 MPH; UP TO 55
ALONG THE SIERRA FRONT. WIND PRONE AREAS COULD HAVE GUSTS AS HIGH
AS 70 MPH ESPECIALLY IN THE FOOT HILLS OF THE SIERRA. THESE WINDS
WILL KICK UP DUST MAINLY OVER THE BASIN AND RANGE POSING A RISK TO
TRAVELERS ALONG INTERSTATE 80. SNOW ACCUMULATIONS CONTINUE TO
RANGE UP TO A FOOT OVER 7000 FEET, AROUND 6 INCHES DOWN TO LAKE
TAHOE LEVEL. GENERALLY 6-12 INCHES WEST OF HIGHWAY 395 FOR LASSEN
COUNTY AND AROUND 4 TO 8 INCHES(OVER 30 HRS) FOR LOWER VALLEYS
FROM LASSEN TO THE SURPRISE VALLEY AND NORTHERN WASHOE COUNTY. IN
MONO COUNTY, 6 TO 12 INCHES WEST OF HIGHWAY 395 AND UP TO 6 INCHES
EAST OF HIGHWAY 395. CONFIDENCE HAS DECREASED A LITTLE WITH TOTALS
FOR MONO COUNTY SINCE THE SPEED OF THE SYSTEM HAS INCREASED; MAY
SEE SLIGHTLY LOWER TOTALS. ELSEWHERE, UP TO 2 INCHES WILL BE
POSSIBLE MAINLY ALONG THE COLD FRONT.

FINALLY...TEMPERATURES WILL BE VERY COLD, AS MUCH AS 15 DEGREES
BELOW SEASONAL AVERAGES. EXPECT HARD FREEZES TONIGHT THROUGH THE
END OF THE WEEK FOR WESTERN NEVADA AND THE SIERRA. HIGHS WILL
STRUGGLE TO REACH FREEZING FOR URBAN CENTERS WEDNESDAY AND
THURSDAY. OUTDOOR PETS WILL BE SUSCEPTIBLE AND MAY REQUIRE
ADDITIONAL CARE. TEMPERATURES WILL BE DANGEROUS IN THE BACK-COUNTY
IF PROPER ATTIRE IS NOT WORN. IT IS BEST TO KEEP BLANKETS AND
EXTRA WATER/FOOD IN YOUR VEHICLE ESPECIALLY WITH EXPECTED TRAVEL
DELAYS. BOYD

LONG TERM...FRIDAY THROUGH TUESDAY...

THE WINTER STORM SET TO MOVE THROUGH TODAY THROUGH WEDNESDAY WILL
RETROGRADE BACK OVER THE REGION FRIDAY-SATURDAY. AS A RESULT, WE
WILL MAINTAIN COLD TEMPERATURES ALONG WITH CHANCES FOR SNOW SHOWERS.
ALTHOUGH CONFIDENCE IS INCREASING THAT THE LOW WILL RETROGRADE BACK
ACROSS THE SIERRA, THE SNOW AMOUNTS WILL BE MUCH LOWER THAN ITS
FIRST GO AROUND. THE GFS DEPICTS A BETTER POTENTIAL FOR SNOWFALL
VERSUS THE ECMWF, BUT BELIEVE THE LOW TO MID LEVEL CONVERGENCE NEAR
THE LOW COUPLED WITH PRESENT INSTABILITY AND MOISTURE SHOULD ALLOW
FOR SNOW SHOWER DEVELOPMENT. HAVE INCREASED PRECIPITATION CHANCES AS
A RESULT.

TRAVEL IMPACTS ARE A POSSIBILITY FRIDAY AFTERNOON THROUGH SATURDAY
MORNING ACROSS THE SIERRA WITH SEVERAL INCHES OF ADDITIONAL SNOWFALL
POSSIBLE AND EVEN SOME ACCUMULATING SNOW POSSIBLE OVER PORTIONS OF
WESTERN NEVADA. MUCH OF THIS DEPENDS ON THE EXACT TRACK OF THE LOW
AND WILL CONTINUE MONITOR THE TRACK OF THE RETROGRADING LOW.

THE LOW CLEARS OUT SUNDAY WITH THE PATTERN ACROSS THE EASTERN
PACIFIC SHOWING NOTHING TO IMPEDE INCOMING STORMS SYSTEMS. MODEL
GUIDANCE REFLECTS THIS BY BRINING IN A WEAK SYSTEM ON MONDAY WITH A
MORE POTENT SYSTEM ON TUESDAY. DETAILS ARE LOW CONFIDENCE BUT WITH
NO BLOCKING RIDGE ACROSS THE EASTERN PACIFIC IT LOOKS FAVORABLE TO
MAINTAIN AN ACTIVE PATTERN INTO EARLY NEXT WEEK. FUENTES

AVIATION...

GUSTY WINDS ARE BEGINNING TO DEVELOP AND WILL INTENSIFY THROUGH
THE AFTERNOON HOURS. TURBULENCE AND LLWS ARE POSSIBLE THROUGH THE
MORNING AND EARLY AFTERNOON IN THE LEE OF THE SIERRA. SNOW IMPACTS
ON AVIATION WILL ALSO BEGIN IN THE SIERRA AND AREAS NORTH OF I-80
BY THIS AFTERNOON, AND SPREAD QUICKLY SOUTH OF I-80 BY THIS
EVENING. IFR/LIFR CONDS ARE LIKELY AT THE SIERRA TERMINALS FOR
SEVERAL HOURS, WITH A SHORT PERIOD OF IFR VSBY/CIGS FOR KRNO-KCXP
THIS EVENING AS BAND OF MIXED RAIN/SNOW CHANGES TO SNOW BEHIND THE
COLD FRONT.

FOR WEDNESDAY, SNOW SHOWERS WILL CONTINUE TO PRODUCE MOUNTAIN
OBSCURATION AND PERIODS OF IFR VSBY/CIGS ESPECIALLY FOR THE SIERRA
TERMINALS. RIDGE WINDS WILL DECREASE, WHILE LIGHTER WINDS ARE
EXPECTED FOR LOWER ELEVATIONS. MJD/TF
