AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
848 AM PST SUN FEB 26 2012

.UPDATE...
ADDED 3-5 DEGREES TO THE AFTERNOON HIGHS TODAY SOUTH OF I-80 AS
INCREASING SOUTH-SOUTHWEST WINDS AHEAD OF A PACIFIC LOW WILL HELP
MIXING LATER TODAY. TEMPERATURE GUIDANCE HAS A LARGE SPREAD FOR
TODAY, SO LEANED CLOSER TO THE HIGHER VALUES. MOST WESTERN NEVADA
VALLEYS SHOULD CLIMB TO NEAR 50, WITH 40S IN THE SIERRA SOUTH OF
I-80. NORTH OF I-80 EXTENSIVE CLOUD COVER WILL LIMIT WARMING, WITH
HIGHS TRAPPED IN THE MID 30S TO LOW 40S. BRONG

&&

.PREVIOUS DISCUSSION... /ISSUED 340 AM PST SUN FEB 26 2012/

SHORT TERM...
CURRENT WATER VAPOR IMAGERY DEPICTS TWO STACKED SHORTWAVE TROUGH
SYSTEMS MOVING SOUTHEAST AND SLOWLY BEGINNING TO MERGE TOGETHER OFF
THE COAST OF BRITISH COLUMBIA. THESE TWO SYSTEMS WILL COMBINE TO
FORM A COLD AND UNSTABLE TROUGH OVER NORTHERN CA/NV BY THIS EVENING.

CLOUD COVER WILL INCREASE TODAY WHILE WINDS ALOFT STRENGTHEN FROM
THE SOUTHWEST AS THE TROUGH APPROACHES. THIS SYSTEM WILL BRING VERY
COLD AIR ALOFT OVER THE REGION, WITH H700 TEMPS DROPPING TO -14C,
WHICH WILL CREATE UNSTABLE CONDITIONS CONDUCIVE FOR SNOW SHOWER
DEVELOPMENT TONIGHT INTO MONDAY. SNOW LEVELS WILL REMAIN AT VALLEY
FLOORS WITH LIGHT ACCUMULATION EXPECTED MAINLY IN THE SIERRA, WITH
UP TO 4 INCHES ABOVE 7000 FEET AND UP TO 2 INCHES AT LAKE LEVEL.
SNOW WILL BE OF THE POWDER VARIETY DUE TO COLD TEMPERATURES PROVIDING
EFFICIENT SNOW DEVELOPMENT CONDITIONS.

THE COLD AIR WITH EXTENSIVE CLOUD COVER WILL LIMIT HIGHS TO THE 30S
FOR WESTERN NEVADA AND 20S TO LOW 30S IN THE SIERRA MONDAY. ONCE THE
SYSTEM PUSHES EAST MONDAY EVENING, TUESDAY MORNING LOWS COULD DROP
INTO THE SINGLE DIGITS FOR THE SIERRA AND INTO THE TEENS TO MID 20S
FOR WESTERN NV.

TUESDAY WILL SEE A QUICK INCREASE IN DAYTIME TEMPERATURES AS A
SHORTWAVE RIDGE BUILDS IN. HOWEVER, A SECOND SHORTWAVE SYSTEM WILL
BEGIN TO IMPACT THE SIERRA AND WESTERN GREAT BASIN BY LATE TUESDAY.
SOUTHWEST WINDS WILL INCREASE AHEAD OF THE SYSTEM TUESDAY AFTERNOON
AND PERSIST OVERNIGHT. THIS SYSTEM IS MORE DYNAMIC THAN THE PREVIOUS
ONE, WITH MODELS ALL SHOWING A 115+ KT JET NOSING INTO NORTHERN
CA/NV TUESDAY NIGHT. THIS COUPLED WITH INCREASING MOISTURE FROM A
NEAR 1 INCH PW PLUME OFF THE CA COAST WILL BRING PRECIPITATION TO
NORTHERN CA AND FAR NORTHWESTERN NV BY TUESDAY EVENING. PRECIPITATION
WILL CONTINUE OVERNIGHT AS THE ASSOCIATED COLD FRONT ROLLS THROUGH.

AHEAD OF THE COLD FRONT, MID LEVEL SOUTHWEST FLOW WILL ALSO INCREASE
TUESDAY NIGHT AS A SURFACE PRESSURE GRADIENT BUILDS, WITH RIDGE
WINDS POSSIBLE GUSTING OVER 100 MPH BY MIDNIGHT. SOUTHWEST WINDS AT
THE SURFACE WILL ALSO CONTINUE TO STRENGTHEN OVERNIGHT WITH THE
BULK OF THE SYSTEM IMPACTING THE REGION WEDNESDAY. LABELLE

LONG TERM...WEDNESDAY THROUGH SATURDAY...
MEDIUM RANGE MODELS REMAIN CONSISTENT WITH THE STORM SYSTEM
AFFECTING THE REGION WEDNESDAY. MODEL QPF HAS INCREASED FROM
PREVIOUS RUNS WITH OPERATIONAL MODELS AND MOST GEFS ENSEMBLE
MEMBERS BRINGING COLD AIR INTO THE REGION FAIRLY EARLY WITH THE
SYSTEM. AHEAD OF THE SYSTEM GUSTY WINDS WILL DEVELOP WITH MODELS
SHOWING H700 WINDS IN THE 50-60 KT RANGE EARLY WEDNESDAY. THESE
WINDS WILL DECREASE LATE WEDNESDAY WITH THE PASSAGE OF A COLD
FRONT. SNOW LEVELS SHOULD RISE BRIEFLY DURING THE DAY OVER THE FAR
SE PORTIONS OF THE CWA...BUT PCPN WILL BE DELAYED THERE AS WELL.
ELSEWHERE MOST OF THE PCPN WILL FALL AS SNOW OVER THE REGION.

THIS STORM HAS THE POTENTIAL TO PILE UP SOME DECENT SNOWS IN THE
SIERRA...WITH MODEL QPF APPROACHING 0.80 INCHES DURING THE DAY.
SNOW RATIOS ARE LIKELY TO BE QUITE HIGH SO ACCUMULATIONS IN THE
HIGHER ELEVATIONS OF THE SIERRA COULD BE WELL ABOVE A FOOT. BUMPED
UP WINDS AHEAD OF THE SYSTEM AND GIVEN THE AMOUNT CROSS BARRIER
FLOW AND DOWNSLOPE POTENTIAL...WIND ADVISORIES WILL LIKELY BE
NEEDED ACROSS WESTERN NEVADA AND PARTS OF FAR EASTERN CA...WITH
THE POTENTIAL FOR LOW END HIGH WIND WARNINGS IN THE LEE OF THE
SIERRA. ALL THIS WILL COME INTO BETTER FOCUS AS WE GET CLOSER TO
THIS EVENT...SO NO WATCHES WILL BE ISSUED YET.

BEYOND WEDNESDAY NW FLOW ALOFT DEVELOPS WITH A WEAK SYSTEM DROPPING
SE THROUGH THE FLOW FOR THURSDAY. WITH COLD AIR IN PLACE THIS WOULD
BE MAINLY A SNOW EVENT AS WELL...BUT AMOUNTS WOULD BE MUCH LESS
THAN WEDNESDAY. FOR NOW HAVE KEPT POPS FAIRLY LOW WITH THIS EVENT.
FINALLY...THE OPERATIONAL MODELS BRING ONE LAST WEAK SYSTEM INTO
THE REGION FOR FRIDAY. GEFS ENSEMBLE MEMBERS ALSO SHOW CONTINUED
TROUGHINESS OVER THE REGION. THIS HAS THE LOOK OF A WEAK SLIDER
TYPE SYSTEM. POSITIONING OF THE TROUGH IS IMPORTANT TO LOCATION
OF BETTER CHANCES OF PCPN. GIVEN SOME DISCREPANCIES IN MODEL
SOLUTIONS WILL KEEP MOST OF THE REGION DRY FRIDAY. HOPEFULLY THE
THURSDAY AND POTENTIAL FRIDAY SYSTEMS WILL START TO SHOW BETTER
CONSISTENCY IN THE NEXT COUPLE OF DAYS.

MODELS IN BETTER AGREEMENT THAT RIDGE BEGINS BUILDING SATURDAY
PRODUCING DRYING CONDITIONS AND WARMING TEMPERATURES. MLF

AVIATION...
WEAK SHORT WAVE RIDGE OVER THE REGION EARLY TODAY WILL GIVE WAY TO
AN APPROACHING AREA OF LOW PRESSURE TONIGHT AND INTO MONDAY. BEST
CHANCES FOR PRECIPITATION WILL BE OVER THE SIERRA AND FAR NORTHERN
AREA LATE TONIGHT...SPREADING INTO WESTERN NEVADA ON MONDAY. VFR
CONDITIONS EXPECTED THROUGH ROUGHLY 27/04 UTC...THEN CIGS WILL BEGIN
TO DROP IN THE SIERRA WITH OCCASIONAL IFR CIGS/VSBYS IN SNOW SHOWERS
AFTER 27/12 UTC. EAST OF THE SIERRA CIGS WILL STAY AOA 5000 FT
BEFORE FALLING TO MVFR AFTER 27/15 UTC AS SNOW SHOWERS DEVELOP IN
THE WESTERN GREAT BASIN. BRIEF PERIODS OF CIGS/VSBYS AOB 2000/2
ARE POSSIBLE AT KRNO/KMMH AFTER 27/18 UTC. MLF
