AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
1010 AM PST FRI MAR 3 2006

.SYNOPSIS...A WEATHER SYSTEM MOVING THROUGH THE WESTERN UNITED STATES
WILL BRING SIGNIFICANT SNOW AND RAIN TO THE GREAT BASIN THROUGH
SATURDAY MORNING. AFTER A DRY SUNDAY...ANOTHER WEATHER SYSTEM MOVING
INTO THE PACIFIC NORTHWEST WILL BRING MORE UNSETTLED WEATHER TO THE
REGION NEXT WEEK.
&&

.UPDATE...WINDS AHEAD OF COLD FRONT BLOWING 30 TO 40 MPH WITH GUSTS
NEAR 50 MPH ACROSS CNTRL NV. ISSUED A WIND ADVISORY UNTIL 3 PM FOR
THAT AREA. WINDS WILL THEN DIMINISH BEHIND COLD FRONT. CEC
&&

.PREV DISCUSSION...130 AM. ACTIVE. NEXT SYSTEM JUST OFF OF CA COAST
ATTM WILL MOVE ONSHORE EARLY THIS MORNING. ALSO HAVE SFC FRONT FROM
WX DISTURBANCE THAT BRUSHED NW NV THURSDAY STILL ALONG THE NRN CA/NV
BORDER WHICH HAS BEEN A FOCUSING MECHANISM FOR PRECIP SO FAR TONIGHT.
AS TODAY PROGRESSES...WILL SEE MAIN H5 LOW MOVE INTO NRN CA WHILE H7
LOW MOVES INTO NW NV THIS AFTERNOON. THIS WILL PUSH SFC COLD FRONT
ACROSS NV TODAY AND EXPECT WARMEST AREAS TO BE ACROSS FAR ERN NV
ALONG UT BORDER TODAY. UPPER JET WILL PUSH THRU CENTRAL NV KEEPING
CWFA IN FAVORABLE LF QUAD OF JET MAX SPOKES. BEST INSTABILITY AND
LLVL LIFT REMAIN ACROSS NRN NV WITH GFS SHOWING BEST DIV/CONV
COUPLETING HERE AS WELL. ALSO OF NOTE IS NEG TILT TO H7 PORTION OF
THIS SYSTEM PLUS STRONG S/WV ENERGY PROGGED HERE AS WELL. WITH VERY
STRONG LAPSE RATES HAVE ALSO ADDED A SLIGHT CHANCE OF THUNDER TO THE
FORECAST FOR TODAY AND TONIGHT ACROSS NRN NV.

AS LLVL PORTIONS OF THIS SYSTEM MOVE ACROSS NRN NV THIS AFTERNOON
EXPECT MAJORITY OF PRECIP TO BEGIN THEN AND SPREAD EAST THRU THE
AFTERNOON. HAVE MADE MODIFICATIONS AND ADDITIONS TO CURRENT SNOW
ADVISORY GIVEN TIMING ASPECTS. WILL SEE PRECIP BEGIN IN HUMBOLDT
COUNTY THIS MORNING WITH LOWER VALLEYS BEING EARLY RAIN/SNOW MIX
BEFORE TRANSITIONING TO ALL SNOW THIS AFTERNOON. RATHER QUICK SYSTEM
AS IT LIFTS INTO SE ID TONIGHT...BUT GIVEN SYNOPTIC PATTERN BELIEVE
DO NOT NEED MUCH TIME...RELATIVELY SPEAKING...TO REACH ADVISORY
CRITERIA AS SNOWFALL RATES WILL BE OVER AN INCH AN HOUR IN SOME
LOCATIONS. EXPECT 2 TO 4 INCHES IN THE VALLEYS WITH 5 TO 7 INCHES IN
THE NORTHERN MTNS BY SAT MORNING. SOME AREAS THAT WILL HAVE ENHANCED
OROGRAPHIC LIFT MAY PUSH HEAVY SNOW CRITERIA...THOUGH BELIEVE
THESE AREAS WILL BE LOCALIZED.

WILL SEE ACTIVITY WANE SAT MORNING AND WILL KEEP LINGERING POPS
ACROSS NE NV THRU THE MORNING. WILL SEE WEAK UPPER RIDGE MOVE ACROSS
THE WRN U.S. ON SATURDAY WITH NEXT SYSTEM MOVING INTO THE ERN PAC OFF
OF NRN CA COAST ON SUNDAY. WILL SEE TEMPS REBOUND OVER THE WEEKEND...
THOUGH BELIEVE MODEL GUIDANCE A LITTLE OPTIMISTIC ON SAT GIVEN H7
TEMPS STILL BELOW -10C FOR MOST OF THE DAY WITH FRESH SNOWPACK ACROSS
THE REGION. HAVE UNDERCUT GUIDANCE VALUES HERE AND SPLIT THE
DIFFERENCE FOR SUNDAY AS MAV VALUES NEARLY 10 DEG COLDER THAN MET
DATA. GIVEN COLD BIAS THAT MAV HAS SHOWN OVER MAJORITY OF THE WINDER
AM LEANING SLIGHTLY TOWARDS MET NUMBERS...BUT WITH SNOWCOVER MAV
VALUES HARD TO THROW OUT. WITH LLVL WARMING WILL SEE TEMPS WARM BACK
TO NEAR NORMAL VALUES ON SUNDAY. FEHRN

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY. MODELS STILL IN DECENT
AGREEMENT THROUGH EARLY PART OF EXTENDED WITH RIDGE AXIS TO OUR EAST
SUNDAY NIGHT AND NEXT PAC SYSTEM MOVING ONSHORE. MODEL TRENDS HAVE
BEEN TO SLOW THE MOVEMENT OF THIS SYSTEM INTO THE GREAT BASIN.
HOWEVER DUE TO INCONSISTENCIES IN TIMING FROM RUN TO RUN...HAVE MADE
LITTLE CHANGE TO PREVIOUS FORECAST. GFS IS SPLITTING ENERGY AND HAS
MAIN UPPER LOW EJECTING NORTHEAST INTO PAC NW MONDAY WITH SECONDARY
PIECE OF ENERGY DIGGING DOWN THE BACKSIDE OF LOW. THE TRACK OF THE
SECONDARY UPPER LOW IS A BIT FURTHER WEST THAN EARLIER RUNS. IT NOW
DIGS THE LOW THROUGH CA MONDAY NIGHT INTO TUESDAY AND BOTTOMS OUT IN
BAJA WED AND THEN MOVES EASTWARD. WHAT REMAINS OF THE UPPER TROUGH
MOVES ACROSS THE GREAT BASIN ON TUESDAY. THIS TRACK IS NOT AS
PROMISING FOR A SIGNIFICANT SNOW EVENT AS PREVIOUS RUNS...BUT STILL
BEARS WATCHING. THIS IS FOLLOWED BY A VERY INTENSE SYSTEM ON
WEDNESDAY THAT DROPS RAPIDLY INTO THE AREA. GFS HAS NEARLY 180KT JET
ASSOCIATED WITH THIS SYSTEM AND 700 MB TEMPS -18C. THE GFS HAS UPPER
THIS UPPER LOW MOVING OVER THE GREAT BASIN AND PERSISTING AT LEAST
THROUGH FRIDAY. THIS COULD BE A SPECIAL HEAVY SNOW EVENT IF THIS
ACTUALLY HAPPENS. WILL CLOSELY MONITOR THIS POSSIBLE SCENARIO. RCS
&&

.AVIATION...VRF CONDITIONS THIS MORNING WILL GIVE WAY TO MVFR AND
OCCASIONAL IFR CONDITIONS THIS AFTERNOON AND EVENING AS A COLD FRONT
MOVES IN FROM THE WEST. THIS COLD FRONT WILL BRING PERIODS OF SNOW
WITH LOW VISIBILITIES AND LOW CEILINGS THROUGH THIS EVENING. THE
WEATHER SYSTEM WILL MOVE EAST OF THE STATE OVERNIGHT WITH IMPROVING
CONDITIONS FROM WEST TO EAST. RCS &&

.HYDROLOGY...RIVER LEVELS EXPECTED TO REMAIN STEADY AHEAD OF NEXT
SYSTEM. HOWEVER...WILL NEED TO MONITOR LEVELS ALONG HUMBOLDT RIVER
OVER NEXT FEW DAYS AS VARIOUS WEATHER SYSTEMS MOVE THROUGH THE
REGION. HUMBOLDT RIVER BETWEEN ELKO AND BATTLE MOUNTAIN OVER PAST 24
TO 36 HOURS HAS BEEN NEAR OR ABOVE MONITORING STAGE WITH CREST NOW
NEAR PALISADE. MAY SEE HUMBOLDT RIVER RISE BACK ABOVE MONITORING
STAGE NEAR AND WEST OF ELKO OVER THE WEEKEND AND WILL MONITOR THE
SITUATION. FEHRN
&&
