AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
950 AM PST THU MAR 2 2006
UPDATE...LIGHT TO MODERATE SNOW FALLING ALONG NEARLY
STATIONARY FRONTAL BAND ACROSS NRN SIERRA THIS MORNING.
AROUND 4 TO 8 INCHES OF NEW SNOW REPORTED BY SPOTTERS
AROUND LAKE TAHOE AND TRUCKEE AREA AS OF 9 AM THIS
MORNING. SNOW SPILLING OVER MAINLY ACROSS NRN VALLEY OF
WRN NV N OF I80 WITH AN INCH OR TWO REPORTED IN COLD
SPRINGS AND NWD INTO NRN WASHOE COUNTY. IMPRESSIVE AMOUNT
OF COLD AIR CONVECTION UNDER COLD POOL ALONG OFF NRN CA CST
WITH SOME LIGHTNING DETECTED OFF COAST N OF BAY AREA.
SHOULD SEE STEADY LIGHT TO MODERATE SNOW AND SNOW SHOWERS
IN SIERRA TODAY AND THIS EVENING THEN INCREASING ON FRIDAY
AS UPPER TROUGH AND COLD POOL SWINGS INLAND. UPDATES THIS
MORNING TO INCREASE SNOW AMOUNTS IN SIERRA ZONES. WILL
BE LOOKING AT EXTENDING WS WARNING INTO FRIDAY NGT WITH
AFTERNOON FORECAST PACKAGE. CYLKE
.LONG TERM...SUNDAY THROUGH WEDNESDAY...
NEXT TROF APPROACHING THE WEST COAST SUNDAY WILL SPREAD PRECIP INTO
NERN CA BY AFTERNOON AND ACROSS THE REMAINDER OF THE SIERRA AND
ADJACENT SECTIONS OF WRN NV SUN NIGHT. THIS SYSTEM IS NOW COMING IN
COLDER AND DEEPER ON THE 00Z AND 06Z GFS...ALTHOUGH THESE
OPERATIONAL RUNS ARE MORE AGGRESSIVE THAN THE ENSEMBLE MEMBERS AND
OTHER MEDIUM RANGE GUIDANCE. MAX SNOW LEVELS ARE NOW EXPECTED ONLY
TO BE NEAR 6500 FT AT THE ONSET SUN AFTN BUT QUICKLY DROP BELOW LAKE
LEVEL SUN EVENING AND THEN SETTLE BETWEEN 4500 AND 5000 FT THRU
MONDAY...RESULTING IN MINIMAL HYDROLOGIC CONCERN. WHILE THE MODEL
DATA HAVE THEIR DIFFERENCES ON THE INTENSITY OF THIS LOW...THERE IS
ENOUGH AGREEMENT THAT SOME PRECIP WILL OCCUR SO POPS WERE NUDGED UP
TO LIKELY VALUES FOR THE SIERRA ZONES SUN NIGHT-MON. WINDS WILL PICK
UP SUN NIGHT-MON MORNING AS THE TROF AND ASSOCIATED COLD FRONT MOVES
ACROSS WRN NV.
NEXT STORM AND COLD FRONT FOLLOWS QUICKLY MON NIGHT-TUES WITH SNOW
LEVELS EASILY DOWN TO THE VALLEY FLOORS OF WRN NV WITH BRISK WINDS
CONTINUING ALTHOUGH SPEEDS SHOULD BE A BIT LOWER THAN MONDAY. POPS
WERE NUDGED UP TO LIKELY VALUES FOR THE SIERRA AND ALSO FOR FAR WRN
NV...AS POTENTIAL FOR ANOTHER HEAVY SNOW EVENT EXISTS INTO THE
RENO-CARSON CITY AREAS. HOWEVER...AFTER SEEING HOW THE GFS CHANGED
IN HANDLING THE SYSTEM ABOUT TO AFFECT THE REGION FROM LAST WEEKEND
DAYS AGO TO THE CURRENT RUN...IT IS TOO SOON TO DETERMINE WHETHER
THIS SYSTEM WOULD PRODUCE HIGH END SNOW AMOUNTS FOR A MARCH STORM IN
PARTS OF WRN NV ESPECIALLY SINCE ACCUMULATION ON VALLEY AREAS IS
MORE DEPENDENT ON THE TIME OF DAY THE HEAVIER SNOW BANDS OCCUR.
PRECIP SHOULD TAPER OFF TUES NIGHT WITH CHILLY TEMPS ACROSS THE
REGION WHICH MAY BE EVEN COLDER IF WIDESPREAD SNOW COVER IS PRESENT
AND CLOUDS HAVE A CHANCE TO THIN OUT. THE NEXT TROF APPROACHES SO
FAST THAT THE OVERRUNNING HIGH CLOUDS MAY ALREADY BE OVER THE REGION
BEFORE THE LOW CLOUDS FROM THE EXITING SYSTEM ARE ABLE TO CLEAR OUT.
CURRENT GFS TIMING BRINGS LIGHT SNOW INTO NERN CA WITH WINDS
INCREASING OVER MUCH OF THE REGION BY WED AFTERNOON. MJD
