AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
330 AM PST SUN FEB 23 2009

.DISCUSSION...
UPPER LEVEL LOW PRESSURE SYSTEM NEAR 42N AND 133W THIS MORNING IS
APPROACHING THE WEST COAST AND THE MOISTURE PLUME IS GRADUALLY
SINKING SOUTH. THE MOISTURE PLUME WITH THE SUBTROPICAL JET WILL MOVE
TO THE SOUTHEAST OF NORTHERN CALIFORNIA TODAY. ANOTHER JET WILL MOVE
INLAND NEAR THE ORCA BORDER AS THE UPPER LEVEL LOW MOVES TO THE
PACIFIC NORTHWEST COAST THIS AFTERNOON AND TONIGHT. THIS WILL
CONTINUE TO BRING PERIODS OF PRECIPITATION TO THE AREA INTO TONIGHT.
ALTHOUGH THE BEST DYNAMICS WITH THIS SYSTEM WILL MAINLY BE
NORTH OF INTERSTATE 80 SO EXPECT PRECIPITATION TO TAPER OFF IN THE
SOUTH MONDAY NIGHT. ALTHOUGH THE PRECIPITATION WILL CONTINUE IN THE
SIERRA DUE TO OROGRAPHICS WITH SOUTHWESTERLY WINDS AT 700 MB INTO
TUESDAY MORNING. SNOW LEVELS ARE GENERALLY AROUND 5500 TO 6500 FEET
TODAY...EXCEPT LOCALLY LOWER SNOW LEVELS ARE POSSIBLE THIS MORNING
IN COLDER MOUNTAIN VALLEYS LIKE CHESTER. THE SNOW LEVELS WILL LOWER
OVERNIGHT TONIGHT TO AROUND 4500 TO 5500 FEET WITH A LITTLE COOLER
AIR MASS MOVING INTO THE AREA. GUSTY SOUTHERLY WINDS UP TO 50 MPH
ARE POSSIBLE OVER THE RIDGES AND UP TO 35 MPH IN THE VALLEY INTO
THIS EVENING WITH THE JET NEAR THE AREA. LINGERING SHOWERS...MAINLY
OVER THE MOUNTAINS ARE EXPECTED TO BECOME MORE SCATTERED DURING THE
DAY ON TUESDAY.  ANOTHER LOW PRESSURE SYSTEM DROPS DOWN OFF THE
COAST OF WASHINGTON ON WEDNESDAY WITH ZONAL FLOW OVER NORTHERN
CALIFORNIA. THIS WILL CONTINUE THE CHANCE OF SHOWERS...MAINLY OVER
THE NORTHERN PORTION OF THE AREA.

.EXTENDED DISCUSSION (THURSDAY THROUGH SUNDAY)...
EXTENDED MODELS CONTINUE TO STRUGGLE WITH DETAILS AND MODEL TO
MODEL/RUN TO RUN CONSISTENCY ALTHOUGH AT LEAST AGREE THAT MOST OF
EXTENDED PERIOD WILL CONTINUE UNSTABLE AND DAMP. MODELS ALL DROP LOW
OUT OF WESTERN CANADA AND INTO NORTHEASTERN PACIFIC EARLY THURSDAY
THEN AS HAS BEEN THE CASE THE LAST FEW DAYS...QUICKLY DIVERGE AFTER
THAT. LATEST 00Z ECMWF RUN WANTS TO MOVE LOW INLAND MORE QUICKLY
THAN PREVIOUS RUN WHICH LINGERED IT OFF THE COAST ON THURSDAY LIKE
CURRENT RUNS OF GFS AND CANADIAN MODELS. ALL MODELS WOULD PULL
SUBTROPICAL MOISTURE NORTHWARD INTO NORCAL FOR FAIRLY WIDESPREAD
PRECIP COVERAGE BUT MORE PROGRESSIVE MOVEMENT OF LATEST ECMWF WOULD
BRING A COLDER MORE DYNAMIC SOLUTION AND HEAVIER PRECIP. 00Z ECMWF
AND 18Z GFS MIGHT HAVE BROUGHT A BRIEF BREAK IN PRECIP WITH BOTH
MODELS MOVING OFFSHORE LOW QUICKLY INLAND AND BRINGING BRIEF
RIDGING. LATEST GFS AND 12Z ECMWF HAVE KEPT A WETTER SOLUTION BY
LINGERING LOW OFFSHORE AND CONTINUING TO PUMP SUBTROPICAL MOISTURE
INTO NORTHERN CALIFORNIA. HAVE GONE WITH CONTINUED CHANCE POPS FOR
FRIDAY TO ACCOUNT FOR EXTREME UNCERTAINTY AND SPLIT DIFFERENCE IN
MODELS FOR SNOW LEVELS. MODELS ACTUALLY COME MORE IN LINE BY THE
WEEKEND WITH GENERAL AGREEMENT IN BRINGING COLD PACIFIC LOW OFF THE
PACIFIC NORTHWEST COAST BY SATURDAY AFTERNOON. BOTH MODELS HINT AT
ANOTHER SUBTROPICAL MOISTURE TAP FOR WET WEATHER PATTERN NEXT
WEEKEND BUT ECMWF DIGS UPPER LOW FARTHER SOUTHWARD FOR A COLDER
SOLUTION. AGAIN WENT WITH AVERAGING APPROACH FOR SNOW LEVELS UNTIL
EXTENDED MODELS CAN COME MORE IN LINE WITH EACH OTHER.

.AVIATION...
UPPER LOW OFF NORCAL COAST CONTINUES TO PULL MOIST SUBTROPICAL AIR
OVER STATE FOR MVFR TO IFR CONDITIONS IN RAIN AND CIGS OVER
INTERIOR NORTHERN CALIFORNIA VALLEY AND IFR/LIFR OMTNS. ISOLATED
THUNDERSTORMS POSSIBLE IN THE VALLEY THIS AFTERNOON. SNOW LEVELS
5000 FEET NORTHERN MOUNTAINS TO 6000 FEET WEST SLOPES OF THE SIERRA
LOWERING TO 4500 TO 5500 FEET BY TUESDAY MORNING.IMPROVING
CONDITIONS TUESDAY AFTERNOON AS UPPER LOW SHIFTS INTO PACIFIC
NORTHWEST WITH DRYING IN THE VALLEY AND ISOLD SHOWERS OVER THE
MOUNTAINS TUESDAY. SOUTHERLY WINDS CONTINUING WITH GUSTS TO 30 MPH
OMTNS AND IN THE NORTHERN SACRAMENTO VALLEY.

.STO WATCHES/WARNINGS/ADVISORIES...
A WINTER STORM WARNING REMAINS IN EFFECT UNTIL 4 AM PST TUESDAY
ABOVE 6500 FEET FROM LASSEN PARK AND WESTERN PLUMAS COUNTY THROUGH
