AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
910 AM PST THU JAN 24 2008

.DISCUSSION...WATER VAPOR IMAGERY CONTINUES TO SHOW AN UPPER LEVEL
LOW SPINNING ALONG THE CENTRAL CALIFORNIA COAST...WITH TWO SEPARATE
PIECES OF ENERGY ROTATING AROUND THIS LOW.  WATER VAPOR IMAGERY ALSO
SHOWS A SECONDARY SYSTEM DROPPING SOUTH ALONG 130 WEST.  THIS
SECONDARY SYSTEM LOOKS AS THOUGH IT WILL HELP LIFT THE UPPER LEVEL
LOW ACROSS NORTHERN CALIFORNIA TODAY AND TONIGHT.  HOWEVER...THIS
SECONDARY LOW WILL THEN REPLACE THE FIRST SYSTEM OFF THE
COAST...BRINGING MORE RAIN AND SNOW TO THE REGION THROUGH THIS
WEEKEND.

IN THE MEANTIME...RADAR IMAGERY SHOWS TWO MAIN AREAS OF SHOWERS
FALLING.  THE FIRST BAND OF PRECIPITATION IS LOCATED ACROSS THE
NORTH AND NORTHWEST PORTION OF THE STATE...AND IS RESPONSIBLE FOR
THE RAIN AND SNOW MIX REPORTED AROUND 800 FEET IN THE NORTHERN
SACRAMENTO VALLEY THIS MORNING.  THE SECONDARY BAND IS NOW MOVING
INTO THE CENTRAL COAST.  BETWEEN THESE TWO BANDS...LINGERING SHOWERS
REMAIN...GIVING THE REGION SOMEWHAT OF A BREAK THIS MORNING.
CURRENTLY...SNOW LEVELS ARE RANGING BETWEEN 1000 AND 2000
FEET...WITH SNOW REPORTS FROM PARADISE TO PLACERVILLE TO JACKSON
THIS MORNING.  CAMINO ALSO REPORTED 3 INCHES OF NEW SNOW...WITH AN
INCH AND A HALF IN BURNEY AND PARADISE.  THEREFORE...THE CURRENT
SNOW ADVISORIES FOR THE FOOTHILLS AND SIERRA LOOK ON TRACK FOR
TODAY.  HOWEVER...AM SOMEWHAT CONCERNED ABOUT THE COASTAL RANGE AND
LAKE COUNTY...AS COLD AIR REMAINS IN PLACE OVER THESE AREAS.
THEREFORE...WILL CONTINUE TO WATCH THESE AREAS AS THE SECONDARY BAND
LIFTS NORTH...AS A SNOW ADVISORY MAY BE NEEDED FROM THEM AS WELL.
THERE IS ALSO A SLIGHT CHANCE OF THUNDERSTORMS POSSIBLE IN THE
SOUTHERN SACRAMENTO AND NORTHERN SAN JOAQUIN VALLEYS AS WELL AS THE
DELTA TODAY...AS THE CENTER OF THE UPPER LEVEL LOW MOVES ONSHORE.
CURRENT FORECAST LOOKS ON TRACK AND MENTIONS THIS THREAT AS WELL.
THEREFORE...NO UPDATES ARE PLANNED AT THIS TIME.  PALMER

.PREVIOUS EXTENDED DISCUSSION  (SUNDAY THROUGH THURSDAY)...
WET COOL PATTERN CONTINUES INTO MONDAY. THEN MOST AREAS IN THE
REGION WILL HAVE ABOUT A 12-18 HR BREAK IN THE PRECIPITATION
ANYWHERE FROM MONDAY AFTN THROUGH LATE TUESDAY.  THE LOW OFF THE
CENTRAL CAL COAST WILL FILL AND OPEN UP AS IT MIGRATES NORTHEAST.
THIS IN RESPONSE TO AN UPPER LEVEL TROUGH PUSHING TO INTO CAL FROM
THE GULF OF ALASKA.  THE NAM HAS BEEN THE BIG OUTLIER AS PLACES THE
LOW NEAR THE DELTA AREA SUNDAY MORNING...HOWEVER THE GFS HAS HAD THE
SFC LOW OFFSHORE FILL ABOUT 3MB AND MOVED 200 MILES NORTHEAST CLOSER
TO THE COAST FROM THE 00Z GFS TO THE 06Z RUN.  THE LOWS ARE STILL
ABOUT 200 MILES APART.  OBVIOUSLY...THE PROXIMITY OF THE LOW TO THE
COAST WILL DETERMINE THE PRESSURE GRADIENT AND WINDS.   THE TROUGH
WILL PUSH THROUGH SUNDAY BRINGING SNOW LEVELS DOWN TO AROUND 2000 TO
3000 FT BY MONDAY MORNING. TROUGH PASSING TO THE EAST WILL CONTINUE
A CHANCE OF SHOWERS INTO MONDAY...BUT MUCH OF THE PRECIPITATION WILL
BE OUT OF THE FORECAST AREA BY LATE MONDAY. NORTHWEST FLOW
WILL BRING SHORTWAVE ENERGY TUESDAY AND WEDNESDAY INTO THE REGION
WITH FURTHER CHANCES OF RAIN AND SNOW BEFORE A SHORT BREAK BEFORE
ANOTHER TROUGH PUSHES INTO THE NW CAL THURSDAY AFTN.
