AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
345 AM PST FRI DEC 26 2008

.SYNOPSIS...NORTHWEST CALIFORNIA WILL BE IN BETWEEN RAIN AND
SNOW MAKING WEATHER SYSTEMS TODAY. A BRIEF BREAK IN RAIN IS
EXPECTED. A NEW FRONTAL SYSTEM OVER THE CENTRAL PACIFIC WILL
BRING INCREASING RAIN TONIGHT THROUGH SUNDAY.

&&

.SHORT TERM...TODAY THROUGH SUNDAY...SHOWER ACTIVITY HAS BEEN
DECREASING THROUGH THE NIGHT...PER RADAR AND SATELLITE IMAGERY.
SURGE OF COLD AIR WILL DIMINISH THIS MORNING...BUT A FEW SHOWERS
MAY STILL COME ASHORE THROUGH ABOUT MID MORNING. OVER-RUNNING CLOUDS
ASSOCIATED WITH A NEW FRONTAL SYSTEM WAS ALREADY CROSSING 130W AS OF
10Z. WARM/MOIST AIR ADVECTION ALONG WITH SOUTH/SOUTHWEST LOW LEVEL
FLOW WILL START TO INCREASE THIS AFTERNOON. WE SHOULD SEE LIGHT
OVER-RUNNING PRECIP DEVELOP OVER THE NORTHERN HALF OF THE FORECAST
AREA IN THE LATE AFTERNOON.

PRECIP COVERAGE AND INTENSITY WILL BE INCREASING OVER THE WEEKEND.
STORM THIS WEEKEND WILL BE WARMER...WITH THE AIR MASS ORIGINATING
FROM THE CENTRAL AND EASTERN PACIFIC OCEAN. HOWEVER...WITH LINGERING
MARITIME POLAR AIR OVER THE REGION...SNOW LEVELS SHOULD INITIALLY

SNOWFALL AS LOW AS 2000 FEET BY EARLY SATURDAY MORNING. WARM AND
MOIST AIR ADVECTION INCREASES OVER THE WEEKEND...AND LEVELS SHOULD

TRANSITION TO A WARMER AIR MASS AND HIGHER SNOW LEVELS WILL TAKE
LONGER ACROSS EASTERN AND CENTRAL TRINITY COUNTY...AND LIGHT SNOW
ACCUMULATIONS MAY CONTINUE AS LOW AS THE 2000 FOOT MARK THROUGH
MIDDAY SATURDAY.

MORE SIGNIFICANT FORECAST ISSUE FOR THIS WEEKEND IS THE POTENTIAL
FOR HEAVY RAIN RATES ACROSS DEL NORTE AND NORTHERN HUMBOLDT
COUNTIES. A NEARLY STATIONARY FRONTAL BOUNDARY WILL SETUP OVER THE
WEEKEND AND SERVE AS THE FOCAL POINT FOR HIGH RAIN RATES ACROSS DEL
NORTE AND NORTHERN HUMBOLDT COUNTIES. NAM12 AND GFS DIFFER ON THE
AMOUNTS AND INTENSITY. FOR NOW WILL LEAN TOWARDS THE WETTER
GFS...WHICH HAS 7 TO 9 INCHES OF RAIN BY 12Z MONDAY ACROSS DEL NORTE
AND NORTHERN HUMBOLDT COUNTIES. FLOODING AND HYDRO IMPACTS CERTAINLY
LOOK POSSIBLE OVER THE WEEKEND. STAY TUNED FOR FURTHER STATEMENTS
AND IMPACTS. MONDAY AND TUESDAY MAY BE QUITE WET AS WELL. THE
CURRENT EXTENDED FORECAST LOOKS REASONABLE...WITH RAIN TAPERING
OFF TO A CHANCE OF SHOWERS ON TUESDAY AS COOLER AIR ARRIVES.
ADJUSTMENTS ARE NOT NECESSARY AT THIS TIME. DJB

.PREVIOUS LONG TERM...SUNDAY NIGHT THROUGH THURSDAY...THE EXTENDED
PORTION OF THE FORECAST PERIOD FEATURES A NEARLY ZONAL FLOW ALOFT
ALONG WITH A COUPLE OF SURFACE FEATURES PASSING THROUGH THE REGION.
ON MONDAY... HPC DEPICTS A SURFACE FRONT MOVING EAST OF THE AREA.
RAIN WILL TAPER OFF TO SHOWERS MONDAY NIGHT...WITH A CHANCE OF
SHOWERS CONTINUING THROUGH TUESDAY.  ANOTHER FRONT IS EXPECTED TO

FEET THROUGH THE EXTENDED PERIOD. KL
