AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
235 PM PST TUE JAN 8 2008

.SYNOPSIS...SCATTERED SHOWERS WILL DIMINISH OVERNIGHT WITH THE NEXT
SYSTEM EXPECTED TO BRING RAIN AND HIGH ELEVATION SNOW BACK TO THE
REGION LATE WEDNESDAY.  A WEAKER SYSTEM MAY BRING A FEW LIGHT
SHOWERS TO AREAS NORTH OF THE CAPE FRIDAY NIGHT AND EARLY SATURDAY.
THEREAFTER HIGH PRESSURE BUILDS IN WITH WARMER AND DRIER WEATHER.

&&

.DISCUSSION...PRECIPITATION IS ON THE DOWNSWING THIS AFTERNOON,
AFTER 1.02 INCHES FELL AT THE WEATHER OFFICE IN EUREKA TODAY.  MOST
GAGES RECEIVED BETWEEN ONE HALF AND TWO INCHES FROM THIS EVENT,
WITH SNOWFALL AMOUNTS UP TO A FOOT REPORTED ALONG HIGHWAY 299 IN
TRINITY COUNTY TODAY.  PRECIPITATION WILL GRADUALLY END OVERNIGHT
WITH ONLY A COUPLE OF INCHES OF ADDITIONAL SNOW ACCUMULATION OVER
THE MOUNTAINS.

SHORTWAVE RIDGING WILL TEMPORARILY BUILD OVER THE REGION EARLY
WEDNESDAY BUT BOUNTIFUL MOISTURE OFF THE PACIFIC WILL OVERRUN A WEAK
WARM FRONTAL BOUNDARY LATE IN THE DAY, BRINGING THE CHANCE OF RAIN
BACK TO THE AREA.  MOST OF THIS WILL BE NORTH OF THE CAPE AND ALONG
THE COAST.  THIS SYSTEM OCCLUDES WEDNESDAY NIGHT WITH THE MAIN
FRONTAL BOUNDARY CROSSING THE FORECAST AREA.  THIS WILL ENSURE A
VERY HIGH PROBABILITY OF RAIN FOR ALL AREAS WITH AMOUNTS BETWEEN 1/2
AND ONE AND A HALF INCHES.  SNOW LEVELS ARE ONCE AGAIN A DIFFICULT
PROPOSITION WITH THIS SYSTEM, BUT ANOTHER 4 TO 8 INCHES OF SNOW IS
POSSIBLE IN TRINITY COUNTY ABOVE 4000 FEET WITH A COUPLE OF INCHES
DOWN TO THE VALLEY FLOORS.  MODEL SOLUTIONS HAVE BEEN MORE
AGGRESSIVE IN HANGING UP ANOTHER FRONT ALONG THE COAST FRIDAY NIGHT
AND SATURDAY SO HAVE BUMPED UP POPS A BIT.  THIS DOES NOT LOOK LIKE
A HEAVY PRECIPITATION PRODUCER, HOWEVER.  THE AWAITED TREND TOWARDS
DRIER AND MILDER WEATHER STILL LOOKS INTACT FOR EARLY NEXT WEEK AS
HIGH PRESSURE BUILDS OVER STATE.  BURGER

&&

.AVIATION...POST-FRONTAL RAIN AND SNOW SHOWERS WILL CONTINUE THIS
EVENING AND TAPER OFF TONIGHT. THE SHOWERS WILL FIRST EASE ALONG
COASTAL REGIONS EARLY THIS EVENING...AND OVER INTERIOR REGIONS LATE
THIS EVENING. MOIST SURFACE CONDITIONS...PARTIAL CLEARING ...AND A
DECREASE IN WINDS WILL SUPPORT THE DEVELOPMENT OF PATCHY FOG
TONIGHT. MAINLY VFR CONDITIONS WITH IFR VISIBILITIES AND CEILINGS
WITH THE FOG AND THE HEAVIER SHOWERS. TH

&&

.MARINE...WITH A BREAK BETWEEN LOW PRESSURE SYSTEMS...THE WINDS WILL
EASE TONIGHT TO BELOW ADVISORY CRITERIA. SOUTHERLY WINDS WILL
INCREASE WEDNESDAY AFTERNOON AHEAD OF THE NEXT FRONTAL SYSTEM THAT
WILL MOVE ACROSS THE WATERS WEDNESDAY NIGHT. EXPECT GALE FORCE WINDS
OVER THE NORTHERN WATERS WEDNESDAY EVENING AS THE FRONT NEARS THE
COAST. A SERIES OF STORMS MOVING ACROSS THE NORTHEAST PACIFIC
THROUGH THE WEEK WILL MAINTAIN HAZARDOUS SEAS THROUGH THE WEEK. TH
