AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
603 PM PST TUE DEC 13 2011

.SYNOPSIS...A RIDGE OF HIGH PRESSURE IS CURRENTLY OVER THE AREA. A
WEAK WEATHER SYSTEM WILL MOVE OVER THE AREA LATE WEDNESDAY NIGHT
AND THURSDAY MORNING BRINGING RAIN AND SNOW TO THE REGION. HIGH
PRESSURE WILL RETURN BEHIND THIS SYSTEM.

&&

.UPDATE...SATELLITE SHOWS CLOUDS THICKENING ALONG THE NORTHWEST
CALIFORNIA COAST. UPDATED THE FORECAST TO INCREASE CLOUD COVER IN
THESE AREAS AND TO REMOVE THE FROST.

&&

.PREV DISCUSSION... /ISSUED 326 PM PST TUE DEC 13 2011/

.SHORT TERM...MOSTLY CLEAR SKIES ACROSS THE REGION WITH THE
EXCEPTION OF SOME LOW CLOUDS ALONG THE COAST. SUSPECT THESE CLOUDS
ARE CAUSED BY THE LOW PRESSURE PASSING BY OFFSHORE. AS THIS LOW
PRESSURE CONTINUES TO DIVE SOUTH EXPECT THESE LOW CLOUDS WILL
CLEAR AFTER MIDNIGHT...ALTHOUGH CONFIDENCE IS LOW THIS. EITHER WAY
AS THE RIDGE BUILDS IN BACK IN TOMORROW SKIES ARE EXPECTED TO
CLEAR IN THE MORNING BRIEFLY. WEDNESDAY NIGHT INTO THURSDAY
MORNING ANOTHER SYSTEM IS EXPECTED TO BRING THE FIRST RAIN OF THE
MONTH TO THE AREA. MODELS REMAIN IN GOOD AGREEMENT ON THE TIMING
OF THIS SYSTEM. RAINFALL AMOUNTS LOOK TO RANGE FROM 0.10 TO 0.20
IN MOST AREAS TO OVER A HALF INCH IN THE MOUNTAINS OF DEL NORTE
COUNTY. SNOW LEVELS LOOK TO BE AROUND 4000 FEET BUT COLD AIR
TRAPPED IN WEAVERVILLE AND TRINITY CENTER AREAS COULD RESULT IN
LIGHT SNOW TO VALLEY FLOORS THUR MORNING. IF SNOW DOES MAKE IT TO
THE VALLEY FLOORS EXPECTED THERE WILL BE LITTLE TO NO
ACCUMULATION.

.LONG TERM...BEHIND THE SYSTEM ON THURSDAY AFTERNOON MODELS BUILD
THE RIDGE BACK IN QUICKLY. LOWERED POPS THURSDAY AFTERNOON AS IT
APPEARS THE MAJORITY OF THE RAIN WILL BE WITH THE INITIAL FRONT IN
THE MORNING. MODELS ARE STILL SHOWING A SIGNIFICANT WARM UP WITH
THIS RIDGE. CURRENTLY HAVE SKIES MAINLY CLEAR ALONG THE
COAST...BUT CONFIDENCE IS LOW IN THIS AS THE WARMER TEMPERATURES
MAY HELP CREATE A MARINE LAYER. SUNDAY MODELS ARE CONTINUING TO
HINT AT ANOTHER SYSTEM. THE GFS HAS BEEN VERY INCONSISTENT RUN TO
RUN AND AND WITH THE OTHER MODELS. THE ECMWF HAS BEEN SOMEWHAT
MORE CONSISTENT KEPT IN KEEPING THE SYSTEM FARTHER NORTH AND
SLIGHTLY SLOWER. THE 18Z GFS NOW HAS COME MORE INTO LINE WITH THE
ECMWF ON A SLOWER AND WEAKER SOLUTION WHICH BRINGS SOME VERY LIGHT
PRECIP IN SUNDAY AFTERNOON AND EVENING. FOR NOW HAVE SLIGHT CHANCE
POPS IN FROM AROUND SATURDAY NIGHT THROUGH TUESDAY IN THE NORTHERN
PORTION OF THE AREA. THIS WILL NEED TO BE MONITORED IN FUTURE
FORECASTS. MKK

&&

.AVIATION...POTENTIALLY TRICKY FORECAST TONIGHT COMPARED TO THE
LAST COUPLE OF NIGHTS. STRATUS HAS BEEN LURKING OFFSHORE ALL DAY
AND RESULTED IN A BRIEF CIG AT KACV. THE BULK OF THE LOW CLOUDS
OFFSHORE IS ASSOCIATED WITH LOW PRESSURE TRACKING SOUTHWARD WELL
OFFSHORE OF THE CALIFORNIA COAST. MEANWHILE LOW CLOUDS APPEAR TO
BE BANKING UP AGAINST A WEAKER TROUGH AXIS 10-20NM
OFFSHORE...WHILE LOCALLY CONGREGATING AROUND CAPE MENDOCINO. SOME
CUMULUS HAS DEVELOPED ACROSS THE HILLS SURROUNDING HUMBOLDT AND
ARCATA BAY. WE ARE THINKING THAT SCT TO BKN CIGS 500-1000FT WILL
IMPACT KACV FOR A TIME THIS EVENING BEFORE THE FLOW TENDS MORE
OFFSHORE LATER TONIGHT. KCEC SHOULD STAY CLEAR ALTHOUGH SOME FOG
CANNOT BE RULED OUT COMPLETELY. KUKI SAW SOME BRIEF IFR FOG THIS
MORNING AND THERE MAY BE SOME MORE WEDNESDAY MORNING...BUT NOTHING
PARTICULARLY PERSISTENT OR DENSE IS EXPECTED.

&&

.MARINE...WINDS ARE LIGHT...MAINLY UNDER 15KTS ACROSS THE WATERS
TODAY AND TENDING ONSHORE THIS AFTERNOON ACROSS THE INNER WATERS.
WINDS WILL TEND SOUTHERLY ON WEDNESDAY AHEAD OF AN APPROACHING
FRONT BUT ARE EXPECTED TO REMAIN LIGHT. AS THE FRONT MOVES THROUGH
DURING THE PREDAWN HOURS THURSDAY THERE MAY BE A PERIOD OF
STRONGER WINDS POTENTIALLY BRIEFLY REACHING 25KT NORTH OF CAPE
MENDOCINO. NORTHERLIES WILL RETURN FOR FRIDAY AND FRIDAY NIGHT
WHICH MAY REQUIRE A SCA FOR THE OUTER WATERS. AN 8FT AT 12 SECOND
SWELL WILL ARRIVE BY WEDNESDAY NIGHT WITH THE FRONT THEN GRADUALLY
SUBSIDE HEADING INTO FRIDAY. A MORE SUBSTANTIAL NW SWELL WILL
ARRIVE FOR THE WEEKEND.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...

CA...NONE.

NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
