AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
332 PM PDT WED OCT 1 2014

.SYNOPSIS...A DRYING AND WARMING TREND WILL CONTINUE TODAY THROUGH
THE END OF THE WEEK AS A STRONG RIDGE OF HIGH PRESSURE BUILDS
ACROSS THE REGION.

&&

.DISCUSSION...HIGH PRESSURE AND OFFSHORE FLOW THIS AFTERNOON
CONTINUES TO BRING MOSTLY CLEAR SKIES AND DRY CONDITIONS ACROSS
THE REGION. THERE WERE A FEW AREAS OF FOG IN THE EEL RIVER
VALLEY THIS MORNING...BUT THESE DISSIPATED FAIRLY QUICKLY. WITH
THE CLEAR SKIES THE VALLEYS SAW GOOD RADIATONAL COOLING AND
TEMPERATURES DROPPED INTO THE LOW TO 40S ACROSS MUCH OF THE AREA.
IN TRINITY COUNTY A FEW AREAS DROPPED BELOW 36 DEGREES AND LIKELY
SAW FROST. THE HAYFORK RAWS DROPPED TO 35 DEGREES.

TONIGHT CONDITIONS WILL BE FAIRLY SIMILAR IN MOST AREAS.
TEMPERATURES ALOFT WILL WARM A BIT AND THIS SHOULD WARM THE RIDGES
A BIT...HOWEVER CONDITIONS SHOULD BE EVEN BETTER FOR RADIATIONAL
COOLING IN THE VALLEYS. LOW TEMPERATURES WILL BE FAIRLY SIMILAR
AGAIN TONIGHT WITH WIDESPREAD LOWS IN THE 40S IN MOST AREAS.
HAYFORK AND POSSIBLY OTHER COLD VALLEYS IN TRINITY COUNTY WILL
LIKELY SEE SOME FROST AGAIN SO WILL ISSUE ANOTHER FROST ADVISORY.
COASTAL AREAS AND THE EEL RIVER VALLEY MAY SEE A BIT OF PATCHY FOG
AGAIN...HOWEVER THIS SHOULD BE FAIRLY MINIMAL AND DISSIPATE
QUICKLY LIKE TODAY.

THURSDAY AND FRIDAY HIGH TEMPERATURES WILL CONTINUE TO WARM AS
THE RIDGE BUILDS IN OVERHEAD. WINDS WILL CONTINUE TO
DIMINISH...ALTHOUGH FLOW WILL REMAIN WEAKLY OFFSHORE. THIS WILL
LIKELY ALLOW TEMPERATURES TO WARM AT THE COAST WITH TEMPERATURES
INTO THE 70S POSSIBLE ALL THE WAY TO THE COAST. OFFSHORE FLOW WILL
KEEP THE COASTAL AREAS MAINLY CLEAR. THERE IS A CHANCE FOR SOME
GROUND FOG EACH NIGHT...BUT THIS SHOULD BE FAIRLY MINIMAL. FROST
OVER TRINITY COUNTY IS POSSIBLE ONCE AGAIN...ALTHOUGH THIS WILL
NEED TO BE MONITORED.

DRY AND MAINLY SUNNY CONDITIONS ARE EXPECTED THROUGH THE WEEKEND.
NIGHTS WILL BE CHILLY WITH WARM AFTERNOONS INLAND. TEMPERATURES
WILL CONTINUE TO BE 5 TO 15 DEGREES ABOVE NORMAL EACH AFTERNOON.
EARLY NEXT WEEK THE RIDGE WILL START TO BREAK DOWN AND HEIGHTS
ALOFT WILL BEGIN TO FALL. THIS WILL ALLOW TEMPERATURES TO COOL
INLAND...HOWEVER NO PRECIP IS EXPECTED THROUGH WEDNESDAY. AT SOME
POINT THIS WILL LIKELY BRING A RETURN OF COASTAL CLOUDS ALTHOUGH
MODELS ARE GENERALLY KEEPING THE COAST CLEAR THROUGH EARLY NEXT
WEEK. THESE CLEAR SKIES MAY ALLOW FOR SOME FROST ACROSS INLAND
VALLEYS AS THE TEMPERATURES ALOFT START TO COOL AND THINGS REMAIN
CLEAR AND DRY. MKK

&&

.AVIATION...A RIDGE JUST OFF OF THE COAST WILL DOMINATE THE WEATHER
PATTERN. ALONG THE COAST...EXPECT VFR TO PREVAIL. GUSTY NORTH WINDS
THIS AFTERNOON AND EARLY EVENING WILL GO LIGHT AND VARIABLE BY MID
TO LATE EVENING. INLAND...EXPECT VFR TO PREVAIL AS WELL.

&&

.MARINE...AFTERNOON BUOY OBSERVATIONS SHOWED SEA HEIGHTS RANGING
FROM 8-11 FT WITH DOMINANT PERIODS NEAR 11 SECONDS. CDIP BUOYS
SHOWED MOST ALL THE WAVE ENERGY SKEWED TOWARD SHORT PERIOD BANDS OF
12-10, 10-8, 8-6 AND 6-2 SECONDS. EVEN THOUGH WINDS HAVE BEEN
SLIGHTLY LESS NEAR SHORE TODAY, IT IS STILL QUITE ROUGH A FEW MILES
OUT. THUS THE WARNING FOR SEAS AND THE ADVISORY FOR WINDS LOOK ON
TRACK. A THERMAL TROUGH ALONG THE CALIFORNIA COAST WILL BUILD
TONIGHT INTO THU AND WINDS AND SEAS WILL TREND DOWNWARD. THE
DOWNWARD TREND WILL CONTINUE INTO FRI. EXPECT WINDS TO TREND UP
THIS WEEKEND, MAINLY ACROSS THE OUTER WATERS.

&&

.FIRE WEATHER...GUSTY WINDS AND OFFSHORE FLOW WILL CONTINUE
TONIGHT...ALBEIT WEAKER THAN LAST NIGHT. HIGH TEMPERATURES ALOFT
WILL WARM A BIT TONIGHT AND RH RECOVERIES WILL BE POOR IN THE
HIGH ELEVATIONS. WILL CONTINUE TO HEADLINE AS IT APPEARS WINDS MAY
PERSIST A BIT LONGER THAN PREVIOUSLY EXPECTED. THE AREA WILL
CONTINUE TO DRY AND WARM AS THE HIGH PRESSURE BUILDS IN OVER THE
PACIFIC NORTHWEST THROUGH THE NEXT FEW DAYS. RECOVERIES WILL BE
VERY POOR OVER THE HIGHER ELEVATIONS ALTHOUGH VALLEYS AND NORTH
SLOPES WILL SEE MUCH BETTER RECOVERIES. MKK

&&
