AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
522 AM PDT TUE NOV 1 2011

.SYNOPSIS...DRY AND MOSTLY CLEAR WEATHER WILL PERSIST TODAY
THROUGH WEDNESDAY MORNING UNDER LIGHT OFFSHORE FLOW. A COLD
UPPER TROUGH WILL APPROACH THE COAST LATE ON WEDNESDAY AND BRING
A CHANCE OF RAIN AND HIGH ELEVATION SNOW BY THURSDAY MORNING.
ANOTHER COLD TROUGH IS EXPECTED OVER THE WEEKEND.

&&

.DISCUSSION...SKIES WERE CLEAR ACROSS THE FORECAST REGION EARLY
THIS MORNING EXCEPT IN THE EEL AND VAN DUZEN WHERE SOME LOW CLOUDS
WERE APPARENT ON SATELLITE IMAGERY. THESE CLOUDS SHOULD DISSIPATE
RAPIDLY WITH HEATING AND BRISK NORTH WINDS. TEMPERATURES WERE ON
THE CHILLY SIDE FOR MOST PART...BUT THE NORTH WINDS HAVE KEPT TEMPS
FROM FALLING AT PLACES LIKE CRESCENT CITY AIRPORT AND PT ARENA C-MAN
STATION. THE NORTH WINDS SHOULD DIE DOWN TONIGHT AS HIGH PRESSURE
MOVES INTO THE GREAT BASIN AND WINDS SHIFT AROUND TO THE EAST. NO
DOUBT GUSTY EASTERLIES WILL DEVELOP OVER THE EXPOSED RIDGES TONIGHT
BUT FOR THE MOST PART...WINDS WILL BE LIGHT OR CALM IN THE VALLEYS.
WITH DRY AIR...CLEAR SKIES AND CALM WINDS EXPECT FROST TO DEVELOP
BY EARLY WED. THUS HOISTED A FROST ADVISORY FOR COASTAL AREAS.

AFTER A COOL AND CRISP MORNING ON WED...EXPECT IT WILL ANOTHER
FINE DAY AS A FRONT APPROACHES THE COAST. HIGH CLOUDS SHOULD INVADE
THE SKIES...BUT IT LOOKS LIKE THICK AND RAIN BEARING CLOUDS WILL
HOLD OFF TIL WED NGT. FRONTAL PASSAGE TIMING IS STILL A LITTLE
SKETCHY. GFS WAS A TAD FASTER WITH PRECIP GENERATION FROM THE
FRONT THAN THE NAM12. THE NAM12 STILL HAS RAIN BY 5 AM THU ACROSS
THE NORTHERN HALF OF THE DISTRICT AND BY 11 AM SOUTH.

A COLD UPPER TROUGH WILL FOLLOW ON THU. THIS TROUGH HAS DECENT
DYNAMICS AND COLD AIR ALOFT BUT NOT MUCH IN THE WAY OF MOISTURE.
WE SHOULD SEE NUMEROUS OR SCATTERED SHOWERS ON THU IN THE COOL
AND WEAKLY UNSTABLE AIR BEHIND THE FRONT. SNOW LEVELS WILL FALL
TO 4000-4500 FEET BUT ACCUMULATION WILL MOST LIKELY BE LIGHT.
WITH 500MB TEMPS PLUNGING TO -30C ON THU...SUSPECT WE MAY SEE
ISOLATED LOW TOP TSTMS OVER THE WATERS.

SOLUTIONS APPEARED TO BE IN GOOD AGREEMENT ON MOVING THE
UPPER TROUGH EAST BY FRIDAY MORNING. THUS WENT MOSTLY DRY ON
FRI EXCEPT ALONG THE NORTH COAST WHERE A FEW LINGERING SHOWERS MAY
CREEP ONSHORE. NEXT SYSTEM SHOULD TAKE AIM ON THE REGION SATURDAY
INTO SATURDAY NIGHT. THIS STORM APPEARS TO HAVE SLIGHTLY MORE
MOISTURE AND MAY END UP BRING MORE RAIN THAN THE FIRST.

LA NINA WEATHER PATTERN DOES NOT CHANGE MUCH NEXT WEEK. SO
SUSPECT WE WILL CONTINUE TO SEE PERIODIC RAIN OR SNOW. LATEST
GFS HAS THE NEXT ONE AFFECTING NW CA WITH MORE PRECIP ON TUE
OR TUE NIGHT NEXT WEEK. THE ECMWF WAS NOT IN SYNC HOWEVER.
TIMING IS STILL DUBIOUS...BUT I DID BEEF UP THE PRECIP CHANCES
ABOVE CLIMO ON TUE.

&&

.AVIATION...MOSTLY CLEAR SKIES ARE EXPECTED TO PREVAIL THRU THIS TAF
CYCLE. GUSTY WINDS WILL CONTINUE AT COASTAL LOCATIONS THRU MOST OF
THE DAY. INCLUDED LLWS AT KCEC EARLY THIS MORNING FOR PERIODS WHERE
SFC WINDS PARTIALLY DECOUPLE FROM STRONG BOUNDARY LAYER WINDS. /SEC

&&

.MARINE...N GALES ARE EXPECTED TO CONTINUE INTO THE EVENING OVER THE
OFFSHORE WATERS WITH OCCASIONAL GUSTS TO GALE FORCE. WINDS AND SEAS
WILL SUBSIDE LATER TONIGHT. HAVE LEFT EXISTING HEADLINES UNCHANGED.
NW SWELLS ARE EXPECTED TO INCREASE LATER IN THE WEEK WITH HEIGHTS OF
14 TO 15 FT POSSIBLE. /SEC

&&

.EKA WATCHES/WARNINGS/ADVISORIES...SMALL CRAFT ADVISORY UNTIL 4 PM
PDT THIS AFTERNOON PZZ450-455. HAZARDOUS SEAS WARNING UNTIL 9 PM
PDT THIS EVENING PZZ450-455. GALE WARNING UNTIL 9 PM PDT THIS
