AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
820 AM PDT THU APR 1 2010

.SYNOPSIS...WEAK HIGH PRESSURE WILL PROVIDE DRY WEATHER TODAY.
THE NEXT COLD FRONT WILL ARRIVE LATE TONIGHT AND FRIDAY...AND
BRING ANOTHER ROUND OF WIDESPREAD PRECIPITATION.

&&

.UPDATE...HIGH CLOUDS HAVE MOVED OVERHEAD ALLOWING TEMPS TO RISE
ABOVE 35F IN MOST LOCATIONS. THUS WE WILL CANCEL THE FROST ADVISORY
A LITTLE EARLY. NO OTHER CHANGES ANTICIPATED AT THIS TIME. JCA

---------------------PREVIOUS DISCUSSION------------------------

.DISCUSSION...AN UPPER RIDGE HAS PROVIDED MAINLY CLEAR SKIES ACROSS
A GOOD PORTION OF THE FORECAST AREA EARLY THIS MORNING.
TEMPERATURES HAVE RESPONDED ACCORDINGLY...AND CURRENTLY RANGE
THROUGH THE 30S IN MANY AREAS. WE EXPECT SKIES TO REMAIN MOSTLY
CLEAR THROUGH DAYBREAK...BEFORE HIGH CLOUDS GRADUALLY INCREASE
FROM THE NORTHWEST. AS A RESULT...WE HAVE HOISTED A FROST
ADVISORY THROUGH 9 AM THIS MORNING FOR THE REDWOOD COAST (ZONE 1)
AND NORTH COAST INTERIOR (ZONE 3)...WHERE TEMPERATURES OVER AT
LEAST HALF OF THE ZONES RANGE FROM 32-36F. A FEW LOCATIONS IN
ZONE 3 WILL FALL BELOW FREEZING...PERHAPS INTO THE UPPER
20S...BUT NOT WIDESPREAD ENOUGH FOR A FREEZE WARNING. WE ALSO
CONSIDERED A FROST ADVISORY FOR ZONES 2 AND 76...BUT MID CLOUDS
HAVE BEEN SLOWER ERODE IN THOSE ZONES (SOME LIGHT PRECIP WAS
PERSISTING UNTIL THE LAST HOUR IN A COUPLE LOCATIONS) AND
TEMPERATURES IN MOST AREAS WILL ONLY DROP TO 36-38F.

PATCHY FOG HAS ALSO DEVELOPED IN VALLEY LOCATIONS EARLY THIS
MORNING BUT SHOULD BEGIN TO GRADUALLY DISSIPATE BY MID MORNING. A
MOSTLY SUNNY TO PARTLY CLOUDY SKY CAN BE EXPECTED THIS
AFTERNOON...ALTHOUGH TEMPERATURES WILL REMAIN A BIT BELOW NORMAL.

THE NEXT COLD FRONT APPROACHES TONIGHT. LITTLE IF ANY
PRECIPITATION CAN BE EXPECTED EARLY THIS EVENING...BUT IT WILL
THEN QUICKLY OVERSPREAD AT LEAST THE NORTHERN HALF OF OUR AREA
AFTER MIDNIGHT WITH ROBUST WARM AIR ADVECTION AND ISENTROPIC
LIFT. SNOW LEVELS REMAIN A BIT TRICKY. OVERALL...THEY SHOULD
BEGIN TO RISE...BUT AM CONCERNED THAT COLD AIR MAY GET TRAPPED IN
SOME VALLEY LOCATIONS DESPITE PRONOUNCED SOUTHERLY FLOW IN
ADVANCE OF THE FRONT. A WINTER WEATHER ADVISORY MAY ULTIMATELY BE
NEEDED FOR ELEVATIONS ABOVE 3500-4000 FEET...BUT WILL ALLOW THE
NEXT SHIFT TO MORE CLOSELY EXAMINE THIS POSSIBILITY WITH THE FULL
SUITE OF 12Z MODEL DATA. THE H5 TROUGH LOOKS TO DE-AMPLIFY AS IT
MOVES INLAND...WHICH COULD ALLOW SNOW LEVELS TO RISE MORE
RAPIDLY. IN THE LOWER ELEVATIONS...THIS SYSTEM PROMISES TO BRING
THE NEXT WIDESPREAD RAINFALL...WITH TOTALS AVERAGING BETWEEN
0.5-1 INCH. LOCALLY HIGHER AMOUNTS ARE POSSIBLE IN FAVORED
TERRAIN...ESPECIALLY GIVEN STRONG UPPER JET SUPPORT AND ROBUST
THETA-E ADVECTION. FORTUNATELY...GIVEN THE FAST FLOW ALOFT...THE
FRONT WILL BE RATHER QUICK TO EXIT AND MUCH OF THE ORGANIZED AND
PERSISTENT PRECIPITATION WILL COME TO AN END FRIDAY EVENING.
MAINLY DRY WEATHER IS STILL EXPECTED ON SATURDAY...WITH JUST A
FEW SCATTERED SHOWERS.

A MORE POTENT SHORTWAVE TROUGH ARRIVES FOR SUNDAY INTO MONDAY.
THIS SYSTEM IS CONTINUING TO TREND A BIT COLDER AND
STRONGER...SIMILAR TO THOSE WE EXPERIENCED EARLIER THIS WEEK.
THERE CERTAINLY COULD BE CONVECTION AND HIGH ELEVATION SNOW
ISSUES...BUT DETAILS WILL NOT BECOME CLEAR FOR ANOTHER DAY OR SO.
BEYOND THAT...MODELS CONTINUE TO ADVERTISE A PATTERN CHANGE BY
THE MIDDLE OF NEXT WEEK WITH A RETURN TO DRIER AND WARMER
CONDITIONS AS RIDGING KEEPS SHORTWAVES FARTHER NORTH. BETTWY

&&

.AVIATION...VFR CONDITIONS PREVAIL OVER MOST OF THE AREA THIS
MORNING WITH THE EXCEPTION OF SOME INTERIOR VALLEYS...WHERE
IFR/LIFR CIGS HAVE DEVELOPED AND PERSISTED. ONCE LOW CIGS BURN
OFF THIS MORNING..VFR CONDITIONS WILL PREVAIL ALTHOUGH HIGH
CLOUDS WILL BE ON THE INCREASE AHEAD OF THE NEXT SYSTEM. RAIN AND
GUSTY WINDS WILL AFFECT TAF SITES AFTER MIDNIGHT. CLARK

&&

.MARINE...WINDS WILL INCREASE TO SCA LATE TONIGHT AND INTO FRI
MORNING WITH GALES LIKELY OVER Z475 LATE PERIOD 2/EARLY PERIOD 3
AND POSSIBLE GALE FORCE GUSTS OVER Z450 BEGINNING EARLY PERIOD 3.
MAINTAINED GOING TREND OF CUTTING BACK ON MODEL-PROGGED SWELL
HEIGHT BY AT LEAST A COUPLE FT AS THIS CONTINUED TO LOOK
REASONABLE. GUIDANCE IN GENERALLY GOOD AGREEMENT ON ANOTHER UPPER
TROF DIGGING INTO THE NW LATE THIS WEEKEND...WHILE SOME VARIATION
IN THE SFC CIRCULATION WILL BE NOTED AS MODELS GET BETTER HANDLE
ON UA ENERGY... GENERAL THEME IS TYPICAL OCCNL FROPA WITH ASSOC
HIGH WINDS/SEAS...THE FIRST LATE THURS/EARLY FRI AND THE NEXT ON
SUN. ALSO SIGNIFICANTLY UNDERCUT CURRENT ENP SOLUTION OF 25+FT NW
SWELL FOCUSED ON OUR COAST ON SUNDAY...SAFE TO ASSUME MSLP
PATTERN AND SUBSEQUENT SWELL WILL CHANGE OVER THE NEXT 100HR SO
MAINTAINED SUB-20FT SWELL FOR NOW. CLARK

.EKA WATCHES/WARNINGS/ADVISORIES...
SMALL CRAFT ADVISORY UNTIL 5 PM MONDAY PZZ450-455-470-475.
