AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
718 PM PDT SUN JUL 7 2013

.SYNOPSIS...EXPECT A TRANQUIL WEATHER PATTERN WITH SEASONAL
TEMPERATURES THIS WEEK. THE INTERIOR SHOULD BE MOSTLY CLEAR WHILE
THE COAST CAN EXPECT OVERNIGHT CLOUDS AND FOG WITH CLEARING EACH
AFTERNOON.

.UPDATE...DID A MINOR UPDATE TO THE FORECAST THIS EVENING TO
ADJUST CLOUD COVER SLIGHTLY ALONG THE REDWOOD COAST. CLOUDS HAVE
STARTED TO COME BACK INTO THE AREA A BIT QUICKER THAN EXPECTED.
OTHERWISE THE FORECAST LOOKS TO BE ON TRACK. MKK

&&

.PREV DISCUSSION... /ISSUED 309 PM PDT SUN JUL 7 2013/

SHORT TERM...QUIET WEATHER WILL PERSIST WITH NO SIGNIFICANT CHANGES
TO THE NEAR TERM FORECAST. COASTAL VALLEY FOG SCATTERED OUT ON TRACK
THIS MORNING WITH DAYTIME MIXING WHILE COASTAL STRATUS STUBBORNLY
STUCK TO THE COAST. COASTAL AIRFIELDS NORTH OF CAPE MENDOCINO ARE
BEGINNING TO SCATTER OUT JUST PRIOR TO 22Z. MUCH OF THE SAME FOR THE
NEXT FEW DAYS AS THE UPPER LEVEL TROUGH LIFTS AND HIGH PRESSURE
BUILDS IN FROM THE SW, MAKING IT MORE DIFFICULT FOR COASTAL STRATUS
TO SCATTER DUE TO A MORE COMPACT MARINE LAYER. AFTERNOON CLEARING ON
WEDNESDAY WILL BE MORE EFFICIENT WITH MIXING ASSOCIATED WITH AN
APPROACHING UPPER LEVEL TROUGH. OTHERWISE INTERIOR AREAS WILL BE
CLEAR WITH THE EXCEPTION OF CU DEVELOPMENT OVER THE MOUNTAINS. I
EXPECT A VERY WEAK WARMUP FOR INLAND AREAS SUNDAY THROUGH TUESDAY
WITH THE BUILDING OF THE RIDGE. OTHERWISE COASTAL HIGHS WERE BUMPED
DOWN CLOSER TO NORMAL DUE TO STRATUS LINGERING LATER IN THE DAY.
KML

LONG TERM...FOR THE MIDDLE AND LATER PORTIONS OF NEXT WEEK, A QUIET
WEATHER PATTERN WILL CONTINUE. UPPER LEVEL RIDGING CENTERED OVER THE
FOUR CORNERS REGION WILL GIVE WAY TO UPPER LEVEL TROUGHING DIGGING
INTO THE PACIFIC NORTHWEST. THERE MAY BE ENOUGH MID-LEVEL MOISTURE
AND INSTABILITY FOR ISOLATED THUNDERSTORMS OVER THE HIGHER INTERIOR
MTS THURSDAY AFTERNOON OR EVENING, BUT WITH SW FLOW ALOFT, ANY
CONVECTION THAT DOES DEVELOP WOULD QUICKLY MOVE EAST OF TRINITY OR
MENDOCINO COUNTY. WHILE MODELS ARE TRENDING TOWARD A SLIGHTLY MORE
AMPLIFIED TROUGH WITH BETTER RETURN FLOW, APPRECIABLE MOISTURE STILL
STAYS WELL SOUTH OF NORTHERN CALIFORNIA. OTHERWISE WITH THE TROUGH
ALOFT WILL BRING TEMPERATURE BACK DOWN TOWARD SEASONABLE LEVELS
UNTIL NEXT WEEKEND WHEN HEIGHTS BEGIN TO RISE AGAIN. THE LOW-LEVEL
FLOW AT THE COAST WILL GENERALLY BE NORTHERLY WITH AN ONSHORE
GRADIENT, SO EXPECT LOW CLOUDS AND FOG MOST DAYS. TROUGHING MOVING
THROUGH SHOULD AID AFTERNOON CLEARING THURSDAY AND FRIDAY.  AAD

AVIATION...NW CALIFORNIA REMAINED MOSTLY CLEAR TODAY WITH THE
EXCEPTION OF CU DEVELOPMENT OVER THE MOUNTAINS AND COASTAL STRATUS.
DISSIPATION OF VALLEY FOG WAS ON TRACK THIS MORNING WITH DAYTIME
HEATING/MIXING BUT THE COAST REMAINS STUBBORNLY INUNDATED WITH
STRATUS. KCEC AND KACV LOOK TO BE SCATTERING OUT AS OF 22Z AMONGST
OTHER AREAS NORTH OF CAPE MENDOCINO. AIRFIELD CONDITIONS SOUTH OF
CAPE MENDOCINO ARE LESS LIKELY TO IMPROVE AS LONG AS SOUTHERLY WINDS
WILL KEEP STRATUS TIGHT AGAINST THE COAST. ANY COASTAL SCATTERING
WILL BE BRIEF AS LIFR AND IFR CONDITIONS WILL RETURN TO THE COAST
THIS EVENING. AFTERNOON CLEARING TOMORROW WILL BE DIFFICULT, IF ANY
OCCURS AT, DUE TO BUILDING HIGH PRESSURE ALOFT COMPACTING THE MARINE
LAYER. OTHERWISE MOSTLY CLEAR FOR INLAND AREAS EXCEPT FOR CU
DEVELOPMENT OVER THE TRINITY ALPS AND YOLLA BOLLYS. KML

MARINE...18Z NCEP/OPC SURFACE ANALYSIS SHOWS THE EAST PACIFIC HIGH
DRIFTING OFF THE SOUTHWEST WHILE WEAKENING. AN UPPER TROUGH DIGGING
INTO THE PACIFIC NORTHWEST THIS EVENING WILL HELP TO FILL THE
THERMAL TROUGH ACROSS THE INTERIOR WEST. COMBINE, THESE FEATURES
WILL ALLOW THE PRESSURE GRADIENT OVER THE COASTAL WATERS TO WEAKEN.
WINDS AND SEAS WILL THEN COME DOWN AS A RESULT. FOR NOW, HAVE
ALLOWED THE SMALL CRAFT ADVISORY THROUGH THE SOUTHERN INNER WATERS
TO EXPIRE THIS MORNING AS WINDS AND SEAS HAVE FALLEN BELOW CRITERIA.
HOWEVER, SEAS DO REMAIN JUST BELOW SMALL CRAFT ADVISORY CRITERIA, SO
THEY MAY BE STEEP IN EXPOSED AREAS. EXTENDED THE GALE WARNING OVER
THE NORTHERN OUTER WATERS FOR MAINLY GALE GUSTS. AN 18Z ASCAT PASS
SHOWED A BROAD AREA OF 30+ KT WINDS IN THIS ZONE. LATE AFTERNOON AND
EARLY EVENING ARE TRADITIONALLY WHEN WINDS ARE HIGHEST IN THE SUMMER
MONTHS DUE TO DIURNALLY TIGHTENING OF THE PRESSURE GRADIENT. THIS IS
THE MAIN REASON FOR LEAVING THE GALE WARNING UP, TO CAPTURE THIS
EVENINGS PEAK WINDS. ONCE WE GET THROUGH MONDAY, WINDS AND SEAS ARE
EXPECTED TO COME DOWN SIGNIFICANTLY FROM THEIR PEAK LATE LAST WEEK.
RIGHT NOW, TUESDAY LOOKS LIKE THERE MAY BE A LULL IN THE WAVES
FOLLOWED BY A BRIEF PEAK ON WEDNESDAY THEN A MORE SUSTAINED LULL
THURSDAY INTO FRIDAY. THE TREND IS FOR LOWER WINDS AND LOWER SEAS
THROUGH THE WEEK. BFG
