AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
408 AM PDT MON JUL 29 2013

.SYNOPSIS...AREAS OF SMOKE WILL PERSIST THROUGH MONDAY AS PREVAILING
FLOW CONTINUES TO TRANSPORT SMOKE FROM WILDFIRES IN SW OREGON
ACROSS NW CALIFORNIA. AN APPROACHING UPPER LEVEL TROUGH WILL PROVIDE
A COOLING TREND ACROSS THE INTERIOR WITH MORE PERSISTENT COASTAL
CLOUDS AS THE MARINE LAYER DEEPENS THROUGH MID WEEK.

&&

.DISCUSSION...AS OF 10Z...SATELLITE IMAGERY SHOWED LOW CLOUDS ALONG
THE MENDOCINO COAST AND IN AND AROUND THE HUMBOLDT BAY/EEL RIVER
VALLEY REGION. STRATUS WAS GRADUALLY MOVING NORTH ALONG THE
REDWOOD COAST...AND INTO THE RUSSIAN RIVER VALLEY APPROACHING UKIAH
FROM THE SOUTH. AREAS OF SMOKE LOOK TO PERSIST ACROSS NORTHWEST
CALIFORNIA AT LEAST THROUGH MONDAY...AS PREVAILING FLOW TRANSPORTS
SMOKE FROM WILDFIRES LOCATED IN SOUTHWEST OREGON. VISIBILITIES
DOWN TO 5 MILES WERE OBSERVED AT KCEC AND KACV ON SUNDAY DUE TO
THE SMOKE AND HAZE AND EXPECT MONDAY WILL BE SIMILAR. AN UPPER
LEVEL TROUGH APPROACHING THE WEST COAST SHOULD PROVIDE ENOUGH LOW
LEVEL MIXING TO HELP IMPROVE THE SMOKEY CONDITIONS BY TUESDAY.
SUBSEQUENTLY...THE APPROACHING UPPER LEVEL TROUGH WILL ALSO DEEPEN
THE MARINE LAYER CAUSING COASTAL CLOUDS TO PENETRATE FURTHER
INLAND AND TO BECOME MORE PERSISTENT...WITH COASTAL AREAS SEEING
LESS CLEARING DURING THE AFTERNOONS THIS WEEK. MODELS CONTINUE TO
HINT AT SOME DRIZZLE ALONG THE COAST THROUGH WEDNESDAY DUE TO
FORCING ASSOCIATED WITH THE UPPER LEVEL TROUGH...AND HAVE LEFT THE
POPS ALONG THE COAST GENERALLY THE SAME.

AS THE UPPER LEVEL TROUGH MOVES INLAND...MODELS INDICATE ENOUGH
INSTABILITY ON THURSDAY AFTERNOON OVER THE SISKIYOU MOUNTAINS THAT
A SLIGHT CHANCE OF THUNDERSTORMS WAS ADDED. OTHERWISE...FAIR
CONDITIONS ARE EXPECTED ACROSS THE INTERIOR THROUGH THE WEEK.
TEMPERATURES WILL BE ON THE COOL SIDE ACROSS THE INTERIOR FOR THIS
TIME OF YEAR THROUGH MID WEEK WITH THE UPPER LEVEL TROUGH
APPROACHING AND SETTLING OVER THE WEST COAST. TEMPERATURES THEN LOOK
TO WARM SLIGHTLY THROUGH THE END OF THE WEEK. STP

&&

.AVIATION...MARINE STRATUS HAS DEVELOPED ALONG THE COAST AGAIN
TONIGHT. BASES CONTINUE TO BE JUST UNDER 1000 FEET. THIS WILL LEAD
TO A BURNOFF VERY CLOSE TO THE SAME TIME AS SUNDAY. WE HAVE ALSO
BEEN SEEING A SMOKE LAYER AROUND 4K FEET OVER KCEC AND SOUTH ALONG
THE COAST FROM THE FIRES OVER SOUTHWEST OREGON. SOME PATCHY FOG WILL
ALSO DEVELOP IN FOG PRONE AREAS ALONG THE COAST. EXPECT THE IFR
CONDITIONS AT THE COASTAL SIGHTS TO HOLD ON TO EARLY AFTERNOON
BEFORE BREAKING UP. INLAND AIRFIELDS SHALL REMAIN GENERALLY CLEAR
WITH THE EXCEPTION OF KUKI WHICH WILL LIKELY SEE SOME MARINE AIR AND
ASSOCIATED FOG AND STRATUS BRINGING IFR CONDITIONS EARLY THIS
MORNING. MKN

&&

.MARINE...SEAS WERE STILL RUNNING HIGH AND AT OR ABOVE ADVISORY
CRITERIA EARLY THIS MORNING. GOOD NEWS IS THAT THE STRONG NLY
WINDS AND LARGE SHORT PERIOD SEAS WILL SUBSIDE TODAY. IT WILL
STILL BE BORDERLINE FOR AN ADVISORY EITHER FOR WINDS AND/OR SEAS
AFTER 9AM. IT GETS EVEN BETTER ON TUE...WITH NLY WINDS AND SEAS
SUBSIDING MUCH MORE SUBSTANTIALLY AS HIGH PRESSURE OVER THE NE PAC
WEAKENS AND THERMAL LOW PRESSURE OVER THE INTERIOR SHIFTS EASTWARD.
FOR THE REMAINDER OF THE FORECAST...NUMERICAL MODELS WERE IN GOOD
AGREEMENT WITH MAINTAINING RELATIVELY LIGHT WINDS THROUGHOUT MOST
OF THE FORECAST AREA THROUGH FRI. SEAS LOOK TO REMAIN RELATIVELY LOW
BUT WILL PROBABLY BE ROUGH AND SHORT PERIOD DOMINANT.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
     SMALL CRAFT ADVISORY UNTIL 9 AM PDT THIS MORNING PZZ450-455.

     GALE WARNING UNTIL 9 AM PDT THIS MORNING PZZ470-475.
