AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
314 PM PDT FRI SEP 11 2015

.SYNOPSIS...A PATTERN CHANGE WILL DEVELOP THIS WEEKEND AS AN
APPROACHING UPPER TROUGH BREAKS DOWN THE RIDGE. THIS WILL BRING
SEASONAL TEMPERATURES BACK TO NORTHERN CALIFORNIA THROUGH EARLY NEXT
WEEK. THERE WILL BE A SLIGHT CHANCE FOR THUNDERSTORMS SATURDAY AND
SUNDAY AFTERNOONS WITH A SLIGHT CHANCE FOR RAIN ON MONDAY.

&&

.SHORT TERM (TODAY THROUGH MONDAY)...TEMPERATURES WILL SLOWLY FALL
TOWARDS SEASONAL VALUES THROUGH THE WEEKEND INTO EARLY NEXT WEEK AS
AN APPROACHING UPPER TROUGH HELPS BREAK DOWN THE RIDGE OF HIGH
PRESSURE. A SHORTWAVE EMBEDDED IN THE RIDGE WILL INCREASE MOISTURE
ACROSS NORTHERN CALIFORNIA AND BRING A SLIGHT CHANCE FOR
THUNDERSTORMS ON SATURDAY AND SUNDAY. THE BEST INSTABILITY LOOKS TO
BE OVER SISKIYOU AND AND NORTHERN TRINITY COUNTIES WHILE THE BEST
DYNAMICS ARE FARTHER SOUTH IN MENDOCINO COUNTY. INCREASING MOISTURE,
HOWEVER, MAY LIMIT DAYTIME HEATING AS CLOUDS INCREASE OVER THE
REGION WHICH WOULD INHIBIT CONVECTIVE DEVELOPMENT. AS CONFIDENCE
STILL REMAINS LOW WITH CONVECTIVE POSSIBILITIES THIS WEEKEND SLIGHT
CHANCES FOR THUNDERSTORMS WERE MAINTAINED SATURDAY AND SUNDAY FOR
INTERIOR MOUNTAINS.

TEMPERATURES SHOULD DROP MORE SIGNIFICANTLY ON MONDAY AS A MORE
POTENT WAVE DIVES OVER THE PACIFIC NORTHWEST BRINGING COOL AND DRY
AIR OVER THE REGION. A COLD FRONT WILL SLIDE ACROSS NORTHERN
CALIFORNIA LATE MONDAY BRINGING A SLIGHT CHANCE FOR RAIN MOSTLY FOR
DEL NORTE AND NORTHERN TRINITY COUNTIES. KML

.LONG TERM (TUESDAY THROUGH FRIDAY)...DRIER CONDITIONS AND SLIGHTLY
COOLER TEMPERATURES WILL PREVAIL ACROSS THE REGION ON TUESDAY IN THE
WAKE OF A WEAKENING COLD FRONT WHICH PASSES ACROSS THE AREA ON
MONDAY. HOWEVER ANOTHER COLD FRONT WILL APPROACH THE AREA WEDNESDAY
EVENING INTO THURSDAY. MODELS HAVE INCREASED THE CHANCES FOR
PRECIPITATION WEDNESDAY NIGHT AND THURSDAY. THE GREATER CHANCES WILL
BE ACROSS NORTHERN AREAS WEDNESDAY NIGHT AND THURSDAY. INCREASED
CLOUDINESS AND CHANCES FOR SHOWERS WILL RESULT IN MORE CLOUDINESS
AND SLIGHTLY COOLER TEMPERATURES WEDNESDAY AND THURSDAY. DRIER
CONDITIONS WILL PREVAIL ACROSS THE REGION FRIDAY WITH LESS
CLOUDINESS AND SLIGHTLY WARMER TEMPERATURES.&&

.AVIATION...MVFR CONDITIONS AND LIGHT WINDS WILL CONTINUE AT KCEC
THROUGH THE EARLY EVENING. THE LOWER CONDITIONS ARE DUE TO STRATUS
REDUCING CEILINGS AND PATCHY FOG REDUCING VISIBILITIES. VFR
CONDITIONS MAY BRIEFLY OCCUR LATE THIS AFTERNOON AT KCEC. VFR TO
MVFR CONDITIONS AND LIGHT WINDS WILL CONTINUE AT KACV THROUGH THE
LATE AFTERNOON. VFR TO MVFR CONDITIONS AND IFR CONDITIONS AT TIMES
WILL OCCUR AT KCEC AND KACV THIS EVENING AND OVERNIGHT WITH THE
LOWER CONDITIONS DUE TO STRATUS REDUCING CEILINGS AND PATCHY FOG
REDUCING VISIBILITIES. WINDS WILL BE LIGHT TO CALM OVERNIGHT AT KCEC
AND KACV. VFR CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS WILL
CONTINUE AT KUKI THROUGH SATURDAY.

&&

.MARINE...WINDS AND SEAS HAVE DIMINISHED. MODERATE WINDS AND SEAS
WILL CONTINUE THROUGH TONIGHT. NORTHERLY WINDS AND STEEP SHORT
PERIOD SEAS WILL INCREASE SATURDAY NIGHT AND SUNDAY AS AN OFFSHORE
HIGH PRESSURE SYSTEM STRENGTHENS. ELEVATED WINDS AND SEAS WILL
CONTINUE THROUGH EARLY NEXT WEEK. SMALL CRAFT ADVISORIES WILL BE IN
EFFECT ACROSS THE NORTHERN OUTER WATERS SATURDAY EVENING THROUGH
MONDAY EVENING DUE TO THE INCREASING WINDS AND STEEP SHORT PERIOD
SEAS AND MAY NEED TO BE EXTENDED FURTHER DUE TO PERSISTENT STEEP
SHORT PERIOD SEAS. SMALL CRAFT ADVISORIES WILL BE IN EFFECT ACROSS
THE SOUTHERN OUTER WATERS EARLY SUNDAY MORNING THROUGH TUESDAY
MORNING DUE TO THE INCREASING WINDS AND STEEP SHORT PERIOD SEAS AND
MAY ALSO NEED TO BE EXTENDED FURTHER DUE TO PERSISTENT STEEP SHORT
PERIOD SEAS. THE WINDS AND SEAS WILL INCREASE FROM THE OUTER WATERS
TO NEAR SHORE WATERS SATURDAY NIGHT AND SUNDAY. THE WINDS AND SEAS
WILL BE HIGHER ACROSS THE OUTER WATERS. SMALL CRAFT ADVISORIES MAY
BE NECESSARY ACROSS THE NEAR SHORE WATERS SUNDAY NIGHT AND MONDAY
DUE TO STEEP SHORT PERIOD SEAS.

&&

.FIRE WEATHER...DECREASING TEMPERATURES AND INCREASING MOISTURE WILL
BE THE TREND THROUGH EARLY NEXT WEEK AS AN APPROACHING TROUGH BREAKS
DOWN THE RIDGE OF HIGH PRESSURE. WE MAINTAINED THE SLIGHT CHANCE
FOR THUNDERSTORMS FOR INTERIOR MOUNTAINS ON SATURDAY AND SUNDAY.
CONFIDENCE REMAINS LOW AS THERE ARE STILL QUESTIONS ON HOW MUCH
CLOUD COVER THERE WILL BE. THIS MAY LIMIT THE HEATING NEEDED FOR
CONVECTION AND THUNDERSTORMS. GUSTY RIDGETOP WINDS WILL BE
POSSIBLE SATURDAY AFTERNOON AND EVENING AS THE SHORTWAVE
APPROACHES THE AREA WITH GUSTS POTENTIALLY REACHING 20 TO 25 MPH.

ON MONDAY COLD FRONT WILL SLIDE ACROSS CALIFORNIA BUT LOOKS TO BE
ON THE DRIER SIDE. WINDS MAY INCREASE SLIGHTLY WITH THE PASSING OF
THIS FRONT LATER MONDAY. THE BEST CHANCE FOR RAIN WILL LIKELY BE
IN OREGON BUT STILL MAINTAINED SLIGHT CHANCES FOR RAIN ACROSS THE
NORTHERN MOST EKA FIRE ZONES. LATE IN THE WEEK MODELS HAVE BACKED
OFF ON THE RAINFALL AMOUNTS...BUT IT STILL LOOKS LIKE SOME RAIN IS
POSSIBLE. KML/MKK

&&
