AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
345 PM PDT TUE APR 28 2015

.SYNOPSIS...A WEAK FRONT MOVING OVER THE WEST COAST HAS BROUGHT
SOME SOME HIGH CLOUDS AND COOLER TEMPERATURES ACROSS THE AREA. A
FEW SPRINKLES ARE STILL POSSIBLE. DRY CONDITIONS WILL PERSIST THE
REST OF THIS WEEK. INTERIOR TEMPERATURES WILL TREND UPWARD
BEGINNING WEDNESDAY AS HIGH PRESSURE DOMINATES THE WEATHER
PATTERN THROUGH THE WEEKEND.

&&

.DISCUSSION...A WEAK FRONT IS MOVING ONSHORE THIS AFTERNOON
BRINGING SOME MID LEVEL CLOUDS TO THE AREA. SOME DRIZZLE HAS BEEN
REPORTED IN CRESCENT EARLIER THIS AFTERNOON...HOWEVER THIS HAS NOT
MADE IT AS FAR SOUTH AS EUREKA. SOME SPRINKLES ARE STILL POSSIBLE
OVER THE HILLS THIS EVENING...HOWEVER AMOUNTS WILL BE A FEW
HUNDREDTHS OR LESS. FARTHER INLAND THERE IS SOME CU BUILDING OVER
EASTERN TRINITY COUNTY...AGAIN SOME SPRINKLES ARE POSSIBLE.
TONIGHT THIS FRONT WILL MOVE INLAND AND SKIES WILL SLOWLY CLEAR
BEHIND THE FRONT AS OFFSHORE FLOW SETS UP. FROST IS POSSIBLE IN
SOME OF THE MOST PROTECTED INTERIOR VALLEYS...HOWEVER THE WINDS
SHOULD KEEP IT AWAY IN MOST AREAS.

WEDNESDAY CLEAR SKIES AND DRY CONDITIONS ARE EXPECTED ACROSS THE
AREA. HIGH TEMPERATURES INLAND WILL WARM SOMEWHAT OVER TODAY AS
HIGH PRESSURE BUILDS IN. GUSTY NORTH TO NORTHEAST WINDS ARE
EXPECTED ALONG THE COAST. GUSTS TO 30 MPH ARE POSSIBLE ALONG THE
COAST. GUSTY NORTHEAST WINDS WILL CONTINUE WEDNESDAY NIGHT INTO
THURSDAY MORNING...ESPECIALLY OVER THE RIDGES. THIS WILL KEEP RH
RECOVERIES POOR OVERNIGHT. THURSDAY HIGH PRESSURE WILL CONTINUE TO
STRENGTHEN. THIS WILL CAUSE TEMPERATURES TO INCREASE IN INLAND
AREAS AND WINDS TO INCREASE ALONG THE COAST.

FRIDAY INTO THE WEEKEND HIGH PRESSURE STARTS TO WEAKEN AS A
TROUGH SLIDES BY TO THE NORTH OF THE AREA. FOR NOW THIS TROUGH
LOOKS DRY...BUT WILL DIMINISH THE TEMPERATURES AND WINDS A BIT.
THIS MAY ALSO ALLOW SOME STRATUS TO MOVE UP THE COAST.

MONDAY INTO TUESDAY AN UPPER LEVEL LOW STARTS TO APPROACH THE
AREA. THIS MAY BRING SOME SHOWERS OR THUNDERSTORMS TO TRINITY
COUNTY. CONFIDENCE IS LOW...BUT 12Z MODEL RUNS SHOW SOME DECENT
INSTABILITY OVER THE HILLS OF TRINITY COUNTY SO HAVE ADDED A
SLIGHT CHANCE FOR THUNDERSTORMS. MKK

&&

.AVIATION...A WEAK COLD FRONT IS IN THE PROCESS OF PASSING
THROUGH NORTHERN CALIFORNIA THIS AFTERNOON. CEILINGS HAVE ALREADY
IMPROVED TO MVFR AT CEC FOLLOWING A PERIOD OF LIGHT RAIN...AND
WILL GRADUALLY IMPROVE TO VFR THROUGH THE EVENING. AT ACV...LOW
CLOUDS WILL LIKELY LINGER A BIT LONGER FOLLOWING A BRIEF PERIOD OF
LIGHT RAIN OR DRIZZLE LATE THIS AFTERNOON...BUT CEILINGS WILL
EVENTUALLY IMPROVE TO VFR DURING THE MORNING HOURS. VFR CONDITIONS
ARE EXPECTED AT UKI THE NEXT 24 HOURS. /BRC

&&

.MARINE...THE PRIMARY FORECAST CONCERN THROUGHOUT THE WATERS
CONTINUES TO BE THE TIMING AND STRENGTH OF INCREASING NORTHERLY
WINDS THIS AFTERNOON AS A WEAKENING COLD FRONT MOVES ONSHORE.
WINDS HAVE BEEN BEEN GENERALLY LIGHTER THAN ANTICIPATED AT
OFFSHORE BUOY SITES AHEAD OF THE FRONT...PARTICULARLY IN THE PAST
FEW HOURS...BUT ARE LIKELY TO QUICKLY INCREASE BEHIND THE BOUNDARY
AS IT PASSES THIS AFTERNOON. BY OVERNIGHT TONIGHT...SUSTAINED
NORTHERLY WINDS OF 20 TO 30 KT WITH GUSTS TO 35 KT ARE EXPECTED TO
DEVELOP SOUTH OF CAPE MENDOCINO...WITH SLIGHTLY LOWER WINDS
ELSEWHERE. THERE IS A BIT OF UNCERTAINTY REGARDING WHETHER OR NOT
GALE FORCE WINDS WILL SPREAD INTO A MAJORITY OF THE SOUTHERN INNER
WATERS...AND WHEN CONSIDERING THIS FACTOR ALONG WITH THE OVERALL
MARGINALITY OF THE WINDS...THE GALE WARNING FOR THIS EVENING WILL
REMAIN RESTRICTED TO THE SOUTHERN OUTER WATERS FOR THE TIME BEING.
THERE IS ALSO A CONCERN THAT BUILDING STEEP SEAS...WHICH MAY REACH
14 TO 16 FEET AT 10 TO 12 SECONDS IN THE SOUTHERN OUTER WATERS BY
LATE TOMORROW NIGHT...MAY PROPAGATE FAR ENOUGH INTO THE SOUTHERN
INNER WATERS TO MEET HAZARDOUS SEAS CRITERIA DURING THE DAY
TOMORROW. AGAIN...UNCERTAINTIES ABOUND HERE GIVEN THAT SEAS MAY
NOT BUILD TO THEIR FULL POTENTIAL BEFORE WINDS ACQUIRE A STRONGER
OFFSHORE COMPONENT OVERNIGHT WEDNESDAY...WHICH COULD LIKELY
PREVENT HAZARDOUS SEAS CRITERIA FROM BEING MET IN A MAJORITY OF
THE NEAR SHORE WATERS. AS SUCH...WILL CONTINUE TO MAINTAIN THE
CURRENT SMALL CRAFT ADVISORY FOR THE INNER WATERS FOR THE NEAR
TERM THROUGH THE REMAINDER OF THE WORK WEEK.

BY LATE WEDNESDAY...AS PREVIOUSLY MENTIONED WINDS WILL BEGIN TO TURN
A BIT MORE OFFSHORE...PULLING GALES FARTHER AWAY FROM THE NEAR SHORE
WATERS.  HOWEVER...STRONGER WINDS WILL LIKELY CONTINUE ACROSS THE
SOUTHERN OUTER WATERS THROUGH THE END OF THE WORK WEEK...AND WILL
LIKELY INCREASE ACROSS THE NORTHERN OUTER WATERS AS WELL.  WILL
CONTINUE TO MAINTAIN THE EXISTING GALE WATCH FROM TOMORROW AFTERNOON
THROUGH FRIDAY MORNING FOR THE NORTHERN OUTER WATERS...IN ADDITION
TO THE PREVIOUSLY DISCUSSED GALE WARNING FOR THE SOUTHERN OUTER
WATERS.  /BRC
