NATIONAL WEATHER SERVICE EUREKA CA
1108 PM PDT WED JUN 11 2025
SYNOPSIS
INTERIOR DAYTIME HIGH TEMPERATURES FORECAST TO
DIMINISH EACH DAY THROUGH FRIDAY. COASTAL STRATUS COVERAGE
BECOMING LESS THROUGH THE WEEK WITH CLEAR SKIES POSSIBLE FRIDAY
AFTERNOON. BREEZY WINDS ARE TO BE EXPECTED THROUGH THE REST OF
THE WEEK INTO THE WEEKEND.
DISCUSSION
KEY MESSAGES:
* INTERIOR DAYTIME HIGH TEMPERATURES BECOME SUBJECTIVELY COMFORTABLE
THROUGH THE REST OF THE WEEK
* GUSTIER WESTERLY AND NORTHWESTERLY BREEZES IN THE INTERIOR VALLEYS
EACH AFTERNOON AND EVENING WEDNESDAY THROUGH SATURDAY.
* STRENGTHENING COASTAL NORTHERLIES MID TO LATE WEEK.
AN UPPER UPPER LEVEL TROUGH SWINGS OVER OUR AREA FROM THE NORTH
THROUGH THE REST OF THE WEEK. THIS SYNOPTIC WEATHER WILL BRING A
GENERAL COOLDOWN TO OUR TEMPERATURES THROUGH THE WEEKEND. THE
HIGHEST RECORDED INLAND VALLEYS CAPPED THEIR TEMPERATURES AT 94F IN
BIG BAR AND 93F IN NORTHEAST MENDOCINO. OTHER STATIONS FAILED TO
REACH 90F. THIS COOLING TREND WILL CONTINUE THURSDAY AND FRIDAY WITH
INALDN TEMPERATURES IN THE LOW 80S FRIDAY AFTERNOON. THESE COOLER
TEMPERATURES WILL ALSO BE ACCOMPANIED BY STRONGER WINDS WITH
AFTERNOON WIND GUSTS AROUND 15-20MPH IN THE LATER PORTION OF THE
WEEK.
THIS WEEK, AN UPPER LEVEL TROUGH WILL IMPACT THE PACNW WITH POSSIBLE
RAIN. WHILE MOST OF THE RAIN POTENTIAL LIES BE OUT OF OUR AREA AND
FOCUSED MOSTLY IN OREGAON AND WASHINGTON, THERE IS A LOW, <10%
CHANCE THAT DEL NORTE AND NORTHERN HUMBOLDT COULD RECIEVE SOME OVER
0.02" OF RAIN THROUGH MONDAY. WHILE THESE NUMBERS ARE NOT
ASTONISHING, THIS IS A NOTEABLE CHANGE IN WEATHER COMPARED TO OUR
TYPICAL SUMMER PATTERN.
AVIATION
AFTER BRIEF CLEARING EARL IN THE NIGHT, AND ELEVATED
MARINE LAYER HAS GENERALLY RETURNED ALONG SHORE ALONGSIDE MVFR
CEILINGS. THERE IS HIGH CONFIDENCE THAT CEILINGS WILL GRADUALLY
LOWER THROUGH THE NIGHT, WITH PERIODS OF IFR CONDITIONS (60% CHANCE)
EARLY THURSDAY MORNING. CLEARING IS EXPECTED TO BE BETTER THURSDAY
COMPARED TO WEDNESDAY WITH AN 80% CHANCE OF CEILINGS SCATTERING
ALONG SHORE LATE IN THE AFTERNOON. MVFR CEILINGS WILL MOST LIKELY
RETURN QUICKLY AFTER SUNSET THURSDAY. INTERIOR CONDITIONS WILL REMAIN
VFR WITH SLIGHT DIURNAL WIND ENHANCEMENT (GUSTS OVER 20 KTS) BEING
THE ONLY NOTABLE FEATURE. /JHW
MARINE
MODERATE TO STRONG NORTH WINDS HAVE PERSISTED IN THE OUTER
WATER OVERNIGHT, WINDS WILL CONTINUE TO CREEP UPWARDS AND CLOSER TO
SHORE INTO THE WEEKEND WITH NEAR GALE FORCE GUSTS THROUGHPUT THE
OUTER WATERS BY EARLY FRIDAY MORNING. THAT SAID, THE POTENTIAL FRO
PROPER GALE CONDITIONS ILL BE LOW (20% CHANCE). WINDS WILL BE
STRONGEST IN THE AFTERNOON AND WILL CALM SOMEWHAT AT NIGHT,
ESPECIALLY ALONG SHORE. STEEP SHORT PERIOD SEA UP TO 8 FEET WILL
GENERALLY DOMINATE THE SEA STATE. THOUGH WINDS WILL BE MORE MODERATE
CLOSER TO SHORE AND AT NIGHT, PERSISTENT STEEP SHORT PERIOD WAVES
WILL GENERALLY MAINTAIN AN ELEVATED SEA STATE. STRONG WINDS WILL
MOST LIKELY CONTINUE THROUGH THE WEEKEND AND ONLY SLIGHTLY EASE
EARLY NEXT WEEK. /JHW
