UPDATES WERE MADE TO ADD A SLIGHT CHANCE OF
THUNDERSTORMS TO EASTERN LAKE COUNTY THIS AFTERNOON, AND TO EXTEND
BY 24 HOURS THE PORTION OF THE SMALL CRAFT ADVISORY THAT IS IN
EFFECT SOUTH OF PORT ORFORD, NOW THROUGH FRIDAY EVENING.
THUNDERSTORM ACTIVITY IS TAPERING OFF, BUT LINGERS IN LAKE COUNTY
EARLY THIS MORNING WITH THE AID OF AN UPPER LEVEL TROUGH AND
EMBEDDED SHORTWAVE CURRENTLY TRACKING ACROSS THE AREA. AROUND 8
AM, ACTIVITY SHOULD SHIFT EAST OUT OF OUR AREA. BUT, WEAK
LINGERING INSTABILITY LOOKS TO BE JUST ENOUGH TO WARRANT THE
AFOREMENTIONED SLIGHT CHANCE OF THUNDERSTORMS NEAR HART MOUNTAIN
LATER TODAY. CUMULUS BUILDUPS ARE ALSO EXPECTED FOR CENTRAL AND
EASTERN SISKIYOU COUNTY LATE TODAY, BUT MOISTURE LOOKS TO BE A
BIT TOO SHALLOW TO SUPPORT THUNDERSTORMS.
OTHERWISE, WEATHER IMPACTS DURING THE NEXT WEEK LOOK TO BE MINOR.
OUR AREA WILL BE BETWEEN A PERSISTENT TROUGH IN THE GULF OF ALASKA
AND A RIDGE OFFSHORE OF MEXICO. THIS WILL ALLOW FOR SOME SLIGHT
VARIATIONS WITHIN A SEASONABLE WESTERLY FLOW ALOFT. NIGHT AND
MORNING LOW CLOUDS WILL BE COMMON FOR THE COAST AND COASTAL
VALLEYS WITH SEASONABLY COOL TEMPERATURES. MEANTIME, A STABLE AIR
MASS IS EXPECTED INLAND WITH TEMPERATURES AROUND 10 DEGREES COOLER
THAN THEY HAVE BEEN OVER THE PAST FEW DAYS. THIS WILL STILL BE
ABOVE NORMAL, WITH HIGHS GENERALLY A FEW TO SEVERAL DEGREES ABOVE
NORMAL, MAINLY IN THE 80S, EXCEPT IN THE 70S IN THE MOUNTAINS.
SEASONABLY BREEZY WEST TO NORTHWEST AFTERNOON WINDS WILL ALSO BE
COMMON. -DW
AVIATION...11/12Z TAFS
ALONG THE COAST AND INTO THE COASTAL
VALLEYS, IFR/MVFR WILL CONTINUE THROUGH THIS MORNING. CONDITIONS
WILL GRADUALLY CLEAR TO VFR IN THE EARLY AFTERNOON WEDNESDAY, EXCEPT
LINGERING AREAS OF MVFR ARE POSSIBLE NEAR AND NORTH OF NORTH BEND
(KOTH). IFR MARINE STRATUS WILL RETURN EARLY THIS EVENING THEN
PERSIST THROUGH THURSDAY MORNING. A BIT MORE EXTENSIVE, THOUGH STILL
BRIEF, CLEARING IS EXPECTED FOR THURSDAY AFTERNOON IN COMPARISON
WITH THIS AFTERNOON.
INLAND, CONDITIONS ARE MAINLY VFR. THUNDERSTORMS HAVE DIMINISHED IN
COVERAGE, BUT ISOLATED TO SCATTERED THUNDERSTORMS WILL CONTINUE
THROUGH AROUND 15Z THIS MORNING FOR LAKE AND NORTHEAST MODOC
COUNTIES. ERRATIC AND STRONG, GUSTY OUTFLOW WINDS ARE POSSIBLE NEAR
THUNDERSTORMS. ADDITIONALLY, A FEW THUNDERSTORMS MAY POP UP IN FAR
EASTERN LAKE COUNTY THIS AFTERNOON WITH CUMULUS BUILDUPS ALSO FOR
SOUTH CENTRAL AND EASTERN SISKIYOU COUNTY. -DW
MARINE...UPDATED 200 AM WEDNESDAY, JUNE 11, 2025
HIGH PRESSURE
OFFSHORE AND LOW PRESSURE INLAND ARE EXPECTED TO PERSIST INTO THE
WEEKEND. BREEZY NORTH WINDS WILL PERSIST THIS WEEK, HOVERING AT OR
JUST BELOW ADVISORY CRITERIA. THE STRONGEST WINDS AND STEEPEST SEAS
ARE EXPECTED SOUTH OF PORT ORFORD TO AROUND PISTOL RIVER AND OUT 30
NM FROM SHORE. SEAS WILL REMAIN DOMINATED BY A MIX OF NORTHERLY WIND
WAVE AND FRESH SWELL, WITH STEEP SEAS ACROSS ALL AREAS THROUGH
WEDNESDAY EVENING, THEN SOUTH OF PORT ORFORD AT LEAST THROUGH FRIDAY
EVENING AND POTENTIALLY THROUGH SATURDAY NIGHT. -BR-Y/DW
