MARINE
Updated 800 PM Saturday, June 14, 2025
High pressure offshore and low pressure inland persist through the weekend. Seas will remain dominated by a mix of northerly wind wave and steep fresh swell through Sunday with conditions hazardous to small craft. The strongest winds and steepest seas are expected south of Gold Beach through tonight. Brief, locally very steep seas possible through late this evening beyond 5 nm from shore from Cape Sebastian south. Winds and seas weaken slightly on Sunday but seas will remain steep. A weak front early on Monday is likely to disrupt the pattern and bring improved conditions that could last into next Wednesday.

PREV DISCUSSION... /Issued 226 PM PDT Sat Jun 14 2025/

DISCUSSION...Satellite is showing clearer skies west of the Cascades with fair weather cumulus and cirrus east and in Northern California. This afternoon's temperatures will be near normal with highs in the 70s and 80s inland with 60s at the coast. Winds will be slightly breezy later this afternoon, around 10-15 mph from the northwest/west.

Father's Day will have quiet weather. Starting off, lows tonight will not be as cold as last night. Overall mornings will have 40s east, 50s west and mid-40s at the coast. This range of lows can be expected through early next week as well. Sunday afternoon's highs will be slightly warmer with more east side valleys seeing highs near 80 degrees. On the west side, the Rogue and Illinois Valley, along with valleys in western Siskiyou County will be the warmest in the mid-/upper 80s and low 90s.

On Monday a shortwave trough will move through. There will be a 3-6 degree cooldown for the afternoon. The shortwave is enough to bring a rain chance (15-20%) to more of Lake County and very far eastern Klamath County Monday afternoon. A marine push will bring the chance for light rain offshore and this chance continues closer to shore Tuesday night into Wednesday morning.

Long term: The real change in the forecast comes closer to next weekend as a larger trough swings southward. The newer data is leaning towards cooler temperatures Friday, anywhere from 5-15 degrees below normal! There are differences in the models as of right now. First, the GFS is favoring a deeper low with the low being positioned closer to our area. For the Euro, the positioning is closer to northern Oregon. In terms of rainfall, the deeper low in the GFS would mean more rainfall potential west of the Cascades.
The afternoon package includes increasing the PoPs to areas southward closer to Josephine County. This trough is also forecast to increase winds to 15-25 mph east of the Cascades and near the Shasta Valley. As this is a week out, we will continue looking at these scenarios through the week.
