DISCUSSION

An upper ridge will bring above seasonal temperatures to start the week. Daytime highs are forecast to be 5 to 10 degrees above normal across northern California and southern Oregon on Monday and Tuesday. This will put coastal cities in the mid to high 60s, while west side valleys look to be in the mid to high 80s. The Rogue, Illinois, and Klamath River valleys may see some low 90s on Tuesday afternoon. East of the Cascades, today's highs stay in the low to mid 70s before reaching the mid to high 70s on Tuesday.

A weak front looks to pass over the area on Wednesday, pushing the ridge to the east and bringing seasonal temperatures across the area. Current precipitation chances on Wednesday are fairly low (10- 30%) and limited to the coast and Cascades. Outside of those meager chances and some afternoon breezes, this weak front is expected to be overall unimpactful. Zonal flow behind the front looks to keep seasonal temperatures in the forecast through the end of the week.

A low pressure system approaches the Pacific Northwest late Friday, but long-term models are showing more agreement in low pressure splitting to the south. Broadly speaking, deterministic long-term imagery shows the low approaching too far to the north to bring any substantial precipitation, then drops to the south once its farther east. ECMWF meteograms show expectation of coastal showers, but chances for rain drop sharply over inland areas. GFS meteograms don't even give the coast much of a chance. Current guidance has temperatures through the weekend below or at seasonal levels. Overall, this feature also looks to be largely unimpactful. This could change depending on if and where the split occurs, so stay tunes to future forecasts. -TAD

AVIATION...01/06Z TAFs

Mainly VFR conditions will prevail through the TAF period with typical afternoon breezes. Isolated LIFR is possible in the Coquille Valley and southern Umpqua Basin (south of Roseburg). Otherwise, VFR is expected through the TAF period.

MARINE...Updated 1200 PM PDT Sunday, May 31, 2026

A thermal trough pattern will maintain gusty north winds and steep to very steep seas. Winds ease steadily today, but unsettled seas continue into tonight. Conditions improve on Tuesday and likely remain through Wednesday with a low west-northwest persistent swell. Steep wind-built seas may develop in southern waters to end the week.
