DISCUSSION

An approaching weak front will help to bring more seasonal temperatures across northern California and southern Oregon today. Coastal areas will see daytime highs in the low 60s. Most west side valleys will be in the high 70s to low 80s, while the Umpqua Valley looks to stay in the low 70s. Areas east of the Cascades will generally be in the low to mid 70s.

Outside of cooling, this passing front looks to have minimal impact. Breezy winds are expected across most inland areas this afternoon and evening, but even the highest speeds are safely short of Advisory levels. Morning 10-20% precipitation chances will be limited to coastal areas, with those chances dissipating into the afternoon. Low amounts of instability will be present over northeastern Lake County this afternoon, supporting 5% chances for isolated thunderstorms. Colder air behind the front will bring chances for overnight lows east of the Cascades to reach Frost temperatures.

Zonal flow behind the front will keep seasonal temperatures in the forecast through the end of the week. Long-term guidance is showing more agreement for the upper pattern through the weekend. Current imagery shows that the trough will not split, with the low passing to the north of the area. Precipitation chances are minimal, with slight chances for light showers over Coos and Douglas counties on Saturday. Gusty winds are possible over higher terrain across the area, but forecast speeds remain below hazardous levels. Areas in northern Lake and Klamath counties may see overnight lows reach freezing levels on Saturday night into Sunday morning.

Behind the trough, seasonal warmth returns Sunday before model imagery diverges early next week. Meteograms for both ECMWF and GFS are leaning towards the presence of beneficial precipitation on Monday and/or Tuesday, but the details (timing and quantity) are coarse. -TAD

AVIATION...03/12Z TAFs

Marine stratus remains in place along the coast, keeping flight levels at IFR/LIFR levels early this morning. An approaching weak front will also bring some light showers to parts of the coast this morning, possibly bringing locally lower ceilings and visibilities. Rain showers dissipate into the afternoon, but lingering cloud cover looks to keep MVFR levels in place along the coast.

Inland areas will see VFR levels under high ceilings. The passing front will bring a period of gusty winds to east side areas. These gusts ease tonight into early Thursday morning. -TAD

MARINE...Updated 200 AM PDT Wednesday, June 3, 2026

A weak front is bringing light showers over the waters this morning, but with no significant impacts expected. With normal winds and swell, seas will stay below Advisory levels today.

Behind the front, northerly winds increase across area waters and are expected to build steep seas south on Gold Beach from Thursday morning into Friday morning. These winds ease as another system passes to the north on Saturday but may return on Sunday. -TAD
