AVIATION...12/00Z TAFs

VFR conditions prevail across the region early this evening. Around 08Z, expect the return of IFR/LIFR conditions to the coast near Brookings, with MVFR and local IFR conditions also beginning to form and returning overnight north of Cape Blanco. MVFR is likely in the Umpqua Valley, including Roseburg around 12Z to 18Z on Saturday morning.

An incoming system on Saturday will bring lifting of existing ceilings, but also increasing VFR cloud cover across the area. Showers and isolated thunderstorms are expected north of Gold Beach Saturday afternoon, with light showers spreading inland across much of the area into Saturday night.

MARINE...Updated 800 PM PDT Friday, September 11, 2026

Winds will continue to ease overnight, with seas at a minimum on Saturday morning. Winds shift to the south Saturday ahead of a cold front that will pass onshore Saturday night. Steep seas are possible Sunday night into mid-week, especially south of Cape Blanco, as the thermal trough redevelops.

KEY MESSAGES...

* Cooler high temperatures today, significantly cooler Saturday/Sunday (15-20 degrees below normal), trending back to near/above normal by mid-week.

* Gusty winds/low RH this afternoon bring elevated fire weather concerns east of the Cascades.

* Showers/light precipitation expected on Saturday, highest precip amounts expected along the coast and north of Rogue-Umpqua Divide.

* 15-25% chance for thunderstorms over marine waters and along the coast.

* Wind gusts 25-35 mph expected east of Cascades/Shasta Valley on Saturday.

* Light showers linger along coast/NW sections Sunday morning, trending drier through the day. Dry conditions continue through next week.

DISCUSSION...A broad upper level trough will linger over the region today, resulting in temperature trending cooler today with highs in the mid 70s to mid 80s for most inland valleys. Gusty winds and dry daytime humidities are expected this afternoon and evening for areas east of the Cascades, resulting in elevated fire weather conditions. Conditions aren't quite expected to reach critical values today, and even if they were, recent moisture has greatly lowered fire weather concerns for the time being.

A stronger low drops over the area on Saturday, bringing a much more significant cooldown for the weekend and stronger winds to the region. The mid-level jet associated with this low peaks around 35 to 40 kts Saturday before pushing southeastward and strengthening a bit. This will limit any headlines for gusty winds, but expect widespread gusts of 25 to 35 mph to common east of the Cascades/northern California and the higher terrain. Some of the windiest spots could gust to 40 mph Saturday afternoon. Despite these winds, fire weather concerns will be mitigated by increasing daytime RHs on Saturday compared to today/Friday. Aside from gusty winds, Saturday will feel quite cool, especially compared to recent days. High temperatures will top out around 15-20 degrees below normal, feeling more on par with late October than mid September. Widespread showers will develop west of the Cascades on Saturday with some scattered activity across the East Side as well but primarily north of Highway 140. Precipitation chances remain highest along/west of the Cascades and north of the OR/CA border and amounts are generally expected to be in the 0.10"-0.25" for the coast and north of the Rogue/Umpqua Divide, with a few hundreths for the rest of the area southward to the state border. Instability with this trough will bring a chance (15-25%) for thunderstorms on Saturday, mainly over the coastal waters and along the coast.

This low shifts east of the area on Sunday and conditions will trend drier. There could be some showers that linger through the morning across far northern areas and the coast, but most areas will see a dry day on Sunday. Well below normal temperatures will continue through Sunday, and we'll need to monitor the potential for frost/freeze products for portions of the East Side Sunday morning and again, Monday morning. Lingering cloud cover may limit areas of frost/freeze on Sunday morning. Then, with clearing skies Sunday night and continued cold air in place, chances for frost and freeze increase for valleys east of the Cascades. Temperatures trend warmer on Monday onward, though remain below normal through around midweek. /BR-y
