Update AVIATION Discussion

AVIATION...26/06Z TAFs

VFR conditions prevail across the region and will likely do so through the TAF period for most locations. Some low end VFR ceilings linger in portions of the Umpqua Basin and Cascade Foothills, but should gradually clear overnight as offshore flow develops. This offshore flow should maintain VFR conditions along the coast by keeping the marine layer from developing. High level cloud cover streaming overhead should limit low cloud/fog development for the most part. Still, with the recent rainfall and moist ground, there ought to be some local valley IFR/LIFR late tonight into early Saturday, most likely in the Coquille and Umpqua Basins.

PREV DISCUSSION

/Issued 442 PM PDT Fri Sep 25 2026/

KEY MESSAGES...

* Cloud cover continues west of the Cascades, with scattered showers over Coos and Douglas counties through the evening.

* Overnight lows reach near or just below freezing east of the Cascades, but overnight cloud cover will prevent lower temperatures.

* Seasonal weather and overall uneventful weather is expected through much of the week ahead.

DISCUSSION...Westerly flow aloft continues this afternoon, bringing cumulus clouds across the area. Post-frontal showers continue over Coos and Douglas counties, with isolated activity possible over adjacent counties. Precipitation chances dissipate into the evening. Overnight in the mid to low 30s are expected tonight, but evening cloud cover look to keep temperatures from getting much colder.

Cool air lingering over the area will keep daytime highs 5-10 degrees below seasonal norms over the weekend. For west side areas, this means highs in low to mid 70s while the east side will be in the mid to high 60s. Deterministic imagery shows an upper trough around a cutoff low passing over central California, which might bring just enough instability to allow a stray thunderstorm or two to develop along or east of the Cascades on Sunday afternoon. Chances of thunderstorm activity on Sunday afternoon is in the single digits over those areas.

The week ahead looks to be fairly uneventful. Zonal/northwest flow follows the upper trough will bring temperatures back up to seasonal norms through midweek. A weak front passing to the north may bring a few light showers to parts of Coos and Douglas counties, but accumulated rainfall is unlikely. There's some divergence in long- term models into next weekend, but the overall difference looks to be whether temperatures say seasonal or warm a little. Additional widespread precipitation looks to remain absent through the forecast period at this point. -TAD

MARINE...Updated 230 PM PDT Friday, September 25, 2026... Steep seas continue across area waters this afternoon. Winds are turning northerly as a thermal trough develops. Winds north of Cape Blanco will drop below advisory levels early Saturday morning, while gusty northerly winds support an ongoing advisory to the south. Gusty winds and steep seas spread north of Cape Blanco Saturday afternoon and continue through the day Sunday. Winds and seas look to ease on Monday. While westerly swell increases on Monday, this increase does not look to support ongoing unsettled seas. -TAD
