DISCUSSION

Updated aviation discussion.

AVIATION...08/18Z TAFs

Marine stratus has eroded (yielding VFR) at all coastal areas except from around Pistol River southward. This area of stubborn IFR low clouds should also erode this afternoon as offshore NE winds take hold. VFR will prevail inland across the remainder of the area, except areas of wildfire smoke and haze will cause local visibility reductions, especially in the immediate vicinity and just downwind of the fires. Klamath Falls reported visibility as low as 2 sm this morning, but web cams and satellite imagery indicate improving visbility recently. We expect breezy northwest winds this afternoon/evening at most TAF sites, generally 20-25 kt, except up to around 30 kt at North Bend. Areas of IFR/LIFR marine stratus will return to the coast, especially north of Cape Blanco overnight into Sunday morning. -Spilde

MARINE...Updated 730 AM PDT Saturday, August 8, 2026

North winds will continue to strengthen this weekend into early next week. Steep seas are expected south of Cape Blanco through this morning. Then, gale force winds and very steep seas are expected to develop south of Port Orford this afternoon through Monday while gusty north winds and steep seas expand north of Cape Blanco. These conditions could persist through middle of next week. -Spilde

KEY MESSAGES...

* Hot, dry, and breezy/windy conditions are the overall theme going forward resulting in elevated fire weather conditions through this weekend

* Cooler and more widepsread seasonable temperatures start Monday but areas of triple digit highs remain over western Siskiyou County through next week

* Areas of smoke remain possible due to nearby wildfires which could bring unhealthy air quality

* Early signs pointing at thunderstorm chances increasing as early as Friday but more likely on Saturday

DISCUSSION (Today through Friday)...

The overall pattern for the next several days will be noted by high pressure over the Four Corners Region, resulting in a general southwest to zonal flow at 500mb over the forecast area. This pattern will continue to bring hot, dry, and breezy/windy conditions through the weekend with more seasonable temperatures by Monday for most areas. There are very subtle pieces of energy aloft embedded in this flow that may lead to an uptick in wind speeds under the very dry airmass in place through early/middle next week. This will result in at least elevated fire weather conditions the next several days. Isolated areas of critical fire weather conditions are also possible, but may lack the required length in time each day. Nevertheless, increased fire weather concerns exist through the weekend with improving conditions expected next week.

By next week (Thurs/Fri), we may see a pattern change, and there is some evidence of a cutoff low forming off the California coast that could slide north through the PacNW. This could bring increased chances for thunderstorm activity as early as Friday but more likely on Saturday. At this time details are somewhat unclear, but chances will exist for most of the forecast area. This could lead to increase fire danger from lightning starts. Will continue to monitor the situation going forward.

Lastly, smoke will be the other factor as the diurnal wind pattern continues to spread areas of smoke across the forecast area. Smoke is very difficult to forecast with uncertainties involved in fire activity/suppression and exactly how much smoke will be introduced into the atmosphere. That said, expect areas of smoke until an airmass change occurs.
