DISCUSSION

Key Points:

* Minor to Moderate impacts expected through this forecast

* The heat this weekend into early next week will bring Moderate impacts to the area as temperatures will be about 15-20 degrees above normal - Many westside areas could see highs around 100 degrees

* Frost potential for some eastside areas Thursday morning

* Monitoring fire weather conditions through the heatwave - Will see at least elevated fire weather concerns - Fuels forecast to become receptive for most of the area

Further Details:

An area of 500mb high pressure over the Pacific located between 130W/140W and 30N/40N will remain in place over the next few days, resulting in a dry northwesterly flow over the forecast area with no signals for precipitation. By this weekend, this center is closer to 130W and 40N and subsequently resulting in higher heights over the forecast area. By Saturday, temperatures are going to nudge closer to about 15 degrees above normal with Sunday and Monday both closer to about 20 degrees above normal. Many westside valleys will be close to 100 degrees on Sunday/Monday and potentially Tuesday.

Fire weather will need closer monitoring once the heat wave begins and fuels start to trend higher towards the 90th percentile and in some cases potentially the 97th percentile. At this time, wind conditions may be the one variable that keeps conditions tamed, but wind speeds will start to increase Saturday. This may result in at least elevated fire weather conditions this weekend and more likely next week.

Of note, but beyond this forecast period, there is the potential for the forecast to remain dry into later parts of this month.

AVIATION...10/18Z TAFs

VFR conditions prevail across the region with some lingering scattered-broken low end VFR stratus north of Cape Blanco and in the Umpqua Basin. VFR will prevail through the TAF period for most locations, with gusty north to northwest breezes this afternoon and evening. Winds will be strongest along the coast where gusts of 20 to 30 kt are expected. Skies will likely remain clear overnight, though some patchy IFR/LIFR could develop in the deeper portions of the Coquille and Umpqua Basins late tonight. All area terminals should remain VFR. /BR-y

MARINE...Updated 200 PM PDT Wednesday, June 10, 2026

A strengthening thermal trough will bring gusty north winds and steep to locally very steep wind driven seas south of Cape Blanco this afternoon and evening. The gusty north winds and steep seas are expected to spread north of Cape Blanco by Thursday morning and last through the weekend, while gales and very steep seas develop south of Port Orford. Winds and seas should ease somewhat next week, but probably at least remain hazardous to small craft.
