FNUS56 KEKA 092042 FWFEKA FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA NATIONAL WEATHER SERVICE Eureka CA 142 PM PDT Thu Jul 9 2026 .DISCUSSION...Clear, dry, and hot weather will continue for interior valleys this afternoon through Friday. A large ridge of high pressure building over the region will push temperatures up into the mid to upper 90s. At the same time, humidity levels during the day will drop quite low into the teens and 20s. This dry air will quickly dry out the brush and grass in the forests, which increases the fire danger. Winds will stay mostly light and follow normal daily patterns, blowing gently up the mountain slopes in the afternoon. The immediate coast will be protected from this heat by a cool, damp layer of ocean clouds and fog, which will allow for excellent humidity recovery overnight. Looking ahead to next week, we are tracking a stronger heatwave inland, along with a small chance of moisture moving up from the south that could bring a risk of lightning to the northeastern mountains.
