The combination of gusty east winds and clear skies will result in very low humidity across the region. Along with a prolonged stretch of dry weather, we’ll see unseasonably high fire danger for the next several days. This pattern is the result of an entrenched high-pressure system to the east of the cascades and a thermal trough to the west. Humidity is at 17% at Hillsboro Airport right now on. Winds will diminish Wednesday but humidity will remain low. Another round of gusty east winds is expected later this week. Fire danger should remain high through the weekend.
