An Upper Level High Pressure Ridge (Shaded “Arch” shape formed by arrows) returns hot weather and the winds have returned the haze and smoke from Oregon wildfires. It seems the hazy smoke filled air kept today’s high temperature in Eugene well bellow what was expected. The graphics for days 3-7 show a frontal system moving through Oregon Thursday, then another front pushing through the Pacific Northwest next Sunday.
