An Upper Level High Pressure Ridge (Shaded “Arch” shape formed by arrows) has weakened and that kept the temperatures up. An upper level low (“U” shape formed by arrows) brings in cooler air, but high pressure quickly returns to warm us back up a bit. The graphics for days 3-7 show no frontal systems trying to move into Oregon until next Thursday.
