An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) is going to keep us in sunshine for a little while longer. The graphics for days 1-3 show the weak frontal system that fell apart Wednesday as it passed through Oregon and the next frontal system that moves through Friday. The graphics for days 3-7 show the some week surface disturbances (dashed lines) as the slide eastward and a frontal system that approaches and then moves through between Tuesday night and next Wednesday.
