An upper level high pressure ridge (Shaded “Arch” shape with blue arrows) is getting stronger and moving over us for a rather rapid warmup to what could reach record high temperatures. By Monday we’ll have a frontal system poised offshore moving our way bringing the chance of showers and thunderstorms out ahead of and long it. By early Wednesday the frontal system moves onshore bringing showers with it. As you can see a frontal system hangs offshore on its way to the Pacific Coast next Friday.

An upper level high pressure ridge (Shaded “Arch” shape with blue arrows) will slowly weaken, tilt to the northwest and move eastward allowing an upper level low (Shaded “U” shape with blue arrows) to move toward the Pacific Northwest. A surface frontal system is on its way to us now. A frontal system will be located offshore on Wednesday morning ready to move in. Another frontal system heads our way Friday. By next weekend we’ll have yet another frontal system bearing down on us.
