An upper air trough of low pressure (“U” shape) is moving to the south away from Oregon. Weak high pressure will bring back the sun, but it won’t last very long. Another frontal system (position shown is for Thursday AM) will be upon us by the middle of the week along with an upper trough again and that means the break will only last until Wednesday afternoon.

Advisories: NONE AT THIS TIME.
