An upper air trough of low pressure (“U” shape) has away from Oregon. Weak high pressure will bring back the sun, but it won’t last very long. Another frontal system 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. There will be sun breaks between the showers.

Advisories: NONE AT THIS TIME.
