A blocking high pressure ridge (Shaded “Arch” shaped with blue arrows) has settled over the Pacific Northwest. Cold Canadian air has dried us out and given us the coldest temperatures of the season so far, particularly at night. Remember to be careful in the mountains due to the new snowfall and potentially icy driving conditions. A dying storm will be on its way to the Oregon coast Monday bringing back the chance of rain or snow by Monday afternoon followed by another stronger frontal system on Wednesday.
