A high pressure ridge (Shaded “Arch” shape with blue arrows) has set up over the Gulf of Alaska in such a way as to send cool Canadian air our way. A thermal trough of low pressure (dashed line along the Oregon coast) will help keep our weather pattern stable. We’ll have chilly nights followed by pleasant days with sunshine and average temperatures through the weekend, Columbus Day and beyond.
