A high pressure ridge (Shaded “Arch” shape with blue arrows) is setting up over the Gulf of Alaska in such a way as to send cold Canadian air our way. We’ll have frosty nights followed by pleasant days with sunshine and average temperatures. The high will push a frontal system from northeast to southwest pushing the cooler air through the “back door”at us.
