An upper level low pressure trough (the “U” shaped dip in the yellow jet stream line) is moving in behind the high pressure ridge (“Arch” shape) that heated us up. The trough combined with some cool Canadian air will return our temperatures back to the 80s. A weak cold front should drop down and push through the Pacific Northwest Wednesday keeping our temperatures pretty steady.
