Another upper level low (Shaded “U” shape with blue arrows) is moving in starting a cooling trend in the Pacific Northwest. A frontal system is pushing in from the west and along with the upper level low they combine to send moisture at us from the south and southwest. Another frontal system looks like it will move through Oregon next Tuesday. Autumn officially begins with the Autumnal Equinox at 7:29 PM next Monday September 22nd.
