An Upper Level High Pressure Ridge (“Arch” shape) with a positive tilt to the East is moving Eastward which will allow frontal activity to bring us rain again. The graphics for days 1-3 show the front the moves into the Pacific Northwest today and tonight. The graphics for days 3-7 Wednesday through Sunday show the parade of frontal systems that will move over the Pacific Northwest through the period.
Note: The Authorities recommend that you test your Smoke Alarms, Carbon Monoxide Alarm, and your Radon Detector to make sure they are in good working order. If they aren’t working properly you need to replace the battery. If they are self contained, you’ll need to replace the alarm itself. Be safe.
