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: Since we changed to Daylight Saving time 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.
