An upper level high pressure ridge (Shaded “Arch” shaped area with blue arrows) is weakening and a low (Shaded “U” shape with blue arrows) will follow bring more clouds and cooling us down again today. Then the slight chance of rain returns on Wednesday. Look for a couple of frontal systems (position shown is Sunday) to be moving through the Pacific Northwest over the weekend. For those who are wondering, Daylight Saving Time officially ends and Standard Time returns at 2:00 am Sunday November 1st (Or at Bedtime Saturday October 31st, Halloween).
