An upper level high pressure ridge (Shaded “Arch” shaped area with blue arrows) took over Saturday drying us out after some AM showers. Another low (Shaded “U” shape with blue arrows) will follow bring more clouds and cooling us down again by Tuesday. Then the chance of rain returns on Wednesday. Look for a couple of frontal systems to be approaching Oregon next Sunday. 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).
