A weak ridge of high pressure will be building up again clearing things out. Another frontal system will be moving through the extreme northern part of the Pacific Northwest Tuesday, but it will fizzle out and the high pressure will strengthen to keep the rain away from us. Yet another frontal system will hit the coast Sunday, but this time there will be a chance of getting wet Saturday and Sunday AM. Remember, Daylight Saving Time officially ends and Standard Time returns at 2:00 am Sunday November 1st (Or at Bedtime Saturday October 31st, Halloween).
