A  ridge of high pressure continues to keep us dry for the time being.  A frontal system moved through the extreme northern part of the Pacific Northwest Tuesday, but fizzled out and the high pressure will strengthen to keep the rain away from us. Enough moisture was trapped in the south Willamette Valley to keep Eugene in clouds and as a result much cooler temperatures Wednesday than expected. Today we’ll see more sunshine and warmer temperatures. Yet another frontal system will hit the coast Saturday, but this time there will be a chance of getting wet Saturday through Monday. Remember, Daylight Saving Time officially ends and Standard Time returns at 2:00 am Sunday November 1st (Or at Bedtime Saturday October 31st, Halloween).
