A blocking Upper Level High Pressure Ridge (Shaded “arch” shape with arrows) continues to bring sunshine with mild daytime temperatures, but early next week an Upper Level Low Pressure Trough (Shaded “U” shape with arrows in same graphic) should bring some precipitation. The graphics for days 1-3 show a cold from offshore entering Washington Saturday morning. The graphics for days 3-7 increasing frontal activity increasing in the Pacific Northwest Tuesday through next Friday.
Note: The annual Orionid Meteor shower is in progress and peaks this weekend. For best viewing get away from the city lights and look up and to the northeast. The nearly full moon will make it more difficult to see the shower, so just before sunrise will be the best time because the moon will be setting.
