This will be an active weather period as the region will be impacted by a large trough of low pressure off the coast with a cold front poised to move through this afternoon and evening. Current radar is showing a large swath of precipitation extending from the Wenatchee area eastward through the northern Columbia Basin and then southward toward the Blue Mountains. The cold front is expected to pass through the Cascades by mid-afternoon and shift to the Idaho Panhandle by early evening. We expect to see widespread precipitation develop along and ahead of the front. We will maintain our current flood watch through this evening over the northern third of our forecast area however we suspect that the main threat of flooding will be reserved for Okanogan and Chelan Counties. We have a 70% chance of rain throughout the day.

By Friday, the entire weather system passes to the east bringing just a chance of a morning shower with partly cloudy skies by afternoon. Sunday through the middle part of next week, a strong ridge of high pressure dominates our weather picture, which will allow for a drying and warming trend for our area. High temperatures by next Wednesday is expected to reach into the low 60’s.
