7 to 10 weather forecast Cascades and Northwest

Map below is the average position of the 500 mb map (at about 18,000 foot level) for the June 12 to June 18 period. This map indicates a zonal pattern (westerly flow) into the Cascades and the rest of the Pacific Northwest. This type of pattern will generally bring average temperatures and close to average precipitation. However, lower confidence in this extended forecast as the models have been inconsistent lately.
