Weather Northwest 7 to 10 days

Issued August 17.
The map below is the average position and heights of the 500 mb level (usually found at 18,000 to 19,000 feet). This is the average position from August 24 to August 30 and this is a typical summer pattern for the West. Dry and warm conditions as we have a strong ridge of high pressure that will build in from the south and west.
