Weather for the Northwest for early September

The extended forecast forecast models are in agreement as they bring a strong ridge of high pressure at the surface and aloft to the Northwest and the entire West Coast. The map below is for September 9 and this is the 500 mb map (at about 18,000 to 19,000 foot level) and you will notice a strong ridge of high pressure that covers the entire West Coast. This ridge brings warm and dry conditions for the Northwest. In fact some models suggest this warm and dry pattern continues through September 13.
