Extended forecast models through at least August 18 indicate a strong ridge of high pressure that will remain over the Northwest for much of the time. We will get occasional weak troughs of low pressure (like today 8-8-2012) that move into the region for some minor cooling and chance of a few mountain showers. However most of the period we can expect warm and dry conditions. The 500 mb chart below (18,000 feet) confirms this ridge of high pressure over the Northwest which generally brings dry and sunny conditions.
