We will start to have some changes starting this weekend, July 30 and July 31 as a weak trough of low pressure passes to our north to bring some cooling. In fact most forecast models bring troughs of low pressure in and out of the Pacific Northwest for the first week of August. With this pattern we can expect below normal temperatures during early August.
