The first week of August is generally the hottest time of the year in Washington. This year, people in the Puget Sound region already have experienced some record temperatures, with highs topping 90 degrees for the first time in 2020 on Monday. Olympia reached an eye-popping 98 degrees. Seattle made it to 94. But a cooling trend that will continue through Monday has started, says KNKX weather expert Cliff Mass.
