The hottest heat wave to ever hit the Pacific Northwest is continuing to scorch the typically cool region with triple-digit temperatures. Seattle is forecast to hit its all-time high of 104 degrees Sunday -- one day after breaking the record for hottest temperature in June at 101 degrees. The previous all-time high in Seattle was 101 degrees. Seattle has only recorded triple digits twice in history, Karin Bumbaco, the assistant state climatologist for Washington state, told ABC News. In Portland, temperatures reached 108 degrees on Saturday, breaking the all-time record of 107 degrees. The city is set to break its record again on Sunday with a forecast high of 112 degrees.
