Thatâs how the National Weather Service described the historic heat wave hitting the Pacific Northwest, pushing daytime temperatures into the triple digits, disrupting Olympic qualifying events and breaking all-time high temperature records in places unaccustomed to such extreme heat. Portland, Oregon, reached 112 degrees Fahrenheit (44.4 Celsius) Sunday, breaking the all-time temperature record of 108 F (42.2C), which was set just a day earlier.
