By the numbers: Virtually all of Oregon and Washington, plus portions of California, Idaho and Montana, are under excessive heat watches and warnings. This is the case even in downtown Portland and Seattle.
- Portland, Oregon, is forecast to reach low triple-digits on Saturday through at least Monday. The city is likely to break its June heat record, its record for most 100-degree days in June, and surpass its all-time high of 107°F, perhaps by a few degrees.
- In Seattle, where the average high temperature this time of year is in the low-to-mid 70s, the National Weather Service (NWS) predicts a high of 102°F on Sunday, which would break the record for the city's hottest temperature during the month of June.
- Seattle's all-time high temperature record is 103°F, and the city has only seen three 100-degree days in its history.
- Medford, Oregon and Spokane, Washington, are also predicted to shatter their all-time high temperature record by a few degrees.
- The heat will be most intense in inland areas of Washington and Oregon. There, temperatures are forecast to soar to between 100°F and 115°F on Saturday through Tuesday, and remain extremely hot through much of next week.
- Nearly every location along the I-5 corridor from Northern California to Washington is likely to set a monthly or even an all-time high temperature record during this event.
- Canada will also see extreme heat, and it's possible the country's all-time high temperature record of 113°F (45°C) will be equaled or eclipsed.
