![]() “There is no context really, in the sense that there is no analog in our past for what we are likely to see this week,” says Dr. Turns out, the models were correct and we should expect extreme heat waves, even unprecedented ones like this to become more routine. Were the models wrong? Or, given climate change, should we now expect the unexpected - is this now just becoming routine? And while the heat will break along the coast of Washington and Oregon by midweek, the record heat will continue over inland Washington, Oregon, Idaho and Montana through late week.įor the past week, as computer models have consistently forecast seemingly unbelievable numbers, meteorologists struggled to grasp how a heat wave of this magnitude could even be possible, given this region has never experienced anything of this magnitude before. Some of the inland cities in eastern Washington and Oregon will likely max out in the 115-120 degree range. Remarkably, in this one heat wave, highs in the city will easily top 100 degrees 3 days in a row. In its history, Seattle has only reached 100 degrees three times. On Sunday the thermometer is expected to reach a staggering 112 degrees - that’s 5 degrees higher than the all-time record of 107 degrees, prior to Saturday’s 108.Īfter a record high of 102 on Saturday, the thermometer is likely to shatter it’s all-time record high of 103 degrees in Seattle on Monday, with a forecast high of 108. helps explain how we know this is so historic #WAwx #ORwx #MNwx /nC2mGtRUwm- Mike Augustyniak June 27, 2021Īs the heat dome continues to build, cities like Portland will likely break their all-time heat record again, on back-to-back days. ![]() It's never been hotter in Portland than it was yesterday all part of an ongoing, historic, and dangerous heatwave in the NW many homes don't have A/C. The back to back and dueling heat waves are made more likely by a very wavy jet stream and our unnaturally heating climate. is also seeing the heat ratchet up, with feels like temperatures pushing 100 degrees by Monday and Tuesday in the major cities of the I-95 corridor. Intermountain West, Desert Southwest and California with hundreds of record highs. This heat wave comes on the heels of another historic heat wave less than two weeks ago that baked the U.S. The heat is being caused by a combination of a significant atmospheric blocking pattern on top of a human-caused climate changed world where baseline temperatures are already a couple to a few degrees higher than nature intended. ![]() These are extremely dangerous numbers, especially in a region not used to heat like this, where many people do not have air conditioning.īy Monday, some - if not all - of the all-time record highs seen below are forecast to break, with many more cities not listed here expected to achieve the same feat. ![]() Canada is expected to register the nation’s all-time highest temperature before the event is done. Portland, Oregon, has already broken its all-time record hottest temperature at 108 degrees on Saturday and the peak of the heat wave has not even been reached yet. By one measure it is more rare than a once in a 1,000 year event - which means that if you could live in this particular spot for 1,000 years, you’d likely only experience a heat dome like this once, if ever. Pacific Northwest and British Columbia, Canada, is of an intensity never recorded by modern humans.
