This is just a weather prediction, so it is subject to revision, but the National Weather Service is expecting an historic heatwave in the American West next week, probably peaking next weekend. Temperatures in Death Valley will approach 130 degrees F, and Las Vegas will top 115 degrees F, if predictions pan out. The heat wave may extend to the Canadian Border.
From Andrew Freedman at Climate Central:
The furnace-like heat is coming courtesy of a “stuck” weather pattern that is setting up across the U.S. and Canada. By early next week, the jet stream — a fast-moving river of air at airliner altitudes that is responsible for steering weather systems — will form the shape of a massive, slithering snake with what meteorologists refer to as a deep “ridge” across the Western states, and an equally deep trough seting up across the Central and Eastern states.
One study, published in the Proceedings of the American Academy of Sciences in 2012, found that the odds of extremely hot summers have significantly increased in tandem with global temperatures. Those odds, the study found, were about 1-in-300 during the 1951-1980 timeframe, but that had increased to nearly 1-in-10 by 1981-2010.
