On Friday, Death Valley National Park hit 55°C—130°F—on Friday and 54°C yesterday. Friday's temperature tied the record for the highest-known temperature on the planet:
As the third massive heat wave in three weeks kicked off in the West on Friday, Death Valley, Calif., soared to a searing 130 degrees. If confirmed, it would match the highest known temperature on the planet since at least 1931, which occurred less than a year ago.
Death Valley also hit 130 degrees last August, which at the time preliminarily ranked among the top three highest temperatures ever measured on the planet. It is still being reviewed by the World Meteorological Organization, which is the arbiter of international weather records.
The 130-degree reading observed Friday and last August only trail two other high temperatures ever measured on the planet: 1) The high of 134 set in Death Valley on July 10, 1913, and 2) a 131-degree reading from Kebili, Tunisia, set July 7, 1931.
But Christopher Burt, an expert on world weather extremes, questions the legitimacy of both of those measurements. He called the 1913 Death Valley reading “essentially not possible from a meteorological perspective” and wrote that the 1931 Tunisia reading has “serious credibility issues.”
In other words, the 130-degree readings from Death Valley on Friday and last year, if validated, may be the highest pair of reliably measured temperatures ever observed on Earth.
The National Weather Service forecasts today's high will hit 54°C again. By the time the heat wave finally breaks (sort of) on Tuesday, the weather station will have tied the record for the most consecutive days above 52°C (125°F):
The record for the number of consecutive days at 125 degrees or higher is 10, set in 1913 (June 28-July 5). This year, Death Valley hit 126 on July 7 and will likely continue that stretch of days with 125-plus temperatures through Tuesday. This would be eight straight days, which would be the second-longest streak in recorded history (tying eight days in 2013).
"An anomalously strong high pressure system overhead will remain overhead for multiple days," said Chelsea Peters, meteorologist at the National Weather Service in Las Vegas. "When the overnight low is warmer than the previous day's and similar temperature trends are expected, the daytime high would likely end up being just as hot, or hotter than the previous day."
Here in Chicago, we've got an England-like 20°C with very English rain, which could continue through Tuesday.
