An astonishing 4,313 record high temperatures were reached across the United States in July, according to the National Oceanic and Atmospheric Administration and the National Climatic Data Center. Two hundred ninety-nine of the record highs were the warmest temperatures ever observed for the entire month and an incredible 171 records were the all-time highest temperatures ever observed, according to Anthony Sagliani, Meteorologist for AccuWeather. Temperatures during the night were also among the highest ever observed, with a sweaty 3,545 record warmest nights during the month. The reason for the incredible heat has been the location of the jet stream, a thin river of air miles high that guides the path of potential storms. Unusually strong high pressure developed over much of the central part of the nation, an area where crops have been withering for months. This high pressure pushed the jet stream much farther north than usual, and there was virtually no chance of rain, Sagliani said. Additionally, since there was no rain and less moisture for the sun's energy to evaporate, most of the power went into heating the ground, and the result was weeks of searing heat. The first few days of August look to be no different across the nation's Heartland.
