More than 3,500 temperature records have been shattered in the U.S. this past week, from June 30-July 6, 2012, according to NOAA. The tally of record high temperatures during the time period is 2,412, and the tally of maximum low temperature records is 1,169.
From July 1-July 6 alone, 1,916 record highs have fallen, while 1,034 maximum low temperature records have been broken. Besides challenging daily records, some cities may have record streaks of high temperatures that will go down in the record books.
St. Louis is located in the heart of the heat wave. The mercury has soared to 100 degrees or higher for ten days in a row in St. Louis through Saturday, making it will be the second longest streak of 100-degree Fahrenheit (37,77 degreee Celsius) temperatures since 1936.
Chicago’s temperature has climbed to 37,7 °C (100 degrees Fahrenheit or higher for 3 consecutive days as of Friday. This is the first time since August of 1947 that Chicago hit 37,77 °C (100 or higher) for 3 days in a row. This streak has since broken as temperatures cooled Saturday afternoon after reaching 36,66 °C (98 Fahrenheit).
Saturday became the 4th consecutive day of 100 degree plus high temperatures in Fort Wayne, Ind. This broke the old record of consecutive 100 degree days which was set in 1988.
Meanwhile, Washington, D.C., hit 35 °C (95 degrees Fahrenheit or higher) for the tenth consecutive day on Saturday, the longest streak ever recorded. With highs forecast to approach 100 degrees today, the streak should end up being 12.
