2007 North America South and Eastern heatwave


The 2007 North America South and Eastern heatwave was a continuation and eastward expansion of the 2007 Western North American heat wave which began in late June 2007. The heatwave expanded eastward starting at the very end of July and lasting into the first weeks of August. This heat wave was notable for both associated severe drought over a large swath of the southeastern United States, and parts of the Great Lakes region, and its late season ending, with temperatures continuing, although more sporadically, well into the 90s °F (30s °C) into September and October in the mid-Atlantic region.

The North American South and Eastern Heatwave was responsible for oppressive heat and building drought across the central and southern Midwest and into the southeast. Temperatures were soaring above 100 °F (38 °C)s as far north as Kansas City, MO and St. Louis, MO. At Raleigh-Durham, North Carolina, on August 9 and 10, the temperature reached 104 °F (40 °C). Much of the east coast experienced highs topping out around the century mark like at Charleston, SC and New York City, NY. Dew points reached the mid 70s °F (24 °C), creating a Heat Index values of 108 °F (42 °C) or more in much of the affected areas. For that reason, nearly two dozen states were in eitherHeat Advisories, or Excessive Heat Warnings or Watches, with the area of most watch or warning coverage in the Mississippi River Valley region from Illinois and Missouri down to Louisiana and the Southeast Atlantic Coast, as well as parts of the Mid-Atlantic.
