A scorching heat wave that affected much of the eastern two-thirds of the nation, setting an astonishing number of temperature records, has ended across the Midwest and mid-Atlantic.

While the heat wave wave subsides across portions of the East, scorching heat shifts into the West.

Helping to break down the heat in the South will be a zone of drenching showers and thunderstorms from Texas to North Carolina and southern Virginia.

Meteorologist Bill Deger reports that at least 75 deaths were attributed to the intense heat.

More than 3,840 temperature records were shattered in the U.S. from July 1- 8, 2012, according to NOAA. The tally of record high temperatures during the time period is 2,476, and the tally of maximum low temperature records is 1,365.

Since the beginning of July, 142 all-time record highs have been set or tied across 19 states.

Some cities also went down in the record books challenging record streaks of brutal high temperatures.

St. Louis was located in the heart of the heat wave. The mercury soared to 100 degrees or higher for ten days in a row in St. Louis through Saturday, making it the second longest streak of 100-degree temperatures since 1936.

Chicago's temperature has climbed to 100 degrees or higher for 3 consecutive days Wednesday through Friday. This is the first time since August of 1947 that Chicago hit 100 or higher for 3 days in a row. This streak has since broken as temperatures cooled Saturday afternoon, reaching 98.

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 95 degrees or higher for the eleventh consecutive day on Sunday, the longest streak ever recorded. That streak will end tomorrow as cooler air slides in from the north.
