The 2006 North American heat wave spread throughout most of the United States and Canada beginning on July 15, 2006, killing at least 225 people. That day the temperature reached 117 °F in Pierre, South Dakota, with many places in South Dakota that hit well into the 120s. A 130 degree temperature was reported at a remote farm in South Dakota. The heat wave went through several distinct periods: ⁕From July 15 to July 22 very high temperatures spread across most all of the United States and Canada. On Monday, July 17, every state except Alaska, Minnesota, and North Dakota recorded temperatures of 90 °F or greater. North Dakota had recorded a temperature of 104 °F the previous day. ⁕From July 23 to July 29 the abnormal heat was concentrated in the West coast and South West deserts. 164 fatalities were reported in California during this period. ⁕From July 29 to August 4 the heat wave moved eastward, causing further fatalities as it progressed. ⁕From August 4 to August 27, high temperatures persisted in the South and Southeast United States. The heat wave finally ended with the progression of a cold front through the Southern Plains. In early reports from this heat wave, at least three died in Philadelphia, Arkansas, and Indiana. In Maryland, the state health officials reported that three people died of heat-related causes. Another heat related death was suspected in Chicago. Wikipedia [ - ]
