The July 1995 Chicago heat wave led to 739 heat-related deaths in Chicago over a period of five days. [1] Most of the victims of the heat wave were elderly poor residents of the city, who did not have air conditioning , or had air conditioning but could not afford to turn it on, and did not open windows or sleep outside for fear of crime.

The dew point temperature equals the air temperature when the air is saturated with water; in all other cases the dew point will be less than the air temperature. [ 6 ] : 129 In technical terms, the dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same ...

The Federal Aviation Administration issued a ground stop at Chicago’s Midway Airport for most of Sunday morning due to low visibility in the area, but it has since been lifted.
ASOS DTS-1 dew point sensor. In contrast, the dew point measurement is considerably more complex. The original dew point sensor deployed on ASOS systems utilized a chilled mirror that is cooled to the point where a fine film of condensation forms on the mirror's surface. The temperature of the mirror at this condition is equal to the dew point ...
Originally named Chicago Air Park, [8] Midway Airport was built on a 320-acre (130 ha) plot in 1923 with one cinder runway mainly for airmail flights. In 1926, the city leased the airport and named it Chicago Municipal Airport on December 12, 1927. [1] By 1928, the airport had twelve hangars and four runways, which were lit for night operations ...
