Chicagoans basked in rare November warmth Tuesday as the mercury soared to the mid- and upper 70s. The city's official high temperature of 75 degrees was the city's warmest November reading in nearly 29 years, since a similar reading on Nov. 3, 1987. Since 1871 the city has logged such a warm November reading on only 20 other days spanning 17 years. While the 70s won't last, mild weather is slated to continue through Election Day with daily high temperatures expected to top 60 degrees. The only rain in the cards is expected to fall Wednesday as a storm system traverses the central Midwest. Expected rainfall totals could be substantial, averaging nearly 0.70 inches, but some areas could get as much as 1.5 inches. The outlook for Election Day in Chicago projects mild and dry weather.
