By October, unseasonably high temperatures affected the Mid-South and central United States. In the Memphis area and DeSoto County, highs reached the low 90s, approximately 15 degrees above the seasonal average. These temperatures approached or threatened to exceed historical daily records. A cold front was forecasted to arrive by the end of the week to restore typical fall temperatures.
