Fresh on the heels of a blast of unseasonably chilly summer weather last week, yet another shot of cool air has spread across parts of the central and eastern United States. Several record lows have already been set, and even parts of the South are seeing relief from the summertime humidity.
The cool air first spread throughout the Plains and Midwest on Sunday, dropping high temperatures 10 to 20 degrees below average from the Texas Panhandle and central Oklahoma to the Dakotas and Minnesota.
On Sunday morning, Casper, Wyoming, recorded its coldest August temperature on record with a low of 29 degrees. The old August record low was 33 degrees in 1977. Weather records in Casper date back to 1939.
Rapid City tied its coldest record low for August on Sunday morning and set a new daily record when the temperature dropped to 38 degrees.
And on and on. Record cold after record cold.
