CHEYENNE, Wyo. — As part of a sweltering heat wave in southeastern Wyoming, Cheyenne’s high temperature Monday reached the highest value ever recorded for Monday’s date, July 18.
The National Weather Service in Cheyenne reported at 1:57 p.m. Monday that the city’s temperature clocked in at 98 degrees, setting a new all-time high temperature record for July 18. The value breaks Cheyenne’s previous record for that day of 97 degrees, set in 1998.
The number is two degrees shy of Cheyenne’s overall temperature record of 100 degrees, last reached in June 1954. Wyoming’s capital city has never officially reached a high temperature over 100 degrees.
Both a heat advisory and a fire weather watch are currently in effect for Cheyenne, with the watch scheduled to end at 8 p.m. and the advisory scheduled to end at 9 p.m. Other parts of southeastern Wyoming and the Nebraska Panhandle are under various other weather alerts, such as excessive heat warnings and red flag warnings.
Even with the scorching heat, Cheyenne could see some isolated thunderstorms pop up as Monday evening turns to night. A 20% chance of precipitation is in the city’s forecast from 9 p.m. to midnight as Monday night’s low temperature is currently expected to dip to 66 degrees.
