Cheyenne, Wyoming – Dangerous heat is expanding across eastern Wyoming and the Nebraska Panhandle, with temperatures climbing into the upper 90s and lower 100s through Monday. The prolonged stretch of hot weather, combined with unusually warm overnight temperatures, will increase the risk of heat-related illness for anyone spending extended time outdoors.
According to the National Weather Service in Cheyenne, a Heat Advisory remains in effect for Dawes County and northern Sioux County through 6 p.m. Monday. Beginning at noon Sunday, the advisory expands to include additional portions of eastern Wyoming and western Nebraska, also remaining in effect until 6 p.m. Monday.
Afternoon highs are expected to range from 96 to 102 degrees, while overnight lows will only fall into the mid-60s to mid-70s, providing little relief from the heat. Areas included in the advisory include communities such as Cheyenne, Torrington, Douglas, Lusk, Wheatland, Harrison, Chadron, Alliance, Scottsbluff, Bridgeport, Kimball, and Sidney.
The extended period of hot weather could quickly lead to heat exhaustion or heat stroke, particularly for outdoor workers, older adults, young children, and anyone without access to air conditioning. Residents are encouraged to stay hydrated by drinking plenty of water, wear lightweight clothing, schedule strenuous activities during the morning or evening hours, and take frequent breaks in air-conditioned or shaded locations.
Pet owners should also ensure animals have access to fresh water and shade while avoiding hot pavement during the afternoon. Motorists should never leave children or pets unattended inside parked vehicles, where temperatures can become life-threatening within minutes.
The heat advisory remains in effect through 6 p.m. Monday, and additional heat-related alerts could be issued if temperatures remain above seasonal averages into next week.
