A Freeze Warning is in effect from midnight to 8 a.m. Monday for Jackson Hole, Star Valley, and surrounding areas in western Wyoming. Temperatures are expected to drop to the low 20s overnight Sunday, with the coldest spots near Bondurant reaching 23°F.
The warning includes areas like South Lincoln County, the Upper Green River Basin, and nearby foothills, impacting cities such as Jackson, Afton, Kemmerer, Pinedale, and Cokeville.
Cold Temperatures Expected
Low temperatures will range from 26°F to 30°F across the area. While June freezes are rare, they can happen, particularly in higher elevations. This could be one of the coldest late-June mornings in the region since 2020.
Protect Sensitive Plants and Outdoor Plumbing
Residents should be cautious about sensitive vegetation and unprotected outdoor plumbing. Those in areas like Alpine and Star Valley Ranch should cover plants or bring them inside to prevent frost damage.
People in rural areas should also check irrigation lines and hose connections to avoid freezing and potential damage.
Looking Ahead
Although the Freeze Warning expires at 8 a.m. Monday, cooler-than-average temperatures are expected to persist into the early part of next week.
