In late September, Colorado ski resorts began preparing for the upcoming winter season as dropping temperatures and high-elevation snowfall signaled the potential start of snowmaking operations. Facilities such as Arapahoe Basin, Loveland Ski Area, and Keystone Resort monitored weather conditions, specifically seeking wet bulb temperatures below 26-28 degrees Fahrenheit to initiate the process.

By late October, warm weather conditions slowed snowmaking progress, leading to delays in anticipated resort openings. While some snowmaking began around October 14 following a light snowstorm, meteorologist Joel Gratz described the conditions as “marginal.” Consequently, several major resorts updated their projected opening timelines, with dates ranging from late October through late November.
