Where in the world is F.E. Warren?

Francis E. Warren Air Force Base, Wyo., is easy to find. The base sits on the western edge of the city of Cheyenne, Wyo., which is located in Southeast Wyoming, and is about nine miles north of the Colorado border and just off of Interstate-25. Interstates-80 and 25 intersect about three miles south of the main gate. The base and town are roughly two hours north of Denver, and seven to 10 hours from Salt Lake City or Omaha, Neb.


Cheyenne, located near the Front Range of the Rocky Mountains and on the high plains, has four distinct seasons and, at times, rapidly changing weather conditions. Located in a fairly dry region of the country, the base receives about 14 inches of moisture per year in the form of rain or snowmelt and has an average winter snowfall of 52 inches. Snowfall is common nine months out of the year due to the high plains environment (more than 6,000 feet above sea level.) The first snowfall of the season typically occurs in late September and the last snowfall occurs in May.

Winter months are usually dry and windy with wind gusts commonly more than 50 mph. Blowing and drifting snow create particularly hazardous conditions for winter travel. All of the major highways leading through Cheyenne occasionally close due to severe winter weather. Average winter temperatures range from the 30s during the day to teens overnight. Cold snaps that can plunge temperatures and wind chills below zero are typically short lived.

Spring and summer seasons are the wettest times of the year with more than two inches of moisture per month from April to July. Severe thunderstorms occur in the late spring to summer months and can result in flash flooding conditions, large hail and even occasional tornadoes. The peak of the tornado season along the Front Range is June, while the greatest flash flooding potential exists in July and August. Average summer temperatures are pleasant, due in part to the low humidity, with most days in the low 80s for highs and 50s for overnight lows.

The bottom line is the weather in Cheyenne can and will change rapidly, no matter what the season. Always be prepared.
