In the Beginning...

The first Cheyenne Weather Office was established by the U.S. Signal Service in 1870. Sgt. Asa Dobbins was in charge and operated the station with a barometer, self registering anemometer, wind vane, and wet and dry bulb temperatures. He recorded weather information from 1870 till 1878.

About Cheyenne...

Cheyenne is located in the southeast corner of Wyoming at an elevation of 6,120 feet. The surrounding country is mostly rolling prairie. The elevation climbs steadily to the west to a ridge of about 9,000 feet, approximately 30 miles west of Cheyenne. The ridge is part of the Laramie Mountains and is one of the ridges of the Rockies, extending in the north-south direction. The current population has been on the rise since the early 2000s following the oil boom, currently the population is slightly over 62,000.

The Weather Service in Cheyenne provides forecasts for Southeast Wyoming and the Nebraska Panhandle. Some of the products that are issued include: severe thunderstorm and tornado warnings, flash flood watches/warnings, high wind watches/warning, winter weather watches/warning, aviation, and fire weather forecasts.


Forecast Area

NWS Cheyenne Forecast Area

All of the forecasts provided get produced by the on station forecasters. The office is staffed 24 hours, 7 days a week, everyday. The forecasters are constantly monitoring the latest weather data, local television stations, and surrounding offices to ensure the accuracy and consistency of the weather forecast.

The Forecast...

We issue 7 day forecasts for southeast Wyoming and the Nebraska panhandle. To product these forecasts the forecasters use the Advanced Weather Integrated Processing System (AWIPS) to analyze computer model forecasts, radar information, satellites, and much more. In addition to a 7 day forecast, the forecasters are monitoring for a need for any watch, warnings, or advisories.


Also, the forecasters issue a fire weather and aviation forecast. Aviation forecasts are produced for several airports including: Cheyenne, Laramie, Rawlins, Chadron, Scottsbluff, Sidney, and Alliance. The fire weather forecasts are especially important to help fight wildfires

Watch, Warnings, and Advisories

Forecasters issue watch, warnings, and advisories during weather events that call for additional precautions.


Example watch and warning

Watches are issued when conditions are favorable or for events the will begin in the next day or two. Watches can be issued for many different types of weather events such as: severe thunderstorm, tornado, floods, high winds, fire weather, and winter weather. Watches are designed to ensure that there is plenty of time to prepare and take the necessary precautions before the warning is issued.


Warnings are much more serious and are issued when the event is expected to begin soon or currently observed. Warnings are urgent and action should be taken immediately.


In addition to the watches and warnings, the weather service also issues advisories. These are generally not life threatening and not as severe. Advisories are issued when there is to much uncertanity in the forecast and is to far out to issue a watch or a warning.


Most of the watches and warning are from the local forecast office. Although, in the event of severe thunderstorms watches are done in collaboration with the Storm Prediction Center (SPC) in Norman, OK. After the watch is issued by the SPC, the local forecast office makes decisions and monitors the radar to make the decision on any warnings that need to be issued. All other watches and warning originate locally.
