Cheyenne, WY – Dry, windy conditions are driving critical fire weather risk across eastern Wyoming today.
According to the National Weather Service Storm Prediction Center, a combination of low humidity and strengthening winds is expected to create dangerous fire conditions Friday afternoon across central and eastern parts of the state. Relative humidity values are forecast to drop as low as 10–20%, while sustained west to northwest winds reach 20–25 mph, with gusts up to 25 mph.
Meteorologists say warming temperatures, climbing into the 60s, are contributing to rapid drying of grasses and other fine fuels. Poor overnight humidity recovery has already left vegetation more susceptible to ignition and fast fire spread.
The highest concern is centered in eastern Wyoming, where “critical” fire weather conditions have been designated. Surrounding areas—including parts of western Nebraska, southwestern South Dakota, and the Wyoming Basin—are under “elevated” fire risk, where slightly lower wind speeds still overlap with very dry air.
Officials warn that any fire that starts could spread quickly under these conditions. Outdoor burning is strongly discouraged, and residents are urged to avoid activities that could spark flames, such as equipment use that generates heat or sparks.
Further north, including parts of southern Montana, elevated fire conditions are also expected, with wind gusts potentially reaching 30–40 mph due to strong atmospheric mixing.
These conditions are expected to persist through the afternoon and gradually ease later in the evening as temperatures cool and humidity recovers.
This setup may affect ranching operations, travel along open highways, and outdoor work, especially for those exposed to dry vegetation and gusty winds.
