Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska
National Weather Service CHEYENNE WY
221 AM MDT Thu Apr 18 2024
.DISCUSSION...
The area will be under the influence of a cold and moist storm
system that will bring scattered rain and snow showers to much of
the region over the next several days. This will keep fire
weather concerns low as relative humidity values will be above
fire weather thresholds and for the area wide precipitation.
