Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska
National Weather Service Cheyenne WY
337 AM MDT Wed Aug 23 2017

.DISCUSSION...

Increasing moisture today and Thursday will bring a better chance
for showers and thunderstorms to the district through this time.
Wetting rains are a good possibility especially over the high
country, and gusty winds are likely with thunderstorms. Humidities
overall should remain around 20 percent or higher both days,
although western portions of Converse County could drop as low at
15% today. Winds here should remain light though. As a result,
fire weather concerns will remain minimal.
