You can either provide a complete 6-character PIL/AFOS ID or provide
the 3-character base ID (e.g., AFD

408 FNUS55 KCYS 192014 FWFCYS Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska National Weather Service Cheyenne WY 214 PM MDT Wed May 19 2021 .DISCUSSION... Limited fire weather concerns given recent precipitation across the region and current green up of fuels. Thursday will feature mid teen humidities and wind gusts of 25 to 30 mph across central and west Carbon County. While this would normally indicate critical conditions, fuels remain saturated with low ERC values. Continued higher humidity and scattered wetting rains will occur through the end of the week and weekend. A warmer and drier pattern appears more likely next week.
