####018065187#### FNUS55 KCYS 180705 FWFCYS Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska National Weather Service CHEYENNE WY 105 AM MDT Tue Aug 18 2026 .DISCUSSION... Minimal fire weather concerns anticipated today as afternoon minimum humidity values remain about 30 percent. Winds will be a touch breezy this afternoon across Carbon and Albany counties, but more moisture will be present across the region, limiting fire concerns. Concerns start to increase Wednesday onwards as afternoon minimum humidity values drop into the 15 to 20 percent range west of the Laramie Range and 25 to 40 percent east of the Laramie Range. Breezy conditions are anticipated across Carbon and Albany counties again, increasing the fire concerns. There is lower confidence on achieving three hours of consecutive Red Flag criteria west of the Laramie Range and with the moisture over the past few days, fires may be a bit more difficult to get going. Therefore, decided not to do any fire weather headlines for Wednesday at this time. However, elevated to near critical conditions will continue each afternoon through the end of the week.
