The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cheyenne, WY wrote its last area forecast discussion before this red flag warning went out at Sep 10, 11:55 AM CDT, 32 minutes earlier.
Area forecast discussion, Sep 10, 11:55 AM CDT, 32 minutes before
Area Forecast Discussion National Weather Service Cheyenne WY 1055 AM MDT Mon Sep 10 2018 .SHORT TERM...(Today through Wednesday) Issued at 215 AM MDT Mon Sep 10 2018 Main concern this period will be with Fire Weather conditions over the next few days in an otherwise warm and dry weather pattern. Westerly upper flow over the region today will turn slowly to southwesterly tonight and Tuesday then hold through Wednesday. Mainly sunny skies are expected today with some high clouds possibly drifting over western parts of the CWA. A couple weak impulses will lift northeast into the northern plains late Tuesday and again late Wednesday. The first one could set off a few showers or weak storms over the Neb Panhandle late Tuesday. Otherwise, these impulses will cause lee troughing to occur over the high plains which in turn will cause some increase in winds over western parts especially on Wednesday. .LONG TERM...(Wednesday night through Sunday) Issued at 230 AM MDT Mon Sep 10 2018 A warm and dry southwest flow aloft will prevail through the end of the week. Lee side surface trough over the high plains will promote gusty southwesterly winds each afternoon and early evening. These conditions will promote High fire danger for much of southeast Wyoming. Model differences appear this weekend, with the Euro pulling a upper trough across the northern CONUS, and the GFS holding a upper ridge over the central Great Plains. Consensus favors the Euro for cooler temperatures this weekend. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1050 AM MDT Mon Sep 10 2018 VFR conditions next 24 hours and beyond. Winds are going to be increasing Tuesday from the southwest and could become gusty. && .FIRE WEATHER... Issued at 215 AM MDT Mon Sep 10 2018 Concerns will exist across mainly southeast Wyoming for the next few days, particularly by Weds when stronger winds may occur over western districts, combining with low afternoon RHs. Warm and dry weather will continue pretty much for the entire week. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None. NE...None. && SHORT TERM...RE LONG TERM...MAJ AVIATION...GCC FIRE WEATHER...RE
