Another round of scattered showers and thunderstorms returns with gusty outflow wind 35 to 45 mph being the primary hazard. Coverage is greatest between 1 PM and 6 PM, especially along and east of the Continental Divide, before coverage and intensity decreases by 10 PM. Elevated fire weather conditions may be possible over portions of southern Wyoming through 8 PM, due to low relative humidity and gusty surface wind, including those from showers and storms. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Sunday and Monday...Daily chances for afternoon showers and thunderstorms. The best chances will be in central and northern Wyoming with lesser chances elsewhere. Low minimum relative humidity and breezy westerly wind persists across southern Wyoming. These conditions are expected to gradually spread north leading to elevated to near-critical fire weather conditions to start the week. Tuesday through Friday...The combination of gusty westerly wind, above normal temperatures, and low relative humidity will create elevated to perhaps critical fire weather conditions across portions of southwest and central Wyoming. .SPOTTER INFORMATION STATEMENT... Weather spotters are encouraged to report significant weather conditions according to Standard Operating Procedures.
