RIVERTON, Wyo. – Central Wyoming heads into Thursday with strong winds, fire danger, and the threat of weekend thunderstorms impacting daily life. Drivers and residents across Fremont and Johnson Counties should prepare for rapid weather changes, with gusts topping 30 mph in some areas.
According to the National Weather Service in Riverton, elevated fire danger remains a concern this afternoon in southern Wyoming. By Thursday, winds strengthen in the northern Big Horn Basin and Johnson County, especially during afternoon hours, making travel on U.S. Highway 26 more hazardous for high-profile vehicles.
Saturday and Sunday bring another shift. Forecasters say scattered showers and thunderstorms will spread west to east, increasing the risk of lightning and localized flooding. Outdoor plans, including high school football games and weekend travel, may be disrupted. Residents should monitor weather alerts and avoid unnecessary backcountry travel during storm windows.
Riverton itself faces hot and breezy conditions Thursday with highs in the mid-80s before cooler air arrives by Friday. Visibility issues from patchy smoke also linger midweek, potentially impacting outdoor activities.
Firefighters urge residents to avoid open burning and secure equipment that could spark grassfires. Extra caution is advised along rural roads where dry grass remains abundant.
Storm chances persist into early next week, with thunderstorm activity possible Monday and Tuesday. More advisories could follow as fall weather patterns strengthen across Wyoming.
