Tornado Touches Down in Marathon County

On Monday evening, a tornado made landfall in central Wisconsin, leading to emergency alerts for residents in the vicinity of Mosinee and Wausau.

At 8:04 PM CDT, officials confirmed the tornado's position, located five miles southwest of Mosinee and approximately 17 miles south of Wausau, moving eastward at a speed of around 40 mph. The University of Wisconsin-Stevens Point disseminated warnings, urging individuals in the affected regions to relocate to the lowest level of a sturdy structure and avoid windows.

Meteorologists Analyze Tornado Formation

Meteorologists Discuss Unusual Landspout Formation

Earlier that evening, meteorologists noted that some tornado warnings issued near Wausau were related to landspouts, a type of tornado that forms differently from the larger supercell tornadoes typically associated with severe thunderstorms. Weather experts explained that landspouts occur when rapidly rising air stretches existing rotation near the ground, rather than developing from a rotating supercell thunderstorm. Although generally weaker than classic supercell tornadoes, landspouts can still generate damaging winds capable of overturning vehicles, damaging structures, and uprooting trees. Some storm chasers remarked that the tornado's characteristics differed from a conventional supercell structure, with one observer noting that the radar signature did not initially suggest a tornado was imminent. Others found the situation unusual, as visual confirmation of the tornado reportedly occurred several minutes before official warnings were issued.
