will also be possible with embedded circulations, as well as large

hail in the next few hours with lingering supercell structures.



The severe thunderstorm watch area is approximately along and 55

statute miles north and south of a line from 70 miles west northwest

of Wausau WI to 30 miles northeast of Manitowoc WI. For a complete

depiction of the watch see the associated watch outline update
