            NWS Storm Survey: Estimated 90mph downburst
            winds. Appears to be from downburst winds as
            most damage appears to be pushed down with
            no signs of lofted debris. The hardest hit
            area was in the Forest Subdivision west of
            Veterans Memorial Park. This area sits at a
            higher elevation and it looks like the wind
            caught a lot of pine trees and either
            uprooted or snapped them. The two buildings
            that had direct wind damage to them were the
            Milwaukee Valve facility and a Sanitation
            building. The Sanitation building had its
            north wall blown in, but none of the roofing
            material. For the Valve building, it appears
            that the corner of a roof peeled back with
            some of the insulation blowing onto the
            apartment complex to the southeast. This is
            the only material that was seen lofted but
            its possible that due to the higher level of
            the building that the insulation just blew
            sideways. Radar also is inconclusive for any
            sort of rotation or debris signature.

04/14/2026                   Dane               WI   NWS Storm Survey

            NWS Storm Survey: EF-1 tornado, estimated
            peak winds of 105 mph. 75 yards wide.
            Tornado appears to have started west of I-39
            along Church Rd where it tracked to the
            north side before hitting a farmstead along
            Highway 73. Two metal barn structures were
            completely destroyed with sheet metal from
            these buildings found in the trees in the
            far farm hill. A cement silo was also lifted
            up and had 3 large chunks of the cap broken
            off of it. The tornado appears to have gone
            southeast toward County Road A before ending
            near Woodside School Rd. Extensive straight
            line/rear flank downdraft damage occurred
            about a mile or two to the south of the
            tornado with one farm shed destroyed along
            Hwy 73 south of Thronson Rd. Sheet metal
            from this building appeared to be tumbled
            into the nearby field to the east.
