Survey Summary:
NWS Damage Survey team confirmed a tornado touched down around
11:56 AM CDT in Appleton in urban southern Outagamie County and
moved south through northeast Winnebago County, causing damage
consistent with an EF3 rating to portions of Menasha, before it
dissipated over Lake Winnebago around 12:22 PM CDT. 

The tornado developed just north of Wisconsin Avenue in Appleton,
partially tearing the roof off houses and several businesses on 
Wisconsin Avenue consistent with EF0 damage and winds of 85 mph. 
The tornado strengthened south of Wisconsin Avenue to EF1 by
collapsing exterior walls to a warehouse building east of North
Perkins Street with winds of 110 mph. The tornado continued
producing EF1 damage to warehouses, retail buildings and strip
malls as it continued south to College Avenue. The tornado
strengthened to EF2 south of College Avenue near South Perkins
Street by buckling the roof purlins to a metal building structure
with winds of 118 mph. The tornado continued to produce
EF1 damage through the rest of southern Outagamie County, by
snapping and uprooting trees as well as damage to residential
buildings, reaching the county line around 12:00 PM CDT as it
crossed the Fox River while widening to around 1000 yards.

The tornado entered northeastern Winnebago County around 12:00 CDT,
producing EF1 damage by snapping and uprooting trees and damaging
residential buildings just south of the Fox River.  The tornado
continued to widen and eventually strengthened again to
EF2 damage just south of Palisades Drive by uplifting significant
portions of the roof deck and collapsing garage doors to
residences with winds of 120 mph. The tornado continued to
strengthen and widen, reaching a width of 1400 yards and
producing EF3 damage to a well-built low-rise brick building just
north of Highway 10 in Menasha. At this location, significant
damage occurred to the exterior walls and some interior walls
with winds of 140 mph.

The tornado path then narrowed south of Highway 10 in Menasha to 
just below 1000 yards, producing pockets of EF2 damage along and 
just south of Midway Road by collapsing an entire roof with winds 
of 125 mph. EF2 damage was also observed east of highway 10 near 
Airport Road with the collapse of the exterior walls of a small 
professional building and winds of 135 mph. The tornado continued 
south and damaged the bleachers at Calder Stadium east of Racine 
Road, consistent with EF2 damage and winds of 120 mph.

The tornado widened again as it tracked south, reaching its maximum 
width of 1500 yards between 5th and 6th street in Menasha between 
Little Lake Butte des Morts and northern Lake Winnebago.  The 
tornado again reached EF3 intensity just south of this area, 
between Plank Road and 3rd Street. In this area a car was flipped 
over, there was a collapse of exterior walls of a small retail 
building, and a house was destroyed with winds of 140 mph.

The tornado continued south, crossing the Menasha Channel and 
producing EF2 damage to eastern Doty Island east of Smith Park 
with large sections of roof structures removed to residential 
structures along with snapped trees and exterior walls collapsed 
on one residence with winds of 130 mph. The tornado then tracked 
over Lake Winnebago passing east of Neenah Point.  Although the 
tornado at this point mainly stayed over the water, it did clip 
Davis Point, producing EF0 damage by uprooting trees with winds 
of 85 mph. The tornado continued south and eventually dissipated 
over Lake Winnebago somewhere east of Perkins Point.
