Cooperstown Tornado on July 5, 1994
The atmosphere during the afternoon of July 5, 1994, was very unstable, as a very warm and humid airmass covered the region. A storm formed south of Green Bay around 4:00 pm CDT and moved east. As the thunderstorm encountered a lake breeze near the Brown-Manitowoc County line, it increased in intensity, eventually producing two tornadoes.
Radar
The NWS Green Bay Doppler radar was not yet operational in July 1994 (it came online in early 1995). However, the newly installed radar at NWS Milwaukee/Sullivan captured a long-range glimpse of the storm.
