Table: Drummond, Wisconsin Precipitation Frequency Estimates
Isolated regions near Solon Springs, Wisconsin, saw rainfall totals up to 12 inches on Sunday, June 17. (The Drummond Weather Station, to the east of Solon Springs and near the center of heaviest rainfall is starred in the map above.)
Rainfall totals between 6 and 12 inches in just a few hours in this region are so rare you would expect totals this high only once every 100 to 1000 years, according to station records spanning 1948-2005 in Drummond, Wisconsin. However, as the climate warms, a warmer atmosphere can hold more moisture, which increases the risk of extreme precipitation.
