Cook County News-Herald

Frequent and heavy rainfall during the first half of June 2008 plagued the Midwest with devastating urban flooding, disastrous agricultural impacts, and major impediments for the transportation. Although the most stricken states were Wisconsin, Iowa, Indiana, and Missouri, some Minnesota communities shared in the pain.

The first half of June produced numerous rounds of severe weather and heavy rainfall in Minnesota. Three particularly heavy rainfall events led to notable urban flooding and damage to agriculture and infrastructure on the rural landscape:

Total precipitation for the first half of June exceeded five inches in portions of northeastern and southeastern Minnesota (see map). Eight or more inches of rain fell in sections of Freeborn, Mower, Fillmore, and Houston counties. Elsewhere across Minnesota, rainfall totals through June 16 topped three inches in most places. The historical average rainfall for this time period is approximately one inch per week. Therefore, early-June rainfall substantially exceeded the historical average in most locales (see map).
