Overview

A multi-round event of severe weather occurred on Monday, August 5, 2019. During the early afternoon hours, a severe thunderstorm produced very large hail (up to 4") from Watertown to Delano, Minnesota. The storm continued to produce large hail as it moved northeast through the northwest and northern portions of the Twin Cities metro.

Later in the afternoon, more storms developed across central Minnesota and moved southeast. The storms were initially discrete and more severe hail was reported in the extreme northwest metro. However, as the storms congealed into a line, severe wind gusts became the primary hazard. The southern portions of the Metro took the brunt of the severe winds as damage to numerous trees occurred.
