June 24th, 2023 Severe Event with multiple Tornados

Overview

Surface low pressure system tracked across the North Dakota/South Dakota border creating and environment supporting the threat for low top supercells in Southeastern North Dakota into adjacent West Central Minnesota. Several low top supercells developed and tracked along portions of Minnesota Red River Valley. Portions of Norman, Polk, Becker, and Mahnomen counties saw multiple tornadoes. Several uprooted or snapped trees, house/garage/barn, and 2 wooden power were damaged where an EF2 tornado tracked through Mahnomen county along and then just east of Hwy 59. Several other tornadoes tracked through Norman, Becker and western Polk county, but luckily stayed in fields and did little to no damage. Large hail and damaging winds accompanied some of the storms, with quarter size hail being reported in Clearwater, Hubbard, and Wadena counties. Heavy rainfall and training thunderstorms generated flash flooding in Clearwater and Pembina counties during the evening and overnight periods.
