Hail, then winds, strike northern Minnesota, June 28-29, 2018

Two rounds of severe thunderstorms produced large hail and damaging thunderstorm winds across Minnesota’s Northland on Thursday June 28th and Friday June 29th, 2018.

The first wave of activity erupted during mid-morning and lasted into the afternoon on Thursday, along a warm front draped across the northern one-third of Minnesota. The isolated but powerful thunderstorms produced torrential rains and hail up to the size of ping pong balls. Hail was reported along a narrow arc including or near East Grand Forks, Crookston, Bemidji, Grand Rapids, and Sandstone. The storms dissipated during the late afternoon as calmer weather set in.

The calm was short-lived, however, and by early morning on the 29th, a long-lived thunderstorm complex with damaging winds raced into northwestern Minnesota at speeds of up to 70 mph. The accelerating storms produced 55-70 mph winds and a long swath of tree, power line, and even minor structural damage. The hardest hit areas were near Bemidji and Kelliher. Area radars showed that the system had a classical “bow echo” appearance, with the storms oriented along a curved or bulging line. This is a common appearance for severe thunderstorms that produce damaging winds.

Another interesting feature of this second storm system was its longevity, and especially the amount of time it spent producing strong winds. The complex of storms had originated in east-central Montana Thursday evening, and then tracked across North Dakota before getting to Minnesota. Sensors from west to east across North Dakota indicate the storms produced winds of 50-80 mph for several consecutive hours before entering Minnesota. Long-lasting, wind damage-producing thunderstorm complexes of this type are called “derechos” (pronounced “deh-RAY-cho”), and are considered to be a rare class of severe thunderstorms.

Following are storm damage reports gathered from the National Weather Service Forecast Offices in Grand Forks and Duluth.
