Review of the May 30, 2022 Wind and Tornado event over West Central Minnesota

Overview

All severe components came together on Memorial Day (Monday, May 30th) to be a dangerous severe weather day. Damaging winds and significant tornadoes looked to be the main threats, as a bowing line of severe thunderstorms lifted northeast through the lakes country of west central Minnesota during the afternoon and early evening. As it turned out, numerous reports of wind damage were received, with possible embedded tornadoes.

Tornadoes:

Overview: During the afternoon into early evening of May 30, 2022, a well organized, fast moving mesoscale convective system (MCS) tracked north-northeast through west-central and northwest Minnesota. This MCS developed broad areas of extreme downburst winds along with a number of embedded tornadic circulations, characteristic of a Quasi-Linear Convective System (QLCS). Evidence of six distinct tornadoes were found within the NWS Grant, Otter Tail, and Wadena counties within Minnesota. The progression of the line ranged from 70 to 90 mph, with commensurate downburst wind speeds across a several county area.

Tornado - South Elbow Lake Tornado
Grant County, Minnesota

Date	May 30 2022
Time (Local)	4:14 pm - 4:19 pm CDT
EF Rating	EF - 2
Est. Peak Winds	120 mph
Path Length	6 miles
Max Width	350 yards
Injuries/Deaths	0
Summary: This tornado was likely wrapped in damaging downburst winds and heavy rain. Numerous wooden power poles were snapped along the tornado path, including single poles and high voltage, double pole, x-braced, structures. This includes a nearly 2 mile long stretch of the double pole structures snapped along the East- West running 240th Street, as the tornado devolved into a much broader downburst wind pattern, similar to the nearly concurrent West Elbow Lake Tornado. Numerous ash, spruce, cottonwood, and willow trees were snapped or uprooted. Several steel grain bins were caved in, or popped off their foundations and crumpled in a downstream path. Multiple small wooden and/or metal storage sheds were peeled open with portions of roofs and walls carried downwind. The broader downburst wind pattern continued to propagate to the northeast, still generating 70 to 90 mph winds as it moved across Pomme de Terre Lake and into northeastern Grant County.

Summary: The tornado was likely wrapped in damaging downburst winds and heavy rain as it crossed from Todd County and proceeded in a north-northeast direction until it crossed into Cass County. numerous wooden power poles were snapped along the tornado path, including single poles and a couple of high voltage, double pole, structures. At least 3 center pivot irrigation system were tumbled and several farmsteads had roofing materials torn off of out buildings. Extensive pine tree damage was noted at the Old Wadena Campground, where swaths of trees from 300 to 400 yards wide were completed laid down in a curvilinear fashion by the storm, both there and at the downstream Bullard Bluff Campground. One park shelter at the OLd Wadena Campsite was completely destroyed.

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0 Weak 65-85 mph	EF1 Moderate 86-110 mph	EF2 Significant 111-135 mph	EF3 Severe 136-165 mph	EF4 Extreme 166-200 mph	EF5 Catastrophic 200+ mph

Wind & Hail:

Here are the peak measured wind reports from May 30th. It is worth mentioning additional and potentially higher wind gusts may not have been measured due to widespread power outages as a result of the strong wind gusts themselves.

Hail reports are shown in the Storm Reports section.
