...NWS DAMAGE SURVEY FOR 05/30/2022 TORNADO EVENTS - UPDATE #2...

...SIX TORNADOES CONFIRMED FROM GRANT COUNTY THROUGH WADENA COUNTY
MN...

.UPDATE...This update combines information on 5 tornadoes
previously identified in 2 prior statements, plus 1 additional
tornado not previously identified. 

.OVERVIEW...A cluster of storms developed in westcentral MN and
evolved into a Mesoscale Convective System /MCS/ with a Mesoscale
Convective Vortex /MCV/ which tracked to the north-northeast into
northwest MN and an associated squall line which propagated
towards the northeast and east. The squall line appears to have
developed broad areas of extreme downburst winds along with
a number of embedded tornadic circulations, characteristic  of a
Quasi-Linear Convective System /QLCS/. Progression of the line
ranged from 70 to 90 mph, with commensurate downburst wind 
speeds across a several county area. 


.TORNADO #1... South Elbow Lake Tornado

Rating:                 EF-2
Estimated peak wind:    120 mph
Path length /Statute/:  6 miles
Path width /Maximum/:   350 yards
Fatalities:             0
Injuries:               0

Start date:             May 30 2022 
Start time:             414 pm CDT
Start location:         5 W Barrett / Grant County / MN
Start Lat/Lon:          45.8787 / -95.9972 

End date:               May 30 2022
End time:               419 pm CDT
End location:           3 SE Elbow Lake / Grant County / MN
End lat/lon:            45.9697 / -95.9313

SURVEY 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.


.TORNADO #2... West Elbow Lake Tornado

Rating:                 EF-2
Estimated peak wind:    115 mph

SURVEY SUMMARY: 
The tornado was wrapped in damaging downburst winds and rain.
Several wooden power poles were snapped along the tornado path,
while numerous ash, spruce, cottonwood, and willow trees were
snapped or uprooted at farmsteads. At one location, 6 of 8 steel
grain bins were popped off their slabs, tumbled and crushed over a
mile long trajectory. Multiple wooden and/or metal storage sheds 
were peeled open with portions of roofs and walls carried 
downwind. Towards the end of the tornado cycle the storm devolved 
into a broader downburst wind pattern that continued to propagate 
to the northeast, still generating 70 to 90 mph winds.

snapped across the eastern edge of Perham and along the western
and northern shores of Big Pine Lake. One garage had the front
doors blown in and the back wall blown out by the storm, though
the roof remained intact. The storm that produced the tornado
continued to produce damaging downburst winds of from 60 to 80 
mph over a broad area across Big Pine Lake and further downstream 
across Corliss Township.

End lat/lon:            46.4970 / -94.7791

SURVEY 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. In an
open area, roughly a mile downstream of the Bullard Bluff 
Campsite, one cabin was ripped opened, with the roof completely 
gone and the exterior walls caved in. Damage continued across the 
Crow Wing River and across CR30 /the Cass County Line Road/ into 
Cass County.

developed roughly a half mike to the east of an earlier tornado
based on divergent tree damage tracks and supported by radar
depictions. The tornado snapped or uprooted several poplar, ash,
and spruce trees along its path.

EF Scale: The Enhanced Fujita Scale Classifies Tornadoes into the
following categories.
