May 30, 2022, Memorial Day Severe Weather

Overview

A strong area of low pressure across the Northern Plains lifted a warm front across the Northland on Memorial Day morning. Showers and storms moved through during the morning hours with the atmosphere recovering during the afternoon hours. A few of the storms were severe during the morning and produced small hail and tree damage. An arc of thunderstorms developed across southwestern Minnesota and adjacent areas of Nebraska, South Dakota and Iowa by the mid-afternoon hours and moved to the northeast and across the Northland for the late afternoon and evening hours. These storms were much stronger and contained very strong winds that produced widespread damage across the region. Additionally, there were a few embedded tornadoes with the storms with the strongest tornadoes producing EF-1 damage in the Deer River and Hinckley areas.

Tornado - Poplar Township, MN
Cass County, MN

Date	May 30, 2022
Time (Local)	5:37 - 5:45 PM
EF Rating	EF-1
Est. Peak Winds	105 mph
Path Length	4.3 miles
Max Width	500 yards
Injuries/Deaths	0/0
Summary: A tornado caused damage in southwest Cass County, mainly across Poplar Township. The tornado began near the Poplar Cemetery and tracked north-northeast. Around a dozen power poles were snapped near the base along 60th St SW to the west of Highway 64 along with numerous tree damage, including several very healthy pine trees with trunks 12-18 inches in diameter snapped at the base. A small piece of farm equipment was also tossed roughly 100 yards. Significant tree damage was observed along Highway 64 around the intersection of 56 St SW, with damage continuing to the northeast into a wetland/bog-type landscape that was inaccessible. The end location of this tornado is estimated and may be revised based on high resolution satellite imagery.

Tornado - Cohasset, MN
Itasca, MN

Date	May 30, 2022
Time (Local)	6:44 - 6:46 PM
EF Rating	EF-0
Est. Peak Winds	85 mph
Path Length	1.0 miles
Max Width	40 yards
Injuries/Deaths	0/0
Summary: A brief tornado started near the intersection of County Road 63 and Becker Road. The tornado tracked north-northeast, sporadically knocking down trees along the way. While the tree damage was not as significant as other storms on this day, drone imagery provided by a spotter depicted a very clearly convergent signature in the tree damage. The most significant damage from this tornado was the partial lifting off of a roof from a two story home, though no broken windows were noted and otherwise shingle damage appeared very minor. Sporadic tree damage continued in a path to the north towards the Mississippi River where the damage path appeared to end.

Tornado - Deer River, MN
Itasca, MN

Date	May 30, 2022
Time (Local)	6:46 - 6:50 PM
EF Rating	EF-1
Est. Peak Winds	107 mph
Path Length	2.5 miles
Max Width	150 yards
Injuries/Deaths	0/0
Summary: A tornado produced a path of damage through the city of Deer River, with damage to numerous homes and businesses. The tornado likely began somewhere just south of Highway 2, though a precise location was difficult to determine due to a lack of damage. The first damage observed was a camper/RV that was in a parking lot south of Highway 2 which was tossed across the highway into the parking lot of a furniture store building just north of the highway. The furniture store building had all of its south facing windows blown out with damage to the front facade and some evidence of roof lift on the flat portion of the roof. The building also lost part of a gabled metal roof. A metal shed/outbuilding in the parking lot was completely destroyed. To the north, a two story building that includes a funeral home and post office had evidence of roof lift. Continuing north through the residential streets numerous trees were downed and several outbuildings, sheds and garage buildings, sustained significant damage, with some collapsing and others sliding off their foundations. This damage continued north- northwest, crossing State Highway 6 around 7th Ave. Damage to the ball fields north of town are believed to be part of the tornado’s path, with a small outbuilding and dugouts being destroyed and damage sustained to the metal chain link fence. Tree damage continued onto private property to the northwest, with the end of the tornado path estimated to be near or just south of County Road 142.

Tornado - Hinckley, MN
Pine, MN

Date	May 30, 2022
Time (Local)	7:50 - 7:54 PM
EF Rating	EF-1
Est. Peak Winds	95 mph
Path Length	3.3 miles
Max Width	300 yards
Injuries/Deaths	0/0
Summary: Damage sustained to a fast food restaurant in Hinckley, including broken windows, a damaged rooftop HVAC unit, and evidence of metal flashing damage, is believed to be the beginning of a tornado that then tracked across Interstate 35 in a north-northwest direction, crossing the railroad tracks near 7th St NE. The majority of the damage was uprooted trees with several snapped along the way. Aerial imagery provided by the Pine County Sheriff’s Department shows fairly weak but convergent tree fall between I-35 and near Highway 61 and Owl Drive. A distinct intensification where the treefall becomes much more extensive and a metal roof section was lifted off a local business near Owl Drive. The tornado then tracked across Highway 61 and traversed north causing mainly tree damage with at least one home losing some roof shingles. The end of the tornado path is estimated due to the track moving into a much less wooded wetland area. NWS Duluth sincerely appreciates the drone imagery provided by the Pine County Sheriff’s Office to aid in the assessment of this storm damage.

Radar

Header


Radar overview of the Poplar Township tornado. Additional tornadoes were found upstream from this one, but a continuous damage path across the county/CWA line was not found.	Radar overview of the Deer River and Cohasset tornadoes. Note that the radar was having dealiasing issues in the area of interest, making it difficult to see pertinant features. This area is ~80 miles from the radar and the lowest scan is ~5100'. The processes for QLCS tornadogenesis usually occur ~1600' or lower, so the radar is overshooting the area of interest in the storm.

Radar overview of the Hinckley tornado. Hinckley is ~65 miles from the radar with the lowest beam elevation ~3500', so the radar is again overshooting the area of interest. However, we can see a descending rear inflow jet approaching from the southwest. This feature is believed to have played a part in tornadogenesis in addition to bringing damaging straight-line winds to the central part of Hinckley.	Radar overview of a null tornado case near Swatara. There is a CC drop nearly colocated with some broad circulation which may be a TDS. However, these features were located in an area of low reflectivity ahead of the storm and are most likely cause by side lobe contamination.

   Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1125 AM CDT Mon May 30 2022

   Valid 301630Z - 311200Z

   ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS
   AFTERNOON/EVENING FROM EASTERN SD INTO MN...

   ...SUMMARY...
   Numerous severe thunderstorms are forecast across parts of the
   Northern Plains and Upper Mississippi Valley, with more scattered to
   isolated activity southward into the central Plains today into
   tonight. Large to giant hail, 60-80 mph gusts, and a few
   long-tracked, intense tornadoes are possible.

   ...A substantial threat for severe storms with all hazards is
   expected this afternoon/evening from eastern South Dakota into
   Minnesota...

   ...Eastern SD into MN though late evening...
   A midlevel shortwave trough and associated 70-90 kt midlevel jet
   will progress quickly north-northeastward from western KS/NE toward
   the upper MS Valley by tonight.  An associated 992 mb surface low in
   central NE as of late morning will develop quickly
   north-northeastward across eastern SD to near the ND/MN border by
   early tonight.  Scattered elevated storms, some with large hail,
   will likely persist through the day in the warm advection zone to
   the north of the warm front across eastern SD into southwestern MN. 
   However, the warm sector with mid-upper 60s dewpoints now across
   eastern NE/western IA will spread northward during the day, with
   increasing potential for surface-based storm development near and
   just ahead of the surface cyclone and ejecting midlevel trough by
   midday/early afternoon.

   It appears the convection will begin as clusters by midday across
   east/southeast SD, and expand quickly northeastward into
   central/northern MN by late afternoon/evening.  All hazards can be
   expected with the surface-based storms during the afternoon, in an
   environment favorable for fast-moving supercells.  However, there
   are some concerns about mixed convective mode/bowing segments given
   potential storm interactions and strong forcing for ascent. 
   Deep-layer vertical shear will be quite strong (effective shear in
   excess of 65 kt), with long hodographs and low-level, clockwise
   curvature (effective SRH of 300-400 m2/s2).  These wind profiles, in
   combination with midlevel lapse rates greater than 8 C/km and MLCAPE
   of 2000-3000 J/kg, will support the threat for a few long-tracked,
   intense tornadoes and very large hail with any semi-discrete
   supercells.  As previously mentioned, there will also be some
   potential for storm interactions and upscale growth into line
   segments capable of producing significant outflow gusts up to 80
   mph, given the very strong environmental wind profiles.
