What happened

The episode as NWS MPX wrote it up.

A line of severe thunderstorms that developed across South Dakota and Nebraska during the afternoon of Thursday, May 12th, was a classic bow echo that surged north and east across western Minnesota.

Temperatures in the mid to upper 90s along with dew points in the mid to upper 60s created ample instability for thunderstorms to develop ahead of a cold front, once the cap weakened during the evening. Despite fairly muggy dew points, the hot surface temperatures created inverted-V soundings that were primed for damaging wind potential. Thunderstorms came in three waves during the evening, as marginal shear values prohibited any long-lived or well-organized thunderstorms across the area.

Winds were measured by wind sensors at over 100 mph across portions of South Dakota, with a measured wind gust at Madison, Minnesota of 94 mph. There were also numerous measured wind gusts between 60 and 80 mph across west central and southwest Minnesota with embedded surges that produced a few tornadoes. The most concentrated area of damage based on reports of farm equipment, trailers, semis, trees, power lines, and other debris, occurred near the upper Minnesota River Valley, northward to Alexandria and Long Prairie.

Over Stevens County alone, structural damage was considerable as the majority of the damage was to farm outbuildings, sheds and grain bins. There were a few locations in the county where the main inhabited house or home structure did suffer loss of roof and siding and windows but those were more isolated in nature. Many locations had debris tossed a mile northeast from its parent location. Nearly 100% of the damage witnessed in Stevens county was consistent with a straight line wind event, with just one tornado crossing the southeast corner of the county.

Ten tornadoes were confirmed this day, with two in Lac Qui Parle County, including a house in Bellingham that had much of its roof removed. In northwestern Swift County, a tornado tipped over trailers and various farm equipment was heavily damaged. Two tornadoes were in Todd County, including one that moved through Clarissa. Two more were in Morrison County, and one was on the east side of Lake Alexander, where many trees came down on vehicles, sheds, and cabins. A tornado also occurred in Douglas County, on the northwest side of Alexandria, where EF2 damage was noted. The ninth tornado touched down south of Lowry in Pope County and was caught on video, and the tenth was in northwestern Stearns County, affecting the north side of Sauk Centre, and it was also caught on video.

Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
332 PM CDT Thu May 12 2022

.SHORT TERM...(This evening through Friday night)
Issued at 329 PM CDT Thu May 12 2022

Key Messages:

- Another round of potentially severe storms expected this
evening/tonight, although they will be weakening as they head east.

Storms have been ongoing all day in central Minnesota but are
exiting our CWA currently. A few cells have also gone up in northern
west-central Wisconsin as well which will move northeast out of the
area. A noticeable warm front is moving north through southern
Minnesota with 70s ahead of the front and some lower 90s behind it.
As a strong trough pushes north through the Dakotas, thunderstorms
are expected to break out late this afternoon in eastern South
Dakota and quickly merge into a line that will rapidly move across
the forecast area through midnight or so. With these initial storms
in a very unstable airmass and steep mid-level lapse rates, large
hail is possible but shear is not great and as the storms move east
it looks like an outflow boundary will move out ahead of the storms
as they move into central and eastern Minnesota and the storms should
weaken. The largest threat with these storms will be damaging winds
as they move east, with the biggest threat in western Minnesota with
the threat lessening to the east as the outflow boundary outruns the
storms. Wind Gusts will have the potential to reach 70 MPH or more
in western Minnesota. The outflow boundary and weakening
thunderstorms should reach the west Twin Cities metro around 9 or 10
pm, and by that point wind gusts may only be in the 40-50 MPH range.
There is still a good bit of uncertainty as to how strong the storms
will be as CAMs have been fairly consistent in rapidly weakening the
line of storms just as they reach the vicinity of the metro.

.LONG TERM...(Saturday through Thursday)
Issued at 329 PM CDT Thu May 12 2022

Saturday through Wednesday - The extended will be fairly quiet with
a quasi-zonal upper level flow setting up over the weekend.
Temperatures will trend cooler over the weekend but remain several
degrees above normal before turning closer to average next week. The
most significant  change will be the drier air that settles in
across the region. Model guidance has dew points in the 40s and 50s,
a far cry from the current Summer-like values. The EPS and GEFS
bring a surge of moisture towards the end of the forecast period.
This will bring our next meaningful chance for precip on Wednesday
and Thursday.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1207 PM CDT Thu May 12 2022

Thunderstorms in central Minnesota will continue moving off to the
northeast leaving terminals dry through the afternoon and early
evening. Another strong line of thunderstorms will move into western
Minnesota around 8 PM and head eastward, but as it does it will be
weakening. It looks like a gust front will form and race ahead of the
showers, and we will watch for this development which could bring
stronger winds across the area. After the initial stronger storms
pass there may be a few hours of -SHRA/-TSRA before we begin to clear
out. Winds will be mainly from the east ahead of a warm front moving
northward through the region, then become SE behind the front with
gusts into the 20s.

KMSP...Currently looks like the best chance for thunderstorms at the
terminal comes around 10 pm as a weakening line of storms moves
across. It is questionable how strong the storms will be at that
time, but it looks like a gust front will move out ahead of the
storms and may bring some gusty winds to around 40 MPH, but
confidence is not great. There could be a brief break in activity
after the initial storms, but then it looks like a few hours of
-shra/-tsra coming in behind.

/OUTLOOK FOR KMSP/

SAT...VFR. Chc PM -SHRA/MVFR. Wind SW to NW 10-15g25kts.
SUN...VFR. Chc PM -SHRA/MVFR. Wind W 10-15kts.
