Overview

On the evening of Friday, June 27, 2025, several supercell thunderstorms spawned numerous tornadoes and produced very large hail across central North Dakota. The first tornado touched down in Oliver County around 7:40 PM CDT. Less than an hour later, another tornado was spotted north of Crown Butte Lake in northeast Morton County. Then after nearly an hour and a half, 7 tornadoes were reported in the span of an hour, from around 10:15 to 11:15 PM CDT in Burleigh, Kidder, and Emmons Counties. The strongest tornado, which was rated an EF-2, caused damage to a farmstead west of Temvik in Emmons County. 2 of the other tornadoes touched down just to the north of the city limits of Bismarck, but only caused limited damage. In addition to the tornadoes, these storms produced very large hail, including 3.5 inch diameter hail from the same storm that produced the first tornado in Oliver County. While all the tornadoes and the largest hail reported were in south central North Dakota, severe thunderstorms impacted north central parts of the state as well. Several reports of golf ball to baseball size hail were received from McLean and McHenry Counties.

...NWS Damage Survey for 06/27/2025 Tornado Event...

Video evidence gathered from social media verifies that a supercell 
thunderstorm produced two tornadoes just north of Bismarck, North
Dakota, on the evening of Friday, June 27th 2025. The first 
tornado resulted in damage at a residence along 110th Ave NW. The
tornado tracked south, across the roadway and dissipated in an 
open field. The tornado lasted approximately 4 minutes. A second 
tornado then developed south of 110th Ave NW and drifted slowly 
southwest before dissipating in the same open field. The second 
tornado lasted approximately 5 minutes.

formed approximately 8 miles north of Bismarck. A storm survey 
found that the tornado developed just north of a residence on 
110th Ave NW, an east to west roadway. The tornado moved from north 
to south across the residence lot, causing significant roof damage 
to an outbuilding, toppling a covered trailer and snapping or 
uprooting a few trees. The tornado crossed 110th Ave NW and 
snapped several branches of a large cottonwood tree in the ditch 
on the south side of the roadway. The tornado then traveled a few 
hundred feet into an open field before dissipating. The damage 
found was consistent with EF1 tornado damage with estimated peak 
winds of 95 mph.

On the evening of June 27th, 2025, a supercell thunderstorm 
produced two tornadoes west of Temvik, North Dakota in Emmons 
County. According to eyewitnesses and video evidence, the first 
tornado touched down in an open field about 4 miles WSW of Temvik,
just to the west of 4th Ave SE at around 10:12 PM CDT. The 
tornado crossed the road to the east and impacted a residence 
consistent with EF1 damage and lifted after moving off to the 
northeast. The first tornado was on the ground for a little bit 
over a minute.

About five minutes later, a second tornado developed just to the 
south of another property around 3 miles W of Temvik. Damage was 
surveyed at the impacted residence, consistent with EF2 damage. 
The tornado continued to move off to the north and crossed 72nd 
St. SW before traveling another mile and dissipating over an open

pole before impacting a residence. Some roof covering damage, 
siding, and window/door damage was surveyed and the owner reported
a slight shift of the foundation. The tornado also destroyed a 
few outbuildings anchored with chains and produced significant 
damage to a large Quonset. The tornado threw a large stainless 
steel trailer around 250 yards east into a field and threw another
smaller trailer around 350 yards east, landing in a grove of 
trees. Damage was consistent with EF1 damage with peak winds up to

Survey Summary:
According to video evidence which lines up with radar data, a 
second tornado developed at 10:18 PM CDT just south of a residence
around 3 miles west of Temvik. The tornado picked up a large 
horse trailer and threw it around 150 yards north northeast into a
tree. The tornado then destroyed a new large metal workshop, 
small garage, and a large wooden barn. The workshop and garage had
both been anchored into concrete slabs. This damage was 
consistent with EF2 tornado damage with estimated peak winds of 
120 mph. The tornado also produced EF1 damage to the main 
residence just to the west. Significant roof covering damage was 
surveyed and a well built porch was blown off of the house. 
Widespread tree damage was noted to several hard and softwood 
trees around the property. The tornado then continued to move 
north along the general path of the driveway, snapping more 
hardwood trees to the east before crossing 72nd St SW. There were 
two more hardwood trees with large branches broken off just to the
north of 72nd St SW. According to satellite and radar data, the 
tornado continued to track north northwest for around another mile
before dissipating over an open field at approximately 10:30 PM 
CDT.

Environment

A fast moving shortwave trough aloft, combined with ample moisture from southerly flow at the surface, provided an active evening of severe weather across central North Dakota on June 27th 2025. The Storm Prediction Center (SPC) had a broad area of Slight Risk (level 2 out of 5) across central and eastern North Dakota. In the late afternoon update SPC upgraded to an enhanced risk (level 3 out of 5) in central North Dakota for an increased hail and tornado threat. With high amounts of surface based CAPE, and effective bulk shear with the vector perpendicular to the mentioned wave, SPC issued a Mesoscale Discussion for increased concerns for very large hail and a couple of tornadoes possible. A special sounding launched by NWS Bismarck confirmed these concerns, although initially showed a limited tornado potential. The synoptic sounding at 00z from NWS Bismarck showed increasing low level shear and storm relative helicity, thus indicating an increase to the tornado threat. This threat only increased through the evening as Significant Tornado Parameters increased (not shown). The first reported tornado near Hannover, ND occurred around 741 PM, with tornado reports continuing through the late evening. A Tornado Watch was issued for this event from about 520 PM CDT until 1 AM CDT for much of central North Dakota.
