The radar
The Minot AFB radar (KMBX), 167 km from the middle of the area, began a volume at 21:53 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Severe Thunderstorm Warning
National Weather Service Grand Forks ND
452 PM CDT Tue Jun 2 2026
The National Weather Service in Grand Forks has issued a
* Severe Thunderstorm Warning for...
East central Towner County in northeastern North Dakota...
Western Cavalier County in northeastern North Dakota...
* Until 545 PM CDT.
* At 451 PM CDT, severe thunderstorms were located along a line
extending from near Hannah to 7 miles east of Cando, moving east at
25 mph.
HAZARD...60 mph wind gusts and quarter size hail.
SOURCE...Radar indicated.
IMPACT...Hail damage to vehicles is expected. Expect wind damage
to roofs, siding, and trees.
* Locations impacted include...
Munich, Hampden, Clyde, Alsen, Wales, Sarles, and Calio.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Remain alert for a possible tornado! Tornadoes can develop quickly
from severe thunderstorms. If you spot a tornado go at once into the
basement or small central room in a sturdy structure.
For your protection move to an interior room on the lowest floor of a
building.
Intense thunderstorm lines can produce brief tornadoes and widespread
significant wind damage. Although a tornado is not immediately
likely, it is best to move to an interior room on the lowest floor of
a building. These storms may cause serious injury and significant
property damage.

Area Forecast Discussion National Weather Service Grand Forks ND 256 PM CDT Tue Jun 2 2026 .KEY MESSAGES... - There is a level 2 out of 5 risk for severe thunderstorms this afternoon and evening over the Devils Lake Basin into the northern Red River Valley. Weaker showers and thunderstorms could get as far east as the Red River later tonight. - There is a level 2 out of 5 risk for severe thunderstorms Wednesday afternoon and evening over the central and southern Red River Valley. && .DISCUSSION... Issued at 256 PM CDT Tue Jun 2 2026 ...Synopsis... Southwesterly flow aloft with weak embedded shortwaves moving through the Northern Plains will continue through tonight and tomorrow, with the upper low moving every slowly across southern Canada. South to southeasterly winds will continue through tonight, then the surface trough axis will push into the CWA by tomorrow night. The rest of this afternoon and evening looks to remain active, with another round tomorrow. The upper system finally starts to pull eastward on Thursday. A weak shortwave on Friday, but then upper ridging builds into the Plains and Midwest over the weekend. Warmer than average temperatures should return. Southwesterly flow aloft again for the first part of next week, so warm temperatures will continue and chances for a more active convective pattern increase. Devil is in the details. ...Severe potential in northeastern ND tonight... Southeasterly winds have brought dew points into the low 60s across many locations in eastern ND, and with mostly sunny skies temperatures have climbed into the 80s. A fair amount of cumulus extending from the James River Valley up into the Devils Lake Basin. SPC mesoanalysis page has 2500 J/kg of ML CAPE, and even higher surface based values. Deep layer bulk shear is pretty weak south of Highway 2, but around 35 to 40 kts was enough to get a few isolated supercells going that have been moving off into Canada. The main trough axis and cold front are still well to our west, with some modest convection so far. Many of the CAMs have convective intensity in that area increasing in the next few hours, which fits the front moving into the region of high instability. The storms out west should become linear as they move into our western counties later this evening. Damaging winds and hail will be the main threat, but will have to watch the 0-3km shear in case the line become perpendicular to the shear vector and get a brief tornado spin-up. Heavy rain could be an issue as we head into tonight and early tomorrow, as there will be some training as the upper flow lines up nearly parallel to the surface boundary. With 1.2 inches of PWATs, backbuilding storms could become a problem even with our recent fairly dry conditions. ...Severe potential on Wednesday... Weakening showers and thunderstorms will be ongoing tomorrow morning near the Red River, so that may have a bit of an impact on how things develop tomorrow afternoon. Some ensemble members have CAPE approaching 2000 J/kg in southeastern ND, and deep layer bulk shear should be a bit better further south than today with 30-40 kts. CIPS and machine learning both have some 15 percent probabilities of severe impacts. HREF probabilities for updraft helicity tracks have a bullseye over SD, but over 70 percent chance for 4 hour max UH tracks nosing into Ransom and Sargent counties. Main threat will be in southeastern ND into the southern and central RRV south of Highway 2. Large hail over 2 inches will be possible, but can't rule out a tornado spin up or some damaging wind. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1232 PM CDT Tue Jun 2 2026 VFR conditions currently and for the next several hours, as convection has already started to develop between KDVL and KGFK. Cells are pretty isolated so far and not expected to impact the airports yet. Additional showers and thunderstorms will move into the KDVL area later this evening and possibly KGFK by late evening to the early morning hours. Less certain how far south and east to go as the convection weakens, but have some prob30 for showers at KFAR and KTVF late tonight into tomorrow morning. Some of the models bring in some MVFR ceilings behind the convection, but only certain enough for KDVL to include in the TAFs at this point. Winds may be impacted by convection, turning to the west or even northwest for a time in northeastern ND, but will return to southeasterly. Gusts should remain below 25 kts except near thunderstorms. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && DISCUSSION...Lynch AVIATION...JR
