The radar

The Fargo/Grand Forks radar (KMVX), 163 km from the middle of the area, began a volume at 23:46 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 tornado 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.

The nearest sounding before it

International Fa, MN (KINL), launched 12:00Z, 11.7 hours before the alert went out and 192 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Grand Forks, ND wrote its last area forecast discussion before this tornado warning went out at Jun 23, 6:31 PM CDT, 12 minutes earlier. Its key messages:

  • There is a level 2 out of 5 risk for severe thunderstorms this afternoon into early evening, mainly along and east of the Red River Valley. The main hazards will be hail up to the size of golfs balls and tornadoes.
  • Growing signal for strong to severe storms late this weekend into early next week.

.DISCUSSION...
Issued at 1233 PM CDT Tue Jun 23 2026

...Synopsis...

The system seen on water vapor imagery across southern Manitoba has
become occluded and will very slowly propagate east/southeast.
Large scale pattern will become zonal toward the end of the
week, and then transition to southwest flow aloft by early next
week as western CONUS troughing develops. Ensemble guidance in
good agreement with how the large scale pattern will evolve,
albeit with lower confidence in smaller scale features.

..Severe storm potential today...

Warm sector/theta-e ridge will be near or just east of the valley by
early afternoon, with CI anticipated along the leading edge of this
boundary early-mid afternoon. Given expected storm motion off the
boundary, anticipate discrete mode. Environment will be
supportive of supercell type storms (albeit low topped given
MLCAPE 1000-1500 J/kg) given effective bulk shear near 30 kts
and effective SRH near 200 m2/s2 (environment supportive for
stronger low level mesocyclones). Severe hail up to golf balls
anticipated given straight hodograph structure, lower freezing
level, and favorable mid level lapse rates. Also anticipate
tornadoes given the favorable low level dynamics. AI guidance
(Nadocast and Storm Net) back up this thinking.

The most likely scenario at time has the stronger discrete low
topped supercell storms developing early afternoon (1-3p) along
the eastern edge of the valley affecting much of northwest and
west central Minnesota through 6-7p. There should be 2-5 storms
at any given time. This is the period when low topped
supercells will bring the largest hail and tornado threat. There
is the potential for additional development closer to the sfc
low/upper low later in the afternoon affecting the northern
valley into northwest Minnesota, although more uncertainty
exists with this activity.

...Weekend into early next week severe potential...

The synoptic ingredients typical for producing severe storms in our
region will be in place - and conceptually the large scale pattern
supports severe storm outbreaks. Details are always the tricky part,
especially where individual upper waves track and how far east the
greater instability will be. There does remain some uncertainty with
exactly how amplified the large scale pattern will be and this will
influence those details.

&&

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 632 PM CDT Tue Jun 23 2026

Scattered showers and thunderstorms continue this evening,
mainly across the northern Red River Valley and northwest
Minnesota. KTVF and KBJI have the better chances to see
thunderstorm activity, thus a continuation of PROB30 into late
this evening. Outside of thunderstorms, VFR to MVFR ceilings
prevail into the early overnight period. Lower ceilings are
still expected across a large portion of the area heading into
Wednesday morning, with MVFR CIGs possible at all sites.

...FUNNEL CLOUD POTENTIAL ACROSS FAR NORTHEAST NORTH DAKOTA AND
NORTHERN RED RIVER VALLEY...

Showers and thunderstorms have developed across
far northeast North Dakota and the northern Red River Valley.
Conditions are favorable for funnel clouds with any thunderstorm
that develops within this area. These types of funnel clouds are
usually short lived, however, they can and occasionally do touch
the ground and cause minor damage. Therefore, if you see a funnel
cloud, take cover immediately.

South of this area, conditions are favorable for stronger storms.
