The radar

The Fargo/Grand Forks radar (KMVX), 117 km from the middle of the area, began a volume at 22:34 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.

The nearest sounding before it

International Fa, MN (KINL), launched 12:00Z, 10.5 hours before the alert went out and 292 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.

.KEY MESSAGES...

- Isolated to scattered t-storms today until sunset over the
  area. There is a 1 out of 5 risk of brief severe storms in
  southeastern North Dakota and west central Minnesota. But any
  storm is capable of heavy rain, lightning, and small hail.

.DISCUSSION...
Issued at 240 PM CDT Sat Jul 4 2026

...Synopsis...

Near zonal flow aloft over the Northern Plains, with a good
shortwave over the southern Red River currently providing some
lift for storms developing in west central Minnesota. The weak
frontal boundary/wind shift draped across that same area will
start to wash out tonight as lee troughing gets going to our
west. South to southeasterly winds will continue into Sunday as
upper ridging builds into the Plains and upper midwest. A
shortwave riding over the top of the ridge through southern
Canada will help push a front back south into ND by Monday. A
stronger shortwave comes through the Dakotas on Tuesday, pushing
the frontal boundary down into our southern counties.
Northwesterly flow aloft west up for mid to late week, with
several of the model solutions showing an embedded shortwave
coming through on Friday.

...Thunderstorm chances this afternoon and early evening...

Most of the development so far has been in west central MN ahead
of the shortwave, and with good heating boosting ML CAPE to over
2000 J/kg, several of the cells have gained enough height to
produce some 1 inch hail even with negligible shear. Any severe
threat from a individual cell will be short lived as they come
up and then right back down. Some localized street flooding is a
possibility with slow movement of storms and PWAT values over
1.5 inches. Further north and west, there is less instability
and deep moisture convergence is less impressive, and shear is
not any better. Could see some lightning and brief downpours,
maybe even some pea sized hail from any isolated cells that
develop this afternoon. A few of the CAMs show storms
redeveloping over the southern Red River Valley around 00Z, with
HREF showing around a 40 percent chance for some lightning. Not
a slam dunk but will have to keep an eye on general
thunderstorms for a while. By sunset, most of our instability will
be on a downward trend and the main shortwave will be pushing
east. HREF probabilities of thunder are on a rapid downward
trend after 03Z, but may have to watch a few spots at fireworks
time for any lingering convection.

...Severe chances Sunday night and again Monday...

The shortwave coming over the top of the upper ridge late Sunday
could bring some storms to north central ND that could clip our
far northwestern counties. HREF updraft helicity probabilities
are not too impressive with only a few members showing any
paintballs in Towner county, but can't rule out a few isolated
cells. Better, but still marginal chances for severe storms will
be Monday as the frontal boundary sags south into our area.
Ensemble mean CAPE according to the NBM gets over 2000 J/kg by
Monday afternoon and deep layer shear increases to 35 to 40 kts.
Still a few days away, but if the trends that the NBM shows hold
Monday looks like a fairly busy convective day.

&&

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1242 PM CDT Sat Jul 4 2026

VFR conditions at most of the TAF sites, except KBJI which is
being impacted by thunderstorms and vis has dropped down to MVFR
for a time. Convection will continue to redevelop around KBJI
through the afternoon, and could stray as far west as KTVF or
KFAR, but less certain for those spots so will keep any CB
mention out for now. Convection at KBJI will taper off around
sunset, with all sites VFR. Light and variable winds for most of
the TAF sites will begin to pick up out of the southeast by
tomorrow morning at KDVL, but speeds should remain below 10
kts.

...FUNNEL CLOUDS POSSIBLE ACROSS PARTS OF NORTHWEST MINNESOTA...

Showers and thunderstorms have developed across
parts of northwest Minnesota and are interacting with a weak
frontal zone stretching from eastern Marshall County to western
Otter Tail County. This is resulting in conditions favorable for
funnel clouds with any thunderstorm that develop. These types of
funnel clouds are usually short lived, however, they can
occasionally touch the ground and cause minor damage. Therefore,
if you see a funnel cloud, take cover immediately.
