The radar

The Bismarck radar (KBIS), 104 km from the middle of the area, began a volume at 00:18 UTC, the scan nearest the moment this went out.

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.

What forecasters said that day

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

NWS Bismarck, ND wrote its last area forecast discussion before this severe thunderstorm warning went out at May 12, 6:06 PM CDT, 1 hour 8 minutes earlier.

Area forecast discussion, May 12, 6:06 PM CDT, 1 hour 8 minutes before

Area Forecast Discussion
National Weather Service Bismarck ND
606 PM CDT Thu May 12 2022

.UPDATE...
Issued at 606 PM CDT Thu May 12 2022

Extrapolating forward motion of the well-organized, intense, and
long-lived line of storms in northeastern SD as of 23 UTC takes
it across southeastern ND through about 03 UTC. Low-level static
stability increases with northward extent, especially toward the
I-94 corridor, but strong low-level mass-field responses suggest
a higher than normal uncertainty in PBL-based thermodynamic fields
in model guidance and objective mesoscale analysis data. This
does yield some uncertainty to tornado risk with northward extent,
but intense low-level shear and the non-zero risk for PBL-based
CIN to be minimized over the James River valley means the threat
of tornadoes certainly exists. Moreover, even if convection tends
toward a more elevated state, DCAPE around 1000 J/kg and intense
0-3-km bulk shear on the order of 40+ kt will continue the risk of
severe winds into ND. Further northwest across central ND, storms
are elevated at a much higher altitude owing to cooling aloft and
a deepening moist layer since our 19 UTC special sounding, but
strong shear and modest MUCAPE support a continued large hail risk
with the more intense updrafts.

Otherwise, for this update we have only blended to observed trends
into the evening. We are maintaining the high wind headlines as-is
at this point, though signals are increasingly suggestive that the
remainder of the High Wind Watch will need to be upgraded to a
warning at some point this evening.

&&

.SHORT TERM...(This evening through Friday)
Issued at 224 PM CDT Thu May 12 2022

Current surface analysis places low lifting through south central
South Dakota, with warm front stretching to the east. Upper level
analysis places negatively tilted trough over the western CONUS,
with the base attempting to close off over Colorado. Strong south
to southwesterly flow remains over our area. Over our neck of the
woods, showers with a few embedded thunderstorms have been on the
increase over the past few hours in response to the approaching
systems. With plenty of low level moisture in place, a lingering
area of fog has developed over southwest North Dakota. With all
that said, the main show lies ahead.

For the rest of this afternoon into tonight, low and warm front
continue their northerly lift. Robust convection is expected to
develop over north central into eastern South Dakota, possibly
into far south central and southeast North Dakota late this
afternoon into the early evening. This area has continued to show
very strong deep layer shear (well in excess of 50 kts), elevated
low level shear, and strong instability in excess of 2.5 kJ/kg. As
mentioned for the past few days, all sorts of severe weather
remain in play (large hail, wind, a few tornadoes). As for the
heavy rain threat, the storms may have heavy rainfall rates, but
the good news is that the storms should be quick moving, and not
loitering over an area too long. For our area, focus for the
greatest chances for severe weather remain over the southern James
River Valley, with lesser chances over south central North Dakota
into the upper James River Valley.

As we go through the evening into the overnight, winds will be on
the increase as the low gradually lifts north the area and
deepens, starting to stack up with the upper features. Tight
pressure gradient develops with winds becoming strong, starting
in the southwest and spreading northeast overnight. Feeling quite
confident in strong winds over the southwest, and marginally
confident elsewhere. Therefore, have issued a warning southwest,
watch elsewhere.

On Friday, winds continue through they day, tapering off on the
evening. With the cyclonic flow in places, expect a few showers to
develop, which will taper off in the evening/overnight.

.LONG TERM...(Saturday through Thursday)
Issued at 224 PM CDT Thu May 12 2022

Quiet weather though occasionally windy expected through the
weekend into the beginning of the work week. Active weather
pattern shows up towards mid-week bringing returning rain shower
chances.

&&

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 606 PM CDT Thu May 12 2022

Widespread IFR to LIFR conditions are expected tonight over most
of western and central ND along with widespread showers and storms
as a strong low pressure system impacts the region. Ceilings will
gradually improve from south to north Friday, but MVFR conditions
will likely persist in western and north central ND through Friday
daytime. East-northeast winds this evening will gradually shift to
the west late tonight and Friday morning, with west winds gusting
from 40 to 50 kt area-wide late tonight and Friday.
