The radar

The Minot AFB radar (KMBX), 115 km from the middle of the area, began a volume at 04:17 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.

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 22, 10:40 PM CDT, 36 minutes earlier.

Area forecast discussion, May 22, 10:40 PM CDT, 36 minutes before

AREA FORECAST DISCUSSION
National Weather Service Bismarck ND
1040 PM CDT SUN MAY 22 2016

.UPDATE...
Issued at 1040 PM CDT Sun May 22 2016

Quick update to cancel the western parts of severe thunderstorm
watch 192. The effective cold front, which has been partly re-
inforced by storm outflow, has moved east of a Minot to Fort
Yates line as of 0330 UTC. The severe threat has ended west of
the front. We are maintaining the watch east of there for now
given modest instability and moderate to strong deep-layer shear,
but radar trends suggest the severe threat is marginal.

UPDATE Issued at 859 PM CDT Sun May 22 2016

MODERATE INSTABILITY REMAINS OVER CENTRAL INTO EASTERN NORTH
DAKOTA ALONG WITH SUFFICIENT DEEP LAYER SHEAR TO RESULT IN A
CONTINUED SEVERE THREAT AHEAD OF A COLD FRONT DROPPING THROUGH
CENTRAL NORTH DAKOTA. STORMS HAVE HAD TROUBLE BECOMING VERY
STRONG...THOUGH HAVE HAD REPORTS OF PROLIFIC SMALLER HAIL
PRODUCING STORMS ALONG WITH HEAVIER RAIN PRODUCERS OVER THE JAMES
RIVER VALLEY REGION WHERE HIGHEST PRECIPITABLE WATER VALUES WERE
NOTED. SOME POST FRONTAL STORMS ALSO CONTINUE TO DEVELOP WHICH MAY
BE SPAWNED BY AN UPPER LEVEL JET STREAK LIFTING THROUGH THE
REGION. WILL KEEP CURRENT SEVERE WATCH IN TACT.

UPDATE Issued at 605 PM CDT Sun May 22 2016

Thunderstorms are starting to develop over western into south
central North Dakota. Stage is still set with increased
instability and sufficient deep layer shear to support severe
storms with large hail and damaging wind gusts as the main
threats. Plenty of moisture continues to surge in ahead of
gradually progressing cold front (dewpoints in the lower 60s) to
bring the risk of heavy rainfall from some storms. The area with
the greatest risk for this continues to be over south central
North Dakota into the James River Valley.

&&

.SHORT TERM...(This evening through Monday)
Issued at 206 PM CDT Sun May 22 2016

Severe thunderstorms highlight the short term period

The latest water vapor imagery shows a closed low circulating
over Alberta with a 100kt jet streak stretched out from northeast
Montana into central Wyoming. This jet streak nudges east into
western North Dakota this evening. This will provide large scale
ascent along a cold frontal boundary, now located from Portal to
Stanley, and south into Hettinger. Dewpoints in the west are in
the lower 40s while in central North Dakota moisture is higher
with dewpoints near 60F. The cold front will slowly move east
tonight, exiting the James River Valley between 09z-12z Monday.

Visible imagery showing stratus eroding which will initiate and
increase low level buoyancy and instability. The HRRR and NAM look
to have a good trend with convection initiation. The most intense
cells begin near Lemmon SD and develop within a corridor between
Dickinson and Bismarck, and narrowing but continuously developing
towards Minot from 4pm-7pm cdt. This consolidates into a line of
thunderstorms that slides into the James River Valley this
evening. Another area of severe and/or heavy rain develops in
south central ND between 7pm and midnight. This is forecast to
move northeast and expand into the James River Valley with heavy
rainfall late evening into the overnight period. Large hail,
damaging winds, and heavy rainfall continue as the main threats
late this afternoon through tonight. Flash flooding possible in
the southern James River Valley late this evening into the
overnight period. More stable air shifts from west to east tonight
ending the precipitation after midnight.

.LONG TERM...(Monday night through Sunday)
Issued at 206 PM CDT Sun May 22 2016

Broad trough over the western CONUS gradually works eastward towards
the plains through the middle and end of the upcoming week. This
will bring active cyclonic flow to the area, though models are
having quite a bit of trouble with timing out individual short waves
within the system. With that said, will keep chances for
precipitation going given the active pattern. Near to slightly above
average temperatures expected.

&&

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 1040 PM CDT Sun May 22 2016

Thunderstorms will gradually end from west to east tonight, but
are forecast to linger longest over the James River Valley. Local
IFR ceilings and visibilities with heavy rain and gusty winds are
expected with some storms. VFR conditions are expected on Monday
behind the cold front crossing the area tonight.
