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 Jun 14, 6:42 PM CDT, 1 hour 17 minutes earlier.

Area forecast discussion, Jun 14, 6:42 PM CDT, 1 hour 17 minutes before

Area Forecast Discussion
National Weather Service Bismarck ND
642 PM CDT Sun Jun 14 2020

.MESOSCALE DISCUSSION...
Issued at 641 PM CDT Sun Jun 14 2020

At 515 PM MDT, a long-lived supercell was moving northeast across
northwest Adams County. This storm has a history of golf ball size
hail and severe wind gusts to at least 66 mph. Despite model
hodographs continuing to suggest a slightly left-moving dominant
mode, this supercell has been a right-mover since its inception,
with occasional splits that have seen the left-mover quickly fizzle.
Immediately to the north of the supercell, convective development
has become rather robust within the last half hour. We are likely
witnessing the beginning of the transition from a discrete to linear
mode. The large hail threat will be diminishing over the next two
hours, with damaging wind becoming the more prominent severe threat.

Farther north, a supercell that originally was part of a multicell
cluster in Golden Valley County has been able to emerge and eject
off the surface boundary. Large hail will be the main threat as
long as the storm remains isolated.

While the overall tornado threat remains low, it will be relatively
maximized over the next 1-2 hours as storms enter an environment
with lower LCL heights and directional low level wind shear.

&&

.UPDATE...
Issued at 611 PM CDT Sun Jun 14 2020

Increased precipitation chances south and decreased north. A
cluster of storms continues to develop across southwest North
Dakota. These storms will continue to push eastward northeast as a
cold front swings through. Latest indications are the strongest
storms should stay across the southern half of North Dakota
tonight.

UPDATE Issued at 324 PM CDT Sun Jun 14 2020

This update is for the severe thunderstorm watch 281 for west and
much of central North Dakota through 11 pm CDT.

&&

.SHORT TERM...(This evening through Monday)
Issued at 211 PM CDT Sun Jun 14 2020

This afternoon, a surface trough/cold front was located on the
Montana/North Dakota border. Scattered showers have moved through
the west half of the state so far today, and these appear
associated with warm advection ahead of the low. The area in
central North Dakota still remains well capped. Also clouds have
kept temperatures cool across much of the west so far.

Several strong cells have formed in west central North Dakota in
an area of weak cap strength and clearing skies. CAM models
agree in developing a line of storms along the cold front that
will move east into central North Dakota by mid evening.

Scattered severe storms are forecast along the front, probably
around and after 4 pm CDT. Initial storm mode will be discrete
with large hail as the shear will be more perpendicular to the
frontal boundary, but more linear modes will lead to a mixed hail
and wind threat evolving as the mid evening hours approach.

After this evening, the overnight will see the front move through
with cooler and drier air expected. Overnight lows tonight in the
lower 50s west to around 70 east.

Monday will be partly to mostly sunny with surface high pressure
moving through the region. Highs should be in the mid 70s to mid
80s.

.LONG TERM...(Monday night through Sunday)
Issued at 211 PM CDT Sun Jun 14 2020

Global models in general agreement with h5 upper low across the
northwest CONUS moving east with multiple shortwaves impacting
the northern plains this week. This will lead to an active week
with scattered to numerous showers and thunderstorms through the
period.

Tuesday will be warm, with highs in the low to mid 90s, cooling to
the 70s and mid 80s the rest of the week.

&&

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 611 PM CDT Sun Jun 14 2020

Hazards to aviation include a cluster of thunderstorms currently
in southwestern North Dakota and wind shear across the James
River Valley. Thunderstorms will impact KDIK and KBIS within the
next couple of hours this evening and could potentially impact
KMOT. Erratic and strong winds and large hail may accompany any
storms. LLWS is likely at KJMS most of the night. Otherwise VFR
conditions.
