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 Aug 18, 6:37 AM CDT, 23 minutes earlier.

Area forecast discussion, Aug 18, 6:37 AM CDT, 23 minutes before

Area Forecast Discussion
National Weather Service Bismarck ND
637 AM CDT THU AUG 18 2016

.UPDATE...
Issued at 631 AM CDT Thu Aug 18 2016

Thunderstorms continue to push through the James River Valley with
the strongest storm now located in Stutsman County. For early
morning update have adjusted precipitation chances towards the
current trend. Cold front now appears to be pushing its way well into
southern North Dakota. Updates have been sent.

&&

.SHORT TERM...(Today and tonight)
Issued at 315 AM CDT Thu Aug 18 2016

Early this Thursday morning a cold front stretched across North
Dakota just north of Interstate 94. Showers and thunderstorms are
expected to continue to fire along and north of the front this
morning as low level convergence remains strong and a potent low
level jet continues to feed moisture over the frontal boundary.

As the front tracks further south it will encounter increasingly
unstable air and more favorable shear. Therefore, thunderstorms
may intensify across southern North Dakota later this morning and
into the afternoon. Strong or even isolated severe storms aren't
out of the question this morning and afternoon across portions of
far southern North Dakota.

Cooler and drier air will move in from the northwest this morning
and bring an end to precipitation from northwest to southeast
through the day.

.LONG TERM...(Friday through Wednesday)
Issued at 315 AM CDT Thu Aug 18 2016

A deep Hudson Bay low is expected to bring a wave through central
Montana Thursday night which will bring showers and scattered
thunderstorms to southwest North Dakota Friday. As this feature
moves across the baroclinic zone left from the recent cold front
more abundant showers and thunderstorms will form but now mainly
along and south of the North Dakota border Friday.

Cooler and drier air will spread south into the region Friday and
Saturday. Highs will be in the 60s and lower 70s both days.
Additionally morning low temperatures will feel quite brisk with
readings in the 40s. This will be followed by a slow moderating
trend next week into the 70s and 80s. The chance for precipitation
will be low through next Tuesday when a slight chance of
thunderstorms arrives.

&&

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 631 AM CDT Thu Aug 18 2016

MVFR or IFR conditions will accompanying isolated to scattered
thunderstorms. Also, localized MVFR to IFR cigs will be possible
over far western North Dakota this morning in the wake of a
passing cold front. Otherwise, VFR conditions are expected.

&&

.BIS Watches/Warnings/Advisories...
NONE.
