What forecasters said that day

The local office's own words before this winter storm 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 winter storm warning went out at Apr 12, 2:25 AM MDT, 16 minutes earlier.

Area forecast discussion, Apr 12, 2:25 AM MDT, 16 minutes before
Area Forecast Discussion
National Weather Service Bismarck ND
325 AM CDT Thu Apr 12 2018

.SHORT TERM...(Today and tonight)
Issued at 325 AM CDT Thu Apr 12 2018

Highlights include the issuance of a Winter Storm Warning
southwest, and a Winter Weather Advisory portions of western and
far south central North Dakota, all beginning this evening.

For the near term early this morning, fog/stratus loop and surface
observations show dense fog from Linton to McClusky, and from
Edgeley to Steele. Will continue with the dense fog advisory
through mid morning. A larger area of clouds is quickly
approaching and filling in across southwest and our far south
central counties. This may help to erode some of the dense fog as
it did earlier at Bismarck and Hazen.

Latest water vapor imagery indicative of a mid/upper level
shortwave in southern Idaho ejecting northeast with time. This
shortwave reaches southeastern Montana late this afternoon,
morphing into a closed low tonight, then shifting southeast into
southern South Dakota by 12z Friday. In doing so, synoptic scale
ascent peaks tonight into through Friday morning for most of
western and south central North Dakota. Snow will taper off and
end from north to south Friday afternoon. Total snowfall of
between 6 and 8 inches within the winter storm warning area of
southwest North Dakota; and between 3 and 6 inches within the
winter weather advisory for portions of western and far south
central North Dakota. Outside of the winter weather advisory area,
expect 1 to 3 inches which would include the rest of south
central and the southern James River Valley. No snowfall expected
for locations along and north of Highway 2.

.LONG TERM...(Friday through Wednesday)
Issued at 325 AM CDT Thu Apr 12 2018

Snow will taper off after 18z as the whole area shifts quickly to
the south and will end by 00z Saturday. Upper level ridging
approaches and slides through western/central North Dakota Sunday
night and Monday. Expect dry weather Saturday through Monday;
however a weak shortwave is forecast ahead of the approaching
ridge Saturday, yielding slight chances for rain or snow in the
far northwest. Next shortwave trough pushes through Tuesday/Tuesday
night. Will need to monitor for thunderstorm potential with this
given the GFS has weak CAPE all around our CWA. Dry on Wednesday
at this time.

&&

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 325 AM CDT Thu Apr 12 2018

Stratus, fog, and eventually more rain/snow highlights this taf
period. Cigs/vsbys will remain degraded between VLIFR and IFR this
taf period, but remaining dry through 21z Thursday. Thereafter,
increasing threat for rain/snow changing to all snow after 00z
Friday for KDIK/KBIS. Snow will become heavy at times at KDIK
toward the end of this taf period and through Friday morning.
