What forecasters said that day

The local office's own words before this blizzard 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 blizzard warning went out at Dec 29, 6:45 AM CST, 1 hour 34 minutes earlier.

Area forecast discussion, Dec 29, 6:45 AM CST, 1 hour 34 minutes before
Area Forecast Discussion
National Weather Service Bismarck ND
645 AM CST Sun Dec 29 2019

.UPDATE...
Issued at 644 AM CST Sun Dec 29 2019

We added areas of fog to the forecast in western ND through 18 UTC
with this update in respect to observational trends, which reveal
reduced visibilities where a low stratus deck is intersecting with
higher terrain. We've chosen to handle impacts of the fog with a
Special Weather Statement versus a Dense Fog Advisory since we're
not confident in spatiotemporal extent of lowest visibilities.

Otherwise, regional radar imagery suggests intensifying snow in
eastern ND in line with earlier expectations, and we still expect
this to spread westward into the James River valley through the
morning.

&&

.SHORT TERM...(Today and tonight)
Issued at 429 AM CST Sun Dec 29 2019

Confidence in the details of snowfall amounts has increased area-
wide with this forecast release, including along the western
gradient of snow in south central ND. We continue to expect
impacts from the winter storm today and tonight, and it remains
possible that some portions of the James River valley and adjacent
south central ND could still need to be upgraded to a Blizzard
Warning in the next 6 to 12 hours, though confidence in widespread
and prolonged blizzard conditions was not high enough to make any
adjustments to existing headlines as of this writing.

Surface low pressure is located in northwestern Iowa early this
morning with broad and notable 3-hour pressure falls to its north
centered across MN, indicative of broad warm air advection driving
ascent across the region and supportive of northward movement of
the low into southwestern MN today. The 00 UTC global model suite
and most recent ensembles agree well on QPF totals for the rest
of the event and ensemble plumes suggest that the predictability
horizon has been reached even at Bismarck, where even the mixed-
physics WPC superensemble guidance has fallen into agreement in
the most likely outcome being 2-4 inches of additional snowfall
within the Winter Weather Advisory area. This is largely because
the most recent ECMWF ensemble set -- which had favored a more
western extent of heavy snow for days -- shifted eastward such
that only two of the ~45 member WPC superensemble/PWPF guidance
model inputs exceed the 4 inch mark at Bismarck/Mandan today and
tonight. Note that forecast soundings from the 00 UTC NAM and GFS
continue to suggest midlevel drying developing across central ND
today, which would reduce snowfall production and could result in
it completely ceasing for a time. However, model soundings also
suggest saturation with respect to ice could be close enough for
continued production of light snow from Bismarck/Mandan to Harvey
through the day, and the 00 UTC ECMWF -- which matches overnight
radar trends well and which is lighter than its prior cycles --
suggests light snow could continue through the day. Thus, we
showed a reduction in PoPs from 100% this morning to 60% this
afternoon in the Winter Weather Advisory area, but chose to keep
them in the likely threshold at this juncture.

Meanwhile, ensemble and more recent RAP/HRRR guidance is also
closely clustered in the Winter Storm Warning area centered on
the Ashley, Steele, Carrington, Jamestown, LaMoure, and Ellendale
areas with an expectation of 8-12 inches of additional snowfall
today and tonight. Frontogenesis based near 850 mb resulted in an
enhancement of snowfall in eastern ND between 06 and 09 UTC, and
then a subtle decrease in intensity, but guidance suggests there
will be additional frontogenetical forcing upticks today. Even if
they are transient, strong QG-forcing for ascent driven by large-
scale synoptic vertical motion including broad warm air advection
will support enough QPF for heavy snow in those areas. A blend of
NBM and MOS-based wind guidance suggests sustained speeds near 30
kt at times today, and inspection of the Canadian blowing snow
model suggested blizzard criteria could be met, but the expected
snow density and surface temperatures suggest a bit stronger wind
speeds are required for widespread blizzard conditions. Recent RAP
forecast soundings at Ashley and Ellendale suggest gusts closer to
45 kt developing, and if that comes to fruition than an upgrade to
Blizzard Warning will be required. However, other guidance is not
quite as strong with winds, and HREF-based blizzard probabilities
which take into account visibility reductions from heavy falling
snow and forecast gusts from CAMs were less than 30%, too. Thus,
in collaboration with NWS Aberdeen and Grand Forks we have chosen
to hold off on upgrading to Blizzard Warnings for now, though we
will closely monitor trends and upgrade later if necessary.

By tonight, frontogenetical circulations are forecast to diminish
but broad ascent associated with continued warm air advection
aloft and a related TROWAL will cause light snow to linger. The
snow may actually move westward and be centered on the Bismarck
and Mandan area by tonight given the expected forcing mechanisms,
but amounts will be light by that point. The surface pressure
gradient will remain strong and thus areas of blowing snow will
continue.

.LONG TERM...(Monday through Saturday)
Issued at 429 AM CST Sun Dec 29 2019

On Monday, conditions will slowly improve during the day as the
stacked midlatitude cyclone slowly shifts into the Great Lakes.
However, lingering light snow and gusty winds could result in a
continuation of winter weather impacts in south central ND and the
James River valley, so later trends may dictate some extension in
time of winter weather headlines past their existing expiration at
12 UTC Monday.

Otherwise, the 00 UTC global models support a warming trend this
week with NBM-based highs still in the 30s to around 40 F across
western ND Tuesday through Friday. Low-predictability shortwave
trough passages could yield some light precipitation and gusty
winds at times, and given expected thermal profiles we may have
to contend with mixed-phase precipitation forecast challenges.
Finally, guidance including CIPS analogs suggest that the heights
will fall and temperatures will turn colder beginning next
weekend, with mean 850 mb temperatures from the 00 UTC GEFS at
Bismarck dropping from +3 C on New Years Day to -15 C on Saturday.

&&

.AVIATION...(For the 12Z TAFS through 12Z Monday morning)
Issued at 644 AM CST Sun Dec 29 2019

Snow and blowing snow in south central ND through the James River
valley will produce IFR to LIFR conditions today and tonight, with
the worst conditions at KJMS where wind gusts to 40 kt will cause
near blizzard conditions at times. Light snow will impact KBIS as
well, but western and north central ND will escape most if not
all of the precipitation. Even so, an area of IFR and LIFR stratus
and fog will impact the west this morning, with potential
improvement to MVFR ceilings this afternoon and tonight.
