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 Oct 21, 2:51 PM CDT, 11 minutes earlier.

Area forecast discussion, Oct 21, 2:51 PM CDT, 11 minutes before
Area Forecast Discussion
National Weather Service Bismarck ND
251 PM CDT Wed Oct 21 2020

.SHORT TERM...(This evening through Thursday)
Issued at 1243 PM CDT Wed Oct 21 2020

A winter storm will impact the northern Plains tonight through
Thursday evening. The southward trend in model runs continues
today with the greatest snowfall potential across south central
and southeast ND. As confidence grows in amounts and location, we
have decided to issue a Winter Weather Advisory for the I-94
corridor and southwest ND and a Winter Storm Warning for locations
south of I-94 across south central ND.

Ahead of the upcoming system, broad but weak low-level warm air
advection is producing some light snow across southwest ND. This
area of snow should produce an inch or less.

Tonight, a trough is expected to deepen over the Rockies and
progress east towards the northern Plains. As this trough enters
the northern Plains mid to upper-level ascent will increase. A
700mb frontogenesis band will strengthen with the arrival of
the upper-level jet streak. The 12 UTC model suite is consistent
in keeping the best frontogenetical forcing near the southern
North Dakota border through Thursday morning. This is well
supported by ensemble guidance as the 12Z EC/GFS/CMC mean
ensemble probabilities keep the highest QPF axis along the
southern border. The southern tier of counties (mainly east of
the Missouri River) look likely to see the greatest snowfall
totals with probability of exceeding 6 inches in the 40 to 70
percent range (highest probs across the southern portions of the
counties). Guidance has continued to push the brunt of the forcing
(and QPF) over to the South Dakota side. North of I-94 to Highway
2 between one and four inches of snow may fall. North of Highway 2
an inch or less is expected.

.LONG TERM...(Thursday night through Wednesday)
Issued at 1243 PM CDT Wed Oct 21 2020

Potentially record breaking cold temperatures are forecast this
weekend into early next week. Another system may bring
accumulating snow this weekend as well.

Snow tapers off Thursday evening as high pressure settles in
behind the trough. A seasonably cold 850mb air mass is expected to
accompany the cold surface high with NAEFS guidance showing both
850mb temperatures and MSLP near climatological minimum and
maximum respectively Friday into early next week. Forecast lows
drop into the teens and single digits with daily highs
consistently below freezing. Some locations across southwest ND
may even see below zero temperatures early next week.

Another round of snow will be possible Saturday as the next trough
crosses the region. The latest global model runs show a very
similar setup to tonight/tomorrow's system coming through
Saturday night into Sunday. While differences exist between
deterministic models in north-south placement, ensemble
probabilities increased with NBM producing higher end PoPs across
the south during this period.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1239 PM CDT Wed Oct 21 2020

Persistent IFR/MVFR stratus continues across portions of central
North Dakota. Models are struggling with detecting this which
makes timing out improvement to VFR challenging. Widespread
chances for snow begin between 00Z and 06Z and last through
Thursday. Areas in southern North Dakota may receive heavy snow
with IFR conditions, impacting KDIK-KBIS-KJMS.

&&

.BIS WATCHES/WARNINGS/ADVISORIES...
