What forecasters said that day

The local office's own words before this wind chill warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Rapid City, SD wrote its last area forecast discussion before this wind chill warning went out at Feb 11, 11:34 AM MST, 2 hours 16 minutes earlier.

Area forecast discussion, Feb 11, 11:34 AM MST, 2 hours 16 minutes before
Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
1134 AM MST Thu Feb 11 2021

.DISCUSSION...(Today Through Wednesday)
Issued at 239 AM MST Thu Feb 11 2021

Upper level analysis and water vapor imagery depict broad, cyclonic
flow across the northern half of the United States. A quick moving
wave is currently pushing through the Northern and Central Plains
along the southern periphery of a deep upper low centered over
central Canada. At the surface, high pressure is situated to
our northwest across northern MT/southern Alberta with arctic
air firmly entrenched over the area.

Light snow continues across much of the forecast area this morning
and will continue throughout the day, especially across the southern
half of the forecast area. Broad large-scale forcing for ascent will
persist through the day today as a jet streak noses into the region
atop the mid-level baroclinic zone. The passage of another quick
moving wave Friday will result in an uptick in snow potential across
the southern half of the forecast area. The prolonged light snow
coupled with high snow ratios will result in a few inches of snow
for areas along and south of I-90 today through Saturday morning.
Areas along the SD/NE border and the central and southern Black
Hills could see locally heavier snow of 2-5 inches by Saturday
morning. At this point, have opted to hold off on a Winter Weather
Advisory given the prolonged nature of the event for the southern
counties. If, however, it appears that snowfall is expected to be
heavier an advisory may be needed.

Beyond the snow, very cold temperatures will continue through at
least the weekend. An additional surge of arctic air is expected to
slide southward later tonight into Friday. The resulting low
temperatures will fall well below zero across the entire area
with highs struggling to push above zero through Sunday.
Dangerously cold wind chills will continue during the overnight
and early morning hours through Monday; some areas are likely to
see wind chills as cold as 40 below at times this weekend,
especially across NE WY and NW SD. Will likely have to upgrade
portions of the Wind Chill Advisory to a Warning, especially for
NW SD, as this arctic surge continues into the weekend.

Deterministic and ensemble guidance are trending toward temperatures
moderating closer to average for by mid-week next week along with
drier conditions. Confidence is high that we will see much warmer
air, relatively speaking, by next week, although ensemble spreads
are still quite high (40-50 degrees). Lingering snow cover and its
impact on temperatures coupled with the large temperature spread
makes pinning down exact temperatures difficult, although the
trend is toward more normal temps to end next week.
