What forecasters said that day

The local office's own words before this high wind watch 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 high wind watch went out at Mar 27, 2:22 AM MDT, 2 minutes earlier.

Area forecast discussion, Mar 27, 2:22 AM MDT, 2 minutes before
Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
222 AM MDT Sat Mar 27 2021

.DISCUSSION...(Today Through Friday)
Issued at 221 AM MDT Sat Mar 27 2021

Departing upper trough and cyclonic flow will continue to support
slightly unsettled conds today, with one more round of showers.
Shortwave upper ridge will then quickly build east and support
warm and dry weather Sunday and part of Monday, with windy
weather. Impulse rotating through the flow is supporting a band of
rain/snow showers across the SE third. Another area of
lift/instability will rotate into the FA later this morning and
support another round of sct/isold showers into this afternoon.
Drying BL will certainly limit coverage on the plains, with the
best chance for precip over the Black Hills per elevation. Drying
and clearing will commence tonight as a weak sfc ridge slides
east. Upper ridge will shift east Sunday with broad Rockies
downslope westerly flow supporting strong heating ahead of a
digging NW CONUS upper trough. Strong mixing both Sunday and
Monday will support deep mixing and resultant warm temps (more so
toward central SD Monday). However, a potent northern stream upper
trough will quickly dig into the northern Plains by Monday.
Forecast models continue to offer a faster arrival of the cold
front Monday, supporting a fast exit of the thermal ridge. Hence,
sig cooler temps are favored over the NW half as the sfc front is
expected to clear a large portion of the FA Monday morning. Would
not be surprised to see the front arrive even earlier in future
model runs given the strength of CAA/pressure rises, with highs
reached in the morning over the NW half. Before the front arrives,
strong LL SW flow will ensue ahead of the sfc front. Expected
flow combined with terrain effects from the Black Hills will
likely support a standing mountain wave with associated downslope
winds Sunday night into Monday morning. Forecast models, esp the
ECMWF and NAM indicated the potential for gusts over 60 mph in the
eastern portion of the SD Black Hills into the adjacent
foothills. Hence, given this persistent model signal, opted for a
high wind watch Sunday night into Monday morning there. Strong NW
winds can then be expected with the cold front with adv to
potentially warning level winds possible Monday, esp over NW SD
and in the lee of the Black Hills. As the upper trough and
associated jet streak begin to push into the western FA Monday,
expect increasing chances for showers in the west, mainly confined
to NE WY. Cooler temps are expected mid week, with another sig
warm up toward the end of the week as another large upper ridge
pushes east. Dry conds will prevail in this period.

&&

.AVIATION...(For the 06Z TAFS Through 06Z Saturday Night)
Issued At 941 PM MDT Fri Mar 26 2021

MVFR conditions (with some IFR over the Black Hills) will continue
overnight in rain/snow showers and patchy fog. Conditions will
improve from west to east overnight. Mainly VFR conditions are
then expected through Saturday evening, except some brief MVFR
conditions in showers that develop, especially Saturday afternoon.
Northwesterly winds will become breezy Saturday, and gusty near
showers.

&&

.FIRE WEATHER...
Issued At 221 AM MDT Sat Mar 27 2021

Warm temps with gusty westerly winds and low relative humidity
look to support critical to near critical fire weather conds
Sunday and Monday across much of the area, especially northwest
SD. Given drier and breezier progs, have added a portion of
northeast WY to the fire weather watch for Sunday. Otherwise,
forecast models continue to trend toward a quicker arrival of the
cold front Monday, which looks to limit critical fire weather
conds toward central SD. With very dry air and strong winds behind
the cold front, combined with lingering uncertainty, will leave
the watch as is for SD.
