What forecasters said that day

The local office's own words before this wind advisory 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 advisory went out at May 24, 11:35 AM MDT, 1 hour 56 minutes earlier.

Area forecast discussion, May 24, 11:35 AM MDT, 1 hour 56 minutes before

Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
1135 AM MDT Mon May 24 2021

.DISCUSSION...(Today Through Sunday)
Issued at 233 AM MDT Mon May 24 2021

08z surface analysis had low pressure over northwest ND with
trough into central WY. Drier air continues to infiltrate the CWA
on westerly low level flow. Water vapour depicted upper low over
southern AB with 110kt jet streak across the western Dakotas.
Quiet weather for the start of the week.

Today/Tuesday, upper low moves across far southern Canada and
weakens as shortwave ridge builds into the northern Rockies ahead
of upper trough moving into the northwest CONUS. Modestly tight
pressure gradient will promote breezy/windy conditions through
Tuesday, especially during the afternoon hours when low level
lapse rates steepest. There is some hint that popcorny isolated
shra/ts could develop during peak heating this afternoon and
Tuesday afternoon given cyclonic flow aloft/steep lapse rates.
Will keep forecast dry for now per consensus. Temperatures will be
near guidance.

Wednesday/Thursday, upper trough becomes upper low as it moves from
the northern Rockies into the northern Plains. Cyclogenesis occurs
over WY Wednesday with robust return flow/moisture advection into
northeast WY/western SD. At least moderate MLCAPE/shear expected
Wednesday afternoon/evening over the southern half of the CWA. Cap
should erode allowing scattered TSRA to develop, some of which
may bring large hail/damaging winds. Some disagreement with how
far north instability makes it Wednesday as well as the
possibility of stratus development given upslope component to
boundary layer flow. TS Wednesday night should become mostly SHRA
on Thursday bringing beneficial QPF. Temperatures near guidance in
the south and below guidance in the south.

Fast moving shortwave ridge brings quiet weather for Friday, but
another upper trough moves through for the weekend with additional
PoPs and seasonal temperatures.

&&

.AVIATION...(For the 18Z TAFS Through 18Z Tuesday)
Issued At 1132 AM MDT Mon May 24 2021

VFR conditions are expected through the TAF period. Breezy
southwest winds have developed across much of northeastern WY and
western SD and will persist through the afternoon. Occasional
gusts over 35 kt are expected. Gusts and sustained winds will
decrease after 00z, and particularly after 03z. Winds will switch
over to northwesterly Tuesday with gusty winds beginning after
14-16Z Tuesday morning.
