Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
1019 AM MST Tue Feb 9 2021

.DISCUSSION...(Today Through Monday)
Issued at 129 AM MST Tue Feb 9 2021

Persistent upper trough sits over the CONUS, as the upper low
spins over central Canada. Skies across the region are mostly
cloudy, and radar/web cams are showing some light snow/flurries
over much of the CWA. At the surface, high pressure continues to
stretch across MT and the Dakotas, resulting in light winds and
cold air over the region. Temperatures are below zero, and wind
chills are in the teens, 20s, and 30s below zero.

Cold, snowy weather will continue for the next several days, to
varying degrees. Expecting some clearing today and a brief break in
light snow. However, flurries will return this afternoon, along with
low clouds, and potentially some fog over the eastern foothills as
winds become easterly. Chances for light snow will increase tonight
as a weak shortwave crosses the region, with light snow/flurries
continuing into Wednesday. Accumulations will be minimal. Highs both
days will be mainly in the single digits, with lows in the single
digits and teens below zero.

As the Canadian low swings into the northern states later this week,
more snow and even colder air will be pulled into the region behind
a shortwave and its associated cold front. Highs Thursday and
especially Fri/Sat will struggle to rise above zero. With overnight
lows in the teens and 20s below zero, wind chills will be in the 30s
to 40s below zero. Anticipating further wind chill headlines will be
issued through the week. Snow totals for the late week system are
looking like generally 1-3 inches, with some locally higher amounts
possible, especially across the south.

Ensembles agree that warmer air will arrive next week. However,
temperature spread of the ECMWF ensemble, for example, increases to
almost 50 degrees by Sunday, so confidence is low on exactly when
the warmer air will arrive.

.AVIATION...(For the 18Z TAFS Through 18Z Wednesday)
Issued At 1017 AM MST Tue Feb 9 2021

Mainly VFR conditions are expected this afternoon with local MVFR
conditions near the Black Hills into far southern SD. A weak
disturbance will bring easterly upslope flow to the area tonight
with patchy light snow/flurries. MVFR CIGS will develop tonight
and persist into Wednesday. IFR/LIFR conditions will occur in/near
the Black Hills due to low clouds/patchy light snow/fog.
