Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
1022 PM MST Fri Dec 29 2017
.DISCUSSION...(This Evening Through Friday)
Issued at 209 PM MST Fri Dec 29 2017
Broad cyclonic flow continues across much of the CONUS as very cold
air sits across the northern Plains into the Great Lakes region and
Northeast. Northwest flow aloft persists across the region, with a
series of weak waves pushing through. Surface analysis shows arctic
high pressure across Alberta sliding southeast toward the Dakotas.
Temperatures have been steady or falling across the CWA. KUDX radar
has been showing snowfall persisting through the day across the
southern Black Hills. Snow has been increasing over the last hours
across the northern Black Hills and adjacent plains. Models show
leeside convergence enhancing the snowfall through the rest of the
afternoon across the southeastern to eastern portions of the Black
Hills and foothills. With snow already falling across portions of
the Hills, will move up to the start time of the Winter Weather
Advisory to when the afternoon package is issued. Rest of the
headlines are in good shape at this point. Snow will increase in
coverage this evening and continue through Saturday afternoon. The
best snowfall rates are expected to be tomorrow late morning into
the afternoon as a strong upper waves pushes through the Dakotas.
Additional snowfall amounts ranging from 2 to 6 inches are expected
across much of northeast Wyoming and western South Dakota. Behind
the departing wave, dry weather will move into the region and
continue through much of next week. Very cold temperatures are also
expected through Monday. Sunday is still expected to be the coldest
day, with highs ranging from 5 above to 10 below. The coldest night
for most locations will be Monday morning, with lows ranging from 10
below to 30 below zero. Wind chills that morning could range from 20
below to 45 below zero. Will have to continue to monitor for
possible future headlines. Much warmer air will advect in by Tuesday
with highs much closer to seasonal averages but still slightly
below. These temps will generally continue through much of next
week.

.AVIATION...(For the 06Z TAFS Through 06Z Saturday Night)
Issued At 1022 PM MST Fri Dec 29 2017
Primary band of snow has set up to the north of our TAF sites this
evening. Within this band, roughly oriented from southeast Montana
to just north of PHP, IFR/LIFR VSBYS are likely. Short-term model
guidance is handling placement of this band fairly well but has it
a bit too broad in north-south extent. For now, will go with radar
trends and keep snow and associated lower CIGS/VSBYS north of
RAP/GCC through the overnight.
However, as winds become easterly late overnight at RAP, upslope
flow will likely produce IFR CIGS and potentially some light snow
or freezing fog. For now, have left any weather out of the TAF
until tomorrow morning. Widespread MVFR/IFR conditions are
anticipated Saturday as snow chances increase again area-wide.
