AREA FORECAST DISCUSSION
National Weather Service Sioux Falls SD
1211 PM CST Thu Jan 14 2021

.SHORT TERM...(Today through Saturday Afternoon)
Issued at 409 AM CST Thu Jan 14 2021

Early morning GOES imagery shows the initial wave has plowed through
the area, with wind gusts largely in the 20-40 mph range. Behind the
stronger lift that the initial wave had, positive vorticity advection
associated with the upper level trough swinging through will keep
chances for a rain/snow mix going through the morning hours, before
it switches over to all snow later in the morning. There could very
well be a couple hours where no snow is falling, especially for
locations west of the I-29 corridor.

As for the wind, wind speeds at the top of the mixed layer exceed 50
knots for most locations by mid-late morning, with some even getting
over 60 knots. The mixy boundary layer will allow for some of those
higher winds to be mixed down, so the High Wind Warning seems to be
in good shape as wind gusts will likely exceed 60 mph.

As the upper level low starts to wobble over southern MN and
northern IA, expect snow to start moving in from the east traveling
westward. Sounding profiles suggest the DGZ becomes saturated by
late afternoon or early evening, which suggests this is when the
heavier snow period will begin. It is during this same period that
the surface low strengthens which tightens the surface pressure
gradient over our area, leading to strong wind conditions throughout
the overnight period with gusts again approaching 60 mph. The strong
winds will likely not allow for the big dendritic flakes we would
normally expect, so this will likely have an effect on the storm
total snowfall.

Due to the combination of moderate to heavy snowfall with such
strong winds, have upgraded the Winter Storm Watch to a blizzard
warning for all counties. Expect very difficult, if not impossible
travel conditions during the evening and overnight hours. If you
must travel...have a winter survival kit with you.

The trowal will likely be over the area by mid morning, which will
continue periods of moderate to heavy snowfall for a couple more
hours. By late morning, areas west of the I-29 corridor will begin
to see snowfall end as the system wraps up and the trough begins to
lift towards the east coast. Unfortunately, while the winds will
begin to slowly decrease, they will remain strong enough to blow
around the recently fallen snow, continuing the blizzard conditions.
Conditions should begin to improve by late Friday evening, as wind
speeds continue to decrease into the overnight hours.

.LONG TERM...(Saturday through Wednesday)
Issued at 409 AM CST Thu Jan 14 2021

As we transition out of the trough now well off to our east, another
shortwave begins to move towards the area leaving us underneath
northwesterly flow aloft. This will lead to a rather uneventful day
weather-wise, with wind gusts on the calm end under 20 mph.
Temperatures also don't look to be getting drastically cold, with
seasonal highs in the mid 20s for most, getting closer to mid 30s
for areas along the MO River in central SD. The shortwave passing
over on Sunday could lead to a few flurries in SW MN and NW IA, but
most models agree nothing measurable should occur.

Could have another weak system slide towards us on late Monday into
Tuesday as we transition back towards northwesterly flow aloft, but
not looking to be an impactful snowfall. The flow aloft looks to
flatten over the area by mid-week as a stubborn upper level low
develops over southern California. Temperatures will remain
seasonal, or even slightly above normal for mid January.
