.DISCUSSION...
Issued at 108 AM CDT Sat Apr 4 2026

As of 1 AM CDT, snow continues to fall across north central and
northeast SD. Temperatures are in the mid 20s to about 30. Winds are
out of the north at about 10 mph.

Snow is expected to continue across central and northeast SD through
the morning, coming to an end west to east through the late morning
and into the afternoon hours. The previous run of the NBM was
running a little behind, leaving snow chances in north central SD
several hours longer than high-res guidance. The newest run, though,
looks to have caught back up. QPF has come down quite a bit, most
noticeable along the ND/SD border. With this, additional snow
accumulations have also decreased. The chance of an additional 2
inches is between 30 and 50% west of the MO river and about 50-70%
between the MO and the James. The chance of an additional 4 inches
is between 60 and 90% east of the James River and north of Hwy 12.
Winds are expected to pick up as we move towards sunrise, and then
strengthen to 25-35 mph this afternoon, mainly east of the MO River.
Since the snow already on the ground is quite wet, as is the snow
forecast to fall this afternoon across north central SD, blowing
snow is still not expected to cause too much in the way of reduced
visibilities. However, in places with significant ice accumulations,
power outages due to strong winds blowing ice covered power lines
will be possible.

Temperatures through the first half of next week are still expected
to be below average by as much as 15-20 degrees. Models are showing
a brief warm up Wednesday ahead of a cold front that will bring
slightly cooler air to the region as a low moves across southern
Canada. Another low coming up from the southeast will bring a chance
for some rain and potentially some light snow for the end of the
week. At the moment, snow accumulations are expected to be light as
the dominant precip type is expected to be rain. Some snow could mix
in during the overnight hours when temperatures drop below freezing.
Will keep an eye on this over the next several days.
