.DISCUSSION...
Issued at 100 AM CDT Mon Apr 6 2026

As of 1 AM CDT, temperatures around the area are in the 30s with
winds out of the northwest between 10 and 15 mph. Some light snow
showers will move into central SD this morning. There is the
potential for this to end up as rain if temperatures don`t cool as
much as expected. Little to no accumulation out of this. If anything
does accumulate it will melt quickly.

We`re under a pretty cool airmass today which will keep our highs 15
to 20 degrees below normal for this time of year. Fortunately, high
pressure moves in later today and brings our winds around to out of
the south. This will bring much warmer air up into the region and
bring temperatures up to around normal by Wednesday. Tuesday and
Wednesday will be a bit windy with gusts of 30 to 45 mph ahead of
and behind a low pressure system. The strongest winds, gusting near
45 mph, will be Wednesday across north central SD. This system will
also bring a 30-60% chance of rain to the region, highest across
northern SD late Tuesday night into early Wednesday morning. The
chance of more than a tenth of an inch in 24 hours is still 15% or
less. This event does look to stay predominantly rain, but there is
a chance some snow could mix in for an hour or two in the Missouri
River valley overnight Tuesday. We get a little bit of a break
Thursday before 30-40% chances return and remain in place through
the weekend. The period of heaviest rainfall looks to be Sunday
night into Monday morning. The chance for more than a quarter of an
inch in 24 hours (ending Monday morning) is between 30 and 50%,
highest over eastern SD. Temperatures for the weekend look to be
about 10 to 15 degrees above average.
