.DISCUSSION...
Issued at 124 AM CDT Tue Aug 4 2026

There could be some light sprinkles early this morning over south
central SD lingering behind a cold front that pushed through last
night. Other than these sprinkles, high surface pressure will be
moving over SD today through Wednesday. This high pressure will help
to keep rain and storms chances out of central and northeastern SD
through Wednesday. The wildfire smoke that moved in yesterday has
been slowly pushed south by the northerly winds behind the cold
front. There might be some lingering light concentrations of smoke
at the surface early this morning which will be pushed south out of
central and northeastern SD during the morning. There will continue
to be some wildfire smoke aloft into Wednesday, which could create
some hazy skies at times.

The lingering colder air that was pushed into SD by the cold front
will continue to keep temperatures today 5 to 15 degrees colder than
normal for this time of the year. Highs across central and
northeastern SD and west central MN will be in the 70s with lows
tonight dropping into the 50s. While the minimum relative humidity
this afternoon gets down into the low to mid 20s over north central
SD, weaker winds only gusting up to 20 mph will help to keep the
fire weather concerns lower.

A somewhat flat upper-level ridge will be moving in over SD
Wednesday through the rest of the week. This ridge will help to push
a little bit warmer air into SD, causing temperatures to rise back
up to be around normal. Highs will rise into the 80s then the low
90s over central SD Wednesday into the weekend, with northeastern SD
in the upper 70s to 80s. Models hint at a couple of small upper-
level shortwaves that move over SD Thursday and onward. This could
cause a few surface boundaries to move over the state as well as the
next chance for some scattered showers. While the models hint that
Thursday night might see some rain, there is variation in the models
as to if any of this happens. These potential shortwaves and showers
will need to have an eye kept on them to see if models start to come
to an agreement over the next few days.
