.DISCUSSION...(This Evening Through Tuesday)
Issued at 102 PM MDT Tue Oct 6 2026

Latest satellite imagery shows clear skies over the area.
Conditions like this will continue for the next several days.

Temperatures will remain warmer than normal for early October
through the next couple of days. But we`ll really feel the warmth
on Friday and Saturday with highs likely reaching the 80s to low
90s again.

Then a pattern change later this weekend will swing temps in the
other direction. Highs on the Sunday will range from the 50s in NE
WY and NW SD to the upper 60s to low 70s in south-central SD.
Beyond that, highs generally in the 50s are expected. Overnight
lows will take a dip as well, going from the 40s and 50s to the
30s and 40s early next week.

As the weather pattern changes, precip chances will increase
beginning Saturday night, lasting into next week. And with the
much colder air from the north, snow is a possibility. That being
said, if snow does happen, it would most likely be at night and in
the higher elevations of the Black Hills. Maybe a few flakes mixed
in with the rain in the plains. So for now, expect mainly rain and
be pleasantly (or unpleasantly, depending on your opinion of
winter) surprised if you see snow.
