Fall officially starts Sunday afternoon, and with it come thoughts of the first frost. While Wednesday's weather was far from a frost, we know that type of weather is just around the corner.
Here's a look at the average first 32 degree morning in KELOLAND. It occurs a little sooner in the east and northeast, usually during the last week of September.
The average then moves into the first week of October for much of central and western South Dakota.
Today's warmth will be replaced with cooler air tomorrow, followed by another reinforcing shot of cold air for the weekend.
Aberdeen has already fallen to 36 this week, and there's more of that type of cold coming for Saturday morning.
