Tuesday's cooler-than-usual temps will be replaced by much warmer numbers on Wednesday.
Fall officially begins this weekend, but before that happens, we're experiencing a battle of the seasons. There's a chance we can be 20 degrees warmer from one day to the next. This will occur Tuesday to Wednesday, as temps rebound from the cool middle and upper 60s in eastern KELOLAND to near 90 on Wednesday.
We've had quick turnarounds like this in the past, but it usually occurs the other way. Temperatures are more likely to decrease from one day to the next.
Since 1990, Sioux Falls has had 13 instances where the afternoon high changed by at least 20 degrees. Nine of those times, the temperature fell by at least 20 degrees from one day to the next.
The biggest difference happened just last year when Sioux Falls high went from 96 degrees on September 11 to 67 degrees on September 12, a 29 degree swing.
This is the most active week to have the big temp swings too. Of the 13 times it has happened, nine of those have occurred from September 16th to the 23rd. It's just a sign of the changing seasons. Fall officially starts Sunday afternoon.
