From a record-setting blizzard in the west to minor flooding from downpours in the east. With more moisture set to arrive this week, moisture records could fall.
Rapid City is both the closest to and most likely to break the mark. The Rapid City airport has picked up 5.38" of total moisture this month. That's almost four inches above a normal October. The record is just above five and a half inches, something that could easily be surpassed over the next couple of days.
That mark only dates back to 1998 but Sioux Falls' is more than 100 years old. In 1911, nearly seven inches fell. We're at 2.78 inches so far, so the record's not in jeopardy.
Aberdeen is roughly three inches short of the October mark but Pierre's number is more within reach. We currently sit at 4.66" of total moisture, after combining rain and snow. If Pierre picks up just over an inch before Halloween, we could beat the record though computer models are keeping us well under an inch for the next couple of days.
