Extreme amounts of precipitation fell around the Sioux Falls area on Thursday into Saturday. The featured map presents NOAA MRMS precipitation estimates for this period. A large area received at least six inches of precipitation with a considerable area receiving over a foot. This amount of precipitation over a short duration of time lead to historic flooding of the region. These flood waters are now working downstream into the Missouri River with a number of observation points along area rivers at or near record crests. To make matters worse, dangerous heat will be present on Monday with heat index values well above 100 degrees.
