All-time record rainfall hits Sioux Falls Sunday morning, more on the way

A strong round of overnight thunderstorms rolled through Sioux Falls early Sunday morning, bringing with them more rain than has ever been recorded in the city, according to the National Weather Service.

As of 7 a.m., the NWS had recorded 5.22 inches of rain at the airport in Sioux Falls, an all-time record for one day. The previous record was 4.59 inches on August 1, 1975.

The heaviest rain was pretty localized according to Tim Masters, a technician with the NWS in Sioux Falls.

"Some areas got a lot, and some not so much," Masters said. "This was a possibility which is why we were looking at excessive rainfall today and the day before."

With even more rain still coming into the area, a flash flood warning has been issued through 9 a.m. for most of Sioux Falls and extending east into part of western Minnesota.

Masters says the NWS hasn't heard of a whole lot of reaction yet concerning flooding, but it's still a danger.

More rain and thunderstorms are expected throughout the day Sunday, with a hot week ahead for Sioux Falls. Temperatures are expected to be in the high 80s by Wednesday.
