The possibility of severe weather in Sioux Falls will continue through Wednesday, with heavy rainfall and the potential of flooding the main risks, according to the National Weather Service.

The first round of storms is possible starting at about 6 p.m. Monday into early Tuesday morning, with slight risks of hail, winds up to 60 miles per hour and flooding, with rainfall amounts of up to a quarter of an inch.

A second round is possible beginning Tuesday afternoon through the evening, again with slight risks of hail, high winds and flooding.

All told, as much as 2 inches of rain could fall by Wednesday afternoon in Sioux Falls, including totals from storms that moved through the area Monday morning.

The NWS states there is also a slight risk of flooding in the area through Wednesday morning, depending on rainfall totals, with soil saturation leading to the potential for ponding of water and rises in rivers and creeks.
