Severe storms, heavy rain possible later today & tonight

Severe thunderstorm risk for May 17, 2019
By  | 

Sioux Falls KSFY Severe Weather Center meteorologists are closely monitoring the potential for severe thunderstorms later today and tonight.

Thunderstorms will rapidly develop across south central South Dakota and north central Nebraska late this afternoon and move northeast through the evening and into the nighttime hours. Storms will likely be severe with the threat of large hail, damaging straight-line wind gusts and even tornadoes. In addition to the severe threat, storms will also produce very heavy rainfall of 1 to 2 or more inches.

The most significant threat for severe weather will be across extreme southern and southeastern South Dakota and across much of central and northeastern Nebraska. The best chance for tornadoes will be late this afternoon and this evening generally south and west of Sioux Falls across central and northeastern Nebraska and extreme southeastern South Dakota.

While scattered thunderstorms are possible in and around Sioux Falls late this afternoon into early this evening, as of right now the best chance for storms in Sioux Falls will be from mid to late evening through the late night hours. This could change, however, so it is very important to stay weather aware today.
