Storms are re-forming late this afternoon and we’ll be here tracking them all night. There is an elevated chance of severe storms later tonight in SW SD and also in the northeast. We had some very good rain totals in north-central SD earlier today, with Mobridge picking up 1.32.” There are plenty of clouds left after the rains in central SD, which helps lower the chance of severe weather in the north tonight.
Unfortunately that rain JUST missed Sioux Falls after hitting almost every other spot around town. We do have limited rain chances later tonight, as it seems current rains will just miss to the north. There are two distinct areas worth watching tonight; supercells will try to get underway over the Hills, but have struggled so far today. More scattered storms are trying to develop out of North Dakota. These will push closer to Aberdeen late this evening before moving into SW Minnesota. This likely won’t happen until after midnight with this second storm system.
After some isolated morning storms come close to Sioux Falls, most will actually see some sunshine by the afternoon. Temperatures should warm more than today in eastern SD.
The best chance of rain this week looks to arrive Tuesday afternoon. We’ve got it at 40% East River and just slightly lower in the west. Severe storms are again possible, depending on cloud-cover early in the day.
After that, storm chances go down slightly. Given how dry it’s been this past month, we’ve trended lower on the rain chances.
