RECAP: Monday, June 16
The National Weather Service reports that at least two tornadoes touched down simultaneously in northeast Nebraska Monday as severe weather battered the Plains. Storm chasers streamed the twin tornadoes live on The Weather Channel before at least one of them slammed into the farming community of Pilger, Nebraska, about 75 miles northwest of Omaha. In all, there were at least 30 reports of tornadoes Monday and Monday night in four states (Nebraska, Iowa, Wisconsin and North Dakota).
In addition, heavy rain and flash floods ravaged the Plains as well. As much as 8.43 inches of rain fell in Canton, South Dakota, a town just outside of Sioux Falls.
Unfortunately, more severe thunderstorms are likely in the days ahead. Here are the details on current and forecast severe weather for the next few days:

Flash Flood Risk

Heavy rainfall this past weekend, in addition to soaking rain earlier this month, has left the ground saturated in parts of southern Minnesota, southeast South Dakota, northeast Nebraska and northwest Iowa. 
The Rock River at Luverne, Minnesota, crested at an all-time record on Father's Day. Sioux Falls, South Dakota picked up 4.71 inches of rain last weekend, pushing them to an all-time monthly rain record of 9.97 inches, through June 15.
Another heavy thunderstorm Monday brought 0.85 inch of rain to Sioux Falls in 5 minutes. Parts of Interstate 29 south of the city were blocked by floodwaters Monday evening.
Within a 24 hour time span between Monday morning and Tuesday morning, Canton, South Dakota (about 20 miles southeast of Sioux Falls) picked up 8.43 inches of rain!
Any additional heavy rainfall over this region will quickly runoff, leading to additional flash flooding of fields, roads, and rises on area rivers and streams.
Unfortunately, a complex of thunderstorms may bring locally heavy rain to parts of this region each evening through Thursday evening. 
Lightning is of course always dangerous. Keep that in mind if you have outdoor plans in the orange areas on our thunderstorm maps.
