After trying to sleep I awake to find that the boundary that was in SE Iowa has exploded into a line of strong thunderstorms. These Storms extended from near Lynnville to Searsboro and then splits into two distinct lines, one extending SE toward Ottumwa and Keosauqua. The other line extends east from Searsboro to Thornburg and then SE to Lockridge. A few other showers have also developed in Washington County. Looking back west, another storm was located east of Storm Lake in Buena Vista County. The MCS that was in Nebraska is just entering into Iowa. It continues to weaken.

Also a Severe Thunderstorm Warning is in effect until 3:15 AM for Turner, Lincoln and Minnehaha Counties in South Dakota. This includes the City of Sioux Falls.
