A Break Before More Severe Weather Wraps Up Week

It’s not much, but for those struggling to fight back flood waters in central Iowa today, they’ll take every dry second they can get.  With the exception of a random pop up thunderstorm, most of the state should stay dry today and tonight.  That’s the good news.  The bad news is the heat and humidity are going no where and more storms will arrive by Thursday Night.

The only good news is this could be the beginning of the end.  Thursday severe weather is expected to begin in the Dakotas, where a cold front will begin pushing through the Upper Midwest.  The bad news is it won’t move all that fast.  Although reaching western Iowa by Thursday Night, the front may not clear the state until Saturday Morning.  This means as long as the frontal boundary is lingering in the area, severe storms and the heavy rain that comes with them remain possible.
