It has been a long time since Iowa has had its share of a tornado, that’s for sure. Over a year. Quite unusual for Iowa, but that may change today.

The Storm Prediction Center in Norman, Oklahoma has posted a elevated risk for severe weather on the day on Sunday. A moderately unstable airmass thanks to dew points in the upper 50’s and mid 60’s, will begin moving into the region this afternoon. And, without capping, storms from last night will likely still continue North, dropping plenty of rain on Iowa. But, by the evening, things should really begin kicking.

An unstable airmass combined with modest shear will easily support supercell development late in the evening. Large hail, larger than golf balls at times, damaging winds, especially possible if a bow echo can develop, and a few tornadoes with the stronger storms. Flash Flooding is also a definite concern with the loads of rain we have received over the past few days and the soil remaining saturated.

Live Coverage is expected to begin at around 4:00pm this afternoon with a live chat and live severe weather coverage. Our chase teams have deployed to Southwest Iowa – you can make sure to follow them then too. Stay tuned to the Iowa Weather Network for the latest updates!
