Here we go again, the week wraps up with another threat for severe weather across most of Iowa. But this threat is much different from the strong storms and heavy rain we’ve been dealing with the past few days.
Storms are expected to develop to the northwest of Iowa in parts of South Dakota. As these storms develop,all modes of severe weather are possible, tornadoes, large hail and strong winds could come from the first batch of supercells that develop in the Dakotas.
Taking a look at the graphic to the right, you can see the risk area for torandoes. Although possible here in Iowa, the greatest risk comes in the first hours of the severe weather outbreak to the north and west of Iowa. As the storms mature, it’s expected they’ll form a more linear structure and move into parts of western Iowa. By this time a threat of tornadoes should remain but the primary threat will shift to strong damaging winds.
This threat may last well into the evening and overnight hours across much of the state. In the graphic to the left you can see the area at greatest risk of strong winds tonight. It could be a long duration event for Iowa, but the hope is with a frontal boundary moving through the state instead of lingering, the threat of heavy rain will be minimal. But with all the rain some areas have received this week, flooding is still a concern and will have to be monitored tonight, once again.
We’ll continue to monitor the latest updates throughout the day and bring you the very latest as this new chance for severe weather begins to materialize out west.
