The Storm Prediction Center is maintaining a moderate risk for most of the state. This are could experience a nearly complete life cycle of a large severe weather event.
Let’s break this down chronologically. Initial development is expected to being near the Missouri River. The first storms to fire will quickly turn into supercells, capable of producing very large hail and numerous tornadoes. Some of those tornadoes could be strong.
Tale a look at the graphic to the right, you can see the area at greatest risk for tornadic development today. Now the threat of tornadoes should begin to subside as the sun sets. This does not mean the end of the severe weather threat. That’s supposed to continue well into the morning hours.
As the storms move east, the threat will shift to a major straight line wind event. Take a look at the graphic to the left. You can see much of the state faces the real possibility of a widespread wind event tonight.
As we’ve said for nearly the past week, this is of major concern with a saturated ground. The wet ground will not support area trees as well and puts them at greater risk of being uprooted by the winds.
The tornado risk does remain for the entire night, but again, after sunset, it’s expected the primary danger with these storms in central and eastern Iowa will shift to strong, damaging winds.
We will monitor the situation throughout the day and will bring you live coverage when needed and also LIVE VIDEO from storm chaser Ben McMillan as he tracks these storms today.
