A severe thunderstorm complex produced a long lived damaging wind event that traveled from north to south from northwest Iowa to southeast Iowa during the overnight hours. The winds produced damage over a large area of Iowa. This type of storm is known as a derecho, a long lived, widespread bowing thunderstorms that producing strong, damaging winds. You can see in the graphic to the left all of the strong wind reports in Iowa during the early morning hours.
The graphic also shows where the storm complex began in far northern South Dakota. Other storms rolled through the Minneapolis area yesterday producing tornadoes and another batch of storms made its way through Nebraska and Missouri overnight.
As for today, things should be a bit quieter here in Iowa. Some strong storms are possible in southwest Iowa today, but the only threat with these storms if they develop is large hail. You can see in the graphic to the right the area at risk for severe weather later today.
As you can see, the bulk of the threat is well of to the south and east of Iowa today as the frontal system moves through. But that doesn’t mean we’re out of the woods yet. Several rounds of showers and thunderstorms are possible later this week, beginning with yet another severe weather threat to kick off the work week.
This is a very conditional threat for Monday. You can see in the graphic to the left that much of the state is under a slight risk for severe weather. This is a very low end risk because the models are having a tough time nailing down a good outline for this event. We may also see more severe weather on Tuesday. but for now we should take these one at a time.
If anything changes with tomorrow’s threat we’ll have an update on that this afternoon. Otherwise, if you have any pictures of the storms from this morning or the damage they left behind, please email them to [email protected]
