Not a good weekend for many in western Iowa, where rainfall totals reaching 5” over the last 24 hours is creating flash flooding conditions in some areas. Showers and thunderstorms continue to persist this afternoon, but are not expected to turn severe. Today most of the severe weather should stay south of Iowa. The focal point of today’s threat should remain in Missouri, however some strong storms may affect portions of southern Iowa later today and tonight.
Some of these storms, if they do reach southern Iowa, may pack strong winds and some large hail. Otherwise the severe weather should stay away from Iowa for the most part.
Turning our attention to Sunday,a slight risk for severe weather has been expanded to include most of Iowa. Storms are expected to fire Sunday afternoon in portions on Nebraska. This is where the best threat for tornadoes exists. The storms will make their way towards Iowa. Sometime around or after sunset they should reach the state around the time a very strong jet will ramp up and support severe weather throughout the overnight hours over the state.
Although an isolated tornado or two is possible, the greatest threat will come in the form of strong damaging winds and large hail. Again this could turn into an all-night severe weather threat so we’ll continue to monitor this potential. Anyone with outdoor plans during this week should have a way of staying updated to the latest forecasts.
This stalled warm front will also set up a clash of the air masses over the state, producing several threats for severe weather during the new week. You can read more about that in our previous postings.
We will continue to monitor all these threats and bring you more updates as they become available.
