URGENT: Mother Nature to Deliver Dangerous Mother’s Day

This is not what many want to see on a day many will spend with loved ones.  A significant outbreak of severe weather is forecast to occur over a large area on Mother’s Day, including here in Iowa.  The graphic below spells it out pretty well.  You can see the area outlined in both the slight and moderate risk.  Much of Iowa falls in the target area and will face a significant potential for severe weather.

day 2

The storms we saw late last week had the potential for an isolated tornado or two, but the primary threat came in the form of large hail and a few strong wind gusts.  Sunday could be a drastically different story.  All parameters look particularly strong for Iowa and much of the Upper Midwest for explosive thunderstorm development Sunday afternoon and into the evening hours.  Of particular concern here in Iowa is the conditions which will favor the development of a few, independent supercells, rather than a more linear bowing structure of storms.  This setup gives us concern that not only are tornadoes possible, but strong, long-track tornadoes as well.

As we have seen in years past, Sunday thunderstorm outbreaks can be dangerous because many are often not paying as close attention to the situation as they venture out.  With graduation ceremonies and parties, picnics, Mother’s Day festivities and any other activities on the docket, it is all the more crucial that EVERYONE stay up to speed on the latest information.

Bottom line, there is a potential for a significant severe weather outbreak across Iowa on Sunday.  Very large hail, destructive winds and strong tornadoes are all possible.  We will have an update later today as we get a better handle on what to expect tomorrow.  For now, please share this post with everyone you know in the affected area.  This is a threat that should not be taken lightly!
