A slight or enhanced risk of severe weather exists over the entire KWWL viewing area today.

While strong to severe storms may happen at any time today, the main threat will be late this afternoon and evening and possibly overnight depending on storms to the west.  As of 6 AM, storms are tracking through our southern counties. They are strong with a few that may become strong enough to have severe wind gusts or isolated large hail. 

The current storms are also producing heavy rainfall as they train over the same areas, so localized flash flooding may occur this morning. Radar estimates are over 3 inches in southwestern Iowa County. These storms will also set the stage for problems later today. They will put out outflow boundaries that could set off more storms later in the morning and early afternoon. The main energy arrives this afternoon, though, with a low pressure system and a warm front tracking in. 

When the afternoon storms start, it will be fast and they will be strong. Probably going severe within 30 minutes of them forming. They will have large hail and damaging wind potential along with the possibility of tornadoes.

As the storms mature, they will turn more into a damaging wind event with a bow echo forming and producing damaging winds as it tracks over real estate. Where these storms begin will determine what form of severe weather we will end up, along with what time they will be here. The morning storms complicate trying to figure out timing. 

Expect to be rocking and rolling somewhere in the area later this afternoon and evening. Right now, I will put a tentative time of 4 to 11 for the main show, but that could change depending on any midday storms and any development in the Dakotas or Nebraska.  With or without severe weather, we are expecting heavy rainfall, especially in the southern half of the viewing area.
