Flash flooding will remain a concern through the morning hours in these regions, before the flood concern shifts slightly eastward through Missouri and parts of Illinois through the day.

The storms will eventually lose strength by mid to late morning, however, as the system moves closer to Chicago by midday storms, some severe, could fire up again. Meanwhile a frontal system approaching from the north and west will also reignite severe storms in parts of the Dakotas, and into parts of Iowa and Minnesota. A couple lines of strong to severe storms are likely there late Saturday and early Sunday.

As a result, there is an enhanced risk for severe storms in parts of the region, including Sioux Falls, South Dakota. There is a slight risk for severe weather from Nebraska to Illinois, including Omaha, Nebraska; Des Moines, Iowa; and Chicago.

Heavy rain in Southeast

A stalled stationary boundary continues to interact with tropical moisture in the Southeast. There have been reports of over 11 inches of rain in parts of the swamps west of Gainesville, Florida. Some of the towns in parts of that region of Florida have reported flooding, but it appears the heaviest of the rain is falling mainly over swampland.

Unfortunately, the chance for tropical downpours will continue through the weekend as the stationary front slowly falls apart. The National Hurricane Center is monitoring the entire system for possible tropical development, as a the low moves into the Atlantic Ocean over the next few days. However, chances remain relatively low that anything truly tropical develops from this.
