An active warm front and low pressure center has finally pushed areas of rain into southern Minnesota. Some of the rain is locally heavy, with rainfall already in excess of 2" in some areas.
As the main body of the system finally moves through Friday, expcect areas of locally heavy rainfall.
It's not often you see a swath of rainfall forecast at 2" over much of central and southern Minnesota. Check out the graphic from NWS below.

As storms "train" or move over the same areas dumping heavy rainfall, it appears local areas will receive enough rain to meet or exceed flash flood guidance.
Here are some links to keep track of the rain.

Amazing to me how serial drought years can be washed away by a good season of recurring showers! :-)
The flash flood guidance map is interesting - is there any information about what goes into determining the amount of rainfall a given area can receive before flooding occurs? Thanks!
