A Colorado Low will lift across the region late Thursday into Friday, bringing moisture to a decent swath of the state into western Minnesota. The exact location for where the heaviest rainfall sets up, which could exceed 2", is still a little uncertain. Models place it somewhere across the southeast, east central or northeast, so hoping for a little better confidence in time.
We're setting up for a more active next several days. The first system coming through tomorrow (Wednesday) won't bring much moisture overall. Its the system towards the end of the work week that will bring another 1-2" type amounts to mainly eastern South Dakota.
