Our only real chances of rainfall in the next seven to 10 days will come Thursday night and Friday, and rainfall amounts will be modest. Most of us will see under one-quarter inch of rainfall with the potential for more in west-central Minnesota.

The air will remain muggy Wednesday and Thursday with dew points mostly in the 60s across southern Minnesota. Behind that front, dew points will finally drop into the 40s and 50s Saturday, which will make it feel fall-like, especially combined with much cooler air.
