Key Messages
- A band of showers and storms sweeps through the region this evening. While the severe weather threat looks to stay just northwest of the local area this evening, one cannot fully rule out a weak tornado northwest of a Rochester, MN to Wausau, WI line.
- While cooler after today, near to above average temperatures linger into early next week with the threat for rain returning mainly Friday into Saturday and again late Monday into Tuesday.
