The usual low-lying spots of the Arrowhead and Iron Range might get pretty cool tonight, perhaps some patchy frost. While fall does come early closer to the borderland, if a frost does occur tonight, it's a little early this year. Meanwhile, the lakeshore areas will stay warmer due to the Lake. The Apostle Island might even stay in the 60's tonight. Toasty! Despite the recent cool and dry conditions, warmer air will return to the western Great Lakes this week. Summer's not over yet!
