Frost Advisory for all of Southeastern Wisconsin

We started out this morning with patchy frost to the west of Lake Michigan.  Fond du Lac actually got to freezing this morning, while Milwaukee dropped just under 40 degrees.  Tonight the entire area is under a frost advisory for Friday morning.  The clear sky and the light wind will allow temperatures once again to fall back into the low to middle 30s.  

This isn't out of the ordinary for us.  The first couple of weeks of October typically feature some sort of frost.  The exception is right along the lakefront where warmer water temperatures help to insulate the land.  We start to see a better chance for frost along the lakefront near the end of October!
