First some frost for some, then a methodical warming trend

MILWAUKEE (CBS 58)--Frost Advisories are getting ever so close to us.  Tuesday morning one was in place north and west of us.  I have a feeling an advisory will be issued in or near our area over the course of the next few nights.  Some of us could experience lows in the upper 20s! We'll have clear skies and fairly quiet winds.  So bear this mind with your tender plants and vegetation. Highs in the middle of the week will only be in the 50s and 60s.

I do see a milder trend setting up by the end of the week. In fact by Saturday, the first day of October, highs could be near 70.
