When do they come out

I can't wait to see my snakes again this year. What kind of dail temperatures do we need to get them to come out.

Thanks

The first snakes in my Outdoor enclosure emerged two weeks ago,
when it was still below 60°F but sunny.
They basked under a plexiglass plate and went back to their den when
the frost came back.
I hope to see them again the next but one week.
Than day temperatures shall raise up to mid 60´s.
Sun seems to be more important than temperature.

I am wondering when they come out in the southeastern Wisconsin area, about 20 miles from lake Michigan.

Thanks
