I need to drill my new tank for a over flow does anyone know if temp of the glass matters it's only been in the 50s here in michigan and I want to do it outside

I think you would be alright, typically the problem with drilling glass is it gets too hot. Thats why you water cool the bit

Its not the hot or the cold that really matters (to an extent obviously, extreme heat melts, extreme cold makes even metal brittle), its a large rapid change thats really bad. I doubt you will get those kinds of temperatures if you drill properly with cooling even if its a little chilly outside.

Drilling dry till its good and hot then throwing ice water on it would probably be pretty spectacular though...

I did one last night... about 42. I do them outside and constantly run the hose over the hole to keep it a constant temp and to get the glass dust out. I go pretty fast, but it won't heat up with the water running.
