when is the ground warm enough?

hello, I'm in SE Michigan and though it was 70 here for a few weeks, now it's snowing, and will be for about another week. someone purchased for me herbs (basil, oregano, etc..) and poppies. when is the ground warm enough to put them in and how much water do they need in window pots? thanks in advance.
