Spring?

With temps nearing 80 tomorrow, and in mid 70s today, is Spring here? Or will Oklahoma remember that it wants to punish us by sending an ice storm mid-March? We're getting ready to till soil and plant, um, plants. Herbs, culinary and aromatic, and veggies. No more pots on a patio. A real, honest garden. We'll just have to see if we get any rain this year.
