Well dont keep the secret any longer. did you water them ????????

Generally as long as weather and water are adequate lettuce does fine and will rebound from wilting. I have even seen what I would have thought impossible. Frozen lettuce turn to mush and then recover completely once the sun came out.

On the warm days give the lettuce lots of water in containers, never let it go even close to dry.

Thanks for the advice. I did give it adequate water. Tonight is supposed to thunderstorm, so perhaps I will bring them inside until tomorrow, where the weather will be cooler which they love. I hope they do rebound.

Aw, and they have to miss out on all of that nitrogen rich thunderstorm rain? ;-(
