Last year I had a tomato problem that you describe and I beleive it just went away on it's own. I copied the info below from a website...

Many serious tomato diseases, including curly top, mosaic, fusarium and herbicide injury, begin with rolling leaves. But if your plants are green and no other symptoms appear, it's probably plain old "tomato leaf roll." It's a temporary disorder resulting from excessively wet soil, especially after heavy rains, or bright sunshine on young plants. It doesn't affect the plant's growth. A normal crop of fruit is usually produced. The rolling typically disappears in a few days when the soil dries out. 'Big Boy', 'Floramerica' and 'Beefsteak' are affected most often.

Hi geran - If you will Google "tomato leaf roll" you'll find many pictures you can compare to your plants as well as info on its many causes and prevention techniques. You'll also find several discussions about it over on the Growing Tomatoes forum and on the Tomato Pests & Diseases forum here at GW.

If that is the problem, and given what you say about the weather it is quite likely, then as ruthieg said, it will go away on its own once the plant adjusts to the weather. Meanwhile avoid over-watering (one of the main causes), high nitrogen fertilizing (also a primary cause), and homemade sprays. ;) It is always best to first diagnose the problem before applying any treatment. That way you don't end up making the problem worse.

I sparayed them with a homemade mixture of lime juice, dish soap and baking soda - figured it couldn't hurt any.

That all depends on how much and what you used. Homemade soap sprays can burn and stress plants if mixed too strongly, over-applied or if applied in the heat of the day or direct sunshine. There are also many posts about it over on the Tomato forum to review. Good luck with your plants.
