Now-Later, we have the same problem. Same weather conditions. It has been wet and cool, but it has been warming up in the past week. I grew red and green pepper plants in big pots and they are doing so good. I just came in from checking on them. I was thinking about trying one tomato plant in a pot next time to see how well it will grow that way. Momof23goats is a very wise soul who could propably give you some advice. I like reading her posts because she knows so much. Hope you can save them somehow. Maybe they will come around for you I hope.
