Gardening question, do any jellies have tips to stop splitting in Supersweet 100 cherry tomatoes after a heavy rain?

I love fresh out of the garden tomatoes, and the 100’s are so so good. I even have people I give some to that will ask in the Spring how they are doing. These are excellent tasting, but after a heavy rain the ripe one’s tend to split their skins and then breakdown and get crappy. Any thoughts on how to stop this? It’s due to the heavy rain, but lately that’s all we get.
