Yes, a sudden increase in moisture can cause them to split. The toms absorb the moisture, expanding ever so slightly, but enough to split the skin that can't expand quickly enough to accommodate it. The same thing can happen if plants receive a lot of sudden moisture after the soil has dried out.
Yes, we've got a lot of rain forecast today and most of my outdoor tomatoes are nearly ripe, so I'll pick them all and bring them indoors to finish off before the rain starts.

Yes I noticed one of mine had split around the top - Thought it might have been the cold, but it was probably the rain then.
thanks for the info, i also have grown toms this year for the first time, and all above applys to my situation.
