Plastic was put down, 2" 150 density foam, mesh, then I installed the pex tubing. My question, it was raining and snowing on Wednesday when I installed the pex, so water was sitting on top of plastic under the foam. Concrete guy insisted, he had to pour the next day in the mourning. So concrete floor was poured on wet foam and plastic, somewhat of a mini swimming pool. Will this cause a problem in the future with the concrete?
Thanks
Eric.

Eric in mosty probability the majority of the water has/had worked it's way to the surface of the concrete.  Concrete although made up of water will displace the water.  I have seen as much as 1"+ in footers when poured.  When you pour look at the ends of your pour and you will see the water coming to the ends.

I agree with John - your concrete should be fine.  If using an experienced finisher or concrete contractor they do usually not take many chances.  They do not want to have to replace.  If this is a slab I would be more concerned right now with it freezing.  You mentioned snow so I am guessing it is not Miami.  If it is cold there I would have covered the slab with blankets for about a week unless the ambient temperature is constantly above freezing or might dip down to mid 20 for a few hours it should be okay.  When I was around the trade we always in the cold weather recommended blankets; then even encouraged the use of a lot of straw on top of the blankets like a min. of 6" to 12" for a week or even longer when it was very cold.
