You probably got water in the distributor cap, take it off and blow it out with some air. Should fix your problem. Let us know.

There is most likely an electrical connection that got wet and needs to dry out. I had that problem and it was the wiring that plugged into the distributor. The wires were loose and allowed moisture to get in and interrupt the electronics. Since it's backfiring, you should inspect all wires concerning the distributor module.
