Chances are the plug wires and distributor cap needs replaced. If they are bad, they will arc when they get wet. Here is a test. At night, in the dark, start the engine, open the hood, and lightly mist the plug wires to see if anything sparks. If it does, that is the problem.
Let me know what you find.
