Sounds like moisture is getting into the ignition. This could be due to bad gaskets. I would replace the distributor cap and rotor, pick up some high temp silicon sealant, replace the parts and LIGHTLY put silicon sealant around the distributor where it meets the mounting bracket. This should keep the moisture out of the ignition.

Depending on the year, it's likely bad wires or a bad distributor cap. You can recreate the problem when it's dry by filling a squirt bottle with salt water and spraying the wires with it while the truck is running. You'll either get a nice light show or it will start to stumble/stall.

-First check for broken spark plug wire.

Don't think It's the rain.. When was the last time you had plugs and wires done... I went thru the same problem and it was simply a bad Wire...Good luck...

bad distributor cap and or ignition wires.

If this is only stalling in the rain, you are pulling moisture in the ignition system, or fuel system. When stalling if it cut straigt off ( no studdering first) its usually in the electrical system. If it studders first prior to stalling, Its usually in the suel system. In the Night time hours (after dark) open your hood and look for electrical arching. This will give you a map to followto seal up tour electrical issue if it exests. If it is in the fuel system, the first thing I always chack.replace is the fuel cap as the gaskets deteriorate over time and release pressure causing a drop in fuel pressure in the system. Good luck

Check the state of your engine's ignition system. Normally, rough running in the rain or during hours of high humidity indicates a worn/damaged ignition distributor or associated components.

check the idle air control motor

The problem in the Jetta could very well be with the ignition coil. I had the same problem for a long time and tried the usual replacing plugs, wires, etc, but nothing seemed to work.

It ended up being the ignition coil which over time, managed to sustain very small cracks. Even a small amount of moisture would cause all sorts of problems.

I replaced the ignition coil and had no problems after that.
