Humidity set off Traction and Stabilitrak

I concur with the above completely. I would also inspect the harness to the coils.

Since nearly all the misfires are at cylinder #6, try swapping plug wires with cylinder #1.
If the problem moves to cylinder #1, you need a new plug wire.

If the problem stays with cylinder #6, try swapping COILS with cylinder #1.
If the problem stays with cylinder #6, you need one new spark plug.
If the problem moves to cylinder #1, you need a new coil.

feels like this is probably a coil breaking over to ground when it's wet. is my guess. Definitely do this coil swap. or I've even seen a loose spark plug cause weirdness.
