A small crack in the axle ABS tone ring(s) could give similar symptoms, though not just in wet weather. My 2002 Continental showed it mostly at slower speeds when coming towards a stop. You could pull the ABS fuse (ABS warning light comes on) and go out for a test run and see if the problem stays, or goes away. In my case I had to replace the left front axle as the tone ring comes with it.
Could the wet weather be causing a damaged ABS wheel sensor to fire off inadvertently? I'd check the sensors and the tone rings. And lousy low grip tires could be the culprit too.
