I think long wet grass does not respond all that well to reel mowers. The front roller may roll the grass flat, then it may stick to other wet grass for a while, and pop back up after it's too late for the reel to fan it onto the bedknife. Even if your reel is properly adjusted, short wet grass is one thing, but long wet grass is another. You'll be able to mow it when it's dry, unless it is quite horrendously long.
