I have had to do that a couple of times; once, I rode from Rye, NY to Ocean Shores, WA in 48 hours and can say with certainly that will drive the moisture out of the crankcase (and most of the spirit out of your soul too).
Like others have said, cold temperatures combined with short riding distances just do not warm up the crankcase enough to drive off the water. It should not be much of a problem as long as there is not an excessive amount of water in the oil, making a foamy emulsion (Boys!) that will not lubricate the main journals (yep, I said that).

10 miles will not warm the oil enough to dry the condensation out. Take the long way home and get the engine good and hot.
