It would be quite feasible for this to occur in an aircraft with bladder style fuel cells such as a Cessna 182, 180 or perhaps a Chipmunk.
Where there is a ripple in the bladder and ice were to form, melting latter and finding its way to the fuel pickup, but it would be just as likely as a liquid.
With a wet wing tank or a solid tank as already mentioned it should be noticed with a blocked drain.
One thing that is worth noting is prior to commencing a preflight check it can be worth giving the wing or aircraft a reasonably firm wiggle to redistribute any water, hopefully to a drain point (make sure you give a reasonable time to settle).
