After landing with nearly full fuel tanks in just above freezing conditions the flight crew of a B737NG planned--but failed--to check the tops of the wings for cold soaked fuel frost prior to their subsequent takeoff. A lengthy layover permitting intervening distractions may have been a contributing factor.

Narrative:
During the descent into den; I was aware of the fuel temperature and the fact that we were tankering a significant amount of fuel. I mentioned to the first officer that we would not be loading much fuel to raise the fuel temp and would probably have csff [cold soaked fuel frost]; with probable de-ice requirements. Fifteen minutes after arrival; I checked both wings and it appeared as if we had csff. I planned on checking the condition of the wings prior to departure. Due to a very early arrival and an already long (55 min) turn we had almost 1.5 hours in den. I guess I had too much time on my hands; as I forgot to re-check the condition of the wings prior to departure. I realized my mistake after takeoff. It is possible that I departed with cold soaked fuel frost on one or more wings; but I don't know.
