Now that he's done it once, he'll try to do it again.
Some of the warning signs are, as you mentioned, nosing around in the snow, walking very slowly, pawing at the ground, etc. Horses love to roll in loose sand as well.
Next time he acts like he wants to lay down, put him to work hard. Make him circle, sidepass, back up, serpentine, anything to get his mind back on the job at hand.
If he does actually manage to drop before you can stop him, do not just wait until he's done and he decides to get up. Get after him and force him to get up right that instant and then put him to work on the ground around you. If you have to kick him in the side to get him back on his feet, so be it, but he needs to learn that rolling under a rider is never okay.
It's way too easy for the rider to end up with a broken leg or worse when a horse just suddenly decides that they want to roll.
Always remember that feeling of looking at a big, open country over the ears of a good horse, seeing a new trail unwind ahead of you, and that ever-spectacular view from the top of the ridge!!! Follow my training blog: http://robertsontraining.blogspot.com/
