[While he's doing his searching thing, he might run into Sakura - who attempted to get back to the castle once the snow really started getting worse, and separated from Syaoran, she ended up getting lost. She's used to sandstorms, maybe, but certainly not being in them -- and being lost in the snow is difficult. Plus, without her ability to communicate with things due to the magic block, she can't exactly stop and ask for directions, either]
[She's warm enough, for the most part-- just uncertain and definitely wanting to get back]
