You'd be hard pushed to make this look cold and frosty Ali as it was taken on a warm day looking at the lighting. You could change the tone completely by making it mono and then adding a cold blue hue to it, this would certainbly make it feel colder. Adding frost is not easy, at least to make it look convincing. Actually snow and rain are a doddle compared with frost.
I've had a quick play just to show you what I mean with the blue effect but I am not claiming anyone would be fooled that it was a frosty morning. Does make it a bit colder though
Cheers.
