What was the weather like in northern parts 13,000 years ago that humans would consider and make the trek from Asia to NA?

I recall learning years ago the prevailing idea was that nomadic groups of people followed the migration of the megafauna they hunted. Looking at today's Inuit (eskimo), and other Arctic indigenous peoples, it's unlikely that winter conditions especially when such a large portion of the Earth's surface was covered by glaciers, would deter the movement of determined (read: hungry) humans.
