 CONT: Towards the beginning of the final episode of the miniseries,  Louis Verner and Sidney Enderman are walking through the streets of  the town of Centennial. When they first start their journey, it is a  nice sunny day. A few seconds later as they walk past Zendts old  store and behind the hotel to meet Cisco Calendar, it is suddenly a  drab, overcast day and there is a bit of a dusting of snow and ice  on the ground.
