Throughout the series the skies can change from cloudy/party cloudy/full sun, depending on the camera angle or perspective.

In some of the wide shots of throughout the series, it's clear that the Albuquerque is the one that exists from 2015 and later rather than the one which existed in the early 2000s. There are homes in areas which were vacant in 2003 and there buildings missing which have been torn down in the interim.

Mike Ehrmentraut's granddaughter Kaylee is clearly the same age as she will be during the run of Breaking Bad. Since Better Call Saul is a prequel to that series, this should not be the case.
