Yes but once the car is warm, it doesn't consume that much to keep température unless you open the doors, at least on my 2019 Tesla 3.
I found that pavement conditions, how much snow and ice is stuck to the car etc. have a bigger influence on range than temperature once the car is warmed up.
The trips I did during or just after a snowstorn always required some careful management of charge and keeping a good buffer.
