thats why we get whoops though! I got my first meteor75 during winter and learned exclusively inside for the first few months. it wasn't the best, but it was doable.
its not "bad" for the drone itself, as long as you have conformal coating and keep it dry in snow. It should actually keep the boards cooler, which is better.
Batteries are a different story, they can and will get damaged if they charge/discharge when it's too hot/cold for them. You can combat this by keeping them warm, safely, before you fly and when you charge. but ultimately it doesnt matter the drone or battery, the batteries will always have a shorter life in extreme weather.
you really have to be careful with warming batteries, but there are a bunch of options out there. the biggest thing is DO NOT get the powdered hand warmers for it, those work by exposing iron dust to oxygen and creating rust/heat through an exothermic reaction, you dont want that anywhere near battery terminals.
