From what I have read the two big things are don't blow the highlights and don't believe your meter. If you blow the highlights you will have no detail in the snow and if you believe the meter it will try to make your snow gray.
The other consideration is condensation, the method I used was to place the camera in a bag and place it were it would be able to acclimate to the outside temperature, then the reverse place it in a bag before returning it to room temperature. I did get some condensation on the bag when returning it to room temp. Also keeping any spare batteries warm when out is recommended.
As no one has responded having experience just do an internet search for photographing snow. Looking forward to seeing the pictures
