Ursa 4.6K g2 filming in snow

Hi guys, I‘ll have an important shoot this Sunday. The weather was supposed to be cloudy but unfortunately we will have snow and bright sunlight and a narrow timeframe of shooting (11am to 2pm). We film on the URSA 4.6K g2 with Schneider Kreuznach lenses. Do you have any tips for us shooting in these conditions?
