What does your Flight Manual say about flying in snow. If it says you should not, then don't. If it says you can, then be sure to understand the limitations that are prescribed. Whiteout is always likely on take-off and landing. Do you know and have been instructed on snow take-offs and landings.
Saw a swan who hadn't had mums instructions and supervision on landing on the white stuff come to grief in a spectacular landing as white out conditions existed and the poor swan thought that the surface was several feet lower than it actually was. There were feathers and snow all mixed up, and it took a while for the swan to rearrange it's feathers back into flying condition.
If your pitot hasn't heat then for sure you should stay in bed.
