White Christmas is defined by new snowfall on December 25, or up to 24 hours before, of at least one inch / 2.54 cm.

When you add cities, please confirm they have a population of at least 40,000 people. If outside the US, please also post a link to where the snowfall for that city can be verified (otherwise auction will resolve as N/A).

Auction closes on December 23. I’ll try to resolve ASAP after the 25th 🛷

Resolved for US cities based on data from the National Weather Service, eg

All other international cities will be resolved as N/A unless a source for 24 hour accumulation totals is proposed and accepted.
