Prohaska Family Memorial Park
Prohaska Family Memorial Park is a ski area in United States, at about 378 m. Its mapped area is about 1.1 km across.
Over the last twelve winters the ERA5 weather model gives it 84 cm of snowfall a season, 2,539th (tied) of 3,069 worldwide and 422nd in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (125 cm), brought more than twice as much as the leanest, 2023/24 (49 cm). December brings as much snow as January here (23 and 20 cm on average).
Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.

We do not show a snow depth here. The weather model we use reports snow lying on the ground — it knows nothing about grooming or snowmaking, and it is not the base depth a ski area publishes. In Japan we can check our figures against 234 weather stations. Outside Japan there is nothing to check them against, so we do not print a number we have not verified.
