When it starts
Crystal Mountain, Dec 20–21, 2025: the model's run on the day said 4.7" skiable over 2 days, best Saturday at 3.5" (Nice day); the Morse Lake SNOTEL pillow gained 6" of depth. Close.
Close. 4.7" skiable in the model, 6" on the pillow: inside 3" or 30%.
Pack going in: 30" on Dec 19, 31" on Dec 20. The storm total counts from the first reading, so snow after 5pm the night before is in it.
| Day | Call | First chair | On hill | Skiable | Starts | Pillow before | Pillow after | Gain |
|---|---|---|---|---|---|---|---|---|
| Sat Dec 20 | Nice day | 1.8" | 1.7" | 3.5" | ~1am | 31" | 32" | +1" |
| Sun Dec 21 | Stay home | 1.1" | 0.1" | 1.2" | ~5pm Saturday | 32" | 36" | +4" |
Model: the run on the day (Open-Meteo Previous Runs, best_match). PowHound does not keep superseded live forecasts, so this is not the number you saw the night before. It is usually closer.
Clocks, local time: first chair 5pm–8am, on hill 8am–5pm, skiable is both. Stay home under 2", Nice day 2–8", Full Send 8" or more.
Pillow: snow depth at the Morse Lake SNOTEL station, read once a day around midnight. A day's gain is the next midnight reading minus that day's, so it runs midnight to midnight, not 5pm to 5pm. Depth is not snowfall: new snow settles and blows around, so the pillow usually reads under what fell. Not the resort report.
Verdict: close is within 3" or 30%. Season numbers and method: llms.txt.
