When it starts
Mt Bachelor, Dec 18–21, 2025: the model's run on the day said 11.3" skiable over 4 days, best Friday at 5.2" (Nice day); the Three Creeks Meadow SNOTEL pillow gained 3" of depth. Model heavy.
Model heavy by 8.3". New snow settles as it lands, so the pillow reads under what fell. Read heavy as soft.
Pack going in: 1" on Dec 17, 0" on Dec 18. 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 |
|---|---|---|---|---|---|---|---|---|
| Thu Dec 18 | Nice day | 1.8" | 1.2" | 3.0" | ~5am | 0" | 1" | +1" |
| Fri Dec 19 | Nice day | 3.4" | 1.8" | 5.2" | ~8pm Thursday | 1" | 0" | -1" |
| Sat Dec 20 | Stay home | 0.0" | 0.0" | 0.0" | — | 0" | 3" | +3" |
| Sun Dec 21 | Nice day | 1.0" | 2.1" | 3.1" | ~4am | 3" | 4" | +1" |
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 PowHound does not keep superseded live forecasts, so this is not the number you saw the night before.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 Three Creeks Meadow 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.
