When it starts
Heavenly, Jan 2–4, 2026: the model's run on the day said 5.6" skiable over 3 days, best Sunday at 5.2" (Nice day); the Heavenly Valley SNOTEL pillow gained 17" of depth. Model shy.
Model shy by 11.4". The usual direction: the 2025–26 backtest ran low on storm days.
Pack going in: 22" on Jan 1, 21" on Jan 2. 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 |
|---|---|---|---|---|---|---|---|---|
| Fri Jan 2 | Stay home | 0.1" | 0.0" | 0.1" | — | 21" | 29" | +8" |
| Sat Jan 3 | Stay home | 0.2" | 0.1" | 0.3" | ~5am | 29" | 42" | +13" |
| Sun Jan 4 | Nice day | 3.1" | 2.1" | 5.2" | ~9pm Saturday | 42" | 39" | -3" |
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 PowHound does not keep superseded live forecasts, so this is not the number you saw the night before.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 Heavenly Valley 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.
