⚠️ Crew Callout Decision Matrix
| Condition | Threshold | Action | Source |
|---|---|---|---|
| Snow on ground | ≥ 3 inches at Village | 4:00 AM CREW CALLOUT | Visual / SNOTEL |
| Freezing level | ≤ 6,100 ft | Snow at Village — monitor closely | Open-Meteo / NWS |
| Wind gusts | ≥ 40 mph | Delay plowing — visibility concern | Open-Meteo / Mesonet |
| Temperature | ≤ 32°F | Watch for ice — salt/sand ready | All sources |
| Precip rate | ≥ 0.5"/hr liquid | Heavy event — all crews standby | NWS / HRRR |
| Snow-to-liquid ratio | 8:1 (wet) to 15:1 (cold) | Adjusts accumulation estimate | Temperature-derived |
