Resolution is based on the Open-Meteo historical/forecast snowfall API for New York City (Central Park / Manhattan center: lat 40.7128, lng -74.0060) for the 7-day window May 31 through June 6, 2026 (local time). The total accumulated snowfall (snowfall_sum field, unit: cm, converted to inches by dividing by 2.54) across all days in that window determines the winning bucket:

• '0 inches' — total snowfall = 0.0 inches (exactly zero)
• '0.1 – 1"' — total > 0.0 and ≤ 1.0 inch
• '1 – 3"' — total > 1.0 and ≤ 3.0 inches
• '3 – 6"' — total > 3.0 and ≤ 6.0 inches
• '6"+' — total > 6.0 inches

Primary source: Open-Meteo daily snowfall_sum aggregated over the 7-day window using the archive endpoint (preferred once dates are past) or forecast endpoint. Secondary corroboration: National Weather Service Central Park official snow report (weather.gov). If the two sources disagree by more than 0.5 inches, the NWS Central Park total prevails.

Deadline: Market resolves after June 6, 2026 end-of-day (11:59 PM ET), once the full window has elapsed and data is final.

Missing / unavailable data: If Open-Meteo returns an error for ≥24 hours past the deadline, the resolver waits up to 48 hours; if still unavailable, escalates to admin review using the NWS source.

Cancellation / impossibility: Not applicable — a snowfall total always exists even if zero. The market will not be voided for weather reasons.

Disputes: Any position holder may dispute within 24 hours of settlement by citing a specific discrepancy in the source data. Admin review is triggered if ≥2 disputes are filed or if the two sources disagree beyond the 0.5-inch tolerance.
