Race-morning weather history
Early-January central Florida is the coldest WDW race slot: morning starts commonly ~45–55 °F but with real cold-snap tails — UNVERIFIED climatology. 2021 in-person race CANCELLED → virtual only (COVID); flag as no in-person race. Floating recurrence, so no auto slot-backfill — history rides the hand-listed Saturdays. Wyndo tracks what past editions of the race actually served up at the start hour — temperature, dew point, wind, and rain, and reads the live forecast for the start once the race confirms its schedule and race week arrives.
