Race-morning weather history
Mid-April Richmond: mild spring mornings (~45–65F), variable — typical-climate characterization, UNVERIFIED; ERA5 supplies actuals. 2020 and 2021 editions were disrupted by COVID (virtual/no standard in-person race) — flag; not included as normal April slots. Because the specific Saturday drifts, use the hand dates, not a computed nth-weekday. 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.
