 "limits": [
  "The summer quarter is a hypothesis-testing window, not a date assigned to the picture. Foliage does not rule out late spring or early autumn.",
  "Ranks exclude every incomplete window and are not homogenized for gauge changes. Nearby gauges are never pooled.",
  "Rain days use station observation dates; GSOD thunder uses UTC dates. Aligned chart dates do not establish the same storm.",
  "GSOD zero means no or not reported. Modern thunder counts are reported occurrences, not a homogeneous thunderstorm climatology.",
  "The airport comparison uses all 30 matching windows in 1991–2020, calculated from daily data; it is not an official NOAA normal or a Lake Eden anomaly."
