ERA5 Hindcast — 2026-05-23

Reconstructed from ERA5 reanalysis — not a live forecast rep

This page is built after the fact from ERA5 reanalysis: it shows what the weather actually did along the corridor on this date, not a forecast or analog that was issued at the time. The live daily practice reps (with analog matching and convergence tracking) begin 2026-05-28 — see the Daily Analysis overview. Past-month setup context only; pre-race research, frozen into the build (RRS 41).
