MIT's Nature paper breaks records for 2-6 week weather forecasts with ML error correction

LesterMackey · x · 2026-10-15

MIT News covers a new Nature paper by Lester Mackey and colleagues: a lightweight ML method that learns to correct predictable errors in physics-based and AI weather forecasts over the 2-6 week lead time — a window critical for emergency planning (e.g. events like the 2021 Texas grid failure) — setting new records for subseasonal forecasting. The article traces the team's multi-year progress on this hard problem.
