Presenters Martyn Davies, Sian Lloyd, Chrissie Reidy and Robin Lermitte will in future be based at ITN's Gray's Inn Road headquarters.
The move follows the transfer of ITV's London regional news service from the South Bank to ITN at the beginning of March. The weather service had share studio space and technical facilities with London Today and London Tonight.
ITN takes over the weather service from Wednesday; whilst the move is under way, Monday and Tuesday's forecasts will be recorded at ITV Yorkshire in Leeds.
