Meanwhile GFS still suggesting that Thursday could be the second hottest day on record, with 39C (and Friday also possibly pushing June 26 out of the top 5). If that were to happen then 2026 would have 3 of the top 6 hottest days ever, and 4 of the top 10 (including ties).
Arpege only goes for 35C max though, quite a big difference at this stage.
