On Saturday the intense heatwave over south-western Europe will likely bring the earliest 42-43°C in mainland France and maximum temperatures could set some records since they will be around 20°C above the average for mid-June.
In the last few days the most intense heat hit southern Spain, but the strengthening upper High over France will rise temperatures into the low 40s there as well by the next weekend.
With the upper wave sitting over northwestern Iberia, the very warm airmass will easily advect towards France, introducing high temperatures at all levels across the atmosphere.
Both countries could be challenging some historic heat records for the month of June.
The heat dome is strengthening aloft at the same time, leading the heat to quickly intensify.
Temperatures will be higher every day through Sunday, as the High is forecast to be the strongest from Thursday into Saturday over France.
This is likely to be the earliest heatwave of this intensity ever observed since the start of meteorological records in France.
Some of the heat will also reach Germany, Benelux and England later this week and could potentially extend into next week.
The heatwave will likely persist into the next weekend.
On Friday into Saturday, temperatures are expected to be the highest across western and also northwestern France, thanks to the upper High gradually expanding towards western Germany and Benelux.
The national highest temperature record for France in June is an astonishing 46°C in Vérargues (34) on June 28th, 2019.
This heatwave will likely not challenge this record, but low to locally mid-40s are easy to be expected on some of the days.
Especially across the south, southwest and also western France through late this week.
