An Indian Summer is expected next week for most of Europe

Very warm air will spread up across most of the European continent next week bringing a typical Indian Summer, with temperatures reaching the high 20s Celsius or even low 30s Celsius across southwest France and parts of Spain by mid-next week.

🔥 The potential for warm weather is thanks to an increasingly amplifying upper flow pattern upstream over North Atlantic, leading to an upper trough to disrupt to form a cut-off upper low to the west of Europe.
This upper low to the west combined a strong upper ridge building north over Europe looks to pump a plume of very warm air north from Northwest Africa across most of Europe next week.
Temperatures are modelled to reach the high 20s or even low 30s Celsius across southwest France and parts of Spain on Wednesday, as the plume of exceptionally warm air spreads north.

🚩 It seems that the warmest air mass will be across the central parts of the continent, especially over France, Germany, Austria, Switzerland, Italy and the Balkans with even more than 12°C above normal for mid-October.
It will be very mild for this time of the year, with widespread highs above 25 degrees or even higher in Spain, France and Italy.
Very warm also in Germany, Austria and Switzerland with a 2m temperature anomaly of around 8°C.
The new warm spell will likely break many October records by the end of next week.
