EFI and SOT 2 metre temperature over Extended range

Base Time: Thu 29 Apr 2021 00 UTC T+264 Valid time: Mon 03 May 2021 00 UTC - Mon 10 May 2021 00 UTC

EFI index (shading) provides specialized forecast guidance for anomalous or extreme weather events by comparing the ENS forecast with the model climate for the chosen location, time of year and forecast lead time.
The SOT index complements EFI by providing information about how extreme an extreme event might be.

Detailed description of Extended range Extreme forecast index (EFI) and Shift of tails (SOT) products can be found in ECMWF Forecast User Guide.
