The ECMWF CAPE and thunderstorm layers are very different - e.g. massively high CAPE over parts of the UK but not much in the rain/thunder or thunderstorms layers. Does anyone know why these are so different? What goes into the the thunderstorm layer?

Thanks

@ekdyer
CAPE is a measure of instability.
However, instablility on it's own is not enough to ensure thunderstorms.
There needs to be a lifting factor due to orography or frontal activity.
Check for other hints such as high humidity and a forecast of showers in the area.

Yes Rain accumulation is in inches, even if you read 3ft on right hand of the scale.
