After 18z dangerous conditions set up in southern France where one or two MCSs or a supercell will form with excessive rain being the main threat near Massif Central mountains. Very humid air masses (mixing ratio >15g/kg) move onshore and result in high MLCAPE values with DLS exceeding the 20m/s. Moreover, rotation of these features will be pronounced as SREH 0-3km calculated by NWP models, will be in the range of 200-400m²/s². The aforementioned areas are expected to receive even up to 200mm of rain in 24h so flash floods are certain.
