Supercells with marginally severe hail in central France in the night of October 20, 2013
Several marginally severe supercell thunderstorms hit central France in the early morning hours of October 20, 2013. Storms produced marginally severe hail (hailstones 2-3 cm in diameter) and accumulations of over 10 cm of hail have been reported from the area. The thunderstorms formed in a fairly low CAPE, but high shear environment. An interesting, more detailed report with detailed analysis has been made by Keraunos.org.
