Severe thunderstorms in the north and central Mediterranean

Severe thunderstorms are expected across parts of the northern and central Mediterranean. Expect strong overlap of deep-layer shear (30-50 kt) and moderate to extreme instability (1000-3000+ J/kg MLCAPE), producing an environment that will be highly favourable for severe thunderstorms. Expect torrential convective and orographic rainfall in NE Italy, W Slovenia and W Croatia. Detailed forecast coming tomorrow.

Snow in the northern Alps
