En dat is niet niks!
A limiting factor to tornado risk is the relative stability of the boundary layer, predicted by most models. The highest tornado risk is expected across Belgium, and across the French regions of Normandy, Hauts-de-France, and the western half of Grand-Est, where low-level shear and lapse rates are best. When a tornado develops, the shear supports it becoming strong (>= F2).
