DISCUSSION: As strong storms impacted many parts of western and northwestern Europe over the past couple of days, some areas saw especially impressive deep convective storms. However, some areas within countries such as France and across parts of southern Germany were impacted quite dramatically with deep convective storms. Moreover, a few of these storms encountered substantial amounts of deep layer vertical wind shear which facilitated deep layer rotation with some of these severe thunderstorms which erupted. As you can see in the raw footage attached above, one particular thunderstorm which erupted over parts of far northern France!
In addition, as you watch the aforementioned footage of this impressive supercell thunderstorm (i.e., a severe thunderstorm which has a rotating updraft that is sometimes capable of producing a tornado), you can even see the primary inflow sector of the supercell thunderstorm. This inflow sector is defined by what appeared to be "rising clouds" on the bottom right-hand portion of the cloud base which was the wall cloud associated with this supercell thunderstorm. A wall cloud is defined as the lowering of the cloud base within the supercell thunderstorm and is most often the location within a supercell thunderstorm where a tornado typically forms.
