DISCUSSION
NW and N Germany, E Denmark...
Although a number of strong storms are ongoing, including a number that contain weakly rotating updrafts, a major severe weather day appears not to materialize. Most likely this is due to a combination of weak instability and the fact that vertical wind shear is mostly located within the boundary layer and above 4 km AGL but shear is weak in between. We will retain the level 1 threat area as an isolated tornado appears still possible as well as some localized large hail and strong gusts.
