.... N Germany, the Netherlands and NE Belgium ....
The cold air masses near the core of the trough will be enhanced with moisture over the North Sea and combined with steep mid-level lapse rates will result in a few hundreds of CAPE. Large hail is low but still possible, as well as local convective wind gusts.
