A level 1 was issued across Netherlands and N Germany mainly for tornadoes.
DISCUSSION
A combination of a broad belt of strong southwesterly flow, a wavy frontal boundary, and abundant lower tropospheric moisture ahead and south of the boundary will result in an unusually large area of potential severe weather. This area will extend from Spain into Ukraine and Belarus with the highest severe weather risk from the Balearic Sea to N Italy.
... Netherlands to N Germany ...
A combination of a low LCL environment, substantial 0-3 km CAPE, and 0-1 km shear around 10 m/s points to an elevated tornado threat with supercells that may form given 15 to 20 m/s of 0-6 km bulk shear.
