Benelux, Germany, Alpine region
Thunderstorms will likely develop/go on during the day ahead of the frontal boundary. Given weak vertical wind shear, pulse storms with isolated large hail and severe wind gusts as well as local flash flooding will be the most significant threat. Late in the period, additional storms are expected to move eastward, while vertical wind shear will gradually increase. A few mesocyclones and multicells may be capable of producing large hail and severe wind gusts, while threat of flash flooding will gradually decrease as storms will move more quickly.
