Intense severe thunderstorms in eastern France, Luxembourg and Germany last night – August 1, 2017
Widespread severe thunderstorms hit eastern France, parts of BeNeLux and western Germany last night and this morning (July 31/August 1).
A volatile setup over central-eastern France and central Germany yesterday produced widespread severe thunderstorms over the region. An unstable atmosphere, with moderate to high instability with MLCAPE in 1000-2000 J/kg range, overspread by a strong mid-level jetstream, to produce about 40-50 kt deep-layer shear; an environment conductive for formation of intense supercell thunderstorms.
Intense discrete thunderstorms, including supercells formed across W-CNTRL-E France. One particularly intense supercell tracked east of Reims. The supercell certainly produced significant hail, we are still gathering reports.
In the morning hours, severe thunderstorms with intense damaging straight line winds and large to very large hail hit the vicinity of Frankfurt, W Germany. Jonas Piontek of Gewitterjagd provided live coverage of the storm.
