An anticyclone over Scandinavia causes easterly flow across Poland and Germany, converging W-E line across central Germany, Czech Republic and Carpatian mountain range. Weak vertical shear and slow storm motion with moderate MLCAPE will help excessive rain production. Severe wind gusts are most likely across N Germany, Netherlands (MLCAPE 1500-2000 J/kg, but lack of trigger mechanisms) W France, and UK, where Delta-Theta-E reaches 20 K.
