A level 1 was issued for NE-France, Belgium, the Netherlands and extreme NW-Germany for large hail and severe wind gusts.
-------
The general position and strength of the trough/surface depression is not uninteresting in respect of tornadoes as a 20-25m/s speed maximum at mid-levels curves around the base. However, the LL speed maximum is displaced to the west (SW-UK), so LL shear is not strong and initially increases over N-France after sunset, when instability is on the decrease. The main focus for more organized convection is over Belgium, the Netherlands and NW-Germany, as DLS icnreases to 20m/s with SBCAPE in excess of 500 J/kg. Isolated large hail and strong wind gusts are possible with stronger storms. Thunderstorms move offshore during the night hours with a decrease in intensity.
