A level 2 and a level 1 were issued for SE Italy, S Adriatic Sea, SW Balkan mainly for excessive convective precipitation, large hail, and tornadoes.
A level 1 was issued for S Germany and the northern Alpine region mainly for excessive convective precipitation.
A level 1 was issued for N Scandinavia mainly for large hail.
A level 1 was issued for N Catalonia mainly for large hail.


Slight low pressure prevails from N Scandinavia into central Europe and Balkan, with steep lapse rates and sufficient moisture to create weakly capped MLCAPE of 500-1500 J/kg. Vertical shear and deep lifting will be weak or absent over a large part of this area. However, two upper/mid level lows are found on the map. One moves from Scotland toward northern France with the potential of destabilizing the Benelux, S UK and NW France at night. The other low moves from Italy into southern Balkan and is causing active thunderstorms over a large area and enhanced deep layer shear.
