A level 1 was issued for SE Spain, NE Algeria and Tunisia for large hail and to a lesser extent for severe wind gusts.


Weak geopotential gradients dominate across most of Europe. An upper-level trough extends from the Baltics across the Alps into Northern Spain and slowly moves southeastward, gradually merging with a stationary upper-level low centered over Eastern Bulgaria and Romania. These areas experience unsettled and moderately warm conditions. High pressure brings stabilization and rising temperatures from the Bay of Biscay into France, BeNeLux and Northern Germany.
Further North, a meandering polar jet runs across the Northern Atlantic and Scandinavia. The occluding frontal system of a strong cyclone centered near Iceland crosses Norway and the British Isles, but deep convection is not expected.
