A level 1 was issued for northern Tunisia, central and southern Italy, Adriatic and northern Ionian Sea, northern Greece and southern Balkans into Bulgaria, Romania and Moldova mainly for large hail and severe wind gusts.

Atlantic high continues without a weakening tendency. Arctic air masses will spread into Scandinavia and western Russia at the eastern flank of this high. Polar air masses that have spread into most of Europe will warm in response to diurnal heating, and slightly decreasing moisture and lapse rates can be observed to the south-west of a new cold front that enters the Ukraine, Poland, and eastern Germany in the afternoon and evening hours. A few storms can develop especially below the axis of the long-wave trough from Germany across the Alps, southern France, into eastern Iberia.
Ahead of the long-wave trough, a west-south-westerly flow will establish from northern Tunisia to the Aegean and Black Sea region. An elevated mixed layer will spread into the east Mediterranean, affecting the Ionian and Aegean Sea. Weak frontogenesis to the south of Italy will additionally allow for moisture increase in the boundary-layer, but the capping inversion is forecast to remain quite strong.
