A level 1 was issued for S Italy, Albania and W Greece for large hail and severe wind gusts.
A level 2 was issued for Macedonia, N Greece and parts of Bulgaria for large hail, severe wind gusts and excessive precipitation.
A level 1 was issued for the rest of Bulgaria and NW Turkey for large hail, severe wind gusts and excessive precipitation.
A level 1 was issued for parts of Moldova, the Ukraine, Belarus and Russia for large hail and excessive precipitation.
SYNOPSIS
An aged long-wave trough extends from Norway to Italy and slowly moves eastward. Two jet streaks dig from the Northern Atlantic into Denmark and from France into the Central Mediterranean, respectively. Geopotential falls in their left exit regions keep the long-wave trough still in shape during the forecast period, though it otherwise starts to disintegrate due to increasing QG subsidence ahead of pronounced ridging from Iberia to the British Isles.
At lower levels, cyclogeneses occur under the mentioned left exit regions over Southern Sweden and (less defined) over Macedonia. A Northwesterly flow advects cool and mostly stably stratified maritime air into Central Europe and the Central Mediterranean, before conditions start to warm and to clear over Southwestern Europe.
Further downstream, a rather diffuse cold front continues its slow eastward motion over Eastern Europe. Very warm and relatively moist air still advects North ahead of it over the Eastern Ukraine, Russia and Finnland.
