A level 1 was issued for eastern Romania and central Urkaine mainly for large hail and excessive precipitation.
A level 1 was issued for the southern Baltic States mainly for excessive precipitation.
A level 1 was issued for north-western Russia mainly for large hail.
SYNOPSIS
Two trough centres currently over the Alps and the North Sea will merge to a closed upper low across western central Europe today. This will be associated with weakening synoptic forcing across eastern central Europe today, and the frontal boundary will move eastward behind a frontal wave. Ahead of this frontal wave, warm and moist air masses will remain across south-eastern Scandinavia, whereas relatively dry low-level air masses will affect most of Europe. The cool air mass that dominates Europe is also associated with weak lapse rates due to mid-level subsidence. Steep lapse rates can be found in the wake of the Alps across northern Italy as well as over the high terrain of the Iberian Peninsula and Turkey.
