A multicore low pressure system is situated over France, Germany and northern Italy. Cool airmass has entered France and the northwestern Mediterranean. Warm unstable airmass is sticking around Italy and the western Balkan, as well as in a small pocket over eastern Spain. An occluded front with weak conditional instability stretches from the Alps to the Netherlands. From Czechia to Moldova it has the form of a warm front. A merry-go-round of shortwave upper troughs affect Netherlands, western France, northern Italy and Hungary. An occlusion of another low with a zone of unstable air is present over western Russia. Northern Africa is also active and very high-based. Model buoyancy profiles look weak in the mixed phase region over France, Germany, Romania and Russia, with reduced potential for significant electrification and hail production.
