After a long period of high pressure conditions and mostly dry weather over the western Europe, the weather pattern over our continent changes at least for a while.
During the period between 20/1 and 25/1/2019, the Azores anticyclone is going to be restricted over its original position (Azores islands). For this reason, at the beginning of this period we should expect an extensive low pressure system over northwest Europe with a short snow episode mostly over Iceland, Scotland and northern England. Cold weather will dominate over central and eastern countries with some mainly light snow in coastal areas of Scandinavia, eastern Europe and northern Balkans. This cold air mass, then, will move south-westwards combined with a deep low pressure system affecting regions of France, Iberia and Italy and Alps with snow in northern regions and rainfalls in southern regions. Heavy snowfalls may occur over Iberian, Moroccan and Algerian mountains. The weather will remain milder in southeastern Europe with southerlies, rainfalls in western and southern coasts and a possibility for African dust transportation.
