Days will be gradually colder from today onwards, at least until Tuesday.Ī frontal system with a winter storm will develop across the northern Mediterranean and central Europe. Thus maintaining cold weather for several days. The strong High over the northern Atlantic will be powerful enough to block the zonal flow so that the air masses will be blowing from the north for quite some time. While lower pressure will gradually establish over most of Europe this weekend. First, days will become much colder over northern and western Europe, gradually also over central Europe.Ī large and deep upper-level trough will develop, completely dominating the weather across Europe for several days.Īt the surface, very high pressure will maintain over the far North Atlantic, connecting with the High over Greenland and the Arctic region. A STRONG LOCKED-IN PATTERN DEVELOPS OVER EUROPE THIS WEEKEND, PERSISTING INTO NEXT WEEKĪs the weekend starts, the upper-level ridge over the far North Atlantic and the Arctic will help to develop a channeling flow of significantly colder air toward Europe. Therefore, frontal systems will develop and help to intensify the advection of cold air mass into western and central Europe in their wake. This will increase the wind flow in between the colliding colder air from the north and much warmer from the south. Thanks to the deepening upper levels as mentioned above. While we can see the low and its core relatively small today, it will become much larger as we head into the weekend. The arrival of a much colder Arctic air mass into the region will deepen the upper trough, allowing cold temperatures to spread farther south and also into the lowlands. This is the start of the most significant Arctic cold blast this winter season 2022/23. To the north, we can see a large pool of much colder weather developing over Scandinavia and the North Sea. This sends a much warmer and very moist air mass from the Mediterranean towards the east-northeast. POWERFUL BLOCKING HIGH OVER THE ARCTIC, PUSHES DEEP TROUGHS AND COLD BLASTS TOWARD EUROPEĪnalysis of the satellite imagery across Europe and the North Atlantic paints an interesting picture with a strong zonal flow established across the southern portions of the European continent. Let’s now dig into details to see how the cold blast will take its steps over Europe. The next days, possibly even extending into late next week, will see pretty cold mid-December weather, which should bring winter storms, snow, local blizzards, and significant amounts of rain with flooding for parts of the Mediterranean region. We can clearly see how a huge reservoir of much colder-than-normal air mass is forecast to spread into Europe, sending countries into the coldest days for the winter season so far. The evolution of the progressive weather pattern dynamics is best represented in the video animation below. This will result after a strong upper High sitting over the Arctic region, sending a major cold outbreak far toward the south. What we will discuss in detail below is the development of a persistent and progressive weather pattern, with a huge pool of very cold air mass coming up for a large part of the European continent. Potential is also increasing for some good amounts of snow across a large part of central and partly western Europe later next week. Temperatures will be significantly lower than normal, the coldest for this winter season so far.Ī lot of snow is forecast for the Alps while flooding rain farther south as several frontal systems will cross the European continent. Starting tonight, an Arctic cold blast will begin spreading from north to south into the UK and Ireland first, gradually overspreading the rest of western and also central Europe for the weekend. The situation across Europe this week is supported by a dipole weather pattern, with low pressure over the Atlantic and western Europe and more stable weather farther east and south.
