We are just seeing a pretty strong outbreak of cold air mass into east-central Europe this week, there is more coming soon! It appears likely another *very* powerful ridge/high-pressure system will form over North Atlantic and introduce a significant cold outbreak into western and potentially also southwestern Europe through the final days of March. Even […]

A strong cold outbreak is underway across the east-central Europe and the Balkans this week, in response to a very powerful upper ridge and 1040+ mbar high-pressure system over northern half of Europe. The pattern also introduces a snowfall event over the Balkans where a deep upper low will maintain over the western part of […]

A very large North Atlantic depression has peaked today. It reached 953 mbar with the rapid intensification completed on Sunday morning. It, yet again, delivered a spectacular satellite presentation of the cyclone’s core, also with very interesting features in the evening hours – several mesovortices within its large core. The system is now moving across […]

A powerful high-pressure system is dominating much of Europe today, centered over the Baltic region. With northeasterly winds along the southeastern flank of the ridge, a much colder air mass is now underway across the Balkans and central Europe. A developing cold outbreak intensifies tonight as the upper low aloft deepens. The much colder air […]

The post A widespread cold air mass advection is underway towards central Europe – cold outbreak intensifying tomorrow while spreading into the Mediterranean appeared first on Severe Weather Europe.

As the world continues the fight against the COVID-19 pandemic, we are starting to observe first potential effects on the climate system. The CO2 levels have currently paused the seasonal increase, likely due to the slowdown of the industry in China and the rest of the countries that are dealing with the outbreak of the […]

A damaging earthquake hit the Croatian capital Zagreb this morning, March 22nd at 05:24 UTC (6:24 local time). Its magnitude was 5.3 by the EMS-98 scale, several aftershocks were followed later. Earthquake did a significant damage across the city of Zagreb, with severly damaged cars and houses. Several people were injured, at least one critical. […]

It’s been about a week since the last deep cyclone over the North Atlantic, as strong ridge developed over the last days. To the west of the ridge, a very powerful frontal system and deep extratropical cyclone have developed today, over the Northwest Atlantic and the southern Labrador Sea. Rapid intensification is now underway, developing […]

The new data analysis by the Copernicus Sentinel-5P satellite reveals significant changes in the air pollution across China. Data analysis between late December and mid-March shows a significant decline in nitrogen dioxide (NO2) emissions during China’s national lockdown in January and February, followed by an increase of air pollution once the national lockdown is canceled […]

All models are in very good agreement we will be facing a powerful and very dangerous cold outbreak from Sunday through Thursday. An advection of extremely cold late March temperatures will spread across east-central Europe and the Balkans first, then also reaching the Mediterranean and western and southwestern Europe. There is a *high risk* for […]

Daylight is slowly expanding towards the Polar region as we’re going further into spring. This means we can observe some pretty spectacular imagery on the Arctic region sea ice extent we couldn’t see weeks ago during the polar night. Over the last few weeks, some clear days finally opened the skies so we can see […]

Both European and American continents are ahead of a significant pattern change this week. Similar to Europe, an Arctic outbreak is expected to spread across a large part of the United States after today, with an extensive high-pressure system expanding from Canada. Temperatures will fall below 20 °F across the northern half of the US, […]

A large part of Europe is facing a very warm period this week, as a strong Omega blocking pattern has established. But a significant pattern change is coming up this weekend, NAO (Noth Atlantic Oscillation) turns into a negative phase. This means a strong upper-level ridge will develop over the Atlantic and expanding into Europe […]

The post Rex block pattern develops a dangerous Arctic outbreak across east-central Europe after Sunday – much colder weather is expected appeared first on Severe Weather Europe.

It is a rather rare occurrence to see a larger area of sustained ozone depletion over the Arctic regions during the late winter/early spring season. But this year, records were broken, as an unusually large area of ozone depletion has formed. We have all heard of ozone before. More likely in the context of the […]

An extensive upper-level Omega blocking pattern is establishing across a large part of Europe this week. It will bring spring-like weather across the east and central Europe, partly also over southern Europe. Afternoon temperatures will locally exceed 20 °C. Cold weather develops over UK and Ireland, persisting over Turkey as well. An Omega blocking pattern […]

Tropical Cyclone #Herold has maintained its 75-80 knots intensity today, while the central pressure is around 972 mbar. It is moving southeast now with an accelerating rate and expected to affect both Mauritius and Rodrigues islands. Its track tomorrow will be very near Rodrigues island, so a potentially dangerous situation could evolve over the island. […]
