A much colder air mass is now spreading across Europe – cold outbreak will intensify across east-central Europe through Monday and Tuesday
A strong cold advection is spreading across Europe this evening, associated with the cold outbreak. The event is intensifying tonight into early this coming week. Long-range model guidance is hinting this might be one of the final cold blasts of such intensity for some time. Hopefully, as this outbreak will again produce damaging frost and […]

*Arctic* After reaching the largest sea ice extent in the past 8 years, the Arctic sea ice is now in an unusually rapid ice melt phase, starting the melt season
Arctic sea ice has reached its maximum extent in early March. The ice melt season has begun, with rapid ice loss, as warmer air reaches the polar regions. Arctic sea ice has reached its seasonal peak at fairly high levels. The maximum sea ice extent was the highest in the past 7 years. The official […]

A severe weather outbreak with very large hail and strong tornadoes possible across Midwest (United States) tonight, March 28th
A significant severe weather outbreak seems possible across far eastern Iowa, northeast Missouri into north-central Illinois and northwest Indiana, United States through late this afternoon/evening hours and tonight. Conditions are merging together for a widespread event, conductive for large to very large hail, severe damaging winds and tornadoes, possibly some strong ones! The pattern over […]
A very strong upper ridge develops a monster high-pressure system over the North Atlantic – near 1055 mbar in its center on Sunday
Contrary to the much above normal activity of North Atlantic troughs and extremely deep surface cyclones over the past few months, the NAO index flips into strongly negative these days. This means the mean sea-level pressure is higher over the North Atlantic than it is further south, usually over the Azores. This weekend, a very […]
Very *high* values of dangerous Particulate Matter (#PM10) air pollutants across Europe this weekend
Like there is not enough stress along with the ongoing COVID-19 virus outbreak this spring, strong cold outbreak across Europe and now the significantly PM10 polluted air making things even worse! Today, the existing pattern over Europe has resulted in extremely high values of Particulate Matter (#PM10) air pollutants across the southern half of Europe. […]
*update* Unusually intense Arctic outbreak will spread across much of Europe through the end of March – additional frost damage is likely
It has been very cold weather across central Europe and the Mediterranean this week, with lots of snow over the Balkans. A new cold outbreak was expected this weekend into western Europe, but now model guidance suggests the Arctic outbreak will be even stronger and spread across much of Europe through the remainder of March […]
Rex block pattern with deep upper low over the Mediterranean brings lots of rain and flooding into southern Italy tonight
A potentially dangerous setup is unfolding across the southern Mediterranean today and tonight. In response to a deepening upper low, a pronounced surface low and frontal system is spreading across southern Italy, resulting in excessive rainfall and flooding threat across Calabria and Sicily region – locally 150-200 mm seems possible until Friday, increasing dangerous flash […]
*Comet show* A newly discovered Comet C/2019 Y4 ATLAS has begun to brighten quickly and could become the brightest comet in the past several years!
The night sky is always full of unknowns and surprises. The latest surprise comes from the newly discovered comet C/2019 Y4 ATLAS. Comet ATLAS was discovered on December 28th, by the Asteroid Terrestrial-impact Last Alert System survey (ATLAS) in Hawaii. This is an astronomical early warning survey system, designed to detect smaller near-Earth objects a […]
March brings a substantial (more than 45 %) drop in global commercial air traffic due to #COVID-19 virus outbreak
Earth can breathe better lately, as global commercial air traffic has seen some substantial decline, followed by the robust restrictions during the Coronavirus / COVID-19 pandemic outbreak around the world. There has been more than a 30% drop in global traffic this month, compared to March 2019. And even sharper decline over the last through […]

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 […]

Winter is back to the Balkans – a huge amount of snow is expected in some areas until Thursday, hurricane-force Bora along the Adriatic coast
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 […]
Spectacular mesovortices within the core of monster North Atlantic cyclone – the system has matured today and is now moving into Iceland
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 widespread cold air mass advection is underway towards central Europe – cold outbreak intensifying tomorrow while spreading into the Mediterranean
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 […]
