As we discussed a week ago, there is an obvious substantial decline in global air traffic, followed by the restrictions and national lockdowns during the Coronavirus / COVID-19 pandemic outbreak around the world. Many countries and airlines have shut down the airports, tens of thousand flights were canceled. At the end of March 2020, there […]

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 […]

As we were expecting, favorable conditions for severe weather outbreak verified across the Midwest yesterday afternoon an evening hours, Saturday March 28th. Several tornadoes have been reported across Iowa, Arkansas, and Illinois, severe storms with damaging winds across the Tennessee valley.

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 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 […]

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 […]

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. […]

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 […]

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 […]

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 […]

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 […]
