Severe Weather Europe
The Arctic outbreak has verified yesterday and continues this morning. Very cold temperatures are spread behind the cold front and have resulted in morning temperatures several °C below zero over Germany, part of Benelux, and also over the UK and Ireland. It is also snowing in northeast Europe. A few more very cold days are […]
East tropical Pacific ocean starts to cool, initiating a cold ENSO phase! It will boost the hurricane season and affect the winter 2020/2021
The global weather system is constantly in motion. It is always trying to reach a global balance, or equilibrium, which it can never achieve. One such attempt of global balance is starting to appear in the eastern tropical Pacific Ocean (ENSO), where an ocean surface cooling trend is starting to appear. It indicates a regime […]
The cold air mass pool associated with the arctic outbreak is racing towards central and eastern Europe tonight. South of the deep trough and main cold front, a frontal system should bring excessive rainfall and severe storms threat over France and the Alps tonight. Much colder weather will spread behind the front, likely 15-20 °C […]

The tropical activity is ramping up in the western Pacific this weekend. A tropical wave #95W begins forming deeper and more widespread convection in the Philippine Sea. A tropical depression #Ambo has formed along the eastern Phillipines. It is expected to strengthen further over the next few days while heading west into the northern Philippines. […]
*update* on the powerful cold blast across west-central Europe through Sunday and Monday, May 10-11th
Here is the follow-up update post on the developing sharp pattern change and soon a return of cold weather for a few days. The famous Ice Saints – St. Mamertus (or St. Boniface), St. Pancras and St. Servatius start on Monday. This year, they bring us a cold outbreak into many parts of Europe. An […]
We have discussed about the direct effect of the national lockdowns due to coronavirus weeks ago, a remarkable decline in global flights was observed. The total flights globally were down by 62% in April, compared to 2019. Commercial air traffic was down by even more – 74% lower than last April! In April 2020, Flightradar24 […]
In parts of the Northern Hemisphere, the period from May 10th and 15th is often believed to bring a brief spell of colder weather in many years through the past centuries. These are often reports of a marked cold snap over the days of the Ice Saints (May 11-13th). It seems that we will face […]
The Spanish heatwave has verified across the Iberian peninsula this weekend, as a large omega blocking pattern has established and is resulting in a significant warm advection into southwestern Europe. Many weather stations reported mid 30s peak afternoon temperatures yesterday, Sunday, May 3rd. It was 33-35 °C in parts of Portugal and up to +36 […]

Some changes in the pattern over the southern and western part of Europe in coming in early May. An omega blocking pattern should develop and support a significant warm advection into southwestern Europe, resulting in a very hot air mass also in the lowlands. It is likely the daytime temperatures will push into the mid-30s […]
Early May forecast, starts the month with an unseasonal cross-polar flow pattern into North America, and a ridge divides Europe into two temperature poles
This spring is really interesting as far as weather patterns go. Winter featured more spring-like patterns. But as soon winter was over, the Northern Hemisphere spring has shifted into more winter-type patterns. Early May forecast features a cross-polar flow pattern into North America, which is much more typical for winter months. April ends… The […]

We have a new record in the tropics. It’s late April but Eastern Pacific already got its first system today – Tropical Depression One-E is the earliest eastern Pacific cyclone on record. It is packing winds of 30 knots, central pressure around 1006 mbar. Although it stays away from any land areas, it is remarkable […]

April 2020 temperatures across the Gulf Coast states from South Texas across southern Louisiana to South Florida are exceptional! The summertime-like temperatures and record warmth of the Gulf of Mexico. Numerous cities are smashing the all-time heat and average records. The blocking pattern and persistent high-pressure systems across the Gulf and southeast US have contributed […]
Hurricane season 2020: Above-average number of tropical storms, 10 hurricanes where 3-5 of them could become major hurricanes
Based on the various factors as Atlantic Ocean sea-surface temperatures (SSTs), ENSO (neutral conditions with potentially developing towards La Nina) and correlation with similar atmospheric conditions in the past hurricane seasons, we can expect the 2020 Atlantic hurricane season to be more active than usual. Possibly similar to 2010, 2011, and 2017 seasons. According to […]
Excellent observing conditions for tonight’s #Lyrids meteor shower over EU and USA, Apr 21st / Apr 22nd
The annual Lyrids meteor shower peaks tonight, so many of us will be out under the skies observing this fine celestial show. Weather permitting, of course. Also, there will be no Moon to disturb the dark night. There are great chances for many observers across both continents. So, let us take a look across Europe […]
The ongoing progressive pattern over southern Europe and the Mediterranean against the extensive and powerful upper ridge over northern Europe and Arctic region, will result in reversed flow in between. This flow is favoring an advection of Saharan dust load from the the North Africa into the Mediterranean, central Europe and now also towards France, […]
Europe is meteorologically divided into two regions this week; to an extensive upper ridge across the northern parts of Europe and a progressive dynamic pattern across the southern parts – upper lows moving across Iberia and Mediterranean. This evening, a spectacular satellite presentation is visible of both upper lows. Systems will bring excessive rainfall threat […]

A very powerful upper ridge and strong warm air mass advection into far North Atlantic and Greenland until Thursday
In our other update, we have shared a discussion about an extraordinary ‘heatwave’ into the Arctic region this week. Now, let’s take a look into more details on the temperature and geopotential height anomalies across the far North Atlantic, Greenland and Scandinavia, as a very powerful upper-level ridge and a surface high-pressure system establishes this […]
An extraordinary “heatwave” will enter the Arctic region, raising temperatures more than 20°C above the long-term average, pushing out the colder air into Canada!
Strong airmass changes across the North Hemisphere continue, as patterns change on the shift from winter to summer. Strong pressure differences over the polar regions, will send a remarkable “heatwave” into the North Pole. This year, the transitional period between winter and summer (we call it spring) is very dynamic. We have already seen continents […]
