Χιόνια σημειώθηκαν χθες (Δευτέρα 5/4/2021) σε πεδινά της κεντρικής Ευρώπης. Δείτε videos από Αγγλία, Γερμανία, Ολλανδία, Δανία, Βέλγιο και Ελβετία.

 

Το αναμενόμενο κύμα ψύχους, για το οποίο είχαμε μιλήσει 4 μέρες νωρίτερα (δείτε εδώ Απρίλης: Η προσπάθεια της άνοιξης να διώξει τον χειμώνα) έφτασε στην Ευρώπη και έφερε μαζί του κρύο και χιόνια ακόμα και σε μεγάλες πεδινές πόλεις. Πολλά videos κάνουν τον γύρω του διαδικτύου από χθες, καθώς πολλές περιοχές ντύθηκαν στα λευκά, κι ας έδειχναν τα ημερολόγια 5 Απριλίου.

Η θερμοκρασία σε πολλές ακόμα και πεδινές περιοχές έπεσε κοντά στους 0°C στη Σκωτία, τις κάτω χώρες και τα βόρεια της Γερμανίας. Πάμε να δούμε όμως videos από Ηνωμένο Βασίλειο, Βέλγιο,

 

Ξεκινάμε με Ελβετία και το προάστιο Witikon της Ζυρίχης, όπου ο Γιάννης Καθαρόπουλος ξαγρύπνησε να βλέπει για πολλοστή φορά φέτος ισχυρή χιονόπτωση να ασπρίζει το μπακόνι του:

 

Χιονοπτώσεις στην βορειοανατολική Αγγλία και την Σκωτία, χιονοχάλαζο στο Λονδίνο:

 

Χιονοκαταιγίδα στις Βρυξέλλες ασπρίζει τα πάντα σε λίγα λεπτά:

 

Ισχυρό χιονοχάλαζο στην Κοπεγχάγη:

 

Και στο Άμστερνταμ σημειώθηκε ισχυρή χιονόπτωση για κάποια ώρα ασπρίζοντας πρόσκαιρα κάποιες επιφάνειες:

 

Η πρωτεύουσα της Γερμανίας, και αυτή στα λευκά:

Summing up this winter weather so far

This winter may be characterised by the absence of intense anticyclonic fields over Europe, extensive low pressure systems from the Atlantic and in average mild weather over the major part of Europe. Although there was a fairly short period of cold spells and snowfalls from north to the south in January, snow and low temperatures were mainly observed in limited higher ground areas.

 

The beast from the east

So, as cold air will start spreading out gradually from tomorrow (6/2/2021) over Siberia and Scandinavia, a shallow field of anticyclonic pressure will form over such regions preventing the low pressure systems over the Atlantic to move along a very northern track towards Europe. Thus, a field of strong easterlies will be established over the North Sea, which will be moisturised and will bring severe snowfalls along the east coast of the UK the period 7-11/2/2021.

 

What’s next?

The formation of a family of low pressure systems over the Atlantic moving towards Europe seems to be preserved till 11/2/2021. Then, there are hints showing that the depressions over the Atlantic will obtain a fairly meridional shape and orientation pushing the Azores anticyclone to move northwards, pushing then the significantly cold air masses from eastern Europe to move to the south. This means that the weather over the western Europe should gradually be settled with dry spells, and the winter comes back to the eastern parts of Europe and the Mediterranean Sea. However, it is a question how east or west, this anticyclone will “decide” to move to the north. This certainly affects the way and the regions that will face a severe aspect of winter.

 

 

Conclusions

The winter is coming back firstly in the northwest of Europe and the UK with quite cold conditions and snow. However, for the rest of the month it seems that anticyclonic conditions will be established gradually over central/north Europe. This will lead to wintry weather in the south and east and dry weather over the central/northern Europe.

November is typically a wet month, when weather and atmospheric depressions start to activate. However, this will not happen this year. Let’s have a look at Europe’s weather in this November.

 

This dry begining of November seems to remain for most of the current month for the major part of Europe. An extensive anticyclone is covering and will be covering central and northern parts of Europe for at least the next fortnight blocking any weather activity. In the meanwhile a low pressure system over the North Atlantic Ocean will be trying to advect some moisture over the very west parts of Europe (UK, Portugal, western Spain, western France) causing some occasional rain, but that’s all. Definitely, we expect foggy and frosty mornings at places far from the sea for most of central and eastern parts of Europe. It is highlighted that temperature will gradually drop in eastern Europe, while the weather will be active only around the eastern Mediterranean Sea. At this region, we expect some rain and snow over hills/mountains (>800-11000 metres of altitude in average).

 

Looking further to the future, this circulation pattern seems to stay for longer. Although the low pressure system over the North Atlantic Ocean will tend to enhance, will be blocked there till 20/11/2020 affecting only the very west parts of Europe. Anticyclonic fields will be preserved over north and southwestern Europe making the weather fairly dry for the season, while again the only weather activity will be possibly observed in southeastern Europe, which will be affected by russian cold air masses.

It should be noted that this is a brief discussion of what we see in the forecasting models today. Weather trends may change as we move towards the second half of this month.

The weather seems to remain unsettled for the most of Europe the next ten days of June. Watch how this unsettled weather will be distributed over our continent.

In particular, for the period 10-20/6/2020:

1. The rise of the Azores anticyclone with a final destination over Anticyclone is expected to cause the formation of a new low pressure system over the northwest of Europe. This weather system will be followed by consecutive rain bands and zones of strong winds at times and places in the UK and France, while the temperature will remain around or below the average. In contrast, Scandinavia will face fairly warm and dry conditions with temperature much above the average.

2. At the same time, colder air masses will slide to the southwest from Russia affecting the Balkans, Switzerland, Italy, and Iberia with convective weather mostly in the afternoon. The temperature in all these regions will be fluctuating around the average.

3. No heat wave is expected this period over Europe. The only exception is some possibility for short periods of occasionally warm weather in Iberia.

4. From the regions mentioned in 2, the Balkans (till northern Greece, the southern of Germany and Switzerland appear to be highly likely to be affected by heavy thunderstorms at times.

 

The current article is just an estimation of the possible average situation over Europe the period 10-20/6/2020 over Europe.

 

Snowfalls, heavy at places, occurred last Thursday (27/2/2020) over region of north and central Europe. Watch the videos found on youtube!

A short passage of snowfalls observed last Thursday (27/2/2020) in north and central Europe. Let’s watch some videos uploaded on youtube by weather fans!

 

Let’s start from Scotland:

 

 

Next stop is Yorkshire in NE England:

 

Going down to the Midlands of England. Snow fell even in places of northern London. The next two videos come from Bedford and Luton:

 

Finally, heavy snow occurred in regions of Germany. The following videos are from Munich:

This autumn is characterised by a very rainy beginning for the northwest of Europe and a dry one of southern regions. Is it going to change? So so… Let’s have a detailed look!

 

The synoptic conditions: The Azores anticyclone presents a trend to move northwards pushing some cold air southwards to the southeast of Europe. Depending on the movement of this anticyclone, this cold air mass may reach the Adriatic sea causing cyclogenesis. The possible low pressure system will affect southeast Europe with heavy rain and some snow over mount tops.

 

The UK: It will remain unstable with periods of heavy rain and strong winds especially in the central and north regions, but also some dry spells. The temperature will remain around average.

Scandinavia: It will turn into rainy with strong winds over the southern regions. In the north it will be a bit drier with some rain at times and possibilities for snow over hills and mountains. The temperature will drop significantly especially in the central and northern parts.

Iberia: No rain at all. Mild in the northern, with some heat air pushing from the south. Hotter in the south with an episode of heat wave.

The central Europe: A transitional zone of unsettled weather at the beginning with some rainfalls and some snow over eastern mountains. It will turn into drier for the rest of this region except for German and northeast of this region (countries close to Russia) with some rain episodes. Significant snow may occur over the Alps. West Italy is included in this zone.

The southeast corner: If the cyclogenesis we talked about takes place, the weather will significantly change with heavy rain in the west coast of Balkans and the southern places. Snow may be observed over northern mountain tops. The rest of Balkans will be affected by rain too, however this storm will focus on the places noted before. East Italy may be included.

Significant weather change is expected in eastern Europe gradually the next days and especially from 10/7/2019 and then with temperature drop and afternoon thunderstorms. In contrast, a new heat wave may affect parts of Iberia and south France.

In particular, part of cold air masses over Scandinavia and Russia will move southwards affecting central/eastern Europe (from Germany to Switzerland to Greece and Turkey) causing unsettled conditions with severe thunderstorms (increased possibilities for hailstorms) during afternoon/evening). In addition, the temperature will significantly drop to levels around or below average after a prolonged period of increased temperatures. As an exception, central/south Aegean and western Turkey will face dry and windy conditions (NE winds).

The cold air masses will remain over northeastern Europe, being dissipated, causing unsettled conditions with rainfalls at times and possibly strong winds at places. The temperatures will remain around or below average.

Unsettled conditions with (mostly) afternoon/evening thunderstorms may occur in northern Iberia with temperatures around average. In contrast, dry and warm conditions (with a possible heat wave) are expected in central/southern Iberia and southern France with temperatures >38°C.

Finally, in northwest Europe, the weather will remain within the climatological limits with periods of rain and sunny spells.

Europe may face extreme weather conditions and differences from places to places the last week (24-30/6/2019) of this June with a heat wave and heavy thunderstorms.

In particular, we expect a significant heat wave, which will affect Spain, Portugal, France, Germany, eastern/southern of England, Italy and Benelux with temperatures that may reach 34-36°C. However, the temperature may exceed 38-40°C at continental places of northwest Africa, central/eastern Spain and southern/central France. At this places dust advection will take place, but this will not be an extreme episode.

The weather will remain stormy with rain episodes at times in Ireland and western/northern UK. However, some storms may affect the UK as a whole at the end of this period.

For the rest of northern countries the weather is expected around normal with some rain episodes and temperatures around the average.

Unsettled conditions will possibly occur in central/eastern Balkans, continental eastern Europe and southern Alps/north Italy with thunderstorms mainly around afternoons and evenings. The temperatures will fluctuate around normal or below.

Etesians (north east winds) will settle over eastern Greece (Aegean) and western Turkey reaching up to 60km/h over seas some days in this period.

EUROPE WEATHER OVERVIEW MAP MAY

The weather is going to change dramatically the upcoming week in central and mainly eastern Europe from Sunday (12/5/2019) presenting autumnal traits.

 

In particular, from Sunday and then, the Azores anticyclone will be gradually developed and established in western Europe with a centre over the UK. This will result in better (fair and dry) weather conditions in western Europe with hot for the season temperatures over south and west Iberia (up to 35-37°C).

This situation will push colder arctic air masses to invade north and eastern Europe. Snow will occur in north-central Scandinavia even on lower ground regions, while some snow may be observed over hills/mounts in the northern regions of central/eastern Europe (such as eastern Germany, Poland etc).

Next, the majority of eastern Europe, from Italy and further to the east, will be affected by stormy and colder than average weather with rain at times and afternoon thunderstorms mostly in central and western regions. The most severe weather, where hailstorms may occur, is expected in eastern Italy, western Balkans and possibly regions of northeastern Balkans far from the sea.

The weather will remain fair, dry and hot in Cyprus and eastern Turkey.

 

The weather may completely be reversed from 18/5/2019 and then with a possible heat wave in southeastern Europe and rainy weather for the western.

(CNN) – Firefighters have contained a blaze that erupted on moorland in West Yorkshire in northern England, one of the three wildfires that broke out across the United Kingdom as temperatures hit record seasonal highs.

The fire, on Saddleworth Moor, burned throughout Tuesday night across about 1.5 square kilometers (370 acres) near the village of Marsden. Orange fire-line streaks and haze illuminated the dark sky.
“The fire now looks to be out,” the fire service’s official Twitter account tweeted Wednesday morning, adding that “5 pumps and 2 wildfire units are still at the scene and will remain there for much of the day to tackle any further hot spots.”

Other fires broke out in Edinburgh, on the city’s famed Arthur’s Seat hill, and in the southern English county of West Sussex, in woodland immortalized by A.A. Milne’s Winnie the Pooh stories.
The West Sussex Fire and Rescue Service blamed the “unusual warm weather this week in Sussex.”

Warmest winter day recorded

Temperatures in parts of the UK reached 20 degrees Celsius (68 degrees Fahrenheit) for “the first time in winter on record,” Britain’s national weather service, the Met Office, told CNN.

A countrywide record for the warmest winter day was set Tuesday for the second day in a row, with Kew Gardens in London hitting 21.2 degrees Celsius (70.16 degrees Fahrenheit), the Met Office tweeted.
The average temperature in February is between 6 and 8 degrees Celsius (42.8 and 46.4 degrees Fahrenheit), according to the Met Office.
