This June seems to be weird with dry and warm weather in north and cool-rainy in south Europe. This is gonna change in the next days, but for how long?

 

You may follow us on facebook, instagram and youtube to stay weather-tuned!

 

According to the latest weather data, the atmospheric depressions in the ten-day period will follow a northern track. This will allow cooler, rainier and windier conditions in the north, while a fair weather system will shield south Europe for a while with dry and sunny weather.

In particular, Europe will be divided into two areas, a northern with unsettled or almost autumnal weather and a southern with dry and sunny weather around the average of the season. The regions from the north of Spain, France, north of Italy, north of Balkans and further to the north will be affected by coll, windy and rainy weather at times. Interestingly, there is even a possibility for some occasional snowfalls over Scandinavian mounts. Regions around north Spain, south France, north Italy, Switzerland and north-northwest Balkans will be mostly affected by afternoon/evening thunderstorms, which may be severe at places.

In south Europe, unsettled weather will make a break with warmer and drier conditions (around average). There is just a possibility for showers over the mounts of the northern areas of this region. Small possibility also occurs for a heat wave in south Iberia, south Italy and Cyprus.

 

This situation will be preserved till 4-6/2020, when unsettled weather will be back in south-southeast, while warm air masses may prefere again a northern track!

 

 

 

Obviously spring is a season of unsettled weather with ups and downs. However, this spring seems to follow almost strictly wintry or summer patterns.

 

In the satellite image you may observe snow covered Scandinavia and African dust over southeast Europe.

 

You may see the current observations in Thessaloniki HERE.

During the last week, extreme weather was observed across Europe forming a weather dipole between north and south countries. Snowfalls occurred in Scandinavia and Russia, while an unusual heat wave for the season took place in Greece.

In particular, the temperature in northern Europe was observed to be in general higher than the average for May by 8-10°C (without breaking any record). However, negative temperatures were observed in many places (e.g. in Stockholm the temperature dropped to -2°C ον 14/5/2020). In the following chart you may see temperature deviations from the temperature average of this season on 16/5/2020. It should be highlighted that the entire week (11-17/5/2020) the situation was more or less in the same pattern.

 

 

In contrast, in the southeast corner of Europe, we observed the highest temperatures ever for the month of May. In Athens and Thessaloniki (two biggest cities in Greece) the temperatures reached the extreme highest values for this month (36°C and 33°C respectively). The highest ever temperature for May was recoerded in southern Greece, in Sparta, where the weather station recorded a highest value of slightly above than 40°C.

The following videos showing this weather contrast over Europe. The first three videos come from Russia and Norway:

 

In contrast, Greeks searched for a cool place by the sea close by the large urban regions. The first video is from Epanomi (Thessaloniki) and the second from Vouliagmeni (Athens):

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:

A new snow depth record was recorded last week in Iran. The news is confirmed by both videos and (indirectly) meteorological synoptic maps.

 

This winter has been quite selective “offering” snow to very specific regions in the northern hemisphere. Once again, Iran was hit by a snow system last Monday-Tuesday (10-11/2/2020). Reports say that higher ground regions may have more than 4 meters of snow. It should be highlighted that many mountains exceed 2000 meters of altitude. A new record has now been achieved in Khalkhal of northwest Iran (altitude of 1800 meters). However, this time snow reached even over low ground rregions, such as Rasht at 0 meters of altitude.

 

Some synoptic chats show quite extreme conditions in the region last Monday over the south coastline of Caspian Sea

 

In the next video you may see some nice snow in the city of Rasht in northern Iran at altitude of 0 meters:

 

While, in Khalkhal at 1800 meters, the snow exceeded 4 meters:

Roads and railways have closed, trains have been canceled and schools have closed across Romania after the recent snowfall and blizzard.

The A2 highway, linking Bucharest to Constanța, a city on the Romanian Black Sea coast, closed on the evening of February 5 because of the blizzard, G4media.ro reported.

In Buzău, Brăila, Ialomița and Tulcea counties, all national and county roads were closed between 22:00 and 08:00 for all vehicles, except the intervention ones.

Because of the weather conditions, the state-owned railway operator CFR Călători canceled over 30 train rides. The canceled rides are listed here.

In Bucharest, the blizzard caused more than 100 trees to fall down over roads and cars, while 4 billboards and 29 construction elements also fell down, the Bucharest-Ilfov Emergency Inspectorate announced.

Two traffic lights poles fell down and a total of 19 interventions took place in Ilfov county, in places where trees or poles had fallen down.

The public transport in Bucharest was disrupted on the morning of February 6, when the circulation of trams was blocked. The tram line 41 was blocked after a bus skidded over the tram line in the Presei Libere Square.

No trams were leaving from the square, while in the opposite direction trams were blocked in the Agronomie area. The trams running on lines 1, 8, 11, 25 and 47 were also blocked on Progresului Road, the Bucharest Public Transport Company (STB) announced.

Across the country, schools in four counties are closed on February 6 because of the weather. The Education Ministry announced that no classes will be held in schools in Brăila, Buzău, Călărași and Ialomița counties, where blizzard and strong winds are expected.

As such, a total of 102 schools remain closed in Brăila, 155 in Buzău, 97 in Călărași, and 93 in Ialomița. Schools will also be closed in Tulcea county, except for those in the town of Tulcea.

There are remarkable signs showing that the weather will change within February spreading arctic cold and snow in Europe. The cause is the already predicted breaking of the polar vortex during the current week. We should make clear that when we say “polar vortex” we refer to a solid cold air mass with a structure along the profile of the troposphere reaching the stratosphere, which is located geographically within the arctic circle. One of the reasons that this vortex is developed during the winter is the lack (or the limited) sunlight.

When this air mas breaks being intruded by anticyclonic systems, then the equilibrium in the circulation of the north hemisphere is perturbed and a part of this cold air mass moves southwards.

This time, there are reliable signs that the weather will change significantly in Europe this last month of the winter. In early February, we should expect one severe cold outbreak in northeast America, which should come with severe cold and snow there. However, this will be just the beginning as it will affect through a domino effect the weather of Europe perturbing the equilibrium between cold and warm air masses in north hemisphere (figure 1).

For now, it is a bit of unknown how exactly this arctic mass will move over Europe. The most of scenarios keen on moving the cold to the central/east of Europe. However, there are a few possibilities that this arctic mass will move westwards.

In any case, every meteorologist that respect himself and his scientific identity should highlight the fact that all this syllogism is based in possibilities and it is not a forecast yet.

The death toll has risen to 11 as the extreme weather conditions cause severe damage to the Ebro Delta in Catalonia, and coastal homes in Valencia

A powerful storm that was still affecting Catalonia on Thursday after sweeping across northern and eastern Spain for four days has claimed a new victim.

A man was found dead on Thursday in Jorba (Barcelona) after his car was dragged away by torrential rains, bringing the death toll from Storm Gloria to 11.

A person has also been reported missing in Cabacés (Tarragona), where he was last seen driving his car.

A total of five people remain unaccounted for since Gloria started battering the region with heavy rain and snow, winds of over 100 kilometers per hour and record-high waves.

Numerous municipalities in Catalonia continued to experience travel disruption on Thursday, and 130,000 students stayed home from school. In the city of Girona, authorities said that the Ter River has burst its banks in the neighborhoods of Pedret and Pont Major, while the waters of the Onyar continue to rise.

The towns of Deltebre and Alcanar, in Tarragona province, have asked to be declared disaster zones.

Early estimates place storm damage in Deltebre, where 25 meters of coastline have been swallowed up and 3,000 hectares of rice fields ruined, in the range of €9.5 million.

Spain’s prime minister, Pedro Sánchez of the Socialist Party (PSOE), visited some of the most-affected areas on Thursday.

Catalonia, the Valencia region and the Balearic Islands have borne the brunt of the storm.

Ebro Delta

The Ebro River Delta region in Catalonia has been severely affected by the storm, which pushed waves as far as three kilometers inland, ruining crops and altering fishing activities in the area.

The damage is particularly visible in coastal towns between L’Ampolla and Deltebre, on the left bank of the Ebro.

The sea has covered thousands of hectares of rice fields, where the salty water will damage soil fertility.

“This means ruin,” said Josep Colomines, captain of a fishing vessel from L’Ampolla.

A dozen red tuna fish lay mangled on the badly damaged seafront promenade, their heads still intact. Knives in hand, several people were busy cutting out the edible parts.

The animals probably ended up there from a nearby fish farm run by a company named Balfegó, which specializes in catching and fattening up tuna in cages near the coast.

“For now we haven’t been able to assess the damage, because the sea is still too rough,” said a company spokesperson.

Every beach in the Barcelona Metropolitan Area (AMB), from Castelldefels to Montgat, has sustained the worst damage seen in the last 30 years.

According to the AMB’s head of beaches, Dani Palacios, the damage to beach equipment alone is expected to be in excess of €250,000, and that is without counting the destruction of boardwalks and promenades, or the new sand that will have to be brought in to restore the areas to their former state.

Valencia

In the Valencia region, the storm has swallowed up entire beaches and dragged sand, seaweed, cane, driftwood, oil drums and even buoys hundreds of meters inland.

In Oliva, where authorities allowed residents to keep homes that were built too close to the coastline, one homeowner begged reporters not to publish photographs of the state of his property “or else they’ll take away even more land from us.”

“I’ve never seen anything like this. Maybe in 1982,” said a woman named Teresa inside one of the few cafeterias still open in the area.

In Jávea, the ground-floor premises of the buildings located along its small port promenade have been ravaged despite efforts to stop the waves with metal sheets and wooden planks.

“Never before has there been so much damage, with such strong waves,” said Diego, who works at La Bodeguita, a seafront restaurant in this popular tourist destination.

Starting before Christmas, the atmospheric circulation has changed over Europe with the coldest conditions being located over Balkans at the moment. Bu t what about next?

Analyzing the situation, we try to find clues in order to get an idea of the weather that we should expect for the next fortnight.

The first and very important hint is the expected position of the Azores anticyclone, which is the main system that manages and distributes the cold air over Europe. Having a look at figure 1 we can realize that most of western Europe is highly likely to be under anticyclonic conditions for a prolonged period and only the very north countries (e.g. Scandinavia) will be affected by some cyclonic systems. As a mater of fact, the predicted surface atmospheric pressure for the next fortnight is around 1020 to 1030mb, a forecast that is supported by most of GFS prognostic members, but also by most of ECMWF ones (see graphs for Iberia, Central France, South UK και Norway).

The only unclear point is how north the anticyclone will move. This can be seen in the ensembles of the UK and Norway. The position of the anticyclone is crucial if we want to make a prediction of the exact regions that will be affected by one or more consecutive cold outbreaks in eastern Europe. These cold outbreaks will reach fairly south countries as Balkans and even Greece till at least 13/1/2020.

Figure 1 – GFS ensemble forecast till 14/1/2020

 

 

In the meanwhile, NAO and AO indices seem to drop to slightly negative values highlighting the possibility for weakening any systems in north Atlantic ocean and the southern movement of cold air masses (figure 2).

Finally, in figure 3 a new stratospheric heating is expected in Siberia and eastern Europe, which means that the cold air masses that were established and developed there will released and move southwards to eastern Europe. This is definitely another clue we should take into account.

So, concluding for the first fifteen days of January we should expect a quite mild weather in most of western and central Europe. However, cold weather and snow may visit eastern Europe from Italy and to the east and from eastern Scandinavia to Greece.

North Iceland is affected by severe snowfalls today (10/12/2019) and till early Thursday. The scenery is almost spooky.

 

Impressive pictures coming from Iceland weather cameras, while a brave man goes out driving into the snow. At some places snow depth is expected to exceed 150 cm!

 

Here are some print-screens from the live weather cameras in northern Iceland:

Heavy snowfalls occurred in north Italy during the last days. The Italian Alps were buried in a snow layer of more than 1.5 meters at places.

Although October and November are the most humid months of the year for Italy, this year the precipitation heights reached record values.

Severe snowfalls started in the Italian Alps on 15th November covering surfaces with a 1.5 meters-thick layer of fresh snow.

 

The accomodation Madonna di Campiglio is buried in snow. A similar situation is presented in the lake Pragser Wildsee and the town Cuneo.

 

 

People shared loads of videos and pictures of the heavy snowfall in the region on tweeter:

Meanwhile, heavy rain occurred in Trento, where finally turned into snow. The snow depth reached 0.8-1.2 meters. According to the local authorities, there are disruptions in the local road network.

The phenomena will persist until Tuesday (19/11/2019).
