Weather: How the polar jet stream will evolve – 2024-04-18 04:30:34

The weather will drive us crazy as from the African dust, there will be a drop in temperature, then it will rise again and then the dust will return again, reminiscent of a “cardiogram”. And all this until the beginning of next week.

According to Meteo, rains and storms are expected from today, mainly in the north and north-west continents, in the east of Thessaly, in South Crete and in the mountains of the rest of the continents. During the night to Thursday 18/04, the effects will mainly affect Thrace, the eastern parts of the Aegean and the mountains of the western and southern continents, while showing weakening.

According to the categorization of rainfall episodes (Regional Precipitation Index), which is applied by the Meteo unit of the National Observatory of Athens, the rainfall episode for Wednesday 04/17 is classified as Category 2 (Moderate).

The southerly winds in the Aegean will reach 6-7 Beaufort in places. From the first evening hours they will gradually turn to westerlies of the same intensity. In the Ionian, westerly winds are not expected to exceed 5-6 Beaufort.

The temperature will drop and will not exceed 24-26 °C in continental areas and 20-23 °C in island areas.

Finally, the concentrations of dust in the atmosphere will be increased and there will be mud showers in places.

In detail, the forecast of meteorologists

Giorgos Tsatraphyllias: A polar air current is coming

A “polar air current” reaching Greece is expected to displace dust and bring a temperature drop of 10 degrees, according to Alpha’s meteorologist.

In fact, the two days from Friday to Saturday will bring snow in the mountains and several rains.

Giorgos Tsatraphyllia’s post in detail

“Polar jet displaces dust and drops temperature by 10 degrees! It also brings snow to the mountains and heavy rains on the two-day period Friday-Saturday.

Today is the last day with dust, with the mud rains keeping us busy until the evening mainly in the western and northern country. Thursday 18/4 is a transitional day. There will be localized showers in the west, north and east of the island country and the temperature will drop by 4 to 5 degrees.

However, on Friday and Saturday the “atmospheric river” (whirlwind) – picture – located high in the atmosphere will descend to more southern latitudes and will change the weather in the country with rain, storms, further drop in temperature and even snow! Specifically:

On Friday 19/4, large amounts of rain are expected in western and northern Greece, some snow at high altitudes (1400 m) and a drop in temperature.

On Saturday 20/4 the most rain (locally heavy) will occur in the morning hours in Thessaly, the Sporades, Macedonia, Thrace, the eastern Aegean and the Dodecanese. Strong north winds will also blow.

On Sunday 21/4 a second disturbance will create milder effects in central and northern Greece.”

Thodoris Kolidas: The scene changes after a while

The director of the EMY says that the temperature will drop significantly, but this will last until early next week, when it will start to rise again.
