The weather changes from today, with the country entering a three-day bad weather due to the onset of the “cold lake” phenomenon.
According to Klearchos Marousakis, from today (24/5) the weather will start to change moving into the weekend, with showers and local thunderstorms expected to occur in northern Greece. However, unstable air masses will then start to hit more and more areas, due to the “cool pool” phenomenon.
According to the forecast of meteorologist Panagiotis Giannopoulos, storms and a drop in temperature are coming.
For the weekend, in the mainland “there will be localised showers and thunderstorms. Most phenomena will occur between the hours of noon – afternoon. “Spring instability we call this. It’s still unclear what will happen Sunday night.”
Maps showing the areas where there will be rain and thunderstorms from today until Sunday were posted on social media by meteorologist Sakis Arnaoutoglou.
The rains will start today in northern Greece, while on Saturday they will extend to central Greece and the Peloponnese, both in mountainous and lowland areas. On Sunday, the rains will be heavy in many areas of the mainland of the country, while Attica, the Cyclades, the Ionian Islands and Crete are expected to be affected.
What is the “Cold Pool” phenomenon?
For the same term there is a second name as “Cold drop” or “Cold Drop”. But what exactly is this natural phenomenon and what is the difference between it and “Cold Pools or Pools” near the ground?
A “Cold Lake” in meteorology is a cold region of the atmosphere surrounded by warm air masses. The vertical extent of these cold gas masses occupies almost all of the Troposphere and the movement of the air is cyclical (counterclockwise).
The existence of cold gas masses above warm and moist air masses near the ground leads to the creation of “instability”, i.e. a large drop in temperature over height.
Instability is a necessary condition for the formation of storms, the other two conditions being the existence of moist gas masses and a cause of lifting of the gas masses. If even one of these three elements is missing, then the formation of storms is impossible.
The weather today:
generally clear weather is expected but in the afternoon and afternoon in the mountainous continental areas and in lower altitude areas of the northern continent, local clouds will develop. Local rainfall and sporadic thunderstorms will occur in the afternoon and afternoon in Central and Eastern Macedonia and Thrace.

Winds in the Central and North Aegean will blow from the north from 2 to 4 Beaufort. In the southwestern Aegean, winds will initially blow from westerly directions from 3 to 5 Beaufort but from the morning they will become variable from 2 to 4 Beaufort. In the Dodecanese, winds will blow from the northwest 3 to 5 Beaufort and in the afternoon and afternoon 4 to 6 Beaufort. In the Ionian Sea the winds will blow from the north at 2 to 4 Beaufort.

The temperature will drop slightly mainly in the west, central and northern regions. In the Ionian, western, central and northern continental areas it will reach 24 to 26 and locally 27 degrees Celsius, in the rest of the country 24 to 28 and locally in the south 29 degrees Celsius.
FORECAST FOR SUNDAY 26-05-2024
In Thrace and the eastern Aegean thin clouds, sometimes more dense. In the rest of the country increasing clouds with local rain mainly in the mainland. Sporadic thunderstorms will occur from the early morning hours in the west-northwest, the central continent and gradually in the Peloponnese. The phenomena will stop in the evening in most areas.
Winds will blow from the north 3 to 5, in the Aegean 6 and locally in the north 7 Beaufort.
