Temperatures will gradually rise through the end of the week. According to the latest forecast data from meteo.gr / National Observatory of Athens, during the next few days the atmospheric circulation will favor the transfer of warm air masses towards our country. In fact, from tomorrow (25/09) onwards the air masses affecting the weather in Greece are expected to be warmer than normal for the season.

The graph in the following picture shows the range of variation of the temperature forecast until 29/09 at an altitude of about 1500 meters above Athens. The red line shows the “warmest” scenario while the blue line shows the “coldest” scenario. The green line shows the variation of the mean temperature based on all available scenarios of the model. Finally, the black horizontal line marks the approximate mean value for the period according to data for the period 1991-2020. As can be seen, all scenarios confirm the gradual increase in temperature and the higher than normal values for the season. The altitude of 1500 m is used to study temperature changes in the lower part of the atmosphere. It is noted that the final temperature configuration near the ground depends on a number of factors such as e.g. the presence/absence of clouds and phenomena and wind.

Marousakis’ forecast for the development of the phenomena

“In the temperature diagram or as I like to call it “truth diagram” since it includes the multiple solutions of the meteorological models that show us the prevailing trend of the weather, we can observe the upward trajectory of the temperature where towards the end of the week in the prefecture of Attica we will find mercury near 34 degrees Celsius as the maximum temperature.

It is also worth noting that observing the same diagram towards its end we see the temperature curves descending steeply which shows us a sharp change in the weather that will be accompanied by a vertical drop in mercury and which is timed for the beginning of next week and which we will refer to when our forecast data can lead to more stable conclusions.

The temperatures in the country in the first few days of October

Until then, enjoy the summer with a caution until Wednesday to the west where instability seems to prevail.”

A strong blocking anticyclone is coming in early October – What problems it creates for the weather

A strong blocking anticyclone is expected to develop in the coming period, resulting in the absence of rainfall, says Thodoros Kolydas in a new post.

The anticyclone blocker, it says, will block and prevent central European systems from moving into our region.

The post by Thodoros Kolydas

THE WEATHER FORECAST UP TO THE FIRST WEEK OF OCTOBER

✅The rise in temperature from the beginning of next week will be the main feature of the weather. From early October we return to normal temperature levels.

✅In terms of precipitation, nothing encouraging is discernible. The only exception is some phenomena at the end of the month. Since the beginning of October a strong blocking anticyclone has been developing. This strong anticyclone will block and prevent the central European systems from moving towards our region and this will result in the absence of rain.
