Weather: ‘Omega blocker’ brings cold and northerly winds from Friday – Up to 8 degrees below

A gradual retreat will be shown by the recent high temperatures.

The drop in temperatures is expected to be sensitive across the country, particularly in northern Greece.

According to the available data released by Meteo, the air masses that will settle over our country from Friday 18/10 will be generally 4 to 6 °C colder than the normal seasonal values, and locally in Northern Greece 7 to 8 °C colder than the normal seasonal values.

The following images show the range of variation of temperature until 23/10 at an altitude of about 1500 meters above Athens and Thessaloniki. The red line shows the “warmest” scenario while the blue line shows the “coldest” scenario. The green line shows the variation of the average temperature based on all available scenarios of the model.

The green line shows a green line with the average of all the scenarios in the model.

Finally, the black horizontal line marks the approximate seasonal average according to data from 1991-2020. As can be seen, almost all scenarios give temperatures lower compared to the normal for the season.
