A temporary improvement in the weather with rising temperatures over the weekend is expected, followed by a new significant change from the beginning of next week, bringing widespread and locally heavy rainfall, according to meteorologist Thodoris Kolydas.

In a post, the former director of the Hellenic National Meteorological Service (HNMS) noted that today only limited weather phenomena will occur, mainly in the southern parts of Greece, and these will gradually weaken.

Over the weekend, weather conditions will improve noticeably, with higher temperatures in most areas and generally mild conditions.

However, from early next week, another change in the weather is expected, with increased rainfall mainly in western and northern regions as well as the eastern Aegean, which may be locally heavy.
