Heat in the middle of winter: weather forecast

A rare weather event is coming: +26°C before Christmas! A similar phenomenon, according to meteorologists, was recorded in Greece only three times since 1963.

A rare climate event, which will be characterized as “very high temperatures for the season”, will come before Christmas. As meteorologist Kostas Lagouvardos, director of research at meteo.gr at the Athens Observatory, explains to iefimerida.gr, after a temporary drop in temperature, from Wednesday to next Monday, December 19, there will be a “period of high temperatures”.

A warm weather front will hit the eastern Mediterranean, engulfing southern Italy and the Balkans.

To track the air temperature indicator, meteorologists outside the Earth rely on the values ​​of t at an altitude of 1500 meters. “On Thursday, Friday and Saturday, when we expect the peak of the warm weather front, at an altitude of 1500 meters the temperature deviation reaches 10 and 12 degrees,” says Costas Lagouvardos. According to the forecaster, “in the last decade in the second half of December, the average temperature in Athens was +15°C, in Crete +16.5°C, and in Thessaloniki +11°C.” In the coming days, he adds, “We are expecting +25 to 26°C in Crete, which is 10 degrees below the normal temperature on Earth. According to our estimates, in Athens the temperature will be 5-6 degrees above the norm, and in Thessaloniki – 6-7 degrees.”

Kostas Laguvardos notes: “At the same time, we do not expect rain during this period, except today and tomorrow on December 12-13, and the southerly winds of the previous days will subside. Looking at the available evidence from previous decades, Costas Laguvardos concludes that looming heat wave will be a significant event.

“The previous corresponding warm invasion for the same period was in the first decade of December 2010. Then we had +23°C in Athens and +29°C in Chania. The second important similar event took place between December 20 and 23, 1963, when the temperature in Athens again reached +23°C. The third was recorded in 1996. Then, from December 22 to 24, we observed +21°C in Athens and +28°C in Chania. We will have to see how this year’s warm invasion goes and whether it beats the record of 2010, which was also the most serious event in meteorology,” summed up Kostas Lagouvardos, forecaster at the National Observatory of Athens.
