Met Office meteorologist Marco Petagna has predicted that parts of north east Wales could see temperatures rise to 16C by the weekend. If that proves to be correct, it will be warmer here than in the Greek capital, which is forecast to have temperatures of around 10C on Saturday and 8C on Sunday. In a post on Twitter, Mr Petagna said: "Could see 16C this weekend NE Wales and E/NE Scotland!!! "Extremely mild S/SW winds and the foehn effect." The Foehn Effect is a a dry and warm down-slope wind that occurs to one side of mountains or hills.

North Wales could be warmer than Athens as Met Office predicts unseasonably high temperatures

(Image: wxcharts.com) The Met Office says that the Foehn Effect is "a change from wet and cold conditions one side of a mountain, to warmer and drier conditions on the other (leeward) side." The cause of the effect is complex, caused by condensation, turbulent mixing of different air currents and warming by the sun. Current forecasts on the Met office website indicate temperatures are more likely to be somewhere between 10C and 12C, although Mr Petagna has said the weather phenomenon could cause the mercury to rise even higher. It would take a big rise for the current December temperature record for Wales to be broken this weekend. That currently stands at 18C and was recorded in Abergwyngregyn on December 18, 1972. According to the Met Office, many of us will see double-digit temperatures from Friday through to Monday. A spokesman said: "Early rain will slowly clear through the morning [on Friday] leaving a dry afternoon, though staying on the windy side. "It will remain rather cloudy and feel very mild. "Dry Saturday and Sunday with some good spells of sunshine, but remaining breezy." After this period of milder conditions, the Met Office has stated that the weather will become more unsettled as we approach the new year. They said: "Towards the middle of next week, it looks to remain rather unsettled for a time as bands of wet and windy weather cross the UK. "Gales are possible at times, especially across northern and western parts. "Somewhat drier and colder conditions seem likely thereafter and look to continue into the first week of January. "During this more settled period, overnight frost is possible."
