The turn of the year will be even warmer than the Christmas period. Temperatures will rise to 15 °C thanks to a warm southwesterly flow. A slight cooling will occur during the first week of January, meteorologist Dagmar Honsová said.
On Thursday, cloudy to overcast skies will prevail with isolated showers. These will occur mainly in mountainous areas, and they will be mixed or snowy at higher altitudes. These should increase during the day from the west. Temperatures will reach 6 to 10 °C.
Friday will be mostly cloudy to overcast again, with showers in some places. Night-time temperatures will drop to 6 to 2 °C, with daytime temperatures rising to 6 to 10 °C.
“On Saturday, New Year’s Eve, it will be cloudy to overcast, with rain or showers at the beginning of the day, especially in mountainous areas. During the afternoon, the precipitation will stop, and the clouds will break through to become partly cloudy in places,” Honsová said, adding that Saturday morning will be warm, with temperatures dropping to 9 to 4 °C in Bohemia, but 1 °C in the east. During the day, it will stop at between 11 and 15 °C, but in the Polabie region, it will be up to 16 °C. It will be cooler in the east, where afternoon highs will reach around 10 °C.
The start of the new year will offer partly cloudy skies on Sunday, with fog and low clouds in the east in the morning. Temperatures will drop to between 10 and 4 °C at night and reach 11 to 15 °C during the day, with around 10 °C in the east.
Last year was also abnormally warm at the turn of the year, and numerous records were broken, including the one in Klementinum. On New Year’s Day, the temperature there rose to 14.2 °C. The extreme cooling of 1978–1979 will not be repeated this time.
