Noord- en Noordwest-Europa zou te maken krijgen met een droge winter. De straalstroom met stormdepressies zou een zuidelijke koers nemen richting Zuid-Frankrijk en het Middellandse Zeegebied. Volgens AccuWeather zou vooral in de tweede helft van de winter het risico op uitbraken van koude lucht toenemen, met in januari en februari regelmatig oostenwinden.
Al met al komt dat redelijk overeen met de winterverwachting van Weer.nl, geschreven door Reinout van den Born vorige week. Ook volgens die verwachting zou het wel eens een koude en droge winter kunnen worden. Ook volgens de Duitse meteoroloog Kai Zorn zou er een verhoogde kans op noordelijke hogedrukgebieden zijn, met kans op zogenaamde Grenzwetterlagen (GWL). Ook daar valt wel iets voor te zeggen volgens de verwachting van AccuWeather.
Hier een stukje van de tekst:
Unlike its stormy counterpart to the south, Northern Europe is not predicted to face unsettled weather this winter.
Windstorms are not expected to frequently sweep from west to east this season, which spells fewer impacts for portions of the United Kingdom, Ireland, Germany, Denmark, Norway and Sweden, Roys explained.
Due in part to a lack of frequent windstorms, prolonged stretches of drier weather are in store for eastern France, Germany, Sweden and Norway.
In addition, temperatures are not anticipated to be prone to any extreme variations for the first half of the winter. This could spell relief for residents across Northern Europe concerned about heating costs this winter.
However, Old Man Winter won’t be content with staying in the shadows for the entire duration of the season. Later this winter, the opportunity for prolonged bouts of cold air will arrive across Northern Europe, especially across Ireland and the United Kingdom.
As the second half of the season approaches, the predominant wind direction will shift across northwestern Europe and become more easterly in nature. Since the core of cold air across the European continent is forecast to set up over the east, an easterly wind will be able to transport that chilly air farther to the west.
Temperatures during the second half of winter will dip to near-normal and below-normal levels over northwestern Europe, according to Roys.
On top of chilly winds out of the east, the La Niña phase will increase the opportunity for snow across the United Kingdom and Ireland as well as areas from France to Poland, especially later in the season.
“Snow is not necessarily going to come from any individual big storm, but there will be frequent batches of light to moderate snow that can produce a bit of accumulation,” Roys said.
