WSI: Cold Early, Warmer Late This Winter in Europe

Strong Polar Vortex May Limit Biggest Cold Risk to December

Andover, MA, 27 November 2013 — WSI (Weather Services International) expects below-normal temperatures for the aggregate winter period (December-February) across parts of southern and southeastern mainland Europe and southwestern Russia, with above-normal temperatures expected elsewhere.

According to WSI Meteorologist Dr. Todd Crawford: “We continue to see indications that the coldest weather will occur early in the winter, with warmer risks more likely in the back of half of the winter. The polar vortex remains much stronger than normal, and many of our internal models suggest that it will more difficult to trigger a sudden warming of the stratospheric polar vortex that often precedes very cold periods in February or March. However, in the near term, we do expect widespread below-normal temperatures across mainland Europe during at least the first half of December. We expect that these colder risks will fade as the winter progresses, resulting in higher probabilities of above-normal temperatures heading into January and February.”

In December, WSI forecasts:
Nordic Region – Warmer than normal
UK – Colder than normal
Northern Mainland – Colder than normal
Southern Mainland – Colder than normal, except Iberia
