WSI: Mild Start to November Followed by Colder Weather Through December

Coldest Risk Early and Potentially Late this Winter with ‘January Thaw’

Andover, MA, 23 October 2013 — WSI (Weather Services International) expects below-normal temperatures for the upcoming period (November-January) across most of the northern mainland, eastern Europe, and western Russia, with above-normal temperatures elsewhere.

According to WSI Meteorologist Dr. Todd Crawford: “A very mild westerly flow pattern has become established across Europe, and it appears as if this pattern will persist into at least early November. However, our internal statistical analysis suggests an increasing threat of North Atlantic blocking and colder weather later in November and through December. By January, however, dynamical and statistical models suggest a quick transition to a much milder pattern across much of mainland Europe as westerly flow becomes re-established. Finally, the February-March pattern will be driven by the existence (or not) of a sudden stratospheric warming event, which would disrupt the polar vortex and result in sharply increased chances of colder temperatures as the winter ends.”

In November, WSI forecasts:
Nordic Region – Warmer than normal
UK – Warmer than normal
Northern Mainland – Warmer than normal west, colder than normal east
Southern Mainland – Warmer than normal, except far Southeast

In December, WSI forecasts:
Nordic Region – Colder than normal, except extreme northern sections
UK – Colder than normal
Northern Mainland – Colder than normal
Southern Mainland – Colder than normal, except southern half of Iberia and Italy

In January, WSI forecasts:
Nordic Region – Warmer than normal
UK – Warmer than normal
Northern Mainland – Warmer than normal, except extreme eastern sections
Southern Mainland – Warmer than normal, except extreme Southeast
