WSI Forecasts a Cold Winter in Northern Mainland, parts of UK, Scandinavia
WSI expects the upcoming period (December-February) to average cooler than normal in Scandinavia, parts of the UK, and the northern mainland. “The combination of the current El Nino event, abundant Eurasian snow cover, and a favourable pattern of ocean temperatures in the Atlantic Ocean suggest that this winter will be a cold one across much of northern and central Europe, especially after the New Year” said WSI seasonal forecaster Dr. Todd Crawford. “For the UK, we expect total winter energy usage to be somewhere between that of the last two winters.”
