November to January outlook from WSI
"For the upcoming November–January period, The Weather Company, an IBM Business, is forecasting slightly above normal temperatures across the United Kingdom and Western Europe, with more substantial positive temperature anomalies expected across eastern Europe.
“The colder weather in October, driven by a strong Scandinavian blocking ridge, is not necessarily a sign of things to come this winter,” said Dr. Todd Crawford, chief meteorologist, The Weather Company. “We are monitoring this blocking pattern, and if it remains through November, it could indicate a weakened polar vortex that persists through winter, resulting in an increased risk of colder weather for Europe. For now, we are hesitant to embrace the idea of an unusually cold winter, but we do expect abundant intra-seasonal variability that will provide more spells of cold weather than we’ve seen in the last three winters across western Europe. All evidence suggests another unusually mild winter across eastern Europe.”
