Don’t be surprised if you see a few snowflakes falling later tonight. And then again, don’t be surprised if you don’t see anything either. A fast-moving but moisture-starved storm system will slip through the region tonight and may result in some “conversational snow” flurries. Even so, temperatures will be above freezing, so no accumulation is expected. By Sunday, thoughts of snow will be well in the rearview mirror as temperatures rise back into the mid-50s.

       Storm Arwen packs a punch: Storm Arwen developed over the North Sea late Thursday and lashed Britain with hurricane-force winds, massive waves and some early-season snow. The storm’s intensity resulted in a rare red warning for wind being issued by the Met Office for eastern Scotland and northeast England and unfortunately resulted in at least three deaths so far. In those areas, several hurricane-force wind gusts were recorded, and wave heights in the North Sea reached levels not seen in nearly a century.

       The unusual position and track of the storm dragged in a lot of cold air from Scandinavia, where they are currently experiencing some record-cold temperatures. That air was cold enough to change precipitation to snow for lots of locations in England on Saturday morning, giving many people a nice early taste of winter.
