      In mid-November 2022, frigid air swept across Lake Erie and Lake   
      Ontario, triggering a long-duration lake effect snow event that dropped   
      record snowfall in parts of western New York. The first snowflakes fell   
      on November 16, with formation of high-intensity bands of snow   
      following soon after.   
      
      On November 19, the Buffalo Airport reported a record snowfall of 17.2   
      inches for that date—handily beating the previous record of 7.6 inches   
      which fell on the same date in 2014. By that time, Orchard Park, south   
      of Buffalo, was shivering under a monumental 77 inches of fresh snow.   
      The snow came with a price, snarling traffic and dropping visibility to   
      less than a half-mile at times. Media reported at least two deaths due   
      to the storm and more than 200 people requiring emergency service   
      response or rescue.   
      
      On November 21, as falling flakes began to disappear and the skies to   
      clear, the National Weather Service tabulated totals for the storm   
      while residents living in the heaviest bands continued to dig out. The   
      town of Hamburg, just south of Buffalo, won the prize for the deepest   
      snow, measuring-in at 81 inches. Nearby Orchard Park was next in line,   
      with a storm total of 80 inches. Meanwhile, Tonawanda, a northern   
      suburb of Buffalo, registered a relatively-sparse 12.1 inches. Such   
      wide differences in snow accumulation are common in lake-effect snow,   
      due to the formation of snow bands that can be relatively narrow.   
      
      The Moderate Resolution Imaging Spectroradiometer (MODIS) on board   
      NASA’s Terra satellite acquired a true-color image of the aftermath of   
      the snowstorm on November 21 as skies began to clear. Clouds remain   
      heavy in the west and over Lake Ontario while sediment swirls in Lake   
      Erie. Snow accumulation is heaviest in a ring around Lake Erie,   
      especially in the northeast.   
      
      Lake-effect snow occurs along the eastern edge of the Great Lakes when   
      icy wind blows across the lakes from Canada. The wind picks up   
      relatively warm, moist air over the lakes and pushes it over land,   
      where the air is cooler. When the moist air encounters cooler   
      temperatures over land, the water condenses into precipitation, which   
      in cold temperatures falls as snow.
