Mid-January and only 0.6 inches of snow. Bob Brown in Cockeysville wonders: "When was the last time there was no snow through the middle of January? Is there a year when no snow was recorded?" Only a trace had fallen at BWI by Feb. 1, 1973. That season saw just 1.2 inches. It also happened in 1913-1914, but 23 inches fell after Feb. 1. Skimpiest snow season? Seven-tenths of an inch, in 1949-1950.
