Washington D.C, Baltimore, Maryland and St. Louis, Missouri all saw their biggest snowstorms in several years this weekend. St. Louis picked up 10.9" of snow between Friday and Saturday, snarling traffic and basically bringing the city to a standstill on Friday night and Saturday, but that snow total also made it St. Louis's biggest snow event since late March of 2013, a nearly six-year stretch. For reference, St. Louis averages about 18.8" of snow in a full season, so this snowstorm alone accounts for more than half of St. Louis's average annual snow. Meanwhile, Washington, D.C. and nearby Baltimore saw their biggest snows since the epic January 2016 blizzard that dumped over 20" of snow in both cities. Washington and Baltimore both officially had almost six inches as of Sunday afternoon, making it both cities' biggest snows in three years. Washington averages just over 15" of snow in a full winter, so this storm will likely end up accounting for about half of that figure alone, once the final numbers are tabulated early Monday.
