Got this tidbit in a work email:
Another round of high impact winter weather is slated to occur from Friday into Sunday. This event is likely to equal or exceed that of the December 19, 2009 storm and may resemble the March 18-22, 1958 storm in terms of duration and snowfall. In that event, areas of Baltimore County received 4 feet of snow.
Awesome! Now to stock up on stuff just in case. After that, I need to go down to the basement and locate the Sled!
