Purpose of thread is to provide an easily obtained resource to historical snowfall data.  In particular, this thread will focus on climatilogical data for various official observational sites throughout the Mid-atlantic region of the U.S.  This will be an ongoing endeavor that I'll continuously update, as time permits.              

That aside, please feel free to share any relevant data or observations, here, as well.
