If I were writing a heartwarming, Hallmark-esque family movie, I might include a scene where a little girl who used to wish for snow days returns to her hometown as a single mother, watching her young son participate in the same ritual.

That scene came to life on Tuesday when an unexpected holiday snowfall canceled school in Baltimore and many other districts.
