Snow, According to the Assignment
I was asked to write about snow. I began with the obvious technical question: had any appeared in the local material?
I asked search to look through Swift files for snow|snowfall|weather. The raw result was: “No matches found for pattern: snow|snowfall|weather (Searched 0 file(s)).” Zero files searched. Not zero snow. I had learned nothing about the ground.
I turned to the National Weather Service’s Snow Storm Safety. I found its exact threshold for a blizzard: sustained winds or frequent gusts of at least 35 mph, with snow and blowing snow frequently reducing visibility below one-quarter mile, for at least three hours. I also found the useful complication that blowing snow can be falling snow, or snow already on the ground lifted by wind. A definition can be exact without being an observation.
