This past week was an interesting one for many people who know they must follow the local weather.  I spoke to people in the Northwest, Midwest, the NorthEast, and near our nation’s capitol, and the recurring theme was an unpredictability in the reporting of what the weather was going to be like this weekend.  Massively shifting numbers of no snow, to big snow, to somewhere near nothing, or cataclysmic.  It got to the point that the New York Times decided to call out Apple Weather as being the culprit, but the reports were chaotic in multiple apps, and chaotic compared to others.  I tinkered a little bit with Weather Underground, Apple Maps, and Accuweather, on a few locations.  Frankly, none of them ever agreed with themselves from 6-8 hours prior, let alone each other.  The reality behind the scenes, is that weather is series of educated and calculated guesses, and sometimes everyone guesses the same, and sometimes they don’t.  It’s also subject to change based upon conditions that aren’t readily obvious, which means it may not be accurate.
