The weather apps in our phones not only have changed the ways we check the weather, they also are a source of amusement—and amazement.
In the olden, pre-app days, you’d check the weather by looking out the window, or maybe watching the local news for tomorrow’s forecast. But the weather apps give you seven days of weather at a glance, with icons and scientific-seeming percentages about the chance of rain. And when you live in Columbus, or Stonington, or anywhere but Arizona, there’s always rain somewhere in the forecast.
The entertainment value comes from wondering how they develop those awesomely precise percentages, and then watching them change repeatedly. What distinguishes a 30 percent chance of rain five days from now from a 40, or 50, or 60 percent chance? What factors do the apps consider in assigning those values? And the frequency of change makes you wonder why you pay attention to the long-term forecasts in the first place. In the few hours since the screen shot above was taken, Thursday has gone from 50 percent chance of rain to the unblocked total sun icon. What titanic movement of massive weather fronts caused that abrupt change?
The weather apps, like some of our politicians, are frequently wrong—but never in doubt.
