To their credit, the weather people are decent at figuring out the general temperature. "It will be hot" or "it will be cool" are pretty much the most they can handle, as everything else changes hourly. They'll be a zero percentage chance of rain for the day called at 8am, only to change to 70% chance of evening rain by 3pm. I get that weather is a complex, unpredictable system...but if things are going to switch that rapidly, what's the point of even guessing...and what's the point of saying 0%?
Today is another example as my phone is currently telling me it's 75 degrees outside yet, as a human who's experienced 75 degree weather before, I know that it's much warmer outside. When your phone isn't as accurate as a physical thermometer, I think it's time to give it up. Of course I can't give up the weather app...mainly because it's impossible to uninstall from the operating system, so I'll be forced to say hello to it on the home screen as I flip through the apps everyday. Maybe though, I'll learn to stop trusting everything it says. If I want the current weather, the best option might just be to go outside...and see if it's raining.
