The app on my phone, it tells me it's sunny, 20 degrees. Meanwhile there's a gale force wind whipping up the lake, mangling the pagodas, tearing up the umbrellas.
Check the app on your phone again. Oh, now it's updating, rain.
Every day, the forecast dictating where I'll be working, the forecast off - invariably - by an average of 10 degrees above or below the target.
You want to know the weather? Look at your phone - then take your best guess. Whatever it is it won't be that.
