But from the user perspective there is huge difference between +1C tomorrow and -3C. Really? I'd read those both as "near freezing, going to need a decent coat".

In Italy forecast are so unreliable they cannot predict rain in the evening from the morning. I don't know if it's because current climate change is throwing off models but short term forecast accuracy is terrible and I'm recently acutely aware of that since I switched to public transport for my commute.

#26> In 2009, a back-of-the-envelope study estimated that U.S. adults check the weather forecast about 300 billion times per year. That's every single adult in the United States checking the weather four times a day . A bit more than I would have expected…
This number probably includes things like swiping to the leftmost home screen on your phone to see the weather widget at the top. When it's that easy you can often check the weather unintentionally.

The windy.com site is really useful. It is the only way I know to get the ECMWF forecasts for free. As far as I know all the AccuWeather and similar spyware apps use the freely available but inferior GFS model.

+1 means that the packed snow is going to melt on top and then probably re-freeze, making everything super slippery. So I need to remove as much snow from the paths as possible and spread sand, and remind the kids to be careful. -3 means relax.
