I personally don't use Microsoft's weather tool, and I recommend not to. The best option is to go to AccuWeather's website and in the location bar, type in your postal (ZIP) code. Then it will give you super accurate weather. I barely trust Microsoft with anything, which is why I love Windows 8.1 so much - it doesn't steal as much of your information as Windows 10 - I hate that operating system. Anyway, I recommend not updating your Windows because Microsoft just puts more and more junk into their operating systems. I bet Windows 11 is going to be a real mess.
Conclusion: Use AccuWeather, just type in your ZIP code and you're all set.
