Meant to share this earlier in a discussion about weather apps, but forgot. This site is interesting because it scores different weather apps based on their previous accuracy in your area. Most of the best ones, unfortunately, at least in my experience, are probably going to be proprietary. I would always grumble to Mrs. Hedge that the weather apps were always wrong, and it turned out that the one I was using had something like a 50% success rate for my area! So no wonder.
Is there something similar for Europe?
I generally dont trust 5 or 7 day forcasts. I really personally think that for most people nothing more than a 3 day forcast is needed until we get faster computers and the margin of error is reduced more. Set most weather apps to 3 day forcasts by default with an option to expand to 7 with a big warning that accuracy drops off significantly past day 3
weather.gov for anyone in the US?
Look for the app NWS Now, just puts the info from https://NOAA.gov into “app form” with alerts and notices for changes if you want. Supports multiple locations.
