This also surprises me. The weather app on my iphone has been atrocious with local same-day forecasts lately. It will say that the forecast for noon is sunny when it is 11:50 and dumping rain. It sometimes gets the overall idea that warmer or colder weather is coming sometime soon but it’s off by up to 2 days. I haven’t bothered to look for better sources, but it might be worth doing some research and comparison.
as mentioned elsewhere, weather.gov has accurate enough predictions for stuff like rain.
It's good enough that i can confidently claim on a wednesday that i need to leave some place before 16:30 because there's a storm coming that i saw on weather.gov the preceeding sunday or monday. and there's a 75% chance that it will be raining at 16:30. This may not sound impressive, but in Louisiana knowing when a storm system is coming as opposed to some rain is probably pretty taxing on weather models; and is nearly universally good information to have.
I find i can't rely on the temperature and humidity readings, the "local prediction center" is in a concrete jungle (near an "international" airport, to boot), and "town" is consistently 7 degrees warmer than where i reside. Other than that, if it says temp below 32, it will freeze. if there's a heat advisory, we feel it too, just less so than town 20 miles away.
Hope this helps, and i hope other countries/regions do this as well as weather.gov - it just works! I do use ventusky for tropical system paths and the like, if the gov site allcaps weather briefing doesn't give me enough detail
my android phones always say "30c", no matter what settings i change - the built in weather thing is just broken.
As far as phone apps go, i don't know any good weather ones. I've never used ventusky on a cellphone, either.
