It's because the current administration cut NOAAs funding, which means fewer weather balloons, which means less data to make a prediction. And it means less real time updates. So yeah, when it rains, it might take a few hours for that to flow into your weather app. It's a direct result of DOGE.

>and every other app I check shows it. Other apps have a different government?

From my experience, it's quite hit and miss for every app.

If you use Google 99% of the time and only check other apps when Google is wrong, then that's a biased experiments.

There is little to no evidence that the current degradation of the US upper air backbone is regularly contributing to degraded forecast skill. That might change as we head into the more active northern hemisphere winter.

There was a lot of evidence last winter. But with the active El Niño it’s starting earlier this year.

Please share some of that evidence.

It's great that they're working on this, but I am puzzled at how absolutely awful the forecasts are in the Google weather app for my area. The forecast will show no rain, the radar view shows nothing, meanwhile it's pouring outside and every other app I check shows it. I know I can't expect it to be perfect, but being terribly wrong even one in ten times is enough to tarnish its reputation permanently.

This isn't a super serious comment (and an opportunity for someone to speak up on this) but... I've heard some commentary in the past that 5G interferes with data measurements heavily used for weather forecasts (something about satellite measurements?) I remember being _very_ impressed like 15 years ago about how I would have _hourly_ weather forecasts (in particular around the rain) that seemed like magic! And then…

A couple of years in Tokyo gave me great trust in certain weather apps for eerily precise minute-by-minute rainfall predictions. After a few years back in Sydney, my trust in them has dropped back down to the usual uncertain baseline, and my reliance on them has been mostly replaced with my own rough assessment of the air and sky.

On recent visits to Tokyo, with my current habits, the general crowd (who presumably check some app) has been the more reliable forecast. Either everyone has an umbrella in their hand or they don't. And I discover whether I should have brought my umbrella or if I'll be lugging it around pointlessly, just far enough from my hotel to be stuck with my choice

That's because NOAA are not doing the tests that would produce such evidence.

There's reduced data available for initial conditions, so I wonder how that will effect things: * https://apnews.com/article/weather-forecasts-worsen-doge-tru... * https://www.independent.co.uk/news/world/americas/us-politic... A good book on the history of forecasting, The Weather Machine: A Journey Inside the Forecast : * https://www.andrewblum.net/the-weather-machine-2

Don't plenty of android devices have barometers? I expect Google being Google and recording all that data unless you opt out.

Would that be practical for weather forecasting or not really?

It’s crazy we’ll never have forecasts as good as dark sky again. What kind of magic were they doing?

Dark sky was awful and all of its acclaim comes from confirmation bias. In seattle I'd see its forecast change by the minute. The whole point of a forecast is to know what will happen and if that keeps changing, then we do not know.

The only forecasted rainfall for local areas within a very short timeframe. This made it possible to utilize simple factors to predict the near future. It is built into Apple Weather after Apple purchased them.

> It is built into Apple Weather after Apple purchased them. Did Apple lobotomize the tech when they integrated it, or lose access to whatever upstream data Dark Sky had access to? Apple Weather is comically bad (though not nearly as bad as Google's weather searches).

Apple Weather (followed by Xweather (formerly Aeris Weather)) seems the most accurate forecast for Prague when it comes to TP/FP for rain in Prague by my long term experience when I compared multiple data sources
