I’m surprised how many places in the world measure rain in percentage chance. Must be a metropolitan concept. Here in Denmark, weather reports estimate mm/hr - the amount of rain. Maybe it’s our agricultural inheritance?

The two things are not strictly related, you could have 30% chance of heavy rain, or 90% chance of light rain. Both are needed and many apps have both.

Dark Sky was a marvel, and when it first came out, its ability to say rain will start where you are in 2-3 minutes was a marvel. The information design argument is 100% valid, but I also marvel that, having bought the company, Apple's weather app still isn't as precise or accurate. I don't know whether Apple's privacy focus prevents them making the same precise predictions, or if there is some other reason they don't…

Agreed, that’s what won me over to Dark Sky. Now I use Carrot Weather and like that a lot, the “it’s going to rain hard in XX minutes” notifications are awesome, especially with a dog. I’ve gotten that notification close to a normal time I’d take the dog out and been able to run him outside before it pours rain for the next hour.

> Apple's weather app still isn't as precise or accurate Is it not? The rainfall-per-minute over the next hour on iOS seems about the same accuracy as Dark Sky had -- I used Dark Sky for years. It wasn't perfect but it worked well enough, same as iOS did after. You can even scrub the precipitation map predictions and they look the same to me. I know the Dark Sky prediction accuracy was greatly dependent on where you…

Dark Sky would say “Light rain staring in 4 minutes and ending in 17 minutes” and that’s what would happen.

Apple Weather is nothing like this.

I am surprised no one mentioned Carrot as a replacement! I have been using it for years. they don't have their own source of data, they are mostly a good UI, and you need to select a data source like Apple Weather or others.

They also added the "Inline" theme which is a copy of Dark Sky's

Most places I look at report both probability and give a measurement prediction. So it would be like "60% chance of rain after 2pm, total amount less than 1/10th of an inch"

Meteoswiss has timeserie histogram with of amount of rain with confidence intervals (10th and 90th quantile)

It tells you all you need to know at a glance :)

it always felt to me like the major innovation behind darksky was the clever exploitation of newly broadly available precision gps. prior to darksky, i'd look at the radar picture on my smartphone and the pin where i was to try and figure out when it would start raining, darksky seemed to just package this really nicely with visualizations and notifications.

(and yes, the visualizations were beautiful, but the real key was being able to see exactly where one was with respect to the radar picture and to be able to use already existing forward predictions of the radar picture in conjunction with precise gps to generate timeseries/events.)

It's amazing to me that nobody has been able to match their UX (Apple in particular - how did they fumble the acquisition so badly?). The Weather Channel by most accounts has the best model but one of the worst websites of all time. live.xweather.com (formerly Aeris) is kind of close, but is basically an ad for their API/commercial subscriptions and not really built for day-to-day use. Some of the open source clones have the UI 80% of the way there but their forecasts aren't as accurate.

I've settled on using the built-in Android weather app, but it pales in comparison to Dark Sky, in every respect.

Earlier quoted context omitted.

I agree. One of the weird things is that the precipitation map will show rain coming that doesn't show anywhere else in the Weather app. Nearly every time that happens, the map is the one that's correct. And usually forecast.weather.gov will align with the map as well (and provide a better forecast than the app).

But that's the point. The map is based on the Dark Sky algorithm and only goes out an hour or so. And that's where the next-hour precipitation graph comes from -- and I've never seen them not match. Everything else is standard weather forecasts. Dark Sky itself worked the same way. It wasn't making 6-hour forecasts using its 1-hour algorithm. The results would have been terrible. This is why I don't understand the co…

to each their own, but i used darksky for years as a daily bicycle commuter and found it to be profoundly accurate--to the point where i could use it to find clear patches of 15-20min to ride home in. there was a marked decline in the reliability & accuracy of the information provided to me once i was forced to switch to apple weather
