Why are weather apps still so terrible these days?

but its pretty great.
For Seattle area in particular most weather apps will show the entire week as cloudy and rainy, but there is a lot more to it and merrysky is able to surface that.

Flowx has an extremely innovative display of very fine scaled data from a wide range of US, Canadian, EU and other weather agencies (NOAA GFS, CMC GDPS, ECMHWF HIRES, CMC RDPS, CMC HRDPS, DWD ICON Global, NOAA NAM, NOAA HRR, down to 3km resolution). The UI for manipulating the data display is wonderful.
Foreca has a great at-a-glance current and forecast listing.
Rainy Days has excellent recent-to-current radar display.
No relation with any other than happy customer.
It gives me prediction models and large set of data sources in one platform. It's definitely more information than you need than a "weather app" but maybe you can learn thing or two while you are at it even if you are not a weather nerd...
