So this coming weekend I’ll be attending an annual car meet here in Japan. Flowx says Saturday will be very heavy rain in my area, yet Yahoo weather says it will only be cloudy. Does Flowx sync with such data from Yahoo etc?
Been using the app for years, love it and find it accurate 99.9% of the time, but just need to know if polishing my car is worth doing this week. 
Hi and welcome to the forum,
No, Flowx does not sync with Yahoo or any similar weather sources. Flowx shows the raw data from weather simulations. Places like Yahoo take all this data and uses statistics and a bit of magic sauce to improve the predictions, but this is only big cities and towns, i.e., you loose the big picture on the map and the understanding of what is causing the weather.
Check out What is Flowx?
Cheers, Duane.
