Weatherbug and wwl shows different data

From 10 days~, I see that wwl shows X% chance of precipitation, but on weatherbug site precipitation % is different.
Here is picture of current weather forecast.

WeatherBug station:
WWL version: 7.2.43

Weather Watcher refactors the daily precipitation a bit, so it might not always match If the precipitation is different in the hourly forecast, then Weather Watcher shows the precipitation from the hourly forecast.

That explains why you’re seeing 10% in the daily forecast right now.

Okay thanks for the explanation, Mike.
