Widget showing rain in the hour with Météo France data

I might be looking for a five-legged sheep: as a cyclist, I need to have immediate access to rain coming in the hour.

I have that with RadarWeather’s widget (RadarWeather | F-Droid - Free and Open Source Android App Repository), but the data comes from OpenWeatherMap and is not perfectly accurate.

It would be more if using Météo France’s data.

I can get data from Météo France using Geometric Weather (Geometric Weather | F-Droid - Free and Open Source Android App Repository), but no widget with rain forecast.

Any idea how I could have a rain widget with Météo France data?
