Saturday night should have a lower chance of showers in the area. Coverage will be more scattered, and showers will be lighter. The threat of thunderstorms will also diminish. Scattered showers will continue around northern France through Sunday, and there may be some breaks in the clouds that allow some sun to briefly shine through.
I will be travelling on vacation with family tomorrow, so I won't be able to post radar updates as I usually do. I recommend this site to monitor radar - https://www.meteo60.fr/radars-precipitations-pluie-france.php
