That's been long overdue. I really doubt a few days of rain would make anyone in France forget the rest of this summer.

It was a good amount of rain, but most of it just went straight to rivers as soil is really dry (think if try to get a dry sponge wet again, soil behave in a similar way). It helps but if there are no new rain episodes, water tables will stay low, soil dry in depth and most of the country in a complicated situation regarding water.

"Rain every day" is at best millimeters to tens of millimeters of water (depending on the rain).

You need significantly more to properly saturate the earth, especially after a drought.

The article is talking primarily about Eastern Europe. It's also not inconsistent to say that it's raining during a drought. That's why we distinguish between weather and climate.
