Unfortunately Météo France doesn't have figures yet for how much rain fell – they may be on strike. From Walt's Another American in France site I see that 31mm fell near Saint-Aignan.
There may have been less rain in Anjou and around Sancerre but certainly the Cher Valley got a good soaking.
Yesterday saw some sunny intervals but a little more rain, while this morning it is decidedly cool with thin rain at the moment (10.20am). At noon the temperature is just 12˚C. What a contrast to Wednesday when afternoon temperatures reached 30˚C!
