Right now, if you are a tourist walking around Paris anywhere near "La Tour," as it is affectionately known, you are about to get soaked. So this gorgeous threatening sky is something à détester. But if you happen to be sitting under the awning of a particularly winsome café, sipping a lightly chilled kir or a glass of pastis, you are probably very happy indeed.
*Update: As predicted, it rained buckets on Friday, minutes after the above photo was taken. Click to see la pluie on the steps outside the Lamarck métro station!
