Finland has escaped most of the heat of Central Europe. We have had hard rains occasionally, but overall not that much more rain. From stats look like 100-150% of historic numbers.
So it has really not rained outside the high pressure zone. So I am not really sure where it all would be.
that sounds wonderful from the ~1000 square miles of Phoenix, Arizona, where a century of concrete and asphalt retain so much heat that the clouds bounce around the borders of the heat bubble overhead, unable to dump rain regularly enough to evaporate away the stored heat, but with rainfall regularly visible outside the edges of the metropolitan area, in the wide open skies.
