I mean, I guess, but how rough of a grid are we talking? This wasn't a tiny city or something... it was a pretty populated city spanning a few miles across in a very populated and well known region. Granted I didn't walk around to check the whole city for rain, but the sky didn't make it look like the clouds were only above my head...
microbursts are a thing. It's entirely possible much of your city was dry despite the cloud cover. Also possible they just done goofed.
O heard it can be as mich as 50 miles if they cheapskate hard
