They're everywhere. It's really no point in trying to kill them, it's like plugging a Titanic-size hole with chewing gum.
I read yesterday they're as far west as Kansas now.
NWS Houston is warning of 10-15" if it stalls. The models are in two distinct camps ... you want the one that doesn't stall so it's only 6" and not a mini-Harvey (it won't be anywhere that close, but that's a biblical event)
Little known fact: That radar sensor is actually in @Itstrainingtime's home so it's a combo of a winter night plus his A/C cranking.
(Real answer: Yeah, it's iirc the lowest point in all of York County actually)
