I had to check myself yesterday after a bad day, but this happens with every major storm. Model prints out monsterous solution, waffles to minimal impact, and eventually comes around to close to the initial solution or exactly there. I am not saying this is going to be the case, but I'd be willing to bet (we can audit this via the old threads, my memory is fading anymore) that over the past three or so weekend blockbusters, Wednesday and Thursday were when the tide of rain was washed away.
The Weather Channel in particular is seemingly going all-in on this one. I'll begin sounding the alarm if/when Horst comes around.
