Update:

For whatever reason, the forecast turned out to be quite a dud. The storms mostly formed up into a line stretching from southwest to northeast, which disrupts the ability of each cell to ingest a laminar/undisturbed inflow, a very necessary ingredient to spawn tornadoes. There were only one or two supercells that produced confirmed tornadoes on the ground in the "high risk" forecast area, which led to traffic jams of storm chasers converging in the middle of nowhere:

This is going to become an increasingly serious problem. Eventually, we'll have a situation where chasers experience mass casualties after trapping themselves in the path of a tornado that's changed its path unpredictably. Something way worse than El Reno (four chaser fatalities, and three of them on a science team). I can't find the tweet, but one of the scientists trying to deploy equipment to study tornadoes complained yesterday that the hobbyists and companies offering tornado chasing tours completely impeded their ability to do science. Even worse, the traffic impedes emergency response crews from saving lives. I consider myself a fun guy who respects civil rights, but we might need to begin issuing storm chasing permits or something(?) that we prioritize to scientists, select companies, and trained spotters. Maybe give cops permission to pull over out-of-state license plates with multiple people in the car, and if they find a smattering of cameras and tripods, boom, that's a ticket. I dunno. It's a tricky problem to fix, but it's time to begin a policy-oriented conversation about it.
