OK, now that the bulk of the "mainstream" chase season is over, let me make sure I'm correct. I like to quantify these things into hard facts which I will be including on my chaser traffic web page. We had three (3) events this year where chaser traffic reached critical levels...
The bill was introduced but died. I caution everyone on such laws. If they were to pass, I seriously doubt they could be enforced. If for some unimaginable reason they were enforced, even partially, then the only individuals on the road would be the chasing "elite." It's not going to happen.
It is apparently dead, with no action taken since last winter. It didn't even get out of committee for a full vote. However, the wording as proposed is nebulous anyhow. It allowed EM to "monitor and coordinate" volunteer efforts, but it doesn't specifically prohibit chasing either. I'm sure they realized it was largely unenforceable, since anyone can use a public right-of-way unless the road is simply shut down.
It is possible to avoid the crowds sometimes ... this was my view all day on the 21st in Colorado. It's those weekend high risk days that are hard but easier if you stay ahead of the storm. Once a storm hits people it only takes one to slow up the parade. I just try to stay away and only use paved roads if it is a must.
I've seen convergence later in the year farther north. I recall several chases with convergence in June 2014 in Nebraska and not just Pilger.
It does get worse to the south in May, but I do strongly favor the Northern Plains. If June was more reliable and I had better flexibility in my scheduling, at this point, I think I would favor a chasecation in June over mid/late May. One of the main reasons is avoiding chaser convergence, but it's also that June tends to feature slower moving storms and broader, more diverse target areas.
I will say this, chaser convergence has dropped off sharply since May ended, even though some would argue the pattern has also dropped off, aside from a bit of an uptick last week.
