This sounds like a far cry from what he said last month, but I don't blame him for having reservations about this. Seeing destructive weather is unfortunately a part of a meterologist's job unless they work where there isn't any (if there is such a place), but even more so a storm chaser who is in the line of fire.
Now, if AMHQ (which shouldn't even be here according to the ratings) is the main reason he's holding back, then that may be a horse of a different color. TWC has maintained a leg up on well-intentioned upstart networks because of it's superior live severe weather coverage. Storm chasing is a part of that package. I guess AMHQ beats fishing or gold-mining shows, but that's about all.
