I knew someone who used to work with him I think while at Accu-Weather, and he didn't care much for JB either. Thought JB had good knowledge but was a bit arrogant and always "CYA" for anything he got incorrect, saying things like, "well, I got the pattern right but the meteorology wrong!", or something along those lines.
I've mentioned this before but he'd always use the weasel words such as "coldest month...RELATIVE TO AVERAGES". I swear once he used that to claim that March was the "coldest month of the winter" (RELATIVE TO AVERAGES, mind you!), and then claim victory that his call for a "very cold 2nd half of winter" was correct or whatever. I used to joke that using his logic, I could claim a rather cool July is the coldest month of the year, relative to averages!!!
