For those who are wondering why this got posted here, it is because Dr. Frank had a doctorate in optometry (not to mention a few other science-related degrees.) Besides his weather gig, he was the science news guy for NBC in the day.
I grew up watching him on TV and he was the go-to meteorologist if only because he explained the "whys" in easy-to-understand science language. Somehow, he seemed to get the forecast more accurate than his peers. Just no reason to get your weather fix from anyone else.
