Not a tropical cyclone?

By: Stu Ostro, 4:59 PM GMT on August 15, 2015

This isn't the first time I've written about this.  In fact, it's the fourth: 2009, 2011, 2013, and now again in 2015.

The latest episode(s) ...


THING #1

On the morning of Monday, July 27, the more I looked at the thing that was in the northeastern Gulf of Mexico, the more it seemed the circulation was that of a low pressure system with tropical characteristics.  I was going to tweet that it was a "tropical low."

Upon seeing the result of that flight from Boston to Salt Lake City which was diverted to Denver last night (Friday, August 7) because of hail damage, I investigated further, having been a meteorologist on many flights in which I thought, "They're going to fly through THAT??"  This case seemed different, in that Beau (tweet above) was quoted as referring to flying between...
