The problem is, Brad routinely posts vlogs when there is an upcoming system of any significance. In that video, he explains, in an easy to understand way, the reality of the forecast and what may or may not happen. However, people do not take the time to watch or listen and instead will believe a fantasy model they see posted. I'm sure this is super frustrating as a broadcast met.
He is trying to do his best to debunk taking those maps for face value. I think this is a great way to illustrate it.
