I got to meet him as a senior at Penn Manor while studying met in high school. It was a brief exchange but one that left a lasting impression on me.
I consider Horst and Paul Knight (Weather World lore) to be the 2 greatest mets I've watched/listened to in my lifetime. Both were 100% objective and deadly accurate. The Blizzard of 1996 - as I recall, almost every model showed that storm missing us to the south pretty much the entire week leading up to the storm. It was only in the final 48 hours or so that they all suddenly adjusted north. Days before that on Weather World, Paul said in that night's extended forecast that the southern half of PA was going to get obliterated. He was the first to call it...and history shows he was spot on. That wasn't the only time he went against everyone/everything else and was right.
Horst was uncanny at predicting events that featured snow mixing or changing over to ice and rain - he would harp on that for days leading up to the event when no other model or met would see it. Like Knight, he was right just about every. single. time.
