Key Takeaways:

Despite the author's pre-flight weather analysis recommending a "western" route, the flight was assigned an "eastern" route directly into a developing nor'easter with predicted adverse conditions.
The flight encountered significant challenges, including rapid clear ice accretion and severe turbulence between 4,500 and 8,000 feet, attributed to a strong vertical wind shear and an unstable atmospheric layer.
The aircraft successfully diverted to Richmond due to the severe conditions, where post-flight analysis confirmed the meteorological cause of the turbulence.
The experience reinforced the importance of proactive route negotiation with ATC and remaining diligent in minimizing exposure to adverse weather, especially by flying below unstable layers.

Over the last 25 years, I have been asked to speak on various aviation weather topics at dozens of aviation events and gatherings.

During these events, it’s quite common for a pilot to walk up and ask me about how I handled my most challenging flight as it relates to weather. Maybe they were expecting to hear something juicy; I don’t know. While I don’t want to disappoint them about a harrowing recount of one of my prior flights, my response is usually the same. I don’t have such a story since I am always diligent about minimizing my exposure to adverse weather when I am the pilot in command (PIC).
