Key Takeaways:

Prioritize visual thunderstorm avoidance by staying VFR (on top or below bases), observing dark skies/lightning, and using ATC/PIREPS, as in-cockpit Nexrad data is significantly delayed (up to 15-20 minutes) and unsuitable for tactical maneuvering through severe weather.
In an inadvertent thunderstorm penetration, immediately slow to maneuvering speed, engage anti-ice, keep wings level without chasing altitude/airspeed, secure loose items, and declare an emergency to ATC stating your actions (e.g., climbing/descending) without waiting for permission.
