Narrative:

Pitot/static failure that led to an air data computer shutdown. Did not have accurate air speed or vertical speed and lost all instruments at various times.ATC helped me to get to VMC and then safely land at ZZZ1.I believe the root cause was the plane being exposed to heavy rain; high humidity and then temperatures significantly below freezing in a short period of time. The condensation froze and partial blockage of the pitot system resulted.lessons learned; the plane will be hangared during very cold or inclement weather.
