What happened

The episode as NWS PBZ wrote it up.

Ice began to build up on the Allegheny Rivers and its tributaries since January 11th. Below zero temperatures on the 18th and 19th rapidly increased ice development. On the morning of the 23rd, ice began to move out of Oil Creek, a tributary of the Allegheny River, and became jammed downstream near the mouth of the Allegheny River. Low-lying areas and some basements in Oil City flooded as water levels behind the jam rose. Three homes and a couple of businesses were also evacuated. The ice began to break up and water levels fell early in the afternoon.
