What happened

The episode as NWS PAH wrote it up.

This was the third of several freezes on consecutive nights that resulted in extensive damage to some crops, gardens, and even trees. Record warmth in March preceded these freezes. Most growth was well ahead of schedule when the record cold struck. A large Canadian high pressure system drew unseasonably cold air into the region for several days. A hard freeze occurred during this third night of the freeze, when low temperatures were in the mid 20's. Significant damage occurred to vegetation.
