What happened

The episode as NWS PAH wrote it up.

An unusually late season frost affected most of southern Illinois except for the three southernmost counties. Temperatures fell into the mid 30s. Many unofficial readings from 34 to 36 degrees were recorded. This was the last of four consecutive frosty mornings. Lows each morning from May 1st to the 4th were about the same, mostly in the middle 30's. The combination of the cold weather and much lower than normal rainfall slowed the development of some early-planted corn and soybeans.
