The 4pm Burning Law is in effect February 15 through April 30.

This law bans open-air burning prior to 4 p.m. if the fire is within 300 feet of the woods or dry grass which could carry fire to the woods. Burning is allowed between 4 p.m. and midnight as long as the burner takes proper precautions and attends the fire at all times. Violation of the law is a Class 3 misdemeanor with a fine of not more than $500. 

The reason behind the 4pm Burning Law is that debris burning is the number one cause of wildfires. Wildfires are more likely during late winter and early spring because winds are usually elevated, the relative humidity is lower, and the fuels on the forest floor are extremely dry.
