The coldest temperatures so far and first hard freeze of the season are anticipated to begin the week.

According to the National Weather Service, a hard freeze is expected both Monday night and Tuesday night. Some of the coldest temperatures of the season are expected with low temperatures of 20 to 25.

A widespread frost is expected.

Freeze occurs when the temperature drops to 32°-or-lower. A freeze will result in significant damage to many unprotected plants, especially if the temperature remains at-or-below freezing for several hours.

Hard freeze occurs when the temperature reaches 28°-or-lower for at least a few hours. It usually means that many types of plants and most seasonal vegetation will be destroyed.
