DENVER (KDVR) — The National Weather Service issued an overnight frost advisory for several areas surrounding the Denver metro area, along the Front Range and eastern plains.

The advisory is from 2 a.m. to 8 a.m. as temperatures in the Denver metro area are forecast at a low of 40 degrees. The Palmer Divide south of Denver and South Platte River Valley northeast of Denver will see even colder temperatures in the low to mid 30s.

Frost formation typically happens when temperatures fall into the low to mid 30 range.
