(WXYZ) — If you have already started planting, listen up! The chance for frost returns tonight.

A Frost Advisory has been issued by the National Weather Service for most of Metro Detroit, excluding Wayne, Lenawee and Monroe Counties. The advisory is in effect from 2 a.m. to 8 a.m. Saturday.

Temperatures are expected to drop into the 30s overnight, making frost a possibility in the advisory areas.

A Frost Advisory is issued when the low or minimum temperatures is forecast to fall between 33° to 36° with a clearing sky and light or calm winds. It's issued in the spring during the growing season when it is late enough to cause damage to new plants and crops. Remember, the average date for the last frost across much of metro Detroit extends into late May and we're not there yet!

While we are only expecting a light frost, you may still want to take some actions to protect your plants. I would bring any hanging baskets or potted plants inside the garage, so any new growth won't brown if frost does develop.

For those of you who have hustled to get plants in the ground, you can use bed sheets, drop clothes, blankets or plastic sheets to make suitable covers for vulnerable plants. Use stakes to keep the cover from touching foliage. However, a thorough watering will prevent desiccation and act as an insulator to the soil and plants.
