The National Weather Service in Green Bay has issued a Frost Advisory for much of northeast Wisconsin, including Door and Kewaunee counties.

The advisory is in effect from midnight tonight until 8 a.m. Friday. Forecasters say temperatures could fall as low as 31 degrees, leading to widespread frost formation.

Officials warn the frost could damage or kill sensitive outdoor vegetation if plants are left uncovered.

You are urged to take precautions by covering or bringing in tender plants ahead of the cold overnight temperatures.

The National Weather Service says additional frost or freeze headlines may be needed again Friday night as cold conditions persist across the region.

Minor flooding also continues across northeast Wisconsin, and forecasters note a small chance of thunderstorms possible Sunday.
