Baltimore, MD – The National Weather Service in Baltimore/Washington has issued a Freeze Warning for portions of central and northern Maryland and northern and central Virginia, in effect from 2 a.m. to 9 a.m. Saturday, October 25, 2025.
According to the National Weather Service, subfreezing temperatures as low as 29 degrees are expected early Saturday morning. Areas under the warning include Frederick, Carroll, and Northern Baltimore Counties in Maryland, along with Loudoun, Stafford, Spotsylvania, and Prince William Counties in Virginia.
The cold front moving through the Mid-Atlantic will bring the coldest air of the season so far, potentially ending the growing season in several inland counties. Forecasters warn that frost and freeze conditions could kill sensitive plants and damage unprotected outdoor plumbing.
Residents are urged to cover or move plants indoors, drain hoses, and protect outdoor faucets. Pet owners should ensure animals have warm shelter overnight.
Temperatures are expected to rebound into the mid-50s by Saturday afternoon with sunshine returning, but another cold night could follow Sunday morning.
