Milwaukee, WI — The first significant blast of cold air this fall has triggered freeze warnings and frost advisories across a massive stretch of the central and eastern United States, with temperatures plunging into the low 20s in some regions, according to forecasters.
The National Weather Service (NWS) said advisories extended from northern Kansas and eastern Nebraska through parts of North Carolina, Virginia, and Maryland. Some warnings were active Thursday, October 23, while others were expected to begin Friday, October 24.
Bitter Cold Grips Midwest and East
Forecasters warned that overnight lows in Wisconsin, Illinois, and Iowa could reach 27 degrees over the next few days, with some isolated areas dipping even lower — near the teens. Meanwhile, areas across western Virginia, West Virginia, and the Carolinas could see temperatures as cold as 25 degrees.
“Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing,” the National Weather Service office in Milwaukee cautioned.
The weather agency added:
“Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered.”
A forecast map released by the NWS showed the cold front expanding eastward through October 23, marking a sharp end to the growing season for millions of Americans.
According to USA Today, this widespread early-season freeze could affect both residential areas and agricultural operations, signaling the arrival of winter conditions earlier than usual.
Understanding Frost and Freeze Warnings
The National Weather Service distinguishes between frost advisories and freeze warnings based on temperature severity and potential impact.
- Frost Advisory: Issued when temperatures are expected to drop near freezing (33–36°F). These conditions can lead to the development of widespread frost, potentially damaging sensitive plants.
- Freeze Warning: Issued when temperatures are forecast to fall to 32°F or lower, signaling the end of the growing season and possible extensive plant damage.
“A freeze warning generally means it’s too late to save most crops,” forecasters explained. “Homeowners should prepare gardens and outdoor systems accordingly.”
Protecting Your Home and Garden from the Freeze
The abrupt cold snap isn’t just a concern for farmers — it can also threaten home plumbing systems and landscaping. Experts advise taking simple preventative measures to protect against freezing pipes and vegetation damage.
Here are a few ways to prepare your home for the cold:
- Wrap exposed pipes using towels, foam, or makeshift insulation.
- Open cabinets under sinks near exterior walls to let warm air circulate.
- Maintain indoor warmth overnight to prevent freezing in unheated spaces.
- Run a small stream of water from faucets with vulnerable pipes.
- Cover sensitive outdoor plants or bring potted plants indoors.
“Water expands as it freezes, which puts pressure on metal or plastic pipes that can cause them to break,” the NWS warned.
End of the Growing Season
With frost advisories now stretching from the Plains to the Atlantic, meteorologists say this system officially marks the end of the 2025 growing season for large parts of the U.S. Midwest and Mid-Atlantic.
Communities are urged to continue monitoring local forecasts and prepare for potential record-low temperatures as fall gives way to early winter conditions.
