Frost and Freeze Warnings Issued Across Central US Ahead of Early Fall Chill
5 Sep
Summary
- Frost and freeze warnings issued for 4 states
- Temperatures could dip below freezing, harming crops and plumbing
- Unseasonably cold weather arrives a month earlier than normal

On September 6th, 2025, a cold front has swept across the central United States, bringing unseasonably low temperatures that have triggered frost and freeze warnings for several states. The National Weather Service has issued advisories for Minnesota, North Dakota, South Dakota, and Wyoming, cautioning residents that overnight temperatures could dip as low as 33°F, leading to frost formation, and in some areas, potentially reaching a freezing 29°F.
The early fall chill is arriving about a month earlier than normal, according to NWS meteorologists. In North Dakota, the freeze warning covers much of the western and central parts of the state, where sub-freezing temperatures could damage crops, sensitive vegetation, and unprotected outdoor plumbing. Similar frost advisories are in place for overnight hours in the other affected states, including parts of South Dakota and Minnesota.
This abrupt shift in weather patterns is in stark contrast to the extreme heat wave that has been gripping the Pacific Northwest in recent weeks. While some regions are experiencing an early taste of winter, others are still grappling with the lingering effects of summer's scorching temperatures.
