North Dakota Weather Alert: First Freeze Warning Of The Season Issued For 40+ Counties
BISMARCK, ND — The National Weather Service in Bismarck has issued a freeze warning for more than 40 counties across central and western North Dakota, marking what could be the first freeze of the season for several major cities.
Timing And Areas Affected
The freeze warning will be in effect from 11 p.m. Sunday through 9 a.m. MDT (12 a.m. to 10 a.m. CDT Monday). Temperatures are expected to dip near or below 32°F, bringing a risk of frost and potential damage to sensitive outdoor plants.
Cities under the warning include Bismarck, Minot, and Williston, as well as surrounding rural areas across the Missouri River Valley and northern plains.
First Freeze Of The Season
If confirmed, this will mark the first freeze of the fall season for all three cities. Historically, the average first freeze in Bismarck occurs around September 25, while the latest recorded first freeze happened on October 15, according to the National Weather Service.
Meteorologist Michael Gonzalez said the chance of subfreezing temperatures in Bismarck is “a coin toss, but more likely in Minot and Williston.”
How To Protect Plants And Outdoor Property
The NWS advises residents to protect tender plants and bring potted vegetation indoors. Gardeners should also cover or insulate outdoor crops and disconnect garden hoses to prevent damage from freezing water.
Pets and livestock should be provided with adequate shelter, and homeowners are encouraged to check heating systems and outdoor pipes as temperatures continue to drop into the mid-30s overnight.
Looking Ahead
The rest of the week will feature cooler, seasonal temperatures, with highs returning to the 50s and low 60s under mostly sunny skies. A gradual warming trend is expected toward midweek, but overnight lows will remain chilly through Wednesday.
