GRAND FORKS, N.D. — A Frost Advisory remains in effect until 9 a.m. Monday for much of eastern North Dakota and northwest Minnesota, where overnight temperatures are expected to fall into the lower 30s. The coldest air of the season so far could bring widespread frost, threatening gardens and late-season crops.
According to the National Weather Service in Grand Forks, the advisory includes Grand Forks, Fargo, Grafton, and Thief River Falls. Calm winds and mostly clear skies will allow heat to escape quickly overnight, creating ideal frost conditions. Homeowners are urged to cover tender plants or move potted vegetation indoors to prevent damage.
By Monday afternoon, temperatures should rebound into the mid-50s under mostly sunny skies, but another round of frost is possible Tuesday and Wednesday mornings. The Weather Service notes the pattern of cool nights and sunny days will persist through midweek before warmer air returns by Thursday.
