A strong push of autumnlike air will invade the North Central states this week and will bring the risk of frost, as well as the chance of a bit of snow to some locations.
The chilliest air since last spring will push southward from Canada and across the northern and central Plains, Midwest and the eastern slopes of the Rockies, prior to the middle of September.
The chilly air will follow an expanding cooldown already in progress and will follow a large area of rain forecast to sweep out of the Southwest.
A patchy light frost will visit portions of the northern tier states over the Central states beginning Friday.
According to Senior Meteorologist Dale Mohler, “The frost will be mostly a concern for backyard gardens, where tomatoes, squash and other sensitive vegetables and flowers are flourishing.”
Temperatures are forecast to dip into the 30s in rural areas of the Dakotas, Minnesota, Wisconsin and Nebraska.
