As chilly air takes hold in areas from Denver to Minneapolis and Chicago, much cooler air will expand to areas from Dallas to Atlanta and New York City in the coming days.
The chilliest air since last spring will continue to advance southward and eastward over the United States to end the week. Some areas of the Rockies and Plains will also have the first snow of the season.
Temperatures were hovering in the 30s over much of Montana with snow falling in some locations, including Cut Bank and Lewistown, on Wednesday.
Snowflakes are forecast to fall around Denver with a coating possible in the foothills and areas north of the metro area during Thursday night into Friday.
The outbreak will bring a freeze to portions of the northern High Plains and the risk of frost to areas farther to the east and south over the northern and central Plains.
According to AccuWeather Senior Meteorologist Dale Mohler, “While a freeze will not reach areas where major crops have not reached maturity, scattered frost will be a concern for backyard gardens over the North Central states.”
