Frost, and the threat of it, has returned to the Upper Midwest.
Gardeners are protecting their veggies. City residents are lamenting the end of summer and the coming of winter.
Farmers are worrying about their crops. Even a few extra days without frost would give still-maturing crops a little more time to reach, or nearly reach, their potential. That can improve yields, quality and profits.
It’s impossible to say how much damage frost this week might do. The answer depends on how far the temperature dips and how long below freezing the mercury stays, among other factors.
One thing is certain: the region’s late spring delayed planting, which means many fields aren’t as advanced as normal and are at greater risk than usual from frost.
