Scientists think that may be the case, looking at the ice on the Great Lakes as an indication.
Researchers say lake ice is usually gone by May. Last year, however, ice lingered into June.
If that happens again, we're likely to have a cool spring.
So far 85 percent of our lakes are covered in ice. With the below-average temperatures forecast for the next week, we could approach last year's levels of 92.5 percent ice cover.
