Lake Michigan in 2014 |
From the Chicago Tribune:
The Siberian Express that's imported northern Russia's weather into North America is leading to a second year of fast-growing ice cover on the Great Lakes, setting up the Chicago area for the possibility of another cool spring.
By Wednesday, the Great Lakes were 85.4 percent ice-covered, just above the 85.2 percent on Feb. 18 last year, according to the Great Lakes Environmental Research Laboratory. With below-average temperatures predicted for at least the next week, the lakes could approach last year’s levels of 92.5 percent ice cover, the second-highest level since records began in the early 1970s.
It's far from the only factor in spring weather, but a heavy and late ice season can lead to a cooler spring—and even a cooler summer, forecasters say.
