On Friday, I reported that 93.5 percent of the lake’s surface was covered by ice, according to the Great Lakes Environmental Research Laboratory. The average ice coverage across all five Great Lakes had reached 79.6 percent by then.
Today, after a bit of up and down, 94.6 percent of Lake Superior is covered by ice of varying thickness.
The Great Lakes as a whole? About 88.4 percent. That's still a ways from 94.7 percent in the winter of 1979, according to data from the research laboratory. But it's much greater than what's been seen in recent years.
Here's the current ice cover on each of the Great Lakes:
We've lost 2 1/2 hours of daylight and about 4 degrees off our average high temperature; the sun now as high in the sky as it was in mid-April. No hot fronts are brewing, but today will feel like July; more 80s likely next week. The arrival of cooler air sets off a few T-storms late tonight, but Thursday there will be no doubt in your mind that the atmosphere is shifting gears. More downpours by Sunday? Well, at least the pattern is consistent...
We got a taste yesterday (amazing how good 50F can feel in March). Thursday was an appetizer, the main course comes today and Saturday with low to mid 60s - 25F warmer than average. Some rain moves in Sunday; a bigger storm possible next Tuesday and Wednesday. Heavy rain may end as snow by Wednesday, and some sloppy, slushy accumulation can't be ruled out. Payback for an early spring.
