The latest NATICE graphics show Lake Erie totally covered with 9/10+ ice, Lakes Superior and Huron are nearly totally covered with 9/10+ and Ontario about 80% covered with 7/10+. It is likely Superior and Huron will join Erie with total coverage of 9/10+ in today or tomorrow's report.

It is possible Ontario could do the same as it is experiencing near or sub-zero temperatures tonight.

The NATICE daily reports are posted about 5:00pm EST. Link is here:

It is an unusual event for 3 of the lakes to freeze over, which only happens once every 6 to 8 years. Four or more freezing is a most unusual event.
