Lake Ice Expanding With Recent Cold

With the recent arctic chill, ice on Lake Michigan is expanding out from the western near shore areas into the open waters of the lake. The high-resolution satellite image below from our friends at CIMSS in Madison from earlier Wednesday shows ice on the lake adjacent to the frozen Bay of Green Bay extending out between 5 and 10 miles along the Wisconsin shore down to around Milwaukee, with the width of the ice growing to between 10 and 20 miles south of Milwaukee and around the southern tip of the lake, which is being obscured by thin high-level clouds.


The thin line of darker blue color right along the shore is a ribbon of open water as the persistent west winds of the past few days has pushed the ice offshore. The eastern half of the lake is obscured by lake-effect clouds, a good indication that the rest of the lake is still open.

The amount and areal extent of the ice is expected to be altered over the next few days by a combination of warmer temperatures and strengthening south winds.
