Great Lakes Observing System

For anyone who doubts the power of the Great Lakes, now's the time for a reset.

This week, data buoys on Lake Superior recorded 28.8-foot waves, according to the Great Lakes Observing System.

This winter brings the latest installment of the Star Wars franchise, full of familiar costumes, familiar villains, and the familiar "pew pew pew" of space guns. But you can skip the movie theatre and still hear those iconic blaster sounds if you visit a frozen lake.

This cool satellite image from the NASA Earth Observatory, taken on Dec. 14, shows a veil of clouds over the western Great Lakes.

NASA captured the image with the Visible Infrared Imaging Radiometer Suite. NASA says it can detect "faint light sources — in this case, the reflection of the full moon on the fresh snow."

New heat maps from NOAA show the startling change in water temperatures across the Great Lakes this year.

Back in 2014, the heat map shows a bluish scene, illustrating cool temperatures. But this year, the map in late November temps is all yellows and oranges.

The National Weather Service says the season's first lake effect snow is likely this weekend. That could be a harsh beginning to winter.

In the Great Lakes region, the effect kicks in when dry arctic air speeds over large expanses of warm water.
