As the sun rose over the eastern U.S. this morning, @NOAA's #GOESEast 🛰️ watched bands of lake-effect snow streaming off the #GreatLakes, which have been dumping heavy snow across the region. Farther south, can you spy wave clouds rippling over the Appalachians in this 4-hour loop?

Why are #GreatLakes water levels going down? Are water temperatures warmer than normal? What kind of winter will we have?

RT @NOAA_GLERL: Happy New Year!! 🎉

2024 was a wonderful year full of innovative #GreatLakes research, made extra special by the celebration of our laboratory's 50th anniversary. We can't wait to continue our Great Lakes science in service to society in 2025!

Winter is becoming shorter in the waters of the #GreatLakes!
This finding marks the first time researchers have used subsurface temperature readings to determine how climate change may be affecting seasons in & around the Great Lakes.

We hope you're staying warmer than the #GreatLakes are this week! Ice cover on the lakes is currently at 20.8%, just about average for this time of year.

Ice cover by lake:
Superior: 9.5%
Michigan: 20.3%
Huron: 26.7%
Erie: 58.2%
Ontario: 7.1%

For #TimelapseTuesday, @NOAA's #GOESEast 🛰️ took advantage of mainly clear skies to capture 8 hours of lake ice moving on the #GreatLakes from Feb. 1. More than 50% of the Great Lakes were covered in ice as of Sunday, with shallow Lake Erie having over 95% coverage. #GOES19 https://t.co/jLpPdZkwJN
