Impressive lake-effect cloud and snow plumes across Lake Superior
Arctic air interacts with still relatively ice-free warmer waters on Lake Superior
Our arctic air mass played cold weather tricks across Lake Superior Tuesday.
Lake Superior is still about 90 percent ice-free. That’s way below the historical average ice cover for late January.
Subzero air temperatures in the morning wafted across lake temperatures in the 30s above zero.
That made for some interesting atmospherics just above the lake's surface as the relatively warmer water transferred heat and moisture into the frigid air layer above.
As southwest winds persisted, long strands of lake-effect clouds and squally snow developed across the length of Lake Superior blowing eastward into the Canadian side of the lake.
The National Oceanic and Atmospheric Administration’s NAM 3 km model picks up the progression of the lake-effect snow bands drifting into Ontario overnight.
Weather never sleeps. And Lake Superior never ceases to interact with our Upper Midwest air masses.
