With the above normal temperatures we've been experiencing this year, Lake Superior has remained relatively unfrozen. In fact, compared to recent years, this is one of the least amounts of ice cover we have seen in February! Check out the MODIS image below to see how little of the lake is frozen as of yesterday afternoon (Feb. 7)...
Also note the band of lake effect clouds that formed across the eastern half of the lake and affected north central Upper MIchigan due to a predominate northerly wind direction. This sparked some lake effect snow showers overnight Feb. 6 and during the day Feb. 7. This is a very good example of how lake effect snow showers take on a "banded" appearance, with some thicker bands and some lighter bands of snow and clouds, and the potential for breaks in between.
