(Most folks who live near Lake Superior know that the body of water is big enough to have an influence over local weather. But why is that and how does it change throughout the year?)

Lake Superior's influence can be broken into two distinct “seasons” – stable and unstable. These come about because water is slower to heat up or cool down (relative to air) due to its higher heat capacity which leads to differences in sea surface temperature (SST) and the air temperature flowing over it. When the lake is warmer than the air during its unstable season, it warms the air directly above it which can then rise into the cooler air above. When the lake is cooler, defining its stable season, a layer of colder air is present over the water which inhibits air from rising and mixing. This affects many of the weather conditions around Lake Superior including wind, temperature, precipitation, and clouds/fog. Occasionally miniature versions of these same effects are seen on some of our larger inland lakes such as Upper/Lower Red Lake, Leech Lake, Lake Winnibigoshish, and Mille Lacs Lake.

(plus there is a screenshot below via NWS Duluth, Minnesota!)

I consider it moderately northern in latitude. The US is at a lower latitude than most of Europe and Canada.

Wished i had that lake west of me in the summer and the water temps vs my nasty 90+ gulf temps. A west flow would be a great thing then.
