Lake Superior's effect on the weather..

How does Lake Superior effect the temps around the lake? many have asked this through last few weeks..The one who would know this better is Tim since he lives up there,However since I spend a lot of my free time on and around Lake Superior I will take a stab at it.....
Ok one has to remember Lake Superior is the deepest fresh body of water in the area...With the lake being over 1000 plus feet deep in spots..Most around 400 to 600 feet deep...That is a lot of cold water for the sun to heat...All lakes are always changing,however one will notice that up on or near the shore of Lake Superior...When the winds blow off the lake to the shore areas it is picking up all that cold air the lake has to offer..Hence this keep the temps down near the shore...There have been many times when I was 15 to 20 miles away from the lake and the temps were in the 90s...Once you get within 2 to 10 miles the temps dropped into the 50s/60s depending on how strong the wind is off the lake...This will at time cause a very thick fog bank to move into parts of that area..Now the same hold true in the winter....Temps on and near Lake Superior are warmer than down here...Reason is cold winds blowing over the warmer air of the lake does warm up some...Also this can produce a lot of LES is the fletch is just right along with the delta's...I will hit that topic harder towards next winter...Was it strange many time being up in Duluth on the big hill temps were nice and hot...Drive down the hill instant cold..If one never had the chance to see that first hand,I tell you it's the one thing you will never forgot in your life time...Now some have asked does Lake Superior have any effect on our weather here in Barron County....Well it sure does,just not to the degree it has one gets past Minong....Our temps really don't get effected by the lake...It's more of the moisture..Winds flowing on the lake just right can bring down drier air into the area...No moisture left by time the air makes it this far South..All it takes is a large ridge of high pressure sitting close to Hudson Bay Canada...This mainly happens in the spring and fall for this Barron County...Now in the winter we can get some LES this far South again it all depends on the fletch off the lake and how much moisture is left..As rule we needed to have very cold temps down here for that to happen and the winds have to just at the right degree to have LES...Now we won't see inches or feet,but we could see flurries or a dusting of snow from such event...Ok that's my stab at it...Like I said before Tim knows this better than me..So Tim add to this..Correct me if I'm wrong on any of this...
