I found this interesting...

I was thinking about a winter storm that went through norhtern Minnesota a week or two ago and I remembered seeing a product from the Marquette NWS that was called a "Heavy Freezing Spray Warning" for counties along Lake Superior in the UP of Michigan. Unforutnately my computer was acting up and I couldnt read the warning text. Anyways, I thought this was pretty interesting since I have never thought about anything like this but I suppose it can be problematic. Im guessing they are talking about the spray of the waves crashing on shore, I dont know what else they could be talking about. I've never seen or heard about this, but then again we dont have to deal with it here in central Minnesota. So I was wondering, what is the criteria for a "Heavy Freezing Spray Warning"? I wonder if its some sort of weather phenomona that requires a specifc set of weather conditions? Or is it something that happens rather regularly along the shores of the Great Lakes? I was also wondering what problems these conditions would create? I mean, I would assume that these conditions and consequent problems are pretty much confined to right along the shore but maybe winds could carry the mist/spray farther inland? If anyone knows I think it would be pretty interesting to learn about, especially because like I said before it not something we ever really think about for those of us who dont live along the shores of the GL.
