lake-effect snow

I never heard that term so I checked Wikipedia. That was a mistake. This is far better - there's a big, simple graphic: What is a Lake Effect Snow?

Rant. I love Wikipedia but the editors can be annoying. Many of the most active editors must hate simple graphics or charts, etc at the very top of the page. If a visual aid is there right at the top of the page - a lot of people spend a lot less time reading their edits. Maybe they leave the page nearly right away. The editors want you on the page reading their edits.
