Below are a couple of pictures from the beginning of March 2005. One is The Detroit River at flood stage and the other is Chicago Sky Line with snow. Needless to say if this level of perscipitation continues there won't be streets in cities anymore there will be waterways such as Venice, Italy.
The problem is those structures were never built on stilts to survive long term exposure to water. In the case of Boston if the salt way wedge gets to higher volumes than any fresh water bays, the city will lose not only it's fresh water fisheries, lakes and streams it will lose it's fresh water supply.
The other aspect of this chronic Great Lakes issue is to note the Chicago picture. In the background is a very, very low hanging cloud bank. It could be argued the peculiar cloud bank is just snow falling and that might be but the foreground of the picture shows no other snowfall.
The point is I have observed many cloud banks like this and have some pictures of same which I need to post to this blog, but, that is characteristic of a dense Global Warming System with losts and losts of varying layers of complex air systems above it. They also have the characteristics of pre-tornadic activity.
