The big story over the last 24 hours across the county has been the lake effect snow that took place off of all the Great Lakes.  There was a large low pressure system that set up to the north west of the lakes and had very strong winds that wrapped around.  These winds blew cold air from the north over the warm lakes.  In the graphic above, I listed the main areas of snowfall and then listed the last 24 hours snowfall totals from CoCoRaHS.  I also overlayed the the mean sea level pressure from the GFSHD model for this time to give an idea of the winds that were flowing across the lakes on Wednesday.
