Snowfall reports and maps for the late week-storm with a lot of sleet/freezing rain north of L.I.:

To show the evolution of the Friday/Saturday storm, I have picked half of the Euro ensemble members and included the maps below starting Friday afternoon and ending early afternoon Saturday.

Here are the Long Island snowfall reports as my forecast seemed to work out quite well overall:
