More ice and less snow Monday night/Tuesday morning in CNY, but why?

Weather

Yes, much of CNY had less snow than expected late Monday night thanks to the more northerly storm track which caused milder air to move in aloft and at the surface to move in quicker for many overnight.

This resulted in a quicker changeover to sleet and even freezing rain across the region late Monday night hence the glaze to as much as a quarter of an inch of ice was caked on top of the snow when most woke up Tuesday morning. The most significant icing and least amount of snow occurred south and east of Syracuse.

Below are some snowfall and ice reports from the National Weather Service…
