They are. Usually very newswortht when they become major events. The US suffered hundreds of billions in damages in the last 3 years from intense snowstorms in places that very rarely if ever get light snow, getting real snowstorms (laughs in Canadian).

We also have been having arctic lows mixed with warm air causing freezing rain and dangerous conditions in our much shotened winter.

Melting ice cools the air arround it making for colder oceans and atmospheres in summer months. Usually lots of shelf ice melting can impact sheet ice development.
